摘要

Objective: To investigate the predictive validity, responsiveness, and minimally clinically important difference of arm accelerometer in real-world activity of patients with chronic stroke.

Design: Validation and psychometric study.

Results: 82 subjects were recruited in the study (mean age: 55.32; mean score of Fugl-Meyer Assessment: 39.91). Correlations between the arm accelerometer and 3 clinical measurement tools were fair to moderate (Pearson r = 0.47, 0.42, and 0.34, respectively). The correlation between the arm accelerometer and the quality of use of Motor Activity Log subscale was moderate to good (Pearson r = 0.57). The responsiveness of the arm accelerometer from pretreatment to posttreatment was medium (standardized response mean = 0.72). The minimally clinically important difference range for the arm accelerometer was 547 to 751 mean counts.

Conclusions: The arm accelerometer demonstrated acceptable predictive validity and responsiveness in patients with chronic stroke. The affected arm activity measured by the arm accelerometer was sensitive to change. The change score of a patient with chronic stroke on the arm accelerometer should reach 574 to 751 mean counts to be regarded as a minimally clinically important difference.
