Thai massage has a wide range of benefits. Here are some benefits for how it will impact your muscle. Some joint pain is caused by tight (shortened) muscles which pull on the joint, causing pressure and sometimes misalignment of the joint. The combination of gentle massage and stretches in Thai massage relaxes and lengthens tight muscles. This takes pressure off the joints and allows them to fall back into proper alignment, relieving the pain. Additionally, the muscular flexibility gained in a Thai massage allows for greater range of motion in the joints.
