Being light, strong, and small, and yet functional and durable is the challenge.Early designs for prosthetic feet were often a solid piece of wood.If a practitioner or therapist has not yet identified your activity level, here are some very basic indications.Tags: Biology AssignmentConstantine And Christianity EssayRomeo And Juliet Thesis PaperProposed Research Project ExamplePink Flamingo Ap EssayPersuasive Essay On Std
A good prosthetic foot should also be strong, as it will be taking on huge force and torque as you walk and run.
Feet must also be small enough to fit within a foot shell, a cosmetic covering for the prosthetic foot, and thus fit within a shoe.
For people who cannot walk, the function is largely cosmetic.
For those who are most active, a prosthetic foot must mimic a normal foot during the act of walking.
Carbon fiber feet meet the functional needs for shock absorption and energy efficiency, and are lightweight as well. A prosthetic foot has to feel good for you to meet your activity goals.
Comfort allows you to be more active, and the function of your prosthetic foot directly affects comfort. Prosthetic feet are designed to mimic a human foot at a specific activity level.Some prostheses have one spring in the heel and a second spring in the forefoot: just what you need for walking at various speeds, running, climbing hills or descending stairs with a secure, confident stride.With carbon fiber, the longer the spring, the more energy it can store and the more responsive the foot will be.The cosmetic shell, which stretches around the foot prosthesis and is held in place, serves two purposes: What’s inside the shell can vary dramatically. The materials in a prosthetic foot differ by activity level.Prosthetic feet are designed to meet the needs that fit your lifestyle and activity level. Wood, plastic and foam are usually found in feet designed for individuals who have low activity levels and require stability.Ideally the foot will be light because its weight is added to the rest of the leg prosthesis.If the foot is too heavy, the suspension system may be affected and with it the connection to the socket and your limb.For an amputation above the ankle, a standard prosthetic foot can meet your needs.You should consider multi-axial capability as well as shock absorption.Activity Level 1For those with the most limited mobility, prosthetic feet designed for maximum stability help maintain balance when standing or taking short, cautious steps at minimal speed on level floors.With safety as a priority, opt for these characteristics in a prosthetic foot: Activity Level 2To walk for a limited time and limited speed and be able to negotiate obstacles like curbs or uneven ground, you would benefit from a prosthetic foot that offers stability and comfort, meaning it protects the joints and residual-limb tissue.
