Background and Objective of Study: Chronic Neck pain is the 2nd most prevalent musculoskeletal disorder seen in Physiotherapists after Low Back Pain. Awkward postures, movements while handling patients, lifting, shifting and mobilizing the patients have been found to be risk factors for chronic neck pain in Physiotherapists. Physiotherapists need to have a good grip strength while mobilizing and treating patients. Chronic pain has been known to have a deleterious effect on muscle strength. The current study intended to find the association of neck pain as measured by Visual Analogue Scale (VAS), Neck Disability as measured by Neck Disability Index (NDI) with grip strength measured by hand held dynamometer in Kilogram (Unit). Materials &Methods: 40 Physiotherapists working/practicing in different hospitals, clinics with chronic neck were selected for the study using Convenience Random Sampling. Readings were taken for neck pain, Neck disability and hand grip strength. Result & Discussion: Results of the study showed a significant negative correlation between neck pain and grip strength(r-0.35684) and neck disability and grip strength (r-0.419).Based on the results it can be concluded that Physiotherapists with chronic neck pain had reduced grip strength. Interference with ability of Nervous system to activate hand muscle through Motor Units may cause a reduction in Grip Strength and Grip Endurance. More over fear avoidance response as seen in patients with chronic neck pain for fear of injury leads to disuse atrophy and reduction in capacity to generate and retain force.
