title: A randomized trial of the traditional sitting position versus the hamstring stretch position for labor epidural needle placement.
abstract: BACKGROUND
  Anecdotal and experimental evidence suggest that a sitting position with maximum knee extension, hip adduction, and forward lean (hamstring stretch position) may produce better reversal of the lumbar lordosis than a traditional sitting position.
  
  
  METHODS
  In a randomized trial during initiation of epidural labor analgesia, we compared the traditional versus hamstring stretch positions. The primary outcome was the number of needle-bone contacts.
  
  
  RESULTS
  The groups were equivalent with respect to the number of needle-bone contacts.
  
  
  CONCLUSIONS
  The hamstring stretch position is equivalent to the traditional sitting position in terms of the number of needle-bone contacts encountered when placing labor epidural needles.
