Objectives: The functional performance and perception of function of the lower limbs and general function is considered of great importance in the management of patients with knee Osteoarthritis (OA). The purpose of this study was to determine the how PA level, sedentary life, and clinical presentation predict functional performance in patients diagnosed with knee OA.
Design: The participants for this study were individuals with OA of the knee recruited using stratified simple random sampling technique to recruit 98 the participants. The study centre was National Orthopaedic Hospital, Dala, Kano, Nigeria. The participants’ pain, physical activity level and clinical presentations were assessed using Visual analogue scale (VAS), International PA questionnaire (IPAQ), and knee OA outcome survey (KOOS) respectively. The functional performance of the participants was assessed using Timed up and go test (TUG), Stair climbing test (SCT) and Six minute walk test (6MWT).
Results: There were statistically significant correlations between TUG and VAS (r=0.220, p=0.029), GRC (r=-0.298, p=0.003), KOOS (r=0.261, p=0.009) and PA (r=-0.305, p=0.002). Also, there were significant correlations between Stair Climbing Time and VAS (r=0.332, p= 0.001), GRC (r=-0.342, p=0.001), KOOS (r=0.301, p=0.003) and PA (r=-0.321, p=0.001). Significant correlations were seen between 6MWT and VAS (r=-0.401, p=0.000), GRC (r=0.444, p=0.000), KOOS (r=-0.505, p=0.000) and PA (r=0.406, p=0.000). Predictors of each of the functional performance tests were TUG (GRC, KOOS & PA), SCT (GRC, KOOS, & PA) and 6MWT (VAS, GRC, KOOS & PA).
Conclusions: There were relationships between functional performance of the participants and clinical variables and the predictors of functional performance of knee OA patients were pain, physical activity level, KOOS and GRS.
