疲劳是由四个人类受试者在负性工作后产生的，两个受试者在下颌肌肉的负性/正性工作后产生的。另外4名受试者在肌肉锻炼后没有出现疲劳。在疲劳的受试者中，感知和/或重复产生预定下颌姿势的能力，即下颌动觉，受损约285%。有人建议，扭曲的动觉导致疲劳引起的失败，或疲劳引起的持久性，颌肌纤维收缩，这反过来又导致扭曲的传入冲动从肌梭和/或肌腱器官的流动。
Fatigue was developed by four human subjects after negative work, and by two subjects after negative/positive work by the jaw muscles. Another four subjects did not develop fatigue subsequent to muscular exercise. In subjects with fatigue, the ability to perceive and/or produce repetitively a predetermined mandibular posture, i.e. mandibular kinesthesia, was impaired by about 285%. It is suggested that the distorted kinesthesia resulted from either a fatigue-induced failure of, or a fatigue-induced persistence of, jaw muscle fibers to contract, which in turn led to distorting flows of afferent impulses from muscles spindles and/or tendon organs.
