Comparison of the effect of sling exercise and visual feedback exercise on the pain, muscle function and spinal mobility in chronic low back pain patients

Objective: This study investigated the comparison of the effects of sling exercise (SE) and visual feedback exercise (VFE) on pain, disability, muscle function, and spinal mobility on chronic low back pain(CLBP). Method: 23 patients with CLBP were randomized into two groups of 11 members in the SE group and 12 members in the VFE group. One group performed SE and the other group performed VFE, each for 50 minutes three times a week for eight weeks. Pain intensity was measured by the Visual Analog Scale(VAS) and the Oswestry Disability Index(ODI). Transversus Abdominis(TrA) endurance was measured by the Pressure biofeedback unit. Spinal mobility was measured by the Spinal mouse. Measurements were made at baseline, and eight weeks after the intervention. Results: Significant differences in VAS and ODI were observed within both groups and SE group experienced a greater decrease in pain and disability. TrA endurance for each group showed significant change eight weeks after the intervention(p<.05). VFE group experienced a greater increase in TrA endurance. Spinal mobility increased for both groups in the lumbar flexion angle, but significant differences were observed the SE group in the lumbar extension angle. Conclusion: SE and VFE were effective in decreasing pain, disability, and increasing TrA endurance and spinal mobility in chronic low back pain patients. SE was more effective in pain, disability, lumbar segmental stabilization while VFE was more effective in TrA endurance.
