RESUMEN
Objective:To quantify the kinematic changes in the gait cycle among youths with chronic, nonspecific low back pain (CNLBP).Methods:A Qualisys 3D optical motion capture system was used to document the gait kinematics of 11 youths with CNLBP and 11 healthy counterparts. Gait profile scores and movement analysis profiles were then calculated.Results:The young CNLBP subjects exhibited gait abnormalities, as reflected by the significant difference of the gait variable the range of motion of the dominant knee between the CNLBP and healthy groups [(5.66±1.83)° vs (3.64±1.13)°]. Gait profile scores and movement analysis profiles are applicable to evaluating them.Conclusions:There manifested gait abnormalities in youth CNLBP patients. Gait profile scores and movement analysis profiles are applicable to evaluating them.
