The effects of upper body blood flow restriction training on muscles located proximal to the applied occlusive pressure: A systematic review with meta-analysis

Background Blood flow restriction combined with low load resistance training (LL-BFRT) is associated with increases in upper limb muscle strength and size. The effect of LL-BFRT on upper limb muscles located proximal to the BFR cuff application is unclear. Objective The aim of this systematic review was to evaluate the effect of LL-BFRT compared to low load, or high load resistance training (LL-RT, HL-RT) on musculature located proximal to cuff placement. Methods Six electronic databases were searched for randomized controlled trials (RCTs). Two reviewers independently evaluated the risk of bias using the PEDro scale. We performed a meta-analysis using a random effects model, or calculated mean differences (fixed-effect) where appropriate. We judged the certainty of evidence using the GRADE approach. Results The systematic literature searched yielded 346 articles, of which 9 studies were eligible. The evidence for all outcomes was of very low to low certainty. Across all comparisons, a significant increase in bench press and shoulder flexion strength was found in favor of LL-BFRT compared to LL-RT, and in shoulder lean mass and pectoralis major thickness in favor of the LL-BFRT compared to LL-RT and HL-RT, respectively. No significant differences were found between LL-BFRT and HL-RT in muscle strength. Conclusion With low certainty LL-BFRT appears to be equally effective to HL-RT for improving muscle strength in upper body muscles located proximal to the BFR stimulus in healthy adults. Furthermore, LL-BFRT may induce muscle size increase, but these adaptations are not superior to LL-RT or HL-RT

The effects of upper limb exercise training on upper limb muscle strength in people with chronic obstructive pulmonary disease: a systematic review and meta-analysis of randomized controlled trials

Background: Upper limb (UL) muscle dysfunction is a common extrapulmonary manifestation of chronic obstructive pulmonary disease (COPD). UL muscle dysfunction is associated with muscle weakness, dyspnea, and exercise intolerance. Although upper limb exercise training (ULET) is typically incorporated in pulmonary rehabilitation programs, its effects on UL muscle strength remains unclear. Objectives: The purpose of this systematic review was to investigate the effectiveness of ULET, in UL muscle strength of people with COPD. Design: This is systematic review and meta-analysis study. Data Sources and Methods: Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Protocols 2020 guidelines were used for this study. PubMed, Cochrane, CINAHL Plus and SPORTDiscus and clinicaltrials.gov registry were searched from inception to July 2022. Included studies were randomized controlled trials, assessing the effectiveness in muscle strength of ULET, compared with other types of upper or lower limb exercise or no exercise. The quality and risk of bias were assessed using the Physiotherapy Evidence Database (PEDro) scale and certainty of evidence with the Grading of Recommendations, Assessment, Development, and Evaluations approach. Treatment effects of ULET were calculated using standardized mean differences and 95% confidence intervals. Results: Twenty-four studies, with a total sample of 882 patients, were included. Most studies were of moderate quality and high risk of bias. Very low to low certainty evidence indicates a significant difference in UL muscle strength in favor of resistance ULET, compared with lower limb exercise alone or no exercise. No significant differences were found in different types of ULET comparisons. Conclusion: The results of this review showed that resistance ULET could improve UL muscle strength in people with COPD. Most studies, however, were of moderate quality and high risk of bias. Further studies with larger sample sizes, better methodological quality, and standardized training protocols are needed to confirm these findings

Abstracts of the 9th International Organisation of Physical Therapy in Mental Health Conference

This book contains the abstracts of the papers presented at the 9th International Organisation of Physical Therapy in Mental Health Conference, Organized by the International Organisation of Physical Therapy in Mental Health and Greek Scientific Section “Physiotherapy in Mental Health” of PanHellenic Physiotherapists’ Association, held on 4–6 May 2022. It is the biannual conference of the International Organization of Physical Therapy in Mental Health (IOPTMH), and we answered with success the question: Physiotherapy in mental health; what’s next? The highly qualified scientific program, the reputable presenters, and the venue altogether form a powerful motivation for both physiotherapists and other mental health professionals to attend this conference.
