The Study On Gait Characteristics In The Patient With Lumbar Disc Herniation

ObjectiveThe walking characteristics of patients with lumbar disc herniation were quantitatively analyzed by using the three-dimensional gait analysis(3DGA)system,which provided objective basis for clinical diagnosis and treatment,rehabilitation training plan formulation and rehabilitation effect evaluation of patients with lumbar disc herniation.MethodA total of 20 healthy volunteers and 20 patients with low back pain(LBP)were included,and 20 patients were evaluated with the Oswestry disability index(ODI),the Japanese Orthopaedic Association(JOA)and Visual Analogue Score(VAS).The kinematics data of all subjects were collected using the three-dimensional gait analysis system.Infra-red marking points were pasted on the low back pain related sites on the subject’s body surface,a total of 19 points were pasted,and the subject walked within the prescribed route on the flat ground.Subjects are required to walk over a distance of 5 meters at a comfortable speed,and the walking distance was 4 times.The spss22.0 software was used for statistical analysis of patient scale scores and kinematics data of all subjects.Result1.The comparison between the affected limb and the uninjured limb of the lumbar intervertebral disc herniation group showed that the stride length of the affected limb was significantly reduced and the step frequency was significantly increased,and the difference in step length and step frequency was statistically significant(P<0.05),while the difference in stride length,knee flexion and extension range and hip flexion and extension range was not statistically significant(P>0.05).2.The comparison between the affected limb of patients with lumbar disc herniation and the limb of healthy volunteers on the same side showed that the stride length,stride length,flexion and extension range of knee joint,and flexion and extension range of hip joint were significantly reduced.The results of step length,stride length,knee flexion and extension range and hip flexion and extension range were statistically significant(P<0.05),while the results of step frequency were not statistically significant(P>0.05).3.The contralateral limb in patients with lumbar disc prolapse compared with healthy volunteers ipsilateral limbs found that patients with the contralateral limb step length,stride length,stride frequency,range and knee joint flexion and extension after the hip flexor stretching range reduced obviously,stride length,stride length,stride frequency,range and knee joint flexion and extension after the hip flexor stretching range results difference had statistical significance(P<0.05);4.through correlation analysis,it was found that JOA,ODI and VAS scores were correlated with patient’s step length,stride length and the flexion and extension range of hip joint(p<0.05),but not with patient’s step frequency and the flexion and extension range of knee joint(p>0.05).ConclusionThis study found that gait of patients with lumbar disc herniation has obvious abnormalities,mainly including reduction of step length and stride length,cceleration of step frequency,reduction of flexion and extension range of knee joint and flexion and extension range of hip joint.Step length,stride length and hip joint tilt back angle are significantly correlated with JOA,ODI and VAS scores,indicating that the more severe the lumbar spine dysfunction,the more severe the pain,and the more obvious the gait abnormality.
