Abstract

|
|
The purpose of this study was to examine the effect of optic pathway on human body during Proprioceptive Neuromuscular Facilitation(PNF) treatment. Specifically, it’s intened to find out through electromyography(EMG), what kind on change occurred in a patient’s muscle when the patient saw the motor direction or when the patient didn’t. A pilot experiment Was made over the sophomores of Mokpo Science College the following findings were given; As an EMG was taken over three of muscles that worked during Flexion-Adduction-Ext. Rot., one of the PNF pattern, a patient showed relatively stronger muscle power while watching the movement with his eyes open than the same patient did with his eyes closed, and the disparity between the two cases Was statistically significant(P<0.05). In the pattern of Extension-Abduction-Int.Rot., a patient also showed relatively stronger muscle power while watching the movement than the same patient did without watching it, and the disparity between the two cases also were significant(P<0.05). As seen above, the effect of motor treatment, among physiotherapy methods seemed to be greater if a patient watched the motor direction during treatment, because it gave a stimulus to proprioception.
