ABSTRACT
Objective:To investigate the feasibility of movement posture and electromyography based upper-limb motor function assessment system in the assessment of upper-limb motor function for stroke patients. Methods:From January, 2018 to March, 2019, ten stroke patients were recruited from Nanjing Tongren Hospital. According to the predesigned rehabilitation movements, movement posture and surface electromyography data during rehabilitation movement implementation were collected, and the upper-limb motor function of stroke patients were evaluated using movement posture and electromyography based upper-limb motor function assessment system. Further comparisons were also made with single movement posture or electromyography based assessment system. Meanwhile, the validity of the proposed assessment system was verified. All the patients were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE). Results:Positive correlations were shown between movement posture and electromyography based upper-limb motor function assessment system and scores of FMA-UE (r = 0.891, P = 0.001), and better validities were achieved than single movement posture (r = 0.758, P = 0.011) or electromyography (r = 0.697, P = 0.025) based assessment. Conclusion:Movement posture and electromyography based upper-limb motor function assessment system can effectively evaluate the upper-limb motor function of stroke patients.
