Exam 10: Clinical and Sport Biomechanics

The division of the body into three imaginary cardinal planes allows for a reference of biomechanical movements into three dimensions: sagittal, frontal, and transverse.

Clinical biomechanists work with other health care providers, such as physicians and physical and occupational therapists, to help individuals return to normal function as quickly as possible.

Linear motion occurs when all points on a body move in a parallel line the same distance, but the paths followed by the points on the object are curved and there is no change in body orientation.

__________ work primarily to prevent workplace injuries and improve the capacity for the individual to return to work after an injury has occurred by modifying the workplace environment.

A qualitative analysis requires the progressive identification of the aspects critical to the movement or motor skill.

When an eccentric or nonaxial force is applied to a structure, the structure bends, creating sheer stress on one side and diffuse stress on the opposite side.

If the amount of force applied to the body causes the deformation of the body tissues to exceed the point at which change to the structure occurs, some amount of deformation becomes permanent and is referred to as an injury.

__________ describes how segments of the body and joint movements occur in a specific sequence.

The reference system most commonly used in biomechanics is a Cartesian coordinate system in which units are measured in the direction of one primary axes.

Success in throwing, hitting, or catching projectiles ultimately depends on the projectile's release velocity, angle of projection, and the height of the release.

The development of individualized rehabilitation techniques, wheelchair design, tissue repair, surgical techniques, and bone and tissue designs are examples of activities performed by:

Although many allied health care professionals are employing the use of video recordings, visual observation remains the most commonly used approach for qualitatively analyzing the mechanics of human movement.

Sport biomechanists work with athletic coaches to identify neuromuscular and mechanical factors associated with human movement to describe the requirements necessary for an athlete to perform at an optimal level.

__________ describes the plane of the body which divides the top half from the bottom half.

__________ is the study of bodies, masses, and forces when they are speeding up or slowing down.

Using proper technique to perform a task often produces disabling injuries to active and supporting tissues and muscles.

__________ occurs when a structure is caused to twist around its longitudinal axis.

A correct and complete biomechanical analysis of a movement or skill requires that the system of interest be operationally defined.

External forces acting on an object impose a mechanical load on the object.

During a biomechanical analysis of a body movement or sport skill, it is often useful to employ a fixed system of reference called:
