About this trial

This is an interventional treatment trial for Patellofemoral Pain Syndrome

Eligibility Criteria

19 Years - 50 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patellofemoral pain syndrome ( Bilateral or unilateral)
  • Special tests: crepitus during compression test, patellar grind test (Clarke's sign), pain during compression test, palpation ( at least 2 )
  • Below 50 years old
  • Pain :after long sitting, up/down stair, squat, kneeling, running & jumping ( at least 2 )
  • Pain duration at least 1 month
  • At least 1 item of PSS score more than 3 cm

Exclusion Criteria:

  • Knee operation
  • Central or peripheral neurological deficits
  • Obvious knee joint or lower extremity malalignment
  • People involved in competitive sports
  • PSS sub-scale pain experienced last week more than 8cm

Arm Label

Leg Press

Hip Exercise

Control

Arm Description

Leg Press exercise for 3 times/week and sustain for 8 weeks.

Additional hip abductor and hip external rotator strength training to leg press exercise for people in this group. All participants received exercise for 3 times per week for 8 weeks.

Education was given during 8 weeks of study period. After 8 weeks of study, exercise was given as compensation.

Outcomes

Primary Outcome Measures

Muscle Strength by hand-held dynamometry, hip joint kinematics during step down by electromagnetic motion tracking system (FASTRAK, Polhemus ), pain severity by PFPS pain severity scale (PSS), functional performance by Anterior Knee Pain Scale(AKP).

5. Study Description

Brief Summary
The first purpose was to compare the difference between leg press exercise(LPE) and additional hip abductor and external rotator muscle strength training to leg press exercise(LPE+HAE) in muscle strength, hip kinematics during step down, pain severity and function for patients diagnosed with patellofemoral pain syndrome. The second one was to discover the relationship between the change in muscle strength performance and the difference of hip joint kinematics post treatment.
