Effects Of Severity Of Osteoarthritis On The Temporospatial Gait Parameters In Patients With Knee Osteoarthritis

Objective: The aim of this study was to investigate the differences in temporospatial parameters in according to severity of knee osteoarthritis (OA). Methods: The study included a total of 110 subjects with no orthopedic or neurologic disease that might affect gait were divided into three study and one control groups. Eighty subjects (mean age: 53.13 +/- 6.78 years) were diagnosed with bilateral knee OA and divided into groups according to Kellgren-Lawrence radiologic scale: the Phase 1 group included 29 subjects, Phase 2, 28 subjects, and Phase 3, 23 subjects. The control group was composed of 30 healthy subjects (25 females, 5 males; mean age: 41.50 +/- 5.79 years). Temporospatial gait data were evaluated using a gait analysis system. Methods: There were no significant differences in all temporospatial parameters between the control group and the Phase 1 and 2 OA groups (p>0.05). There was a significant decrease in cadence, gait velocity, stride length and step length (p<0.008) and a significant increase in stride time, double support time, step time, single support time and stance phase length in patients with Phase 3 knee OA compared to the other groups (p
