Sir Herbert Barker's manipulative technique Part 2
Note the tension level exhibited by the patient throughout the manipulative ordeal. This is exactly why I have never learned to appreciate ortho manual therapy.

If the patient does not have any opportunity to practice having or experiencing an internal locus of control, he or she will never learn to use it.
