Background and Aims: The aim of present study was to evaluate the effect of Postural Restoration Institute (PRI) training on lower limb kinematics during walking in middle-aged subjects with discogenic low back pain.
Materials and Methods: In this prospective observational semi-experimental study, 42 people participated in three groups of people with low back pain (14 as intervention and 14 as control group) and 14 healthy individuals (without low back pain). Kinematic data was recorded by Seven cameras of Qualisys with a frequency of 100 Hz in pre-test and post-test. Analysis of variance with repeated measures was used in SPSS software version 23 with a significance level of 0.05.
Results: The results showed that people with low back pain in both intervention and control groups walked at a slower velocity, lower cadence as well as shorter step length in comparison with healthy individuals for both right and left limbs, while significant increase was determined after the training intervention. Furthermore, the significant changes of the range of motion observed for the pelvis in sagittal and frontal plane, the right hip in the horizontal plane, the right ankle in the frontal plane, the left hip joint in the sagittal and horizontal plane as well as the left ankle in the sagittal plane between the healthy group and the two control and intervention groups. By applying PRI, the range of motion difference of the pelvis on the sagittal plane, the right ankle on the sagittal plane, the left hip joint on the frontal plane and the left knee on the sagittal plane was minimized between the healthy group and the intervention group.
Conclusion: The findings of the present study confirmed the effectiveness of using the exercises of Postural Restoration Institute in improving range of motion and increasing the velocity and step length of walking as biomechanical indicators of treatment and performance management of people with chronic low back pain.
