Semiconductor membrane which was contained textile goods was studied for efficacy of pain control clinically and basically. Twenty chronic low back pain patients were enrolled the study to evaluate the degree of relief of pain in pain clinic. Characteristic of materials of semiconductor membrane was studied by X-ray analysis method, electron spin spectrum method and electron spectrum oxidized-deoxidized potential measuring method. Clinical result was effective for twenty chronic low back pain patients. Basic result was that we recognized a contact electric potential difference and signal reverted to superoxide by respective method. We concluded that effect of relief of pain due to semiconductor membrane might be resulted in improved blood flow by suitable stimulation to living person.
