Clinical Observation On The Rehabilitation Effect Of Repetitive Transcranial Magnetic Stimulation In Convalescent Stroke Patients With Knee Hyperextension

Objective: To observe the clinical efficacy of repetitive transcranial magnetic stimulation(r TMS)technique on knee hyperextension in patients recovering from stroke.Methods: Sixty-four patients with recovered stroke who were admitted to the rehabilitation ward and neurology department of Jiangbin Hospital of Guangxi Zhuang Autonomous Region from March 2021 to March 2022 and met the inclusion criteria were selected and divided into two groups using a randomized method,with 32 cases in each group.Both groups received basic treatment,i.e.,pharmacotherapy.The control group was treated with conventional rehabilitation therapy,while the observation group was treated with r TMS on the basis of the control group,and the patients were evaluated before and after treatment with knee hyperextension in the standing position with weight on one leg,the number of knee hyperextensions in the 50 m walk,the "get up-walk" timing test,the FMA score,the BBS score,etc.The clinical results of the two groups were compared after 4 weeks of treatment.Results: There was no statistical difference in the basic information of the two groups before treatment.The differences were not statistically significant(P>0.05).Evaluation of the efficacy of knee hyperextension in the standing position with weight on one leg: After treatment,there was a significant difference between the two groups compared with the pre-treatment index(P<0.05),and the experimental group showed a statistically significant improvement compared with the control group(P<0.05).The difference was statistically significant(P<0.05);and the experimental group improved more significantly than the control group,and the difference was statistically significant(P<0.05)."Stand-up-walk" timing test: After treatment,the patients’ "stand-up-walk" time was significantly reduced in both groups compared with that before treatment,and the difference was statistically significant(P<0.05);and the improvement in the experimental group was more obvious than that in the control group,and the difference was statistically significant(P<0.05).FMA score and BBS score: After treatment,the FMA(Fugl-Meyer Assessment motor function assessment)score and BBS(Berg balance scale balance function scale)score of patients in both groups increased significantly compared with those before treatment,and the difference was statistically significant(P<0.05);and the experimental group improved more significantly than the control group,and the difference was statistically significant(P<0.05).The difference was statistically significant(P<0.05).Conclusion: r TMS is effective in restoring knee hyperextension and motor function in recovering stroke patients,and the combination of conventional rehabilitation therapy with r TMS significantly reduces the number of knee hyperextensions in stroke patients with single-leg weight-bearing and 50 m walking.The combination of the two can better restore the movement and balance of the lower limbs of such patients and provide scientific experimental data and theoretical basis,which is of high clinical value to promote the better and faster development of modern rehabilitation medicine.
