Unilateral axial muscle vibration, eliciting a proprioceptive volley, is known to incite steering behavior.
Whole-body rotation while stepping in place also occurs as an after-effect of stepping on a circular treadmill (podokinetic after-rotation, PKAR).
Here, we tested the hypothesis that PKAR is modulated by axial muscle vibration.
If both phenomena operate through a common pathway, enhancement or cancellation of body rotation would occur depending on the stimulated side when vibration is administered concurrently with PKAR.
Seventeen subjects participated in the study.
In one session, subjects stepped in place eyes open on the center of a platform that rotated counterclockwise 60°/s for 10 min.
When the platform stopped, subjects continued stepping in place blindfolded.
In other session, a vibratory stimulus (100 Hz, 2 min) was administered to right or left paravertebral muscles at lumbar level at two intervals during the PKAR.
We computed angular body velocity and foot step angles from markers fixed to shoulders and feet.
During PKAR, all subjects rotated clockwise.
Decreased angular velocity was induced by right vibration.
Conversely, when vibration was administered to the left, clockwise rotation velocity increased.
The combined effect on body rotation depended on the time at which vibration was administered during PKAR.
Under all conditions, foot step angle was coherent with shoulder angular velocity.
PKAR results from continuous asymmetric input from the muscles producing leg rotation, while axial muscle vibration elicits a proprioceptive asymmetric input.
Both conditioning procedures appear to produce their effects through a common mechanism.
We suggest that both stimulations would affect our straight ahead by combining their effects in an algebraic mode.
