Neurodegenerative processes in Parkinson's disease (PD) particularly affect activities of daily living (ADL). Problems of patients with PD in sit-to-stand (STS) performance have been verified before, but not the effects of training on biomechanical measures of STS function. This pilot study aimed to analyse effects of 12 weeks of Nordic Walking training and severity of PD: healthy controls (CO), least (UPDRS A) and more severe (UPDRS B) affected PA on selected functional outcome measures. We expected improvements in PD similar to CO, with better performance of the unstable second phase and faster execution of the entire movement with higher velocities of centre of gravity (COG). 3D kinematics of 22 PD and 18 CO subjects before and after training, were recorded using a motion analysis system (Vicon, Oxford). We compared five outcome measures for STS in 11 PD and 11 CO, matched according to age, gender, height, and weight. Effects of Nordic Walking training were not statistically significant but indicated different patterns which depended on the values of patient's UPDRS score (part III, motor functions). Time required for STS performance increased and horizontal and vertical velocity of COG decreased in UPDRS B, which could be due to progression of PD during the training period. In contrast, UPDRS A showed similar effects as CO. The effects of Nordic Walking as an easy, economic and low-risk intervention on STS in PD depend on the degree of PD. Our findings may help scientists, patients, and therapists to adjust sport-physiological interventions.
帕金森病 (PD) 的神经退行性过程尤其会影响日常生活活动 (ADL)。已经证实 PD 患者在从坐到站 (STS) 表现方面存在问题，但关于训练对 STS 功能生物力学测量的影响还没有研究。本研究旨在分析 12 周北欧行走训练和 PD 严重程度对所选功能结果测量的影响：健康对照组 (CO)、最轻微 (UPDRS A) 和更严重 (UPDRS B) 影响的 PA。我们期望 PD 患者能取得与 CO 相似的改善，在不稳定的第二阶段表现更好，整个运动的执行速度更快，重心 (COG) 的速度更高。在训练前后，使用运动分析系统 (Vicon，牛津) 记录了 22 名 PD 和 18 名 CO 患者的 22 名 PD 和 18 名 CO 患者的 3D 运动学。我们比较了 11 名 PD 和 11 名 CO 患者的 5 项 STS 结果测量值，这些测量值根据年龄、性别、身高和体重进行匹配。北欧行走训练的效果不具有统计学意义，但表明了不同的模式，这取决于患者 UPDRS 评分 (第三部分，运动功能) 的值。在 UPDRS B 中，STS 表现所需的时间增加，COG 的水平和垂直速度降低，这可能是由于在训练期间 PD 的进展。相比之下，UPDRS A 表现出与 CO 相似的效果。北欧行走作为一种简单、经济、低风险的干预措施，对 PD 患者 STS 的影响取决于 PD 的严重程度。我们的发现可以帮助科学家、患者和治疗师调整运动生理学干预措施。
