Though all designed for the same essential function, human feet vary significantly in their structure between individuals. The most significant difference in foot structure is the arch, referring to the curve between the ball of your foot and the pad on your heel. The foot arch can range from a very high visible arch all the way to what is considered flat feet, with no visible arch and almost the entire sole of the foot making contact with the ground. This difference in structure changes the biomechanics of the foot, in turn changing the way we walk, run, jump, and complete any athletic feat. So how exactly do our arches play into athletic performance?

The 21,000 lb Question – How Elephants Defy Logic Through Locomotion
One of the most prominent questions in the engineering industry is how to build something that lasts. The biomechanics of elephant locomotion gives an example of near engineering perfection stemming from biology itself – with each foot supporting thousands of pounds of weight consistently and without failure while also maintaining mobility.

How do pressure profiles and shear stresses in prosthetic sockets affect prosthesis user comfort? For prosthesis users, comfort is essential for mobility, quality of life, and long-term health. The fit and alignment of a prosthesis are highly individualized and crucial for instilling confidence in daily activities. However, current prosthesis fittings are largely subjective, depending on the prosthetist’s experience and user feedback. This qualitative method often overlooks the critical factor of pressure distribution within the socket, which can significantly impact pain levels and ease of movement.

Parkinson’s disease is the second most common neurodegenerative disease with 90,000 Americans being diagnosed every year. Parkinson’s is a difficult disease to detect; there are no blood or lab test to diagnosis it. Diagnoses are symptom based. Parkinson’s patients often do not know they have the disease until after having dealt with it for years. Some of the early symptoms such as facial masking (lack of facial expression), small handwriting, or speaking softly do not directly point to a Parkinson’s disease diagnoses. A patient comes in with tremors, muscle rigidity, poor balance, and slowed movements and are then assumed to have Parkinson’s disease. If their symptoms improve with medication, the diagnosis is confirmed. Biomechanics is a useful tool in the evaluation of the progression of the disease as well as its continued treatment.

The lymphatic system is a system of vessels and lymph nodes that runs parallel to our vascular system. It takes up extra fluid from around our cells, filters it, and returns the liquid to our circulatory system. When part of the lymphatic system is damaged by surgery, radiation treatments, or injury, a progressive disease called lymphedema can occur.

Seeing a giraffe for the first time, one is amazed by their long necks and long legs, but do you ever wonder how their long skinny legs can support their large body mass as they move about? Studies have shown that a giraffe’s legs undergo a large ground reaction force when walking freely and an even larger ground reaction force when moving at a faster speed than walking.

Have you ever wondered how your arch type may affect your everyday life especially in physical activities such as running or playing sports? Well it turns out that without taking precautions, a higher arch or a flat foot may cause you to more likely be injured! People have all different types of arches, and each foot can be affected differently based on the type of arch.

From Christmas movies to pop songs to motivational posters, we are encouraged to keep putting “one foot in front of the other.” While the sentiment is inspiring, recent studies show that there is a lot more to the seemingly simple task of walking than this phrase would suggest. Understanding this is especially important for balance and mobility after an injury or as people age.
