Pain can many times be a result of imbalances within the musculoskeletal system.
In a paper written by the American Council on Exercise in 2010, they state:
The entire musculoskeletal system is constantly working and/or compensating to remain balanced and upright in the face of gravity and ground reaction forces. As such, chronic pain and/or dysfunction that appears in one part of the body (e.g., Achilles tendonitis) usually means that other areas are dysfunctional as well. Because of the body’s interconnectedness, the entire system must be assessed to see which area or tissues are to blame for the underlying cause of someone’s aches, pains and dysfunction.
Muscles can be either too weak or too strong and tendons and/or ligaments can also be too short or over extended. Any combination of these leads to the body being pulled out of alignment resulting in pain.
Corrective exercises are exercises that a clinician prescribes to address these musculoskeletal imbalances which are causing the body to be out of alignment which causes pain.
Corrective exercise does not eliminate pain but rather eliminate the causes of pain.
