The use of the treadmill as a gait rehabilitation tool has provided novel options for treatment of gait impairments in Parkinson's Disease (PD). However, the neural mechanisms underlying these therapeutic effects in PD remain unknown and whether any therapeutic effects from treadmill training can be reproduced on overground walking.
To examine the immediate short-term effects of a single session of treadmill and overground walking on gait, spinal and corticospinal parameters in PD.METHODSPD participants (N = 15) were evaluated in two separate sessions under two walking conditions: walking over a treadmill and walking overground. Overground walking performance, the Soleus H-reflex, Reciprocal Ia-Inhibition, Intracortical Facilitation (ICF) and Short Intracortical Inhibition (SICI), were evaluated before and after each condition.
Gait speed and stride length improved in post-treadmill compared with pre-treadmill. No significant changes in these gait parameters were found for the pre vs. post-overground condition. ICF values and Hmax/Mmax ratio decreased after, compared with before, the two walking conditions.
Treadmill walking, but not overground walking, lead to an improvement in the stride length and gait speed in the PD patients without evidence of different modulation on spinal and corticospinal parameters.
跑步机作为一种步态康复工具，为治疗帕金森病（PD）的步态障碍提供了新的选择。然而，其在 PD 中的治疗效果的神经机制尚不清楚，跑步机训练的任何治疗效果是否可以在地面行走中重现。
研究单次跑步机和地面行走对 PD 患者步态、脊髓和皮质脊髓参数的即时短期影响。
将 15 名 PD 参与者分别在两种步行条件下的两个单独的会话中进行评估：在跑步机上行走和在地面上行走。在每种条件之前和之后，评估地面行走性能、比目鱼肌 H 反射、交互 Ia 抑制、皮质内易化 (ICF) 和短皮质内抑制 (SICI)。
与跑步机前相比，跑步机后步态速度和步长提高。在地面条件下，这些步态参数的预与后比较没有显著变化。与两种行走条件之前相比，ICF 值和 Hmax/Mmax 比值在之后降低。
与地面行走相比，跑步机行走可改善 PD 患者的步长和步态速度，而对脊髓和皮质脊髓参数的调节没有明显差异。
