Abstract
Background: Poststroke hemiparesis presents with motor asymmetry and decreased postural control leading to functional limitations. Serious games (SG) for balance rehabilitation of people with stroke may improve motor recovery, and the visual and auditory feedback provided by the SGs helps to explain the therapeutic benefits. However, the contribution of SG combined with kinesthetic and verbal cues during balance training has not been investigated. The aim of this study is to compare the effects of two feedback conditions for an SG balance intervention, with or without the addition of kinesthetic and verbal cues, on balance performance of people with stroke. Methods: Thirty people with chronic poststroke hemiparesis and balance impairment participated in this randomized controlled trial and performed 14 individual SG training sessions combined with kinesthetic and verbal cues provided by the physical therapist or with SG's feedback only. Outcomes were assessed before training (pre), 1 week after the end of training (post), and 8 weeks after the end of training, which were adopted as the follow-up period, using the Balance Evaluation Systems Test, Lower Limb Subscale of Fugl-Meyer, six-minute walk test, and Stroke-Specific Quality of Life Scale. Results: The results showed that SG combined with kinesthetic and verbal cues improved outcomes relating to lower limb function and some balance domains (biomechanical constraints and limits of stability outcomes) better than with SG's feedback only. Both groups had similar significant improvement in quality of life and long-distance walking performance. Conclusion: This study is the first to directly compare two feedback conditions for SG-based balance intervention. The addition of kinesthetic and verbal cues during the SG balance improved aspects of postural control better than without this form of feedback.
