| Summary: | 碩士 === 國立成功大學 === 醫學工程學系 === 84 === The existing clinical measures for spasticity, by determining
the resistance to external imposed passive movement of a joint,
are usually subjective and qualitative. The aim of this
research is to improve a spasticity measurement system,
developed in our pervious study, for the quantification of
stretch reflex of the impaired limbs. The spasticity
measurement system consists of real-time controlled servemotor,
torque sensor, and EMG surface recording electrodes. For the
execution of different experiments, a friendly graphic user
interface is implemented in this study for on-line change of
parameters and for monitoring the data quality. The
quantification parameter is defined as averaged speed dependent
reflex torque (ASRT) for quantifying the spasticity. Three
subjects suffering from cerebrovascular accident (CVA) were
recruited for time-course study. Generally, higher ASRT can be
observed in involved elbow joint than the unaffected side. From
the time-course studies, ASRT and velocity sensitivity
increased with time in involved elbow joints. It can be
concluded that our spasticity measurement system with ASRT
parameter is suitable for quantitatation of muscle hypernotia.
