Declines in postural control, mobility, and gait are related to negative health outcomes in Parkinson's disease (PD). The addition of small weights to the trunk has been used to increase postural stability and functional performance in persons with neurological dysfunctions but not in persons with PD. The purpose of the study was to determine if small weights applied on the torso have immediate effects on balance and mobility in people with PD.
Randomized controlled clinical trial.
Forty-two subjects with PD were randomly assigned to a no weight (NW), fixed weight (FW), and variable weight (VW) placement group. Outcome measures included the instrumented modified clinical test of sensory interaction in balance (mCTSIB), Tinetti Performance Oriented Mobility Assessment (POMA), timed up and go (TUG), modified timed up and go (mTUG), functional reach test (FRT), 360° turns, 10-meter walk test (10MWT), and lower extremity strength. These measures were performed at baseline and after group assignment. Weights approximately 1-1.5% of the participant's body weight were attached to the trunk using a vest garment according to group assignment. Post-testing was performed immediately after application of weights, using the same outcome measures as the pre-test. Analysis of covariance (ANCOVA) and post hoc tests were used to determine the group with the most statistically significant improvement.
The VW group showed significant improvement in the 10-meter walk compared with the NW group (p=0.039) and the FW group (p=0.008). All other outcome measures did not reach significant differences between all groups.
Strategic trunk weighting has the potential to improve mobility and balance in a sample of individuals with PD. The findings support existing literature on the positive effects of torso weighting. A treatment that includes the addition of small weights on the torso is a promising intervention that may improve balance and mobility.
姿势控制、移动和步态的下降与帕金森病（PD）的负面健康结果有关。在患有神经功能障碍的人群中，已经使用在躯干上添加小重量的方法来提高姿势稳定性和功能表现，但在 PD 患者中尚未使用。本研究的目的是确定在 PD 患者中，将小重量施加在躯干上是否对平衡和移动能力有直接影响。
随机对照临床试验。
42 名 PD 患者被随机分配到无重量（NW）、固定重量（FW）和可变重量（VW）放置组。结果测量包括仪器化改良临床感觉互动平衡测试（mCTSIB）、Tinetti 表现导向移动评估（POMA）、计时起立行走测试（TUG）、改良计时起立行走测试（mTUG）、功能伸手测试（FRT）、360°转弯、10 米步行测试（10MWT）和下肢力量。这些测量在基线和分组后进行。根据分组，使用背心服装将大约参与者体重的 1-1.5%的重量附加到躯干上。测试后立即在应用重量后进行，使用与预测试相同的结果测量。使用协方差分析（ANCOVA）和事后检验来确定具有最显著统计学改善的组。
VW 组与 NW 组（p=0.039）和 FW 组（p=0.008）相比，10 米步行测试有显著改善。所有其他结果测量在所有组之间均未达到显著差异。
躯干策略性加权有可能改善 PD 患者样本的移动性和平衡。这些发现支持关于躯干加权的积极影响的现有文献。包括在躯干上添加小重量的治疗方法是一种很有前途的干预措施，可能会改善平衡和移动能力。
