The purpose was to examine the differences in kinesthetic ability, at the elbow joint, between children with (n = 15) and without (n = 15) spastic hemiplegia. The Kin Com 125 AP isokinetic dynamometer Configuration Chattanooga was used. Results revealed significant (p less than 0.05) interaction between participant groups and side which was a repeated measures factor (nonaffected side for CP group and dominant side for nonCP group vs. affected side for CP and nondominant side for nonCP group) with respect to the passive reproduction of movement (PRM) and detection of passive movement (DPM). The interaction was attributed to the kinesthetic deficits of the hemiplegic participants compared to the control group. A significant relationship was found between the level of spasticity and PRM scores. (Contains 5 tables and 2 figures.)
