Nystagmus duration changes of learning disabled children during sensory integrative therapy.

Sensory integrative therapy was administered to 43 learning disabled children categorized according to their pretherapeutic duration of postrotary nystagmus. The duration then was recorded after relatively short or long treatments. Children displaying initial subnormal nystagmic functioning responded to therapy with increases in duration while others displayed decreases, and these effects were more apparent after long therapy. These data support the claims that learning disabled children can be meaningfully categorized according to their nystagmic responses and that attention to their interoceptive sensory functioning may be of clinical significance.
