Abstract
Background: Trauma to the neck can cause acute pain. Chronic pain and dysfunction from such injury is called “whiplash-associated disorder” [WAD]. The Quebec Task Force [QTF] classified WAD severity. This case study summarizes the courses of 50 WAD patients [class 2 or 3].
Findings: Forty-three accepted intramuscular stimulation therapy. They had pain and abnormal physical signs [allodynia, trophedema, muscle knots, limited range of motion]. With treatment, twenty-nine achieved long-term improvement.
Conclusions: The symptoms were due to abnormal function of the central nervous system. Most improved subjetively and their abnormal physical signs resolved. Such direct clinical evidence of benefit is clearly meaningful.
