Study Design: A randomized controlled clinical trial. Objective: To investigate the effects of trigger point (TrP) manual therapy combined with a self-stretching program for the management of patients with plantar heel pain. Background: Previous studies have reported that stretching of the calf musculature and the plantar fascia are effective management strategies for plantar heel pain. However, it is not known if the inclusion of soft tissue therapy can further improve the outcomes in this population. Methods: Sixty patients, 15 men and 45 women (mean ± SD age, 44 ± 10 years) with a clinical diagnosis of plantar heel pain were randomly divided into 2 groups: a self-stretching (Str) group who received a stretching protocol, and a self-stretching and soft tissue TrP manual therapy (Str-ST) group who received TrP manual interventions (TrP pressure release and neuromuscular approach) in addition to the same self-stretching protocol. The primary outcomes were physical function and bodily pain domains of the quality of life SF-36 questionnaire. Additionally, pressure pain thresholds (PPT) were assessed over the affected gastrocnemii and soleus muscles, and over the calcaneus, by an assessor blinded to the treatment allocation. Outcomes of interest were captured at baseline and at a 1-month follow-up (end of treatment period). Mixed-model ANOVAs were used to examine the effects of the interventions on each outcome, with group as the between-subjects variable and time as the within-subjects variable. The primary analysis was the group-by-time interaction. Results: The 2 × 2 mixed-model analysis of variance (ANOVA) revealed a significant group-by-time interaction for the main outcomes of the study: physical function (P = .001) and bodily pain (P = .005); patients receiving a combination of self-stretching and TrP tissue intervention experienced a greater improvement in physical function and a greater reduction in pain, as compared to those receiving the self-stretching protocol. The mixed ANOVA also revealed significant group-by-time interactions for changes in PPT over the gastrocnemii and soleus muscles, and the calcaneus (all P<.001). Patients receiving a combination of self-stretching and TrP tissue intervention showed a greater improvement in PPT, as compared to those who received only the self-stretching protocol. Conclusions: This study provides evidence that the addition of TrP manual therapies to a self-stretching protocol resulted in superior short-term outcomes as compared to a self-stretching program alone in the treatment of patients with plantar heel pain.

Aim To summarise the current evidence regarding the effectiveness of physical therapy on pain, function and range of motion in individuals with subacromial pain syndrome (SAPS). Design Systematic review. Data sources PubMed, Web of Science, CINAHL, Cochrane, Embase, Lilacs, Ibecs and Scielo databases. Eligibility criteria for selecting studies Randomised controlled trials (RCTs) investigating physical therapy modalities for SAPS on pain, function/disability or range of motion were included. Results 64 high-quality RCTs were included. Exercise therapy provided high evidence of being as effective as surgery intervention and better than no treatment or placebo treatment to improve pain, function and range of motion in the short, mid and long terms. The combination of mobilisation and exercises provided high evidence to decrease pain and improve function in the short term. There is limited evidence for improvements on the outcomes with the isolated application of manual therapy. High level of evidence was synthesised regarding the lack of beneficial effects of physical resources such as low-level laser, ultrasound and pulsed electromagnetic field (PEMF) on pain, function or range of motion in the treatment of SAPS. There is limited evidence for microwave diathermy and transcutaneous electrical nerve stimulation. There is moderate evidence to no benefits with taping in the short term. Effects of diacutaneous fibrolysis and acupuncture are not well established yet. Conclusions Exercise therapy should be the first-line treatment to improve pain, function and range of motion. The addition of mobilisations to exercises may accelerate reduction of pain in the short term. Low-level laser therapy, PEMF and taping should not be recommended.

Study Design: Randomized controlled trial. Objective: To evaluate the effects of an exercise protocol, with and without manual therapy, on scapular kinematics, function, pain, and mechanical sensitivity in individuals with shoulder impingement syndrome. Background: Stretching and strengthening exercises have been shown to effectively decrease pain and disability in individuals with shoulder impingement syndrome. There is still conflicting evidence regarding the efficacy of adding manual therapy to an exercise therapy regimen. Methods: Forty-six patients were assigned to 1 of 2 groups, one of which received a 4-week intervention of stretching and strengthening exercises (exercise alone) and the other the same intervention, supplemented by manual therapy targeting the shoulder and cervical spine (exercise plus manual therapy). All outcomes were measured preintervention and postintervention at 4 weeks. Outcome measures were scapular kinematics in the scapular and sagittal planes during arm elevation, function as determined through the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, pain as assessed with a visual analog scale, and mechanical sensitivity as assessed with pressure pain threshold. Results: Independent of the intervention group, small, clinically irrelevant changes in scapular kinematics were observed postintervention. A significant group-by-time interaction effect (P = .001) was found for scapular anterior tilt during elevation in the sagittal plane, with a 3.0° increase (95% confidence interval [CI]: −1.5°, 7.5°) relative to baseline in the exercise-plus–manual therapy group compared to a decrease of 0.3° (95% CI: −4.2°, 4.8°) in the exercise-alone group. Pain, mechanical sensitivity, and the DASH score improved similarly for both groups by the end of the intervention period. Conclusion: Adding manual therapy to an exercise protocol did not enhance improvements in scapular kinematics, function, and pain in individuals with shoulder impingement syndrome. The noted improvements in pain and function are not likely explained by changes in scapular kinematics. The study is registered at www.clinicaltrials.gov (NCT02035618).

Case-control study. To analyze the differences in muscle size and shape of cervical multifidus between patients with bilateral chronic neck pain and healthy subjects. Researchers have demonstrated atrophy of lumbar multifidus in patients presenting with low back pain; however, there are only few published reports on cervical multifidus muscle size in individuals with chronic neck pain. Bilateral ultrasound images of multifidus muscle from the third to sixth cervical vertebrae (C3 to C6) were taken in 20 women with bilateral chronic neck pain and 20 healthy women. Cross-sectional area (CSA [cm2]) and muscle shape ratio (ratio between lateral [Lat] and anterior-posterior [AP] dimensions, [Lat/AP]) were measured without knowledge of group assignment. Two separate 3-way (4 x 2 x 2) mixed-model analyses of variance (ANOVAs) with cervical level (C3 to C6) and side (right, left) as within-subject factors and group (patient, control) as the between-subject factor, were used to evaluate differences in CSA and muscle shape ratio between groups, sides, and cervical levels. The ANOVA for CSA indicated a significant effect for cervical level (F = 6.81, P<.001) and group (F = 20.27, P<.001), but not for side (F = 1.26, P = .36). There were no significant interactions among the variables (P>.5). Post hoc analysis showed that the CSA of the C3 multifidus was smaller than the CSA of the C4 (P = .025), C5 (P<.001) or C6 (P<.01) multifidus. There was no significant difference between C4, C5, and C6 multifidus CSA (P>.05). The patients with neck pain had a smaller CSA of the cervical multifidus at all levels compared to controls (P<.001). The ANOVA for muscle shape ratio indicated a significant effect for level (F = 7.84, P<.001) and group (F = 12.501, P<.001), but not for side (F = 0.654, P = .58). There was a significant interaction between level and group (F = 3.651, P = .01). Patients had a wider ovoid shape (greater values in muscle shape ratio) of the C3 (P<.001) and C6 (P<.01) cervical multifidus compared to controls. Further, the C4 multifidus had a smaller shape ratio compared to C6 (P<.001), but was not significantly different than the shape ratio of the C3 and C5 (P>.05) multifidus. Females with bilateral chronic neck pain had generalized smaller CSA of the cervical multifidus muscles compared to healthy females.
