Objective To observe the clinical therapeutic effect of extracorporeal shock wave acupoint facilitation technique on shoulder pain in stroke hemiplegia.Methods A total of 60 patients with stroke,hemiplegia and shoulder pain who were admitted to Hebei Rehabilitation Hospital and Qinhuangdao First Hospital from May 2023 to May 2024 were selected as the research subjects.According to the principle of baseline feature matching between groups,the random number table method was used to divide the observation group and the control group,with 30 cases in each group.On the basis of modern conventional rehabilitation training,the patients in the observation group were treated with extracorporeal shock wave acupoint stimulation technology,and the control group was treated with acupressure acupoint stimulation method.The two groups continued to be treated for 6 weeks,and the range of motion,numerical pain and MRC muscle strength of the shoulder joint were measured in all directions before,3 weeks and 6 weeks after treatment,respectively.Results After continuous treatment for 3 and 6 weeks,the range of motion,digital pain measurement,and MRC muscle strength measurement of the shoulder joint in all directions were significantly improved in both groups of patients compared to before treatment(P<0.05);Inter group comparison showed that after treatment,the range of motion,digital pain measurement,and MRC muscle strength measurement of the shoulder joint in the observation group were significantly better than those in the control group,and the differences were statistically significant(P<0.05).Conclusion Extracorporeal shock wave acupoint stimulation technology can effectively improve the problem of hemiplegic shoulder pain in stroke patients,while also enhancing the upper limb motor function of stroke patients.
