Abstract: Objective:The objective of this study was to examine the correlation between the Physiotherapy Evidence Database (PEDro) and the Downs and Black (D&B) quality assessment scale and the PEDro and a modified D&B assessment scores in a research synthesis of the ABI literature. Methods and Main Outcomes:A systematic review of the literature from 1980–2007 was conducted looking at treatment interventions following an ABI published in peer-reviewed English language journals. Of the articles chosen for inclusion in the study, 165 were identified as randomised controlled trials (RCT). All RCTs were scored using two quality assessment tools: the PEDro and D&B quality assessment scales. Items from these two scales were compared to identify which questions addressed similar information. Results:The association between the overall PEDro and D&B scores was moderately high (r = 0.71, p < 0.01) indicating a significant relationship between these two quality assessment tools. When considering the modified D& B scores, which contained a subset of questions deemed most comparable to the PEDro scale, the correlation between the two was also moderately high (r = 0.68, p < 0.01). Conclusions:Further analysis is required to investigate the strength of the relationship between these two scales in the assessment of RCTs.
