Multibody software designed for mechanical engineering has been successfully employed
in biomedical research for many years. For real time operation some biomedical researchers …

Movement is fundamental to human and animal life, emerging through interaction of
complex neural, muscular, and skeletal systems. Study of movement draws from and …

Computational modeling and simulation of neuromusculoskeletal (NMS) systems enables
researchers and clinicians to study the complex dynamics underlying human and animal …

Muscles actuate running by developing forces that propel the body forward while supporting
the body's weight. To understand how muscles contribute to propulsion (ie, forward …

Humans run faster by increasing a combination of stride length and stride frequency. In slow
and medium-paced running, stride length is increased by exerting larger support forces …

Crouch gait, a common walking pattern in individuals with cerebral palsy, is characterized by
excessive flexion of the hip and knee. Many subjects with crouch gait experience knee pain …

Movement science is driven by observation, but observation alone cannot elucidate
principles of human and animal movement. Biomechanical modeling and computer …

Musculoskeletal tissues respond to optimal mechanical signals (eg, strains) through
anabolic adaptations, while mechanical signals above and below optimal levels cause …

The complexity of shoulder mechanics combined with the movement of skin relative to the
scapula makes it difficult to measure shoulder kinematics with sufficient accuracy to …

We explored the tibiofemoral contact forces and the relative contributions of muscles and
external loads to those contact forces during various gait tasks. Second, we assessed the …
