From Richard Hind, York, UK
The article “Your second skin” provides a very insightful overview of current research into fascia tissue (14 May, p 38). I was intrigued by the suggestion that it could be classified as a sensory organ.
Anyone who has practised tai chi or qigong for a number of years may have experienced this as the feeling of “qi flowing” – any sensation from a slight tingle to a deep ache – during stretching and movement. I have used these methods to tame upper-back muscle spasms, which lasted a week or two when I was in my 20s. I am now over 50 and, at worst, I am uncomfortable for a day or two after a flare-up.
I hope researchers investigate these ancient practices to evaluate their effectiveness in moving and stretching fascia tissue.
