• Purpose Spinal muscular atrophy (SMA) is a rare, autosomal-recessive disease characterized by progressive muscular atrophy and weakness resulting in substantial disability and short life expectancy. The objective of this cross-sectional study was to assess health-related quality of life (HRQoL) of adults with SMA in Germany in the era of disease-modifying therapy. Methods Adults with SMA were recruited via the German national TREAT-NMD SMA patient registry. HRQoL was measured using the EQ-5D-5L, the Health Utilities Index Mark III (HUI), and the Short Form (36) Health Survey (SF-36). Estimates were stratified by current best motor function of the lower limb and trunk (i.e., non-sitter, sitter, and walker) and SMA type (i.e., type I, II, and III). Results A total of 82 adults with SMA (mean age: 42 years, 51% female) self-completed the study questionnaire. The mean EQ-5D-5L utility was estimated at 0.5135 (range across subgroups: 0.31–0.99), mean EQ-VAS at 69.71 (64.67–90.00), mean HUI-derived utility at 0.3171 ( – 0.02–0.96), mean SF-6D utility at 0.6308 (0.58–0.65), and mean SF-36 Physical Component Summary and Mental Health Component Summary scores at 33.78 (9.92–53.10) and 53.49 (21.02–72.25), respectively. Conclusions We show that adults with SMA experience considerable impairment across a wide range of health dimensions, including mobility, dexterity, pain, and emotional well-being. However, our results exhibit non-trivial variability across clinical subgroups and HRQoL measures. These data contribute to our understanding of the subjective impact of living with a severely debilitating neuromuscular disease, such as SMA.
