Efficacy of Myofascial Release With Transcutaneous Electrical Nerve Stimulation Conductive Glove for Neck Myofascial Syndrome: A Randomized Clinical Trial Study. J Manipulative Physiol Ther 2024:S0161-4754(24)00008-3. [PMID: 39127951 DOI: 10.1016/j.jmpt.2024.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/26/2024] [Accepted: 02/27/2024] [Indexed: 08/12/2024]
Abstract
OBJECTIVE The purpose of this study was to assess the efficacy of a myofascial release (MR) protocol applied with a transcutaneous electrical nerve stimulation (TENS) conductive glove. METHODS Eighty individuals with neck myofascial syndrome were randomly divided into 4 groups: (1) MR protocol with a TENS conductive glove (MR+TENS), (2) MR protocol without TENS (MR), (3) conventional TENS protocol (TENS), and (4) placebo TENS (control). All participants attended 6 sessions over a period of 3 weeks. The following measures were evaluated at baseline, at the third week, and at the 1-month follow-up: Pain with the visual analog scale (VAS pain), upper trapezius pressure pain threshold (PPT) with pressure algometry, cervical range of motion (ROM) with goniometry, and disability with the neck disability index (NDI). A 2-way ANOVA with repeated measurements was applied. RESULTS Significant changes between the 3 intervention groups and the control group were noted in the VAS and the NDI scores (P < .05) with the MR+TENS group exhibiting the biggest difference. Additionally, MR significantly increased PPT compared to TENS, and even further when applied with the conductive glove (P < .05). Regarding lateral flexion ROM, MR was equally effective either alone or in combination with the glove compared to TENS (P < .05). In contrast, TENS did not appear to affect neck PPT and ROM (P > .05). Finally, no difference between the groups was detected in cervical rotation ROM (P > .05). CONCLUSION The MR protocol appears to be more effective in dealing with pain, disability, and lateral flexion ROM than conventional TENS. A TENS conductive glove significantly improves the effects of MR, possibly due to the combined mechanical and electrical stimulation of the muscle.

Song JS, Kataoka R, Yamada Y, Wong V, Spitz RW, Bell ZW, Loenneke JP. The Hypoalgesic Effect of Low-Load Exercise to Failure Is Not Augmented by Blood Flow Restriction. RESEARCH QUARTERLY FOR EXERCISE AND SPORT 2023; 94:1084-1093. [PMID: 36094881 DOI: 10.1080/02701367.2022.2115443] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 08/16/2022] [Indexed: 06/15/2023]
Abstract
Purpose: To 1) examine whether blood flow restriction would provide an additional exercise-induced hypoalgesic response at an upper and lower limb when it is incorporated with low-load resistance exercise until failure, and 2) examine if increases in blood pressure and discomfort, with blood flow restricted exercise, would mediate the exercise-induced hypoalgesia over exercise without blood flow restriction. Methods: Forty healthy young participants completed two trials: four sets of unilateral knee extension exercise to failure at 30% of one-repetition maximum, with and without blood flow restriction. Pressure pain thresholds were assessed before (twice) and 5-min post exercise at an upper and lower limb. Blood pressure and discomfort ratings were recorded to examine mediating effects on exercise-induced hypoalgesia with blood flow restricted exercise. Results: Pressure pain threshold increased following both exercise conditions compared to a control, without any differences between exercise conditions at the upper (exercise conditions vs. control: ~0.37 kg/cm2) and lower (exercise conditions vs. control: ~0.60 kg/cm2) limb. The total number of repetitions was lower for exercise with blood flow restriction compared to exercise alone [median difference (95% credible interval) of -27.0 (-29.8, -24.4) repetitions]. There were no mediating effects of changes in blood pressure, nor changes in discomfort, for the changes in pressure pain threshold at either the upper or lower limb. Conclusion: The addition of blood flow restriction to low-load exercise induces a similar hypoalgesic response to that of non-blood flow restricted exercise, with a fewer number of repetitions.

Abstract
Background Strength-based exercise is widely used to treat tension-type headache, but the evidence of its benefit is unclear. This study aims to analyze the efficacy of a strength-based exercise program in patients with chronic tension-type headaches. Methods A randomized controlled trial with a 12-week strength-based exercise program, with chronic tension-type headache. The headache characteristics (which were the primary outcomes: frequency, duration, and intensity), cervical muscle thickness at rest or contraction of multifidus and longus-colli muscle, cervical range of motion, pain pressure threshold of temporalis, upper trapezius, masseter, tibialis muscle and median nerve, and cervical craniocervical flexion test were assessed at baseline and 12-weeks of follow-up in the intervention group (n = 20) and the control group (n = 20) was performed on 40 patients (85% women, aged 37.0 ± 13.3 years). Results Between baseline and week-12 of follow-up the intervention group showed statistically significant differences compared to control group in the following primary outcomes: duration and intensity of headaches. In addition, the intervention group improved the thickness of deep cervical muscles, reduced the peripheral sensitization, and improved the strength of deep cervical flexors. Conclusion A 12-week strength training of neck and shoulder region induced changes in pain intensity and duration, and physical-related factors in patients with TTH. Future interventions are needed to investigate if normalization of pain characteristics and physical factors can lead to an increase of headache-related impact.

Abstract
BACKGROUND Both spinal manipulation (SM) and Integrated Neuromuscular Inhibition Technique (INIT) have a positive effect in individuals with chronic neck pain (CNP), especially when they are combined with therapeutic exercise (TE). However, it has not been determined which of the above combinations is more effective in patients with CNP. OBJECTIVE To compare the efficacy of two different manual techniques (SM and INIT), when combined with the same TE program in the management of CNP. METHODS Eighty women with CNP, allocated into four groups of 20 persons each. The first group followed a 10-week TE program, the second TE and INIT, the third TE and SM, and the fourth was the control group. The Visual Analogue Scale (VAS) for pain, Neck Disability Index (NDI), Pressure Pain Threshold (PPT) of the neck muscles, neck active Range of Motion (ROM), Maximum Isometric Strength (MIS) of the neck muscles, craniocervical flexion test (CCFT) and SF-36 questionnaire scores were evaluated before, during and after the treatment period, with a six-month follow-up. RESULTS There was between groups differences between the three intervention groups and the control group (p< 05), with the positive effects being maintained until the six-month follow-up. However, this improvement occurred earlier in the "TE + INIT" and "TE + SM" groups than in the "TE" group. Differences between the "TE + INIT" and the "TE + SM" groups were noticed only in the neck muscles PPT values, in which the "TE + INIT" group showed greater improvement. Furthermore, some non-statistically significant indications for further improvement of "TE + SM" were noted in the left lateral flexion ROM. CONCLUSION The addition of INIT as well as SM in the same TE program can further increase the beneficial effect of exercise in women with CNP. In most measurements both combinations seem to be equally effective. However, INIT improved more local muscle tenderness, whereas SM aided more in the neck lateral flexion ROM.

The association between forward head posture and masticatory muscle pressure pain thresholds in patients with temporomandibular joint dissorders: a cross-sectional observational study. Clin Oral Investig 2023; 27:353-360. [PMID: 36241923 DOI: 10.1007/s00784-022-04739-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 10/02/2022] [Indexed: 02/01/2023]
Abstract
OBJECTIVES Forward head posture (FHP) is common in patients with temporomandibular joint disorders (TMDs); however, whether it contributes to TMD symptoms remains unclear. The aim of this study was to investigate the association between (1) FHP and masticatory muscle pressure pain thresholds (PPTs) and (2) neck muscle and masticatory muscle PPTs. MATERIALS AND METHODS A total of 145 patients diagnosed with TMD were recruited between December 2020 and April 2021. Data regarding FHP and neck and masticatory muscle PPTs were collected. FHP was characterized by the craniocervical angle (CVA) measured between the horizontal line through C7 and the line between the tragus of the ear and C7. Patients were divided into either the FHP group (CVA ≤ 51°) or the non-FHP group. Differences in the masseter and temporalis muscle PPTs between the two groups were analyzed using the Mann-Whitney U test. The correlation between the CVA, neck, and masticatory muscle PPTs in all patients was determined by Spearman's correlation analysis. RESULTS There were 70 patients in the FHP group and 75 patients in the non-FHP group. No significant difference in masseter and temporalis muscle PPTs was found between the two groups (p > 0.05). No correlation was found between FHP and masticatory muscle PPTs (p > 0.05). A significant association was found between the neck muscle and masticatory muscle PPTs (p < 0.05). The C5-C6 pillar and masticatory PPTs were either moderately (r = 0.435, masseter muscle) or strongly (r = 0.608, temporalis muscle) correlated, while the correlation between the trapezius and masticatory muscles was moderate (r = 0.378, masseter muscle and r = 0.461, temporalis muscle). CONCLUSION FHP was not directly associated with masticatory muscle PPTs. Masticatory muscle PPTs were strongly or moderately associated with neck muscle PPTs. Therefore, the presence of neck pain, not the degree of FHP, in patients with TMD is of significance. CLINICAL RELEVANCE In TMD treatment, we should pay attention to and actively relieve neck pain.

Abstract
OBJECTIVE This study aimed to quantitatively confirm the effects of dental specialists' work and stretching on musculoskeletal pain. METHODS The pain pressure threshold was divided into five parts (neck, shoulder, trunk, lower back, and hand/arm) of the upper body and measured at 15 muscle trigger points. The pain pressure threshold before and after work was measured, and 30 min of stretching and rest were stipulated as an intervention. RESULTS The pain pressure thresholds reduced significantly in all muscles after work (P < .05). In the stretching group, the pain pressure thresholds increased significantly in all muscles (P < .05). In particular, the iliocostalis lumborum (lower back), rhomboid (trunk), transverse carpal ligament (hand/arm), levator scapulae-superior angle (neck), and upper trapezius (shoulder) muscles showed the greatest decrease in pain pressure threshold after work and the greatest increase after stretching. CONCLUSIONS Stretching helps immediately relieve musculoskeletal pain in dental professionals and can prevent and manage work-related musculoskeletal disorders.

Abstract
It is well-established that a single bout of exercise can reduce pain sensitivity (i.e., exercise-induced hypoalgesia) in healthy individuals. However, exercise-induced hypoalgesia is often impaired in individuals with chronic pain. This might suggest that repeated bouts of exercise (i.e., exercise training) are needed in order to induce a reduction in pain sensitivity (i.e., training-induced hypoalgesia) among individuals with chronic pain, given that a single bout of exercise seems to be insufficient to alter pain. However, the effect of repeated bouts of exercise on pain sensitivity and its underlying mechanisms remain poorly understood. Therefore, the purpose of this review was to provide an overview of the existing literature on training-induced hypoalgesia, as well as discuss potential mechanisms of training-induced hypoalgesia and offer considerations for future research. Existing literature suggests that training interventions may induce hypoalgesic adaptations potentially driven by central nervous system and immune system factors. However, the limited number of randomized controlled trials available, along with the lack of understanding of underlying mechanisms, provides a rationale for future research.

Current Concept of Quantitative Sensory Testing and Pressure Pain Threshold in Neck/Shoulder and Low Back Pain. Healthcare (Basel) 2022; 10:healthcare10081485.

Abstract
In recent years, several published articles have shown that quantitative sensory testing (QST) and pressure pain threshold (PPT) are useful in the analysis of neck/shoulder and low back pain. A valid reference for normal PPT values might be helpful for the clinical diagnosis of abnormal tenderness or muscle pain. However, there have been no reliable references for PPT values of neck/shoulder and back pain because the data vary depending on the devices used, the measurement units, and the area examined. In this article, we review previously published PPT articles on neck/shoulder and low back pain, discuss the measurement properties of PPT, and summarize the current data on PPT values in patients with chronic pain and healthy volunteers. We also reveal previous issues related to PPT evaluation and discuss the future of PPT assessment for widespread use in general clinics. We outline QST and PPT measurements and what kinds of perceptions can be quantified with the PPT. Ninety-seven articles were selected in the present review, in which we focused on the normative values and abnormal values in volunteers/patients with neck/shoulder and low back pain. We conducted our search of articles using PubMed and Medline, a medical database. We used a combination of “Pressure pain threshold” and “Neck shoulder pain” or “Back pain” as search terms and searched articles from 1 January 2000 to 1 June 2022. From the data extracted, we revealed the PPT values in healthy control subjects and patients with neck/shoulder and low back pain. This database could serve as a benchmark for future research with pressure algometers for the wide use of PPT assessment in clinics.

Specific versus non-specific exercises for the neck extensor muscles in women with chronic idiopathic neck pain: A randomized controlled trial. Musculoskelet Sci Pract 2022; 60:102561. [PMID: 35421696 DOI: 10.1016/j.msksp.2022.102561] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 01/19/2022] [Accepted: 03/28/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Structural and functional impairments of the cervical extensor muscles have been demonstrated in people with neck pain. A global exercise approach targeting all neck extensor muscles has shown positive effects in this population. However, to date, the efficacy of exercises specifically targeting the deep neck extensors has neither been tested nor compared to global exercises for the neck extensors. OBJECTIVES To compare the effects on pain and disability of a specific lower deep neck extensors (SLDNE) versus a general neck extensor (GNE) exercise program in women with chronic idiopathic neck pain. METHODS Fourty-three women with chronic idiopathic neck pain were randomly allocated to either a six-week SLDNE or a GNE exercise program. As primary outcome, neck disability was measured with the Neck Disability Index (NDI). Secondarily, pain intensity (VAS), cervical ROM, pressure pain thresholds (PPTs), cervical and thoracic posture and self-perceived benefit of treatment (GROC) were also measured. Every outcome was measured at baseline and immediately after treatment, except NDI, which was also measured at 6-months follow-up. The GROC was only assessed post-intervention. RESULTS Both exercise programs lead to reduced neck disability immediately post-intervention (within-group mean difference [MD] = -6.09; 95% Confidence Interval [CI]: 7.75, -4.42 and -4.73; 95%CI: 6.57, -2.91 respectively) and at the 6-months follow-up (-4.47; 95%CI: 6.41, -2.53 and -4.74; 95%CI: 6.50, -2.97), but with no between group differences. Similar results were found for pain intensity post-intervention, with no between group interaction (within-group MD = -20.87 mm; 95% CI: 28.55, -13.19 and -18.00 mm; 95%CI: (-26.24, -9.76) for SLDNE and GNE groups, respectively). GROC improved after both interventions without any between-group difference. CONCLUSIONS A six-week exercise program specifically targeting the lower deep neck extensors lead to comparable outcomes as a general neck extensor exercise program in women with chronic idiopathic neck pain.

Abstract
OBJECTIVE To assess the extent to which pain sensitivity is altered in women with obesity with frequent knee symptoms who walk with either a hybrid training system (HTS) that provides antagonist muscle electrical stimulation vs sensory transcutaneous electrical nerve stimulation (TENS). DESIGN Randomized, double-blinded, controlled trial. SETTING University-based fitness center. PARTICIPANTS Twenty-eight women (N=28) with obesity, aged 40-70 years, with daily knee symptoms. INTERVENTIONS Participants were randomized to 12 weeks of biweekly 30-minute walking exercise with either HTS (HTSW group) or sensory TENS (control group). MAIN OUTCOME MEASURES Pressure pain thresholds (PPTs) at the more symptomatic knee (local PPT) and PPT at the ipsilateral pain-free wrist (remote PPT). RESULTS After adjustment for preintervention values and body mass index (BMI), there was a statistically significant improvement in local PPT in the HTSW group compared with the control group (P=.039). After adjustment for pretraining value, age, and BMI, changes in remote PPT when comparing groups did not reach statistical significance, although the HTS group tended to demonstrate increased remote PPT (P=.052) compared with the control group. Moreover, after adjustment for pretraining value, knee pain, and quality of life, comparing groups did not reach statistical significance, although the HTS group tended to demonstrate decreased knee pain (P=.069) compared with the control group. CONCLUSIONS Augmentation of walking exercise with HTS was more effective than application of sensory TENS in improving local pain sensitivity at the knee but not at the wrist in women with obesity with frequent knee symptoms.

Abstract
The purpose was to examine the effect of isometric handgrip exercise with and without blood flow restriction on exercise-induced hypoalgesia at a local and non-local site, and its underlying mechanisms. Sixty participants (21 males & 39 females, 18-35 years old) completed 3 trials: four sets of 2-minute isometric handgrip exercise at 30% of maximum handgrip strength; isometric handgrip exercise with blood flow restriction at 50% of arterial occlusion pressure; and a non-exercise time-matched control. Pain thresholds increased similarly in both exercise conditions at a local (exercise conditions: ~0.45 kg/cm2, control: ~-0.04 kg/cm2) and non-local site (exercise conditions: ~0.37 kg/cm2, control: ~-0.16 kg/cm2). Blood flow restriction induced greater feelings of discomfort compared to exercise alone [median difference (95% credible interval) of 4.5 (0.5, 8.6) arbitrary units]. Blood pressure increased immediately after exercise (systolic: 10.3 mmHg, diastolic: 7.7 mmHg) and decreased in recovery. There was no within participant correlation between changes in discomfort and pressure pain threshold. A bout of isometric handgrip exercise with or without blood flow restriction can provide exercise-induced hypoalgesia at a local and non-local site. However, discomfort and changes in systolic blood pressure do not explain this response.

Abstract
Aim: To compare effects of clinical Pilates and home exercises on postural disorders, strength and endurance of deep cervical flexors (DCF), cervical range of motion (CROM), pain intensity and functional disability in sagittal cervical disorientation. Patients & methods: Fourty six patients were included and divided into two groups. Clinical Pilates group performed stabilization based exercise and home exercise group performed conventional exercises. Results: Craniovertebral, head tilt, cervicothoracic angles and strength and endurance of DCF muscles had improvement in favor of clinical Pilates group (p < 0.05). There was no difference between groups in terms of right-left acromial distance, pain intensity, functional disability and CROM parameters (p > 0.05). Conclusion: Clinical Pilates exercises have been found to provide clinically significant improvements in craniovertebral, head tilt, cervicothoracic angles and strength and endurance of DCF muscles. However, in the increase of CROM, decreasing pain severity and functional impairment parameters there was no superiority of both exercise training. Clinical trial registration number: NCT03352921 (Clinicaltrials.gov).

Abstract
PURPOSE The present study aimed to investigate the relationship between the ultrasonography parameters of transversus abdominis and neck pain manifestations in women with chronic neck pain. MATERIALS AND METHODS Thirty women (mean age: 38.44 ± 9.56 years, BMI: 25.57 ± 3.32 kg/m2) with chronic neck pain were included in the study. The pain severity, disability scores, and bilateral pain pressure threshold of upper trapezius were assessed. The thickness of transversus abdominis in-rest and abdominal draw-in conditions were evaluated by two-dimensional ultrasonography. Pearson's correlation coefficients and linear regression statistics were determined. RESULTS We found a moderate correlation between the thickness of transversus abdominis in abdominal draw-in and the pain pressure threshold of right (r = 0.636, p < 0.001), and left upper trapezius (r = 0.403, p = 0.03). Moreover, there was a moderate correlation between the pain pressure threshold of the right upper trapezius and the thickness of transversus abdominis in-rest (r = 0.498, p = 0.006). No significant correlation was found between pain intensity, disability scores, and ultrasonography parameters of transversus abdominis. There was also a significant total effect of transversus abdominis' thickness on abdominal draw-in manoeuvre on predicting pain pressure threshold of right upper trapezius (B = 0.636, SE = 0.765, p < 0.001) and pain pressure threshold of left upper trapezius (B = 0.403, SE = 0.840, p = 0.03). CONCLUSIONS Our results revealed that upper trapezius muscle tenderness may associated with decreased muscle thickness of transversus abdominis. Addressing new exercise methodologies including transversus abdominis training in the management of chronic neck pain may be helpful to improve neck pain symptoms.

Abstract
OBJECTIVE To compare the effectiveness of different physical exercise interventions for chronic non-specific neck pain. DESIGN Systematic review and network meta-analysis. DATA SOURCES Electronic databases: AMED, CINAHL, Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Physiotherapy Evidence Database, PsycINFO, Scopus and SPORTDiscus. ELIGIBILITY CRITERIA Randomised controlled trials (RCTs) describing the effects of any physical exercise intervention in adults with chronic non-specific neck pain. RESULTS The search returned 6549 records, 40 studies were included. Two networks of pairwise comparisons were constructed, one for pain intensity (n=38 RCTs, n=3151 participants) and one for disability (n=29 RCTs, n=2336 participants), and direct and indirect evidence was obtained. Compared with no treatment, three exercise interventions were found to be effective for pain and disability: motor control (Hedges' g, pain -1.32, 95% CI: -1.99 to -0.65; disability -0.87, 95% CI: -1.45 o -0.29), yoga/Pilates/Tai Chi/Qigong (pain -1.25, 95% CI: -1.85 to -0.65; disability -1.16, 95% CI: -1.75 to -0.57) and strengthening (pain -1.21, 95% CI: -1.63 to -0.78; disability -0.75, 95% CI: -1.28 to -0.22). Other interventions, including range of motion (pain -0.98 CI: -2.51 to 0.56), balance (pain -0.38, 95% CI: -2.10 to 1.33) and multimodal (three or more exercises types combined) (pain -0.08, 95% CI: -1.70 to 1.53) exercises showed uncertain or negligible effects. The quality of evidence was very low according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. CONCLUSION There is not one superior type of physical exercise for people with chronic non-specific neck pain. Rather, there is very low quality evidence that motor control, yoga/Pilates/Tai Chi/Qigong and strengthening exercises are equally effective. These findings may assist clinicians to select exercises for people with chronic non-specific neck pain. PROSPERO REGISTRATION NUMBER CRD42019126523.

Abstract
OBJECTIVE to investigate the benefit of adding stretching exercises to cervical joint mobilization and active rotation exercises for patients with non-specific mechanical neck pain. METHODS Thirty-eight subjects with non-specific mechanical neck pain were randomly assigned to a standard procedure group (passive cervical mobilization and active cervical rotation range of motion exercise) or a combined procedure (passive cervical mobilization, active cervical rotation range of motion exercises, and stretching procedures). Mixed factorial analysis of variance was used to compare changes between groups over time in active cervical range of motion, Numeric Pain Rating Scale, Neck Disability Index, Global Rating of Change, and Pressure Pain Threshold. RESULTS There was a significant change in mean active range of motion in all directions, Pressure Pain Threshold, perceived pain, disability levels, and global rating of change over time (p < 0.001). There was a significant group by time interaction in mean active range of motion during extension (p = 0.01), right rotation (p = 0.004), right and left lateral flexion (p = 0.05, and p = 0.02 respectively). However, there was no significant group by time interaction in mean active range of motion during flexion, left rotation, pain intensity (p = 0.09), right and left pressure pain threshold (p = 0.30, 0.47, respectively), and disability (p = 0.07). CONCLUSIONS Both study groups improved significantly in all subjective and objective outcome measures. However, data from this study suggest that adding stretching to the standard procedures may be more effective than the standard procedure alone at improving cervical extension, right rotation, and lateral flexion active range of motion, but not pain and disability.

Abstract
BACKGROUND Algometry, as a highly sensitive method, provides an objective insight into the degree of pain, while the use of questionnaires can estimate the patient's psychological status in a simple way. OBJECTIVE This study was conducted in order to measure the pressure pain threshold in patients with cervical and lumbar radiculopathy and to find a possible association of pain with the anxiety and depression. METHODS The study examined 60 hospitalized patients with cervical radiculopathy and 60 patients with lumbar radiculopathy before starting and after finishing kinesitherapy. The research was conducted using the digital algometry device and Hospital Anxiety and Depression Scale. RESULTS There was no statistically significant difference in algometric values between the patients with cervical radiculopathy and the patients with lumbar radiculopathy. The program of rehabilitation did not lead to significant improvement in the level of pain. Females have a lower pressure pain threshold than males. Psychological factors greatly affect the pain. CONCLUSIONS The applied methods will provide the implementation of appropriate therapy and would achieve better verification of the results in a rehabilitation program. Radiculopathy in conservative therapy should be treated in cervical-thoracic and lumbar region together. Rehabilitation period for patients with radiculopathy have to be longer.

Abstract
OBJECTIVE Primarily to evaluate the completeness of the description of the clinical reasoning process in RCTs with patients with non-specific neck pain with an argued or diagnosed cause i.e. an impairment or activity limitation. Secondly, to determine the association between the completeness of the clinical reasoning process and the degree of risk of bias. DATA SOURCES Pubmed, Cinahl and PEDro were systematically searched from inception to July 2016. STUDY SELECTION RCTs (n = 122) with patients with non-specific neck pain receiving physiotherapy treatment published in English were included. DATA EXTRACTION Data extraction included study characteristics and important features of the clinical reasoning process based on the Hypothesis-Oriented Algorithm for Clinicians II (HOAC II)]. DATA SYNTHESIS Thirty-seven studies (30%) had a complete clinical reasoning process of which 8 (6%) had a 'diagnosed cause' and 29 (24%) had an 'argued cause'. The Spearmans rho association between the extent of the clinical reasoning process and the risk of bias was -0.2. CONCLUSIONS In the majority of studies (70%) the described clinical reasoning process was incomplete. A very small proportion (6%) had a 'diagnosed cause'. Therefore, a better methodological quality does not necessarily imply a better described clinical reasoning process.

Abstract
BACKGROUND While physical exercise is beneficial for back and neck-shoulder pain, only few intervention studies have evaluated effects on pain in multiple body regions. Furthermore, direct measurement of pain threshold can provide additional information to self-reported pain intensity. OBJECTIVES To evaluate the effect of workplace versus home-based physical exercise on pressure pain threshold (PPT) and musculoskeletal pain intensity in multiple body regions. STUDY DESIGN Secondary analysis of an examiner-blinded, cluster randomized controlled trial with allocation concealment. METHOD Two-hundred female healthcare workers from 18 departments at three hospitals were cluster-randomized to 10 weeks of: 1) home-based physical exercise (HOME) performed alone during leisure time for 5 × 10 min per week or 2) workplace physical exercise (WORK) performed in groups during working hours for 5 × 10 min per week and up to 5 motivational coaching sessions. PPT (neck, lower back, lower leg) and perceived pain intensity in multiple body regions (feet, knee, hips, lower and upper back, elbow, hand, shoulder, neck, and head) were measured at baseline and 10-week follow-up. RESULTS In some of the body regions, PPT and pain intensity improved more following WORK than HOME. Between-group differences at follow-up (WORK vs. HOME) were 41 kPA [95% CI 13-70, effect size (ES): 0.22] for PPT in the lower back, and -0.7 [95% CI -1.0-0.3, ES: 0.26] and -0.6 points [95% CI -0.9--0.2, ES: 0.23] for pain intensity in the lower back and feet, respectively. HOME did not improve more than WORK for any of the measurements. CONCLUSION Physical exercise recommendations for healthcare workers should consider the setting, i.e. performing supervised group-based exercise at work and motivational coaching sessions is more effective than exercising alone at home.

Abstract
OBJECTIVE Bruxism is discussed as an etiological factor in the pathogenesis of orofacial and cervical pain. As the sternocleidomastoid muscle (SCM) is co-activated during clenching, our aim was to investigate, whether the muscle loading leads to peripheral or central sensitizations. DESIGN In twenty-one healthy female volunteers, somatosensory profiles of the SCM were recorded according to the test battery of the German Research Network on Neuropathic Pain (DFNS) prior to and after an isometric muscle exercise. QST comprised thermal and mechanical stimuli. A submaximal activation of the SCM (15% MVC) was kept for 10min in sitting position. In separate test sessions one month apart, one sham and one verum experiment were conducted in randomized order. During the muscle loading, the parameters cold detection threshold (CDT), mechanical pain sensitivity (MPS) and pressure pain treshold (PPT) were tested and experimental pain recorded by visual analogoue scales (VAS). All test sessions were performed during the follicular phase of the menstrual cycle (day 5), to avoid effects on pain perception. Data were analyzed with Repeated Measures ANOVA (SPSS 22.0) RESULTS: No significant changes were found during or after (sham) loading except for stimulus-response-function (SR, P=0.01) and PPT (P=0.02) in the sham test. No effect was observed in the verum experiment (P=0.12 up to 1.0). CONCLUSION Prolonged low level contraction of the SCM does not evoke painful sensitization. In contrast, submaximal muscle activation seems to have a protective effect corresponding to a training effect preventing sensitization.

Abstract
BACKGROUND Regular Nordic Walking training could improve fitness and reduce tenderness in selected muscle groups in office workers. OBJECTIVE An assessment of the effects of a 12-week Nordic Walking training program on the perceived pain threshold (PPT) and the flexibility of selected upper-body muscle groups in postmenopausal female office workers. METHODS 39 office workers were selected at random for the treatment group (NWg, n = 20) and the control group (Cg, n = 19). The persons from the NW group completed a 12-week Nordic Walking training program (3 times a week/1 hour). PPTs measurements in selected muscles and functional tests evaluating upper-body flexibility (Back Scratch - BS) were carried out twice in every participant of the study: before and after the training program. RESULTS A significant increase in PPT (kg/cm2) was observed in the following muscles in the NW group only: upper trapezius (from 1,32 kg/cm2 to 1,99 kg/cm2), mid trapezius (from 2,92 kg/cm2 to 3,30 kg/cm2), latissimus dorsi (from 1,66 kg/cm2 to 2,21 kg/cm2) and infraspinatus (from 1,63 kg/cm2 to 2,93 kg/cm2). Moreover, a significant improvement in the BS test was noted in the NW group compared with the control group (from -1,16±5,7 cm to 2,18±5,1 cm in the NW group vs from -2,52±6,1 to -2,92±6,2 in the control group). CONCLUSIONS A 12-week Nordic Walking training routine improves shoulder mobility and reduces tenderness in the following muscles: trapezius pars descendens and middle trapezius, infraspinatus and latissimus dorsi, in female office workers.

Abstract
OBJECTIVES In viticulture, the prevalence of low back pain is particularly high among vineyard workers exposed to sustained and awkward postures. One promising setting for low back pain prevention resides in the implementation of workplace physical activity. METHODS This nonrandomized pilot study aims at evaluating the effects of a worksite supervised adapted physical activity program among 17 vineyard workers volunteered to enter either an intervention group (n = 10) or a control group (n = 7).The intervention group followed a physical activity program for 8 weeks involving (1) 15 minutes of warm-up every working day and (2) two weekly 1-hour adapted physical activity sessions targeting trunk muscle endurance and flexibility. The control group was advised to continue normal physical activity. Evaluations were carried out at weeks 0, 4, 8, and 12. Physical capacity was assessed using flexibility tests for the trunk, along with trunk muscle flexor and extensor endurance tests. Finally, pain sensitivity was evaluated by assessing pressure pain thresholds over 14 anatomical locations in the low back region. RESULTS For the intervention group, the endurance of the trunk extensor and flexor significantly increased from baseline to week 8 as well as the pressure pain thresholds. No change was observed for the control group over the same period. CONCLUSIONS These encouraging results in combination with the high adherence rate set interesting foundations for the promotion of worksite supervised adapted physical activity and, most likely, offer a new promising approach to prevent low back pain among vineyard workers.

Abstract
Background Manual pressure palpation is an examination technique used in the classification of myofascial pain syndrome (MPS) and fibromyalgia (FM). Currently, there are no validated systems for classifying results. A valid and reliable pressure pain threshold scale (PPTS) may provide a means for clinicians to grade, document, and report findings. The purpose of this investigation was to validate a PPTS in individuals diagnosed with MPS and FM. Intra-rater reliability, concurrent validity, minimum cut-off value, and patient responses were evaluated. Methods Eighty-four participants who met the inclusion criteria were placed into three groups of 28 (N = 84): MPS, FM, and asymptomatic controls. All participants underwent a two-part testing session using the American College of Rheumatology criteria for classifying FM. Part-1 consisted of manual palpation with a digital pressure sensor for pressure consistency and part 2 consisted of algometry. For each tender point (18 total), participants graded tenderness using the visual analog scale (VAS) while the examiner concurrently graded response using a five-point PPTS. Results The PPTS had good intra-rater reliability (ICC ≥ .88). A moderate to excellent relationship was found between the PPTS and VAS for all groups with the digital pressure sensor and algometer (ρ ≥ .61). A minimum cut-off value of 2 on the PPTS differentiated participants with MPS and FM from asymptomatic controls. Discussion The results provide preliminary evidence validating the PPTS for individuals with MPS and FM. Future research should further study the clinimetric properties of the PPTS with other chronic pain and orthopedic conditions. Levels of Evidence 2c.

Abstract
Background Neck pain is frequent among military helicopter pilots and crew-members, and pain may influence individual health and work performance. The aim of this study was to examine if an exercise intervention could reduce neck pain among helicopter pilots and crew-members. Methods Thirty-one pilots and thirty-eight crew-members were randomized to either an exercise-training-group (n = 35) or a reference-group (n = 34). The exercise-training-group received 20-weeks of specific neck/shoulder training. The reference-group received no training. Primary outcome: Intensity of neck pain previous 3-months (scale 0-10). Secondary outcomes: additional neck/shoulder pain intensity variables and pressure-pain-threshold in the trapezius muscle (TRA) and upper-neck-extensor muscles (UNE). Regular training adherence was defined as ≥1 training session a week. Statistical analyses performed were intention-to-treat and per-protocol. Students t-test was performed (p < 0.05). Results Intensity of neck pain previous 3-months at baseline was: 2.2 ± 1.8 and previous 7-days: 1.0 ± 1.5, and pressure-pain-threshold in TRA and UNE (right/left) was in kPa: 424 ± 187 / 434 ± 188 and 345 ± 157 / 371 ± 170 in the exercise-training-group, and 416 ± 177 / 405 ± 163 and 334 ± 147 / 335 ± 163 in the reference-group, with no differences between groups. Intention-to-treat-analysis revealed no significant between-group-differences in neck pain intensity and pressure-pain-threshold. Between-group-differences, including participants who trained regularly (n = 10) were also non-significant. Within-group-changes were significant among participants with regular training adherence in the exercise-training-group regarding intensity of neck pain previous 3-months (from 2.2 ± 0.6 to 1.3 ± 1.3, p = 0.019). Likewise, within the whole exercise-training-group, neck pain previous 7-days decreased (from 1.0 ± 1.4 to 0.6 ± 1.1, p = 0.024). Additional within-group-changes regarding pressure-pain-threshold in kPa were for the reference-group a reduction in TRA and UNE (right/left) to: 342 ± 143 / 332 ± 154 and 295 ± 116 / 292 ± 121 implying increased pain sensitivity, while for the exercise-training-group only a reduction in left TRA was seen: 311 ± 113. Conclusions The exercise intervention did not reduce neck pain among helicopter pilots and crew-members as no significant between-group-differences were found. However, some trends were demonstrated as some neck pain intensity and sensitivity improved more within the exercise-training-group but not within the reference-group. The lack of effect may be due to low adherence since only ~ 1/3 of subjects in the exercise-training-group engaged in regular training which may be due to the self-administration of the training.

Is exercise effective for the management of neck pain and associated disorders or whiplash-associated disorders? A systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration. Spine J 2016; 16:1503-1523.

Abstract
BACKGROUND CONTEXT In 2008, the Neck Pain Task Force (NPTF) recommended exercise for the management of neck pain and whiplash-associated disorders (WAD). However, no evidence was available on the effectiveness of exercise for Grade III neck pain or WAD. Moreover, limited evidence was available to contrast the effectiveness of various types of exercises. PURPOSE To update the findings of the NPTF on the effectiveness of exercise for the management of neck pain and WAD grades I to III. STUDY DESIGN/SETTING Systematic review and best evidence synthesis. SAMPLE Studies comparing the effectiveness of exercise to other conservative interventions or no intervention. OUTCOME MEASURES Outcomes of interest included self-rated recovery, functional recovery, pain intensity, health-related quality of life, psychological outcomes, and/or adverse events. METHODS We searched eight electronic databases from 2000 to 2013. Eligible studies were critically appraised using the Scottish Intercollegiate Guidelines Network criteria. The results of scientifically admissible studies were synthesized following best-evidence synthesis principles. RESULTS We retrieved 4,761 articles, and 21 randomized controlled trials (RCTs) were critically appraised. Ten RCTs were scientifically admissible: nine investigated neck pain and one addressed WAD. For the management of recent neck pain Grade I/II, unsupervised range-of-motion exercises, nonsteroidal anti-inflammatory drugs and acetaminophen, or manual therapy lead to similar outcomes. For recent neck pain Grade III, supervised graded strengthening is more effective than advice but leads to similar short-term outcomes as a cervical collar. For persistent neck pain and WAD Grade I/II, supervised qigong and combined strengthening, range-of-motion, and flexibility exercises are more effective than wait list. Additionally, supervised Iyengar yoga is more effective than home exercise. Finally, supervised high-dose strengthening is not superior to home exercises or advice. CONCLUSIONS We found evidence that supervised qigong, Iyengar yoga, and combined programs including strengthening, range of motion, and flexibility are effective for the management of persistent neck pain. We did not find evidence that one supervised exercise program is superior to another. Overall, most studies reported small effect sizes suggesting that a small clinical effect can be expected with the use of exercise alone.

Abstract
BACKGROUND Pressure pain thresholds (PPT) are commonly used to quantify mechanical pain sensitivity of deep structures. Excellent PPT reliability has been previously reported among the low back of healthy subjects. However, there is a lack of studies assessing PPT over the low back of workers exposed to biomechanical risk factors of low back pain. Thus, the purpose of this study was threefold: (1) to evaluate the intra-session absolute and relative reliability as well as minimal detectable change (MDC) values of PPT within 14 locations covering the low back region of vine-workers and (2) to determine the number of trial required to ensure reliable PPT assessments and (3) to assess the effect of modifier factors such as gender, age, body mass index (BMI) and pain intensity on PPT reliability. METHODS Twenty-nine vine-workers voluntarily participated in this study. Twenty-two reported low intensity of low-back pain while seven were pain-free. PPTs were assessed among 14 anatomical locations in the lower back region. Three trials were performed on each location with an interval time of at least one minute. Reliability was assessed computing intraclass correlation coefficients (ICC), standard error of measurement (SEM) for all possible combinations between trials. Bland-Altman plots were also generated to assess potential bias in the dataset. Finally, a repeated measure analysis of variance (RM-ANOVA) with the number of trials used as within subject factor was performed on (1) PPT, (2) ICC and (3) SEM values. RESULTS ICC ranged from 0.86 to 0.99 for all anatomical locations and for all possible combinations between trials. SEM for comparison between trial 1-2, 2-3, 1-3 and, 1-2-3 ranged from respectively, 36.7-77.5, 27.8-77.7, 50-95.2 and, 39.3-80.8 kPa. ICC and SEM remained similar to the ones obtained for the entire population when taking modifier factors in consideration. The visual analysis of Bland-Altman plots suggested small measurement errors for all anatomical locations and for all possible combinations between trials. CONCLUSIONS The assessment of PPTs of the lower back among vine-workers was found to have excellent relative and absolute reliability. Moreover, reliable measurements can be equally achieved when using the mean of three PPT measurement or with the first one.

Abstract
The assessment of pressure pain threshold (PPT) provides a quantitative value related to the mechanical sensitivity to pain of deep structures. Although excellent reliability of PPT has been reported in numerous anatomical locations, its absolute and relative reliability in the lower back region remains to be determined. Because of the high prevalence of low back pain in the general population and because low back pain is one of the leading causes of disability in industrialized countries, assessing pressure pain thresholds over the low back is particularly of interest. The purpose of this study study was (1) to evaluate the intra- and inter- absolute and relative reliability of PPT within 14 locations covering the low back region of asymptomatic individuals and (2) to determine the number of trial required to ensure reliable PPT measurements. Fifteen asymptomatic subjects were included in this study. PPTs were assessed among 14 anatomical locations in the low back region over two sessions separated by one hour interval. For the two sessions, three PPT assessments were performed on each location. Reliability was assessed computing intraclass correlation coefficients (ICC), standard error of measurement (SEM) and minimum detectable change (MDC) for all possible combinations between trials and sessions. Bland-Altman plots were also generated to assess potential bias in the dataset. Relative reliability for both intra- and inter- session was almost perfect with ICC ranged from 0.85 to 0.99. With respect to the intra-session, no statistical difference was reported for ICCs and SEM regardless of the conducted comparisons between trials. Conversely, for inter-session, ICCs and SEM values were significantly larger when two consecutive PPT measurements were used for data analysis. No significant difference was observed for the comparison between two consecutive measurements and three measurements. Excellent relative and absolute reliabilities were reported for both intra- and inter-session. Reliable measurements can be equally achieved when using the mean of two or three consecutive PPT measurements, as usually proposed in the literature, or with only the first one. Although reliability was almost perfect regardless of the conducted comparison between PPT assessments, our results suggest using two consecutive measurements to obtain higher short term absolute reliability.

Abstract
BACKGROUND Manual therapy (MT) and exercise have been extensively used to treat people with musculoskeletal conditions such as temporomandibular disorders (TMD). The evidence regarding their effectiveness provided by early systematic reviews is outdated. PURPOSE The aim of this study was to summarize evidence from and evaluate the methodological quality of randomized controlled trials that examined the effectiveness of MT and therapeutic exercise interventions compared with other active interventions or standard care for treatment of TMD. DATA SOURCES Electronic data searches of 6 databases were performed, in addition to a manual search. STUDY SELECTION Randomized controlled trials involving adults with TMD that compared any type of MT intervention (eg, mobilization, manipulation) or exercise therapy with a placebo intervention, controlled comparison intervention, or standard care were included. The main outcomes of this systematic review were pain, range of motion, and oral function. Forty-eight studies met the inclusion criteria and were analyzed. DATA EXTRACTION Data were extracted in duplicate on specific study characteristics. DATA SYNTHESIS The overall evidence for this systematic review was considered low. The trials included in this review had unclear or high risk of bias. Thus, the evidence was generally downgraded based on assessments of risk of bias. Most of the effect sizes were low to moderate, with no clear indication of superiority of exercises versus other conservative treatments for TMD. However, MT alone or in combination with exercises at the jaw or cervical level showed promising effects. LIMITATIONS Quality of the evidence and heterogeneity of the studies were limitations of the study. CONCLUSIONS No high-quality evidence was found, indicating that there is great uncertainty about the effectiveness of exercise and MT for treatment of TMD.

Fishbain DA, Gao J, Lewis JE, Zhang L. At Completion of a Multidisciplinary Treatment Program, Are Psychophysical Variables Associated with a VAS Improvement of 30% or More, a Minimal Clinically Important Difference, or an Absolute VAS Score Improvement of 1.5 cm or More? PAIN MEDICINE 2015; 17:781-9. [PMID: 26814242 DOI: 10.1093/pm/pnv006] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2015] [Accepted: 09/05/2015] [Indexed: 11/13/2022]
Abstract
OBJECTIVES Objectives were to determine at completion of a multidisciplinary pain program: 1) what percentage of chronic low back pain (CLBP) patients had improved at 30% or more (minimal clinically important difference [MCID]) and by 1.5 cm or more (minimal important change [MIC]) on the visual analog scale (VAS) and 2) whether that improvement is associated with pain matching (PM), pain threshold (PTRE), and pain tolerance (PTOL) improvements. METHODS One hundred and six CLBP patients had admission and discharge scores for VAS, PM, PTRE, and PTOL. Improvement was determined by absolute, MCID, and MIC VAS improvement. Logistic regression analysis controlling for age, gender, race, education, psychoactive substance dependence, and depression was utilized to develop models for the dependent variables of improvement of overall VAS; of MCID of 50% or more; and of MIC with PM, PTOL, and PTRE as independent variables. RESULTS Thirty-two percent and 35% of the CLBP patients were at MCID and MIC, respectively, at discharge (68% and 65% not at MCID and MIC, respectively), and 54.7% were improved overall. Of the improved patients, 59% were at MCID and 63.7% at MIC. PM was associated with overall VAS improvement, while PTRE and PM were associated with MCID improvement. MIC and 50% or above models could not be estimated. LIMITATIONS The VAS was treated as a ratio scale. CONCLUSIONS A significant percentage of CLBP patients were at MCID and at MIC at completion of multidisciplinary treatment. PM was associated with overall VAS improvement, while PTRE and PM were associated with MCID.

Abstract
Background and aims Investigation of the multidimensional correlates of pressure pain threshold (PPT) requires the study of large cohorts, and thus the use of multiple raters, for sufficient statistical power. Although PPT testing has previously been shown to be reliable, the reliability of multiple raters and investigation for systematic bias between raters has not been reported. The aim of this study was to evaluate the intrarater and interrater reliability of PPT measurement by handheld algometer at the wrist, leg, cervical spine and lumbar spine. Additionally the study aimed to calculate sample sizes required for parallel and cross-over studies for various effect sizes accounting for measurement error. Methods Five research assistants (RAs) each tested 20 pain free subjects at the wrist, leg, cervical and lumbar spine. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and systematic bias were calculated. Results Both intrarater reliability (ICC = 0.81-0.99) and interrater reliability (ICC = 0.92-0.95) were excellent and intrarater SEM ranged from 79 to 100 kPa. There was systematic bias detected at three sites with no single rater tending to consistently rate higher or lower than others across all sites. Conclusion The excellent ICCs observed in this study support the utility of using multiple RAs in large cohort studies using standardised protocols, with the caveat that an absence of any confounding of study estimates by rater is checked, due to systematic rater bias identified in this study. Implications Thorough training of raters using PPT results in excellent interrater reliability. Clinical trials using PPT as an outcome measure should utilise a priori sample size calculations.

Abstract
BACKGROUND Neck pain is common, disabling and costly. Exercise is one treatment approach. OBJECTIVES To assess the effectiveness of exercises to improve pain, disability, function, patient satisfaction, quality of life and global perceived effect in adults with neck pain. SEARCH METHODS We searched MEDLINE, MANTIS, ClinicalTrials.gov and three other computerized databases up to between January and May 2014 plus additional sources (reference checking, citation searching, contact with authors). SELECTION CRITERIA We included randomized controlled trials (RCTs) comparing single therapeutic exercise with a control for adults suffering from neck pain with or without cervicogenic headache or radiculopathy. DATA COLLECTION AND ANALYSIS Two review authors independently conducted trial selection, data extraction, 'Risk of bias' assessment and clinical relevance. The quality of the evidence was assessed using GRADE. Meta-analyses were performed for relative risk and standardized mean differences (SMD) with 95% confidence intervals (CIs) after judging clinical and statistical heterogeneity. MAIN RESULTS Twenty-seven trials (2485 analyzed /3005 randomized participants) met our inclusion criteria.For acute neck pain only, no evidence was found.For chronic neck pain, moderate quality evidence supports 1) cervico-scapulothoracic and upper extremity strength training to improve pain of a moderate to large amount immediately post treatment [pooled SMD (SMDp) -0.71 (95% CI: -1.33 to -0.10)] and at short-term follow-up; 2) scapulothoracic and upper extremity endurance training for slight beneficial effect on pain at immediate post treatment and short-term follow-up; 3) combined cervical, shoulder and scapulothoracic strengthening and stretching exercises varied from a small to large magnitude of beneficial effect on pain at immediate post treatment [SMDp -0.33 (95% CI: -0.55 to -0.10)] and up to long-term follow-up and a medium magnitude of effect improving function at both immediate post treatment and at short-term follow-up [SMDp -0.45 (95%CI: -0.72 to -0.18)]; 4) cervico-scapulothoracic strengthening/stabilization exercises to improve pain and function at intermediate term [SMDp -14.90 (95% CI:-22.40 to -7.39)]; 5) Mindfulness exercises (Qigong) minimally improved function but not global perceived effect at short term. Low evidence suggests 1) breathing exercises; 2) general fitness training; 3) stretching alone; and 4) feedback exercises combined with pattern synchronization may not change pain or function at immediate post treatment to short-term follow-up. Very low evidence suggests neuromuscular eye-neck co-ordination/proprioceptive exercises may improve pain and function at short-term follow-up.For chronic cervicogenic headache, moderate quality evidence supports static-dynamic cervico-scapulothoracic strengthening/endurance exercises including pressure biofeedback immediate post treatment and probably improves pain, function and global perceived effect at long-term follow-up. Low grade evidence supports sustained natural apophyseal glides (SNAG) exercises.For acute radiculopathy, low quality evidence suggests a small benefit for pain reduction at immediate post treatment with cervical stretch/strengthening/stabilization exercises. AUTHORS' CONCLUSIONS No high quality evidence was found, indicating that there is still uncertainty about the effectiveness of exercise for neck pain. Using specific strengthening exercises as a part of routine practice for chronic neck pain, cervicogenic headache and radiculopathy may be beneficial. Research showed the use of strengthening and endurance exercises for the cervico-scapulothoracic and shoulder may be beneficial in reducing pain and improving function. However, when only stretching exercises were used no beneficial effects may be expected. Future research should explore optimal dosage.

Open Orthop J 2014; 8:302-9. [PMID: 25320651 PMCID: PMC4195173 DOI: 10.2174/1874325001408010302] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2014] [Revised: 06/26/2014] [Accepted: 06/30/2014] [Indexed: 12/13/2022] Open
Abstract
The study was conducted to estimate the extent to which pressure pain sensitivity (PPS) and patient factors predict pain-related disability in patients with neck pain (NP), and to determine if PPS differs by gender. Forty-four participants with a moderate level of chronic NP were recruited for this cross sectional study. All participants were asked to complete self-reported assessments of pain, disability and comorbidity and then underwent PPS testing at 4-selected body locations. Pearson`s r w was computed to explore relationships between the PPS measures and the self-reported assessments. Regression models were built to identify predictors of pain and disability. An independent sample t-test was done to identify gender-related differences in PPS, pain-disability and comorbidity. In this study, greater PPS (threshold and tolerance) was significantly correlated to lower pain-disability (r = -.30 to -.53, p≤0.05). Age was not correlated with pain or disability but comorbidity was (r= 0.42-.43, p≤0.01). PPS at the 4-selected body locations was able to explain neck disability (R2=25-28%). Comorbidity was the strongest predictor of neck disability (R2 =30%) and pain (R2=25%). Significant mean differences for gender were found in PPS, disability and comorbidity, but not in pain intensity or rating. This study suggests that PPS may play a role in outcome measures of pain and disability but between-subject comparisons should consider gender and comorbidity issues.

Abstract
OBJECTIVE This analysis aimed to determine reliability, validity, and responsiveness of the pain on movement (POM) questionnaire, an instrument developed to determine pain intensity induced by head movement. DESIGN Data from nine randomized controlled trials for the treatment of chronic nonspecific neck pain were reanalyzed to determine reliability and validity of the POM questionnaire. METHODS POM was assessed as ratings of pain intensity induced by head movement in six different directions. The instrument's structure was assessed using a factor analysis. Reliability (internal consistency) was determined using Cronbach's alpha, and validity (convergent validity) was determined by correlating the POM with pain at rest on a visual analog scale (VAS), the neck disability index (NDI), quality of life (short-form 36 health survey questionnaire [SF-36]) and range of motion. Responsiveness was indicated by sensitivity to changes over time in a subsample of 49 patients. RESULTS Overall, 482 patients (mean age 50.3 ± 12.4 years, 72.3% female) were included in the analysis, and 458 of them provided complete data set for the POM. Average POM was 43.9 ± 20.8 mm on the VAS. The POM showed very good reliability as indicated by high internal consistency and moderate validity as indicated by significant correlations with the pain at rest, the NDI, and the SF-36. No correlations were found for POM with range of motion. The POM further proved to be responsive as it was sensitive to changes over time, and those changes were correlated to changes in pain intensity and NDI. CONCLUSIONS The POM seems to be a reliable and valid instrument to assess POM in patients with chronic nonspecific neck pain.

Abstract
[Purpose] Muscle co-contraction is important in stabilizing the spine. The aim of this
study was to compare cervical muscle co-contraction in adults with and without chronic
neck pain during voluntary movements. [Subjects and Methods] Surface electromyography of
three paired cervical muscles was measured in fifteen young healthy subjects and fifteen
patients with chronic neck pain. The subjects performed voluntary neck movements in the
sagittal and coronal plane at slow speed. The co-contraction ratio was defined as the
normalized integration of the antagonistic electromyography activities divided by that of
the total muscle activities. [Results] The results showed that the co-contraction ratio of
patients was greater during flexion movement, lesser during extension movement, slightly
greater during right lateral bending, and slightly lesser during left lateral bending
compared with in the controls. [Conclusion] The results suggested that neck pain patients
exhibit greater antagonistic muscle activity during flexion and dominate-side bending
movements to augment spinal stability, while neuromuscular control provides relatively
less protection in the opposite movements. This study helps to specify the changes of the
stiffness of the cervical spine in neck pain patients and provides a useful tool and
references for clinical assessment of neck disorders.

Abstract
BACKGROUND Physical therapy influences chronic pain by means of the specific ingredient of an intervention as well as contextual factors including the setting and therapeutic alliance (TA) between provider and patient. OBJECTIVE The purpose of this study was to compare the effect of enhanced versus limited TA on pain intensity and muscle pain sensitivity in patients with chronic low back pain (CLBP) receiving either active or sham interferential current therapy (IFC). DESIGN An experimental controlled study with repeated measures was conducted. Participants were randomly divided into 4 groups: (1) AL (n=30), which included the application of active IFC combined with a limited TA; (2) SL (n=29), which received sham IFC combined with a limited TA; (3) AE (n=29), which received active IFC combined with an enhanced TA; and (4) SE (n=29), which received sham IFC combined with an enhanced TA. METHODS One hundred seventeen individuals with CLBP received a single session of active or sham IFC. Measurements included pain intensity as assessed with a numerical rating scale (PI-NRS) and muscle pain sensitivity as assessed via pressure pain threshold (PPT). RESULTS Mean differences on the PI-NRS were 1.83 cm (95% CI=14.3-20.3), 1.03 cm (95% CI=6.6-12.7), 3.13 cm (95% CI=27.2-33.3), and 2.22 cm (95% CI=18.9-25.0) for the AL, SL, AE, and SE groups, respectively. Mean differences on PPTs were 1.2 kg (95% CI=0.7-1.6), 0.3 kg (95% CI=0.2-0.8), 2.0 kg (95% CI=1.6-2.5), and 1.7 kg (95% CI=1.3-2.1), for the AL, SL, AE, and SE groups, respectively. LIMITATIONS The study protocol aimed to test the immediate effect of the TA within a clinical laboratory setting. CONCLUSIONS The context in which physical therapy interventions are offered has the potential to dramatically improve therapeutic effects. Enhanced TA combined with active IFC appears to lead to clinically meaningful improvements in outcomes when treating patients with CLBP.

Abstract
OBJECTIVES Pain is a common symptom with high occurrence in somatoform syndromes and depressive disorders. Research in this area often focuses on experimental induction of pain and subsequent assessment of pain thresholds, ensuring repeatable stimuli of defined quality. Results on sensitivity to experimental pain in major depression are inconclusive, and data on pain thresholds in multiple somatoform symptoms are scarce. The goals of the present study were to differentiate between groups regarding the pressure pain thresholds, and to investigate the possible influence of physical activity on the pain thresholds in these groups. We postulate that physical fitness and physical activity influence pain thresholds in depression and persons with multiple somatoform symptoms. METHODS Thirty-eight persons with major depression, 26 persons with a minimum of 6 to 8 somatoform symptoms (somatoform symptom index 8, SSI-8), and 47 healthy participants participated in the study. Baseline values of pressure pain thresholds assessed at different sites of the body were compared with those after 1 week of increased and 1 week of reduced physical activity. RESULTS We used repeated measurement design (MANCOVA) and partial correlations for data analysis. Depressed participants reported lower pain thresholds compared with controls, and persons with SSI-8 showed intermediate thresholds. After 1 week of physical activity, participants reported higher pain thresholds. Men had higher pain thresholds following activity as compared with women. Participants who reported higher general fitness also showed higher pain thresholds. Sensitivity to pressure pain is associated with depression, but not with multiple somatoform symptoms. DISCUSSION Short low-graded exercise can have reducing effects on perception of pressure pain. Physical activity level is a relevant covariate when using pressure pain assessment. Reduced general fitness can partially account for lower pain thresholds in depression.

Abstract
BACKGROUND Neck disorders are common, disabling and costly. The effectiveness of exercise as a physiotherapy intervention remains unclear. OBJECTIVES To improve pain, disability, function, patient satisfaction, quality of life and global perceived effect in adults with neck pain. SEARCH METHODS Computerized searches were conducted up to February 2012. SELECTION CRITERIA We included single therapeutic exercise randomized controlled trials for adults with neck pain with or without cervicogenic headache or radiculopathy. DATA COLLECTION AND ANALYSIS Two review authors independently conducted selection, data extraction, 'Risk of bias' assessment, and clinical relevance. The quality of the body of evidence was assessed using GRADE. Relative risk and standardized mean differences (SMD) were calculated. After judging clinical and statistical heterogeneity, we performed meta-analyses. MAIN RESULTS Six of the 21 selected trials had low risk of bias. Moderate quality evidence shows that combined cervical, scapulothoracic stretching and strengthening are beneficial for pain relief post treatment (pooled SMD -0.35, 95% confidence interval (CI): -0.60, -0.10) and at intermediate follow-up (pooled SMD -0.31, 95% CI: -0.57, -0.06), and improved function short term and intermediate term (pooled SMD -0.45, 95% CI: -0.72, -0.18) for chronic neck pain. Moderate quality evidence demonstrates patients are very satisfied with their care when treated with therapeutic exercise. Low quality evidence shows exercise is of benefit for pain in the short term and for function up to long-term follow-up for chronic neck pain. Low to moderate quality evidence shows that chronic neck pain does not respond to upper extremity stretching and strengthening or a general exercise program.Low to moderate quality evidence supports self-mobilization, craniocervical endurance and low load cervical-scapular endurance exercises in reducing pain, improving function and global perceived effect in the long term for subacute/chronic cervicogenic headache. Low quality evidence supports neck strengthening exercise in acute cervical radiculopathy for pain relief in the short term. AUTHORS' CONCLUSIONS Low to moderate quality evidence supports the use of specific cervical and scapular stretching and strengthening exercise for chronic neck pain immediately post treatment and intermediate term, and cervicogenic headaches in the long term. Low to moderate evidence suggests no benefit for some upper extremity stretching and strengthening exercises or a general exercise program. Future trials should consider using an exercise classification system to establish similarity between protocols and adequate sample sizes. Factorial trials would help determine the active treatment agent within a treatment regimen where a standardized representation of dosage is essential. Standardized reporting of adverse events is needed for balancing the likelihood of treatment benefits over potential harms.

Abstract
A position of scapula depression will maintain the upper trapezius muscle region in a lengthened position, causing excessive strain. This strain could lead to peripheral nociceptive nerves sensitization in the affected area, changing the pressure pain threshold (PPT). Thus, people with a faulty alignment of scapular depression may have lower PPT levels in the upper trapezius region when compared to subjects with normal vertical scapular position. The purpose of this double-blind study was to assess the influence of scapular position on the PPT of the upper trapezius region in a young healthy population. Fifty two physical therapy students of the Catholic University of Minas Gerais-PUC-Minas, Brazil, with normal shoulder (NS group, n=26, 6 men and 20 women) or depressed shoulder (DS group, n=26, 6 men and 20 women) volunteered to participate in this study. An electronic pressure algometer was used to measure the PPT on the upper trapezius muscle region. The results showed a significant difference between groups, with the DS group (19.0+/-9.0 N/cm(2)) demonstrated lower mean PPT values when compared to NS group (26.1+/-9.6 N/cm(2)) (p<0.01). Our results showed that healthy young subjects with depressed scapula position had significant lower upper trapezius PPT values when compared to subjects with normal scapula position.
