Introduction: Appropriate exercise therapies are still being investigated for primary knee osteoarthritis, which greatly contributes to chronic pain and functional impairment in older adults.
Objective: The purpose of this study was to evaluate the effectiveness of adding core stability to biofeedback-assisted quadriceps-hamstring strengthening for individuals with primary osteoarthritis of the knee.
Methodology: Participants between the ages of 50 and 65 participated in a parallel-group, randomised controlled study conducted at a single location. For six weeks, participants participated in twice-weekly supervised exercise sessions. The Western Ontario and McMaster Universities Osteoarthritis Index was used to assess functional status at baseline and on a weekly basis, while the Numeric Rating Scale was used to measure the intensity of pain.
Results: Forty participants were randomized, with 39 completing the study. Both groups shown gradual enhancements in pain and functionality. Significant between-group differences in pain emerged from week four, and by week six, the combined intervention group showed lower pain levels compared to the strengthening-only group. Functional outcomes also showed significant differences at week six, favoring the combined intervention. Statistical analysis revealed significant time-by-group interactions for both pain and functional measures.
Discussion: The addition of core stabilization appears to enhance the effectiveness of strengthening exercises, possibly by improving neuromuscular control and joint stability.
Conclusions: Incorporating core stabilization into strengthening programs provides additional short-term benefits in reducing pain and improving function in individuals with primary knee osteoarthritis.
