The diagrams in this well-written monograph are excellent, the printing is of good size, and the bibliography is complete. The diagram on page 7 showing correct and incorrect sitting postures appears to be labeled just the opposite from what most people accept as the right and wrong positions. The outline of the physical examination is good, and the various signs and tests are clearly explained. The author is to be commended on putting into such a small book the wealth of material that is gathered here. This would be a good book for the physician to have on his desk to lend to patients who have a postural backache. The patients could thus see their own condition in the description of the fatigued back and would then more clearly understand the corrective measures being used.
