Nordic Walking Improves Gait Power Profiles at the Knee Joint in Parkinson's Disease

摘要

We investigated the impact of Nordic walking (NW) on gait patterns in individuals with Parkinson's disease (PD) following a 6-week NW familiarization. Twelve participants with PD and 12 healthy older adults took part in a gait analysis walking with and without poles (NP). Results showed larger knee power (knee extensor: K2) on the most affected leg in NW compared to NP (P = .01). On the less affected side, larger power absorption (knee extensor: K3) was found during preswing (K3) compared to older adults in both NP and NW (P = 0.01). NW showed longer stride length and single support time (P .01) compared to NP. Walking with poles improved gait spatial-temporal characteristics and power profiles at the knee joint both on the less and most affected sides in individuals with PD. NW could be beneficial to help regain a more functional gait pattern in PD.
