Evolution of scoliosis in SMA type II in absence of modifying treatment

Partager sur

To address the lack of data on the course of scoliosis without treatment that could be used as a benchmark for clinical trials or modifying treatment, an Italian team conducted a retrospective study in 84 people with SMA type II.

  • The mean scoliosis angle was 46°, with those aged seven years or less being significantly lower than those aged eight years or more.
  • There was also a correlation between Cobb angle and motor function, with the former being higher in children with lower Hammersmith motor scale scores.
  • The mean annual progression of scoliosis was 5.63°.
