Exam 3 Non-Quizzies Flashcards

1
Q

what is the relationship between degrees of lateral curve deviation, axial rotation, and care?

A
  1. curves with 10-20 degrees of lateral deviation and a fixed angle of trunk rotation have scoliosis
  2. curves with 20-30 degrees of lateral deviation and a fixed angle of trunk rotation of 5 degrees require attention
  3. curves with 30-50 degrees of lateral deviation and a fixed angle of trunk rotation of 7 degrees require intervention as they have a 60% chance to worsen
  4. curves with greater than 50 degrees of lateral deviation have a 90% chance to worsen
