Plantar Fasciitis
Definition
Plantar Fasciitis is an inflammation caused by excessive stretching
of the plantar fascia. The plantar fascia is a broad band of
fibrous tissue which runs along the bottom surface of the foot,
attaching at the bottom of the heel bone and extending to the
forefoot. When the plantar fascia is excessively stretched, this
can cause plantar fasciitis, which can also lead to heel pain,
arch pain, and heel spurs.
Cause
Plantar Fasciitis often leads to heel pain, heel spurs, and/or
arch pain. The excessive stretching of the plantar fascia that
leads to the inflammation and discomfort can be caused by the
following:
- Over-pronation (flat feet) which results in the arch collapsing
upon weight bearing
- A foot with an unusually high arch
- A sudden increase in physical
activity
- Excessive weight on the foot, usually attributed to
obesity or pregnancy
- Improperly fitting footwear
Over-pronation (flat feet) is the leading cause of plantar fasciitis.
Over-pronation occurs in the walking process, when a person's
arch collapses upon weight bearing, causing the plantar fascia
to be stretched away from the heel bone.
With Plantar Fasciitis, the bottom of your foot usually hurts
near the inside of the foot where the heel and arch meet. The
pain is often acute either first thing in the morning or after
a long rest, because while resting the plantar fascia contracts
back to its original shape. As the day progresses and the plantar
fascia continues to be stretched, the pain often subsides.
Treatment and Prevention
The key for the proper treatment of plantar fasciitis is determining
what is causing the excessive stretching of the plantar fascia.
When the cause is over-pronation (flat feet), an orthotic with
rearfoot posting and longitudinal arch support is an effective
device to reduce the over-pronation and allow the condition to
heal.
If you have usually high arches, which can also lead to plantar
fasciitis, cushion the heel, absorb shock and wear proper footwear
that will accommodate and comfort the foot.
Other common treatments include stretching exercises, plantar
fasciitis night splints, wearing shoes that have a cushioned
heel to absorb shock, and elevating the heel with the use of
a heel cradle or heel cup. Heel cradles and heel cups provide
extra comfort, cushion the heel, and reduce the amount of shock
and shear forces placed during everyday activities.
Every time your foot strikes the ground, the plantar fascia
is stretched. You can reduce the strain and stress on the plantar
fascia by following these simple instructions: Avoid running
on hard or uneven ground, lose any excess weight, and wear shoes
and orthotics that support your arch to prevent over-stretching
of the plantar fascia.
If problem persists, consult your foot doctor.
