Do ‘sliders’ slide and ‘tensioners’ tension? An analysis of neurodynamic techniques and considerations regarding their application

Short term effectevness of tibial nerve flossing technique in patients With tarsal tunnel syndrome

ObjectiveTo examine the short-term influence of adding tibial nerve flossing (TNF) technique to conventional therapy on foot pain, Dorsiflexion-Eversion (DF-E) test, ankle range of motion (ROM), and tibial nerve conduction study (NCS) in individuals with Tarsal Tunnel Syndrome (TTS).MethodsThis was a parallel randomized pre-post-test single blinded controlled trial, included 54 individuals with TTS randomized into study and control groups. Both groups received conventional therapy including transcutaneous electrical nerve stimulation (TENS), therapeutic ultrasound (US), gastrocnemius (GC) muscle stretching, and foot arches supports/wedges provided as needed with an additional (TNF) technique provided for the study group. The intervention was 3 days/week on alternate days, for a four-week duration. Pain severity and DF-E test as primary; ankle dorsiflexion ROM and tibial NCS as secondary measures, were collected pre- and post-treatment.ResultsWithin-groups comparison showed a significant improvement in all tested variables. Post-treatment between-groups comparison showed a notably higher scores in favor for the study group (p < 0.05) except for the (DF-E) test (p > 0.05).ConclusionTibial nerve flossing is an effective adjunct to conventional therapy in improving foot pain, ankle ROM, and tibial nerve conduction in individuals with TTS.

Preventive effect of the neurodynamic mobilization technique on delayed onset of muscle soreness: a randomized, single-blinded, placebo-controlled study

BACKGROUND

The neurodynamic mobilization (NM) technique is an intervention designed to restore homeostasis by mobilizing the nervous system and its surrounding structures. NM, through its physiological and biomechanical mechanisms, may play a role in modulating delayed Onset Muscle Soreness (DOMS) symptoms and regulating the emerging inflammatory response. The aim of this study was to determine the preventive effects of the NM technique on DOMS.

METHODS

Thirty-four untrained males were randomized into the NM (n = 17) or placebo NM (n = 17) group. Femoral nerve NM and placebo NM techniques were performed for three weeks in both groups. All the participants subsequently performed 300 maximal isokinetic eccentric contractions of the dominant knee extensors. Markers of muscle damage (creatine kinase, lactate dehydrogenase) and inflammation (IL-6, TNF-α), as well as muscle soreness, pressure pain threshold (PPT) and muscle function, were measured at baseline; immediately before (pre) and after (0 h) the completion of the exercise-induced muscle damage (EIMD) protocol; and at 24, 48, and 72 h.

RESULTS

Following the EIMD protocol, muscle soreness peaked at 24 h, while PPT reached its lowest level. The NM group exhibited significantly lower muscle soreness scores (F3.160 = 5.436, p = 0.001) and higher PPT values (F3.160 = 12.580, p < 0.001) compared to the placebo NM group at 0, 24, 48, and 72 h. Muscle function scores reached their lowest point at 0 h, with the NM group demonstrating significantly higher function scores than the placebo NM group both before the EIMD protocol and at 0 h (F3.160 = 8.532, p < 0.001). IL-6 levels peaked at 0 h, with the placebo NM group showing significantly higher IL-6 values compared to the NM group only at the 0 h time point (F5.160 = 5.377, p < 0.001). No significant group × time interaction effects were observed for the other variables (p > 0.05).

CONCLUSIONS

Three weeks of femoral nerve NM applied to healthy untrained participants had positive effects on the possible negative consequences of DOMS. NM may help alleviate inflammation and muscle damage symptoms and shorten the overall recovery time following DOMS.

Non-pharmacological and non-surgical treatments for low back pain in adults: an overview of Cochrane reviews

BACKGROUND

Low back pain (LBP) is a significant public health issue due to its high prevalence and associated disability burden. Clinical practice guidelines recommend non-pharmacological/non-surgical interventions for managing pain and function in people with LBP.

OBJECTIVES

To provide accessible, high-quality evidence on the effects of non-pharmacological and non-surgical interventions for people with LBP and to highlight areas of remaining uncertainty and gaps in the evidence regarding the effects of these interventions for people with LBP.

METHODS

We searched the Cochrane Database of Systematic Reviews from inception to 15 April 2023, to identify Cochrane reviews of randomised controlled trials testing the effect of non-pharmacological/non-surgical interventions, unrestricted by language. Major outcomes were pain intensity, function and safety. Two authors independently assessed eligibility, extracted data and assessed the quality of the reviews using AMSTAR 2 (A MeaSurement Tool to Assess Systematic Reviews) and the certainty of the evidence using GRADE. The primary comparison was placebo/sham.

MAIN RESULTS

We included 31 Cochrane reviews of 644 trials that randomised 97,183 adults with LBP. We have high confidence in the findings of 19 reviews, moderate confidence in the findings of two reviews, and low confidence in the findings of 10 reviews. We present results for non-pharmacological/non-surgical interventions compared to placebo/sham or no treatment/usual care at short-term (≤ three months) follow-up. Placebo/sham comparisons Acute/subacute LBP Compared to placebo, there is probably no difference in function (at one-week follow-up) for spinal manipulation (standardised mean difference (SMD) -0.08, 95% confidence interval (CI) -0.37 to 0.21; 2 trials, 205 participants; moderate-certainty evidence). Data for safety were reported only for heated back wrap. Compared to placebo, heated back wrap may result in skin pinkness (6/128 participants versus 1/130; 2 trials; low-certainty evidence). Chronic LBP Compared to sham acupuncture, acupuncture probably provides a small improvement in function (SMD -0.38, 95% CI -0.69 to -0.07; 3 trials, 957 participants; moderate-certainty evidence). Compared to sham traction, there is probably no difference in pain intensity for traction (0 to 100 scale, mean difference (MD) -4, 95% CI -17.7 to 9.7; 1 trial, 60 participants; moderate-certainty evidence). Data for safety were reported only for acupuncture. There may be no difference between acupuncture and sham acupuncture for safety outcomes (risk ratio (RR) 0.68, 95% CI 0.42 to 1.10; I2 = 0%; 4 trials, 465 participants; low-certainty evidence). No treatment/usual care comparisons Acute/subacute LBP Compared to advice to rest, advice to stay active probably provides a small reduction in pain intensity (SMD -0.22, 95% CI -0.02 to -0.41; 2 trials, 401 participants; moderate-certainty evidence). Compared to advice to rest, advice to stay active probably provides a small improvement in function (SMD -0.29, 95% CI -0.09 to -0.49; 2 trials, 400 participants; moderate-certainty evidence). Data for safety were reported only for massage. There may be no difference between massage and usual care for safety (risk difference 0, 95% CI -0.07 to 0.07; 1 trial, 51 participants; low-certainty evidence). Chronic LBP Compared to no treatment, acupuncture probably provides a medium reduction in pain intensity (0 to 100 scale, mean difference (MD) -10.1, 95% CI -16.8 to -3.4; 3 trials, 144 participants; moderate-certainty evidence), and a small improvement in function (SMD -0.39, 95% CI -0.72 to -0.06; 3 trials, 144 participants; moderate-certainty evidence). Compared to usual care, acupuncture probably provides a small improvement in function (MD 9.4, 95% CI 6.15 to 12.65; 1 trial, 734 participants; moderate-certainty evidence). Compared to no treatment/usual care, exercise therapies probably provide a small to medium reduction in pain intensity (0 to 100 scale, MD -15.2, 95% CI -18.3 to -12.2; 35 trials, 2746 participants; moderate-certainty evidence), and probably provide a small improvement in function (0 to 100 scale, MD -6.8, 95% CI -8.3 to -5.3; 38 trials, 2942 participants; moderate-certainty evidence). Compared to usual care, multidisciplinary therapies probably provide a medium reduction in pain intensity (SMD -0.55, 95% CI -0.83 to -0.28; 9 trials, 879 participants; moderate-certainty evidence), and probably provide a small improvement in function (SMD -0.41, 95% CI -0.62 to -0.19; 9 trials, 939 participants; moderate-certainty evidence). Compared to no treatment, psychological therapies using operant approaches probably provide a small reduction in pain intensity (SMD -0.43, 95% CI -0.75 to -0.11; 3 trials, 153 participants; moderate-certainty evidence). Compared to usual care, psychological therapies (including progressive muscle relaxation and behavioural approaches) probably provide a small reduction in pain intensity (0 to 100 scale, MD -5.18, 95% CI -9.79 to -0.57; 2 trials, 330 participants; moderate-certainty evidence), but there is probably no difference in function (SMD -0.2, 95% CI -0.41 to 0.02; 2 trials, 330 participants; moderate-certainty evidence). It is uncertain whether there is a difference between non-pharmacological/non-surgical interventions and no treatment/usual care for safety (very low-certainty evidence).

AUTHORS' CONCLUSIONS

Spinal manipulation probably makes no difference to function compared to placebo for people with acute/subacute LBP. Acupuncture probably improves function slightly for people with chronic LBP, compared to sham acupuncture. There is probably no difference between traction and sham traction for pain intensity in people with chronic LBP. Compared to advice to rest, advice to stay active probably reduces pain intensity slightly and improves function slightly for people with acute LBP. Acupuncture probably reduces pain intensity, and improves function slightly for people with chronic LBP, compared to no treatment. Acupuncture probably improves function slightly for people with chronic LBP, compared to usual care. Exercise therapies probably reduce pain intensity, and improve function slightly for people with chronic LBP, compared to no treatment/usual care. Multidisciplinary therapies probably reduce pain intensity, and improve function slightly for people with chronic LBP, compared to usual care. Compared to usual care, psychological therapies probably reduce pain intensity slightly, but probably make no difference to function for people with chronic LBP.

Comparison of different treatment positions of nerve slider technique for patients with low back pain: a randomized control trial

BACKGROUND

Low back pain (LBP) accompanied by sciatica is a widespread musculoskeletal issue with multifactorial etiology, impacting individuals across various demographics. Conservative treatments, notably physiotherapy, are key in managing LBP with sciatica, with neural mobilization techniques emerging as beneficial adjuncts.

AIM

This research aims to assess the effectiveness of utilizing the sciatic slider technique (SST) in both supine and slump positions, compared to conventional physiotherapy alone, in alleviating pain severity, improving lumbar flexibility, lumbar lordosis, lower limb muscle strength, and functional ability in patients with LBP associated with sciatica.

DESIGN

randomized controlled trial.

SETTING

Department of Physiotherapy at Alia Hospital.

POPULATION

Sixty participants with LBP associated with sciatica.

METHODS

The participants were randomly allocated into three groups: Group (A) N.=20 received the SST in a slump position alongside conventional physiotherapy, Group (B) N.=20 received the same technique in a supine position with conventional physiotherapy, and Group (C) or (control) N.=20 underwent only conventional physiotherapy. Each group underwent three sessions per week for four weeks. Outcome measures included pain intensity (Numerical Pain Rating Scale), functional disability (Oswestry Disability Index), lumbar flexibility (Modified Schober test), lower limb muscle strength (Hand-held dynamometry), and lumbar lordosis (Flexible ruler).

RESULTS

Analysis revealed significant differences between treatment groups. The slump position exhibited superior effectiveness in reducing pain intensity (P<0.001), and improving disability (P<0.001), with greater improvements in pain scores and disability index percentages. Additionally, slump position therapy led to significantly greater enhancements in range of motion (P<0.001), and hip abductor (P=0.007) when compared to the supine position. However, both techniques showed similar effects on lumbar lordosis angle and various lower limb muscle strength.

CONCLUSIONS

The sciatic nerve slider technique, whether applied in the slump or supine position, demonstrated superior outcomes compared to conventional physiotherapy alone in managing LBP with sciatica. Nevertheless, the slump position showed greater efficacy in reducing pain, improving disability, and enhancing certain functional parameters.

CLINICAL REHABILITATION IMPACT

These findings advocate for the inclusion of neural mobilization techniques, particularly in the slump position, in the management of LBP with sciatica.

Neurodynamic testing of the suprascapular nerve: An observational cadaveric study

BACKGROUND

Suprascapular neurodynamic tests are used to clinically test for suprascapular nerve mechanosensitivity. Various tests described in the literature are proposed to induce suprascapular nerve mechanical strain but their potential effects on nerve strain have not been established.

METHODS

This observational cadaveric study used biomechanical measurements to evaluate and compare the strain undergone by the suprascapular nerve during five different neurodynamic positions: (1) Cervical contralateral rotation and scapular retraction; (2) Cervical contralateral sidebending + shoulder girdle depression; (3) Shoulder girdle depression, retraction, posterior tilt and downward rotation; (4) Position 3 + contralateral cervical sidebending; and (5) Scapular protraction + Cervical contralateral sidebending (protraction sidebending test). Suprascapular nerve strains were measured using two differential transducers, one placed before the nerve entry by the suprascapular notch (prescapular portion) and the second after the spine of the scapula in the infraspinal fossa (scapular portion).

FINDINGS

Prescapular portion: all 5 positions induced a mean strain increase of 22.70 % (95 %CI 17.14, 28.26) with no significant differences between positions (p > 0.05). Scapular portion: the protraction sidebending test provoked the highest strain increase of 8.99 % (95 %CI 6.83, 11.15), significantly greater than the other positions (p < 0.05).

INTERPRETATION

All 5 positions increased suprascapular nerve strain of the prescapular portion of the suprascapular nerve. The protraction sidebending test induced the highest strain of the scapular portion of the nerve. As it is likely to influence both portions of the suprascapular nerve, the protraction sidebending test is the most suitable neurodynamic test to test for suprascapular heightened mechanosensitivity.

The effects of Neurodynamic Mobilization exercises on upper extremity pain, muscle strength, and functions in patients with multiple sclerosis: A randomised controlled, single blinded study

BACKROUND

Manual therapy techniques are available for pain management in Multiple Sclerosis (MS); however, the results of neurodynamic mobilization (NM) are not known. The aim of this study was to investigate the effects of NM exercises on pain, muscle strength and upper extremity functions in MS patients.

METHODS

Patients aged between 18 and 65 years diagnosed with Relapsing Remitting (RR) MS (n = 31) according to McDonald 2010 diagnostic criteria were included in the study. Patients were divided into the NM group (bilateral upper extremity NM and strengthening exercises) (n = 15) and the control group (bilateral strengthening exercises) (n = 16) by simple randomization. Visual Analog Scale (VAS) (most severe and average score) was used to assess pain intensity, and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) questionnaire was used to assess pain character. Muscle strength was evaluated with the digital muscle strength measurement device (Kforce Kinvent), manual skills were evaluated with the Nine Hole Peg Test (NHPT) and Manual Ability Measure-36 (MAM-36). Measurements were obtained from the most affected side, unilateral.

RESULTS

The mean of the most severe score of VAS (p < 0.001), the average score of VAS (p < 0.001), and the LANSS in both groups (p < 0.05) decreased significantly. Shoulder flexor muscle strength was increased significantly in both groups (p < 0.05). Shoulder extensors, elbow flexors, and elbow extensors was increased significantly in NM group (p < 0.05). MAM-36 scores was increased significanty in both groups (p < 0.05). NHPT scores showed significant decrease in the NM group (p < 0.05). There was no significant difference between the groups in terms of VAS, LANSS, muscle strength, MAM-36 and NHPT (p > 0.05).

CONCLUSION

It was found that NM exercises added to upper extremity strengthening therapy in patients with MS reduced pain, increased muscle strength of shoulder extensors, elbow flexors, and elbow extensors, and improved manual dexterity. However, although positive effects were observed when NM exercises were added to the strengthening exercises, the results were found to be similar in these groups.

Assessment of the ulnar nerve stiffness during valgus stress of the elbow using shear wave elastography: an observational cross-sectional study

BACKGROUND

Identification of the relationship between valgus stress in the medial elbow and ulnar nerve strain during maximum external rotation of the shoulder is pivotal for the prevention and management of ulnar neuropathies. In this observational cross-sectional study, we aimed to determine the changes in ulnar nerve stiffness under valgus stress at different nerve entrapment sites.

METHODS

Twenty healthy baseball players participated in the study. The stiffness of the ulnar nerve on the throwing side was assessed at two sites, the arcade of Struthers and the Osborne's ligament, at 0°, 60°, and 90° flexion by shear wave elastography using a 10-MHz linear transducer. The arcade of Struthers was defined as the proximal site and the Osborne's ligament as the distal site. Valgus stress was applied to the medial elbow at 0, 30, 50, and 70 N using a Telos stress device, and the stiffness caused by valgus stress was measured.

RESULTS

At all elbow flexion angles, the stiffness of the ulnar nerve under 70 N valgus stress was higher than that under 30 N stress. The stiffness of the ulnar nerve at the proximal site was significantly higher than that at the distal site.

CONCLUSION

Valgus stress increases ulnar nerve stiffness. In addition, the stiffness of the proximal site increases.

Accuracy of the Standard and Distal-to-Proximal Sequence of the Upper Limb Neurodynamic Test 1 for the Diagnosis of Carpal Tunnel Syndrome: The Role of Side-to-Side Comparisons

Background/Objective: This study aimed to evaluate the diagnostic accuracy of two upper limb neurodynamic test 1 (ULNT1) sequences for detecting carpal tunnel syndrome (CTS) in patients with unilateral symptoms. The standard sequence (ULNT1-STD) and a distal-to-proximal sequence (ULNT1-DIST) were investigated. A local-initiated sequence may facilitate symptoms reproduction in CTS, and comparing the affected side with the unaffected side could improve the detection of altered median nerve mechanosensitivity when symptoms are not directly reproduced. Methods: A total of 134 consecutive patients with clinically suspected unilateral CTS were recruited. Nerve conduction studies were used as a reference test. Results: When considering only symptom reproduction as the criterion for a positive test, ULNT1-STD showed a sensitivity of 0.398 and a specificity of 0.780 (positive likelihood ratio [+LR]: 1.81; negative likelihood ratio [-LR]: 0.77); whereas ULNT1-DIST demonstrated a sensitivity of 0.548 with a specificity of 0.732 (+LR: 2.04; -LR: 0.62). When a positive test was defined by symptom reproduction or inter-limb asymmetry (in range of motion or sensory response), ULNT1-STD showed an improved sensitivity of 0.613 but a reduced specificity of 0.537 (+LR: 1.32; -LR: 0.72). In comparison, ULNT1-DIST increased its sensitivity to 0.871 with a specificity of 0.683 (+LR: 2.75; -LR: 0.19). Conclusions: ULNT1-DIST offers better diagnostic accuracy for CTS compared to the ULNT1-STD sequence, especially when interlimb asymmetries in range of motion or sensory response are considered. However, side-to-side comparisons have reduced utility in cases with bilateral symptoms, limiting their application in clinical practice.

Effect of cervical contralateral lateral flexion on the median nerve and fascia at the wrist - Cadaveric study

BACKGROUND

Neurodynamic tests are an essential aspect of the physical examination of the patient when suspicion of neural involvement exists. A manoeuvre that is hypothesised to move nerves differentially relative to other structures (structural differentiation) has been proposed as a necessary part of neurodynamic testing for differential diagnosis. However, although the specificity of structural differentiation for peripheral nerve over muscle has been demonstrated in some body regions, no study has tested specificity of nerve movement relative to fascia.

OBJECTIVES

The aim of this study was to measure the effect of the cervical contralateral lateral flexion (CCLF) as an structural differentiation manoeuvre for the median nerve compared to fascia (superficial and deep) at the wrist during the upper limb neurodynamic test 1 (ULNT1).

DESIGN

A cross-sectional study was performed in 5 fresh frozen cadavers.

METHODS

Excursion and strain in the fascia (superficial and deep) and the median nerve were measured at the wrist with structural differentiation during the ULNT1. KINOVEA software was used to measure kinematic parameters.

RESULTS

CCLF resulted in significant proximal excursion in the median nerve (p < 0.001*) but not in the strain. CCLF neither produced changes in strain nor excursion in the superficial and deep fascia (p > 0.05).

CONCLUSION

This study showed that CCLF produced significant differential excursion in the median nerve at the wrist compared to the local superficial and deep fascia during the ULNT1. The data support CCLF in mechanical differentiation between nerve and fascia in this area in diagnosis of local sources of wrist pain.

More Than Just Another Elbow Tendinopathy: A Case Series of Misdiagnosed Ulnar Nerve Compression and Review of Common Upper Extremity Misdiagnoses in Climbing

ABSTRACT

Climbing is an increasingly popular sport. Yet, we have encountered numerous misdiagnosed climbing injuries, highlighting a gap in climbing-related literature and a need for heightened awareness within the sports medicine community. We present a case series that highlights the clinical manifestation of ulnar nerve entrapment and compression in three patients with initially misdiagnosed and mismanaged elbow tendinopathy. After a correct diagnosis of ulnar nerve pathology was made, each patient underwent a prescribed rehabilitation protocol that focused on nerve motility exercises (tensioning and flossing), resulting in a significant reduction in pain and a successful return to their pre-injury climbing performance. We thus aim to raise awareness of this often-mistreated presentation. Furthermore, we highlight other common upper extremity climbing misdiagnoses and provide relevant clinical recommendations to accurately identify and manage such injuries in climbers.

Comparative Effects of Neurodynamic Slider and Tensioner Mobilization Techniques on Sympathetic Nervous System Function: A Randomized Controlled Trial

Objective: To investigate the effect of slider and tensioner neurodynamic techniques (NDTs) on the sympathetic nervous system (SNS) activity, aiming to identify which technique more effectively modulates autonomic responses in asymptomatic individuals. Materials and Methods: In this double-blind controlled trial, a total of 90 healthy participants were randomly allocated into three groups: slider, tensioner, and control. Skin conductance (SC) was continuously monitored throughout the entire 20 min experiment, while body temperature and blood pressure were measured pre- and post-intervention. Results: The SC levels significantly increased in both the slider and tensioner groups compared to the control group during the intervention and end rest period on the left leg (slider vs. control: p < 0.001, d = 1.20; tensioner vs. control: p < 0.001, d = 1.64) and on the right leg (slider vs. control: p < 0.001, d = 1.47; tensioner vs. control: p < 0.001, d = 0.73). There were no significant differences between the two NDTs on the left (p < 0.13, d = 0.89) and right legs (p < 1.00, d = 0.36). The body temperature of the slider group showed a significant increase compared to both the control group (p < 0.001, d = 0.95) and the tensioner group (p < 0.001, d = 1.48). There were no significant differences between the groups in systolic (p = 0.95) or diastolic blood pressure (p = 0.06). There were no side-specific effects on SNS activity between the left and right legs (p < 0.019) during all intervention phases. Conclusions: Significant sympathoexcitatory responses were elicited by both slider and tensioner NDTs in asymptomatic participants, demonstrating their efficacy in modulating the SNS. The differences between the two techniques were not statistically significant; however, the tensioner NDT showed a slightly more pronounced effect, suggesting that the tensioner NDT can be considered superior in terms of overall SNS effect. These findings indicate that both techniques may have the potential to enhance autonomic regulation in clinical practice; however, the tensioner NDT may be more effective. The consistent responses across participants highlight the systemic benefits of NDTs, providing a foundation for further research into their application in symptomatic populations. This study contributes to evidence-based practice by providing baseline data that support the development of theoretical frameworks and aid in clinical decision-making.

Rethinking neck-related arm pain: hypothetical clinical scenarios to differentiate the underlying IASP-defined pain mechanisms

Neck-related arm pain is frequently encountered in clinical settings, yet its underlying pain mechanisms remain elusive. While such pain radiating from the neck to the arm is often attributed to injuries or diseases of the nervous system (neuropathic pain), it can also arise from nociceptive (referred) or nociplastic sources. Regrettably, patients exhibiting this specific pain distribution are frequently diagnosed with varying terms, including 'cervicobrachialgia', 'cervicobrachial neuralgia', 'cervicobrachial pain syndrome', and 'cervical radiculopathy'. The ambiguity surrounding these diagnostic labels complicates the clinical reasoning process. It is imperative for clinicians to discern and comprehend the dominant pain mechanism. Three distinct hypothetical clinical scenarios depict patients with almost identical pain distribution but divergent dominant pain mechanisms. Within these scenarios, both subjective and objective examinations are employed to elucidate the dominant pain mechanism associated with neck-related arm pain: nociceptive, neuropathic, and nociplastic. Furthermore, clinicians must remain aware that the dominant pain mechanism can evolve over time.

Physical therapy in addition to occlusal splint in myogenic temporomandibular disorders: A randomised controlled trial

BACKGROUND

Myogenic temporomandibular disorders (M-TMD) commonly involve occlusal splint (OS) therapy and musculoskeletal physiotherapy (MPT).

OBJECTIVES

To compare the effects of combining OS with MPT and education (EG) against OS and education (CG), in chronic M-TMD patients.

METHODS

In this double-blind randomised controlled trial, 62 participants were assigned to either EG or CG. The primary outcomes, pain levels at rest (VAS rest), maximum oral opening (VAS open) and during chewing (VAS chew), were measured by Visual Analogue Scale (VAS) in cm. The secondary outcome was the range of motion (ROM) for maximum oral opening. Both interventions lasted 3 months, with outcomes assessed at baseline (T0), post-treatment (T1) and 3 months post-treatment (T2).

RESULTS

Intention-to-treat analysis revealed significant improvements favouring EG (VAS rest = -1.50 cm [CI95%: -2.67, -0.32], p = .04; VAS open = -2.00 cm [CI95%: -3.23, -0.75], p < .01; VAS chew = -1.71 cm [CI95%: -2.90, -0.52], p = .01; ROM = 4.61 [CI95%: 0.93, 8.30], p = .04). Additionally, VAS measures were influenced by follow-up times (VAS rest = -0.73 cm [CI95%: -1.30, -0.17], p = 0.03; VAS open = -0.97 cm [CI95%: -1.57, -0.37], p < .01; VAS chew = -1.15 cm [CI95%: -1.73, -0.58], p < .01). At T1, EG demonstrated higher number of responders compared to CG for VAS open (χ2(1) = 4.39, p = .04) and VAS chew (χ2(1) = 11.58, p < .01).

CONCLUSION

Adding MPT to education and OS yields better outcomes in terms of pain reduction and ROM improvement, in chronic M-TMD.

Mechanisms of neurodynamic treatments (MONET): a protocol for a mechanistic, randomised, single-blind controlled trial in patients with carpal tunnel syndrome

BACKGROUND

Physiotherapeutic management is the first-line intervention for patients with entrapment neuropathies such as carpal tunnel syndrome (CTS). As part of physiotherapy, neurodynamic interventions are often used to treat people with peripheral nerve involvement, but their mechanisms of action are yet to be fully understood. The MONET (mechanisms of neurodynamic treatment) study aims to investigate the mechanisms of action of neurodynamic exercise intervention on nerve structure, and function.

METHODS

This mechanistic, randomised, single-blind, controlled trial will include 78 people with electrodiagnostically confirmed mild or moderate CTS and 30 healthy participants (N = 108). Patients will be randomly assigned into (1) a 6-week progressive home-based neurodynamic exercise intervention (n = 26), (2) a steroid injection (= 26), or (3) advice (n = 26) group. The primary outcome measure is fractional anisotropy of the median nerve at the wrist using advanced magnetic resonance neuroimaging. Secondary outcome measures include neuroimaging markers at the wrist, quantitative sensory testing, electrodiagnostics, and patient reported outcome measures. Exploratory outcomes include neuroimaging markers at the cervical spine, inflammatory and axonal integrity markers in serial blood samples and biopsies of median nerve innervated skin. We will evaluate outcome measures at baseline and at the end of the 6-week intervention period. We will repeat questionnaires at 6-months. Two-way repeated measures ANCOVAs, followed by posthoc testing will be performed to identify differences in outcome measures among groups and over time.

DISCUSSION

This study will advance our understanding of the mechanisms of action underpinning neurodynamic exercises, which will ultimately help clinicians to better target these treatments to those patients who may benefit from them. The inclusion of a positive control group (steroid injection) and a negative control group (advice) will strengthen the interpretation of our results.

Neurofascialvascular training for carpal tunnel syndrome as an evolution of neurodynamic treatment: A case report

INTRODUCTION

In this case report a new approach called neurofascialvascular training (NFVT) is described. NFVT consists of two mechanisms which improve mechanosensitivity in carpal tunnel syndrome (CTS). The first involves increased blood flow in the nerve microcirculation, while the second stimulates the reciprocal sliding between the thin sheets of connective tissue inside the nerve. The goal of these two actions is to squeeze, mobilize and reduce intraneural edema. The novelty of this approach is the simultaneous involvement of multiple physiological systems to reduce nerve mechanosensitivity. This case report describes the rehabilitation progress achieved by NFVT in a patient with CTS.

MAIN SYMPTOMS AND/OR IMPORTANT CLINICAL FINDINGS

A 64-year-old woman complaining of nocturnal pain and tingling with severe impairment of sleep quality for two years was diagnosed at CTS.

THERAPEUTIC INTERVENTIONS

The patient underwent nine 30-min exercise sessions of NFVT.

OUTCOMES

At each session and at the last follow-up 3 months after the end of treatment the following tests were performed: the upper limb neurodynamic test1 (ULNT1), the Hand Grip Meter and the Phdurkan test. Furthermore ultrasound, numerical rating scale and the Boston Carpal Tunnel Questionnaire (BCTQ) were also adopted.

CONCLUSION

NFVT can improve symptoms and motor dysfunction in a patient with CTS.

TAKE-AWAY LESSON

In the presence of mild carpal tunnel syndrome, active neurofascialvascular training that increases peripheral blood flow and targets fascial tissue within the peripheral nervous system can resolve symptoms and produce significant improvement within a few months of starting treatment.

Exploring Symptom Responses to Upper Limb Neural Test Variations of the Radial Nerve in Patients With Lateral Epicondylalgia: An Observational Study

OBJECTIVE

Clinical practice guidelines recommend the radial nerve mechanosensitivity evaluation in patients with lateral epicondylalgia. Despite different positions and sequences having been described, no research analyzed how each variation triggers symptoms associated with lateral epicondylalgia. The aim of this study was to explore the effects of different positions and sequences in the upper limb neural tension test 2b (ULNT2b) in symptom responses in patients with lateral epicondylalgia.

METHODS

In this observational study, 66 patients underwent 4 test conditions: standard ULNT2b, ULNT2b proximal to distal, ULNT2B with resisted supination, and resisted supination isolated. Paresthesia sensations, symptom reproduction, pain intensity (measured using a visual analog scale), and distribution of painful symptoms data were collected.

RESULTS

Significant differences in paresthesia sensations were observed between groups, with significant differences between the standard ULNT2B and other ULNT variations or resisted supination maneuvers. Symptom reproduction also differed significantly across groups, with significant differences between the standard ULNT2B and other ULNT or resisted supination tests. The positive/negative test and percentage of distribution of painful symptoms scores varied significantly across 4 conditions in both lateral and frontal views. Although pain intensity scores during tests were comparable among the tests, distribution of painful symptoms differed significantly.

CONCLUSION

Variations in the ULNT2b test can affect symptom responses in patients with lateral epicondylalgia. The standard ULNT2b test appears more effective at reproducing symptoms, intensity of paresthesia, and distribution of painful symptoms compared to other ULNT variations and the resisted supination test.

IMPACT

ULNT2b sequences have been shown to elicit varying responses concerning paresthesia, replication of familiar symptoms, positive/negative test results, and distribution of painful symptoms. Clinicians should consider specific test variations during the patients' radial nerve mechanosensitivity assessment to identify aggravating factors reproducing recognizable symptoms. A control group of asymptomatic participants and the role of presence of other comorbidities, psychological factors, or the duration of symptoms were not considered in this study and might play an important role influencing the results of the tests.

Efficacy of neural mobilization and Maitland accessory mobilization in patients with tennis elbow- randomized controlled trial

OBJECTIVE

The objective of the study was to evaluate the efficacy of Maitland accessory mobilization and neural mobilization in patients with tennis elbow.

METHOD

Twenty-five patients meeting the selection criteria were randomly assigned to three experimental groups: Group C (conventional treatment), Group B (neural mobilization), and Group A (Maitland mobilization). Quality of life was assessed using the Patient Rated Tennis Elbow Evaluation (PRTEE), while pain, range of motion, and grip strength were evaluated using the Visual Analog Scale (VAS), a universal goniometer, and a handheld dynamometer. The interventions were administered three times per week for four weeks to the respective groups.

RESULTS

Non-parametric tests were employed to analyze the results due to the non-normal distribution of the data (p < 0.05). Both the Wilcoxon signed-rank test and the Kruskal-Wallis test were utilized to assess differences within and between groups. The results of the between-group analysis demonstrated significant differences in pain (p = 0.018) and quality of life (p = 0.045) among the three groups.

CONCLUSION

After a 4-week intervention, all three groups exhibited notable improvements in discomfort levels, grip strength, and quality of life. Notably, Group B demonstrated the most substantial increase in range of motion (ROM) compared to Groups A and C. Consequently, incorporating neural mobilization into the treatment plan is recommended for patients experiencing Tennis Elbow.

Effectiveness of neural mobilisation for the treatment of nerve-related cervicobrachial pain: a systematic review with subgroup meta-analysis

ABSTRACT

Neural mobilisations (NM) have been advocated for the treatment of nerve-related cervicobrachial pain; however, it is unclear what types of patients with nerve-related cervicobrachial pain (if any) may benefit. Medline, Web of Science, Scopus, PeDro, Cinahl, and Cochrane databases were searched from inception until December 2022. Randomised controlled trials were included if they assessed the effectiveness of NM in nerve-related cervicobrachial pain, and outcome measures were pain intensity and/or disability. Studies were classified according to their inclusion/exclusion criteria as radiculopathy , Wainner cluster , Hall , and Elvey cluster or other . Meta-analyses with subgroup analyses were performed. Risk of bias was assessed using Cochrane Rob2 tool. Twenty-seven studies were included. For pain and disability reduction, NM was found to be more effective than no treatment (pooled pain mean difference [MD] = -2.81, 95% confidence interval [CI] = -3.81 to -1.81; pooled disability standardized mean difference = -1.55, 95% CI = -2.72 to -0.37), increased the effectiveness of standard physiotherapy as an adjuvant when compared with standard physiotherapy alone (pooled pain MD = -1.44, 95% CI = -1.98 to -0.89; pooled disability MD = -11.07, 95% CI = -16.38 to -5.75) but was no more effective than cervical traction (pooled pain MD = -0.33, 95% CI = -1.35 to 0.68; pooled disability MD = -10.09, 95% CI = -21.89 to 1.81). For disability reduction, NM was found to be more effective than exercise (pooled MD = -18.27, 95% CI = -20.29 to -17.44). In most comparisons, there were significant differences in the effectiveness of NM between the subgroups. Neural mobilisations was consistently more effective than all alternative interventions (no treatment, traction, exercise, and standard physiotherapy alone) in 13 studies classified as Wainner cluster . PROSPERO registration: CRD42022376087.

Impact of the Order of Movement on the Median Nerve Root Function: A Neurophysiological Study with Implications for Neurodynamic Exercise Sequencing

Background: Neurodynamic exercise is a common clinical practice used to restore neural dynamic balance. The order in which movements are performed during these exercises is believed to play a crucial role in their effectiveness. This study aimed to investigate the impact of different sequences of neurodynamic exercise on nerve root function, with a specific focus on the median nerve. Methods: Participants were assigned randomly to three experimental groups, each undergoing a different test sequence: standard, proximal-to-distal, and distal-to-proximal. Dermatomal somatosensory evoked potentials (DSSEPs) were recorded at key levels (C6, C7, C8, and T1). Results: The findings revealed a significant influence of the movement sequence on DSSEP amplitudes. The execution of neurodynamic exercise in the proximal-to-distal sequence was associated with a notable reduction in amplitudes (p < 0.05). Conversely, the distal-to-proximal sequence resulted in increased amplitudes compared to the standard sequence (p < 0.05). Conclusions: This study underscores the importance of carefully considering the order of movements during neurodynamic exercising, particularly when evaluating nerve roots that lack the protective perineurium. The choice of sequence appears to have a substantial impact on nerve function, with implications for optimizing clinical neurodynamic exercise techniques.

Effectiveness of Neural Mobilisation on Pain Intensity, Functional Status, and Physical Performance in Adults with Musculoskeletal Pain - A Systematic Review with Meta-Analysis

OBJECTIVE

To investigate up-to-date evidence of the effectiveness of neural mobilisation techniques compared with any type of comparator in improving pain, function, and physical performance in people with musculoskeletal pain.

DATA SOURCES

The following sources were consulted: PubMed, Web of Science, CENTRAL, CINAHL, Scopus, and PEDro databases; scientific repositories; and clinical trial registers. The last search was performed on 01/06/2023.

METHODS

Two reviewers independently assessed the studies for inclusion. We included randomised, quasi-randomised, and crossover trials on musculoskeletal pain in which at least one group received neural mobilisation (alone or as part of multimodal interventions). Meta-analyses were performed where possible. The RoB 2 and the Grading of Recommendations Assessment, Development and Evaluation tools were used to assess risk of bias and to rate the certainty of evidence, respectively.

RESULTS

Thirty-nine trials were identified. There was a significant effect favouring neural mobilisation for pain and function in people with low back pain, but not for flexibility. For neck pain, there was a significant effect favouring neural mobilisation as part of multimodal interventions for pain, but not for function and range of motion. Regarding other musculoskeletal conditions, it was not possible to conclude whether neural mobilisation is effective in improving pain and function. There was very low confidence for all effect estimates.

CONCLUSIONS

Neural mobilisation as part of multimodal interventions appears to have a positive effect on pain for patients with low back pain and neck pain and on function in people with low back pain. For the other musculoskeletal conditions, results are inconclusive.

Changes in biochemical markers following a spinal manipulation - a systematic review update

OBJECTIVE

The aim of this systematic review was to update the current level of evidence for spinal manipulation in influencing various biochemical markers in healthy and/or symptomatic population.

METHODS

This is a systematic review update. Various databases were searched (inception till May 2023) and fifteen trials (737 participants) that met the inclusion criteria were included in the review. Two authors independently screened, extracted and assessed the risk of bias in included studies. Outcome measure data were synthesized using standard mean differences and meta-analysis for the primary outcome (biochemical markers). The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used for assessing the quality of the body of evidence for each outcome of interest.

RESULTS

There was low-quality evidence that spinal manipulation influenced various biochemical markers (not pooled). There was low-quality evidence of significant difference that spinal manipulation is better (SMD -0.42, 95% CI - 0.74 to -0.1) than control in eliciting changes in cortisol levels immediately after intervention. Low-quality evidence further indicated (not pooled) that spinal manipulation can influence inflammatory markers such as interleukins levels post-intervention. There was also very low-quality evidence that spinal manipulation does not influence substance-P, neurotensin, oxytocin, orexin-A, testosterone and epinephrine/nor-epinephrine.

CONCLUSION

Spinal manipulation may influence inflammatory and cortisol post-intervention. However, the wider prediction intervals in most outcome measures point to the need for future research to clarify and establish the clinical relevance of these changes.

Rhizarthrosis Part I: A Literature Review

Rhizarthrosis (RA), or trapeziometacarpal osteoarthritis, is an arthritic degenerative process that affects the first joint of the thumb. The objective of this work is to provide therapists with an overview of the fundamental issues related to the therapeutic management of trapeziometacarpal joint instability. Prevalent in females, especially post-menopause, and linked to age, RA involves ligament and muscle structures, with causes ranging from hormonal influences to mechanical factors. Understanding the biomechanics, stability, and factors contributing to RA is crucial for effective intervention. This study explores the role of ligaments, muscles, and anatomical variants in thumb joint degeneration, emphasizing the importance of stability and congruence. RA manifests as pain at the base of the thumb, limiting grip strength and hindering everyday tasks. Pain initially occurs during specific movements but can progress to constant discomfort, affecting sleep. Chronic RA leads to joint stiffness, deformities like the "Z thumb," and muscle atrophy, impacting daily functions. Clinical evaluation involves pain assessment, joint mobility examination, and palpation. Diagnostic tests like the grind test and lever test aid in confirming RA. Radiographic examination reveals joint space degeneration and osteophytes and helps classify RA stages using the Eaton-Littler classification. Conservative treatment aims to alleviate pain, reduce joint stress, and enhance function. Orthoses help stabilize the joint. Therapeutic exercises, emphasizing muscle strength and dynamic stability, prove beneficial. Manual therapies like neurodynamic, Kaltenborn, Mulligan, and Maitland techniques target pain reduction and improve joint mechanics. The studies on conservative approaches provide evidence that a multimodal intervention consisting of joint mobilization, neural mobilization, and exercise is beneficial in reducing pain in patients with RA. When conservative therapy fails, surgical intervention is indicated.

Specific Neurodynamic Exercises on Pain and Disability in Old Women with Chronic Mechanical Neck Pain: A Randomized Controlled Trial

Neurodynamic exercise is a specific type of exercise used as a neural treatment that focuses on restoring altered homeostasis in the neuroimmune system by mobilising the nervous system and other structures. A prospective, randomized clinical trial was performed to evaluate the effect of neurodynamic exercises on disability and neck pain in elderly women over four weeks. Participants were randomized into two groups: a neurodynamic (NM) group (n = 28) and a non-specific exercise (NSE) group (n = 28). Inclusion criteria were women over 65 years of age who subjectively admitted to having mechanical neck pain for more than six months. Results showed that specific neurodynamic exercises can improve pain and disability in older women with chronic mechanical neck pain. Improvements were observed in all variables (p < 0.05). Significant between-group differences in favour of the NM group were only found for neck pressure pain thresholds and both tibialis anterior muscles. Larger effect sizes were obtained in favour of the NM group, especially for pain, disability, neck extension and inclination and pressure pain thresholds. Neurodynamic exercises have been shown to be more clinically relevant in disability and neck pain in older women.

Effect of tibial nerve mobilization on balance & gait functions in subjects with subclinical diabetic neuropathy: A randomized clinical trial

Introduction

With advancing age, balance control diminishes as a result of cognitive impairment, decreased muscle strength, and impairment in visual, vestibular, and somatosensory systems. Besides aforesaid factors, the addition of diabetes to all these leads to balance and gait-related issues such as falls and fall-related injuries. Impaired balance and gait performance in diabetics are primarily attributed to the diminished sensory function of the foot and ankle region owing to diabetic neuropathy. The purpose of this study was to explicitly examine the impact of neural mobilization on the balance & gait functions of subjects having subclinical diabetic neuropathy.

Methods

40 individuals with subclinical diabetic neuropathy, ranging in age from 50 to 75 years, were assigned to two groups at random: Group 1 received the concurrent application of Tibial nerve mobilization and Balance-Gait training whereas Group 2 received only Balance-Gait training. The therapy was administered five times each week, for four weeks. On the first and last day of treatment, measurements of VPT, BBS, TUG, and DGI were taken from each subject.

Results

The results of the study found that post neural mobilization and Balance-Gait training, scores of VPT, BBS, DGI, and TUG showed improvement but it was not significant. As it is evident that diabetic neuropathy is progressive in nature, even small changes can be helpful.

Conclusion

Neural mobilization integrated with balance-gait training of subclinical diabetic neuropathic individuals resulted in improved sensory functions along with enhanced balance-gait functions.

Upper limb neurodynamic mobilization disperses intraneural fluid in cervical nerve roots: A human cadaveric investigation

BACKGROUND

Cervical radiculopathy is a common cause of neck pain with resultant intraneural edema and impaired nerve function. One strategy to treat radiculopathy is neurodynamic mobilization (NDM); however, little is known about the effect of this treatment on nerve tissue fluid dynamics.

OBJECTIVE

Investigate the impact of upper limb, median nerve-biased NDM on longitudinal intraneural fluid dispersion in the C5,C6,C7 nerve roots in un-embalmed cadavers.

DESIGN

In situ repeated measures.

METHODS

Human cadavers (n = 8) were dissected to expose and inject C5,C6,C7 cervical nerve roots with a dying agent. Initial longitudinal dye spread was recorded after dye spread stabilization. Cadavers were taken through 150 repetitions of upper limb, median nerve-biased NDM followed by dye spread re-measurement. Paired-samples t-tests with Bonferroni correction (α = 0.017) were used to compare pre-vs post-NDM dye spread measurements at C5,C6,C7 nerve roots; a one-way repeated measures ANOVA (α = 0.05) was used to examine differences between change scores for C5,C6,C7 nerve roots.

RESULTS

Median nerve-biased NDM resulted in significant intraneural longitudinal dye spread at C5 and C6 nerve roots of 0.6 ± 0.6 mm and 3.4 ± 3.9 mm, respectively (p < 0.014). Dye spread was not significant at C7 nerve root (0.4 ± 0.7 mm). There was no between root difference in change of longitudinal dye spread between C5, C6, and C7 nerve roots.

CONCLUSIONS

The results of this study show median nerve-biased NDM produced internal fluid movement within C5 and C6 cervical nerve roots. Results provide insight regarding possible mechanism of action and feasibility of NDM in treatment of patients with cervical radiculopathy.

The effectiveness of neuromobilization exercises in carpal tunnel syndrome: Systematic review and meta-analysis

PURPOSE

To examine the effectiveness of Neuromobilization Exercises (NE) on pain, grip and pinch strength, two-point discrimination, motor and sensory distal latency, symptom severity, and functional status using the Boston Carpal Tunnel Questionnaire (BCTQ) in Carpal Tunnel Syndrome (CTS).

METHODS

Major electronic databases were searched from inception up to September 2021 for randomized trials comparing the effects of NE with or without other interventions against no treatment, surgery, or other interventions in patients with CTS. Standardized Mean Differences (SMD) and 95% confidence interval (CI) were calculated using a random-effects inverse variance model according to the outcome of interest and comparison group. Methodological quality was assessed with PEDro and quality of evidence with the GRADE approach.

RESULTS

Twenty-five articles were included and sixteen of them demonstrated high methodological quality. NE was superior to no treatment on pain (very low-quality evidence; SMD = -2.36, 95% CI -4.31 to -0.41). NE was superior to no treatment on the functional scale of the BCTQ (low-quality evidence; SMD = -1.27 95% CI -1.60 to -0.94). Most importantly, NE did not demonstrate evidence of clinical effectiveness.

CONCLUSION

Low to very low-quality evidence suggests that there are no clinical benefits of NE in patients with mild to moderate CTS.

The sono-elastography evaluation of the immediate effects of neurodynamic mobilization technique on median nerve stiffness in patients with carpal tunnel syndrome

OBJECTIVES

The stiffness of median nerve increases in carpal tunnel syndrome (CTS) even at mild stage of syndrome which could be regarded as a diagnostic criterion. The aim of this study was to evaluate the immediate effects of neurodynamic technique on median nerve stiffness and cross-sectional area (CSA) at wrist and elbow in individuals with CTS.

MATERIAL AND METHODS

It was a quasi-experimental study. Twenty patients were recruited for this study. They were included if aged 18-65 years and diagnosed with CTS based on electrodiagnostic and clinical findings. The exclusion criteria were previous surgeries at wrist or elbow. Patients were assessed by shear wave sono-elastography before and immediately after one session of neurodynamic mobilization technique (NDM). The primary outcome measure was the stiffness of the median nerve at wrist and the secondary outcomes were nerve stiffness at elbow and CSA of nerve at wrist and elbow.

RESULTS

Median nerve stiffness and CSA decreased significantly at wrist immediately after a session of NDM. These parameters also decreased at elbow but were not statistically significant.

CONCLUSION

One session of NDM reduced the stiffness and CSA of median nerve at wrist in patients with CTS as detected by sono-elastography verifying that sono-elastography is able to quickly detect the immediate biomechanical changes of the median nerve.

Effects of Complex Pain Control Programs on Taekwondo Athletes with Recurrent Low Back Pain: A Case Study

Background and Objectives: Practitioners of martial arts such as Taekwondo are likelier to experience back pain during training or competition. As the back pain of taekwondo athletes shows various symptoms depending on the athlete's characteristics, such as technique and movement, a case study was conducted to verify the intervention effect suitable for individual traits. We examined the effects of a complex pain control program on pain, mechanosensitivity, and physical function in a Taekwondo athlete with recurrent low back pain (LBP). Materials and Methods: A Taekwondo athlete with LBP was recruited from D University, Busan. The intervention program was performed for 45 min twice a week for 3 weeks, and the patient was followed up with after 2 weeks. The numerical rating pain scale (NRPS), pain pressure threshold, mechanosensitivity, and Oswestry Disability Index (ODI) scores were measured before and after the intervention. Therapeutic massage and nerve stimulation therapy were performed. Lumbar flexion, extension, and rotation were performed in the movement control exercise group, whereas the sliding technique, a neurodynamic technique of the tibial nerve, was applied in the neurodynamic technique group. This effect was verified by comparing the average measured values before and after the intervention. Results: Pain (NRPS) and mechanosensitivity reduced, range of motion and tactile discrimination abilities improved, and physical function (ODI) improved. The effect of the improved intervention lasted 2 weeks. Conclusions: These results indicate that application of complex pain control programs considering the four aspects of pain mechanisms for 3 weeks can be an effective intervention in Taekwondo athletes with recurrent LBP.

Effectiveness of physiotherapy plus acupuncture compared with physiotherapy alone on pain, disability and grip strength in people with carpal tunnel syndrome: A randomized clinical trial

BACKGROUND

Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome in the upper extremities. Acupuncture is often used as a treatment method in CTS and numerous studies consider it effective. However, no study has yet compared the efficacy of physical therapy including bone and neural mobilization, exercise and electrotherapy with and without acupuncture in CTS patients.

PURPOSE

comparing the effect of physiotherapy plus acupuncture with physiotherapy alone on pain, disability and grip strength in CTS patients.

METHOD

Forty patients with mild to moderate CTS were randomly divided into two equal groups. Both groups received exercise and manual techniques for 10 sessions. Patients in the physiotherapy plus acupuncture group also received 30 min of acupuncture in every session. The visual analog scale (VAS) score, the score on the Boston carpal tunnel questionnaire for functional status and symptom severity, shortened disability of arm, shoulder, hand (Quick-DASH) score and grip strength were evaluated at pre-test and post-test.

RESULTS

According to ANOVA results, there is a significant interaction between group and time for VAS, BCTQ and Quick-DASH parameters. At the post-test, while the parameters of VAS, BCTQ and Quick-DASH in the physiotherapy plus acupuncture group had a statistically significant difference compared to the physiotherapy group, no significant difference was observed between the two groups in the pre-test. Moreover, there is no significant difference between groups in grip strength improvement.

CONCLUSION

This study shows preliminary evidence that physiotherapy plus acupuncture, was more effective than physiotherapy alone in pain relief and improving disability of patients suffering from CTS.

Muscle responses during radial nerve-biased upper limb neurodynamic test in asymptomatic individuals: a cross-sectional study

This laboratory cross-sectional study aimed at explore the muscle response (MR) of the upper trapezius, infraspinatus, biceps brachii and extensor carpi radialis brevis (ECRB) during the radial nerve-biased upper limb neurodynamic test (RN-ULNT) in healthy participants. Myoelectric activity was stage-by-stage recorded during two sequencing variants of the RN-ULNT: S1, in which elbow extension was the last movement; and S2, in which wrist flexion was the last movement. Final elbow and wrist joint angle and sensory response (SR) in five zones (Z1-Z5) were also registered. MR was qualitatively categorized as 'absent' (No-MR), 'true' (TMR) or 'uneven' (UMR). In both sequences, significant increases in muscle activity occurred mostly during shoulder abduction and elbow extension (p ≤ 0.009). Also, elbow extension but not wrist flexion increased the activity of the ECRB muscle (p ≤ 0.009). S2 showed significantly higher upper trapezius (p = 0.04) and biceps brachii (p = 0.036) muscle activity during wrist flexion, and higher report of SR in Z1 and Z4 (p < 0.001) compared to S1. Only the ECRB muscle showed significant differences in the MR type between S1 and S2 (TMR, p = 0.016; UMR, = 0,012). Our results may be useful in the assessment of upper limb musculoskeletal disorders.

The Effectiveness of Neuromobilization in Patients With Cervical Radiculopathy: A Systematic Review With Meta-Analysis

CONTEXT

Neuromobilization exercises (NE) could be a useful therapeutic tool to induce analgesia and increase function and range of motion (ROM) in patients with musculoskeletal pathologies with neuropathic components; however, the effectiveness of this intervention in patients with cervical radiculopathy (CR) is unknown.

OBJECTIVE

To determine the effectiveness of NE in CR on pain, function, and ROM.

DESIGN

Systematic review and meta-analysis.

EVIDENCE ACQUISITION

An electronic search was performed in the MEDLINE, Scopus, PEDro, and EBSCO databases from inception until June 2022. The authors included randomized clinical trials that evaluated the effectiveness of NE against control groups or other interventions that aimed to treat patients with CR.

EVIDENCE SYNTHESIS

Seven clinical trials met the eligibility criteria, and for the quantitative synthesis, 5 studies were included. For the studies that compared NE with a control group, the standardized mean difference for pain was -1.33/10 (95% confidence interval [CI], -1.80 to -0.86; P < .01; I2 = 0%), for function with the Neck Disability Index was -1.21/50 (95% CI, -1.67 to -0.75; P < .01; I2 = 0%), and for neck flexion and extensions was 0.66 (95% CI, 0.23 to 1.10; P < .01; I2 = 0%) and 0.47 (95% CI, 0.04 to 0.90; P < .01; I2 = 0%), respectively, with evidence of clinical effectiveness. These findings were based on moderate-quality evidence according to the Grading of Recommendation, Assessment, Development, and Evaluation rating. In studies that compared NE with other interventions, the meta-analysis failed to demonstrate the statistical or clinical superiority of NE.

CONCLUSIONS

Moderate quality of evidence suggests that NE may be superior to no treatment for pain, function, and ROM in patients with CR. In contrast, NE are not superior to other interventions in the same outcomes, based on low- to very low-quality evidence. More high-quality research is needed to assess the consistency of these results.

Neurodynamics Is an Effective Intervention for Carpal Tunnel Syndrome

Clinical Scenario: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper-extremity. Due to the involvement of the median nerve, long-term compression of this nerve can lead to hand dysfunction and disability that can impact work and daily life. As such, early treatment is warranted to prevent any long-term damage to the median nerve. Conservative management is utilized in those with mild to moderate CTS. Neural mobilizations can aid in the reduction of neural edema, neural mobility, and neural adhesion while improving nerve conduction. Clinical Question: Is neurodynamics effective in reducing pain and reported symptoms in those with CTS? Summary of Key Findings: Four studies were included, with 2 studies utilizing passive neural mobilizations, one study using active techniques, and one study using active neural mobilizations with splinting. All studies showed large effect size for pain, symptom severity, and physical function. Clinical Bottom Line: Neurodynamics is an effective treatment for CTS. Splinting is only effective when combined with neurodynamics. Strength of Recommendation: Level B evidence to support the use of neurodynamics for the treatment of CTS.

Physiotherapy for Piriformis Syndrome Using Sciatic Nerve Mobilization and Piriformis Release

Piriformis syndrome is also synonymous with sciatica or buttock pain. This is a condition where the muscle irritates the sciatic nerve. This nerve passes above, below, or in between the piriformis muscle piercing it. The muscle tightens or shortens, thus compressing the nerve and disturbing the impulses passing from it. The sciatic nerve is a combination of nerve roots from L4 to S3. Piriformis works as a lateral rotator and is a synergistic muscle of the flexor and abductor group. Females most commonly present with piriformis syndrome than males. Many causative factors are responsible for the compression or impingement of the sciatic nerve, one of which is piriformis syndrome. Tingling, numbness, and pain are most often felt by patients when they have compression of any of the nerves. Many physiotherapy techniques have been found to be effective in managing this problem. Techniques like nerve mobilization, stretching, myofascial release, deep friction massage, and many more have been studied by authors describing their effects in the treatment of piriformis syndrome. Neural mobilization consists of two techniques, nerve gliding and nerve tensioning. Studies have found that the gliding technique produces less strain on the nerve than the tensioning technique. Piriformis stretch reduces the tightening, which has caused the impingement. Two techniques have been used for this stretch, stretching with hip flexion over 90 degrees and hip flexion under 90 degrees. This review focuses on the different advances in treating piriformis syndrome.

Effects of Neural Mobilization on Sensory Dysfunction and Peripheral Nerve Degeneration in Rats With Painful Diabetic Neuropathy

OBJECTIVE

This study aims to evaluate the effectiveness of neural mobilization (NM) in the management of sensory dysfunction and nerve degeneration related to experimental painful diabetic neuropathy (PDN).

METHODS

This is a pre-clinical animal study performed in the streptozocin-induced diabetic rat model. Three groups were included: a treatment group of rats with PDN receiving NM under anesthesia (PDN-NM, n = 10), a sham treatment group of rats with PDN that received only anesthesia (PDN-Sham, n = 9), and a vehicle control group with nondiabetic animals (Vehicle, n = 10). Rats in the PDN-NM and PDN-Sham groups received 1 treatment session on days 10, 12, and 14 after streptozocin injection, with a 48-hour rest period between sessions. Behavioral tests were performed using von Frey and Plantar tests. Evaluation for peripheral nerve degeneration was performed through measuring protein gene product 9.5-positive intra-epidermal nerve fiber density in hind-paw skin biopsies. All measurements were performed by a blinded investigator.

RESULTS

The behavioral tests showed that a single NM session could reduce hyperalgesia, which was maintained for 48 hours. The second treatment session further improved this treatment effect, and the third session maintained it. These results suggest that it requires multiple treatment sessions to produce and maintain hypoalgesic effects. Skin biopsy analysis showed that the protein gene product 9.5-positive intra-epidermal nerve fiber density was higher on the experimental side of the PDN-NM group compared with the PDN-Sham group, suggesting NM may mitigate the degeneration of peripheral nerves.

CONCLUSION

This study demonstrated that NM may be an effective method to manage experimentally induced PDN, potentially through mitigation of nerve degeneration. Further studies are needed to develop standardized protocols for clinical use.

IMPACT

These findings provide neurophysiological evidence for the use of NM in PDN and can form the basis for the development of physical therapy-based programs in clinics.

Neurodynamic Exercises in College Athletes With Musculoskeletal Pain: A Critically Appraised Topic

CLINICAL SCENARIO

Pain is a common complaint following an orthopedic injury; however, the exact cause of nociception can be complex. Multiple tissues can generate a patient's complaint of pain, such as the skin, muscle, ligaments, tendon, nerves, and bones. Regarding the somatosensory system, inflammation around the nerve can create pain and alter movement coordination; this information has resulted in increased awareness of neurodynamic assessments and exercises. Neurodynamic assessments and exercises provide a unique paradigm to effectively assess and treat neural tissue, which may not commonly be considered within the traditional orthopedic examination.

CLINICAL QUESTION

In college athletes with musculoskeletal pain and activity impairments, does the use of neurodynamic exercises improve pain or function?

SUMMARY OF KEY FINDINGS

Of the 5 studies, all consisted of chronic injuries with 3 involving upper-extremity pathologies and 2 focusing on lower-extremity pathologies. All 5 studies noted short- and long-term improvement following the incorporation of neurodynamic sliders or tensioners into the treatment plan. Four of the studies had follow-up periods greater than 30 days with sustained improvement on patient outcomes. Only 2 studies described a progression of neurodynamic exercises through sliders and tensioners. Three studies utilized a set/repetition format for exercise prescription, whereas a fourth used a time-based format, and a fifth article utilized both. Finally, 4 studies utilized neurodynamic assessments to identify whether there was a neural component to the patient's presentation (eg, peripheral nerve mechanosensitivity).

CLINICAL BOTTOM LINE

In individuals with musculoskeletal impairments, evidence exists to support the use of neurodynamic exercises, such as sliders and tensioners, to improve pain and pain-related disability when neural sensitivity exists.

STRENGTH OF RECOMMENDATION

Grade C evidence exists to support the use of neurodynamic exercises in college athletes with a musculoskeletal impairment.

Comparison of Two Manual Therapy Programs, including Tendon Gliding Exercises as a Common Adjunct, While Managing the Participants with Chronic Carpal Tunnel Syndrome

Background

Carpal tunnel syndrome (CTS) is the symptomatic compression neuropathy of the median nerve at the wrist level that may become a reason for upper limb disability, in the women and men population.

Objective

This study aimed to compare the efficacy of the neurodynamic technique (NT) and carpal bone mobilization technique (CBMT) incorporated with tendon gliding exercises (TGE) as an effect-enhancing adjunct while managing the participants with chronic CTS.

Methods

The study followed a two-arm parallel-group randomized comparative design. Thirty participants (aged 30–59 years) with chronic CTS were recruited randomly to both the NT and CBMT groups. In addition to the TGE (a common adjunct), NT and CBMT were performed in the NT and CBMT groups, respectively, for three weeks. The primary outcome measures including pain intensity, functional status, grip strength, and motor nerve conduction study were assessed using a visual analogue scale (VAS), Boston Carpal Tunnel Questionnaire (BCTQ), hand-held dynamometer, and electromyograph, respectively, at baseline, 3 weeks postintervention, and follow-up at one week post end of the intervention. Paired and unpaired t-test were used to calculate the differences in intervention effects within and between the groups with keeping the level of significance α at 0.05.

Results

The data analysis revealed a significant (95% CI, p < 0.05) difference for all outcomes within each group compared across different time intervals. Similarly, a significant difference was found for all outcomes except pain and grip strength compared between groups at 3 weeks postintervention and follow-up at one week post end of the intervention.

Conclusions

The NT revealed more effectiveness than the CBMT when incorporated with TGE to improve nerve conduction velocity and functional status of the hand. However, both NT and CBMT were equally effective in improving pain and grip strength while managing the participants with chronic CTS. In addition, the TGE contributed as a beneficial, effect-enhancing adjunct to the NT and CBMT differently. Significance. The study will guide the physiotherapist in applying either of the combination techniques suitable for achieving treatment objectives while managing the participants with chronic CTS.

Effects of Neural Mobilization on Pain Intensity, Disability, and Mechanosensitivity: An Umbrella Review With Meta-Meta-Analysis

OBJECTIVE

The purpose of this study was to assess the current evidence for the effects of neural mobilization (NM) treatments.

METHODS

Three umbrella reviews with meta-meta-analyses were conducted to determine the effects of NM on pain intensity and disability in people with musculoskeletal disorders and on mechanosensitivity in participants who were asymptomatic. The study used the grading criteria proposed by the Physical Activity Guidelines Advisory Committee to assess the quality of evidence.

RESULTS

One meta-meta-analysis revealed a statistically significant moderate effect on pain intensity (standardized mean difference [SMD] = -0.75, 95% CI = -1.12 to -0.38) but with evidence of heterogeneity (Q = 14.13; I2 = 65%). The study found a significantly large effect of NM on disability (SMD = -1.22, 95% CI = -2.19 to -0.26), again with evidence of heterogeneity (Q = 31.57; I2 = 87%). The third meta-meta-analysis showed a statistically significant moderate effect of NM on mechanosensitivity (SMD = 0.96, 95% CI = 0.35 to 1.57), with no evidence of heterogeneity (Q = 2.73; I2 = 63%). For all examined outcomes, the quality of evidence was limited.

CONCLUSION

Overall, the results indicated that although NM treatment had a moderate to large beneficial clinical effect on pain intensity and disability in people with musculoskeletal disorders and on mechanosensitivity in individuals who were asymptomatic, the quality of evidence was limited.

IMPACT

Neural mobilization treatments showed positive results on the pain intensity and disability in individuals with musculoskeletal conditions. Neural mobilization could be integrated into the physical therapy management, although more research is needed.

Comparative effects of tensioning and sliding neural mobilization on peripheral and autonomic nervous system function: A randomized controlled trial

Background

Although different types of neural mobilization (NM) exercises induce different amounts of longitudinal nerve excursion and strain, the question whether the increased longitudinal stress and nerve excursion from sliding or tensioning intervention may subtly affect the neural functions has not been answered yet.

Objective

To compare the effects of tensioning NM versus sliding NM of the median nerve on peripheral and autonomic nervous system function.

Methods

In this randomized controlled trial, 90 participants were randomly assigned to tensioning NM, sliding NM, or sham NM. The neurophysiological outcome measures included peak-to-peak amplitude of the dermatomal somatosensory evoked potential (DSSEP) for dermatomes C6, C7, C8, and T1. Secondary outcome measures included amplitude and latency of skin sympathetic response. All outcome measures were assessed pretreatment, immediately after the two weeks of treatment and one week after the last session of the treatment.

Results

A 2-way repeated measures ANOVA revealed significant differences between the three groups. The post hoc analysis indicated that tensioning NM significantly decreased the dermatomal amplitude for C6, C7, C8, and T1 ( p < 0 . 005 ). Sympathetic skin responses in the gliding NM group showed lower amplitudes and prolonged latencies post-treatment when compared to tensioning NM group ( p < 0 . 05 ). In contrast, no significant changes were observed in the DSSEPs and skin sympathetic responses for participants in the sham treatment group ( p > 0 . 05 ).

Conclusions

A tensioning NM on the median nerve had a possible adverse effect on the neurophysiology variables of the nerves involved in the neural mobilization. Thus, tensioning NM with the current parameters that place increased stress and strain on the peripheral nervous system should be avoided.

Effectiveness of neural mobilization on pain intensity, disability, and physical performance in adults with musculoskeletal pain-A protocol for a systematic review of randomized and quasi-randomized controlled trials and planned meta-analysis

Recent studies show that musculoskeletal conditions contribute significantly to years lived with disability considering the entire global population. Pain and functional disability are the main problems that people with these conditions suffer. Neural mobilization has been shown to be an effective intervention in the treatment of musculoskeletal pain within individual trials, also contributing to improved functionality. Some systematic reviews have been carried out during the last years with the aim of synthesizing the scientific evidence on the use of neural mobilization techniques in the treatment of musculoskeletal disorders. However, they varied a lot in the methodological approaches and, consequently, in the findings and conclusions. Thus, this document is a planned protocol of a comprehensive systematic review with meta-analysis that we intend to carry out to review the scientific literature regarding up-to-date evidence on the use of neural mobilization in the management of people suffering from musculoskeletal pain disorders. The study designs that we will consider as inclusion criteria will be randomized and quasi-randomized clinical trials. The target population will be adults and older adults with musculoskeletal pain. Any controlled trial using any neural mobilization technique as an intervention in one of the trial groups will be included. The main outcomes of interest will be pain, functional status, and physical performance tests (muscle strength, flexibility, and balance). There will be no restrictions on follow-up time or type of setting. The risk of bias of the included studies will be assessed by the RoB 2 tool and the certainty of the evidence will be evaluated using the comprehensive Assessment, Development and Assessment of Assessment Recommendation (GRADE) approach. We intend to present the findings through narrative descriptions and, if possible, through meta-analytic statistics. Trial registration: PROSPERO registration number. CRD42021288387.

Treatment options for entrapment neuropathy of infrapatellar branch of saphenous nerve post knee arthroplasty: a case report

Background

The infrapatellar branch of the saphenous nerve is highly prone to form a neuroma or undergo transaction after midline incision of knee arthroplasty. The presence of neuroma and entrapment of these fibers can cause pain and numbness/tingling in the knee. The presence of these symptoms can significantly impact rehabilitation outcomes and long-term outcomes.

Case presentation

The patient is a 63-year-old Caucasian female reported to an outpatient orthopedic physical therapy clinic post left knee arthroplasty. The patient reported severe pain (VAS-9/10) with knee range of motion from 5 to 64° flexion. The lower extremity functional score was 42/80 with moderate deficits in function.

Conclusion

The anterior inferior knee pain with saphenous nerve entrapment can cause severe symptoms. Soft tissue mobilizations followed by neurodynamic techniques can improve neural mobility and functional outcomes (LEFS-52/80).

Update on Efficacy of Conservative Treatments for Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) is the most common upper extremity compression neuropathy. Non-operative interventions are usually the first-line treatments, and surgery is reserved for those that do not achieve a satisfactory symptom state by non-operative means. This narrative review summarizes the current evidence regarding the efficacy of orthoses, corticosteroid injections, platelet-rich plasma injections, Kinesio taping, neurodynamic techniques, gabapentin, therapeutic ultrasound, and extracorporeal shockwave therapy in people with CTS. While many trials suggest small short-term benefits, rigorous evidence of long-term patient-important benefits is limited. To improve the utility of healthcare resources, research in this area should focus on establishing efficacy of each treatment instead of comparing various treatments with uncertain benefits.

Short-term effects of dry needling of thenar muscles in manual laborers with carpal tunnel syndrome: a pilot, randomized controlled study

STUDY DESIGN

Pilot, randomized, single-blinded controlled clinical trial.

BACKGROUND AND OBJECTIVE

Trigger point (s) (TrPs) in thenar muscles could be a cause of narrowing of carpal tunnel in manual laborers with carpal tunnel syndrome (CTS). Effects of dry needling (DN) on the treatment of muscle tension have been reported, but no research has been done on the effect of DN on thenar tight muscles on reducing CTS symptoms. The aim of this study was to assess the effect of DN of thenar muscles TrPs in the treatment of mild-to-moderate carpal tunnel syndrome.

METHODS

Thirty manual laborers with mild-to-moderate CTS and the presence of TrP(s) in thenar muscles were randomized to DN group (n = 15) and control group (waiting list) (n = 15). The DN group received 2 sessions of DN of thenar muscles TrP(s), with a 48-h interval. The control group received no treatment. Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were the primary outcome, while secondary outcomes included electrophysiological domains, pinch and grip strength. Outcome measures were obtained at baseline, 48 hours, and 2 weeks after treatment (follow-up). Two-way analysis of variance (2 groups × 3 times) was used to compare within- and between-group differences. Bonferroni post hoc test was used to find any significant differences in the main effect for group, time, or interaction (group time).

RESULTS

A baseline assessment revealed no intergroup differences in all evaluated parameters (P > .05). Compared to the control group, the DN group had a statistically significant improvement in pinch and grip strength, median SDL, and BCTQ score after 2 weeks (P < .05). There were no between-group differences in the assessment of motor electrophysiologic and SNCV findings (P > .05).

CONCLUSION

Dry needling of thenar TrP(s) is effective in short-term improvement of function in manual laborers with mild-to-moderate CTS.

Effect of Neural Mobilization Exercises in Patients With Low Back-Related Leg Pain With Peripheral Nerve Sensitization: A Prospective, Controlled Trial

Objective

The aim of this study was to investigate the short-term effect of slider and tensioner exercises on pain and range of motion (ROM) of straight leg raise (SLR) and slump tests in patients with low back-related leg pain with peripheral nerve sensitization.

Methods

In this prospective, controlled trial, 51 patients with low back-related leg pain with peripheral nerve sensitization were divided into 3 treatment groups: slider (slider neural mobilization exercise + transcutaneous electric nerve stimulation [TENS]), tensioner (tensioner neural mobilization exercise + TENS), and control (only TENS). Each patient received 6 sessions over 2 weeks. The following outcomes were measured at baseline and after the first, third, and sixth sessions: visual analog scale (VAS) for pain and ROM of SLR and slump tests were performed for the symptomatic side.

Results

Compared with controls, patients receiving the slider and tensioner exercises showed a greater decrease in pain at the third and sixth sessions (mean difference: ≥1.54 cm; 95% CI, 0.1-3.9). There was a significant difference in the ROM of the SLR test between the slider and controls at only the sixth session (mean difference: 16.7°; 95% CI, -29.2 to -4.3). Patients in the slider and tensioner groups demonstrated greater improvements in the ROM of slump test at all sessions compared with controls (mean difference: ≥12.5°; 95% CI, -32.1 to -6.4). There were no significant differences between the slider and tensioner groups in any outcome at any session.

Conclusion

Patients in both slider and tensioner neural mobilization exercise groups demonstrated improvements in pain and ROM in patients with low back-related leg pain with peripheral nerve sensitization compared to those in the control group.

Manorah training alleviates median neural tension and improves physical fitness in sedentary young adults: A randomized control trial

INTRODUCTION

Most young adults do not achieve the recommended physical activity, and physical inactivity thus is a worldwide public health problem contributing to premature death. Although Thai dance has been reported to increase physical activity, a small number of studies have reported on the impact of Manorah. Herein Manorah is a signature traditional dramatic art of Southern Thailand. The present study aimed to reveal the effects of Manorah training on health-related variables.

METHODS

Thirty-four young females were divided into two groups, where one group underwent Manorah training and the other represented the control. Manorah training was performed for 45 min/day, 3 days/week for 4 weeks. Median neural tension, balance, flexibility, and muscle endurance were determined.

RESULTS

Manorah significantly decreased nerve tension (p < 0.001). Physical fitness was also markedly improved after the training.

CONCLUSIONS

This Manorah program may be recommended as an exercise and an intervention for symptoms related to positive tension.

Neurodynamics: is tension contentious?

Tensioning techniqueswere the first neurodynamic techniques used therapeutically in the management of people with neuropathies. This article aims to provide a balanced evidence-informed view on the effects of optimal tensile loading on peripheral nerves and the use of tensioning techniques. Whilst the early use of neurodynamics was centered within a mechanical paradigm, research into the working mechanisms of tensioning techniques revealed neuroimmune, neurophysiological, and neurochemical effects. In-vitro and ex-vivo research confirms that tensile loading is required for mechanical adaptation of healthy and healing neurons and nerves. Moreover, elimination of tensile load can have detrimental effects on the nervous system. Beneficial effects of tensile loading and tensioning techniques, contributing to restored homeostasis at the entrapment site, dorsal root ganglia and spinal cord, include neuronal cell differentiation, neurite outgrowth and orientation, increased endogenous opioid receptors, reduced fibrosis and intraneural scar formation, improved nerve regeneration and remyelination, increased muscle power and locomotion, less mechanical and thermal hyperalgesia and allodynia, and improved conditioned pain modulation. However, animal and cellular models also show that ‘excessive’ tensile forces have negative effects on the nervous system. Although robust and designed to withstand mechanical load, the nervous system is equally a delicate system. Mechanical loads that can be easily handled by a healthy nervous system, may be sufficient to aggravate clinical symptoms in patients. This paper aims to contribute to a more balanced view regarding the use of neurodynamics and more specifically tensioning techniques.

Effect of massage, passive neural mobilization and transcutaneous electrical nerve stimulation on magnetic resonance diffusion tensor imaging (MR-DTI) of the tibial nerve in a patient with type 2 diabetes mellitus induced neuropathy: a case report

BACKGROUND

MR-DTI parameters namely fractional anisotropy (FA) and apparent diffusion coefficient values (ADC) of diffusion imaging demonstrate the directional preference and speed of diffusion of water molecules. The purpose of this case report is to explore the effect of massage, passive neural mobilization and transcutaneous electrical nerve stimulation on MR-DTI of the tibial nerve in a patient with type 2 diabetes mellitus having chronic distal symmetrical sensorimotor neuropathy.

CASE DESCRIPTION

A 63-year-old male with type 2 diabetes mellitus diagnosed with chronic symmetrical sensorimotor diabetic peripheral neuropathy on the basis of medical examination and electrophysiological testing. Altered mechanosensitivity of the tibial nerve was confirmed through neurodynamic testing. MR-DTI revealed severe damage of the tibial nerve as shown by chaotic diffusion of water molecules and damaged microstructural integrity.

INTERVENTION

A total six sessions over 3 weeks including nerve massage in a longitudinal and transverse direction; passive neural mobilization consisting of sliders and tensioners of the tibial nerve; and followed by 15 minutes of continuous transcutaneous electrical nerve stimulation directed along the nerve course.

OUTCOME

FA and ADC values, pain,neuropathy quality of life and range of motion data were collected pre and post intervention. Analysis revealed clinical improvement in all the outcome measures.

CONCLUSION

This case report identified improvement in radiological MR-DTI outcomes following rehabilitation in a patient with diabetic peripheral neuropathy.
