This protocol presents a testing system used to induce quantifiable and controlled fatigue injuries in a rat Achilles tendon for an in-vivo model of overuse-induced tendinopathy. The procedure consists of securing the rat's ankle to a joint actuator that performs passive ankle dorsiflexion with a custom-written MATLAB script.

Isolated Musculus gastrocnemius tightness is a common cause for foot and ankle pathologies. Currently no standardized examination procedure exists. This manuscript demonstrates that 20 degree of knee flexion eliminates the restraining effect of the M. gastrocnemius on ankle dorsiflexion and presents a video description of a standardized examination protocol.

An in vivo animal model of injury is described. The method takes advantage of the subcutaneous position of the fibular nerve. Velocity, timing of muscle activation, and arc of motion are all pre-determined and synchronized using commercial software. Post injury changes are monitored in vivo using MR imaging/spectroscopy.

Ankle Exam

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...
FAQs
The opposing actions of dorsiflexion and plantarflexion allow the ankle to adjust foot position rather than remain fixed. Their coordinated use helps the foot respond to changing demands during standing and walking, while also supporting the control of forces. This coordination is important because ankle motion must contribute to both stability and forward movement during weight-bearing activity.
Effective ankle movement depends on coordinated activity among the muscles that produce dorsiflexion and plantarflexion. The tibialis anterior, gastrocnemius, and soleus contribute to different movement directions, so their combined activity influences foot placement, force control, and propulsion. Studying this coordination can reveal how altered muscle function contributes to weakness, restricted movement, or changes in gait.
Dorsiflexion and plantarflexion help manage the interaction between the foot and the ground during weight-bearing movement. Their combined action supports foot placement, contributes to absorption of forces, and helps generate propulsion. Because these tasks also affect balance, changes in ankle range or muscle coordination may influence how effectively a person stands or walks.
Researchers assess the range of motion available in both opposing ankle directions and consider how that movement relates to muscle coordination. The findings help characterize normal biomechanics and identify movement limitations. In rehabilitation research, range-of-motion assessment can also help examine ankle injuries, weakness, altered gait, and other conditions that affect functional movement.
Assessment of dorsiflexion and plantarflexion can show whether foot placement, force control, and propulsion are functioning as expected during walking. When movement is limited or muscle coordination is altered, the resulting findings may help researchers investigate changes in gait. This makes ankle assessment useful for connecting observable walking patterns with underlying biomechanical limitations.
They are especially relevant when researchers investigate ankle injuries, weakness, altered gait, or limitations in movement. Measuring available motion and examining muscle coordination provides information about how those conditions affect standing and walking. The same measures can support evaluation of rehabilitation needs by showing changes in the ankle functions that contribute to balance, force absorption, and propulsion.
