Parkinson's Patient Able To Walk Again Without Problems After Spinal Implant 14
An anonymous reader quotes a report from The Guardian: Marc, 63, from Bordeaux, France, was diagnosed with the degenerative disease more than 20 years ago and had developed severe mobility problems, including balance impairments and freezing of gait. After receiving the implant, which aims to restore normal signaling to the leg muscles from the spine, he has been able to walk more normally and regained his independence. "I practically could not walk any more without falling frequently, several times a day. In some situations, such as entering a lift, I'd trample on the spot, as though I was frozen there, you might say," he said. "Right now, I'm not even afraid of the stairs any more. Every Sunday I go to the lake, and I walk around 6 kilometers [3.7 miles]. It's incredible."
The implant is yet to be tested in a full clinical trial. But the Swiss team, who have a longstanding program to develop brain-machine interfaces to overcome paralysis, hope that their technology could offer an entirely new approach to treating movement deficits in those with Parkinson's disease. "It is impressive to see how by electrically stimulating the spinal cord in a targeted manner, in the same way as we have done with paraplegic patients, we can correct walking disorders caused by Parkinson's disease," said Jocelyne Bloch, neurosurgeon and professor at the CHUV Lausanne University hospital, who co-led the work.
First, the team developed a personalized anatomical map of Marc's spinal cord that identified the precise locations that were involved in signaling to the leg to move. Electrodes were then implanted at these locations, allowing stimulation to be delivered directly into the spine. The patient wears a movement sensor on each leg and when walking is initiated the implant automatically switches on and begins delivering pulses of stimulation to the spinal neurons. The aim is to correct abnormal signals that are sent from the brain, down the spine, to the legs in order to restore normal movement. "At no point is [the patient] controlled by the machine," said Prof Eduardo Martin Moraud, of Lausanne University hospital. "It's just enhancing his capacity to walk." The study, published in Nature Medicine, found that the implant improved walking and balance deficits and when Marc's walking was analyzed it more closely resembled that of healthy controls than that of other Parkinson's patients. Marc also reported significant improvements in his quality of life.

Don't look at me like that. You knew what this was.

Imagine telling a crowd to disperse, and their legs just do it for them!

There are many impressive videos of people with Parkinsons responding almost perfectly to exogenous cannabanoids.
Presumably they tried that before a spinal implant, so it's looking like there might be two diseases that are both diagnosed as Parkinsons because the symptoms are the same with different root causes.
It also causes me concern for kids who are experimenting with such powerful medicines and assuming the result will always be beneficial.

Lots of modern medicines are derived from exotic plants, but this is not a well known tid bit.

Right!? The greatest kept super mega pharma secret, versions of cannabis actually cure everything, and they're absolutely scientific proof about it but they're all hiding it.
Just as much proof that beer is valid medication to relieve anxiety and assist people cope with this problem by being more relaxed. A little bit of truth making some really long stretches.
