Researchers testing vibrating technology to help stroke patients

Nearly 800,000 people in the United States have a stroke each year, according to the Centers for Disease Control and Prevention. A common challenge for stroke patients in recovery is spasticity, or severe muscle stiffness. Spasticity affects roughly a quarter of all stroke patients.

He still deals with spasticity. The severe muscle spasms keep his arm stiff, his wrist chronically curved and his hand firmly in a fist. Lansberg and researchers at Stanford’s mechanical engineering CHARM Lab run by Professor Allison Okamura just published research on a medical glove to counteract spasticity.

“We always use the same amount, the same intensity of the vibration. But absolutely, you can kick it up and kick it down. You can also change the patterns of vibration, and maybe how intense it is on the palm versus another part of the hand,” said Okamura.
