Demographics, age at the first nusinersen dose, total administrations, and Children\u2019s of Philadelphia Infant Test of Neuromuscular Disorders scores were collected.

There was a significant correlation between Children\u2019s of Philadelphia Infant Test of Neuromuscular Disorders score and the number of nusinersen administration ( r\u2009=\u20090.539, p\u2009=\u20090.05). The correlation between Children\u2019s of Philadelphia Infant Test of Neuromuscular Disorders score and patient age ( r\u2009=\u20090.361) or the time of first nusinersen dose ( r\u2009=\u20090.39) was not significant ( p\u2009=\u20090.076 and p\u2009=\u20090.054, respectively). While 93.1% had scoliosis, 69% had pelvic obliquity, and 60.7% had hip subluxation, these conditions showed no significant association with patient age, total nusinersen administrations, age at the first dose, or Children\u2019s of Philadelphia Infant Test of Neuromuscular Disorders scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Disease-modifying therapy provides significant improvements in overall survival and motor function in spinal muscular atrophy type 1.
