Abstract
[Purpose] This study aimed to evaluate the improvement in lower extremity hemiplegia
following brain tumor operation with an integrated volitional control electrical
stimulator (IVES). [Participant and Methods] A 40 year-old male with anaplasic
oligodendroglioma in the right frontal lobe underwent IVES in the rectus femoris and
tibialis anterior muscles using the power-assist and sensor-trigger modes. Lower extremity
motor function was assessed before and after the therapy sessions. An assessment was
conducted using various techniques, including static posturography and surface
electromyography. [Results] Static posturography showed an improvement in the center of
pressure and sway area after IVES gait training. Based on a time-series statistical
parametric mapping analysis, the activation pattern of each muscle after the treatment was
different. Muscle synergy analysis revealed decreased total variance accounted for by a
single synergy in the affected and normal sides after the treatment. [Conclusion] Patients
with chronic hemiplegic lower extremity impairment responded well to IVES gait training.
Electromyography-triggered functional electrical stimulation may enhance sensory-motor
integration. Proprioceptive feedback plays a crucial role in improving motor control.
