Abstract:
Objective To study the gait characteristics of low back pain(LBP)pilots by three-dimensional gait analysis technique,and provide basic data for the development of targeted rehabilitation programs for LBP pilots.Methods From March 2017 to May 2018,35 LBP pilots were enrolled.The pilots wore sensors accurately and walked straightly for 15 steps.The OptiTrack three-dimensional gait analysis system was used to monitor space distance parameters and joint range of motion.Results The step width[(0.18±0.09)m],step speed[(0.95±0.21)m/s],left foot deflection angle(-4.31±9.64)°,left step length[(0.54±0.14)m],left single support phase time[(452.43±55.98)ms)],and standing phase time[(628.41±122.4)ms]in the LBP pilots were lower than those in the normal population.The right double support phase time was slightly shorter than the left side in the LBP pilots.In-toeing gait presented commonly in the LBP pilots.The right single support phase time[(455.84±51.06)ms]and the standing phase time[(674.59±202.32)ms]were prolonged.The step length on the right was compensatively increased and significantly higher than that on the left(P=0.012).The flexion(6.88±4.47)° and extension(-15.78±5.80)° of the right hip joint and the flexion of the right knee joint(32.03±5.26)° were weaker than those of normal population.Right knee hyperextension was common in LBP pilots.Conclusion In-toeing gait presents commonly in LBP pilots.Their step width,step speed,foot deflection angle,and step length are narrower than those of the normal population.The lower limbs are mainly characterized by reduced flexion of the hip and knee joints and hyperextension of the right knee.It is essential to take more targeted functional exercise to prevent and treat LBP in pilots.
