The cranium, cervical spine, mandible, shoulder girdle complex are the biomechanical functional unit for maintaining natural head posture1. It is expected to conform to the physiological requirements associated with sight (visual axis), the vestibular balance system and hearing. In literature, this functional unit has been termed as "UPPER QUADRANT"2. Different components of this unit are linked to each other through musculoskeletal system forming a kinetic chain. Impairment in this musculoskeletal unit may produce at the various level such as; cervical, shoulder, elbow etc. however regardless or origin of site or unit affected eventually likely to the certain extent in long term. This may be one of the reasons for functional disability that person has to wean off from his occupation. This leads to workers absenteeism from his work, while on another side a person working environment itself can be the perpetuating risk factors for such impairment3. Impact of various factors in his occupation may predispose him to impairment and disability. Occupational safety and health administration exposure concern that there are disorders affecting wrist, tissue, arm and other anatomic areas as a result of ergonomic stress occurring from repetitive motions, forceful exertions, vibrations, sustained or outward positioning4.
