Learn about the exercises your child can perform to help minimize swelling and maintain their range of motion and muscle strength after limb lengthening and reconstruction with a tibial frame.

Key points

  • It is important to keep your child's leg elevated above their heart when resting and for them to perform regular ankle pumps and circles to manage edema.
  • It is very important to ensure your child performs range of motion exercises to help maintain movement in their joints and prevent stiffness.

Following surgery, your child will experience some edema (swelling) and stiffness. Regular exercises will help your child minimize swelling and maintain range of motion and muscle strength.

Managing edema

It is important to keep the leg elevated above the heart when resting and to perform regular ankle pumps and circles.

Ankle pump and circles

Starting position: Sitting on a bed or a chair with leg extended straight

  1. Move the ankle to bring the toes and foot towards the face.
  2. Move the foot back down like it is pushing on a gas pedal.
  3. Move the ankle in circles in both directions. It might help to imagine drawing a circle with the big toe.

Do _____ pumps and circles (each direction) every hour or if your child is sitting for a long time.

Ankle pumps (1)
(2)
Ankle circles

Range of motion exercises

Range of motion exercises help maintain movement in your child’s joints throughout your child’s leg lengthening process. It is very important to do them to prevent joint stiffness and any related complications.

Notes about the exercises

  • Not all the exercises shown here may be necessary for your child. If your child’s foot is bound to their frame, ankle exercises will not apply to them. Your child’s physiotherapist will explain which exercises your child should do and how to modify them if needed.
  • Some exercises require you to handle your child’s leg to further a stretch or support the weight of their frame. Depending on the location of your child’s frame and pin sites, your handling may vary a little from the descriptions below. Your child’s physiotherapist will assist you with this.
  • As a general rule, try to place your hands as close as possible to the joint you are stretching to avoid added stress through the bone.
  • Your child should do the recommended exercises three times a day or as often as instructed by the physiotherapist.

Ankle dorsiflexion (DF) while sitting

Ankle dorsiflexion while sitting

Starting position: Sitting on a bed with leg extended straight

Ankle plantar flexion

Ankle plantar flexion

Starting position: Sitting or lying down

  1. Slowly move the toes downwards like the foot is pushing on a gas pedal. Your child should feel the stretch on the front of the ankle.
  2. If they do not feel the stretch, you can help by bringing the ankle further into the movement. You should put one hand over the top of the foot and another hand just above the ankle if the frame allows.
  3. Hold for ____ seconds.

Do exercise ____ times. Repeat _____ times a day.

Ankle inversion and eversion

Starting position: Sitting or lying down

  1. For inversion, bring the big toe in towards the midline.
  2. For eversion, move the baby toe away from the midline.
  3. Make sure only the foot and ankle are moving. Keep the rest of the leg still. It might help to imagine that the foot is moving like a windshield wiper.

Do ____ inversions and eversions. Repeat _____ times a day.

*Note: If your child’s ankle gets tight, you may be asked to help them stretch it further towards or away from the midline. Your therapist will help with this.

Ankle inversion
Ankle eversion

Toe flexor stretch

Starting position: Sitting or lying down

Warm-up: Wiggle the toes up and down approximately 10 times to warm up the muscles

  1. Holding your child’s big toe (as shown below), gently bring it towards the face until a stretch is felt along the bottom of the foot.
  2. Hold for ____ seconds.
  3. Repeat steps 1 to 2 with the remaining toes together.

Do exercise _______ times. Repeat ____ times a day.

*Note: Sometimes the wires near the toe will block full extension, so just move it as far into extension as the frame allows.

Big toe stretch
Toe flexor stretch

Knee flexion and extension (active assisted)

Starting position: Lying down on a bed or other smooth surface (to allow the heel to slide)

Warm-up: Slowly bend and straighten the knee 10 times as much as possible in each direction

  1. For flexion, bend the knee and slowly slide the heel up towards the bum, as far as it can go. If the heel cannot touch the bed because of the frame, you can support your child’s leg and help them move it to make sure that they have a full range of motion.
  2. When your child feels a stretch over the front of their thigh, hold the position for five seconds.
  3. For extension, slowly move the heel back down the bed until the leg is straight again.

Do exercise ____ times. Repeat ____ times a day.

*Note: Some children may require the adult assisting them to perform most of the movement. This will be determined by your child’s physiotherapist.

Knee flexion
Knee extension

Knee flexion (assisted)

Assisted knee flexion

Starting position: Sitting at the edge of a chair or bed so the frame is off the surface

  1. Straighten the knee. You should help by holding your child’s lower leg to support the weight of the frame.
  2. Slowly bend the knee. You should let your child bend their knee by themselves. Use one hand to support the frame as it lowers and use the other hand to support the knee.
  3. Keep bending the knee until your child feels a stretch in the font of their thigh or until the frame stops them from bending any further. You may need to have your child move forward on the bed to allow more room for the knee to bend.

Prone lying

Prone lying

Starting position: Lying on the stomach on a bed, with knees and lower leg off the edge of the bed

  1. Have your child lie like this for 15-20 minutes, making sure that the front of the hips stay flat on the bed. This keeps the pelvis level.
  2. If the frame is too heavy, you can support your child’s lower leg, or place a stool under it, making sure the knee can stay completely straight. The stool should be lower than the bed to ensure there is no bend in the knee.
  3. Perform this stretch once daily.

Assisted knee extension

Assisted knee extension

Starting position: Sitting

  1. Place one hand above your child’s knee and one hand around their lower leg, as close as possible to the knee to support the joint. Depending on the frame, you may use your full forearm to support the lower leg.
  2. Gently press downwards above the knee and upwards against the lower leg. This is to extend (straighten) the knee.
  3. Hold for ____ seconds.

Do exercise ___ times. Repeat ____ times a day.

*Note: Due to the shape of the frame, you will likely need to place a small roll under your child’s ankle/frame to allow for full extension of the knee during the stretch.

Knee extension stretch (standing)

Knee extension

Starting position: Standing with the leg extended straight on a stair or on the floor, depending on flexibility

  1. Have your child stand with their heel on the floor, or a block, and their toes against a wall.
