Knee osteoarthritis (OA) is one of the most widespread orthopedic disease that affects the elderly. The present study aims to evaluate the biomechanical effects of bilateral osteoarthritis on elderly patients compared to a control group using stabilometry parameters. The used parameters were center of pressure (CoP) 95% confidence ellipse area, CoP path length and maximum path velocity, CoP range...
The present study aims to determine the effect of professional sailing on the balancing ability compared to a control group using ultrasound-based provocation tests on a moving platform. The balancing capacity after sudden unidirectional perturbation is characterized by following parameters: the damping time (T), the Lehr's damping ratio (D), the orientation ratio (R) and the HeadPath during double-limb...
Gait analysis gets more accessible, accurate, and simple to use as technology advances. The goal of this paper is to explore the accuracy of an advanced optical motion analysis system, where marker clusters mounted on rigid shapes are used to track the movement of body segments. It aims to examine the magnitude and nature of variation of the angular gait parameters of the lower extremities, caused...
Stabilometry is the study of human postural stability. It can be used in clinical diagnosis and sport sciences as well. Expensive force distribution plates and force plates are used to these measurements. This paper validates the Nintendo Wii Balance Board for stabilometry measurements as a cheap alternative to the expensive force distribution plates. First the calibration of the sensor is described,...
