A Comparative Study on the Efficacy of Low Level Laser Therapy (LLLT) of Wavelength 905 NM and 808 NM in Management of Chronic Low Back Pain

Background: low back pain (LBP) is one of the most common musculoskeletal disorders whichare highly prevalent among the general population. Management of this disorder includes numerousinterventions which depend on severity of pain. Laser therapy is a non-invasive method to help reducemusculoskeletal disorders like chronic low back pain. This study aims to evaluate the efficacy of lowlevel laser therapy with wavelength 905 nm & 808 nm.Method: The participants received low level laser therapy with wavelength 905 nm & 808 nm once aday for 15 days. Stretching, strengthening and core exercise are also encouraged on the same days toimprove the lower back mobility and stability.Conclusion: The comparison of pain shows an average improvement of 3.20 ± 0.99 and 2.26 ± 0.44and disability shows an average improvement of 10.67 ± 5.48 and 10.22 ± 4.72 in 905 nm & 808 nmrespectively. The findings show that, after 15 treatment sessions, Laser therapy with 905 nm & 808 nmare effective for chronic low back pain. But 905 nm LLLT had a better clinical implication than 808nm LLLT.
