We investigated the characteristics of hip, knee, and ankle joint reaction forces (JRFs) in stroke patients with spastic hemiplegia during sit-to-stand (Si-St) and stand-to-sit (St-Si) movements and explored the relationship between JRFs and joint moments.
Thirteen stroke patients with spastic hemiplegia and thirteen age-matched healthy subjects were recruited in this study. Three-dimensional motion capture system and force plates were employed to collect kinematic data and ground reaction forces during Si-St and St-Si tasks. Musculoskeletal modeling was used to calculate JRFs and joint moments of the hip, knee and ankle joints during these movements.
Those stroke patients exhibited higher JRFs (ranging from 13.49 N/kg to 43.18 N/kg) compared to the healthy group (ranging from 15.81 N/kg to 23.00 N/kg) in hip and knee joints. Furthermore, hip and ankle JRFs exhibited positive correlations with their joint moment in stroke patients during Si-St and St-Si movements.
Early rehabilitation strategies should focus on correcting weight distribution and enhancing symmetry in joint loading. Interventions focused on reducing joint moment, particularly for hip and ankle joints, may prove effective in mitigating lower extremity JRFs in stroke patients with spastic hemiplegia during Si-St and St-Si movements.
我们研究了痉挛性偏瘫中风患者在从坐到站（Si-St）和从站到坐（St-Si）运动过程中髋、膝和踝关节反应力（JRFs）的特征，并探讨了JRFs与关节力矩之间的关系。
本研究招募了13名痉挛性偏瘫中风患者和13名年龄匹配的健康受试者。采用三维运动捕捉系统和测力板在Si-St和St-Si任务期间收集运动学数据和地面反作用力。利用肌肉骨骼模型计算这些运动过程中髋、膝和踝关节的JRFs和关节力矩。
与健康组（范围为15.81 N/kg至23.00 N/kg）相比，那些中风患者在髋关节和膝关节处表现出更高的JRFs（范围为13.49 N/kg至43.18 N/kg）。此外，在Si-St和St-Si运动过程中，中风患者的髋部和踝关节JRFs与其关节力矩呈正相关。
早期康复策略应侧重于纠正体重分布并增强关节负荷的对称性。专注于降低关节力矩的干预措施，尤其是针对髋部和踝关节的措施，可能被证明在减轻痉挛性偏瘫中风患者在Si-St和St-Si运动过程中的下肢JRFs方面是有效的。
