Introduction

Preventing WRUMSDs can notably disturb or create discomfort in activities of the important body regions performance because upper extremities such as shoulder, neck, hand and arm are vital parts of the body (Alipour, 2008).

Materials and methods

Samples for this study was obtained from the operational workers I.e. Technical workers in an oil and gas processing plant. Main focus was those who were working in confined work space and those who were working on monotonous pace for longer period.
