Title: Can Computer-based Telephone Counseling Improve Long-term Adherence to Strength Training in Elders With Knee Osteoarthritis (OA)?
Brief Summary: The purpose of this research is to determine whether computer-based telephone counseling will improve adherence to strength training in a population of elders with knee osteoarthritis.


Options:
A: Inclusion Criteria:

* a diagnosis of primary OA of the knee according to the ACR criteria, including radiologic evidence of OA
* age \>40 years
* symptomatic disease for at least 6 months prior to enrollment
* persistent pain despite receiving the maximum tolerated doses of conventional medical therapy, including acetaminophen (4 gm/day) and/or a nonsteroidal antiinflammatory drug (NSAID), with persistent pain defined as a minimum mean score of 25 mm on the visual analog scales (VAS) for global pain (0-100-mm range for each) daily pain during the month prior to study enrollment
* ability to attend followup appointments

Exclusion Criteria:

* secondary causes of OA
* local or systemic infection
* diabetes mellitus
* systemic arthritis
* allergy to anesthetic agent or contrast material
* coagulopathy
* anticoagulant therapy
* had previous IA steroid injection
* avascular necrosis of bone
* patients who are on specific OA pharmacological therapy (NSAIDS, opioids) for more than 2 weeks prior enrollment
B: Inclusion Criteria:

* osteoarthritis of the knee (ICD-9 Code of 715.16, 715.09 or 715.9)
* lives within interstate 95
* age 55 or older
* English speaking

Exclusion Criteria:

* Stroke or heart attack in last 3 months
* Treatment for cancer
* Severe systemic disease
* Medical condition that limits physical activity
* Inflammatory arthritis
* Plans for knee replacement
* Dementia or inability to follow exercise instructions and TLC system
C: 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.
D: Inclusion Criteria:

* English speaking adults (\>18 years of age)
* Provided with a diagnosis of knee OA by a physician
* Self-report of having experienced pain and disability related to knee OA for at least 6 months.

Exclusion Criteria:

* Skin conditions in which application of phototherapy may be contra-indicated (skin cancer, people receiving radiation therapy)
* History of total joint arthroplasty of the affected knee
* Red flags suggestive of non-musculoskeletal etiology (i.e. fever/chills, unrelenting night pain, multi-segmental or bilateral loss of sensation, sudden unexplained weight loss).
