PLoS ONE 13(4):Įditor: Manabu Sakakibara, Tokai University, JAPAN This finding suggests that either the kinematic abnormalities were related to processes outside linear corticomuscular communication or PD-related changes in neural correlates maintained corticomuscular communication but not motor performance.Ĭitation: Yoshida T, Masani K, Zabjek K, Popovic MR, Chen R (2018) Dynamic cortical participation during bilateral, cyclical ankle movements: Effects of Parkinson’s disease. However, participants with and without PD did not differ in the magnitude of corticomuscular coherence between the midline cortical areas and tibialis anterior and medial gastrocnemius muscles. Participants with PD exhibited reduced range of motion and more variable bilateral coordination. This movement was performed at a similar cadence to normal walking under two conditions: i) self-paced and ii) externally paced by a metronome. We analyzed electroencephalographic and electromyographic signals from nine men with PD and nine aged-matched healthy men while they sat and cyclically dorsi- and plantarflexed their feet. Here, we aimed to investigate whether kinematic abnormalities are related to cortical participation during bilateral, cyclical ankle movements, which required i) maintenance of a specific frequency and ii) bilateral coordination of the lower limbs in an anti-phasic manner. However, the mechanisms of such abnormalities are not fully understood. Parkinson’s disease (PD) is known to increase asymmetry and variability of bilateral movements.
