Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The ankle and foot provide the foundation for the body and the stability needed for upright posture and ambulation. Because of its weight-bearing function, the ankle joint is a common site of injury among athletes and in the general population. Ankle injuries occur as a result of both acute trauma and repetitive overuse (such as running). The ankle is a fairly simple joint, consisting of the articulation between the...

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints. Here are some common anatomical movements: Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
FAQs
Dorsiflexion and plantarflexion allow the foot to be repositioned relative to the lower leg as the body maintains posture or moves through the environment. Their coordinated use helps regulate how the body responds during locomotion and balance tasks. In behavioral studies, examining these motions can reveal differences in motor coordination and movement control across tasks.
Sensory receptors provide information about body position and changing environmental demands, while the nervous system uses that information to coordinate force and timing. This interaction allows movement to be adjusted rather than produced as a fixed pattern. Measuring responses during altered surfaces or tasks can therefore show how an organism adapts its motor behavior.
Muscles and tendons help generate and transmit the forces needed to control ankle motion. Their coordination with sensory information and nervous-system signals determines when movement occurs and how strongly it is produced. This relationship is important when studying posture, gait, and balance because observed ankle behavior reflects both mechanical force production and nervous-system timing.
Researchers examine ankle movement while participants or animals perform behaviors such as walking, maintaining balance, or responding to changing surfaces and tasks. Measurements can then be used to characterize motion, coordination, and balance strategies under different conditions. Comparing these movement patterns helps connect observable behavior with the control processes supporting posture and locomotion.
Ankle movement measurements can identify how effectively an individual coordinates force and timing during gait, balance, and other locomotor behaviors. They may also show how movement strategies change when environmental demands vary. In behavioral research, these outcomes help assess motor impairments and clarify how humans or other animals adjust movement to maintain effective performance.
These studies are useful when researchers need to characterize altered gait, balance strategies, or motor coordination and relate those patterns to functional behavior. Findings can support assessment of motor impairments, rehabilitation planning, and the development of assistive devices. The same measurements also provide behavioral context for evaluating whether movement control improves across tasks or environmental demands.
