The NESS H200, which has been deemed a “miracle” by some stroke patients, helps send signals to the hand, which then allows patients produce a “grip” so they can perform everyday functions which became difficult after the stroke.  Taken for granted by healthy individuals, tasks like opening a door or holding a book are often quite hard or even impossible for those suffering from stroke-induced paralysis.

Occupational therapist Lisa Finnen talked about the device in an article published by ZeeNews.

However, there may be some goals that may not be as functional, they may be as simple as the person just being able to open the hand for hygiene purposes and to maintain skin integrity and just to even incorporate the hand into exercise. And for a lot of these folks there just hasn't been much out there to help them to do that," Finnen says.

The device is worn on the forearm and emits electrical impulses to the peripheral nerve muscle groups of the forearm and hand. Use has shown that it may also help circulation in the upper arm. 

Finnen says that the NESS H200 can be used for almost all stroke patients suffering from paralysis and may be used in the future to treat spinal cord injuries.  She notes that “implants could potentially be implanted into some of these paralyzed muscles and provide stimulation without having to use an external device."
