BackgroundComplex regional pain syndrome (CRPS) is a disease of the limbs composed of various disorders and defined by the cardinal symptom of pain. So-called exergames with a combination of physical activity and fun are increasingly being offered as part of treatment. Exergame therapy could also provide CRPS patients with repetitive training, reward and motivation.MethodIn this study 10 adult patients with CRPS of the hand (50% acute) received a 30 min therapy session using MindMotion™GO. MindMotion™GO is a software that enables control of the integrated games through visual feedback. Outcomes were the subjectively perceived workload (National Aeronautics and Space Administration-task load index, NASA-TLX), user-friendliness (system usability scale, SUS) and pain (numeric rating scale, NRS).ResultsThe CRPS patients rated the average workload as appropriate with a total score of 50.9 points (SD ± 18.13). The user-friendliness of the system was judged to be acceptable with an average total score of 89.5 ± 7.53 points. There were no significant changes in pain intensity after the exergames. The subgroup analysis (acute versus chronic) showed differences in the assessment of the individual dimensions of the workload.ConclusionIn this study the use of exergames proved to be a suitable tool for rehabilitation of the hand in adult CRPS patients. Whether exergames represent an effective rehabilitation strategy should be examined by means of functional and activity-related target criteria in a representative sample in a randomized controlled study.
