The aim of this study was to evaluate the risk factors and clinical features of upper extremity musculoskeletal disorders (MSD) in mobile device users. A report analysis which included 59 subjects between the ages of 5 to 56 years, who were diagnosed to have a MSD affecting the upper extremities was done. All the patients underwent rehabilitation using a sequenced protocol. All the subjects reported pain in the thumb and forearm with associated burning, numbness and tingling around the thenar aspect of the hand, and stiffness of wrist and hand. 24 subjects had symptoms on the right side; 12 on left and 13 had bilateral symptoms. Correlation was found between hand dominance and MSD. 33 subjects complained of onset of symptoms following extensive text messaging. All the subjects were diagnosed to have tendinosis of Extensor Pollicis Longus and Myofascial Pain Syndrome affecting the 1st interossei, thenar group of muscles and Extensor igitorum Communis. 23 of the subjects were senior executives, among these 7 were CEO’s of major multinational companies in India. All the subjects recovered completely following the rehabilitation.
