PURPOSE: The purpose of this experiment is to determine the effects that the quadriciser has on range of motion and upper body motor control in children with mixed quadriplegia due to chromosomal deletion disorders. METHODS: Two subjects with different chromosomal deletion disorders participated in this study. They completed a 10-week passive exercise intervention using the quadriciser. Range of motion of the elbow and shoulder were taken pre and post quadriciser use for both subjects. For one subject, hip and knee measurements were also taken. Both subjects also completed a timed reach task pre and post quadriciser use to test motor control. RESULTS: The only consistent changes in range of motion between pre and post quadriciser use were in one subject’s right shoulder and the other subject’s left knee. All other changes in range of motion showed some improvement, but were inconsistent. Reach task time generally increased post quadriciser use for one subject showing a decrease in task speed. The other subject did not experience any changes in reach task time. CONCLUSIONS: The quadriciser may temporarily improve range of motion in people with mixed quadriplegia. However, there is no evidence to support that it helps to improve upper body motor control.
