A treatment that has restored the movement of patients with chronic Parkinson's disease has been developed by Canadian researchers.

Axar.az reports citing foreign media.

Previously housebound patients are now able to walk more freely as a result of electrical stimulation to their spines.

A quarter of patients have difficulty walking as the disease wears on, often freezing on the spot and falling.

Parkinson's UK hailed its potential impact on an aspect of the disease where there is currently no treatment.

Prof Mandar Jog, of Western University in London, Ontario, told BBC News the scale of benefit to patients of his new treatment was "beyond his wildest dreams".
