Bio-Mechanical Composites, Inc

Bio-Mechanical Composites, Inc. (BMC) is the leader of State of the art Custom Composite fabrication in the O&P industry. While there are a number of companies that make various designs of orthoses with Carbon Fiber; BMC has 20 years of experience that has developed into a Superior Orthotic System.

Different designs of orthosis have different functions they can produce. But the real success to the patient is in making any particular design with the correct amount of Resistance that matches the patients deficits. Over the years BMC has developed Extremely Specific fabrication techniques. Creating the most consistent quality composite orthosis in the industry.

Even the best design, with the right resistances, will be unsuccessful if it is Uncomfortable. Only when, the Patient is Comfortable, does the right resistances and the correct design allow the patient to achieves the best outcomes.

BMC’s years of experience have produced the Best Fit in the Industry.

Fabrication Processes:

In an assembly line system of fabrication, BMC is able to maintain the highest standards in composite fabrication. All while producing Orthoses and Prostheses that produce consistent functional outcome for the patient. With 18 years of experience, the comfort and fit of the patient is the best in the country. The system includes Input communication and education with practitioners. This is based on developing protocols that increase the functional outcomes for the patient served. With tens of thousands of custom designs produced, we have maintained less than 10% re-manufacturing rate over the last 18 years. “Do it right the first time” is our Motto…

Energy Storing:

Carbon fiber composites can produce a long flat structure that stores energy. This means that as the structure is bent a few degrees, it pushes back. Bending it a few more degrees and the push back increases rapidly. BMC has developed Orthosis and Prosthesis designs that utilize this to replace the function of the calf muscle. This functions in three areas. It produces propulsion in walking, standing balance and Queuing/Stabilization of the knee during walking. In higher levels it can also be ramped up for more extreme activities, such as running and jumping.

Functional Outcomes:

Standing Balance

Standing Balance

The ability to stand and balance without holding on to something.



The push-off or plantar flexion motion of the foot, during mid to late stance phase of walking.

Knee Stabilization

Knee Stabilization

The posteriorly directed force at the knee that maintains a slightly flexed (2 degree) position, that allows the knee to support the weight of the body.

It is very difficult to see calf strength weakness/absence while watching someone walk. To the patient, the return of this function is tremendous.

While a fully or hyper extended position creates a lock out or abnormal walking pattern. A excessively flexed knee, creates a crouched and inefficient walking pattern.

The Energy Storing Orthosis designs we’ve created provided all three of these functions simultaneously. This replacement of the calf functions brings the patient back to a near normal walking pattern. Accordingly this is dependent on a thorough evaluation of the patient particular deficit level. This determines the specific strength of the Carbon structure, to be the most effective for the patient. It is also dependent on the proper positioning in the casting of the patient. This determines the timing of when the force of the orthosis acts against the patient; in standing and in their walking cycle.
