This study will be a randomized controlled trial.Non-probability convenient sampling will be used to collect the data. Sample size of 44 subjects with age group between 20-45 years will be taken. Data will be collected from the patients having present complaint of nonspecific Neck pain. Outcome measures will be taken using Numeric pain rating scale (NPRS) for pain, Neck Disability Index (NDI), Muscle endurance by Muscle endurance test using stopwatch and Universal Goniometer (GU) for Range of motion. An informed consent will be taken. Subjects will be selected on the basis of inclusion and exclusion criteria and will be equally divided into two groups by random computer generated numbers method. Group A will receive first and second rib mobilization, and Group B will receive conventional treatment. Outcome measures will be measured prior and after 4 weeks. Data will be analyzed by SPSS version 25.

the effect of First Rib Mobilization in Mechanical Neck Pain with Radiculopathy for Pain Relief in which fifty patients with age between 21- 60 years, who fulfilled the study sample selection criteria were registered in the study. After sample selection of 50 subjects (by scientific calculator) by using convenient sampling technique, a written consent was signed from each participant before any assessment and management. All subjects were treated by applying Maitland grade I, II first rib mobilization for a session comprising on 20 minutes. The subjects were treated thrice in a week for next 2 weeks. The participants were assessed before and after treatment. Numeric Pain Rating Scale (NPRS) was used to record pain severity level. A self-structured validated questionnaire was used to collect the demographics. Pain was assessed before and after first rib mobilization by using paired sample t-test was done to see the changes in the mean pain score. The study concluded that First Rib Mobilization was an effective treatment for subjects with mechanical neck ache and radicular symptoms.

Despite the extensive research on non-specific neck pain (NSNP) and various therapeutic interventions, there is a notable gap in the literature regarding the specific effects of first and second rib mobilization on pain, range of motion, muscle endurance, and disability in patients with NSNP. While studies have explored manual therapies, proprioceptive exercises, and virtual reality as complementary interventions, the direct impact of rib mobilization, especially involving both the first and second ribs, remains under-investigated. Additionally, most existing studies focus on short-term outcomes, and there is limited evidence on the long-term effects of rib mobilization techniques.
