Vest vibrations may cut lung infections in ALS patients

This pilot study tested whether adding a vibrating chest vest to a standard cough-assist machine could reduce lung infections and hospital stays in people with ALS who use breathing support. Fourteen patients were randomly assigned to use either the vest plus cough assist or the cough assist alone for three months. The goal was to see if the vest helps clear mucus better and lowers the need for antibiotics or hospital visits.
