Tai Chi is an available method for the treatment of knee osteoarthritis (KOA). The impacts of Tai Chi on plantar loads of individuals with KOA are not fully understood. 46 participants with knee osteoarthritis were randomly assigned into the Tai Chi group ( = 23) or the control group ( = 23). The Tai Chi group attended a 6-month Tai Chi program, and the control group participated in a wellness education program. Novel Pedar-X system was used to collect the peak pressure (PP) and maximum force (MF) during walking before and 6 months after the intervention. Significant higher peak pressure and maximum force were observed in the 4th and 5th metatarsophalangeal joints in the Tai Chi group. However, there were significant declines in the peak pressure of the whole foot and the 2nd and 3rd metatarsophalangeal joints and maximum force of the heel in the control group. These results suggested that individuals with KOA might change the pattern of plantar loads during walking through Tai Chi, and plantar loads would be useful as a parameter to assess the effect of Tai Chi on knee osteoarthritis. This trial is registered with Clinical Trials: CHiCTR-TRC-13003264.
太极拳是治疗膝骨关节炎(KOA)的一种可行方法。太极拳对 KOA 患者足底负荷的影响尚不完全清楚。46 名膝骨关节炎患者被随机分为太极拳组(n=23)和对照组(n=23)。太极拳组参加了为期 6 个月的太极拳课程,对照组参加了健康教育培训课程。使用 Novel Pedar-X 系统在干预前和干预后 6 个月收集行走时的峰值压力(PP)和最大力(MF)。在第 4 和第 5 跖骨趾关节中,太极拳组的峰值压力和最大力显著升高。然而,对照组的整个足部、第 2 和第 3 跖骨趾关节的峰值压力和跟骨的最大力显著下降。这些结果表明,KOA 患者可能通过太极拳改变行走时的足底负荷模式,足底负荷可以作为评估太极拳对膝骨关节炎影响的参数。本试验已在临床试验注册:CHiCTR-TRC-13003264。
