PD: Parkinson’s disease, M: male, F: female, R: right, L: left, MA: most affected, LA: least affected, N: Newton, and LED: levodopa equivalent dose [25]. () Disease rating 1–5 according to Hoehn and Yahr scale. () Unified Parkinson’s disease rating scale, motor section, maximum 108 p. () Rigidity according to UPDRS: 0 = absent; 1 = slight or detectable only when activated by mirror or other movements; 2 = mild to moderate; 3 = marked; 4 = severe. () Total resistance in NeuroFlexor measurements, mean of passive and dynamic condition.
