- The frequency of sleep disorders in spinal muscular atrophy (SMA) is explored
- The Sleep Disturbance Scale for Children and the Hammersmith Functional Motor Scale Expanded were used.

A total of 85 young persons (6–25 years of age) with type 2 and type 3. SMA were assessed using the Sleep Disturbance Scale for Children (SDSC), a scale assessing different sleep factors, and the Hammersmith Functional Motor Scale Expanded (HFMSE), a scale evaluating motor impairment.
