2025
This protocol presents a step-by-step instruction for harvesting the superficial inferior epigastric artery fascia (SIEF) flap and wrapping it around the reconstructed peroneal nerve defect in rabbits. This surgical addition of vascularization to the tissue bed of nerve grafts is used to improve regeneration outcomes.

Construction of Constant-Load (Isotonic) and Constant-Velocity (Isokinetic) Torque-Velocity-Power Profiles In vivo for the Rat Plantar Flexors

2025
Here, we present a novel protocol to non-invasively measure the torque-angular velocity-power relationship in vivo in rat plantar flexors using transcutaneous muscle stimulation. This setup enables simple testing of isotonic muscle contractions on a force transducer/length controller system to better represent the constant-load nature of everyday movements.

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The foot is a complex structure composed of numerous bones and articulations. It provides flexibility, is the essential contact point needed for ambulation, and is uniquely suited to absorb shock. Because the foot must support the weight of the entire body, it is prone to injury and pain. When examining the foot, it is important to remove shoes and socks on both sides, so that the entire foot can be inspected and compared.

(2023).This video demonstrates a procedure to generate a rat tibial neuroma transposition (TNT) model. After exposing the tibial nerve in the hind leg of an anesthetized rat, transect the nerve. Next, create a subcutaneous tunnel, thread the severed nerve through the tunnel, and suture it in place. In the absence of a target for reinnervation, disorganized axonal...
FAQs
Toe dorsiflexion tensions the plantar fascia through the windlass mechanism, which elevates the medial arch and helps convert the foot into a stable platform for push-off. This change is important because the tissue does more than passively support the sole: its tension links toe motion with arch behavior during walking. Clinicians consider this relationship when evaluating foot function.
The attachment pattern from the calcaneus to the bases of the toes allows tension generated near the forefoot to influence the arch and heel region. This continuous arrangement helps explain why toe dorsiflexion, arch elevation, and push-off are mechanically linked. In clinical reasoning, the anatomy provides a framework for interpreting pain or functional changes along the sole.
During standing and walking, the plantar fascia helps distribute forces through the foot while contributing to medial-arch support. Its function therefore depends on both tissue continuity and the mechanical demands placed on the foot. Examining how the arch responds to loading and movement can help clinicians connect symptoms with altered foot mechanics rather than considering heel pain in isolation.
Clinical assessment combines physical examination with imaging when evaluating heel pain, particularly plantar fasciitis. Together, these approaches can inform clinicians about plantar fascia structure and function, then help guide management. Their value lies in connecting observable findings with decisions about stretching, load management, footwear changes, or other treatments.
Findings can help clinicians determine which strategies to consider for heel pain, including stretching, load management, footwear changes, or other treatments. Because the plantar fascia contributes to arch support and force distribution, management planning can account for both symptoms and mechanical function. This approach also supports more targeted rehabilitation planning.
Biomechanical understanding helps rehabilitation planning by linking tissue function with the demands of standing, walking, and push-off. Clinicians can use that relationship to interpret how heel pain may affect foot stability and to select management strategies such as stretching, load management, or footwear changes. This supports care that addresses function as well as symptoms.
