Is manual therapy of the diaphragm effective for people with obstructive lung diseases? A systematic review.

BACKGROUND: Diaphragm dysfunction is common among people with obstructive lung disease (OLD). The effectiveness of manual therapy (MT) techniques specifically targeting this region remains unclear. The scope of this systematic review is to investigate the effectiveness of MT on the zone of apposition (ΖΟΑ) of the diaphragm in lung function, diaphragm excursion (DE), chest expansion, exercise capacity (EC), maximal inspiratory pressure (PImax) and dyspnea in people suffering from OLD. METHODS: Key databases were systematically searched. Two independent reviewers screened the papers for inclusion. Methodological quality and the quality of evidence were assessed using the PEDro scale and the GRADE approach, respectively. RESULTS: Two studies were included. One showed that diaphragmatic stretching and the manual diaphragm release technique (MDRT) improved DE and CE (p<0.001, p<0.05, respectively). The other showed that MDRT improved DE and EC (p<0.05, p<0.05, respectively). CONCLUSION: This systematic review provides preliminary evidence on the effectiveness of MT on the ZOA of the diaphragm in people with COPD. Further research is needed in order for definitive conclusions to be drawn. REGISTRATION NUMBER IN PROSPERO: CRD42022308595.

Electromyographic Activity of Sternocleidomastoid Muscle in Individuals With Neck Pain and Healthy Volunteers: A Reliability and Between-Group Differences Examination.

OBJECTIVES: The purpose of this study was to evaluate the electromyographic activity of the sternocleidomastoid muscle during the performance of the craniocervical flexion test (CCFT) in individuals with neck pain and healthy volunteers, assess the reliability of this method, and examine possible between-population differences. METHODS: Electromyographic activity of the sternocleidomastoid muscles of 22 individuals with neck pain and 22 healthy participants was recorded during the 55 stages of the CCFT. Pain (visual analog scale) and disability (Neck Disability Index) levels and pain duration were recorded for the participants with neck pain. Reliability of electromyography was evaluated with the intraclass correlation coefficient, standard error of measurement, and minimum detectable change. RESULTS: Within-day reliability indices of electromyographic activity were very good to excellent (intraclass correlation coefficients, 0.86-0.98; standard error of measurement, 1.8%-7.6%; minimum detectable change, 5.0%-21.1%). For the head-lift normalization method, 2-way analysis of variance revealed significant between-group differences (P < .02); however, these were not clinically significant when reliability test-retest error was considered. Differences between contraction levels were significant (P < .001); however, the group by contraction level interaction factor was nonsignificant. Therefore, the between-groups electromyographic increases noted with increasing contraction levels were similar. No correlation was identified between participants' electromyography data and pain or disability. CONCLUSION: In participants with moderate pain, disability, and pain duration, no clear alterations in electromyographic activity of the sternocleidomastoid could be detected with the CCFT. Reliability of the test used was very good.

The immediate effect of IASTM vs. Vibration vs. Light Hand Massage on knee angle repositioning accuracy and hamstrings flexibility: A pilot study.

INTRODUCTION: The effectiveness of novel soft-tissue interventions relative to traditional ones requires further exploration. The purpose of this pilot study was to evaluate the immediate effect of Instrument Assisted Soft Tissue Mobilization (IASTM) compared to Vibration Massage or Light Hand Massage on hamstrings' flexibility and knee proprioception. METHODS: 16 healthy non-injured male participants (mean age 23.7 years, height 1.80 cms and body mass 77.7 kg) were randomly assigned to the following interventions: (a) 5min IASTM, (b) 5min Vibration Massage and (c) 8min Light Hand-Massage, sequentially delivered to all participants with an in-between 1-week time interval. A single application of each intervention was given over the hamstrings of their dominant leg (repeated measures under 3 different experimental conditions). An active knee angle reproduction proprioception test and the back-saver sit and reach flexibility test were performed before and immediately after each intervention. Reliability of outcomes was also assessed. RESULTS: Reliability for flexibility (ICC3,1 = 0.97-0.99/SEM = 0.83-1.52 cm) and proprioception (ICC3,1 = 0.83-0.88/SEM = 1.63-2.02°) was very good. For flexibility, statistically significant immediate improvement (p < 0.001) was noted in all 3 groups (1.61-3.23 cm), with no between-group differences. For proprioception, improvement in the IASTM (2.12°), Vibration Massage (0.32°) and Light Hand-Massage (1.17°) conditions was not statistically significant; no between-group differences were also evident. CONCLUSIONS: Our findings indicate that muscle flexibility was positively influenced immediately after a single intervention of IASTM, Vibration Massage or Light Hand Massage. Proprioception changes were not statistically significant either within or between groups. Further evaluation of those interventions in a larger population with hamstrings pathology is required.

Effectiveness of Mulligan's Mobilization With Movement Techniques on Range of Motion in Peripheral Joint Pathologies: A Systematic Review With Meta-analysis Between 2008 and 2018.

OBJECTIVES: The purpose of this study was to provide an updated systematic review and meta-analysis regarding the effectiveness of mobilization with movement (MWM) techniques on range of motion (ROM). METHODS: An electronic search strategy of the Physiotherapy Evidence Database, PubMed, Cochrane Library, Embase, Google Scholar, and CINAHL was performed between August 2008 and January 2018. Two independent reviewers selected the studies. Only randomized controlled trials were included. The methodology was independently assessed by 2 reviewers using the Physiotherapy Evidence Database scale. The Z indicator was considered for the assessment of statistical significance of ROM change, whereas for each meta-analysis referring to a specific joint pathology, the total mean difference (95% confidence interval) was compared against minimum detectable change values from relevant studies conducted in similar populations to assess clinical significance. RESULTS: Included were 18 studies with 753 participants in 10 separate meta-analyses for ROM. All studies were classified as high quality or medium quality. Peripheral joint MWM seems to produce better therapeutic results in comparison to sham, passive, other active, or no therapeutic approach, regarding improvement of joint ROM in specific peripheral joint pathologies, consistently in all movement directions for shoulder adhesive capsulitis (mean improvement 12.30o-26.09o, P < .02) and hip pain (mean improvement 4.50o-14.80o, P < .0001). CONCLUSION: Mobilization with movement produced a statistically and clinically significant ROM increase consistently in all movement directions for shoulder adhesive capsulitis and hip pain. However, for shoulder impingement, shoulder pain/dysfunction, hamstring tightness, knee osteoarthritis, and chronic ankle instability pathologies, a therapeutic benefit regarding ROM could not be clearly established. Owing to the small number of individual studies included within the separate groups of pathologies examined in our systematic review, methodologically rigorous studies with longer follow-up periods are warranted to better inform the evidence base on the effects of MWM on ROM.

Effectiveness of Mulligan's mobilization with movement techniques on pain and disability of peripheral joints: a systematic review with meta-analysis between 2008-2017.

BACKGROUND: The Mulligan method of manual therapy advocates the use of 'mobilization with movement (MWM)' techniques to effectively manage peripheral joint 'positional fault' dysfunctions. OBJECTIVES: To provide an updated evidence-based systematic review and meta-analysis regarding the effectiveness of MWM techniques. DATA SOURCES: PubMed, EBSCOhost, PEDro, Cochrane Library and Google Scholar between 1st August 2008-31st August 2017. STUDY SELECTION: Two reviewers applied the population intervention comparison outcome (PICO) question to screen the studies for this review. Only RCTs/CCTs were included. DATA EXTRACTION: Information on study design, subjects, intervention, outcome measures and efficacy results were extracted. Methodological quality was independently assessed by two reviewers using the PEDro Scale. DATA SYNTHESIS: Sixteen studies with 576 participants were included in four separate meta-analyses for pain and disability. The I2 index assessed the heterogeneity between studies. RESULTS: MWMs have demonstrated statistically significant improvements against sham treatment, passive and control intervention techniques for pain [mean difference (95%CI):-16.12 (-19.77, -12.48) & I=72%] and disability [mean difference (95%CI):-17.51 (-22.84, -12.19) 2 2 2 2 & I=88%] or against another manual therapy treatment [pain mean difference (95%CI): -10.43 (-11.38, -9.48) & I=0%], however not against another manual therapy treatment for disability. The clinical significance of the pooled differences was compared against Minimal Clinically Important Difference values. LIMITATIONS: No long-term effectiveness data were identified in any of the included studies. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: The overall post-intervention short-term statistical and clinical significance of MWM techniques has been verified, although the high heterogeneity identified may require further validation of those methods. Systematic review registration number: PROSPERO 2016:CRD42017071595.
