Facilitation of cutaneous inputs during the planning phase of gait initiation.
It has been shown that during the planning of a voluntary movement the transmission of cutaneous afferent inputs to the somatosensory cortex is attenuated shortly before the motor output as well as during movement execution. However, it is not known whether the sensory suppression observed during the planning phase (i.e., before any movement execution) is a systemic phenomenon or whether it is ...
متن کاملCutaneous electrical stimulation may enhance sensorimotor recovery in chronic stroke.
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 ...
متن کاملImpaired transmission in the corticospinal tract and gait disability in spinal cord injured 1 persons 2 3
32 33 Rehabilitation following spinal cord injury is likely to depend on recovery of 34 corticospinal systems. Here we investigate whether transmission in the corticospinal tract 35 may explain foot drop (inability to dorsiflex ankle) in persons with spinal cord lesion. 36 The study was performed in 24 persons with incomplete spinal cord lesion (C1 to L1) and 37 15 healthy controls. Coherence i...

متن کاملCutaneous stimulation of discrete regions of the sole during locomotion produces “sensory steering” of the foot
BACKGROUND While the neural and mechanical effects of whole nerve cutaneous stimulation on human locomotion have been previously studied, there is less information about effects evoked by activation of discrete skin regions on the sole of the foot. Electrical stimulation of discrete foot regions evokes position-modulated patterns of cutaneous reflexes in muscles acting at the ankle during stand...
