Correlations between age of particular participants and VAG parameters.

	VMS*	P1*	P2*	H *
Left knee	0.53	0.58	0.60	−0.18
Right knee	0.52	0.54	0.64	−0.28

  ^*Results are expressed as correlation coefficients; all factors were statistically significant (P < 0.05).

VMS, variance of the mean squares; P1 and P2, power spectral density bands: 50–250 Hz and 250–450 Hz, respectively; H, entropy.
