摘要
目的 探讨日常佩戴软式支具对慢性踝关节不稳(CAI)患者步行时足底动力学的影响.方法 纳入2021年2月至2023年1月在北京康复医院就诊的单侧CAI患者52例,随机分为对照组(n=26)和试验组(n=26),两组均进行为期8周的运动训练方案,在日常活动中对照组佩戴安慰支具,试验组佩戴踝关节软式支具.采用压力平板系统测量患者步行时的足底峰值压力和足底冲量.结果 对照组脱落6例,试验组脱落5例,最终纳入41例.干预后,对照组各区域足底峰值压力和冲量均无显著性差异(P＞0.05),试验组足跟内侧、外侧和前足内侧区的峰值压力和冲量显著增加(|t|＞4.192,P＜0.001),而中足和前足外侧峰值压力和冲量减小(t＞2.984,P＜0.05);干预后,试验组患侧足跟内侧、外侧和前足内侧区的峰值压力和冲量高于对照组(|t|＞2.126,P＜0.05),中足和前足外侧区峰值压力和冲量低于对照组(t＞2.133,P＜0.05).结论 日常活动中佩戴软式支具可优化CAI患者患侧的足底峰值压力及足底冲量分布,预防再次发生扭伤.
Abstract
Objective To investigate the effect of daily soft brace wearing on plantar dynamics during walking in patients with chronic ankle instability(CAI).Methods A total of 52 patients with unilateral chronic ankle instability(CAI)in Beijing Rehabilitation Hospital from February,2021 to January,2023 were randomly divided into control group(n=26)and experimental group(n=26).Both groups underwent an eight-week exercise training program.The control group wore placebo brace dur-ing daily activities,while the experimental group wore soft ankle brace.Plantar dynamic parameters were mea-sured using a pressure plate system during walking,including peak plantar pressure and plantar impulse before and after intervention.Results Six participants dropped out in the control group and five in the experimental group,resulting in a final inclu-sion of 41 participants.After intervention,there was no significant difference in peak plantar pressure and im-pulse on the affected side in the control group among different areas(P＞0.05).In the experimental group,the peak pressure and impulse in the heel medial,heel lateral and forefoot medial areas increased(|t|＞4.192,P＜0.001),while the peak pressure and impulse in the midfoot and lateral forefoot areas decreased(t＞2.984,P＜0.05);the peak pressure and impulse in the heel medial,heel lateral and forefoot medial areas were higher in the experimental group than in the control group(|t|＞2.126,P＜0.05),and the peak pressure and impulse were low-er in the midfoot and forefoot lateral areas(t＞2.133,P＜0.05).Conclusion Wearing a soft brace during daily activities may optimize the distribution of peak plantar pressure and plan-tar impulse on the affected side in patients with CAI,which may prevent recurrence of sprains.
