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.
四名受试者在进行负功后出现疲劳，两名受试者在颌肌进行负/正功后出现疲劳。另外四名受试者在肌肉运动后未出现疲劳。在出现疲劳的受试者中，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%。有人认为，这种扭曲的动觉是由疲劳引起的颌肌纤维收缩失败或持续收缩导致的，进而导致来自肌梭和/或腱器官的传入冲动流发生扭曲。
