简介：
Overview
This protocol allows for the neurophysiologic assessment of the lower extremity corticospinal tract post-stroke when gait and balance are of primary interest. The technique increases the probability of eliciting a motor evoked potential in individuals who may not show a resting response.
Key Study Components
Area of Science
- Neurophysiology
- Stroke Rehabilitation
- Motor Control
Background
- Assessment of lower extremity muscles is crucial for post-stroke recovery.
- Transcranial magnetic stimulation (TMS) is a non-invasive method used to evaluate corticospinal tract function.
- Standing position during assessment enhances response probability.
- Many post-stroke patients do not exhibit a resting response, complicating assessments.
Purpose of Study
- To evaluate neurophysiological responses in lower extremity muscles.
- To improve assessment techniques for post-stroke patients.
- To facilitate better understanding of gait and balance issues.
Methods Used
- Visual inspection of signal quality after electrode attachment.
- Use of elastic bandages to minimize electrode movement.
- Calibration of dual top force plate for data collection.
- Implementation of TMS to assess motor evoked potentials.
Main Results
- Increased likelihood of eliciting motor evoked potentials.
- Successful assessment of corticospinal tract function in standing position.
- Method applicable to various neurological populations.
- Enhanced understanding of neurophysiology related to gait and balance.
Conclusions
- The protocol is effective for assessing lower extremity neurophysiology post-stroke.
- Standing position during TMS improves assessment outcomes.
- This method can be adapted for other neurological conditions.
