Effect of foot sole patch for daily activity

This experiment tested the effectiveness of pain relief patches using a human factors engineering method from public health. It is said that sticking pain relief patches on the plantar arch of the foot can help reduce fatigue around the hips and knees. Measurements for this study involved the evaluation of the static upright postures of 8 female participants. I got the subject to measure blood pressure and cardiac beats rate. Moreover, the Visual Analog scale questionnaire survey was conducted. Data were collected a total of four times per person, both before and after exercising with and without the pain relief patches. The eye-opened state and the eyelid closure state were added, respectively．Since it measured by eight patterns, 64 data was collected. While there were no effects observed before exercising for both conditions, There were no significant difference in area between Center of pressure (COP) measurements during the static upright postures in an eyes-open state after conducting the exercises with and without the pain relief patches. Consequently all participants reported that they did not feel the pain relief patches on their feet. The results of this experiment support the fatigue-alleviating effects of the pain relief patches and suggest its possibility in maintaining a more stable static upright posture. It was considered that post physical activity, due to decreasing the trajectory of COP, it was effect of possibility anti-fatigue function.
