| Abstract
|
| [Objective] To observe the effects of radiofrequency acupuncture under ultrasound visual guidance and traditional electro acupuncture on the gait parameters of patients with knee osteoarthritis (KOA) in the early and middle stages,and then to compare with the normal group.[Methods] Sixty knee osteoarthritis patients were randomly divided into radiofrequency group and electro acupuncture group,30 cases in each group. Patients in both groups were treated with massage and traditional Chinese medicine for basic treatment,and functional exercises were instructed once a day. In the RF group,using radiofrequency acupuncture to puncture the meridian lesions around the hip,knee and ankle of the affected limbunder ultrasound visual guidance and choosing 4 to 8 treatment points each time,once a week,for a total of 2 weeks. In the electro acupuncture group,Ashi point,Liangqiu,Xuehai,Neixiyan,Waixiyan,Yanglingquan and Zusanli were selected in the local area of the affected knee. After getting qi,the three groups were connected with the electro acupuncture instrument,20 minutes a day and 6 times a week for 2 weeks. Before and after treatment and one month after treatment,30 normal subjects and two groups of patients were measured gait symmetry,standard degree,average stride length,maximum step height,swing speed,maximum impact force difference,double support phase,landing elevation and ground elevation with dynamic gait and posture analysis system (model:Right Gait Posture-Medical3.0).[Results] After treatment and 1 month after treatment,the symmetry and standard degree of the two groups of patients were better than those before treatment (P<0.05),and the grade distribution of the symmetry and standard degree of the two groups were worse than the normal group (P<0.05). Compared with the electro acupuncture group at the same time,the symmetrical grade distribution of the RF group was better (P<0.05),and the difference in standard grade distribution was not statistically significant (P>0.05). After treatment and 1 month after the treatment,the average stride length,maximum step height,swing speed,ground elevation angle,and ground elevation angle of the two groups of patients were increased by comparing with those before the treatment (P<0.05),and were less than those of the normal group (P<0.05). Compared with the electro acupuncture group at the same time,the average stride length,maximum step height,swing speed,ground elevation angle,and ground elevation angle of the radio frequency group were increased significantly(P<0.05). After treatment and 1 month after the end of treatment,the impact force difference and double support of the two groups of patients were reduced by comparing with the group before treatment(P<0.05),and were greater than those of the normal group (P<0.05). Compared with the electro acupuncture group at the same time,the impact force difference of the radiofrequency group was significantly reduced (P<0.05),and the difference in the dual support phase was not statistically significant (P>0.05).[Conclusion] On the basis of massage,Chinese medicine collapse and functional exercise,ultrasound-guided radiofrequency therapy and traditional electro acupuncture can improve the walking ability of patients with knee osteoarthritis in the early and mid-term and radiofrequency treatment improved more significantly,but the walking ability of the two groups was still worse than the normal group after treatment and 1 month after the treatment. |
