Abstract
- Proprioceptive sensation in rotation of the trunk about a vertical axis was investigated in normal human subjects. Subjects pointed at the big toe with the nose to test the accuracy of positioning of the trunk. Active rotation of the head and shoulders on the stationary hips and legs to align the nose and toe, was not significantly more accurate than moving the hips, legs and toe under the fixed head and shoulders. Passive displacements were imposed on the head and shoulders, or on the hips and legs. Thresholds for the detection of these displacements were unchanged by the exclusion of vestibular stimulation. Thresholds were highest (still less than 1 degree) at the slowest angular velocity (0.1 degree/s) and became lower as the angular velocity was increased.
