Clinical effect of motor imagery therapy on upper limb motor dysfunction after stroke

Abstract

Objective To investigate the clinical effect of motor imagery therapy on upper limb motor dysfunction in stroke patients. Methods 120 patients with post stroke upper limb disability were selected.According to the digital table, they were divided into observation group and control group, 60 cases in each group.Two groups were treated with primary disease and rehabilitation treatment, the observation group used motor imagery therapy, the two groups were treated for 3 months.Limb simplified Fugl-Meyer rating scale(FMA) and self-care ability Barthel index(MBI) were used to evaluate the motor function and self-care ability of the patients before and after treatment.The upper limb movement was evaluated by ARAT before and after treatment.The quality of life score before and after treatment was observed. Results Before treatment, there were no statistically significant differences in FMA and BI scores between the two groups(t=0.13, 0.23, all P>0.05). After treatment, the FMA score of the control group was (29.74±4.04)points, the BI score was (57.29±4.23)points, the FMA and BI scores of the observation group was (33.29±4.14)points, (63.12±4.21)points, respectively, the differences were statistically significant between before and after treatment in the self-group(t=3.56, 5.61, all P<0.05), and the degree of elevation of the observation group was more significant than those of the control group, the differences were statistically significant(t=2.38, 4.14, all P<0.05). After treatment, the degrees of elevation of the scores of ARAT in the observation group[grab (13.34±2.00)points, grip (10.23±0.39)points, pinch (14.53±1.43)points, thick (8.20±0.42)points]were significantly higher than those in the control group, the differences were statistically significant(t=3.45, 2.87, 3.17, 2.98, all P<0.05). After treatment, the rise degree of the scores of quality of life in the observation group[physiological field (68.71±6.62)points, psychological field (69.02±6.38)points, social relations (67.72±6.79)points, environmental field (70.72±6.98)points]were higher than those in the control group, the differences were statistically significant(t=4.23, 3.98, 3.23, 2.98, all P<0.05). Conclusion The effect of exercise therapy on the upper limb of patients after stroke has significantly clinical efficacy, and it can help patients to restore limb motor function, improve self-care ability and quality of life, it is safe and worthy of clinical promotion.
