Story summary

Researchers paired a sub-kilogram knee-mounted robot with a video game to train six Chinese children aged six to ten with spinal muscular atrophy.
The robot, weighing under 1 kg, did not assist movement but made kicking harder, forcing muscles and nerves to cooperate, and after weeks the children could stand up from a chair.
Researchers observed increased muscle mass and strength in the participants after only a few weeks of gameplay.
