Preliminary study on the design of a low-cost movement analysis system: reliability measurement of Timed Up and Go test
International audience; In this paper, we present experiments on the design of a novel movement analysis system for real-time balance assessment in the frail elderly. Using the Microsoft Kinect sensors, we capture TUG (Timed Up and Go) tests and analyze mainly the transfer from sitting-to-standing and back-to-sitting which represent two of the most commonly executed human movements. Nine spatio-temporal parameters were extracted from recorded joint positions by 3D skeletal sequence processing. In order to validate and evaluate the developed system, practical test experiences have been performed on ten healthy young subjects, who were asked to realize the TUG in three different conditions: n…

Practice-Related Improvements in Postural Control During Rapid Arm Movement in Older Adults: A Preliminary Study
International audience; Background. Postural control associated with self-paced movement is critical for balance in older adults. The present study aimed to investigate the effects of a virtual reality based program on the postural control associated with rapid arm movement in this population. Methods. From an upright standing position, participants performed rapid arm raising movements toward a target. Practice-related changes were assessed by pre- and posttest comparisons of hand kinematics and center of pressure displacement parameters measured in a training group (mean age: 71.50 +/- 2.67 years, n = 8) and a control group (mean age: 72.87 +/- 3.09 years, n = 8). Training group participa…
