The Effects of 24 Weeks Sensorimotor Training on Balance, Physical Function, and Pain in Women with Knee Osteoarthritis

Background: Osteoarthritis (OA) is a common degenerative joint disease that often leads to impaired postural control, pain, and reduced physical function. Exercise is considered a first-line treatment, with sensorimotor training being an effective approach for managing OA. However, the optimal method of sensorimotor training for individuals with OA has not yet been established. Thus, the aim of this study was to compare the effects of a 24-week Gyrokinesis method (GK) versus Pilates (PL) intervention on balance control, function, pain and kinesiophobia in women with knee OA. Methods: Twenty women (aged 60 ± 7 years) with grade 2 or 3 knee OA were assigned to either GK (n = 12) or PL (n = 8). Both groups trained twice weekly for 24 weeks. Pre- and post-intervention assessments included postural sway parameters (RMS, velocity, frequency), physical function tests (e.g., TUG, Sit-to-Stand), flexibility, pain (Brief Pain Inventory), kinesiophobia (Tampa Scale), and quality of life (SF-36). Results: GK resulted in significantly greater improvements than PL in postural sway mean velocity AP right (GK -53.85% vs. PL -20.17%), AP left (GK -43.48% vs. PL +13.45%), and ML left (GK -40.18% vs. PL +37.95), pain reduction (GK -82.5% vs. PL -33.3%), and physical function (Sit-to-Stand: GK +75.9% vs. PL +3.7%; TUG: GK -16.4% vs. PL -13.8%; Step Test right: GK +34.2% vs. PL +19.9%; Step Test left: GK +41.4% vs. PL +18.1%) (all, p < 0.05). No significant between-group differences were observed for kinesiophobia or SF-36 scores (both, p > 0.05). Conclusions: Gyrokinesis method may be more effective than Pilates in enhancing balance, reducing pain, and improving physical function in women with knee OA. These findings support the use of the Gyrokinesis method in rehabilitation programs for individuals with OA.
