background: stroke is the first cause of morbidity all around the world. entrapment neuropathies are a known complication of stroke. the objective of this study is to assess the frequency of subclinical carpal tunnel syndrome in the healthy and paretic hands of stroke patients. methods: the authors performed nerve conduction study in the first three days after admission in 39 stroke patients wi...

Following a stroke, mirror movements are unintended movements that appear in the non-paretic hand when the paretic hand voluntarily moves. Mirror movements have previously been linked to overactivation of sensorimotor areas in the non-lesioned hemisphere. In this study, we hypothesized that mirror movements might instead have a subcortical origin, and are the by-product of subcortical motor pat...

Increased force variability constitutes a hallmark of arm disabilities following stroke. Force variability is related to the modulation of force below 1 Hz in healthy young and older adults. However, whether the increased force variability observed post stroke is related to the modulation of force below 1 Hz remains unknown. Thus, the purpose of this study was to compare force modulation below ...

OBJECTIVE To investigate whether cutaneous electrical stimulation has a role in the enhancement of sensorimotor function in chronic stroke. SUBJECTS AND SETTING Fifty-nine patients with chronic stroke received cutaneous stimulation during their three-week-long inpatient rehabilitation. Thirty-two received active treatment in the paretic hand and eight received no-current placebo treatment in ...

Stroke survivors' difficulty in releasing grasped objects may be attributable not only to impaired finger extension but also to delays in terminating activity in the gripping flexor muscles. This study was undertaken 1) to quantify the time needed to initiate and terminate grip muscular activity following stroke and 2) to examine effects of arm support, grip location, and active muscle stretch ...

AIM This study aimed to systematically map the severity of mirror movements in both hands in a prospective cohort of children with unilateral cerebral palsy, and to explore the relationship with hand function and brain lesion type. METHOD Seventy-eight children were included (41 males, 37 females; age 9y 4mo, SD 3y 1mo, range 5-15y). Mirror movements were scored during three repetitive tasks ...

Repetitive transcranial magnetic stimulation (rTMS) has recently been demonstrated to improve motor function after stroke. However, no study has yet tested the synergetic effects of physical exercise on rTMS in clinical settings. We investigated the effect of a 6-session course of low frequency rTMS on contralesional primary motor cortex combined with range-of motion (ROM) exercise on paretic h...

In healthy volunteers, reduction of somatosensory input from one hand leads to rapid performance improvements in the other hand. Thus, it is possible that reduction of somatosensory input from the healthy hand can influence motor function in the paretic hand of chronic stroke patients with unilateral hand weakness. To test this hypothesis, we had 13 chronic stroke patients perform motor tasks w...

BACKGROUND AND PURPOSE Mirror movements (MM) are involuntary synchronous movements of one limb during voluntary unilateral movements of the opposite limb. We measured MM in stroke and control subjects and evaluated whether MM after stroke are related to motor function. METHODS Twenty-three patients and 16 control subjects were studied. A computerized dynamometer was used during two squeezing ...
