Flip-flops Can Alter Your Gait


Possible Cause of Painful Conditions


Flip-flops are a huge part of the summer scene. While they may be stylish and initially comfortable, flip-flops may actually cause problems for your feet, ankles, knees, hips, and back. How could a little pair of shoes do so much harm?

Impact of Flip-flops on Gait and Body Mechanics

Researchers from Auburn University studied how people walk in thong-style flip-flops. They found that people change how they walk in flip-flops compared to athletic shoes. The altered gait can cause problems for the flip-flop wearer -- especially if flip-flops are worn exclusively.
The researchers had study participants wear flip-flops and later wear athletic shoes to walk a platform that measured vertical force as their feet hit the ground. A camcorder also recorded stride length and limb angles.
Researchers found that when study participants wore flip-flops, they took shorter steps and their heels hit the ground with less vertical force than when they wore athletic shoes. The flip-flop wearers also did not bring their toes up quite as much during the leg's swing phase, creating a larger ankle angle and shorter stride length. Researchers felt this last observation was due to the wearers gripping the flip-flops with their toes.

Wear Flip-flops Occasionally

The flip-flops in the study were from well-known companies and priced in the $5 to 50 range. While researchers concluded that flip-flops change body mechanics and can lead to painful conditions, they did not forbid them. Recognizing that flip-flops are popular, their best advice was to limit their use: Wear flip-flops for short periods of time, but not as all-day footwear, and replace them every 3 or 4 months.

Sever's Disease in Adolescents


Sever's Disease

DISEASE INFORMATION

OverviewContact Us

Overview

Physicians at Advanced Foot & Ankle Center have experience caring for adolescents Sever’s disease, a common heel injury that can be easily treated without your child needing surgery.
What is Sever’s disease?
Sever’s disease (also known as calcaneal apophysitis) is a type of bone injury in which the growth plate in the lower back of the heel, where the Achilles tendon (the heel cord that attaches to the growth plate) attaches, becomes inflamed and causes pain.  Sever’s disease is the most common cause of heel pain in children, especially those who exercise or play sports on a regular basis.

Causes

What causes Sever’s disease?
The heel bone grows faster than the ligaments in the leg. As a result, muscles and tendons can become very tight and overstretched in children who are going through growth spurts. The heel is especially susceptible to injury since the foot is one of the first parts of the body to grow to full size and the heel area is not very flexible. Sever’s disease occurs as a result of repetitive stress on the Achilles tendon. Over time, this constant pressure on the already tight heel cord can damage the growth plate, causing pain and inflammation.
Such stress and pressure can result from:
  • Sports that involve running and jumping on hard surfaces (track, basketball and gymnastics).
  • Standing too long, which puts constant pressure on the heel.
  • Poor-fitting shoes that don’t provide enough support or padding for the feet.
  • Overuse or exercising too much can also cause Sever’s disease.
Who gets Sever’s disease?
Sever’s disease is most likely to occur during the growth spurt that occurs in adolescence. For girls, growth spurts usually occurs between 8 and 13 years of age. For boys, it’s typically between 10 and 15 years of age.
The back of the heel hardens and becomes stronger when it finishes growing, which is why Sever’s rarely occurs in older adolescents and teenagers.

Symptoms

What are the symptoms of Sever’s disease?
The most common symptoms of Sever’s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. 
A child with Sever’s may also have these common problems:
  • Heel pain with limping, especially after running.
  • Difficulty walking
  • Discomfort or stiffness in the feet upon awaking
  • Swelling and redness in the heel
Symptoms are usually worse during or after activity and get better with rest.

Diagnosis

How is Sever’s disease diagnosed?
Sever’s disease can be diagnosed based on the symptoms your child has. Your child’s doctor will conduct a physical examination by squeezing different parts of your child’s foot to see if they cause any pain.
An X-ray may be used to rule out other problems, such as  a broken bone or fracture.

Treatment

The primary method of treating Sever’s disease is taking time off from sports and other physical activities to alleviate the pressure on the heel bone.
During the healing period, your child’s doctor may also recommend:
  • Physical therapy or any type of exercise that involves stretching and strengthen leg muscles and tendons.
  • Wrapping ice in a towel and placing it under the child’s heel will also help to alleviate and reduce pain and swelling.
