The Influence of Pain Distribution on Walking Velocity and Horizontal Ground Reaction Forces in Patients with Low Back Pain

Table 3

Mean and standard deviation of absolute and relative gait velocity for the control, back pain only (BPO) and back pain with unilateral referred leg pain (L GP) groups.

Walking speed conditions	Relative gait velocity	Control	BPO	LGP
		Mean ± SD	Mean ± SD	Mean ± SD
Preferred	Normalized (% body height per second)	0.9 ± 0.1	0.8 ± 0.9*	0.8 ± 0.1†
	Absolute (m/s)	1.6 ± 0.5	1.3 ± 0.5	1.3 ± 0.5
Fastest	Normalized (% body height per second)	1.3 ± 0.1	1.2 ± 0.2	1.0 ± 0.2†
	Absolute (m/s)	2.1 ± 0.8	2.1 ± 0.8	1.7 ± 0.8

*The BPO group walked significantly slower than the control group during the preferred walking speed condition (𝑃<.0005).
†The LGP group walked significantly slower than the control group in both the preferred and fastest walking speed conditions (𝑃=.002).
