  1. Analgesic effects induced by TENS and electroacupuncture with different types of stimulating electrodes on deep tissues in human subjects 老師:蔡育秀 報告者:梁家瑜

  2. 摘要 • TENS :1. Cone-shaped metal 2. Rubber 3. Large soft surface electrodes • EA : 1. insulated 2.non-insulated

  3. Introduction Pain thresholds in deep tissues : • used hypertonic saline injection as pain stimulus. • muscle pain measurement is pressure algometry

  4. Methods(1) • Subjects :16 healthy male subjects , aged 24 • Stimulating electrodes : TENS :1. Cone-shaped metal 2. Rubber 3. Large soft surface electrodes EA : 1. insulated 2.non-insulated • TENS and EA : TENS :Two pairs (4 electrodes) the skin of the right anterior femoral region EA : depth of about 30 mm as Teh-chi

  5. Methods(2) • Deep pain measurement : • Skin :The needle was inserted about 3 mm • Fascia : Muscle twitching was rarely evoked until the stimulus current reached pain threshold. • Muscle : After penetration of the hard membrane, the physical resistance to needle penetration suddenly disappeared. Muscle twitching was observed frequently at low stimulus intensity. • Periosteum : The needle penetrated until it touched hard bone. Muscular twitching was rarely observed during electrical stimulation.

  6. Results • Pain thresholds in deep tissues : • periosteum < fascia < skin< muscle

  7. Discussion • 本研究目的是找到合適的電極在深組織鎮痛作用，尤其是在肌肉和骨膜 • 高強度和高頻率EA(非絕緣針電極) 比TENS(不同類型電極)產生更加有力的鎮痛作用於皮膚和筋膜。
