Many studies have been conducted on the use of powered orthotics or powered exoskeletons and their relation to remediating movement issues of individuals with poor muscle control due to muscle or brain atrophy in genetic or lifestyle effected individuals.
In Summary, persons effected with poor walking problems from muscle problems either due to genetic issues or lifestyle related issues such as ongoing drug use can find temporary remedy by training their muscles using powered exoskeleton devices by wearing them and using them as support for further muscle training to halt the ongoing progression of further muscle breakdown problems.
