Abstract

PURPOSE:  Severe motor and intellectual disabilities syndrome (SMIDS) is a term used to describe a heterogeneous group of disorders with severe physical disabilities and profound mental retardation. Patients with SMIDS have spinal deformity in high incidence, and showed to multiple scoliosis curve pattern. The purpose of this study is to examine the correlation between spinal characteristics (including scoliosis curve pattern and respiratory function.

METHODS:  Thirty patients with SMIDS (M:F 18:12, Age, 33.5 ± 12.1, means ± SD)who were studied. All subjects were severe cerebral palsy, and were unable to sit independently. Spinal deformity were measured by Cobb Method (Cobb angles :CA) and Nash & Moe technique (vertebrae rotation grade :VRG). Scoliosis curve pattern were divided into three groups(thoracic, thoracolumbar and lumbar ) according to the different apical vertebrae by X-ray image. We measured tidal volume&, respiratory frequency observed during tidal breathing at static supine posture.

RESULTS:  CA and VRG, both were inversely correlated with tidal volume (CA:r=-0.71, p<0.01,VRG:rs=-0.59, p<0.01). CA and VRG, both were correlated with respiratory frequency(CA: r=0.67, p<0.01, VRG:rs=0.56, p<0.01). However, We did not find significant differences of respiratory function among curve patterns in patient with SMIDS.

CONCLUSION:  These results suggest that the spinal deformity restrictively affect respiratory patterns in patients with SMIDS. Scoliosis curve pattern did not affect respiratory function.

CLINICAL IMPLICATIONS:  To care to prevent spinal deformities especially in CA and VRG is very important in terms of maintaining respiratoy function.
