One hundred participants with Grade 2-4 knee osteoarthritis and both genders were involved.
Participants were randomized into five groups: Group I (
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.
Statistically significant differences (
Prolonged applications of continuous ultrasound combined with exercises are effective in providing pain, mobility, functionality and activity in subjects with knee osteoarthritis.
