Repeated stimulation treatment can restore movement to paralyzed muscles
Conducted at the BioMag laboratory at the Helsinki University Hospital, a new patient study could open a new opportunity to rehabilitate patients with spinal cord damage. In a new study which two patients with spinal cord injuries received a form of treatment that combined transcranial magnetic stimulation with simultaneous peripheral nerve stimulation given repeatedly for nearly six months.
Paralyzed men move legs with new non-invasive spinal cord stimulation
This image shows the range of voluntary movement prior to receiving stimulation compared to movement after receiving stimulation, physical conditioning, and buspirone. The subject’s legs are supported so that they can move without resistance from gravity. The electrodes on the legs are used for recording muscle activity.

Five men with complete motor paralysis were able to voluntarily generate step-like movements thanks to a new strategy that non-invasively delivers electrical stimulation to their spinal cords. The strategy, called transcutaneous stimulation, delivers electrical current to the spinal cord by way of electrodes strategically placed on the skin of the lower back.
Nerve Regeneration: Everyone does it, but you
Dogs do it, frogs do it, and even whales do it! No, this isn’t everyone poops. I’m talking about regrowing nerves after an injury and sadly, we don’t do it… yet. Now, thanks to a small molecule that may be able to convince damaged nerves to not just grow, but effectively rewire circuits, that all could change. Such breakthrough could eventually lead to therapies for the thousands of Americans with severe spinal cord injuries and paralysis.
More BIG News for Spinal Cord Injuries

It seems like lately we have been reporting left and right about people suffering from paralysis, and for good reason! Today I’m happy to report even more new research that offers hope for people suffering from spinal cord injury.
In a new study published in Brain [a journal of neurology] researchers used adult patients who suffered different spinal cord injuries. Two had feeling in the extremities, but could not move them, while the other two had neither feeling nor could they move their extremities.
Scientists cure Muscle Paralysis in Mice

Searching for a new way to cure paralysis, a team of scientist has come up with a remarkable and off the wall idea. This discovery comes out of the labs at the University College London. The team, lead by Linda Greensmith, used stem cells and optogenetics to control leg muscles in mice and completely circumvent the nervous system in the process.
For those of you who are not familiar with Optogenetics [and really, why would you be familiar with it?] here is a overly simple rundown of what we are talking about.
