Descrizione
Inclusion Criteria:
- 40 years of age or older
- Meet the American College of Rheumatology (ACR) clinical criteria for a diagnosis of knee OA. The ACR clinical criteria for knee OA includes knee pain plus 3 of the following 6 criteria:
- age > 50 years,
- morning stiffness of < 30 minutes,
- crepitus on active movement,
- tenderness of the bony margins of the joint,
- bony enlargement of the joint noted on exam,
- lack of palpable warmth of the synovium. Based on this criteria, a subject who is less than 50 years but has knee pain and 3 of the other 5 criteria would also be classified as having knee OA.
Exclusion Criteria:
- do not meet the ACR clinical criteria for knee OA,
- are scheduled for total knee arthroplasty (TKA) surgery,
- have undergone TJA surgery on any lower extremity joint,
- exhibit uncontrolled hypertension (i.e. individuals not currently taking medication for hypertension whose systolic blood pressure is greater than 140 mm Hg or diastolic blood pressure greater than 90 mm Hg at rest),
- have complaints of low back pain or other lower extremity joint pain that affects function at the time of recruitment,
- have a history of neurological disorders that would affect lower extremity function (stroke, peripheral neuropathy, parkinson's disease, multiple sclerosis, etc.),
- are women who are pregnant.

|---|---|
|
Comparatore attivo: exercise
Subjects in this arm receive 12 exercise sessions in 9 weeks.
|
The program starts with a 10 minute aerobic exercise warm-up (treadmill walking or stationary cycling).
Subjects then perform a series of strengthening, stretching, and neuromuscular control activities which are core exercises for the program and mandatory.
In addition to the above core exercises, therapists have the option to select additional optional exercise activities, based on the initial examination findings.
These exercises will address strength or flexibility in the hip, and ankle if impairments are identified in the initial examination.
|
|
Comparatore attivo: exercise + manual therapy
Subjects in this group receive exercise combined with manual therapy techniques for 12 sessions in 9 weeks.
|
The program starts with a 10 minute aerobic exercise warm-up (treadmill walking or stationary cycling).
Subjects then perform a series of strengthening, stretching, and neuromuscular control activities which are core exercises for the program and mandatory.
In addition to the above core exercises, therapists have the option to select additional optional exercise activities, based on the initial examination findings.
These exercises will address strength or flexibility in the hip, and ankle if impairments are identified in the initial examination.
The manual therapy (MT)techniques are maneuvers that are applied with manual force from the treating therapist.
The MT techniques will include a series of accessory motion techniques, manual stretching , and soft tissue manipulation (deep massage to muscles and connective tissues associated with knee function).
Core techniques include anterior-posterior and posterior-anterior tibiofemoral translations, superior-inferior and medial-lateral patellofemoral mobilizations, knee flexion and extension mobilizations that may be combined with varus-valgus stresses,medial-lateral tibial rotations, manual stretching of the quadriceps, rectus femoris, hamstring, and gastrocnemius muscles, and soft tissue manipulations of the quadriceps, peri-patellar tissues, hamstring, hip adductors, and gastroc-soleus muscle groups.
There are optional MT techniques for the hip, and foot and ankle joints that can be selected by the therapist based on initial examination findings.
|
|
Sperimentale: exercise + booster
subjects in this arm will receive exercise sessions delivered with booster sessions (8 sessions in the first 9 weeks, 2 sessions at 5 months, 1 session at 8 months, and 1 session at 11 months).
|
The program starts with a 10 minute aerobic exercise warm-up (treadmill walking or stationary cycling).
Subjects then perform a series of strengthening, stretching, and neuromuscular control activities which are core exercises for the program and mandatory.
In addition to the above core exercises, therapists have the option to select additional optional exercise activities, based on the initial examination findings.

Cost/Utility Ratio
Lasso di tempo: 2 years
|
In the analysis, the effectiveness term will be quality adjusted life years, which is the product of the quality of life utility associated with a health state and the length of time lived in that state, summed over time.
Utilities are a measure of preference for a health state and range from 0 (death) to 1 (perfect health).
In this analysis, utilities will be derived from EQ-5D scores.
The cost-effectiveness ratio (or, in this analysis, the cost-utility ratio) is the difference in cost divided by the difference in quality-adjusted life-years between intervention groups.

Change in Numeric Knee Pain Rating Scale
Lasso di tempo: Change from Baseline to 9 weeks, 1 and 2 years
|
Subjects will rate their worst knee pain in the last 24 hours using an 11 point numeric pain rating scale with 0 representing "no pain" and 10 representing " the worst pain imaginable."
|
Change from Baseline to 9 weeks, 1 and 2 years
|
|
Global Rating of Change
Lasso di tempo: Change from baseline to 9 weeks, 1 and 2 years
|
The global rating of change is a 15 item scale in which subjects will rate the degree to which their knee condition has changed from the time treatment was initiated to the present.24
The subject responds to the following query: "Please rate your overall knee's condition from the time you began treatment until now (check only one)."
The items range from "A very great deal better" to "A very great deal worse."

|
Change in EQ-5D
Lasso di tempo: Change from Baseline to 1 and 2 years
|
The EQ-5D is a generic health-related quality of life measure.
The EQ-5D consists of the following five dimensions: 1) Mobility, 2) Self-care, 3) Usual activities, 4) Pain/discomfort, and 5) Anxiety/depression (AD).Each dimension has three possible levels (i.e., 1, 2, or 3), representing "no problems," "some problems," and "extreme problems," respectively.
Respondents are asked to choose one level that reflects their "own health state today" for each of the five dimensions.
