Exploration of computer games in rehabilitation for brain damage

Cognitive and physical deficits are consequences of stroke/traumatic brain injuries (TBI). Without rehabilitation activity problems persist i.e. limitations to handle personal care, the work situation, and recreational activities. The aim of this study is to test an application of Virtual Reality (VR) technology with 3D computer games as an occupational therapy assessment/treatment method in rehabilitation for patients with cognitive and physical deficits. We also wanted to investigate if playing computer games resulted in improved cognitive function. An easy-to-use semi-immersive workbench with haptic game selection menu was located at an activity centre. The training activities were 3D computer games. Every time an activity was run, data about the hand movements were collected and analyzed. Quantitative variables were time (s) to perform the test, average velocity (m/s) and, tremor or uncertainty in movements HPR). Executive functioning was examined by utilizing Trial Making Test. The intervention involved five patients. Results provide evidence to support the use of 3D computer games in cognitive rehabilitation. As an implementation tool within the occupational therapy area, this technology seems to be well adapted to the technological and economical development of society in Sweden.
