The relationship between cervical flexor endurance, cervical extensor endurance, VAS, and disability in subjects with neck pain

Table 2 Between groups differences for pain intensity, neck disability and muscle endurance tests

Characteristic	Acute/subacute pain (n = 13)	Chronic pain (n = 17)	p
VAS, X(SD)*	41.23 (24.48)	33.18 (23.23)	0.36
NPDS-I, X(SD)*	34.46 (17.64)	49.44 (15.01)	0.01
NFME test, mo (range)^a**	44 (27–60)	30 (23.5-61.5)	0.50
NEE test, X(SD)*	261.92 (137.46)	235.12 (162.13)	0.63

Differences between groups were analyzed with a Student unpaired t test* or a Mann–Whitney U test** as appropriate.
^aMeasures with a non-Gaussian distribution are expressed as median and interquartile range (25th-75th).
