Objective To explore the consistency between the iKcare® grading system and Brunnstrom staging in evaluating upper and lower limb motor function in stroke patients. Methods From May 2018 to May 2020, stroke patients who met the standards in 34 medical institutions in China were recruited. The iKcare® grading system and Brunnstrom staging were used to evaluate the motor function of the upper and lower limbs of the subjects, respectively. The Kappa consistency test was used to evaluate the consistency between the two evaluation methods. Results A total of 340 eligible subjects were included, including 230 males and 110 females, with an average age of (61.44±12.77) years old, and an average course of disease of (62.96±42.53) days. The results showed that the Kappa evaluated for upper limb staging was 0.597 (P<0.001), and the Kappa evaluated for lower limb staging was 0.514 (P<0.001). Conclusions The evaluation results of iKcare® grading and Brunnstrom staging have moderate consistency. The iKcare® grading system can be used as an assessment tool for remote rehabilitation of motor function in stroke patients, but there is still room for improvement.
