Group-based versus individual-based circuit training in elderly women with knee osteoarthritis: study protocol for a non-inferiority randomized controlled trial
Abstract
Background: Knee osteoarthritis (KOA) is one of the most prevalent health issues, affecting approximately 67% of women over 60 years old. Clinical guidelines recommend individualized muscle training to treat this condition. However, a lack of human and financial resources hinders the delivery of this treatment. In response to this limitation, group training may be an alternative. Although a few studies have compared group and individual exercise for knee OA, none have tested the non-inferiority of group-delivered circuit training specifically in elderly women. Therefore, this study aims to compare the non-inferiority of a group-delivered muscle training program to the same individually delivered training in clinical and functional aspects in elderly women with KOA.
Methods: This is a randomized controlled non-inferiority trial with two arms, parallel groups, blinded evaluator, conducted in Petrolina-PE, evaluating women aged 60 or older. Participants randomly assigned will undergo an 8-week training, either in individual sessions (control group-IB) or as part of a group (intervention group-GB) of four participants, supervised by a physical therapist. Blind assessments at baseline, immediately post-intervention, and 4 weeks post-intervention will include feasibility, safety, and satisfaction analysis of the training program; pain; quality of life; and physical function. Data will be analyzed using the Statistical Package for Social Sciences (SPSS) version 22. Estimated…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
