Subjects with hip osteoarthritis show distinctive patterns of trunk movements during gait-a body-fixed-sensor based analysis

Table 4 GEE analysis of walking speed, step length and cadence^a

Outcome	Group	Group effect (95% CI)	P value
Walking speed	HC	0^b
	NDL	-0.4 (-0.4, -0.3)	< .001
	DL	-0.4 (-0.5, -0.3)	< .001
Step length	HC	0
	NDL	0.4 (-2.5, 3.3)	.79
	DL	-1.0 (-5.0, 3.0)	.63
Cadence	HC	0
	NDL	-0.1 (-4.4, 4.4)	.99
	DL	1.5 (-4.9, 8.1)	.64

Reference group: healthy control group.
^a Adjusted for walking speed, age, body height and body weight (walking speed: adjusted for age, body height and body weight).
^b Set to zero because HC was used as reference group.
Abbreviations: GEE, generalized estimating equation; HC, healthy control group; NDL, patients without a Duchenne limp; DL, patients with a Duchenne limp.Walking speed is expressed in m/s, step length in cm and cadence in steps/min.
