Brief Summary

As human beings live longer, geriatric disease develop, one of which was stroke whose prevalence elevated by aging. Increased spasticity is a common symptom after stroke and may hinder patient from rehabilitation. The spasticity was evaluated by subjective judgement before. However, in the recent studies, the electrophysiological test, an objective evaluation, showed possibly positive correlation with the spasticity. They compared stroke patients' hemiplegic side with non-hemiplegic side by H/M ratio which showed significant difference. The stroke patients included in studies had stroke onset over 2 years. Therefore, investigators wonder if H/M ratio can evaluate spasticity in stroke patients onset within 2 years and if H/M ratio is correlated to spasticity.

Outcome Measures

Primary Outcomes (3)

  • Nerve conduction study (H/M slope)

    To compare the hemiplegic side and sound side difference, investigators will exam four limbs twice and obtain two data of H and M. Electrodes were placed on each limb and the electrical impulse from low to high ampere will elicit several data of H and M from low to high values. Average of H slope will be calculated and divided by average of M slope, without unit.

    30 minutes

  • Nerve conduction study (H/M maximal amplitude)

    To compare the hemiplegic side and sound side difference, investigators will exam four limbs twice and obtain two data of H and M. Electrodes were placed on each limb and the electrical impulse from low to high ampere will elicit several data of H and M from low to high values. Maximal H value will be divided by maximal M value, without unit.

    30 minutes

  • Nerve conduction study (H/M threshold)

    To compare the hemiplegic side and sound side difference, investigators will exam four limbs twice and obtain two data of H and M. Electrodes were placed on each limb and the electrical impulse from low to high ampere will elicit several data of H and M from low to high values. The ampere which elicited first data of H or M will be the threshold. The threshold of H will be divided by the threshold of M, without unit.
