Intra- and inter-rater reliability of the Modified Frenchay Scale to measure active upper limb function in hemiparetic patients.
Annals of Physical and Rehabilitation Medicine(2016)
摘要
Objective The Modified Frenchay Scale (MFS) measures active upper limb function in hemiparesis based on a video review of 10 everyday living tasks, each rated on a 10-point visual analogic scale. Six tasks are bimanual and four are unimanual performed with the paretic hand. We measured intra- and inter-rater reliability of MFS in hemiparetic patients among trained raters. Material/patients and methods After a group training session consisting in reviewing and commenting upon ten patient videos, 10 raters assessed the videos of 10 adults with chronic hemiparesis (age 52 ± 13, mean ± SD) on two occasions one week apart. Intra- and inter-rater reliability was assessed using interclass correlation coefficients, mean intra- and inter-rater differences, coefficients of variation between raters and the agreement frequency procedure, agreement being defined as a difference equal or less than 0.5 between two individual ratings. Results For the overall MFS scores, mean intra- and inter-rater ICC coefficients were respectively 0.99 [0.95; 1.00] (mean [95%CI]) and 0.98 [0.98; 1.00]. The mean intra-rater score difference between two ratings one-week apart was 0.26 ± 0.08 and the mean inter-rater standard deviation was 0.61 ± 0.17. Inter-rating differences of less than 0.5 were found in 86% of cases of intra-rater comparisons and in 52% of inter-rater comparisons. Mean inter-rater coefficient of variation was 0.11 ± 0.03. Discussion - conclusion After a group training session in using the scale, the Modified Frenchay Scale has excellent intra- and inter-rater reliability.
