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