Biofeedback improves postural control recovery from multi-axis discrete perturbations

Table 2 Incidence of response types by display type

	Display OFF	Display ON	Erroneous display
Typical response	182	396	17
Delayed response	43	45	11
Uncontrolled response	6	7	8
Chi-squared value compared to OFF (df = 2)		11.14 (p < .005)	29.24 (p < .0001)

The number of perturbations which resulted in each type of response (typical, delayed, or uncontrolled) is shown for each type of vibrotactile display type (OFF, ON, Erroneous). Chi-squared tests demonstrate significant differences between ON vs. OFF, and between Erroneous vs. OFF.
