Definition: An orthopedic appliance or apparatus used to support, align, prevent, or correct deformities or to improve the function of movable parts of the body.

Also Known As: braces, splints

Examples:

  • AFO - Ankle Foot Orthosis; orthotic device for the lower limb that encloses the ankle and foot and does not extend above the knee. This is commonly used in foot drop where weakness of the anterior tibialis prevents you from lifting your foot and toes up off the floor.
  • Cervical - a rigid plastic orthosis that encircles the neck and supports the chin and the back of the head.
  • KAFO - Knee Ankle Foot Orthosis; orthotic device for the lower limb that extends from above the knee to the ankle and foot.
  • LSO - Lumbosacral Orthosis; spinal orthosis that encircles the body in the lumbosacral region. This is often used after spinal surgery or to treat low back pain from spinal stenosis.

Orthotics may be recommended by your physical therapist to help align your body or to help support a joint or joints. This can improve your overall functional mobility.

One of the most common areas that people use orthotics is in their shoes. If your feet are pronated in and are flat, this can lead to several problems. These may include:

  • Plantar fasciitis
  • Achilles tendonitis
  • Peroneal tendonitis
  • Posterior tibial tendonitis
  • Knee pain

If you foot turns in too much, it may place stress on your lower extremities, leading to pain and difficulty walking or moving around properly.

Sometimes, weakness in your hip muscles go hand in hand with foot pronation.

Orthotics in your shoes help to gently lift up your foot's arch, placing your foot and lower leg in an optical position. When your foot is over-pronated, your lower leg internally rotates inwards, leading to stress and strain on your knees.

Correction with orthotics can help with a host of problems in your lower extremities.

A knee brace may also be considered an orthotic. After surgery, like an ACL reconstruction, your doctor may want to stabilize your knee joint while it is healing. You may be required to wear a knee brace as an orthotic to help keep everything in the right place while things are healing. Your physical therapist can show you how to properly wear your knee brace after surgery and ensure that it is not too tight or too loose.

If you are having pain or any sort of fuctional mobility limitation, your physical therapist may use an orthotic to help correct your condition. Check in with your doctor, and then visit your physical therapist to see if you would benefit from using an orthotic to correct your condition.
