The physiological mechanisms underlying forehead muscle biofeedback for stress reduction are not well understood. A common hypothesis considers the frontales to be "key muscles" uniquely indexing the degree of tension present in the general musculature. We tested this hypothesis under conditions ranging from relaxation to maximum physical effort. The hypothesis was not supported. Changes in forehead muscle activity were limited primarily to reflecting changes in head and neck muscle tension.
前额肌肉生物反馈减轻压力的生理机制尚未得到充分理解。一个常见的假设认为额肌是“关键肌肉”，独特地指示全身肌肉组织中存在的紧张程度。我们在从放松到最大体力消耗的条件下测试了这一假设。该假设未得到支持。前额肌肉活动的变化主要局限于反映头部和颈部肌肉紧张度的变化。
