八式太极拳对膝骨关节炎不同疼痛反应患者下肢关节负荷影响的回顾性分析
Retrospective Analysis of the Impact of Eight-Form Tai Chi on Lower Limb Joint Load in Patients with Knee Osteoarthritis Showing Different Pain Responses
摘要
Abstract
Objective To explore the impact of eight-form Tai Chi training on lower limb joint load during stair climbing in patients with knee osteoarthritis(KOA)who exhibit different pain responses,and to analyze the reasons for differences in therapeutic effects.Methods A total of 54 KOA patients who completed a 12-week intervention of YANG-style eight-form Tai Chi(60 minutes per session,twice a week)were selected retrospectively.Patients with a reduction ≥1.8 cm in Visual Analogue Scale(VAS)score after the intervention were included in the responder group,while those with a reduction＜1.8 cm were included in the non-responder group.VAS scores of both groups before and after the intervention were compared.A three-dimensional motion analysis system was used to analyze the gait of both groups during stair ascent and descent before and after the intervention,including parameters such as stair ascent/descent speed,maximum muscle torque and torque range of the hip,knee,and ankle joints in three movement planes(sagittal,coronal,and horizontal planes).The total load of the hip,knee,and ankle joints was calculated.Spearman correlation analysis was applied to explore the relationship between the amount of pain change(before and after intervention)and the joint load indicators that showed significant differences before and after the intervention.Results Compared with pre-intervention values within each group,VAS scores of both groups decreased after the inter-vention(P＜0.05 or P＜0.01),and the difference in VAS scores(pre-vs.post-intervention)in the responder group was higher than that in the non-responder group(P＜0.01).In the responder group,stair ascent speed sig-nificantly increased and total hip joint load during stair descent decreased after the intervention compared with pre-intervention(P＜0.05).In the non-responder group,there was no statistically significant difference in stair ascent or descent speed after the intervention(P＞0.05),but the total ankle joint load during stair descent decreased(P＜0.05).The difference in total knee joint load during stair ascent(pre-vs.post-intervention)and the difference in ankle dorsiflexion-plantarflexion muscle torque range during stair descent(pre-vs.post-intervention)in the responder group were both lower than those in the non-responder group(P＜0.05).Correlation analysis showed that the amount of pain change(before and after intervention)was negatively correlated with the change in ankle dorsiflexion-plantarflexion muscle torque range during stair descent(r=-0.346,P＜0.05).Conclusion Eight-form Tai Chi training can improve lower limb joint load in KOA patients,with a more significant impact on knee and ankle joint load in patients who show obvious pain relief.Moreover,the degree of pain relief is closely correlated with the im-provement of ankle joint load.关键词
