Thai Massage is an ancient healing modality with origins in Ayurvedic Medicine and Yoga . It has evolved into a unique and deeply healing combination of deep stretching of the fascia, muscles and joints, rhythmic compression, soft-tissue release,  rocking, and acupressure. It is done fully clothed, and on a comfortable mat. It is best to wear comfortable clothing that allows for full range of motion. Here is a link to a study showing thai massage is even more effective than physical therapy for decreasing muscle spasticity (tension). http://www.massagetoday.com/mpacms/mt/article.php?id=15059
