The aim of this study was to investigate the effectiveness of adding hip device-assisted concentric abductor strengthening (HDACAS) program to knee device-assisted concentric flexor-extensor strengthening (KDACFES) program on pain, function, physical performance, quality of life and gait parameters in patients with knee osteoarthritis (OA).
This prospective randomized single-blind controlled study was conducted at Kütahya Health Sciences University (KHSU) Evliya Çelebi Education and Research Hospital (ECERH) Physical Medicine and Rehabilitation (PMR) annex building between September 2023 and March 2024. The study protocol was approved by the ethics committee of the same university (2023-03/03).

| Western Ontario and McMaster Universities (WOMAC) | Assessments consist of three components: pain, stiffness, and functionality. The WOMAC consists of three subscales: pain (five questions), stiffness (two questions), and physical function (17 questions). The subscale scores can vary, with pain ranging from 0 to 20 points; stiffness, 0 to 8 points; and physical function, 0 to 68 points. Scores range from 0 to 96 for the total WOMAC where 0 represents the best health status and 96 the worst possible status. The higher the score, the poorer the function. | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| The Lequesne Algofunctional index | It is a disease-specific measure used to assess the pain, maximum walking distance, and daily life activities of knee osteoarthritis patients. The Lequesne Algofunctional index has an interview format questionnaire, including 10 questions divided into three sections regarding pain, maximum distance walked and activities of daily living. The score ranges from 0 (no pain, no disability) to 24 (maximum pain and disability. | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| TIME UP AND GO TEST | With this test, patients' ability to maintain balance during transfer and walking is assessed. One source suggests that scores of ten seconds or less indicate normal mobility, 11-20 seconds are within normal limits for frail elderly and disabled patients, and greater than 20 seconds means the person needs assistance outside and indicates further examination and intervention. | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| 30 SECOND CHAIR TEST | This test requires the individual to sit and stand continuously for 30 seconds with arms crossed over the chest and is based on the maximum number of repetitions the individual can perform. The 30-second chair stand involves recording the number of stands a person can complete in 30 seconds rather then the amount of time it takes to complete a pre-determined number of repetitions.Great: 19 or more reps in 30 seconds means your endurance and lower-body strength are above average. You have the greatest life expectancy. Average: Between 10 and 18 reps indicates average endurance and lower-body strength. Poor: 9 reps or fewer should be considered a warning sign. |
| Measure | Description | Time Frame |
|---|---|---|
| Visual Analog Scale (VAS) | The intensity of pain ranges from '0' to '10', with '0' indicating no pain and '10' representing the worst pain the person has ever experienced in their life | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| Mini Osteoarthritis Knee and Hip Quality of Life Scale |

Before and after the treatment, all patients were evaluated by a blind evaluator in terms of physical examination, pain and functionality, physical performance, quality of life and gait parameters.
| knee device-assisted concentric flexor-extensor strengthening (KDACFES) | Device | All participants received device-assisted strengthening exercises with increasing doses according to a pre-determined strengthening program for a total of 6 weeks, 4 days a week, and a total of 24 sessions |

| TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| 40 METER SELF PACED WALK TEST | It is a test focused on measuring mobility and function. It is based on walking a certain distance in the fastest possible time, competing against time. A fast-paced walking test that is timed over 4 x 10m (33 ft) for a total 40 m (132 ft) (2). As a direct measure of the ability to walk quickly over short distances, which is an activity that is important but often limited in people with hip and/or knee OA. Regular walking aid is allowed and recorded. Time of one trial, with turn time excluded, is recorded and expressed as speed m/s by dividing distance (40 m) by time (s) | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| SIX MINUTES WALK TEST | The 6-minute walk test, which is a reliable and valid mobility test for measuring walking activity, is the most commonly used test in clinical trials. The maximum distance that can be walked over a 6-min interval is recorded. Rest periods are allowed but included in the time Standardized encouragement (e.g., keep going you are doing really well") can be given at minute intervals. Regular walking aid is allowed. Practice test not needed in most clinical settings but if performed then at least 1 h rest should be allowed before the second test. The greatest distance is then recorded | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
| STAIR CLIMB TEST | It is a test that varies in the number of steps, but the most commonly used and the version found on the OARSI website is the 9-step stair climb test. Ascend and descend flight of nine stairs in a usual manner, and at a safe and comfortable pace. Use of any walking aid and handrail is permitted and recorded. Total time to ascend and descend steps for one trial is recorded in seconds | TIME FRAME 1: pre-intervention (up to 72 hours), TIME FRAME 2: post-intervention(up to 72 hours) |
It is derived from the original Osteoarthritis Knee and Hip Quality of Life (OAKHQoL) questionnaire, developed to assess Health-Related Quality of Life (HRQoL) in patients with knee and/or hip osteoarthritis. It includes five subscales: physical activities, mental health, pain, social support, social functioning; with three additional independent items addressing sexual life, professional life, and fear of being dependent. The numerical rating scales in the items range from 0 (worst) to 10 (best). Scores were obtained by computing the means of the item scores in each subscale. The last three items' score (independent items) becomes the corresponding score. |
