We lowered and raised the leg of a supine subject periodically, with the leg stationary between movements (square wave). The Traube-Hering-Mayer wave (THM congruent to 0.1 Hz) was captured by or locked on to the leg movement over a certain frequency range, this is usually called the entrainment range. Square wave periodic leg movement in this manner on 10 male subjects, mean age 22 years, demonstrated that the THM frequency can be entrained. The lower limit of the entrainment bandwidth is 0.0841 (SD 0.0030) Hz and the upper limit is 0.1176 (SD 0.0013) Hz. Further examination showed that this phenomenon is independent of the breathing input. Comparison with the Traube-Hering-Mayer entrainment techniques of breathing and periodic neck suction using the Eckberg collar which stimulates the baroreceptors showed similar results. This work supports the hypothesis that the local reflex response and the baroreceptor outflow entrain the THM frequency.
