SAM Ultrasound Device and Diclofenac PatchSustained Acoustic Device with 2.5% Diclofenac PatchPatients receive treatment from the wired SAM Ultrasonic Diathermy Device for 4 hours at least 5 days a week for 8 weeks combined with 2.5% diclofenac patch. The SAM device emits continuous ultrasound at 3 megahertz (MHz) frequency and 0.132 watts/cm2 intensity.

Primary Outcome Measures
NameTimeMethod
Change in Pain Units on a Scale (0-10) 0 Being Least, 10 Being Worst Pain From BaselineThrough study completion, average of 8 weeks

Change in the self described pain units on a scale by patient at baseline and post-

Change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)Time Frame: Through study completion, average of 8 weeks

WOMAC questionnaire will be utilized (Western Ontario and McMaster Universities Arthritis Index) at baseline and post-treatment to calculate the change in scores. WOMAC was divided into 3 categories: pain, stiffness, function and total score. The pain category consists of five scores from 0 - 4, 0 being no pain 4 is worst pain possible, for a range of 0 - 20 points. The stiffness category consists of two scores from 0 - 4, 0 being no stiffness 10 is worst stiffness possible for a range of 0 - 8 points. The function score consists of 17 scores from 0 - 4, 0 being normal function and 10 is severely limited function, for a range of 0 - 68 points. Total score is the sum of pain, stiffness, and function scores (range of 0 - 96).

Secondary Outcome Measures
NameTimeMethod
Change in Global Rating of Change (GROC) on a Scale (-7 to +7)Through study completion, average of 24 weeks.

Subject-reported change in overall pain on a scale, -7 = worst, +7 = best.

Change in the Pain & Sleep Questionnaire (PSQ-3)Through study completion, average of 24 weeks.

Subject-reported rating of impact of pain on sleep on a scale from 0 no impact, to 100 greatest impact

Change in Depression Anxiety Stress Scale (DASS21)Through study completion, average of 24 weeks.

Subject-reported measures of depression, anxiety, and stress on a scale of 0-3, 0 being not applicable, 1 meaning applicable to some degree, 2 meaning applicable often, and 3 meaning applicable most of the time. Questions are divided into three categories: depression, anxiety, and stress.
