Abstract
Non-Specific Low Back Pain (NSLBP) is often accompanied with movement limitations and can have produced some impact in wellbeing of life. It has garnered global attention due to its socioeconomic impact on communities. According to existing literature, there is no single superior treatment available for LBP. Treating LBP challenging due to the wide array of applications and treatment protocols. However, manual therapy has shown moderate to high evidence in effectively treating chronic LBP.
Mulligan SNAGs involve the therapist applied accessory passive glide to lumbar vertebrae concurrently active movement performed patient.
The aim of the study to assess the mode of action and potential for future applications in the therapy of CNSLBP.
Surface electromyography (SEMG) involves the recording of the electrical stimulus in the muscles of their motor units. It is used as one of the outcome measurement tools to detect and record electrical potentials from muscle fibres.
Objective:To investigate the impact of the Mulligan SNAGs on individuals with CNSLBP and overall effects in pain, ROM and EMG analysis.
Materials And Methodology:Forty subjects diagnosed with CNSLBP were selected, and informed consent was obtained. They splitted Group A experimental and Group B Control. Experimental group A received SNAGs, while control group B received Conventional Exercises. Each group about nine sessions in 3 weeks duration. The subjects evaluated using the Numerical Pain Rating Scale (NPRS), Modified Schober Test (MST) for range of motion, and Surface Electromyography (SEMG) on erector spinae muscles. Pre and post maximum voluntary contractions were measured.
Results:The experimental group showed significantly greater improvement in NPRS, lumbar flexion and extension compared than Group B Control, along with P value 0.001 (<0.05). EMG activity of the right and left erector spinae demonstrated significantly higher improvements in the Group A experimental compare than Group B control.
Conclusion:Mulligan SNAGs were more effectively improve ROM and reduce pain compare than conventional therapy among CNSLBP subjects.
