Title: Internet Arthritis Self-Management Study
Brief Summary: Individuals with with arthritic conditions (rheumatoid arthritis, osteoarthritis, or fibromyalgia) and internet and email access were randomized to receive an internet-based arthritis self-management program (treatment group) or to continue with usual care (control group). Questionnaires measuring health indicators, health behaviors, self efficacy and health care utilization were administered at baseline, six months and one year after the course. It was hypothesized that those participating in the course would have better outcomes than the control group at six months and one year.


Options:
A: Inclusion criteria:

* History of pain on most days (i.e., 4 or more days in a week) in one or both knees for at least 4 months during the year prior to study entry
* Duration of symptoms (defined as pain on most days for at least 4 months in 1 year) of less than 5 years
* Radiographic evidence of grade II knee OA
* Some level of disability, represented as a score of 3 or higher for at least three of the following WOMAC Index items: descending or ascending stairs; walking; bending; and performing daily activities

Exclusion criteria:

* Any uncontrolled medical condition that could prevent safe participation in the study (e.g., uncontrolled heart disease, blood pressure, or respiratory conditions)
* Any neurological condition that could affect coordination
* Inflammatory arthritis (e.g., rheumatoid or psoriatic arthritis)
* Participates in aerobic activity or resistance training for more than 60 minutes per week

* History of a knee corticosteroid injection in the 3 months prior to study entry
* Plans to move from the local area
* Plans to become pregnant during the study
B: 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
C: Inclusion Criteria:

* Clinical diagnosis of osteoarthritis

Exclusion Criteria:

* Must be able to speak and understand swedish
D: Inclusion Criteria:
