Impact Of Nusinersen Treatment On Measures Of Exercise Intolerance In Spinal Muscular Atrophy, David Uher, Ashley M. Goodwin, Darryl C. De Vivo, Jacqueline Montes, Carol Ewing Garber Facsm

International Journal of Exercise Science: Conference Proceedings

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder, marked by insufficient production of SMN protein, leading to motor neuron dysfunction. Although ubiquitously produced throughout the body, motor neurons and muscle cells are selectively impacted by decreased SMN, which has been linked to impaired oxidative phosphorylation causing altered metabolic function and exercise intolerance. Nusinersen, administered directly to the central nervous (CNS), is an approved therapy that increases SMN protein in an effort to restore motor neuron function. PURPOSE: To evaluate the impact of treatment on markers of exercise tolerance in children and adults treated with nusinersen is not known. …
