I know this sounds like an odd combination of injuries to be
discussing at the same time; but it is not uncommon to see a patient that has a
weak posterior tibial muscle, and subsequent posterior tibial tendonitis that
causes IT band syndrome in the same leg due to excessive pronation and
dorsiflexion causing stress on the IT band at the knee level. It is also not
uncommon to see a runner with a weak and tight IT band that allows increased
inward movement of their thigh which causes increased pronation at the ankle,
stressing the posterior tibial tendon leading to tendonitis.
So how can we control this unpleasant duo injury? Control
the pronation of the foot and ankle with a functional foot orthotic device or
taping, strengthen the posterior tibial muscle in your lower leg, stretch the
IT band, and work on core balance exercises.
Here are some simple exercises to get you started:
First and foremost, warm up for about 5-7 min with a bike,
elliptical or simply brisk walking.
All exercises will strengthen your dorsiflexion and
inversion power as well as working on single leg balance.
1.
Walk on your heels with your ankle pointed
upward and toes outward exaggerating the movement. It looks quite silly but it
fatigues the PT muscle rapidly. A “normal” runner should be able to walk this
way for about 2 minutes without aching pain. If you start with 30 sec at a time
and then repeat 3 times to start. The next time add 15 sec and so on until you
can perform this motion for 2 minutes. If you feel any sharp pain, then stop
and try again in a few days.
2.
Eccentric knee squats. The goal is to perform 4
of these. Stand facing a wall with your feet should width apart and your toes a
few inches from the wall. Bend at the knees keeping your back straight so that
your knees lightly touch the wall. You may need to adjust the distance to the
wall to perform this. Return to your starting position and start to squat
again, but move your knees outward so that you are effectively pronating your
feet as you squat point. This is the action your feet perform in the stance
phase of running. It puts a force on the PT muscle and the IT band. This
strengthens the tendon as well as the IT band. Come back to the starting
position and repeat four times. If at any point you have sharp pain, stop. It
will take a few days to weeks to perform these easily. When this happens, try
one leg at a time.
3.
Balance and eccentric reaches with your knees.
Stand on your right foot, about an arm’s-length from a wall and flex your left
knee so that your shin is about parallel to the floor. Bring your left knee
forward, while remaining with your back straight or slightly backward from the
hips, until it touches the wall. Keep your hips over the right foot. Finish by
returning to the starting position. Next, perform the same motion but this time
move your knee slightly to the left as you move it forward. This will cause the
right foot to pronate. Then back to the starting position and do the same
movement moving your knee this time to the right. This will cause the right
foot to supinate. Perform this 5 times then switch feet.
4.
Dynamic Posterior tibial exercises. Begin by
facing the wall again. With your weight on your right foot and your right knee
slightly flexed (like you are landing while running), lift your left thigh up
parallel with the floor and use your hands on the wall for support. Rock
forward until you feel a calf stretch, then lean left and pronate your right
foot. Then, as part of a continuous motion, lean toward the right, crossing
your left leg over your right leg so that now your foot is supinated. Without
stopping, cycle back and forth 4 times then shift to the left foot.
5.
Towel crunches. Sitting in a chair, place your
foot flat on a towel and crunch your toes grasping at the towel for 25
repetitions. Then switch feet.
When you are
comfortable going through all of these exercises with your body weight, then
start adding small hand weights to increase your strength. You should perform
these simple exercises before you run at least 3 times a week to become a
stronger more efficient runner!
Let’s try to avoid the duo of PT tendonitis and
IT band syndrome!
