| Objective: To investigate the effects of EMG biofeedback combined with graded motor imagery on upper limb motor function in stroke patients.
Methods: In this study, 45 stroke inpatients who met the inclusion criteria and attended the Xi'an Trade Union Hospital between December 2023 and July 2024 were selected as the study subjects, and were divided into the conventional group (n=15), the myoelectric feedback group (n=15), and the combined group (n=15) by using the random number table method; each group was intervened for 6 consecutive weeks, 5 times a week, and before and after the treatment, they were treated with the Brunnstrom upper extremity, Fugl-Meyer upper extremity motor function (FMA-UE), box block test (BBT), and modified Barthel index (MBI) to assess the intervention effect.
RESULTS: After treatment, the Brunnstrom upper extremity staging, FMA-UE score, BBT score, and MBI score of the three groups of patients were significantly improved compared with those of the pre-treatment group (P < 0.05); the combined group showed more significant improvement than the conventional group in Brunnstrom upper extremity staging, FMA-UE score, and BBT score (P < 0.05), and the combined group showed more significant improvement than the myoelectric feedback The combined group also showed significant improvement in FMA-UE score (P<0.05), and the MBI scores of patients in the three groups showed significant improvement compared with the pre-treatment period (P<0.05), but there was no significant difference in the comparison between the groups (P>0.05).
Conclusion: Compared with EMG biofeedback, EMG biofeedback combined with graded motor imagery can further improve upper limb motor function in stroke patients. |
