Many people suffer from Foot pain or Knee pain when jogging, walking or running that causes them to stop such activities. If there is no injury that has caused injury to the foot or knee then the common question asked is what is causing my pain? One answer is that the problem can be caused by an excessive pronation of your foot. Pronation of the foot naturally occurs when the heel rolls inwards once the heel strikes the ground when walking or running. Excessive or abnormal pronation occurs when the foot rolls inwards for too long a duration. This leads to instability and fatigue within the joints of the foot eventually causing overuse injuries such as the following conditions;
Heel Pain such as a) Achilles tendonitis, b) Plantar Fasciitis,
Foot pain – c) Stress Fracture of 2nd metatarsal bone of foot, d) Bunions due to excessive mobility of the 1st metatarsal of the big toe, e) Callus formation under the 2nd metatarsal of 2nd toe
Excessive Foot Pronation is caused by abnormal structural deformities of the foot such as inward or outward angulations of foot structure when weight-bearing. In addition tight calf muscles which restrict the foot bending upwards (dorsiflexion) leads to over-pronation to compensate for limited dorsiflexion.
Signs of Excessive Pronation Foot
Erosion of sole of the shoe underneath the 2 metatarsal which adjoins 2nd toe.
Prominent bulging of the Talus head bone on inside of ankle
Flattening of inside (medial) foot arch when standing
Excessive internal rotation of the tibia bone when walking / running
Ankle joint bows inwards when standing
Treatment & Management of Excessive Pronation
I commonly meet patients in my clinic whose foot or knee pain is caused by excessive foot pronation. To treat this biomechanical abnormality the following elements would need to be addressed:
Wearing of straight shoe type instead of a curved type shoe.
Strengthening of Posterior & Anterior Tibial muscles of the foot.
Stretching of the tight Calf muscles
In some cases insertion of wedges to elevate medial arch or a custom made orthotic is incorporated.
