Further Evidence on the Dynamics of Self-Injurious Behaviors: Impact Forces and Limb Motions

The dynamics of self-injurious behaviors were examined in 8 adults with mental retardation. Analysis of trajectories of the arm movements and impact forces of head blows found a high degree of cycle-to-cycle consistency in the qualitative dynamics of limb motions, indicating the motions are often st...

Summary:The dynamics of self-injurious behaviors were examined in 8 adults with mental retardation. Analysis of trajectories of the arm movements and impact forces of head blows found a high degree of cycle-to-cycle consistency in the qualitative dynamics of limb motions, indicating the motions are often stereotyped in nature.
