Muscle contributions to vertical and fore-aft accelerations are altered in subjects with crouch gait.
The goals of this study were to determine if the muscle contributions to vertical and fore-aft acceleration of the mass center differ between crouch gait and unimpaired gait and if these muscle contributions change with crouch severity. Examining muscle contributions to mass center acceleration provides insight into the roles of individual muscles during gait and can provide guidance for treatm...
متن کاملMuscle contributions to fore-aft and vertical body mass center accelerations over a range of running speeds.
Running is a bouncing gait in which the body mass center slows and lowers during the first half of the stance phase; the mass center is then accelerated forward and upward into flight during the second half of the stance phase. Muscle-driven simulations can be analyzed to determine how muscle forces accelerate the body mass center. However, muscle-driven simulations of running at different spee...
متن کاملMuscle contributions to support and progression during single-limb stance in crouch gait.
Pathological movement patterns like crouch gait are characterized by abnormal kinematics and muscle activations that alter how muscles support the body weight during walking. Individual muscles are often the target of interventions to improve crouch gait, yet the roles of individual muscles during crouch gait remain unknown. The goal of this study was to examine how muscles contribute to mass c...

T effectively combat invading pathogens, immune cells must rapidly switch from roughly spherical resting cells to polarized migratory ones, which then move in a directed fashion to the site of infection. The dramatic metamorphosis of leukocytes into polarized cells and their subsequent migration are two of the most fascinating phenomena in cell biology. Polarization and migration require the sp...
متن کاملMuscle Coordination and Energy Cost in Voluntary Crouch Gait
Introduction Crouch gait is a well known pathological gait pattern that is often present in diplegic children with a cerebral palsy, eg. [1]. Though the effect of crouch gait on muscle length and interventions at the muscular level on the crouch position are well studied [2,3], it is not known how changes in muscle kinetics are related to the changed posture and mechanisms of propulsion. Howeve...
