Effectiveness of Rhythmic Stabilization (PNF) vs. Conventional Physiotherapy in Knee Osteoarthritis

Abstract

Knee osteoarthritis (OA) is a degenerative condition marked by pain, stiffness, reduced range of motion (ROM), and impaired proprioceptive accuracy, negatively impacting quality of life. Proprioceptive Neuromuscular Facilitation (PNF) stretching, particularly rhythmic stabilization, has shown potential for addressing these issues by stimulating mechanoreceptors and improving flexibility and pain management.

This study compared the effectiveness of rhythmic stabilization PNF to conventional physiotherapy in managing Grade 2-3 knee OA. Thirty-six participants aged 40–60 were randomly assigned to Group A (rhythmic stabilization PNF) or Group B (conventional physiotherapy). Outcome measures included the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Visual Analog Scale (VAS).

Results showed significant improvements in pain reduction, flexibility, and functional mobility in both groups, with Group A achieving superior outcomes. Rhythmic stabilization PNF emerges as an effective therapeutic option for knee OA, offering enhanced patient outcomes and better quality of life.
