Strengthening Exercise for Torticollis

With my daughter's right torticollis, the right side neck muscles are tighter and stronger than the left side.  In addition to stretching the right side of her neck, we also do exercises to strengthen her left side. Both types of exercises are important in helping to lessen her torticollis.  The exercise below works to strengthen her weak, left side neck muscles by forcing her to work against gravity.  I have included a brief video tutorial AND written instructions in the space below.

Kellyn's Progress in Physical Therapy

So Kellyn has been in physical therapy now for about three weeks.  Overall, I think she is making good progress.  I have noticed that her right head tilt is not as pronounced as it previously was.  Also when I tilt her to her right, she is now able to pick her head up much easier than she used to.  So her neck muscles have definitely strengthened.  Her trunk is much less inclined to tilt to the left now too.  I think the lessening of her trunk tilt is a more dramatic improvement compared to her the decrease in her head tilt.
