Objective: To investigate the impact of unilateral knee osteoarthritis on static and dynamic postural control during gait initiation in elderly individuals, comparing them to active, healthy older adults. Methodology: Forty elderly individuals were divided into two groups: G1, composed of 20 individuals with unilateral knee osteoarthritis awaiting total knee arthroplasty (TKA), and G2, composed of 20 active elderly individuals without osteoarthritis. Biomechanical assessments were conducted using a plantar pressure platform to measure variables related to the Center of Pressure (COP) during bipedal postural control with eyes open and closed, and gait initiation. The variables analyzed included COP displacement amplitude in the anteroposterior (COPAP) and mediolateral (COPML) directions, and mean COP displacement velocity in the anteroposteri.. Read More»
