Plantar Fasciitis
The plantar fascia is a dense band of fibrous tissue that extends
from the bottom of the heel bone (calcaneus) to the base of the toes
(ball of the foot). It is the primary supporting mechanism for the arch
of the foot. It is attached to the middle region of the calcaneus, and
as it progresses toward the forefoot it divides into 5 sections, each
extending into a toe and straddling the flexor tendons. Plantar
fasciitis is inflammation of the plantar fascia.
Plantar fasciitis is often associated with heel
spurs, which are protrusions that develop along the edge of
calcaneous. The term “heel spur” is often used interchangeably with the
term “plantar fasciitis;” but the conditions, while closely related,
are not identical. Heel spurs typically are not painful and can occur
without plantar fasciitis; but their intrusion into the soft tissue
surrounding the area (the plantar fascia) can be a source of irritation
to the tissue and a contributing cause of heel pain. Heel spurs often
occur as the body’s response to inflammation of the plantar fascia.
Pain from plantar fasciitis can best be described as a stabbing or
burning pain, akin to a hot nail being driven into the inside area of
the heel. It is often most noticeable in the morning when you arise
from sleep. Because the plantar fascia has been relaxed and has
contracted during the night while the foot is plantar flexed (pointed
downward in a heels up position), pointing the toes upward (called
“dorsiflexion”) causes the fascia to stretch and become irritated again,
producing the morning pain that is typical of plantar fasciitis. Pain
from plantar fasciitis often diminishes once you have been walking or
exercising for a while.
| Cause |
Plantar fasciitis is most often caused by…
- Overuse or a sudden rapid increase in physical activity.
Plantar fasciitis is common in long-distance runners. Running, walking
or stair climbing also can place too much stress on the heel area.
Other types of sudden exertion such as lifting heavy weights can trigger
the pain.
- Faulty biomechanics. Overpronation (flat-footedness), a
high arch or having an abnormal gait pattern can adversely affect the
way weight is distributed when you're on your feet, putting abnormal
amounts of stress on the plantar fascia.
- Being overweight, especially if weight gain takes place
rapidly.
- Poorly designed shoes. Shoes that are thin-soled, too
loose, too stiff, or that lack arch support and impact absorption don't
protect the feet well. If you regularly wear shoes with high heels, the
Achilles tendon can contract and shorten, causing strain on the plantar
fascia.
- Arthritis. Some types of arthritis can cause
inflammation in the tendons in the bottom of the foot, which can lead to
plantar fasciitis.
- Diabetes. The exact relationship is unknown; but plantar
fasciitis occurs more often in people with diabetes than in
non-diabetic people.
- Being on the feet for extended periods. People in
occupations that require a lot of walking or standing on hard surfaces,
including factory workers, teachers and waitresses, often develop
plantar fasciitis.
Plantar fasciitis is typically treated with the least
invasive techniques being tried first. The first remedy is to cut back
on intensity and duration of physical activity and time spent on one’s
feet. Elevating the heel slightly with inserts is a typical first
approach, and may be incorporated with other non-invasive techniques
such as icing and stretching. Ant-inflammatory drugs are often
prescribed, as are a variety of therapy techniques that involve
maintaining the foot in a dorsiflexed position at night during sleep and
the use of corrective orthotics. In plantar fasciitis the most
critical necessity is proper arch support; and most foot specialists
recommend that patients not go barefooted.

| Prevention |
- The Integrated Comfort Solution (consisting of Thorlos
engineered padded socks, an insert
or orthotic as necessary, and properly designed and fitted shoes or
boots) helps provide the
protection you need to help prevent plantar fasciitis. In situations
where plantar fasciitis is already present, it also helps diminish pain
by protecting the heel from shock and impact.
- The Thorlos engineered padded sock component of the Integrated
Product Solution provides anatomically designed terry padding that
cushions impacts and protects vulnerable areas from pressure and bumps.
It helps ensure heel coupling and proper interface with the arch area
to provide correct postural alignment that promotes proper biomechanics.
- Inserts that provide arch support and a slight heel
lift help ensure that not too much stress is placed on the plantar
fascia to reduce the possibility of inflammation and overstretching. In
cases of overpronation (read more), inserts help support and keep the feet
from turning in excessively. They also help support the arch area and
promote proper biomechanics.
- Properly designed and fitted shoes or boots provide
sufficient cushioning and flexibility in the soles, helping to diminish
the possibility of the irritation and inflammation that can lead to
plantar fasciitis.
- If you are an overpronator, have your gait analyzed by a
foot care professional and get the right orthotics as a component of an
integrated solution to help address the overpronation.
- If you feel a burning sensation in the heel area that
signifies the possible onset of plantar fasciitis, see a foot care
physician before the pain becomes too bad.

| Medical Issues |
- While plantar fasciitis is often a painful and even
debilitating condition, it typically is curable and will not do any long
term damage; however, the pain from plantar fasciitis can lead to an
inability to perform certain work, and can limit participation in
physical activities and sports.
- Recovery from plantar fasciitis may take up to 6 to 9
months; and in some cases, anti-inflammatory injections or surgery are
the only successful treatments.
- A relatively recent and fairly successful treatment method
for particularly difficult cases is extracorporeal shock wave therapy
(ESWT) (read more).
Remember, ALWAYS consult your physician if you have
pain in any area of your feet that persists for more than a few days. |
