Abstract
Background: To our knowledge, there are no publications that have evaluated physical activities in relation to the etiology of AIS other than sport scoliosis (1,2) so we undertook a study to assess the physical activities of patients with progressive AIS from their first year to early teens and compared these with those of a control group.
Methods: All 156 children in this study had to adhere to the following 6 criteria:- born full term, fed well as infants, achieved their milestones, no hospital visits except for sports injuries, no family history of a scoliosis and no back pain (prior to diagnosis in the patient group). We compared 79 consecutive patients (girls 66, boys 13) diagnosed as progressive AIS (62 of whom subsequently had a spinal fusion) with a control group of 77 subjects (girls 66, boys 11) of similar age, gender, race and socioeconomic status. A structured history was obtained from the mother and child of each group average time taken to obtain the history was 47 minutes. Each child was examined for toe touching and vertical symmetry of spinous processes whilst standing. The findings suggest a relation between physical activities or the lack of them and the development of progressive AIS.
Results: There is a significantly increased odds of AIS in those who were introduced to a swimming pool within the first year of life (p=0.001), did not attend gymnastics/ karate classes (p=0.005), did not attend dance classes (girls only, p=0.045), did not have horse riding classes (p=0.003), did not go skating (< 0.001), and who could touch their toes (p=0.011). No association is found with playing football/hockey or regular swimming at the age of 10 years.
Conclusion: Progressive AIS is positively associated with an early introduction to swimming and ability to toe touch. Spinal asymmetry was noted in the controls. AIS is negatively associated with participation in dance, skating, gymnastics/karate and horse riding classes. Is it possible that children who develop AIS have a longstanding proprioception defect which makes them less likely to participate in sporting activities? If so, by encouraging children to participate in sport might we increase their proprioception abilities and make those at risk less likely to develop spinal asymmetry which may progress to a scoliosis requiring surgical correction?
