The objective of this study was to observe the immediate effect of a knee brace with a patellar hole versus without a patellar hole on pain perception in patients with knee osteoarthritis. To accomplish this, a double-blind, randomized controlled trial enrolled 108 patients divided into two groups (knee brace with a patellar hole or without a patellar hole). Patients were evaluated by the Visual Analogue Scale (VAS) in order to measure their pain sensation, the Timed Up and Go (TUG) test was used to evaluate their ability to walk, and the 8-m walking test (8MWT) was used to estimate their walking speed. Both groups presented significant reduction in pain perception, higher function of the lower extremities, and greater mobility while wearing a knee brace. However, the patients who wore a knee brace without a patellar hole presented more favorable results than those who wore a knee brace with a patellar hole: a 1.6-point reduction was found versus 1.1 points in the VAS, the patients presented 0.7 s less time versus 0.4 s in the TUG, and the speed was reduced by 1.4 s versus 0.8 s in the 8MWT. Therefore, the knee brace without a patellar hole presented more favorable results when compared with the knee brace with a patellar hole.

Objectives: To compare the effects of continuous and pulsed therapeutic ultrasound combined with strengthening exercises. Design: This is a double-blind randomized controlled trial. Setting: Pontifical Catholic University. Subjects: One hundred participants with Grade 2–4 knee osteoarthritis and both genders were involved. Intervention: Participants were randomized into five groups: Group I ( n = 20; in the first month, continuous ultrasound was applied), Group II ( n = 20; in the first month, pulsed ultrasound was applied), Group III ( n = 20; in the first and second months, continuous ultrasound was applied), Group IV ( n = 20; in the first and second months, pulsed ultrasound was applied) and Group V ( n = 20; patients received only exercise sessions for eight weeks). All patients in the groups that received ultrasound application performed exercises in the second month of treatment. The sessions occurred three times a week. Main measures: Pain was assessed using the visual analogical scale, functionality was assessed using the Lequesne questionnaire, range of motion was assessed using a universal goniometer, muscular strength was assessed using a dynamometer, mobility was assessed using the Timed Up and Go test and 8-meter walk test and the activity level was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Results: Statistically significant differences ( P < 0.05) were presented by Group III in the variables pain during activities of daily living (ADLs) 5.89 (2.18), mobility assessed by 8-meter test 2.68 (2.56), in pain 10.65 (4.40), function 25.50 (10.87) and total 38.65 (15.29) of WOMAC and functionality 9.10 (5.15). Conclusion: Prolonged applications of continuous ultrasound combined with exercises are effective in providing pain, mobility, functionality and activity in subjects with knee osteoarthritis.
