Objectives: Osteoarthritis of the knee is the most common form of arthritis and one of the causes of pain and physical disability. The aggregated locomotor function (ALF) score, a simple measure of observed locomotor function, using timed walking, stairs and transfers. The purpose of this study was to examine the relation between pain and physical diasability in patients with osteoarthritis of the knee.

Methods: One hundred twenty-six patients with bilateral knee osteoarthritis (107 female, 19 male) with a mean age of 55,51±6,79 years included to the study. The pain level was evaluated with a Visual Analogue Scale (VAS) in rest, activity and night. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and ALF score were used to assess physical function. The ALF score is a sum of the mean time (seconds) taken to complete three physical function tasks: walking eight meters, ascending and descending sevenstairs, and transferring from a sitting to standing position. Each task was carried out separately with a break in between. The sum score was added up for all tasks. Intercorrelations between parameters were computed through the Pearson's correlation analysis. A correlation coefficient between 0.26 and 0.49 reflects poor agreement, those between 0.50 and 0.69 reflect moderate agreement, and those 0.70 reflects high agreement.

Results: The mean body mass index and disease duration was found 31.5±4.9 kg/m2 53.2±57.9 months respectively. Significant relationships were found between pain and WOMAC (r= 0.65, p=0.0001) and walking time (r=0.37, p=0.0001), and transfers time (r=0.25, p=0.004), and stair ascent and descent time (r=0.36, p=0.0001) and stair descent time (r=0.32,p=0.0001). There was no significant relationships between pain and stair ascent time (r=-0.008, p=0.93).

Conclusions: In our study we determined that, pain was positively correlated with levels of all physical functions in patients with osteoarthritis of the knee, except levels of function in climbing stairs.
