BACKGROUND AND PURPOSE:/st>Persistent deficits in gait speed and spatiotemporal symmetry are prevalent following stroke, and can limit the achievement of community mobility goals. Rehabilitation can improve gait speed, but has shown limited ability to improve spatiotemporal symmetry. The incorporation of combined visual and proprioceptive feedback regarding spatiotemporal symmetry has the potential to be effective at improving gait. CASE DESCRIPTION: /st>A 60 year old male (18 months post-stroke) and a 53 year old female (21 months post-stroke) each participated in gait training to improve gait speed and spatiotemporal symmetry. Each participant performed 18 sessions (6 weeks) of combined treadmill-based gait training followed by overground practice. To assist with re-learning spatiotemporal symmetry, treadmill-based training for both participants was augmented with continuous real-time visual and proprioceptive feedback from an immersive virtual environment and a dual belt treadmill, respectively. OUTCOMES: /st>Both participants improved gait speed (Participant 1: 0.35 m/s improvement; Participant 2: 0.26 m/s improvement) and spatiotemporal symmetry. Participant 1, who trained with step length symmetry feedback, improved his step length symmetry ratio, but not his stance time symmetry ratio. Participant 2, who trained with stance time symmetry feedback, improved her stance time symmetry ratio. She had no step length asymmetry prior to training. DISCUSSION:/st>Both participants made improvements in gait speed and spatiotemporal symmetry that exceeded those reported in the literature. Further work is need to ascertain the role of combined visual and proprioceptive feedback for improving gait speed and spatiotemporal symmetry following chronic stroke. |
