| Abstract |
Objective
To study gait patterns of patients with chronic lumbosacral radiculopathy, and to investigate whether gait parameters can reflect functional deficit in relation to the level of lumbosacral radiculopathy.
Method
Conventional physical examinations and three- dimensional gait analysis were performed on 24 patients with chronic lumbosacral radiculopathy (twelves with L5 and twelves with S1 radiculopathy) who were diagnosed by electrophysiologic study and magnetic resonance imaging study, and 12 healthy control subjects. Temporospatial, kinematic and kinetic parameters of patients were compared with those of the control group.
Results
In patients with lumbosacral radiculopathy, walking velocity, stride length, ratio of single support time todouble support time and range of pelvic obliquity were less than control group. Increased double support time, decreased maximal hip extension angle, decreased ankle plantar flexion angle during preswing phase and decreased maximal ankle plantar flexion moment were noted in S1 radiculopathy patients compared with control group. Decreased pelvic rotational range and decreased ankle dorsiflexion moment were specific in L5 radiculopathy patients compared with control group.
Conclusion
Using three-dimensional gait analysis, we could identify specific gait parameters to reflect functional deficit related to the level of lumbosacral radiculopathy. (J Korean Acad Rehab Med 2004; 28: 586-591) |
