Researchers developed a way to help people with amputation or paralysis regain limb control. Their optogenetic technique could offer more precise control over muscle contraction, along with a dramatic ...

In the last few decades, individuals with mobility issues have seen a flurry of advancements in neuroprosthetic devices, artificial systems that seek to replace a particular sensation or lost ability.

A project at MIT has investigated whether optogenetics could be a better way to drive muscle contraction in clinical treatments than traditional electrical stimulation. Published in Science Robotics, ...
