Several measures of isometric contractions reflect motor impairments in subjects with Parkinson's disease (PD), including long relaxation times and greater power in the 5 to 15 Hz electromyographic (EMG) bandwidth during the holding phase of contract

Research on isometric contractions in subjects with Parkinson’s disease (PD) has shown that anti-parkinsonian medication results in a greater increase in extensor strength than flexor strength. This finding is consistent with the hypothesis that th

We studied the effect of high-frequency electrical stimulation of the ventral-intermediate nucleus of the thalamus (Vim) in four patients implanted with chronic stimulators to determine whether this procedure adversely affects reaction time to a prop

Background and Objective: The scientific rationale for pallidotomy as a treatment for PD is that the lesion will reduce excessive tonic inhibition of the thalamus, thereby allowing movement to proceed more normally. If true, then PD patients who move

Studies of rapid, single degree-of-freedom movements have shown different changes in electromyographic patterns for movement tasks that appear very similar (e.g., movements over different ranges of distance). However, it is not clear whether these di

Objective This study evaluated whether changes in the electromygraphic (EMG) pattern during rapid point-to-point movements in individuals diagnosed with PD can: (1) distinguish PD subjects from healthy subjects and (2) determine if differences in the

The conservative strategy proposed by the authors suggests a solution of the degrees-of-freedom problem of the controller. However, several simple motor control tasks cannot be explained by this strategy. A nonconservative strategy, in which more par

When young, healthy subjects perform rapid point-to-point and reversal movements over a range of distances, the patterns of muscle activation associated with accelerating the limb toward the target are modulated in the same way for both movement task
