Parkinson's disease (PD) is a neurological disorder which often results in joint rigidity, bradykinesia and decreased range of motion (ROM). Segmental biomechanical muscle stimulation (BMS) can increase ROM in healthy young adults. However, acute effects on ROM in PD have not been examined.
To examine whether BMS and active-assisted cycling (AAC) of the legs results in acute changes in ROM in PD.
Seventeen individuals with PD completed four sessions. Subjects first came to the lab 'on' PD medications and completed baseline assessments. During session 2, subjects were 'off' PD medications and watched a video describing the interventions. In the 3rd and 4th visits, subjects were 'off' medications and the order of AAC or BMS was counterbalanced. Shoulder and hip ROM was measured prior to and immediately after each intervention and hip kinematics were examined during over-ground walking.
There was a significant improvement in hip and shoulder ROM after BMS and AAC. Hip velocity during over-ground walking improved after BMS but not after AAC.
Single bouts of BMS and AAC have a positive effect on ROM and hip velocity during over-ground walking. This suggests that BMS and AAC may be altering central motor control processes.
帕金森病（PD）是一种神经系统疾病，常导致关节僵硬、运动迟缓以及活动范围减小。节段性生物力学肌肉刺激（BMS）可增加健康年轻成年人的活动范围。然而，PD 患者的活动范围的急性影响尚未被检测到。
检验 BMS 和腿部主动辅助循环（AAC）是否会导致 PD 患者的活动范围出现急性变化。
17 名 PD 患者完成了 4 次治疗。受试者首先在服用 PD 药物的情况下来到实验室，并完成基线评估。在第 2 次治疗中，受试者停止服用 PD 药物，并观看一段描述干预措施的视频。在第 3 和第 4 次治疗中，受试者停止服用 PD 药物，并且 AAC 或 BMS 的治疗顺序是平衡的。在每次干预前后测量肩部和臀部的活动范围，并在地面行走时检查髋关节运动学。
BMS 和 AAC 后髋关节和肩部活动范围显著改善。BMS 后地面行走时髋关节速度改善，但 AAC 后无改善。
单次 BMS 和 AAC 治疗对地面行走时的活动范围和髋关节速度有积极影响。这表明 BMS 和 AAC 可能改变了中枢运动控制过程。
