TABLE II.

Coefficient of variation (CV) values (mean and standard deviation) for amplitude, peak velocity, small and large turn amplitude, turn count, and step count across three body segments (Head, Thoracic, and Lumbar). These CV values were calculated from each individual’s weekly CV and then averaged across all subjects.

	Head	Thoracic	Lumbar
	CV (SD)
Amplitude (°)	0.83 (0.04)	0.84 (0.04)	0.83 (0.05)
Peak Velocity (°/sec)	0.68 (0.07)	0.57 (0.08)	0.54 (0.06)
Small Turn Amplitude (°)	0.30 (0.02)	0.32 (0.06)	0.32 (0.06)
Large Turn Amplitude (°)	0.55 (0.02)	0.55 (0.03)	0.56 (0.03)
Small Turn Peak Velocity (°/sec)	0.47 (0.03)	0.41 (0.06)	0.42 (0.06)
Large Turn Peak Velocity (°/sec)	0.54 (0.06)	0.47 (0.08)	0.47 (0.09)
Turns (n)	0.46 (0.15)	0.47 (0.18)	0.45 (0.17)
Step Count (n)	0.51 (0.16)	0.53 (0.18)	0.54 (0.28)
