Rigid spine muscular dystrophy (RSMD) is a type of congenital muscular dystrophy characterized by weakness of the muscles of the torso and neck, which can affect the spine and cause breathing difficulties. Like all congenital dystrophies, the muscle weakness that marks RSMD is either present at birth or develops within the first few months of life.
There is currently no cure for RSMD, and management options focus on the relief of symptoms and improving quality of life.
Because RSMD also affects respiratory muscles, patients may need help with breathing, especially at night. Non-invasive ventilation, such as a BiPAP device, facilitates breathing by providing higher pressure during inhalation.
