26
Q

Trochanteric bursitis clinical presentation

27
Q

trochanteric bursitis intervention

A
  • pt education on activity modification and positioning for relief
  • stretch tight structures causing postural deviations or asymmetries

A

RA

29
Q

A
  • pain anterior hip or thigh
  • aggravated by excessive hip flex
  • can be related to OA or iliopsoas muscle tightness
30
Q

Ischial bursitis clinical presentation

A

  • aggravated by stairs/incline walking (when hip is flexed and extensors are contracted)
  • avoidance of sitting on affected hip
31
Q

diagnostic test for bursitis

A
  • none
  • diagnosis made by clinical examination
32
Q

What two tests may be positive for ITB tightness

  • noble compression test
  • Ober’s test
33
Q

What does Craig’s test measure

A
  • femoral anteversion and retroversion
34
Q

Different angles of piriformis

A
  • ER of hip at < 60 degrees hip flex
  • IR of hip at > 90 degrees hip flex
35
Q

tightness, straining, or spasm of the piriformis can result in

A

compression of sciatic nerve and/or sacroiliac dysfunction

36
Q

signs and symptoms of piriformis syndrome
