Effect of Graded Activity with Interferential Therapy on Pain, Lumbar Range of Motion And Functional Activities among Subjects with Non Specific Low Back Pain

Background: Non-specific low back pain (NLBP) is a common and debilitating condition often characterized by restricted spinal mobility, particularly in extension. Graded activity exercise, a rehabilitation technique, aims to manage musculoskeletal pain by gradually increasing physical activity based on an individual’s current abilities and pain levels. Interferential therapy (IFT), a widely used electrotherapy modality, utilizes beat frequencies to relieve pain, reduce edema, and enhance joint range of motion (ROM). Aim & Methodology: The purpose of this study was to assess the impact of combining graded activity exercises with interferential therapy on pain, lumbar ROM, and functional activities in individuals with NLBP. The experimental study included 30 participants who met the inclusion criteria and were randomly assigned to a single treatment group. The treatment, consisting of graded activity exercises along with interferential therapy, was administered over 6 weeks. Pre- and post-treatment assessments were conducted using the Numerical Pain Rating Scale, Modified Schober’s test for ROM, and the Revised Oswestry Disability Index for functional activities. Results: The results showed significant improvements (p < 0.05) in pain levels, ROM, and functional performance after the treatment. Conclusion: The study concluded that graded activity exercises combined with interferential therapy are effective in alleviating pain, increasing lumbar ROM, and enhancing functional abilities in individuals with non-specific low back pain.
