Objective of study will be to compare effects of Cailliet and Kendall exercises on pain, functional movement and disability in non-specific neck pain.This randomized clinical trial will be conducted at Good Hands Physiotherapy Clinic, Shahdara Lahore. Sample size of study will be 36. Participants will be randomly divided into two groups Group A and Group B. We will include patients with age group between 25 to 40 years, both genders having localized pain or stiffness in cervical spine for more than 3 months after exclusion of upper limb radiculopathy. Group A will receive Kendall exercises regime and Group B will receive Cailliet exercises regime. Both groups will receive baseline treatment including hot pack and Transcutaneous Electric Nerve Stimulation (TENS). Short term effects would be assessed after treatment for 3 sessions per week on alternate days for 4 weeks. Patients will be assessed by Numeric pain rating scale (NPRS) for pain, Selective Functional Movement Assessment (SFMA) for functional movement and Neck Disability Index (NDI) Urdu version for Disability. Analysis will be done by statistical package for social sciences SPSS 25.

Pain felt in an area circumscribed superiorly by the superior nuchal line, laterally by the neck's lateral borders, and inferiorly by an imagined transverse line passing through the T1 spinous process is defined as neck pain. An acute or chronic cervical and shoulder girdle issue originating from the occiput of the head to the spine of the scapula, with or without limiting cervical range of motion, and unrelated to any past history of infection or fracture can be characterized as non-specific neck pain. One of the most common musculoskeletal issues that impairs general population function and results in disability is neck pain. The cervical spine is a complicated biomechanical system made up of at least 20 pairs of muscles, many of which have similar roles, and countless degrees of flexibility for each joint. However, the etiology and basic pathology of neck pain are still unknown. Around the world, 330 million people experience some form of neck pain with mean estimates of 7.6% prevalence (range, 5.9-38.7%), 37% annual prevalence (range, 16.7-75%), and 48.5% lifetime prevalence (range, 14.2-71%).

There have been contradictory findings from earlier studies about the optimal management of neck pain. While some contend that exercise leads to greater results, others support the efficacy of conventional therapy. Comparing the short-term benefits of the exercise programs designed by Cailliet and Kendall, in order to ascertain which method produces better results in terms of symptom relief and pain reduction. By getting empirical data on the short-term impacts of exercise treatments, the study will advance evidence-based practice. Healthcare practitioners can rely on this information to make well-informed decisions and recommendations because it will provide scientific proof on their safety and efficacy. This will support the use of a more standardized and empirically supported approach in the treatment of generalized neck pain symptoms associated with the neck musculature.
