[Purpose] Individuals with Parkinson's disease (PD) experience postural dysfunction, which can contribute to pain and an increased risk for falls. One method with limited research for addressing postural dysfunction is bracing. The objective of this pilot study was to establish the immediate impact of a novel thoracolumbar brace on postural alignment in individuals with PD. [Participants and Methods] This study utilized a single-participant randomized A-B design. Participants were included if they had a diagnosis of PD were 50-80 years of age, reported difficulty with posture, but were able to ambulate within their home and the community. Ten kinematic assessments of posture were completed in each phase. The primary outcome measure was postural alignment at the neck, trunk, and hip/knee. An analysis of postural stability and experience wearing the brace was also completed. [Results] Nine out of ten participants demonstrated at least one statistically significant change in a posture variable, but postural stability was variable across participants. [Conclusion] This pilot study demonstrated that the brace functioned as expected bringing postural alignment into a more neutral or extended position at the trunk and hip/knee. Further research on the long-term effect of the brace needs to be completed to determine its clinical value.
[目的]帕金森病（PD）患者存在姿势功能障碍，这可能导致疼痛并增加跌倒风险。一种用于解决姿势功能障碍但研究有限的方法是使用支具。这项初步研究的目的是确定一种新型胸腰椎支具对PD患者姿势 alignment 的即时影响。[参与者与方法]本研究采用单参与者随机A - B设计。参与者纳入标准为年龄在50 - 80岁，诊断为PD，报告有姿势困难，但能够在家中和社区内行走。每个阶段完成十次姿势运动学评估。主要结局指标是颈部、躯干和髋部/膝部的姿势 alignment。还完成了姿势稳定性分析以及佩戴支具的体验。[结果]十名参与者中有九名在姿势变量上至少有一项具有统计学意义的变化，但参与者之间的姿势稳定性各不相同。[结论]这项初步研究表明，支具按预期发挥作用，使躯干和髋部/膝部的姿势 alignment 进入更中立或伸展的位置。需要完成关于支具长期效果的进一步研究以确定其临床价值。
