Title: Conservative Treatment for Hip Osteoarthritis: Effect of Manual Treatment and Hip School on Pain, Disability and Quality of Life - a Single-blinded Randomized Controlled Trial
Brief Summary: The purpose of the study is to evaluate the effect of manual treatment and a patient education programme for patients without indication for hip surgery.


Options:
A: Inclusion Criteria:

The OA condition will be assessed by physical examination based on the clinical criteria of the American College of Rheumatology criteria. The clinical criteria consisted of pain in the knee and any three of the following:

1. aged 50 years of age or over;
2. \<=30 minutes of morning stiffness;
3. crepitus on active joint motion;
4. bony tenderness;
5. bony enlargement; or
6. no palpable joint warmth.

This classification has been reported to yield 84% specificity and 89% sensitivity for diagnosis of OA knee.

Exclusion Criteria:

1. other connective tissue diseases affecting the knee;
2. knee joint steroid injections within the preceding three months;
3. having a hearing aid or pacemaker in situ (this is to avoid possible interaction between the pacemaker and the magnetic pellets);
4. receiving AT within the preceding three months;
5. suffering from aural injuries or infections; and
6. inability to understand instructions or give consent.

The assessment is conducted by a research assistant who will receive intensive coaching on the physical assessment and therapy administration by the research team. Potential subjects will be further assessed by a registered medical practitioner who has over 15 years of clinical experience when the assessment on the OA condition by the RA and the research team is in doubt.
B: Inclusion Criteria:

* Men or non-pregnant women
* Aged \>= 40
* Outpatient setting

* At least moderate pain on the WOMAC pain scale (\>3 on a standardized scale range from a minimum of 0 to a maximum of 10)
* Must understand German
* Informed Consent documented by participant signature

Exclusion Criteria

* Pregnant women
* Aged \< 40
* History of an inflammatory rheumatic disease
* Non-knee musculoskeletal pain as or more severe than the knee pain
* Glucocorticoid injections in the knees in the previous three month
* Previous osteotomy
* Unilateral hemiprosthesis
* Unilateral total joint replacement
* Being treated for cancer
* Participation in another clinical trial
C: Inclusion Criteria:

clinical criteria for the diagnosis of osteoarthritis of the hip (sensitivity 86% and specificity 75%) are:

* Medial hip rotation ≥15º, pain during medial rotation of the hip, morning fatigue in hip\> 60 minutes and older than 50 years or
* Medial hip rotation \<15, hip flexion ≤ 115

Exclusion Criteria:

* Previous surgery or hip replacement or knee joint
* Another surgery in the lower extremities performed within 6 months, rheumatoid arthritis
* Uncontrolled hypertension or risk (moderate - high) of cardiac complications during exercise
* Disability unrelated to the hip or knee to prevent the safe participation during exercise, appliance of manual therapy or during march: vision problems affecting mobility, body weight equal to or greater than 155 kg, primary neurogenic disorder or significantly limitation of the lumbar level,advanced osteoporosis with manual therapy or other treatment technique that may interfere with the study
* With inability to understand the instructions and complete the study assessments
D: Inclusion Criteria:

* patients referred from general practitioner, chiropractor or orthopaedic surgeon
* unilateral hip pain of minimum 3 months' duration
* radiology criteria for hip OA: joint space width (JSW) \< 2.0 mm or a side difference in JSW of \> 10%
* adequate mastering of the Danish language to complete instructions and questionnaires

Exclusion Criteria:

* inflammatory joint disease
* previous hip or knee alloplastic
* secondary arthritis due to hip fracture or infection
* bilateral hip pain
* hip dysplasia with a CE angle \> 25 degrees and an AA angle \> 10 degrees
* low back pain which dominates over the hip pain
* malignant disease
* patients with paresis or paralysis after neuromuscular, cerebrovascular or polyneuropathic disease
* hip pain resulting from labral tear, bursitis and/or snapping hip syndrome
* polyarthritis
* received manual treatment for the hip within the last year
