Slowness of movement ("bradykinesia") is the most important deficit in Parkinsons disease (PD). Current clinical rating of bradykinesia in PD does not separate the dimensions of slowness and amplitude reduction. We categorized patterns of movement in PD patients on a biaxial classification of speed and amplitude using an electromagnetic tracking device (Polhemus) seeking to determine whether these categories may differentially contribute to motor impairment and disability. Motor impairment was worst in patients with very impaired amplitude and best in patients with normal ...
