Clinical effectiveness of non-surgical interventions for primary frozen shoulder: A systematic review.

Objective: To update an existing systematic review of randomized clinical trials evaluating the clinical effectiveness of non-surgical management interventions for people with primary frozen shoulder in terms of pain, movement, self-reported function and disability, quality of life, recovery time, return to work and recreation, and adverse events.

Data Sources: Cochrane CENTRAL, SCI and MEDLINE, CENTRAL between 1 January 2010 and June 2017, plus reference lists of included trials and trial registers. Abstracts were independently screened by 2 reviewers and discussed.

A prospective study exploring the construct and predictive validity of the COM-B model for physical activity.

This study examined the constructs of capability, opportunity and motivation from the COM-B model and their influence on moderate-to-vigorous physical activity. Using a prospective survey design, 186 healthy adults completed measures representing the theoretical domains framework mapped to the COM-B, and moderate-to-vigorous physical activity 1 week later. The main indicators for the COM constructs were 'habits' (Capability), 'subjective norms' (Opportunity) and 'exercise self-identity' (Motivation).

The Physiological Mechanisms of Effect of Vitamins and Amino Acids on Tendon and Muscle Healing: A Systematic Review.

Aims/objectives: To evaluate the current literature via systematic review to ascertain whether amino acids/vitamins provide any influence on musculotendinous healing and if so, by which physiological mechanisms.

Methods: EBSCO, PubMed, ScienceDirect, Embase Classic/Embase, and MEDLINE were searched using terms including "vitamins," "amino acids," "healing," "muscle," and "tendon." The primary search had 479 citations, of which 466 were excluded predominantly due to nonrandomized design.

Cross-national time trends in bullying victimization in 33 countries among children aged 11, 13 and 15 from 2002 to 2010.
