Quality of Life Assessment in Romanian Patients with Spinal Muscular Atrophy Undergoing Nusinersen Treatment

Spinal muscular atrophy (SMA), identified over a century ago, is characterized by severe muscle wasting and early mortality. Despite its rarity, the high carrier frequency of the responsible genetic mutations and the variability in its manifestations make it a significant research focus. This prospective cross-sectional descriptive study evaluated health-related quality of life (HRQoL) across eight health domains in 43 Romanian SMA patients treated with nusinersen, using the SF-36 questionnaire to analyze influencing factors. The survey was conducted online with informed consent, and the data were analyzed using MedCalc software, employing both parametric and non-parametric statistical tests for accurate interpretation. The results revealed significant variations in HRQoL. Most patients were non-ambulatory (74.4%), reflecting SMA's impact on mobility. Urban residents reported better outcomes, particularly in physical functioning (
