Protocol summary

Study aim
Determining the effect of eight weeks of closed range of motion exercises in the water environment on pain, performance, in women with knee osteoarthritis.
Design
This study was a blind one-way clinical trial (the evaluator does not know who is in which group) with parallel groups with a pre-test-post-test design in which 32 patients with knee osteoarthritis with instability were studied in two groups. Phase 3 will be studied.
Settings and conduct
The place of conducting the evaluations and tests of the study will be the corrective movements and sports rehabilitation laboratory of the Faculty of Sports Sciences of Razi University.
Participants/Inclusion and exclusion criteria
- Age over 40 years. - Having the clinical criteria of knee osteoarthritis of the American College Rheumatology. Having a score of ≤II in the Kellgern and Lawrence criteria. -pain score of at least 4 on the visual analogue pain scale. - Reduction of joint space or osteophyte in radiography. Exclusion criteria: - uncontrolled diabetes, (BMI>40kg/m2), patients with extreme obesity. Physiotherapy or knee surgery (during the last 12 months).Lower limb arthroplasty. Intra-articular steroid injections (during the last 6 months).arthroplasty.
Intervention groups
Closed Kinetic Chain exercises In this study, the subjects are randomly allocated in water-based and land-based closed movement chain training intervention groups. The exercises will be performed for eight weeks, three sessions a week and 60 minutes each week.
Main outcome variables
Assessment of pain intensity by VAS visual scale; Performance (UGT test, 40 meter walking test and going up and down 8 standard stairs); Knee instability;

General information

Reason for update
In the system, there was an expected date of patient recruitment, but the actual date of the researchers' patient recruitment was different. So, it should be corrected.

Randomization (investigator's opinion)
Randomized
Randomization description
Subjects will be randomized based on the Random Number Generator software, and then based on the concealment of allocation by the SNOSE method, they will be divided into groups of water-based closed motion chain exercises (n=16) and land-based closed motion chain exercises (n=16). n) will be allocated. The random distribution list will be extracted from the software by a person not involved in data collection and will be provided to the laboratory expert. After evaluating each subject, by removing one of the sealed envelopes, the subject and the evaluator will be informed of the assigned group.
Blinding (investigator's opinion)
Single blinded
Blinding description
In this study, since the evaluator and the subjects will be informed about the intervention groups after the evaluation of the primary and secondary outcomes, the researcher will not have any information about the exercises and interventions assigned to the groups. However, it is not possible to blind the subjects from the study interventions. It will also be possible to inform the person who will analyze the data about the groups and exercises assigned to them.

Intervention groups

1

Description
Intervention group: Water-based Closed Kinetic Chain exercises: The exercises will be applied by an expert certified in the field of corrective exercises and sports rehabilitation. The exercises will also be approved by a physiotherapist specializing in exercise therapy. The exercises will be performed for eight weeks, three sessions a week, and 60 minutes each week. In each session, 10 minutes of warm-up exercises (forward walking, backward walking, lateral walking, and stretching movements), 10 minutes of cooling down exercises (stretching movements) and the main exercise will last 40 minutes. The temperature of the pool for water-based closed kinetic chain exercises will be 32 degrees in a shallow environment with dimensions of 152 x 86 cm and a depth of 95 cm. Tools such as chairs, steps, weights, stretch bands, pilates balls, etc. will also be used in the implementation of study training protocols. The main program of closed kinetic chain exercises includes exercises such as mini squats, front and side step-ups, front and side step-downs, wall sliding, heel rising, lunge exercises from the front and sides, quadriceps setting exercises, and single leg mini squats.
