Q

What is double crush syndrome?

A
  • an asymptomatic site of peripheral nerve compression that predisposes that nerve for increased risk of injury at a different location

Q

Is nerve gliding appropriate for management of a nerve disorder?

A
  • it can be. There is debate on whether it does what it is supposed to do
  • Should be considered on an individual basis depending on the injury. Could theoretically be helpful or detrimental depending on the structural situation

Q

What are 4 tests with sens/spec data for a cubital tunnel syndrome (ulnar neuritis?

A
  • Tinels
  • Elbow flexion test: pt flexes elbow past 90* w/ full supination and wrist extension. Hold for 60”.
  • pressure provocation test: Apply pressure to cubital tunnel for 30”.
  • scratch collapse test: Pt resists shoulder ER B, while therapist scratches in region of cubital tunnel. Potential allodynia results in symptomatic side “collapsing” w/ reflexive inhibition of ER.
  • specificity is .98 or higher for all of them
