Biomedical sciences rely heavily on devices to acquire and analyze the physiological data needed to understand and model the biological processes of humans and animals. Therefore, the results of the investigations, clinical or academic, depend heavily on the instrumentation used. Unfortunately, all too often the users do not understand their instruments and(More)
OBJECTIVE This study evaluates methods to optimize the trunk center of mass position, the center of pressure position, or both to minimize the difference between horizontal location of the whole body center of mass estimated by the model and center of pressure measured during static postures. DESIGN Within subjects repeated measures. BACKGROUND Methods(More)
When repeating tests on a subject it is important to know if changes of the results are significant. Researchers have used measures of reliability, e.g., intraclass correlation coefficient (ICC) and minimum detectable change (MDC), to assess reliability and validity of balance measures and equipment, and to determine what constitutes a significant change(More)
Computerized posturography systems are commonly used to evaluate postural equilibrium and balance, usually performing a static balance test in which the person being tested tries to minimize the sway of the body. Most variations of static test are part of the modified Clinical Test of Sensor Integration in Balance (mCTSIB) test protocol. Given its(More)
In an effort to investigate the mechanics of drop landing on a flat surface, bilateral performance characteristics during the landing were investigated. Two force plates were used as landing surfaces, and the six component kinetic time histories and the path of the center of pressure were measured for both feet. The forces were combined to obtain the(More)
Simulation is becoming an increasingly accepted method for training personnel for complex or high risk tasks. With the advent of modern Virtual Reality (VR) technology, such simulations are becoming more and more immersive. One significant limitation to the advance of this science is the challenges associated with simulating the touch or feel of various(More)
PURPOSE One aim of this study was to find if there was a difference between balance and stability between elite level gymnasts and non-gymnasts. Another aim was to find if there was a relationship between dynamic posturographic scores associated with sway fatigue or adaptability and the ability to learn new gymnastic routines. The ultimate aim of the study(More)
On "Comparison of a laboratory grade force platform with a Nintendo Wii Balance Board on measurement of postural control in single-leg stance balance tasks" by Huurnink, A., et al. [J. Biomech 46(7) (2013) 1392]: Are the conclusions stated by the authors justified? We read with great interest the work by Huurnink and colleagues and we would like to offer(More)
OBJECTIVES The aim of this study was to ascertain whether listening to music might cause changes in human stability and be useful in fall prevention and rehabilitation. The aim was also to find what percentage of subjects without neurologic signs or symptoms associated with falling had less than ideal stability. DESIGN Computer dynamic posturography (CDP)(More)
The ability to capture analog signals in a digital format suitable for subsequent storage, processing and analysis by a computer has revolutionized many scientific fields, including biomechanics. In the process of going from the analog signal to its digital representation, it is essential to maintain as much of the original signal content as possible. There(More)
