Background Foot and ankle joints are commonly affected by osteoarthritis. Pain, stiffness, swelling, limited range of motion and difficulty walking are problems.
Objectives The aim of this study was to investigate whether there was a relationship between clinical hindfoot measurements, arch flexibilty and intensity of pain parameters in patients with osteoarthritis (OA) who complained of foot pain.
Methods 27 patients with OA participated in this study. The mean age was 53,06±8,5 years. All subjects were right-handed. Navicular height, static heel-calf angles of both feet was measured in weightbearing (wb) and non-weightbearing (nwb) positions. Also subtalar joint (STJ) inversion and eversion range of motion were measured with universal goniometer. The pain intensity of the subjects at rest, at the morning and at the end of the day (evening) were questioned with the Visuel Analog Scale (VAS). Relationships between variables were investigated using Pearson's correlation analysis.
Results The resulting data of min-max, average, and standard deviation values are shown in the table.
The navicular drop values of these patients which shows flexibility of the foot were found to be as normal as previously mentioned in the literature (6.9±3.4mm) (p>0,05). The correlation was found between end of the day VAS scores and left foot navicular drop values (p<0.05). There was negative correlation between right heel-calf angle (R-HL) and right navicular height in non-weight bearing position (nwb), right heel-calf angle and left navicular height in weight bearing position, left heel-calf angle and left navicular height in weight bearing position (p<0.05). There was positive correlation between weight bearing and non weight bearing heel-calf angle, right heel-calf angle (wb) and right navicular height (nwb), left and right heel-calf angles in weight bearing positions (p<0.05).
Conclusions The correlation found between navicular height measurement and calf-heel angles implied that there is a relationship among clinical measurements used for biomechanical analysis of the hind foot in patients with osteoarthritis and foot pain. Also foot flexibility is similar to healthy people in early stages of Osteoarthritis.
