title: Reliability of transcutaneous oxygen tension measurement on the back of the hand and complex regional pain syndrome after stroke.
abstract: OBJECTIVE
  To verify the reproducibility of measurement of transcutaneous oxygen tension (TcPo(2)) on the back of the hand in control subjects and stroke patients in the assessment of the complex regional pain syndrome type I (CRPS I).
  
  
  METHODS
  Case series study.
  
  
  METHODS
  Physical medicine and rehabilitation department at a university hospital.
  
  
  METHODS
  Eighteen control subjects, 30 stroke patients without CRPS I, and 12 stroke patients with CRPS I.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  TcPo(2) was measured on the back of hands on 2 consecutive days using a polarographic technique. The reproducibility was evaluated by using the intraclass correlation coefficient (ICC) and the coefficient of variation.
  
  
  RESULTS
  In the controls, the values of TcPo(2) were not reproducible, with an ICC of.51 (95% confidence interval [CI],.23-.72). Similarly, in the hemiplegics with and without CRPS I, TcPo(2) was not reproducible, with an ICC of.43 (95% CI, -.15 to.74) and.69 (95% CI,.45-.84), respectively. The differences between the 2 upper limbs were even less reproducible in each population.
  
  
  CONCLUSIONS
  Measurement of TcPo(2) on the hand using our procedure did not seem to be sufficiently reproducible for application to a pathology such as CRPS I.
