Spinal Cord Stimulation: A Promising New Treatment for SMA

A new therapeutic approach could mark a significant breakthrough in the treatment of spinal muscular atrophy (SMA), a genetic neurodegenerative disease that affects motor neurons and leads to progressive muscle weakness. Researchers at the University of Pittsburgh have developed a minimally invasive intervention that electrically stimulates sensory spinal nerves to restore neural function and improve patients' mobility.

This drug-free treatment relies on epidural spinal cord stimulation to enhance the activity of motor neurons, the nerve cells responsible for communication between the brain, spinal cord, and muscles. In the first clinical trials conducted on three adults with SMA, the results have been promising. After just one month of stimulation, participants showed significant improvements in muscle strength and walking ability, regardless of the severity of the disease.

The innovative approach aims to counteract neural circuit dysfunction, which underlies SMA symptoms. Previously, motor neuron degeneration was considered irreversible, but this treatment appears to partially reverse the process, improving communication between the nervous system and muscles. Patients reported a significant increase in endurance and reduced fatigue, with some able to walk longer distances without tiring.

This research paves the way for new possibilities not only for SMA but also for other neurodegenerative diseases such as ALS and Huntington’s disease, which could benefit from similar technologies. The authors of the study, recently published in Nature Medicine, plan to continue exploring the long-term efficacy of spinal cord stimulation, aiming to test its applicability in a larger number of patients.
