TABLE 3.

Limits of stability test scores recorded after the no-nap condition (NN) and the 60-min (N60) nap opportunity.

Limits of stability	Average (8 directions)
	NN	N60	P value	Cohen’s d	Δ%
RT (s)	0.55 ± 0.19	0.52 ± 0.20	0.54	0.15	-6.6
MVL (grad/s)	5.9 ± 1.7	6.5 ± 2.8	0.18	0.25	-8.0
EPE (%)	78.3 ± 8.0	83.3 ± 7.7	0.06	0.63	5.8
MXE (%)	93.5 ± 3.5	95.8 ± 2.8	0.16	0.72	2.4
DCL (%)	77.3 ± 5.8	78.0 ± 9.2	0.78	0.09	0.0

RT: Reaction time; MVL: Movement velocity; EPE: Endpoint excursions; MXE: Maximum excursions; DCL: Directional control.
