Abstract

It is important to evaluate body functions and structures, activity, and participation in stroke rehabilitation. The Stroke Impact Scale (SIS), a new stroke-specific self-report measure that was developed by Duncan et al, is widely used to measure multidimensional consequences about health-related quality of life. The SIS version 3.0 includes 9 domains (strength, hand function, activity of daily living and instrumental activity of daily living, mobility, communication, emotion, memory and thinking, participation, and recovery). Patients are asked to make a percentage rating of their recovery since their stroke on a visual analog scale of 0 to 100 for the stroke recovery domain. Each item in the 8 domains other than stroke recovery are scored in a range of 1 to 5 as a raw score and calculated using the manual to a final score. We developed a Japanese version of the SIS version 3.0 and assessed its reliability and validity in 32 chronic stroke survivors. The internal consistency (Cronbachʼs α < 0.70) was satisfactory. The test-retest reliability (ICC, 0.86 to 0.96) was also satisfactory. Regarding convergent validity, a significant correlation (Spearmanʼs correlation coefficient, P < 0.05) was found between the SIS physical domain score and Brunnstrom stage (r, 0.49 to 0.53) and short form 8 (r = 0.82). The Japanese version of the SIS version 3.0 is valid, reliable, and clinically useful for stroke survivors.
