Scientific Background

Recent research indicates that targeted hand function training enhances neuroplastic changes in the brain. We are applying deep research in neuroplasticity combined with personalized and targeted hand rehabilitation technology to aid in motor control recovery.

Current Research

Scientists at Baycrest Hospital, McMaster & Laurentian Universities are testing experimental hand motor therapies for post stroke upper limb impairment using the MyHand System. Some trials are on-going, check back here to see the latest recruitment posters to get in touch with these reaserchers. Projects are updated reguarly.

The ability of the brain and spinal cord to change

CONCEPT

Neuroplasticity refers to the ability of the brain and spinal cord to change. At one time it was just a theoretical concept, it is now proven to have a huge impact on individuals with traumatic brain injury or stroke. "Scientists have shown the brain healing impact of neuroplasticity in both animals and humans." There are a number of fascinating real-life stories that illustrate the concept of neuroplasticity.

STUDY

"An August 2018 NPR Science Friday show highlighted two captivating real-life stories." First, a boy who lost 1/6th of his brain, and has learned to live with it beyond and against everyone’s expectations. Second, healthy humans with two functioning arms, to whom a bionic arm (third arm) was attached at their neck, and connected to their brain using neural links (nerves) normally not used for hand-related activities. A total of 14 individuals participated in this study, and all of them were able to perform a two handed task (with their two healthy hands), while the bionic arm was able to hold a bottle.
