BACKGROUND: Physical inactivity and low resting heart rate variability (HRV) are associated with an increased cardiovascular deconditioning, risk of secondary stroke and mortality. Aerobic dance is a multidimensional physical activity and recent research supports its application as a valid alternative cardiovascular training. Furthermore, technological advances have facilitated the emergence of new approaches for exercise training holding promise, especially those methods that integrate rehabilitation with virtual gaming. OBJECTIVE: The purpose of this study was to evaluate cardiac autonomic modulation in individuals with chronic stroke post-training using a virtual reality - based aerobic dance training paradigm. METHODS: Eleven community-dwelling individuals with hemiparetic stroke [61.7( ± 4.3) years] received a virtual reality-based dance paradigm for 6 weeks using the commercially available Kinect dance video game "Just Dance 3." The training was delivered in a high-intensity tapering method with the first two weeks consisting of 5 sessions/week, next two weeks of 3 sessions/week and last two weeks of 2 sessions/week, with a total of 20 sessions. Data obtained for HRV analysis pre- and post-intervention consists of HRV for ten minutes in (1) supine resting position; (2) quiet standing. High-frequency (HF) power measures as indicators of cardiac parasympathetic activity, low-frequency (LF) power of parasympathetic-sympathetic balance and LF/HF of sympatho-vagal balance were calculated. YMCA submaximal cycle Ergometer test was used to acquire VO2 max pre- and post-intervention. Changes in physical activity during dance training were assessed using Omran HJ-321 Tri-Axis Pedometer. RESULTS: After training, participants demonstrated a significant improvement in autonomic modulation in the supine position, indicating an improvement in LF=48.4 ( ± 20.1) to 40.3 ( ± 8.0), p=0.03; HF=51.5 ( ± 19) to 59.7 ( ± 8), p= 0.02 and LF/HF=1.6 ( ± 1.9) to 0.8 ( ± 0.26), p=0.05]. Post-training the participants had significantly higher VO2max. Number of steps during dance intervention significantly increased from the 1st to the 20th session (p<0.05). CONCLUSION: The current study is the first to assess the effect of a virtual reality-based aerobic dance training paradigm on HRV among individuals with chronic stroke. Given that the paradigm used in this study improves cardiac autonomic control, future studies should incorporate dance as an adjuvant therapy into clinical treatment program and assess its long-term efficacy.
