The device was called Myoshirt. It looks like a vest with cuffs for the forearms. The set includes a box containing all the technologies that are not used directly on the body.
The algorithm works using sensors embedded in the fabric and determines the user's intentional movements, as well as the additional force required.
The motor then shortens the cable in the fabric,which runs parallel to the user's muscles - a kind of artificial tendon - and thus performs the desired movement. All user actions can be tailored to individual preferences, the team says. Also, a person constantly monitors the situation and can turn off the device at any time.
The authors first tested Myoshirt inexperiment with 12 volunteers: ten people had no physical impairment, one had muscular dystrophy, and one had a spinal cord injury.
The results were promising:All participants can keep their hand suspended or heavy objects in their hand much longer thanks to Myoshirt. Endurance increased by about a third in healthy subjects and by about 60% in a participant with muscular dystrophy, and a volunteer with a spinal cord injury was even able to perform the exercises three times longer.
