Beneficial Effects of Massage Therapy
Peer-reviewed medical research has shown that the benefits of massage include pain relief, reduced trait anxiety and depression, and temporarily reduced blood pressure, heart rate, and state anxiety. Theories behind what massage might do include blocking nociception (gate control theory), activating the parasympathetic nervous system which may stimulate the release of endorphins and serotonin, preventing fibrosis or scar tissue, increasing the flow of lymph, and improving sleep but such effects are yet to be supported by well designed clinical studies.
Single dose effects
Pain relief: Relief from pain due to musculoskeletal injuries and other causes is cited as a major benefit of massage. In one study, cancer patients self-reported symptomatic relief of pain.  Massage can also relieve tension headaches. Shiatsu, Acupressure or pressure point massage may be more beneficial than classic Swedish massage in relieving back pain.
State anxiety: Massage has been shown to reduce state anxiety, a transient measure of anxiety in a given situation. 
Blood pressure and heart rate: Massage has been shown to reduce blood pressure and heart rate as temporary effects. 
Attention: After massage, EEG patterns indicate enhanced performance and alertness on mathematical computations, with the effects perhaps being mediated by decreased stress hormones.
Other: Massage also stimulates the immune system by increasing peripheral blood lymphocytes (PBLs).
Multiple dose effects
Pain relief: When combined with education and exercises, massage might help sub-acute, chronic, non-specific low back pain.  Furthermore, massage has been shown to reduce pain experienced in the days or weeks after treatment. 
Trait anxiety: Massage has been shown to reduce trait anxiety; a person's general susceptibility to anxiety. 
Depression: Massage has been shown to reduce subclinical depression. 
Diseases: Massage, involving stretching, has been shown to help with spastic diplegia resulting from Cerebral palsy in a small pilot study.
