In Proceedings of the 1991 International Conference on Spinal Manipulation, FCER; 227-229. In this paper, it is suggested that chiropractic adjustments, at least in patients with acute musculoskeletal problems, may enhance brain function. The research modality used was brain stem evoked response or BSER - a measure of how well brain waves travel (in this case following a sound through a headphone). Four patients with acute musculoskeletal complaints and seven patients with no acute problems were adjusted with diversified technique and cranial adjusting. The four acute patients showed a shorter BSER latency period, indicating that the neural messages were going through their brain stems and auditory nerves more quickly or with less delay. This study supports the hypothesis that brain stem function can be improved by chiropractic adjustments in patients with acute musculoskeletal complaints.
