  1. Evaluate the effect of an exercise therapy program and patient education, versus patient education only, on hip function among patients with radiologically verified hip OA
  2. To identify biomechanical differences during gait, one-leg standing , and two-legged-raise analysis in patients with hip OA following either exercise therapy and patient education program, or a patient education program only.

Main Hypothesis:

Significant improved hip function (WOMAC) will be demonstrated in patients with hip osteoarthritis (OA) (radiographically verified hip OA) following a patient education program and a 12 week exercise therapy program, compared to those only going through a patient education program.

Material and Methods:

110 patients with radiographically verified hip OA will be included in the randomized controlled trial; they will be randomized into:

  1. Patient Education, or
  2. Patient Education in addition to a supervised exercise program.

The main outcome is:

The Disease Specific WOMAC-Index.

Secondary outcome measures are:

SF-36v2 (quality of life),PASE (activity score), Self-efficacy for pain, muscle strength tests, gait analysis (biomechanical analysis),6 minutes walking test, Åstrand's bike test, range of motion.


The PhD student is accepted at the University of Oslo,and the study has so far included 17 subjects.

The study will be carried out:

NAR-Orthopedic Centre, Ullevaal University Hospital in collaboration with Diakonhjemmet Hospital and University of Delaware.

The study is included in our research program for active rehabilitation.

  Show Detailed Description


Ages Eligible for Study:   40 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Between 40 and 80 years old with uni- or bilateral hip disability
  • Harris Hip Score (36) between 60 and 95. Harris Hip score (0-100 points) is widely used as an assessment of hip function in patients with hip OA. Harris Hip Score of 60 or below are used regularly at our institution as one of the criteria for hip surgery (arthroplasty).
  • Patients will be included if they have more than 3 months of hip pain.
  • Patients with radiographic verified hip OA (Danielson's criteria for radiographic OA: Danielsson's criteria for minimal joint space: < 4 mm < 70 years, < 3 mm ≥ 70 years, or 1 mm difference between hips).

Exclusion Criteria:

  • Patients have a history of resent trauma or functional impairment to the lower limbs or diseases which might interfere with participation (rheumatoid arthritis, cancer, osteoporosis, severe back pain, knee OA).
  • Patients with co-morbidities not tolerating physical activities
