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.     «
