Reddit mentions of Gonstead Chiropractic Science and Art - Roger W. Herbst DC - B&W

Well, you were mistaken. Motion palpation is key, and the Gonstead method of MP works better for me than the MPI stuff did.

Yes, the Gonstead model of subluxation is questionable, but the "why" to adjust is one thing, while the "how and where" is another. I'm no "Gondroid", I mix it up quite a bit, but his methods are good.

You should read up on it. It's fascinating. Check out the book.

Good for you for wanting to understand the 300+ named techniques in chiropractic!
Technique Systems in Chiropractic is a great overview of a handful of the techniques - CBP, BEST, Activator, Cranial, Cox, Diversified, DNFT, AK, Gonstead, etc., etc. I haven't read it, but a professor provided me with her summary notes, and it's been great to understand the premise and any supporting evidence.

Gonstead has its own book covering the philosophy and the basic adjustments.

A few others to consider:

• The Chiropractic Theories: A Textbook of Scientific Research
  
  
• Technique Skills in Chiropractic
  
  
• Principles and Practices of Chiropractic
  
  I think it's a great idea to read the books and get an idea of the main premise or philosophy of the technique before shelling out the hundreds to thousands of dollars to take the seminars.
  
  Good luck to you!
