A comparative study on soleus H reflex parameters using vertebral column and peripheral nerve stimulation
Although low-threshold transcutaneous electrical nerve stimulation (TENS) is a modality used for control of pain, but its effect in the control of spasticity and change of excitability of a motor neuron is controversial. Therefore, this study was conducted to evaluate the effects of 15-min tripolar TENS of vertebral column and bipolar TENS of common peroneal nerve (300 µs width, 50 Hz) on synap...
متن کاملGalvanic vestibular stimulation modifies vection paths in healthy subjects.
The present study aimed at determining whether vestibular inputs contribute to the perception of the direction of self-motion. This question was approached by investigating the effects of binaural bipolar galvanic vestibular stimulation (GVS) on visually induced self-motion (i.e., vection) in healthy subjects. Stationary seated subjects were submitted to optokinetic stimulation inducing either ...
متن کاملSoleus H-reflex to S1 nerve root stimulation.
H-reflexes in normals were elicited by percutaneous electrical and magnetic stimulation of proximal nerve roots at the cauda equina. H-M interval to S1 nerve root stimulation at the level of the S1 foramen was 6.8 +/- 0.33 ms, with side to side difference of 0.16 +/- 0.13 ms. Compression/ischemia of the sciatic nerve in the mid-thigh abolished the H-reflex to stimulation of the tibial nerve at ...
متن کاملGalvanic vestibular stimulation in hemi-spatial neglect
Hemi-spatial neglect is an attentional disorder in which the sufferer fails to acknowledge or respond to stimuli appearing in contralesional space. In recent years, it has become clear that a measurable reduction in contralesional neglect can occur during galvanic vestibular stimulation, a technique by which transmastoid, small amplitude current induces lateral, attentional shifts via asymmetri...
متن کاملFunctional MRI of galvanic vestibular stimulation.
The cortical processing of vestibular information is not hierarchically organized as the processing of signals in the visual and auditory modalities. Anatomic and electrophysiological studies in the monkey revealed the existence of multiple interconnected areas in which vestibular signals converge with visual and/or somatosensory inputs. Although recent functional imaging studies using caloric ...
