Analysis of Asymmetry of the Forces Applied on the Lower Limb in Subjects with Nonspecific Chronic Low Back Pain

Table 4

The peaks of the forces applied on the leg (dominant side) in normal and NCLBP subjects.

Parameter	Fz1 (N/BW)	Fz2 (N/BW)	Fz3 (N/BW)	Fy (N/BW)	Fx1 (N/BW)	Fx2 (N/BW)
NCLBP	1.038±0.099	0.86±0.0398	1.106±0.0356	0.089±0.022	0.178±0.03	0.055±0.011
Normal	1.02±0.0354	0.0857±0.0389	1.13±0.045	0.1004±0.036	0.19±0.0218	0.053±0.016
𝑃 value	0.25	0.42	0.038	0.214	0.138	0.353

Values are mean ± SD. N: newton, BW: body weight, Fz: vertical force, Fy: mediolateral force, and Fx: anteroposterior force.
