Arm && Interventions

Group	Intervention	Description
Swedish Massage	Massage Therapy	Swedish massage for one hour, once per week, for eight weeks. At week 10, 50% of patients will be randomized to a maintenance dose (one hour of Swedish massage every two weeks), and 50% will be randomized to Usual Care.
Light Touch Bodywork	Massage Therapy	Light-touch bodywork for one hour, once per week, for eight weeks. At week 10, 50% of the patients will be randomized to a maintenance dose (one hour of light-touch massage every two weeks, and 50% will be randomized to Usual Care.
Usual Care	Massage Therapy	Those initially randomized to the usual care control will be rolled into the Swedish massage intervention (one hour of Swedish massage, once/week for eight weeks) at week 25. At week 34, 50% of patients will be randomized to a maintenance dose (one hour of Swedish massage every two weeks), while 50% will be randomized back to Usual Care.

Primary Outcome Measures

Name	Time	Method
Change in Western Ontario and McMaster Universities Osteoarthritis of the Knee and Hip Index (WOMAC)	Baseline, 8, 16, 24, 36 and 52 weeks (Baseline, 8, 16, 24, 32, 40 and 48 for Usual Care group)	The Index is self-administered and assesses the three dimensions of pain, disability and joint stiffness in knee and hip osteoarthritis through 24 questions. WOMAC 3.1 is available in 65 languages using either a five-point Likert scale or a 100 mm visual analog scale. The WOMAC has been subject to numerous validation studies to assess reliability and responsiveness to change in therapy, including physical forms of therapy

Secondary Outcome Measures

Name	Time	Method
Change in Pain: The Visual Analog Scale (VAS)	Baseline, 8, 16, 24, 36 and 52 weeks (Baseline, 8, 16, 24, 32, 40 and 48 for Usual Care group)	Used to measure pain sensation intensity evoked by nociceptive stimuli. Subjects quickly and easily rate stimuli within the series by indicating level of pain on a 100 mm scale. Pain intensity is represented by the participant drawing a line on the scale indicative of pain experienced (0 = no pain, to 100 = worse pain imaginable). The VAS is anchored at the left by "no pain sensation" and at the right by "the most intense pain sensation imaginable."
Change in Pain: PROMIS Pain Interference Questionnaire	Baseline, 8, 16, 24, 36 and 52 weeks (Baseline, 8, 16, 24, 32, 40 and 48 for Usual Care group)	Patient Reported Outcomes Measurement Information System (PROMIS), funded by the National Institutes of Health (NIH), is a system of highly reliable, valid, flexible, precise, and responsive assessment tools that measure patient-reported health status. The Pain Interference Questionnaire has 6 questions answered on an ordinal scale of five gradations.
Change in Joint Flexibility	Baseline, 8, 16, 24, 36 and 52 weeks (Baseline, 8, 16, 24, 32, 40 and 48 for Usual Care group)	Joint flexibility is defined as the range of motion (ROM) allowed at the knee. The knee's ROM is measured by the number of degrees from the starting position of a segment to its position at the end of its full range of the movement. This is measured using a double-armed goniometer. A stationary arm holding a protractor is placed parallel with a stationary body segment and a movable arm moves along a moveable body segment. The pin (axis of goniometer) is placed over the joint.
Change in Physical Function	Baseline, 8, 16, 24, 36 and 52 weeks (Baseline, 8, 16, 24, 32, 40 and 48 for Usual Care group)	Measured time in seconds to walk fifty (50) feet (15 m) on a level surface within the clinic facilities.
