The following is based on an inspiring account, being circulated in Facebook.
A person by the name Chuah Chong Yi, had suffered a back injury in 2001 during rock climbing where he fell 2m flat on his back. In 2009, his left knee developed neurological spasm which would wake him up.
He saw a video in Mandarin that was shared in Facebook which was supposed to bring relief to backpain and spinal relief discomfort. He tried these exercises himself and found that they relief his back soreness and knee pain. Hence, the transcribed the video instructions in English hoping it will benefit more people.
The transcript is in this link: https://www.facebook.com/#!/photo.php?v=10151366002330518

Too many good sharing in FB gets buried in archives and gets lost amidst updates. I wanted to link it in my blog here so that I could refer back to it later.
