In this study, we reported the physical therapy in a subject who had difficulty with walking after viral encephalitis. In this case, we found that muscle tone in the right lower back was increased compensating for lowered muscle tone of the left obliquus internus abdominis and right gluteus medius. In gait, the subject showed a tendency to fall forward to the left in the early left stance phase and to fall backwards to the right in the early right stance phase resulting in an unsafe, unstable and unsustainable gait. In physical therapy, treatment for the lowered muscle tone was verified using electromyography, and the tendency to fall in gait was improved. The results suggest that normal muscle tone in the back, obliquus internus abdominis and gluteus medius is related to the stability of the pelvic girdle and hip joint.
