Abstract
It is not known yet whether spontaneous sway in quiet stance is somehow abnormal in people with early Parkinson’s Disease (PD). Furthermore, it is not known if sway measures show changes that are correlated with the disease progression early in the disease process. Jerk, that is the rate of change of the acceleration, has been used in motor control studies to quantify smoothness of movement [1]. We hypothesize that jerk of trunk sway may be altered in early PD, and could provide a sensitive measure of disease progression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
