Physiological responses during active video games in spinal cord injury: a preliminary study.

Objectives: Investigate the physiological responses to active video games (AVG) in individuals with spinal cord injury by comparing oxygen consumption (VO) and heart rate (HR) during an AVG session and at the ventilatory thresholds (i.e., anaerobic threshold and respiratory compensation point); and by calculating the session energy expenditure (EE).

Aerobic Stimulus Induced by Virtual Reality Games in Stroke Survivors.

Objective: To evaluate whether virtual reality games (VRGs) in stroke survivors produce significant and reproducible heart rate and oxygen consumption (V˙o) responses during their execution, corresponding to an intensity between the anaerobic threshold (AT) and the respiratory compensation point (RCP).

Design: Single-subject, repeated-measure design.

Setting: Stroke survivors registered from a rehabilitation program.
