Comparative StudyPostural imbalance and vibratory sensitivity in patients with idiopathic scoliosis: implications for treatment.
Sporadic research reports of decreased proprioception and balance problems have been reported in subjects with idiopathic scoliosis, yet these sensory motor deficits have not been addressed in conservative clinical management programs. The purpose of this study was to compare both balance reactions and vibratory sensitivity (as an estimate of proprioception) in patients with idiopathic scoliosis (N = 24) and age-matched controls (N = 24). Balance was measured by the ability to pass a series of simple static and complex sensory-challenged balance tasks. ⋯ Although vibration sensitivity did not distinguish normal healthy individuals from individuals with idiopathic scoliosis, those with more severe scoliotic curves appear to have a high threshold to vibration. These balance and vibratory differences could either be interpreted as etiologic risk factors or as consequences of spinal asymmetry. In either case, given that curves can continue to progress even into the adult years, improving the ability to right the body with gravity could help maintain the balance of the spine despite structural asymmetry.
