Faulty Biomechanics Of The Lower Extremities, How A Simple Biomechanics Dysfunction Accelerates The Aging Process, The 10th International Congress On Anti-Aging and Biomedical Technologies,

Faulty Biomechanics of the Lower Extremities: A presentation of how a simple biomechanical dysfunction accelerates the aging

process. The most effective diagnosis, treatment and prevention.

James Stoxen, D.C. President, Team Doctors Treatment Centers

Discussion of anti- aging issues with lack of care and how the body ages more rapidly with the cascading domino effect of this syndrome. We will discuss the risks and complications of the development of more life threatening diseases, which can manifest from the lack of treatment of inappropriate care to this simple biomechanical dysfunction. The dysfunction is easily treated with the care cycle outlined if caught early, given effective treatment and prevented, the biomarkers affect the aging process.

How Common

10,000 -15,000 average steps per day 640 metric tons of stress on the joints

Even subtle faulty biomechanics can easily yield a chronic condition or predispose a patient to serious injury

How common are conditions related to faulty biomechanics of the lower extremities related

to simple foot pronation?

What are the long term effects to the aging process?

The abnormal strain effects the entire kinematic chain effecting all muscles, tendons, ligaments and joints.

Tonic/chronic protective spasm, pain and arthritis

Inactivity due to pain Chronic fatigue Depression “I’m just getting old”

Long term effects of faulty biomechanics of the lower extremities

Chronic Arthritis The most common cause of disability in the

elderly 43 million cases in 1997

Heart Disease Genetic Factors Diet Lack of proper exercise

Simple Foot Pronation

One of the most common examples of faulty biomechanics of the lower extremities is simple foot pronation

Simple Foot pronation causescollapse of the kinematic chain

Pronation of the foot causes a collapse of the kinematic chain causing pain, arthritic changes in multiple joints in the kinematic chain leading to inactivity, fatigue and possible depression. When the foot pronation becomes chronic this condition can lead to chronic fatigue and subsequent heart conditions due to inactivity.

The leading cause ofsimple foot pronation is...

Lower Extremity Anatomy Review

Mid Tarsal Joint Axis

The mid tarsal joint has 2 axis which function as a unit to allow for triplanar motion around these 2 axis

Mid Tarsal Joint Axis

Oblique Mid Tarsal Joint Axis– Primary Motions– Dorsiflexion Plantarflexion– Abduction Adduction

Longitudinal Midtarsal Joint Axis– Primary Motions– Pure inversion and eversion

Foot pronation occurs at the mid tarsal joint axis

Midtarsal pronation is limited when the cuboid comes in contact with the calcaneus

As long as the calcaneus is not in a valgus position

If the calcaneus is in a valgus position then the entire complex will collapse

Key to our Treatment Program

Maintaining the calcaneous in the neutral position is one of the key points to our treatment program. This demands excellent footwear selection with motion control. Use shoes with strong counters both for treatment and prevention purposes

Ligaments that Restrict Foot Pronation

Mid tarsal pronation is restricted by various restraining ligaments of the foot– Ligaments (See Figure)

Long and short Plantar Ligaments

Calcaneonavicular Ligament Bifurcate Ligament

Key to our treatment program

If these ligaments are damaged or chronically stressed they will not assist in limiting pronation. We manipulate the bones of the foot and work on the intrinsic muscles of the foot to increase the natural strength of the arch.– Midtarsal pronation is further limited in excessive

pronation in various stages of the gait cycle by the pronation/supinator cuff muscles

Key to our treatment program

Similar to the premise of treatment of rotator cuff musculature, we find that treatment of tonic protective spastic activity in Phase I and active strengthening of these muscles in Phase II, III and IV is a key component of our treatment program

Calf Muscles

Primary Movers Tibialis anterior– Soleus– Gastrocnemius

Pronator/Supinator Cuff

These muscles can act to prevent excessive pronation and supination of the foot (analogous to the rotator cuff muscles of the shoulder)

Pronator/Supinator Cuff Treatment

Phase I - Passive Treatment: Reduce weakness via deep

tissue work or EMS– Abductor Hallucis– Flexor Hallucis Brevis– Flexor Digitorum

Phase II, III, and IV - Active

Strength Training

– Abductor Hallucis– Flexor Hallucis– Flexor Digitorum Brevis

Pronation, treatment and prevention takes place when supination is aided by reduced weakness and increased strength of the extrinsic supinators of the foot (AKA supinator Cuff Muscles)

Pronator Supinator Chronic Weakness

With chronic pronator supinator cuff weakness the body shifts the weight to other muscles and serious injuries can occur

Calf Training

Training/Rehab demands joint motion in flexion extension be along the metatarsal joint axis

Phase I - Passive Treatment

Phase II, III and IV - Active

Strength Training Reduce weakness via deep

tissue work or EMS– Flexor Hallucis Longus– Flexor Digitorum Longus– Tibialis Posterior

Treatment of the Faulty Biomechanics of the Lower Extremity Related to Simple

Foot Pronation

Pronation Treatment/Training/Rehab Tip

Stretch these muscles– Extensor Hallucis Longus

– Extensor Longus & Brevis

– Tibialis Anterior

During the push off phase of gait, pronation is reduced when the peroneus longus is strengthened to insure that toe off will occur with a stable first, second and third digit. Joint motion is lost and must be regained through manipulation of the joints of the foot.

Improve toe off and Stride Length “Windlass Effect”

Excessive pronation is reduced with the “Windlass Effect”. When the toes dorsiflex, the heel lift draws the plantar fascia around the metatarsal heads which acts to pull the pillars of the longitudinal arch together thus decreasing the fore foot rear foot distance or strengthening the arch. This only happens when the patient steps off with reasonable toe off force.

Pronation CorrectionPhase I - Passive Treatment - Reduce weakness via deep tissue

work or EMS (See Figures)

Peroneus longus

Phase II, III and IV - Active Strength Training (See Figures)

Peroneus Training Tip

Reduce Tibial Torsion

Increase stride length to reduce tibial torsion

The sub talar joint acts as a directional torque transmitter converter frontal plane motion of the calcaneus into axial rotation torque or torsion of the tibia/fibula (shank). This can cause considerable internal rotational stresses on the tibia, femur and thus hip and lower back. When in the swing phase the opposite side, when swinging a reasonable distance or a longer stride which causes the effected side to reduce in torsion.

Treatment of the Knee Disorders Related to Simple Pronation of the foot

Conditions– Knee Instability– Peri-patellar Pain Syndrome - Patellofemoral arthralgia– Infrapatellar Cartilage Damage - Chondromalicia Patella

Phase I - Passive TreatmentReduce weakness via deep tissue work or EMS

Tensor Fascia Latae Biceps Femoris

(See Figure) (See Figure)

Strength training tip to reduce tibial torsion

Tibial Torsion Treatment and Prevention takes place when Reduced Torsion is aided by reduced weakness and increased strength of the Tensor Fascia Latae and the Biceps Femoris of the thigh. (See Figure)

•Knee extensions - the quad group pull the patella in the correct alignment

•Knee Flexion Bicep femoris pulls the shank back into proper alignment

•Hamstring Curls

Phase I Reduced Weakness - Deep Tissue or EMS (See Figure)

– Tensor Fascia Latae– Gluteus Maximus– Gluteus Medius– Gluteus Minimus

of the foot

Treatment of Lower Back Disorders or Syndromes

Non Traumatic Lower Back Pain Disorders or Syndromes Hyperlordosis Facet Syndrome

Traumatic Lower Back

Disorders and Syndromes Herniated Discs etc

We feel that a majority of these injuries are due to a prior predispositionfrom abnormal lower extremity biomechanics causing an anterior tilted pelvis and weight shift from the gluts and lateral thigh to the hamstrings and lower back causing overload and injury

Passive Phase I - Reduced Weakness of these muscles via deep tissue work or EMS

Hip External Rotators (See Figure)

Gluteus Medius Lumbar Extensors
