Self-Administered Gaming and Exercise at Home (SAGEH)

"Participants in the G2 group will use the Twirlstone (knob-like) device to play a videogame called Nono's World. The Twirlstone is an electromechanical device that resembles a knob and a standard joystick (identical to the discontinued Atari CX-20 Controller). The knob can rotate or move in a push-pull fashion. To control the game's character (an axolotl called Nono), a signal about the knob motion is relayed to the computer wirelessly. This device has been certified by Johns Hopkins University's Clinical Engineering Services, where it was deemed less than minimum risk. The game has been custom built to allow participants to take control of the character using subtle manipulative finger movements to accomplish game-like tasks.~The investigators will use portable communication devices to carry out telemedicine sessions. All devices and are low-power battery-operated tools for encouraging hand movement and the components are approved for use in the commercial market."

"Participants 5 daily sessions over 3 weeks consisting of self-administered, unsupervised occupational therpay. Additionally, participants will have 2, \<15 minutes telemedicine check-in appointments (not standard of care) provided by a licensed occupational therapist for the purposes of assessing safety and providing guidance for the unsupervised sessions. The intervention will focus on stretches, warm-up and strengthening exercises aimed at improving hand function.~The investigators will use portable communication devices for the purposes of carrying out telemedicine sessions.
