Stand up straight with a towel or band around your upper back.
Position the band around your affected area and hold the ends in each hand.
To improve your rotation towards the right, pull forwards with your left hand, keeping some gentle tension in the band.
Simultaneously turn your body towards the right.
Oscillate the movement, pulling with the band as you rotate, and easing gently off the band as you turn back a little.
Repeat this movement rhythmically.
