The assessment of sensorimotor functions is extremely important to understand the health
status of a patient and its change over time. Assessments are necessary to plan and adjust …

Written by the foremost authority on the subject, Kinetics of Human Motion is the sequel and
companion to the 1998 text Kinematics of Human Motion. World-renowned biomechanics …

A scheme for understanding the organization of human postural movements is developed in
the format of a position paper. The structural characteristics of the body and the geometry of …

When humans hop in place or run forward, leg stiffness is increased to offset reductions in
surface stiffness, allowing the global kinematics and mechanics to remain the same on all …

Recent epidemiological studies report that obesity is positively related to fracture incidence.
In the present experiment, a model of postural control was used to examine the impact of an …

The non-disabled human ankle joint was examined during walking in an attempt to
determine overall system characteristics for use in the design of ankle prostheses. The …

Human joint impedance is the dynamic relationship between the differential change in the
position of a perturbed joint and the corresponding response torque; it is a fundamental …

In human locomotion, we continuously modulate joint mechanical impedance of the lower
limb (hip, knee, and ankle) either voluntarily or reflexively to accommodate environmental …

A parallel-cascade system identification method was used to identify intrinsic and reflex
contributions to dynamic ankle stiffness over a wide range of tonic voluntary contraction …

As muscle is stretched, it reacts with increasing passive resistance. This passive force
component is important for normal muscle function. Unfortunately, direct measurement of …
