Manual therapy, or manipulative therapy, is a physical treatment primarily used by physical therapists, physiotherapists to treat musculoskeletal pain and disability; it mostly includes kneading and manipulation of muscles, joint mobilization and joint manipulation. It's also used by occupational therapists, chiropractors, massage therapists, athletic trainers, osteopaths, and physicians A 2011 literature review indicates that placebo is one of likely many potentially relevant mechanisms through which manual therapy improves clinical outcomes related to musculoskeletal pain conditions.
Definitions
Irvin Korr, J. S. Denslow and colleagues did the original body of research on manual therapy. Korr described it as the "Application of an accurately determined and specifically directed manual force to the body, in order to improve mobility in areas that are restricted; in joints, in connective tissues or in skeletal muscles." According to the Orthopaedic Manual Physical Therapy Description of Advanced Specialty Practice manual therapy is defined as a clinical approach utilizing specific hands-on techniques, including but not limited to manipulation/mobilization, used by the physical therapist to diagnose and treat soft tissues and joint structures for the purpose of modulating pain; increasing range of motion ; reducing or eliminating soft tissue inflammation; inducing relaxation; improving contractile and non-contractile tissue repair, extensibility, and/or stability; facilitating movement; and improving function. A consensus study of US chiropractors defined manual therapy as "Procedures by which the hands directly contact the body to treat the articulations and/or soft tissues."
Myofascial Therapy targets the muscle and fascial systems, promotes flexibility and mobility of the body's connective tissues. It is said to mobilize adhesions and reduce severity/sensitivity of scarring. A critical analysis finds that the relevance of fascia to therapy doubtful.
Massage may be used as part of a treatment. Proponents claim this may reduce inflammation. Science writer Paul Ingraham notes that there is no evidence to support the claim.
Friction massage is said to increase mobilization of adhesions between fascial layers, muscles, compartments and other soft tissues. They are thought to create an inflammatory response and instigate focus to injured areas. A 2012 systematic review found that no additional benefit was incurred from the inclusion of deep tissue friction massage in a therapeutic regimen, although the conclusions were limited by the small sample sizes in available randomized clinical trials.
Soft Tissue Technique is firm, direct pressure to relax hypertonic muscles and stretch tight fascial structures. A 2015 review concluded that the Technique is ineffective for lower back pain, and the quality of research testing its effectiveness is poor.
Trigger Point techniques claim to address Myofascial Trigger points, though the explanation of how this works is controversial
Stretching
From the main article's effectiveness section:
Apart from before running, stretching does not appear to reduce risk of injury during exercise.
Some evidence shows that pre-exercise stretching may increase range of movement.
The Mayo Clinic advises against bouncing, and to hold for thirty seconds. They suggest warming up before stretching or stretching post-exercise.
Taping
Manual therapy practitioners often use therapeutic taping to relieve pressure on injured soft tissue, alter muscle firing patterns or prevent re-injury. Some techniques are designed to enhance lymphatic fluid exchange. After a soft tissue injury to muscles or tendons from sports activities, over exertion or repetitive strain injury swelling may impede blood flow to the area and slow healing. Elastic taping methods may relieve pressure from swollen tissue and enhance circulation to the injured area. According to the medical and skeptical community there is no known benefit from this technique and it is a pseudoscience.
