Abstract: The study was focussed on thumb movements and the associated muscles while operating mobile phones of three different sizes. The three targeted muscles were FDI (First Dorsal Interrosei), APB (Abductor Pollicis Brevis) and Extensor Digitorum muscles. An EMG was used for monitoring the muscle activities which was connected to the software installed in the computer. A total of eight subjects, four male and four female were selected for the experiment within the age range of 19 to 33 years. Subjects were given tasks like scrolling, tapping and typing which ensured maximum extension and maximum flexion of the thumb. The sequence of mobile use and tasks was randomized using Minitab statistical software. After sufficient data collection, analysis was done which concluded the project on the optimum screen size of 5.7 inches for most of the subjects.
