The objective of this research was to advance understanding of shoulder disability. First, the DASH and its shorter version the QuickDASH questionnaires were compared for validity and responsiveness. Then, the ROM required by healthy subjects to perform five functional tasks was determined using video analysis software. The QuickDASH had items with a mean difficulty dispersed throughout the spectrum of the DASH items. Correlation of the QuickDASH with DASH was excellent (r>0.90). The QuickDASH and DASH were similar in ability to discriminate patients who were able to perform routine work from those who were not; and in responsiveness (SRM=0.51-1.06). This suggests that the QuickDASH is valid for patients undergoing TSA or RCR. Good to excellent intra-rater and inter-rater reliability for movement analysis was found; motion required for selected ADL were: 118±16 for flexion, 112±14 for abduction and 67±9 for extension. Video analysis can provide reliable scores; indicate targets for functional ROM.
