A new study shows that spinal cord stimulation can improve muscle function in people with spinal muscular atrophy (SMA). Three participants in a pilot study were able to stand and walk more easily after an implanted device zapped their spinal cord.

The Pitt researchers implanted electrodes over the lower spinal cord of three adults with SMA and tested their muscle strength, fatigue, range of motion and changes in gait and walking distance when the device was firing and when it was turned off. All three participants significantly increased how far they could walk in six minutes, and one who initially couldn’t stand from a kneeling position could by the study’s end, Capogrosso said. And McCullough’s gait changed so that each step was about three times longer.
McCullough said even when the stimulator was turned off, some nights his legs “would just feel supercharged.”

Ultrasound Brain Stimulation Shows Promise for Treating Mental Health ConditionsA new National Health Service (NHS) trial is exploring the use of ultrasound to directly influence brain activity and treat mental health conditions like depression and anxiety. The trial will evaluate a brain-computer-interface (BCI) device that uses ultrasound to both monitor and stimulate specific clusters of neurons. If successful, this non-invasive approach could revolutionize the treatment of mental health disorders.
