Objectives: Stroke is the leading cause of long-term disability. Hand motor impairment resulting from chronic stroke may have extensive physical, psychological, financial, and social implications despite available rehabilitative treatments. The best time to start treatment for stroke, is in sub-acute period. Repetitive transcranial magnetic stimulation (rTMS) is a method of stimulating and ...

Force tracking using fine motor control with simultaneous cognitive dual tasking may provide a useful measure of disease progression in Parkinson’s disease (PD). Due to the challenging nature of the task, measures from this task may be useful in documenting changes in the progression of the disease especially since such changes are subtle in nature early on in the disease process. We have descr...

Previous studies have suggested that the left and right hands have different specialties for motor control that can be represented as two agents in the brain. This study examined how coordinated movements are performed during bimanual reaching tasks to highlight differences in the characteristics of the hands. We examined motor movement accuracy, reaction time, and movement time in right-handed...

Hyperbaric oxygen (HBO2) therapy for children with cerebral palsy (CP) is not new. Research documenting the effects in this population has been anecdotal. We evaluated the effects of HBO2 therapy for 25 children (X = 5.6 +/- 1.6 yr) with a functional diagnosis of spastic diplegic CP. Pre- and post-HBO2 evaluations consisted of the following measures: gross motor function measure (GMFM), fine mo...

Cold ambient temperature conditions are known to affect muscle performance characteristics, such as force output, power, and contraction velocity [ 11. Spectral and aniplitude characteristics of electromyogram (EMG) during inuscle contraction are modulated by the cold and hot ambient temperature [2]. Voluntary control of single motor unit action potentials (MUM') is a widely used method for inv...

A profile of progressive neurological symptoms referred to collectively as HIV-associated neurocognitive disorder (HAND) has been found to be linked to human immunodeficiency virus type 1 (HIV1) with symptoms implicating several cognitive domains, including attention, learning, memory, affect and motor functioning [1-3]. Neuropsychological testing indicates that around fifty percent of HIV pati...

Recent work has shown that the primate reticulospinal tract can influence spinal interneurons and motoneurons involved in control of the hand. However, demonstrating connectivity does not reveal whether reticular outputs are modulated during the control of different types of hand movement. Here, we investigated how single unit discharge in the pontomedullary reticular formation (PMRF) modulated...
