Biomechanical Orthotics [Mechanical engineering]

Biomechanical Orthotics

I have been in practice nearly 18 years and take great pride in the orthotics I dispense. Over the years I experimented with every brand, style, material and impression system available.

I have had the most success at altering a runner's abnormal time sequence responsible for their injury, be it from spending too much time in shock and converting to propulsion late or prematurely converting to propulsion when they should still be in shock absorption, with a suborthalene recoil plastic module, crepe/korex extrinsic posts, with a spenco full length top cover.

The most superior impression taking system I have found is the 90 degree, semi-weight bearing, resting calcaneal stance position into cast-o-foam, supported in the August 2000 issue of Biomechanics on page 72.

The walk over matts and grids that give peak plantar pressure and a colorful shape and picture of a patient's foot, in my experience, do not give enough information to build an equal correct time symmetry biomechanical orthotic. They seem to be a convenience system for the doctor to get patients in and out as fast as possible while at the same time, impressing patients with "high tech" bells and whistles.

I've replaced quite a few of these orthotics with their main reason for failing to relieve symptoms because the orthotics prescription was "watered" down and too weak to alter the patient back to correct time symmetry.

Maybe I'm old fashioned, but hand made is still the best, and I know solving a runner's biomechanical problem is a lot harder than walking across a pressure mat.

Your running injury is not caused by your running. It has a specific cause, or error, that must be found and corrected. It is important to treat the cause, not the effect, of the injury. For example, injuries of the foot, lower leg and knee are almost always due to a faulty time sequence. Fortunately, in expert hands, the injuries can be eliminated by correcting the abnormal biomechanics. A biomechanical approach works best because it corrects the roots of the problem: your foot type and time sequence. The treatments might include some of the following: The appropriate shoe style for your particular problem, orthotic inserts or heel lifts for leg-length inequalities. In knee injuries, it's best to start by ignoring the knee and treating the foot.

The Osborne Running Analysis Lab will provide you with the chance to see your running motion, velocity, cadence and stride length in order to take steps to enhance your running. One picture is worth a thousand words. Armed with the appropriate information, I can assess your particular problem and treat it.

What are Biomechanical Orthotics?

Biomechanics involves the study of body in motion. Biomechanical orthotics are prescription inserts made from neutral foot position casts or digital imaging. The prescribing practitioner sends the casts or digital image and clinical information to a professional orthotics laboratory, where an evaluation specialist reviews the casts and prescription. A staff doctor oversees the evaluation in the form of a "second opinion." Then a production clinician takes responsibility for fabrication and quality control of the individual prescription. The fabricated orthotics are sent to the doctor to…
