Title: A Pilot Study Testing a Hatha Yoga Exercise Program in Older Women With Knee Osteoarthritis
Brief Summary: The study hypothesized that it is feasible and safe to use Hatha yoga in older women with knee osteoarthritis (OA), and practicing Hatha yoga regularly will help reduce pain and stiffness, enhance physical function, and improve quality of sleep and quality of life in older women with knee OA.


Options:
A: 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
B: Inclusion Criteria:

* community-dwelling women aged 65 years or over
* had a symptomatic OA of knee diagnosis for at least 6 months
* had no previous training in any form of yoga; and
* were not currently participating in a supervised exercise program
* cognitively intact

Exclusion Criteria:

* symptoms of joint locking;
* instability indicated by chronic use of a knee brace, cane, walker, or wheelchair;
* a corticosteroid injection in the symptomatic joint within three months of study entry;
* a hyaluronic acid injection in the symptomatic joint within six months of study entry;
* a history of knee surgery within the last two years or a joint replacement at any point;
* individuals who had self-reported significant medical comorbidities that might preclude exercise participation such as: a) uncontrolled high blood pressure or existing heart condition; and b) other comorbid condition with overlapping symptoms (i.e. fibromyalgia, rheumatoid arthritis) were also be excluded.
C: Inclusion Criteria:

* Osteoarthritis of hip or knee according to the clinical criteria of the American College of Rheumatology

Exclusion Criteria:

* other pathology explaining the complaints;
* complaints in less than 10 out of 30 days;
* treatment for these complaints with exercise therapy in the preceding six months;
* under 50 or over 80 years of age;
* indication for hip or knee replacement within one year;
* contraindication for exercise therapy;
* inability to understand the Dutch language;
* a high level of physical function (since patients who perform at a high level of physical function at baseline do not need to increase their level of physical function. A high level of physical function was operationalized on a score of less than two on the sections walking ability and physical function of the Algofunctional index)
D: Inclusion Criteria:

* Symptomatic osteoarthritis of the hip(s) or knee(s) according to American College of Rheumatology (ACR) clinical and radiographic (hip) criteria.

Exclusion Criteria:

* Currently participating in recreational physical activity more than twice a week.
* Unable to walk indoors for more than 10 minutes without a walking aid.
* Unable to exercise at a moderate level due to major co-morbidity.
* Incontinent, afraid of water or uncontrolled epilepsy.
* Low back pain referring to limbs.
* Joint replacement surgery in past year.
* Arthroscopic surgery or intra-articular injections in knee or hip in past 3 months.
