Myosleeve is a wearable medical device for the motor rehabilitation of epicondylitis (tennis or golfer’s elbow). Based on High Density Surface Electromyography, this smart device not only records muscular activity, but also extracts neuromuscular data so that therapies can be personalised using machine learning, which is extremely useful for clinicians. In addition, it provides interactive feedback that keeps patients involved. As a result, the device allows for remote rehabilitation, ensures exercises are carried out correctly, and helps speed up treatment results.
