Abstract
Background: Failed Back Surgery Syndrome (FBSS) refers to impairments
and disorders that develop or continue following one or more lower back
surgeries. This increasing clinical challenge highlighted a critical need for more
evidence-based neurological physical therapy techniques in the field. Purpose:
The purpose of this study is to examine how individuals with failed surgery for
a back condition respond to low-level therapeutic lasers (LLLT) and core
muscle training. Methods: The purpose of this study is to examine how
individuals with failed surgery for a back condition respond to low-level
therapeutic lasers (LLLT) and core muscle training. Results: Post-treatment,
both groups showed significant improvements in NPRS, ODI, and bilateral
SLR range of motion compared to baseline (P < 0.05). The mixed design 2 x 2
MANOVA revealed that the study group achieved significantly superior
outcomes compared to the control group (P < 0.05). Specifically, the study
group demonstrated greater reductions in pain and disability, alongside more
substantial increases in bilateral SLR range of motion. Conclusion: FBSS was
successfully managed by the combined LLLT and core training program,
which significantly reduced pain, functional disability, and SLR range of
motion
