Immediate clinical benefits of combining therapeutic exercise and interferential therapy in adults with chronic neck pain: a randomized controlled trial

Comparative effectiveness of six biophysical agents on neck pain rehabilitation: a systematic review and network meta-analysis

PURPOSE

This systematic review and network meta-analysis aims to investigate the comparative effectiveness of six biophysical agents, including Transcutaneous electrical nerve stimulation (TENS), interferential current (IFC), extracorporeal shockwave therapy (ESWT), therapeutic ultrasound, low-level laser therapy (LLLT), and high-intensity laser therapy (HILT) on neck pain rehabilitation.

METHODS

Three bibliographic databases, PubMed, Embase, and Scopus were searched from inception to July 30, 2024. Randomized controlled trials comparing a single biophysical agent with placebo control or another biophysical agent on neck pain intensity as an outcome were selected. Two independent reviewers independently conducted study selection, data extraction, and quality assessment. The methodological quality of included randomized controlled trials was assessed using the Physiotherapy Evidence Database scale.

RESULTS

A total of 34 randomized controlled trials with 2141 patients with neck pain were included, and all included studies had good or above quality. A random-effects frequentist network meta-analysis, assuming a common random-effects standard deviation for all comparisons in the network. Effects of biophysical agents on neck pain intensity were estimated as mean differences with 95% confidence intervals. League tables were created to display the relative degree of neck pain for all comparisons among the six biophysical agents.

CONCLUSION

This study suggests that rehabilitation of neck pain using biophysical agents should be prioritized in the following ranks: HILT, ESWT, IFC, TENS, LLLT, and therapeutic ultrasound. The results clarified how different biophysical agents may influence neck pain outcomes and provided proper evidence to inform clinicians to select biophysical agents prudently for neck pain management.

Effects of adding electro-massage to manual therapy for the treatment of individuals with myofascial temporomandibular pain: a randomized controlled trial

OBJECTIVE

To evaluate the effect of the addition of dynamic cervical electrical stimulation (electro-massage, ES) to manual therapy (MT), compared to MT by itself, in individuals with myofascial temporomandibular pain.

METHODOLOGY

A total of 46 participants with bilateral myofascial temporomandibular pain for at least three months were distributed into two groups. Group 1 (n=21) received local MT consisting of soft tissue mobilization and release techniques over the neck and temporomandibular regions. Group 2 (n=25) received an ES procedure in the cervical region combined with the same intervention as group 1. All participants underwent a 2-week protocol. The primary outcomes were pain intensity (Visual Analogue Scale), pressure pain threshold (PPT) at the masseter and upper trapezius muscles (algometer), and pain-free vertical mouth opening (manual gauge). The secondary outcome was active cervical range-of-movement. Measurements were taken at baseline, immediately after intervention, and at a 4-week follow-up.

RESULTS

The ANOVA revealed significant changes over group*time, with better results for group 2 (large effect sizes) regarding pain intensity (p< 0.001; η2>0.14), pressure pain sensitivity and mouth opening (p<0.001; η2>0.14). Similar findings were observed for active cervical range-of-movement in all directions (p<0.001; η2>0.14), except rotation (p≥0.05).

CONCLUSION

Electrical stimulation therapy over the cervical region combined with a MT protocol over the neck and temporomandibular joint shows better clinical benefits than MT by itself in subjects with myofascial temporomandibular pain. Registration code: NCT04098952.

Psychophysiological responses to a multimodal physiotherapy program in fighter pilots with flight-related neck pain: A pilot trial

BACKGROUND

The physical and cognitive demands of combat flying may influence the development and persistence of flight-related neck pain (FRNP). The aim of this pilot study was to analyse the effect of a multimodal physiotherapy program which combined supervised exercise with laser-guided feedback and interferential current therapy on psychophysiological variables in fighter pilots with FRNP.

METHODS

Thirty-one fighter pilots were randomly assigned to two groups (Intervention Group: n = 14; Control Group: n = 17). The intervention consisted of 8 treatment sessions (twice per week) delivered over 4 weeks. The following primary outcomes were assessed: perceived pain intensity (Numeric Pain Rating Scale-NPRS) and Heart Rate Variability (HRV; time-domain, frequency-domain and non-linear variables). A number of secondary outcomes were also assessed: myoelectric activity of the upper trapezius and sternocleidomastoid, pain catastrophizing (Pain Catastrophizing Scale-PCS) and kinesiophobia (TSK-11).

RESULTS

Statistically significant differences (p≤0.05) within and between groups were observed for all outcomes except for frequency domain and non-linear HRV variables. A significant time*group effect (one-way ANOVA) in favour of the intervention group was found for all variables (p<0.001). Effect sizes were large (d≥0.6).

CONCLUSIONS

The use of a multimodal physiotherapy program consisting of supervised exercise with laser-guided feedback and interferential current appears to show clinical benefit in fighter pilots with FRNP.

Resistance, Motor Control, and Mindfulness-Based Exercises Are Effective for Treating Chronic Nonspecific Neck Pain: A Systematic Review With Meta-Analysis and Dose-Response Meta-Regression

OBJECTIVE: We aimed to analyze the effects and dose-response relationship of the most effective exercises for improving pain and disability in people with chronic nonspecific neck pain. DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: We searched the PubMed, PEDro, and CENTRAL databases from their inception to September 30, 2022. STUDY SELECTION CRITERIA: We included randomized controlled trials that involved people with chronic neck pain adopting a longitudinal exercise intervention and assessed one pain and/or disability outcome. DATA SYNTHESIS: Restricted maximum-likelihood random-effects meta-analyses were modeled separately for resistance, mindfulness-based, and motor control exercises; standardized mean differences (Hedge's g, standardized mean difference [SMD]) were effect estimators. Meta-regressions (dependent variable: effect sizes of the interventions; independent variables: training dose and control group effects) were conducted to explore the dose-response relationship for therapy success of any exercise type. RESULTS: We included 68 trials. Compared to true control, effects on pain and disability were significantly larger for resistance exercise (pain: SMD, -1.27; 95% confidence interval [CI]: -2.26, -0.28; |2 = 96%; disability: SMD, -1.76; 95% CI: -3.16, -0.37; |2 = 98%), motor control exercise (pain: SMD, -2.29; 95% CI: -3.82, -0.75; |2 = 98%; disability: SMD, -2.42; 95% CI: -3.38, -1.47; |2 = 94%), and Yoga/Pilates/Tai Chi/Qui Gong exercise (pain: SMD, 1.91; 95% CI:-3.28, -0.55; |2 = 96%; disability: SMD, -0.62; 95% CI: -0.85, -0.38; |2 = 0%). Yoga/Pilates/Tai Chi/Qui Gong exercise was more effective than other exercises (SMD, -0.84; 95% CI: -1.553, -0.13; |2 = 86%) for reducing pain. For disability, motor control exercise was superior to other exercises (SMD, -0.70; 95% CI: -1.23, -0.17; |2 = 98%). There was no dose-response relationship for resistance exercise (R2 = 0.32). Higher frequencies (estimate = -0.10) and longer durations (estimate = -0.11) of motor control exercise had larger effects on pain (R2 = 0.72). Longer sessions (estimate = -0.13) of motor control exercise had larger effects on disability (R2 = 0.61). CONCLUSION: Resistance, mindfulness-based, and motor control exercises were effective for reducing neck pain (very low- to moderate-certainty evidence). Higher frequencies and longer duration of sessions had a significant effect on pain for motor control exercise. J Orthop Sports Phys Ther 2023;53(8):1-41.

A Novel Method for Muscle Elongation in Myalgia with Naqvi's-Dynamic Electrical Therapy Approach (DELTA)©: The First-Ever Case Report

Lifestyle-related neck and shoulder pain can be attributed to trapezius myalgia (TM) in a significant number of cases. Apart from pain, manifestations of TM include tightness of the trapezius muscle, especially in the upper fibres. Naqvi's-Dynamic Electrical Therapy Approach (Naqvi's-DELTA)© is a novel electrotherapeutic intervention based on the principle of myofibril elongation obtained by interference of poled vector current that is moved along the length of muscle fibres. A 22-year-old male approached the physiotherapy outpatient department (OPD) with the chief complaint of persistent neck pain and stiffness for three years that adversely affected his activities of daily living (ADLs). The pain was evaluated using a visual analog scale (VAS), restrictions in the range of motion (ROM) were determined by the cervical range of motion (CROM) device, and limitations in ADLs were assessed by neck disability index (NDI). Naqvi's-DELTA© was administered once a day for seven days, with each session lasting for 15 minutes. After the intervention, an evident beneficial effect was noted in all outcomes measures suggesting that this novel method was effective in decreasing pain, stiffness, and limitations in ADLs. Further investigation to explore this method for myalgia management is warranted.

[Physical therapy in the treatment of complex regional pain syndrome]

The treatment of patients with complex regional pain syndrome (CRPS) takes place in an interdisciplinary and multimodal setting. Physical therapies represent a major treatment focus along with physiotherapy, occupational therapy, and analgetic treatments. This review explains their importance in current clinical practice and gives an impression of the evidence on different treatments including electrotherapy, neuromodulating procedures, manual lymphatic drainage, CO₂ applications and paraffin wax baths. As far as ascertainable from clinical experience and the scientific literature, treatment recommendations are presented in accordance with current guidelines.
