Virtual reality: a healthy perspective

Slowed movements are a common consequence or correlate of illness, injury and ageing. Slow movements, including slow walking, are inefficient and add to the physiological burden (Ada et al, 2003). Unfortunately slow movements can frequently persist and contribute to long-term disability. However, research has demonstrated that exercise, including treadmill training, can improve long-term outcomes (Ada et al, 2003; Luft et al, 2008), although motivation and adherence to exercise remains problematic.
