Ankle Pronation

DEFINITION

A condition in which the normal range of motion of the shock absorbing pronatory muscles and heel strike is exceeded.

 

MECHANISM OF INJURY

Developmental overuse ankle instability with lengthening of postural connective tissue (ligament, tendon, muscle). May be a genetic deformity.

 

SYMPTOMS

• Knee pain.
• Arch pain.
• Backache pain.

 

SIGNS

• Longitudinal and transverse arch loss and flattening.
• Lateral deviation of the Archilles tendon during weightbearing (walking - maximum 12 degrees eversion of calcaneus; running - maximum 16 degrees    eversion)
• Superior first and fifth metatarsal malposition.
• Inferior second, third, and fourth metatarsal malposition.
• Inferior tarsal malposition. 

TREATMENT

• Manipulation of involved biomechanical subluxations.
• Exercises to strengthen ankle, knee, and hip.
• FirmFlex Plus orthotics.

 

THERAPEUTIC EXERCISES

            Ankle Series Excercises.

PREVENTATIVE MEASURES

1. Gait monitoring and correction.
2. Control abnormal pronation with FirmFlex Plus orthotics.
