title: Comparative study of risk factors for skin breakdown with cervical orthotic devices: Philadelphia and Aspen.
abstract: OBJECTIVE
  To compare risk factors for skin breakdown between Philadelphia and Aspen cervical collars.
  
  
  METHODS
  Crossover design. Twenty healthy volunteers wore Philadelphia and Aspen cervical collars in random order. Occipital pressure, relative skin humidity, and skin temperature measured at 0 and 30 minutes. Paired t-tests compared changes between collars from 0 to 30 minutes.
  
  
  RESULTS
  Occipital pressure and skin temperature were not statistically different between collars. Relative skin humidity increased more in Philadelphia (29% +/- 17%) than Aspen (8% +/- 9%), p < 0.001.
  
  
  CONCLUSIONS
  Aspen resulted in lower relative skin humidity.
