Paralysis after a stroke can be alleviated: scientists figured out exactly how

Researchers from the Universities of Pittsburgh and Carnegie Mellon have successfully tested neurotechnology for...

spinal cord stimulation. The goal is to improve hand mobility in stroke patients in a short time. The technology will help stroke patients cope with routine tasks more easily.

Previously, spinal cord stimulation was used topain treatment. The authors of a new study tried a method for treating the consequences of a stroke. They used computer simulations and conducted preclinical testing in macaques. Then they received permission to optimize therapy for the treatment of people.

In a series of adapted tests, stimulation helpedpatients to perform tasks of varying complexity: move objects, open locks or canned food, clench and clench fists, raise arms above their heads, and even use a fork and knife to eat.

“By stimulating certain sensory nerves in the hands, wewe increase the activity of muscles that are weakened by a stroke, explains Douglas Weber, professor of mechanical engineering at the Institute of Neurology at Carnegie Mellon University. “It is important that the patient retains full control of movement: assisted stimulation reinforces muscle activation only when patients attempt to move.”

Worldwide, one in four people over the age of 25years may experience a stroke during their lifetime. 75% of them have problems with the functioning of the hands, which limits the physical autonomy of patients. There is currently no effective treatment for stroke-induced paralysis.
