Reliability and validity of the Chinese version of the stroke upper limb capacity scale

To evaluate the reliability and validity of the Chinese version of the Stroke Upper Limb Capacity Scale (SULCS) compared to the Wolf Motor Function Test (WMFT) and the Fugl-Meyer Assessment-Upper Extremity (FMA-UE). Patients with hemiplegia after stroke (n = 60). The intraclass correlation coefficient (ICC) and corresponding 95% confidence intervals (CI) were used to explore the reliability, and Spearman’s correlation coefficient was used to analyze validity. Floor and ceiling effects were counted. The ICCs for inter-rater reliability and intra-rater reliability were ICC = 0.985 (95%CI = 0.966–0.992) and ICC = 0.982 (95%CI = 0.970–0.989), respectively. The SULCS demonstrated a strong correlation with the WMFT (r = 0.922, p r = 0.921, p r = 0.946, p r = 0.952, p r = 0.745, p r = 0.768, p Our analysis of the psychometric properties supports the use of the Chinese version of the SULCS to measure upper limb capacity in patients with hemiplegia after stroke. StrokeThe Chinese version of Stroke Upper Limb Capacity Scale (SULCS) is a valid and reliable tool to assess the capacity of the upper extremity in patients with stroke.The instructions of SULCS are easy to understand and implement, and notably elderly patients, those with aphasia, and individuals with mild cognitive impairment can also follow the tasks.The SULCS is an easy-to-use and feasible scale that is recommended for clinical and study purposes.
