Standing quadriceps stretch
Have the patient flex one of their knees and grasp it at the ankle. Holding onto a wall for support, the patient should pull towards the buttocks until they feel a stretch in their quadriceps muscle. Have the patient perform the exercise on both legs. If any pain emerges the exercise should be stopped.
Exercise should be done two times each for both legs. Stretch should be held for seconds
Ideally the stretch should be performed everyday, but 3-4 times a week is suitable.
A rest of seconds should be done before going onto the second repetition for each leg.
This stretch allows for lengthening of the quadriceps muscle group. This is essential for the ACL because it allows for the quads to have a more stable support for the knee.

Hip-Twist Ankle Hop
Patient begins exercise with the feet shoulder width apart and knees bent to 90°. They will jump into the air, and turn 90° to the left (twisting at the hips). The patient will land and bend knees to 90°, then jump again from the same knee bend position, turning to face forwards. The motion is repeated to the right.
The exercise should be repeated 10 times to the left, and 10 to the right with a forward facing jump in between. One to two sets (depending on comfort level)
This activity should be done 3-5 times a week once the patient is comfortable enough for such an activity.
This is to be done once the patient has been through treatment and the range of motion has increased.
A rest of 2 to 3 minutes should be taken between sets
This exercise will be ideal for stabilization and strengthening of the knee joint (particularly the ACL, meniscus and collateral ligaments) because it involves landing and jumping quickly in a rotated position.

Lateral Jump to Box
The patient will lower their body into a semi-squat position and jump up onto box (which is to their side). They will be instructed to not hold a squat position before jumping up and keep the time between dipping down and jumping up to a minimum. The patient steps down from the box.
The exercise should be repeated 10 times to the left, and 10 to the right. One to two sets (depending on comfort level)
This activity should be done 3-5 times a week once the patient is comfortable enough for such an activity.
This is to be done once the patient has been through treatment and the range of motion has increased.
A rest of 2 to 3 minutes should be taken between sets
The exercise increases stability and strength within the knee, especially the lateral and medial collateral ligaments because it involves lateral jumping and landing with an incline.

Walking
The patient will be encouraged to work on walking without the use of crutches.
Starting with short distances (down a hallway) and building to longer distances (around a track).
Daily, building further distance with practice and as the joint allows.
Dependant on pain level.
Walking requires a range of motion of 0° extension to 60° flexion. Also, an average of 13° of tibial rotation is needed.
Due to the ranges of motion required for gait, weight bearing may be difficult for the patient at first. However with increased distances, the muscles surrounding the knee will become more stable, allowing the patient to return to normal activities sooner.

26. Functional Activity #2 Description Repetitions Frequency Rest
Exercise Mechanics
Stairs
Once the patient has been able to walk without the use of crutches, they should be able to advance to climbing and descending stairs.
The patient should begin with a small stair case (maximum of three). They should be able to ascend and descend these with minimal pain before moving to larger stair cases. Repeat daily as stairs are present during daily activities (ie school, work, home)
Daily, building further distance with practice and as the joint allows.
Dependant on pain level. (Use an elevator or crutches if needed)
Normal Range of Motion for the knee is from 0° of extension to 135° of flexion. The maximum knee flexion needed for this movement is between 83° and 105° to ascend and 86° to 107° to descend the stairs.
Many muscles surrounding the knee are engaged, including the hamstrings, quadriceps, collateral ligaments and meniscus.

Exercise Mechanics
Achilles Stretch
This exercise is to be performed as a prolonged stretch. The patients stands with the back to the wall. The feet are placed on the edge of a book with the heel no more than 2.5 cm from the wall. A towel roll is placed between the posterior knees and the wall to prevent knee hyperextension. The patient stands in this position for a prolonged period.
1 repetition. Stretch is held for at least 5 minutes and up to 20 minutes if tolerable.
Daily
Few hours to a days worth of rest.
This stretch applies tension to the Achilles tendon over a prolonged period and thus tension is experienced in the gastronemius and soleus muscles. Once the stretch is released, the patient commonly feels stiffness in the posterior calf or ankle area, but this should subside quickly. Common substitutions are standing with the feet in pronation, standing too far away from the wall, and hyperextension of the knees.

Gastrocnemius Stretch (sitting position)
With the patient sitting position, as stretch strap or towel is hooked around the forefoot. Keeping the knee straight, the patient pulls on the strap to dorsiflex the ankle. Additional stretch can be applied with active contraction of the ankle dorsiflexors.
3 repetitions each repetition is held for seconds.
Daily
Patient rests seconds in between repetitions.
Because the gastrocnemius extends from above the knee to the calcaneus, both the knee and ankle joints must be placed on stretch to effectively stretch the muscle. Common substitutions in this exercise are hip rotation and foot pronation.

Dorsiflexor Stretch
Beginning on hands and knees with dorsum of foot and anterior portion of lower legs flat on a mat. The patient. The patient leans forward on the hands and pushes the hips back toward the heels as tolerated.
3 repetitions each repetition is held for seconds.
Daily
Patient rests seconds in between repetitions.
Ankles lacking full plantar flexion can be stretched with the patient sitting on the heels. Once full range is achieved, he or she should be able to sit fully on the ankles. This stretch puts considerable tension on the knees and should not be performed if the patient has a history of knee problems. The main muscle under stretch in the lower extremity is the tibialis anterior.

34. Strength Exercise #1 Description Repetitions Frequency Rest
Exercise Mechanics
Rubber Tubing Dorsiflexion
The patient sits with the tubing around the forefoot and anchored to a table, which the patient faces. The patient pulls the foot toward the shin, dorsiflexing the foot. The foot is lowered to its original position and then brought through dorsiflexion once again.
10-15 repetitions
3-5 times per week.
30 seconds rest in between sets.
This exercise strengthens the ankle dorsiflexors, primarily the tibialis anterior. The most common substitution in this exercise is knee flexion.

36. Strength Exercise #2 Description Repetitions Frequency Rest
Exercise Mechanics
Rubber Tubing Plantar Flexion
The patient sits on a table in a long-sitting position with the tubing around the plantar foot and grasped in both hands. Maintaining a firm tension on the tubing and starting with the foot in full dorsiflexion, the patient pushes the foot against the tubing to move the ankle into plantar flexion. The ankle is returned to its original position and the movement is repeated.
10-15 repetitions
3-5 times per week.
30 seconds rest in between sets.
This exercise can be used to strengthen the plantar flexors of the ankle: gastrocnemeus, soleus, peroneus longus (to a lesser extent). This exercise is especially useful if the patient is non-weight bearing. This exercise can be modified to be performed with the knee in flexion and the patient sitting on a table with their extremity hanging off the table. In this position, plantar-flexion motion isolates and strengthens the soleus muscle.

Heel Raises
With the feet shoulder-width apart, the patient rises up on the toes as high as possible and then returns to a position with feet flat on the floor. This exercise can be performed on an incline or the edge of a stair to increase the difficulty.
10-15 repetitions
3-5 times per week.
30 seconds rest in between sets.
This exercise strengthens the posterior aspect of the lower leg, mainly the gastrocnemeus and the soleus. Common substitutions include using the hamstrings by flexing the knees during the heel raise, moving the body forward or rocking rather than moving straight upward, and placing most of the body weight on the uninvolved extremity rather than equally distributing the weight over both extremities.

Stork Stand
The patient stands on the involved extremity while attempting to maintain balance.
3 repetitions each held for 30 sec.
Daily
30 seconds rest between each set.
Posture and balance are important in maintaining ankle stability. Once this exercise is accomplished, the patient can perform the exercise with eyes closed to eliminate visual balance. The stork stand can also be performed on an unstable surface such as a trampoline or a foam roller.

Ankle Motion Exercise (Swiss Ball)
The patient stands in pelvic neutral with the uninjured foot on top of the ball. The patient then writes the alphabet with the uninjured foot, using the ball as a base off support.
3 repetitions
Daily
30 seconds rest in between each set
This is a balance exercise for the lower extremity. By using the uninjured foot to perform motion, the injured foot is forced to maintain balance and thus stability is the point of focus for the exercise. The patient should not feel any significant pain or discomfort, and repetitions can be adjusted to compensate for particular contraindications.

Exercise Mechanics
Bridging (Swiss Ball)
The patient is positioned supine on the ball so that the scapulae are on the ball and the feet are on the floor about shoulder-width apart. The pelvis is in neutral and the abdominals are tight as the patient lifts the buttocks and extends the hips. The movement is initiated at the buttocks, and the pelvis is kept in neutral throughout. Heels remain flat on the floor.
3 sets of 10 repetitions.
Daily
30 seconds rest in between sets
This exercise strengthens the back extensors and may assist in rehabilitating the patients lower back pain. Stability is referred to the ankles which are flat on the floor as well as the abdominals. The exercise is more challenging if the patient marches in place while maintaining pelvic neutral.

Skipping
The patient will begin skipping with a rope, using both feet and only jumping approximately 2 inches off the ground. They should be reminded to bend their knees to absorb the shock of landing. The pace of skipping can be determined by the patient, increasing as they get stronger.
The exercise can be repeated for about 2 minutes, depending on the patients comfort and pain levels. Two to three sets can be performed.
This activity should be done 3-5 times a week once the patient is comfortable enough for such an activity.
This is to be done once the patient has been through treatment and the range of motion has increased.
A rest of 2 to 3 minutes should be taken between sets.
This exercise involves short, quick bursts from many muscles, including the gastrocnemeius, soleus, plantaris and especially the Achilles Tendon. The exercise will help to strengthen and stabilize these structures while also increasing cardiovascular fitness.

Driving Simulation
The patient will sit on a chair with a spongy ball (or rolled up socks) under their toes on one foot. He is asked to push down on the ball as if he is driving a car.
If the injury is in the right ankle (or the patient drives a manual car), this exercise can be performed whenever they need to drive somewhere.
If they have injured their right foot, they can perform this activity while watching TV, eating dinner, at work, etc.
Daily, building further distance with practice and as the joint allows.
Dependant on pain level – whenever they are not in a car.
The normal range of plantar flexion is about 50’. Flattening the ball completely requires about 45’, and driving will need slightly more range.
