ObjectiveThe purpose of this study was to assess the preliminary efficacy and feasibility of smartphone-based visual feedback trunk control training (SPVFTCT) for improving balance and trunk performance in stroke patients.DesignTwenty-four patients who had experienced a stroke more than 6 months previously and could sit and walk independently participated in the study. The participants were allocated to a SPVFTCT (n = 12) or to a control group (n = 12). Both groups completed five 80-minute sessions per week of conventional rehabilitation for 4 weeks. The SPVFTCT group additionally received three 20-minute sessions per week of SPVFTCT for 4 weeks. The outcome was assessed using static balance assessment, the modified functional reach test, the timed up and go test, and the trunk impairment scale. Feasibility of SPVFTCT was evaluated by retention, adherence, acceptability, and safety.ResultsThe static balance assessment, modified functional reach test, timed up and go test, and trunk impairment scale scores in the SPVFTCT group improved significantly compared to those in the control group (P < 0.05). In the SPVFTCT group, retention and adherence rates were 100% and 97%, respectively. All participants reported that SPVFTCT was enjoyable, easy to use, and helpful for their recovery.ConclusionsThe SPVFTCT approach is a feasible method to improve balance and trunk performance in stroke patients.To Claim Cme CreditsComplete the self-assessment activity and evaluation online at http://www.physiatry.org/JournalCME CME OBJECTIVES:: Upon completion of this article, the reader should be able to: (1) Understand the role of trunk control in postural stability and functional improvement; (2) Describe the benefits of smartphone-based visual feedback trunk control training (SPVFTCT); and (3)Discuss the feasibility of incorporating smartphone-based visual feedback trunk control training in stroke rehabilitation.LevelAdvancedAccreditation: The Association of Academic Physiatrists is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians.
