To compare the effects of Tai Chi and balance and postural control training on spatiotemporal parameters and dual-task costs during stair negotiation in knee osteoarthritis participants.
Sixty-nine knee osteoarthritis participants were randomly assigned to either the Tai Chi group or the balance and postural control training group. All participants underwent interventions twice a week for 12 weeks. Pain scores, spatiotemporal parameters and dual-task costs during stair ascent and descent were measured before and after the intervention.
Both groups reported significant reductions in pain and improvements in spatiotemporal parameters following the intervention. The Tai Chi group exhibited a significantly greater reduction in initial double stance time during stair descent compared with the balance and posture control training group under both single-task (F = 8.177, p = 0.006, η = 0.143) and dual-task (F = 5.007, p = 0.03, η = 0.093) conditions. Meanwhile, the balance and posture control training group showed significant reductions in the dual-task cost values of cadence (p = 0.003) and speed (p = 0.038), although no significant between-group differences were observed.
Both Tai Chi and balance and postural control training alleviated pain and improved spatiotemporal parameters during stair negotiation in participants with knee osteoarthritis. However, improvements in dual-task cost of cadence and speed were limited, potentially due to insufficient intervention or gait strategy adaptations. Only the balance and postural control group showed a significant reduction in dual-task cost during stair descent, indicating its advantage in maintaining stability under cognitive load.

比较太极拳与平衡及姿势控制训练对膝骨关节炎患者上下楼梯时时空参数和双重任务成本的影响。
69名膝骨关节炎患者被随机分为太极拳组或平衡及姿势控制训练组。所有参与者每周接受两次干预，共12周。在干预前后测量上下楼梯时的疼痛评分、时空参数和双重任务成本。
两组在干预后疼痛均显著减轻，时空参数均有改善。在单任务（F = 8.177，p = 0.006，η = 0.143）和双重任务（F = 5.007，p = 0.03，η = 0.093）条件下，太极拳组在下楼梯时的初始双支撑时间相比平衡及姿势控制训练组均有显著更大幅度的减少。同时，平衡及姿势控制训练组的步频（p = 0.003）和速度（p = 0.038）双重任务成本值显著降低，尽管组间未观察到显著差异。
太极拳与平衡及姿势控制训练均能减轻膝骨关节炎患者上下楼梯时的疼痛并改善时空参数。然而，步频和速度的双重任务成本改善有限，可能是由于干预不足或步态策略适应不够。只有平衡及姿势控制组在下楼梯时的双重任务成本显著降低，表明其在认知负荷下维持稳定性方面具有优势。
