Sensory-Motor Incongruence Causes Pain

Just back from a terrific convention at AOTA and swing by Washington D.C. Lots to blog on, but also need to unpack.

Here's some links to interesting work from a group working with sensory-motor incongruence:

"In 66% of health volunteers, abnormal sensations of pain (“numbness, pins and needles, moderate aching and/or a definite pain”) or other sensations (“perceived changes in temperature, limb weight, altered body image, disorientation”) were reported following artificially-induced sensory-motor incongruence."

This might explain some of the unusual sensitivities and reports of pain from children with mild birth injury (and sensory-motor reorganization), extreme prematurity, and other pain syndromes like reflex sympathetic dystrophy. When our body senses and sight are mismatched, the disconnect causes some of us to feel real pain.

Interestingly, the group has been using mirror / visual feedback imagery and found that it reduces pain perception in some patients with CRPS or complex regional pain syndrome.

    Liz here from I Speak of Dreams. The second link to the powerpoint is broken, goes to 404 page.

  2. Thanks, Liz. I hope I just corrected it.
