EFFECT OF DIFFERENT WAVE-LENGTHES OF LASER IN THE TREATMENT OF LOWER BACK MECHANICAL LOW BACK PAIN at the Neelain University, clinic of physiotherapy from June 2018 to June 2021

Abstract

Abstract Background: Myofascial pain syndrome (MPS) is one of the most frequent causes of chronic musculoskeletal pain, the pain is caused by myofascial trigger points (TPs) and their associated reflexes result in persistent musculoskeletal pain in lower back. Low level laser therapy (LLLT) is used by some physiotherapists to treat various musculoskeletal condition. LLLT is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration. LLLT is believed to affect the function of connective tissue cells (fibroblasts), accelerate connective tissue repair and act as an anti-inflammatory agent. Lasers with different wavelengths, varying from 630 to 905 nm, are used in the treatment of musculoskeletal disorders. The aim of this study to investigate the effects of different laser wave-lengths (650 and 905) in the treatment of patients with lower back myofascial pain syndrome Material and methodology: This study was conducted on thirty patients with lower back myofascial pain syndrome 18 males and 12 females their age ranged from 24-55 years old divided randomly into three groups of equal number of patients, group (A) 10 patients received traditional physiotherapy, group (B) 10 patients received traditional physiotherapy and LLLT 650 nm, group (C) 10 patients received traditional physiotherapy and LLLT 950 nm In this study pain assessed by (VAS), Functional disability by Oswestery disability questionnaire, flexion ROM by modified schober test and statistical analysis by SPSS. Results The current study found that combination of LLLT (905 nm) with traditional physiotherapy (US, TENS, IR and therapeutic exercise), have better effect in short term at increasing the functional ability (p=0.005) and flexion range of motion of the back and has great effect at decreasing the pain degree(p=0.00) than traditional physiotherapy alone or traditional physiotherapy combined with LLLT (650 nm).
