Outcome of Mulligan’s NAGs Mobilization Technique along with Conventional Physiotherapy for Patients with Cervical Spondylosis: A Randomized Controlled Trail

Abstract

Background: Cervical spondylosis is a chronic, age-related degenerative condition of the cervical spine, impacting vertebrae, intervertebral discs, and spinal canal contents, including nerve roots and the spinal cord. It may involve disc herniation, bone spurs, and degenerative changes in facet joints and ligaments (Kuo & Tadi, 2023). Objectives: This Study aimed to exprement the outcome of the Mulligan’s mobilization technique NAGs along with conventional physiotherapy for pain, ROM, MS aad also functional ability of the patients with cervical spondylosis. Methodology: Experimental study design was used in this study. 30 patients with Cervical Spondylosis were randomly allocated into two groups from outdoor musculo-skeletal unit, CRP. Among them 15 patients were assigned into Exprimental group received Mulligan's NAGs with conventional physiotherapy and another 15 into control group received only conventional physiotherpy. Mulligan’s mobilization NAGs were performed at 2-3 repetions in 1 sec (for fewer than 6 repetitions) with 3 sets. Single blind procedure was used during data collection. Outcome measurement tools: Visual Analog Scale (VAS) was used to measure pain and universal goniometer to measure ROM, manual muscle testing (OXFORD Grade) to measure muscle strength and NDI to measure neck disability. Results: On comparing control group and exprimental group for post-treatment VAS score (p= 0.002), NDI score (p= 0.009) and overall ROM results showed a significant difference (P < 0.05) in improvement in terms VAS score, ROM and NDI score. Muscle strength (ms) improved within groups, but between groups results showed similar improvements, with no significant difference, where (P > 0.05). Discussion: The overall study proved that Mulligan’s NAGs mobilization with conventional physiotherapy is effective in improving ROM, reduciong Pain and decreasing the disability level except in muscle strength, in which showed no additional benefit in treating cervical spondylosis (CS) patients.
