The windlass test is a simple clinical method used to examine how the plantar fascia behaves when the big toe is raised and the arch is placed under tension. During this movement, a podiatrist gently lifts the big toe while keeping the foot steady, allowing them to see whether the plantar fascia tightens normally or triggers discomfort. This test is most often associated with plantar fasciitis because people with this condition frequently feel heel or arch pain when the toe is elevated. It can also provide helpful information about flat feet, arch fatigue, or other mechanical issues that affect daily movement. The windlass test is usually performed when someone reports morning foot pain, stiffness, or tenderness along the bottom of the foot. If these symptoms persist or interfere with routine activity, it is suggested that you see a podiatrist for effective relief and treatment solutions.

If you have any concerns about your feet, contact Dr. Rouder from S.I. Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Biomechanics in Podiatry

Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.

A History of Biomechanics

  • Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
  • In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.

Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.

Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Weill Marchesani Syndrome is a rare genetic condition best known for its impact on the eyes, joints, and overall body structure, yet it can also influence foot mechanics in ways that affect mobility and daily comfort. Individuals with this condition often have short, broad hands and feet, along with stiff joints that limit flexibility. When the joints of the feet are less mobile, walking can place extra strain on the arches, heels, and forefoot. Some people develop a flat foot structure or experience difficulty with balance because the feet cannot adapt easily to different surfaces. Tightness in the tendons may contribute to discomfort during activity, while reduced joint motion can lead to early fatigue or altered gait patterns. A podiatrist can help by evaluating foot alignment, identifying pressure points, and recommending supportive footwear or custom orthotics to improve comfort and stability. If you have this rare disease, it is suggested that you get regular foot monitoring by a podiatrist to prevent secondary issues such as calluses, tendon strain, or joint pain.

Some foot conditions may require additional professional care. If you have any concerns, contact Dr. Rouder of S.I. Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Rare Foot Conditions

The majority of foot conditions are common and can be treated by a podiatrist.  Standard diagnostic procedures are generally used to identify specific conditions and treatment can be rendered. A podiatrist also treats rare foot conditions which can be difficult to diagnose and may need extra attention and care. 

There are many rare foot conditions that can affect children. Some of these can include:

  • Freiberg’s disease
  • Kohler’s disease
  • Maffucci syndrome

Freiberg’s disease - This can be seen as a deterioration and flattening of a metatarsal bone that exists in the ball of the foot. It typically affects pre-teen and teenage girls, but can affect anyone at any age. Symptoms that can accompany this can be swelling, stiffness, and the patient may limp. 

Kohler’s disease - This often targets the bone in the arch of the foot and affects younger boys. It can lead to an interruption of the blood supply which ultimately can lead to bone deterioration. The patient may limp or experience tenderness, swelling, and redness.

Maffucci syndrome - This affects the long bones in a child’s foot leading to the development of abnormal bone lesions. They are benign growths and typically develop in early childhood and the bones may be susceptible to breaking. 

A podiatrist can properly diagnose and treat all types of rare foot conditions. If your child is affected by any of these symptoms or conditions, please don’t hesitate to call our office so the correct treatment method can begin.

Flat feet, also known as fallen arches, occur when the arches of the feet collapse or fail to develop properly, causing the soles to make full contact with the ground. Symptoms include foot fatigue, aching in the arches or heels, ankle instability, swelling, and pain that can extend to the knees or lower back. Common causes include genetics, ligament laxity, injury, obesity, aging, or conditions that weaken the foot structures. Flat feet may also develop over time from prolonged standing or wearing improper footwear. A podiatrist can help by evaluating foot alignment and gait, providing custom orthotics, recommending supportive shoes, and creating a treatment plan to reduce pain and improve function. If you have flat feet and are experiencing foot pain or fatigue, it is suggested that you consult a podiatrist who can offer effective relief and management tips.

Flatfoot is a condition many people suffer from. If you have flat feet, contact Dr. Rouder from S.I. Podiatry. Our doctor will treat your foot and ankle needs.

What Are Flat Feet?

Flatfoot is a condition in which the arch of the foot is depressed and the sole of the foot is almost completely in contact with the ground. About 20-30% of the population generally has flat feet because their arches never formed during growth.

Conditions & Problems:

Having flat feet makes it difficult to run or walk because of the stress placed on the ankles.

Alignment – The general alignment of your legs can be disrupted, because the ankles move inward which can cause major discomfort.

Knees – If you have complications with your knees, flat feet can be a contributor to arthritis in that area.  

Symptoms

  • Pain around the heel or arch area
  • Trouble standing on the tip toe
  • Swelling around the inside of the ankle
  • Flat look to one or both feet
  • Having your shoes feel uneven when worn

Treatment

If you are experiencing pain and stress on the foot you may weaken the posterior tibial tendon, which runs around the inside of the ankle.
