- Abstract
- The aim of this study was to identify both the mechanical and reflex properties associated with
spasticity in hemiplegic patients. Ten hemiplegic patients were included in this study. Multiple
pendulum tests were executed for each subject, and knee joint angle and EMG of Rectus
Femoris muscle were measured. The neuromusculoskeletal system model was developed from
generally accepted mechanism and identified through minimization of the error in the modelpredicted
pendulum trajectories. The identification was successful in terms of small error in
simulated kinematics and high sensitivity and precision of simulated torque against EMG activity.
The reflex threshold showed significant difference between different clinical scores (p<0.01) and
significant negative correlation (r=-0.93) with the EMG duration. It is expected that the suggested
method may help in understanding mechanisms underlying spasticity.
