Abstract BACKGROUND: Although achieving quality of movement after stroke is an important aim of physiotherapy it is rarely measured objectively or described explicitly. OBJECTIVE: To test whether physiotherapists agree on a composite measure of quality of movement. SETTING; A movement analysis laboratory SUBJECTS: Ten stroke patients and 10 healthy age-matched volunteers. DESIGN: Prospective correlational. PROCEDURE: All subjects were videofilmed performing three trials of six standardized functional tasks. Two videotapes were made, each with a different randomized order of appearance of the trials. Ten senior physiotherapists independently rated the videotapes twice using a 100-mm visual analogue scale. ANALYSIS: Analysis of variance models were fitted to transformed data. Estimates of components of variance were calculated and presented as a percentage of the total variance for differences, within subjects (intra-subject), between raters (inter-rater) and within raters (intra-rater). An acceptable percentage was set at less than 10\%. RESULTS: The percentage of intra-subject variance ranged from 1\% (pick up box and walking) to 9\% (step on block). The percentage of inter-rater variance ranged from 18\% (pick up pencil) to 38\% (sit to stand). The percentage of intra-rater variance was less than 1\% for all tasks. CONCLUSIONS: Although physiotherapists disagreed with each other on quality of movement they were more consistent in their own scoring.
