Abstract: Objective: To observe the clinical effect of balance needle therapy combined with task-oriented training for upper limb functional disorder in post-stroke patients. Methods:A total of 121 post-stroke patients with upper limb functional disorder treated at Zhumadian Central Hospital from January 2022 to December 2023 were randomly divided into the control group (61 cases) and the observation group (60 cases) by a random number table method. Both groups received routine rehabilitation training. The control group additionally underwent task-oriented training,while the observation group received balance needle therapy based on the treatment of the control group. Both groups were intervened for six weeks. The clinical effects,biomechanical indicators of the affected upper limb,motor function [simplified Fugl-Meyer Assessment scale (FMA) score],proprioception [average trajectory error(ATE)],and activities of daily living [modified Barthel Index (MBI) ] were compared between the two groups. Results: After six weeks of intervention,the total effective rate was 94.23%( 49/52) in the observation group,which was higher than that of 80.77%( 42/52) in the control group( P<0.05). Both groups showed increased peak torque( PT), total work( TW), and average power( AP) on the affected side elbow extensors and flexor than those observed before intervention,and the observation group had greater PT,TW,and AP than the control group (P<0.05). Both groups showed an increase in FMA scores than that observed before intervention, with the observation group having a higher FMA score than the control group (P<0.05). Both groups showed a decrease in ATE than that observed before intervention on the affected side,with the observation group having a lower ATE than the control group (P<0.05). Both groups showed an increase in MBI scores than that observed before intervention, with the observation group having a higher MBI score than the control group (P<0.05). Conclusion: The combination of balance needle therapy and task-oriented training effectively enhances upper limb muscle strength, motor function, proprioception, and activities of daily living in stroke patients.
