Development of an Innovative Telerehabilitation System to Improve Handgrip Strength

Handgrip strength is an essential function of the hand to perform day-to-day tasks. People lose grip strength due to various factors such as aging, diseases, and other medical conditions. According to neuroplastic and physiological principles, grip strength can be improved using goal-oriented tasks or exercises repeatedly and consistently. People often fail to adhere to repeated movements, including grip strength exercises. Studies have shown that game-based rehabilitation has improved exercise compliance and functional outcomes. This article explains the design and development of an affordable smartphone-based telerehabilitation system that includes an innovatively designed grip strength device (eGripper) and a phone application to play games.
