The effect of acupuncture on alpha-motoneuron excitability
The analgesic effect of acupuncture is well known. Areas in the brain and higher centres that are activated by acupuncture have been mapped out. Some of these areas are also implicated in the modulation of motor function. In addition to pain relief, acupuncture has been found to increase range of movement in patients with increased muscle tone. There is, however, scant knowledge of the mechanisms underlying this therapeutic effect.
