Symbionic Leg

The Symbionic Leg is a completely bionic leg for above knee amputees which combines a microprocessor knee and foot seamlessly. This leg allows amputees to explore all terrains safely without the user needing to compensate in any way.

Subatmospheric Socket Technology

Brimless transfemoral sockets are more comfortable, feel more secure and are easier to manage, even in high activity. Flexible socket materials are used in a design that doesn’t push on the pelvis. Our vacuum suspension and new liner materials also improve range of motion and volume control.

Genium Knee

Breakthrough technology and functionality come together in the latest microprocessor controlled prosthetic knee. As an above-knee amputee, the Genium knee is all you could ask for in a prosthetic device. Dynamic stability, water resistant, more compact size, a gyroscope sensor and 5-day battery life are some of the features that make the Genium stand out.

BiOM Foot

The BiOM technology platform is the first true personal bionics solution. By mimicking muscles and tendons, the BiOM Systems enable smooth, natural human movement. The artificial muscle power allows people to walk with the same gait and the same effort as non-amputees. The BiOM Ankle System instantly improves function, empowering people to do the things they want at their chosen speed with (1) less energy requirements, (2) decreased joint degeneration and (3) fewer aches and pains.

Power Knee

The first and only motor-powered prosthetic knee, the POWER KNEE works as an integrated extension of the user, designed to restore the power of lost muscles and symmetry of movement that is vital for those with limb loss. POWER KNEE gives users the ability to cover greater distances than they could previously.

Confidently negotiating obstacles and inclines has never been easier. With the POWER KNEE ascending stairs foot-over-foot is now possible.

Computer-Aided Design And Manufacturing cad cam


Our Computer Aided Design (CAD)/Computer Aided Manufacturing (CAM) system is used to create prosthetic limbs with accuracy and efficiency. At Scheck & Siress, our prosthetists may use CAD to scan a patient’s residual limb and then send that information to our central fabrication partner, Advanced Orthotic & Prosthetic Systems who will manufacture the limb using CAM and their electronic carver.

What Are Bionic Limbs?

Bionic limbs are artificial limbs that work by using signals from an individual’s muscles to seamlessly move. Some bionic limbs also rely on electrical signals from the brain and nerves in order to create the proper movements. These limbs, such as bionic hands, are either electronically or mechanically powered, with some bionic options relying on a combination of both. Whereas traditional prosthetic limbs require complete body power to work, bionic limbs provide much more support and capability by using both muscles and the brain to power them.

How Do Bionic Limbs Work?

Bionic limbs typically work by detecting signals from the user’s muscles. For example, when a person puts on their bionic limb and flexes the muscles above or below the limb, sensors will react to elicit the appropriate movement. Bionic limbs are often equipped with sensors to detect these muscle movements. So, for example, say you have a bionic arm. When you put on the arm, you flex the muscles you normally would to open your hand. This sends a signal to the sensors in the bionic arm to flex the hand.

Most bionic limbs have built-in computers that detect the muscle signals. Some bionic limbs require sensors to be implanted into the remaining muscles of the limb stump. This type of bionic limb is much more advanced and can allow users to control the limb with their minds. For example, you may think about moving your leg and your bionic leg will respond by moving.

Many bionic limbs are considered “plug and play,” which means they can be put on and taken off with ease and used only when needed. Bionic limbs do not require surgery to work, but many limbs are custom-built to the specifications of the users’ muscles.

This type of prosthetic limb gives users maximum control and adapts to how quickly or slowly the muscles tense. When the muscles are tensed more gently, the bionic limb will respond slower. When muscles are tensed quickly, the limb will react faster.

What’s the Difference Between a Prosthetic Limb and a Bionic Limb?

There is a significant difference between prosthetic and bionic limbs. Cosmetic prosthetic limbs, which are the basic prosthetic products available, provide very little or no functionality and are simply worn to give a natural appearance of a limb. These limbs are not able to actively move, and they require the user to rely on their body to move the limb.

Functional prosthetics are a step up from cosmetic or passive prosthetics but still require body power to move. Functional prosthetics are typically available in both body-powered and electrically powered forms, with the electrically powered option relying on batteries and motors to power movements. This type of prosthetic will react based on detected muscle movements in the residual limb or upper body.

A bionic limb gives the user much more control and movement through the use of sensors and computers that respond to both thoughts and muscle movement. This functionality takes much of the workload off of the user’s body and acts more like a real limb. Ultimately, bionic limbs provide much more ease and functionality when compared to traditional prosthetic limbs and require less effort from the user.

Types of Bionic Limbs

There are several types of bionic limbs available, and the type you choose should be based on your overall mobility goals. The following are a few bionic limb options to consider:

iLimb and iLimb Digits

There are several iLimb and iLimb Digits options to choose from. These bionic limbs are multi-articulating prosthetic hands and digits that include individually motorized digits as well as a manually rotating thumb. These bionic hands are lightweight and easy to use, and they also offer several functions that give users more hand functionality.

Symbionic Leg

The Symbionic Leg is a bionic leg that uses both a microprocessor foot and knee for seamless movement. This 100% bionic leg is made for individuals with above-knee amputations and gives users the ability to walk or run on various terrains without requiring any compensation on the user’s behalf.

BiOM Foot

The BiOM Foot offers advanced bionic technology for seamless walking and foot movement. This bionic limb features the BiOM System, which mimics tendons and muscles for natural human movement. In fact, users will have the same gait as individuals without a prosthetic foot. The BiOM Foot is equipped with the BiOM Ankle System for energy requirements and decreased pains, aches, and joint degeneration.
