To investigate the effect of sensory imagery on subsequent movement, a unil
ateral Feldenkrais lesson of imaging a soft bristle brush passing over one-
half of the body and in which no movement occurred, was given to 12 naive s
ubjects. Forward flexion for each side of the body was measured at a sit-an
d-reach box. For 8 and 10 subjects who reported the perception of a side as
being longer and lighter following the sensory imagery, there was also a s
ignificant increase in the forward flexion range on that side.
