A study published this month in the Journal of Pain by researchers at the Rutgers School of Dental Medicine finds a relationship between the level of postexercise pain sensitivity and the likelihood of developing chronic pain. The results suggest that exercise could be a valuable component in helping doctors predict susceptibility to pain, particularly following injury or surgery.
The phenomenon of pain reduction after exercise is known as "exercise-induced hypoanalgesia" or (EIH). The authors believe that an individual's EIH profile can indicate how efficiently their body modulates pain. Chronic pain conditions such as fibromyalgia, migraine, chronic low back pain, and temporomandibular disorder have been shown to be associated with faulty pain modulation.
