The Optimal Functional Position is the most centered and balanced position of any foot at any given time. The OFP is dynamic in that the bones, joints, muscles, tendons and ligaments are constantly remodeling to adapt to the stresses that are applied to them.
All high arched, normal arched or low arched feet have their optimal functional position even though they may be too arched, normal arched or flat footed.
The Optimal Functional Position can degenerate, remain the same or improve when it comes to bony architecture, joint position and function and muscle unit strength, leverage and power depending on its architecture, its external support and its muscle engine strength, leverage and power.
Wellness Biomechanics® tries to improve upon a person’s individual, personal OFP by holding a foot in its current OFP with a Foot Centering Orthotic while training the primary muscle engines to fire with power and phase, injury free. The end result of this method of biomechanical treatment is that the patients Optimal Functional Position morphs into an even more optimal one as the foot type morphs into a healthier one.
The goal of Wellness Biomechancs is to improve every patients Optimal Functional Position towards a theoretical goal of ones structural, functional known as Foot Centered Position (FCP).
The Criteria for Foot Centered Position are:
- The bones of the foot have a limited range of motion in both the rear pillar and the fore pillar at foot contact maintained by the ligaments and well leveraged muscle units.
- The plantar fascia is a supportive ligament providing adequate support without producing pathological tissue stress.
- The Peroneus Longus Muscle is well leveraged at the rearfoot at foot contact so that the subject can have motor control as an effective primary muscle to lock the first ray and promote first ray rocker motion
- The Rearfoot is locked close to Vertical (STJ -2 to +2) to the weightbearing surface with no great deviation on the sagittal or transverse plane as the forefoot begins to bear weight
- The Posterior Tibial tendon is leveraged well under the navicular at foot contact.
- The Tendo Achilles is not active as a compensator throughout weightbearing and function
- The weightbearing, functioning foot rarely passes The Compensatory Threshold.
- The Long and Short Extensor muscles of the foot are not active as compensators throughout weightbearing and function.
- The Anterior Tibial muscle is well leveraged to support the medial column at foot contact.
- The Anterior Tibial muscle is not active as a compensator throughout weightbearing and function.
- The fifth ray is well leveraged at foot contact
- Peroneus Brevis is well leveraged at fifth metatarsal contact
- The Keystone of The Vault of the Foot is locked close to Foot Centered Position (OFP) and is well maintained by the ligaments and well leveraged muscle units
