Effect of practice with motion interactive video games on goal-directed arm movements in children with cerebral palsy: a kinematic evaluation
(English)Manuscript (preprint) (Other academic)
Objective: The aim of the present study was to evaluate the quality of goal-directed arm movements in children with cerebral palsy after four weeks of daily practice with motion interactive games, and to explore and compare the applicability of various kinematic parameters in a virtual context compared to a situation with real objects.
Methods: Fifteen children with CP, 6-16 years, practiced with the EyeToyâ for PlayStation2â in their homes during four weeks. Before and after the intervention kinematics and kinetics were captured with a five camera motion analysis system (Proreflex, Qualisys AB, Gothenburg, Sweden) and a force plate. The children performed arm movements towards both virtual and real targets.
Results: The children used a more economic reaching strategy with shorter Centre of pressure paths, improved Movement precision, and reduced variability in Maximal shoulder angles during play after practice. Transfer of improved motor control to goal-directed arm movements towards real targets was also indicated by increased Movement smoothness, and while reaching with the non-dominant side, reduced Centre of pressure paths path. The spatiotemporal characteristics proved complex to interpret in terms of improved motor control.
Conclusions: When taking the constraints of the tasks into account the relevant kinematic parameters explored support the conclusion that practice with motion interactive games resulted in an improved motor control. The results of this study illuminate the importance of considering both the nature of the task and the context in which movements are performed when selecting and interpreting kinematic parameters.
