| Objective: To investigate the clinical effect of motor imagery combined with optimized motor skill training in the intervention of upper limb dysfunction after stroke. Methods: A total of 76 patients with post-stroke upper limb dysfunction were divided into control group (n=38) and treatment group (n=38) according to the random number table method. Both groups received routine rehabilitation treatment, the control group received motor imagery training after routine rehabilitation treatment, and the treatment group received motor imagery training combined with optimized exercise skills training on the basis of routine rehabilitation treatment. Before and after treatment, the surface electromyography (sEMG) of the two groups was done to compare the root mean square (RMS) and median frequency (MF) of deltoid, biceps, triceps and extentor carpi of the affected upper limb, and the patients were evaluated by Fugl-Meyer assessment-upper extremities (FMA-UE), Bronze hand test scale (BzH) and Modified barthel index scale (MBI). Results: After 4 weeks of treatment, the RMS and MF of the affected upper limb deltoid, biceps brachii, triceps brachii, extentor carpus in both groups were significantly higher than those before treatment (all P<0.01), and the above indexes in the treatment group were significantly higher than those in the control group (all P<0.01). The scores of FMA, BzH and MBI of the affected limbs in both groups were significantly higher than those before treatment (all P<0.01), and the scores in the treatment group were significantly higher than those in the control group (all P<0.01). Conclusion: Motor imagery combined with optimized motor skill training can improve the sEMG index of upper limb muscle, the function of upper limb and hand, the daily activity ability of patients, and have a significant effect on the dysfunction of upper limb after stroke. |
