Summary
Self-reported function and age significantly predict physical function in knee osteoarthritis patients. These factors explain a notable portion of the variance in mobility tests like stair climbing and TUG.
Area of Science:
- Orthopedics
- Gerontology
- Rehabilitation Medicine
Background:
- Knee osteoarthritis (OA) causes disability through complex physiological and functional interactions.
- Understanding these relationships is crucial for effective OA management and patient care.
Purpose of the Study:
- To investigate the associations between pain, body mass index (BMI), balance, self-reported function, and physical function.
- To explore these relationships in patients with unilateral and bilateral knee OA.
Main Methods:
- Fifty-two knee OA patients (mean age 59.0 years) were assessed.
- Measures included pain intensity, Lequesne Index (self-reported function), functional reach test (balance), stair climbing, and timed up-and-go (TUG) tests (physical function).
- Univariate and multivariate analyses were employed to explore associations.
Main Results:
- Significant positive correlations were found between physical function and self-reported function, and between physical function and age in bilateral knee OA.
- Age was inversely correlated with balance in unilateral knee OA.
- Self-reported function and age explained 27.0% and 29.0% of the variance in stair climbing and TUG tests, respectively.
Conclusions:
- Self-reported function and age are significant predictors of physical function in individuals with knee OA.
- These findings highlight the importance of considering patient-reported outcomes and age in assessing and managing physical function in knee OA.
