摘要

运动训练通常作为药物治疗的辅助手段来改善帕金森病患者的体位不稳定性。由于在这一人群中尚未建立运动剂量与相应的姿势稳定性影响之间的关联,因此我们在本研究中旨在探讨这一主题。这是一项探索性研究,于2011年6月至2013年6月在香港理工大学步态与平衡实验室进行。符合条件的帕金森病患者(n = 51)被随机分配到平衡和步态训练组或力量训练组。为期12周的培训包括两个为期4周的物理治疗师监督的实验室培训阶段,以及为期4周的自我监督的家庭培训阶段。在基线和每个训练阶段结束后,盲法测试者使用极限稳定性测试、单腿站立测试、步行测试和特定活动平衡置信度量表来检查姿势稳定性。基线评估显示平衡和步态训练组与力量训练组之间没有显著差异。在平衡和步态训练组中,第一个4周的训练期显著改善了大多数平衡和步态表现(P < 0.025),第12周的训练期进一步改善了步态速度和特定活动平衡信心量表得分。在力量训练组中,第一个4周的训练阶段显著改善了稳定性测试和步态速度极限的终点偏移,第12周的训练阶段改善了步行测试中的单腿站立时间和步幅。所有的改进都发生在以实验室为基础的培训期间。因此,在帕金森病患者中,4周的平衡和步态训练可以改善姿势稳定性,而需要更长的时间进行力量训练才能获得类似的改善。

Dose-response characteristics of exercise training in individuals with Parkinson's disease: an exploratory study
Exercise training is often prescribed as an adjunct to medication to improve postural instability in individuals with Parkinson’s disease. As the association between exercise dose and the corresponding effects on postural stability has not been established in this population, we aimed to explore this topic in the present study. This is an exploratory study conducted in the Gait and Balance Laboratory at the Hong Kong Polytechnic University in a period from June 2011 to June 2013. Eligible participants with Parkinson’s disease (n = 51) were randomly assigned to either a balance and gait training group or a strength training group. The 12-week training period included two 4-week phases of physiotherapist-supervised laboratory-based training separated by a 4-week phase of self-supervised home-based training. Blinded testers examined postural stability using the limit of stability test, single-leg-stance test, walking test, and the activities-specific balance confidence scale, at baseline and after each training phase. Baseline evaluations revealed no significant difference between the balance and gait training and strength training groups. In the balance and gait training group, the first 4-week training phase led to significant improvement in most measures of balance and gait performance (P < 0.025), and the 12-week training phase yielded further improvements in gait velocity and activities-specific balance confidence scale score. In the strength training group, the first 4-week training phase led to significant improvement in the endpoint excursion in the limit of stability test and gait velocity, and the 12-week training phase resulted in an improvement in the single-leg-stance time and stride length in the walking test. All improvements occurred during the laboratory-based training sessions. Therefore, in individuals with Parkinson’s disease, a 4-week period of balance and gait training could improve postural stability, whereas longer durations of strength training are required to gain comparable improvements.
