Falling poses a major threat to the steadily growing population of the elderly in modern-day
society. A major challenge in the prevention of falls is the identification of individuals who …

The popularity of using accelerometer-based systems to quantify human movement patterns
has increased in recent years for clinicians and researchers alike. The benefits of using …

This study quantified the relationships between local dynamic stability and variability during
continuous overground and treadmill walking. Stride-to-stride standard deviations were …

In the medical field, there is a need for small ambulatory sensor systems for measuring the
kinematics of body segments. Current methods for ambulatory measurement of body …

Traditional methods of describing human locomotion involve collecting gait data for a
number typically 5 to 10 of independent and isolated strides, time-normalizing the data from …

A ubiquitous characteristic of elderly and patients with gait disabilities is that they walk
slower than healthy controls. Many clinicians assume these patients walk slower to improve …

Falls not only present a considerable health threat, but the resulting treatment and loss of
working days also place a heavy economic burden on society. Gait instability is a major fall …

Gait parameters that can be measured with simple instrumentation may hold promise for
identifying individuals at risk of falling. Increased variability of gait is associated with …

Muscles actuate walking by providing vertical support and forward progression of the mass
center. To quantify muscle contributions to vertical support and forward progression (ie …

Traditional biomechanical analyses of human movement are generally derived from linear
mathematics. While these methods can be useful in many situations, they do not describe …
