The Timed Up & Go (TUG) test is a simple test for gait and balance that requires no special equipment and can be part of a routine clinical examination. Combined with the development of motion capture technologies, the possibilities of assessing individual TUG sub-components (i.e. sit-to-stand, gait, turn, turn-to-sit) are increasing. The clinical evaluation of an instrumented TUG requires reliable...
The article focuses on a method of quantifying movement of patients with Parkinson's disease (PD) using wearable motion capture (MoCap) system and bilateral cyclograms. The method uses cyclogram characteristics such as the slope, second moment of area and the area of the cyclogram to compare movements of left and right side of body. For symmetric movement, cyclogram should lie on a symmetry line passing...
The article focuses on a technique of quantifying movement of patients with Parkinson's disease (PD) using accelerometers and method based on eigenvectors. The method uses trend symmetry to compare acceleration's waveforms of left and right side of body. The trend symmetry value is calculated as a ratio of the variabilities of two eigenvectors, which are calculated from the kinematic motion data of...
