Falls and freezing of gait are two “episodic” phenomena that are common in Parkinson's
disease. Both symptoms are often incapacitating for affected patients, as the associated …

Postural instability and falls are common and devastating features of ageing and many
neurological, visual, vestibular or orthopedic disorders. Current management of these …

Drawing on the disciplines of neurophysiology and physics, Neuromechanics of Human
Movement, Fourth Edition, explores how the nervous system controls the actions of muscles …

Background: balancing reactions that involve rapid stepping or reaching movements are
critical for preventing falls. These compensatory reactions are much more rapid than …

The purpose of this study was to determine whether and why subjects with Parkinson's
disease (PD) have greater instability in response to specific directions of perturbations than …

One of the most widely conserved hallmarks of aging is a decline in functional capabilities.
Mobility loss is particularly burdensome due to its association with negative health …

An increased susceptibility to falling leading to functional disability is one of the major
problems associated with human aging. Even in the absence of injury resulting from falling …

The purpose of this study was to compare the acute effects of three different stretching
protocols on balance, agility, reaction time and movement time of the upper limbs …

The equations of motion for a standing multi-segment human model are derived. Output
quantity of these equations is the horizontal acceleration of the whole-body centre of mass …

Classical studies in animal preparations suggest a strong role for spinal control of posture. In
humans it is now established that the cerebral cortex contributes to postural control of …
