背景。 Orle 需要进一步阐述的研究领域是损伤与功能限制之间的关系。通过识别功能限制的具体因素，可以制定干预策略，包括运动方法，以延缓或改善功能下降。脊柱灵活性受损与功能限制之间的关联尚未得到深入研究。本研究的目的是确定 (a) 脊柱灵活性和功能限制之间的关联； (b) 脊柱灵活性对特定功能限制的相对贡献； (c) 疾病状态（帕金森病 [PD] 与无 PD）如何改变这些关系。方法。参与者包括 251 名社区居民，其中 56 人患有帕金森病，195 人没有患帕金森病或其他特定疾病。测量包括脊柱灵活性（即功能性轴向旋转 [FAR]）和配置（即胸椎后凸和腰椎前凸）、功能限制（即功能范围、仰卧站立时间、10 米墙和 360 度转动）。结果，规范相关性 (Can R) 证明脊柱测量值和功能限制 (Can R) 之间存在显着关联 =.488 p =.0001)。在控制了年龄、性别、种族、体重指数、合并症、自信心和抑郁后，多元回归模型表明，脊柱灵活性对功能范围有显着贡献（整个模型的 R-2 = .334，（p = .0001）。根据 0.026 的参数估计值，结果预测 FAR 导致最不灵活的参与者和最灵活的参与者之间的到达距离存在 4.6 英寸的差异。此外， 与非 PD 参与者相比，PD 的几乎所有测量值之间存在差异。结论。结果清楚地表明脊柱灵活性是功能达到的一个因素、功能限制的衡量标准和平衡控制的既定衡量标准。需要进一步的工作来确定脊柱灵活性可以改善的程度以及改善对平衡的影响。
Background. Orle area of research that requires further elaboration is the relationship between impairments and functional limitations. By identifying specific contributors to Functional limitations, it may be possible to establish intervention strategies, including exercise approaches, that can delay or ameliorate decline in function. The association between impaired spinal flexibility and functional limitations has nor been studied in depth. The purposes of this study were to determine (a) the associations between spinal flexibility and functional limitations; (b) the relative contribution of spinal flexibility to specific functional limitations; and (c) how disease state (Parkinson's disease [PD] vs no PD) modified these relationships.Methods. participants included 251 community-dwelling adults, 56 of whom were with diagnosed PD and 195 were without PD or other specific disorders. Measures included spinal flexibility (i.e., functional axial rotation [FAR]) and configuration (i.e., thoracic kyphosis and lumbar lordosis), functional limitations (i.e., functional reach. supine-to-stand time, 10-m wall;, and 360 degrees turn).Results, Canonical correlation (Can R) demonstrated significant associations between spinal measures and functional limitations (Can R =.488 p =.0001). After controlling for age, gender, race, body mass index, comorbidity, confidence, and depression, a multivariate regression model demonstrated that spinal flexibility contributed significantly to functional reach (R-2 =.334 for the overall model, (p =.0001). Based on the parameter estimate of 0.026, the results predict that FAR accounts for a 4.6-inch difference in reach distance between the least and most flexible of the participants. In addition, there were significant differences between almost all measurements for the PD compared with the non-PD participants.Conclusion. Results clearly implicate spinal flexibility as a contributor to functional reach, a measure of functional limitation and an established measure of balance control. Further work is needed to determine the extent to which spinal flexibility can be improved and the effect of that improvement on balance.
