Summary

This study is a cross-sectional study that aims to explore the correlation between clinical assessment and neurophysiological assessment in SCI. The clinical outcome assessment are modified-Modified Ashworth scale (m-MAS) and lower extremity motor score. The neurophysiological outcome is H-reflex outcome.

Detailed description

Spinal cord injury (SCI) cause disruption of descending control pathway in spinal cord. The disruption of descending control induce impaired motor and sensory function below the level of injury, as well as the electrical signal from supraspinal pathway. During spinal shock phase, spinal motoneuron become hypoexcitability, as resulting in muscle hypotonicity or flaccidity in clinical manifestation. The spinal motoneuron gradually increase during sub-acute to chronic phase as resulting in development of spasticity in SCI. Development of spasticity is realted to increase of spinal motoneuron excitability, which shown in a decrease in H-reflex latency and increase in Hmax/Mmax ratio. A previous study shown a medium correlation between Hmax/Mmax ratio and MAS in SCI and stroke people. Moreover, the MAS shown a strong correlation with Fugle-meyer score in stroke people. However, it remains unclear in correlation between clinical outcome and neurophysiological outcome assessment of spasticity, and the correlation of spasticity and the motor function in SCI. This study aims to explore the correlation between clinical assessment and neurophysiological assessment of spasticity in SCI.The clinical outcome assessment are modified-Modified Ashworth scale (m-MAS) and lower extremity motor score (LEMS). The lower extremity motor score is obtained from American Spinal Injury Association (ASIA) imapirement scale. The neurophysiological outcome assessment is H-reflex methode. All particiants who will participated into this study will be assessed the m-MAS, LEMS and H-reflex.
