Abstract
To date, reviews of rehabilitation efficacy after traumatic brain injury (TBI) have overlooked the impact on sense of self, focusing instead on functional impairment and psychological distress. The present review sought to address this gap by critically appraising the methodology and efficacy of intervention studies that assess changes in self-concept. A systematic search of PsycINFO, Medline, CINAHL and PubMed was conducted from inception to September 2013 to identify studies reporting pre- and post-intervention changes on validated measures of self-esteem or self-concept in adults with TBI. Methodological quality of randomised controlled trials (RCTs) was examined using the Physiotherapy Evidence Database (PEDro) scale. A total of 17 studies (10 RCTs, 4 non-RCT group studies, 3 case studies) was identified, which examined the impact of psychotherapy, family-based support, cognitive rehabilitation or activity-based interventions on self-concept. The findings on the efficacy of these interventions were mixed, with only 10 studies showing some evidence of improvement in self-concept based on within-group or pre-post comparisons. Such findings highlight the need for greater focus on the impact of rehabilitation on self-understanding with improved assessment and intervention methodology. We draw upon theories of identity reconstruction and highlight implications for the design and evaluation of identity-oriented interventions that can supplement existing rehabilitation programmes for people with TBI.

Abstract
Evidence synthesized based on randomized controlled trials (RCT) results are recognized as the pinnacle of research excellence; however, the conduction of RCT in workplace environment is not always possible. This study comparatively reviewed evidence from RCT and non-RCT studies in which participants performed workplace exercise for musculoskeletal pain control. Up to February 2011, PubMed, MEDLINE, Embase, Cochrane, PEDro and Web of Science databases were searched. All trials that evaluated workplace exercise interventions for controlling musculoskeletal pain were included. The PEDro scale was used to rate the studies' quality, PRISMA and Cochrane recommendations were applied, and association between frequencies of effect size categories (small, moderate, large) from various outcomes by study type was tested (2x3 contingency table). The search yielded 10239 references in English, from which 21 RCT and 12 non-RCT were selected. Both groups of studies presented methodological flaws including descriptions of randomization, blinding of examiners and absence of intention-to-treat analysis for the RCT, and further absence of controls and blind assessor for the non-RCTs. RCTs had significantly more moderate and large effect size reported in their results compared to non-RCTs (p=0.04). Considering the difficulties in randomizing participants in occupational settings, all studies would benefit from better describing pertinent methodological information.
