Researchers investigated whether adolescents with type 2 and type 3 spinal muscular atrophy experienced sleep disorders.
The study involved 85 people between the ages of six and 25 years with type 2 and type 3 SMA. Researchers assessed the participants via the Sleep Disturbance Scale for Children and the Hammersmith Functional Motor Scale Expanded.
Sleep Medicine published the study.
Here are five things to know:
1. Of the children, 16.4 percent had an abnormal total sleep score.
2. Also, 16.7 percent of the children had an abnormal score on at least one SDSC sleep factor.
3. The researchers didn't find an association between sleep disturbances and functional level, as represented by the SDSC and HFMSE scores.
4. The study revealed, however, that the SDSC total score correlated with the "ability to half roll on both sides and to roll from prone to supine on the HMFSE."
5. The researchers concluded sleep disorders are "common in children with SMA."
