Background: Asymmetry weight bearing is noted to be prevalent among individuals with neuro-musculoskeletal disorders affecting lower limbs loco-motor system.
Aim: To compare weight-bearing asymmetry (WBA) for patients with unilateral knee osteoarthritis (OA) with that of age and sex matched apparently healthy individuals and to investigate the associations between WBA and pain intensity (PI) and duration (Do) of knee OA.
Methods: Thirty consecutive patients aged 45 – 80 years with unilateral OA of the knee and 30 age and sex matched individuals (13 males and 17 females) were purposively recruited into the study as controls. Weight bearing through the lower limbs in standing was assessed using two juxtaposed bathroom weighing scales. The weight reading on each scale was read off and recorded to the nearest kg. Data were analyzed using descriptive and inferential statistics at p < 0.05.
Results: The OA group demonstrated greater WBA than the control group (t value 1.561,p-value 0.000*). There was no significant correlation between the WBA and PI (r = 0.12, p = 0.52) and WBA and Do of the knee OA (r = 0.32; p = 0.09) respectively.
Conclusions: Patients with knee OA demonstrated greaterWBA than the control group. There is no significant association between WBA and clinical measure of pain intensity and duration of knee OA. The results of this study suggest that Knee OA increases the degree of WBA.
