Gloves created to increase hand strength without any training for patients

According to The Asahi Shimbun, Nara Medical University has teamed with socks maker and seller Mikasa Inc. to develop gloves designed for patients with Parkinson’s disease and athletes to strengthen the muscles of their fingers.
The handwear is woven in a way that its back side becomes smaller so that the wearer’s fingers are constantly pulled. Donning them will allow users to improve their manual functions unconsciously through daily-life motions.
A team of the university’s researchers had subjects suffering from Parkinson’s disease, marked by muscular rigidity and other conditions, wear the gloves as an experiment for five days. They were then compared with patients who did not wear the gloves.
