In one of last year's columns, I dealt with the problems surrounding the use of progress notes in a busy chiropractic practice and discussed the concept of the daily patient record. The daily patient record provided the patient several methods for documenting the level of pain currently being experienced through the use of the visual analog scale and the "dollar's worth of pain" analogy. Furthermore, through the use of the pain drawing, the daily patient record provided a means of obtaining a visual record for the patient's current pain.
The current discussion will center around a more detailed examination of the use of the pain drawing. Pain drawings provide the physician with a means of quickly assessing the patient's levels of pain. The pain drawing can demonstrate whether the patient is demonstrating symptoms consistent with an organic lesion, whether the patient is amplifying pain levels, or if there are non-organic factors involved in the patient's case. Several pain drawings rating systems have been proposed for the analysis of pain drawings.
The following rating system was proposed by Hildebrandt1 and provides the physician with a means of numerically rating the pain drawing. This system was a modified version of the system originally proposed by Ransford.2
Scoring System for Pain Drawings
I. Unreal drawings. If one or more of the following pain localizations are drawn in, two points are assigned.
A. Total leg pain
B. Frontal aspect of one or both legs
C. Unilateral or bilateral anterior tibial pain
D. Back of leg (isolated, knee included)
E. Circumferential thigh pain
F. Lateral whole leg pain (trochanteric area and lateral thigh allowed) G. Bilateral foot pain H. Circumferential foot pain I. Anterior knee pain, ankle pain J. Spotted bounds of pain scattered about the whole leg K. Whole abdomen pain
II. Drawings showing "expansion" or "magnification" of pain (one or two points per area, depending upon extent)
A. Back pain radiating to the iliac crest, groin, or anterior perineum (coccygeal pain allowed). Note: Rule out sacroiliac joint dysfunction.
B. Pain drawn outside the outline as an indication of magnification.
III. "I particularly hurt here" indicators (each category scores one point.
A. Additional explanatory notes
B. Circle painful areas
C. Draw lines to demarcate painful areas
D. Use arrows to describe anatomically not explainable pain E. Use of additional symbols
IV. "Look how bad I am" indicators. (Score one with small areas and score two with larger areas.)
A. Additional painful areas in the trunk, head, neck, or upper extremity dawn in.
With this rating system, a score of three or more is generally thought to represent a pain perception that may be influenced by psychological factors. Some of the readily apparent expressions of psychological distress include pain distributions that are non-anatomic or bizarre, drawings showing "magnification" or "expansion" of symptoms, and drawings that demonstrate "look how bad I am indicators."
Uden3 proposed an observational system for assessment of pain drawings. Uden's system relies on the impression formed by physicians familiar with low back disorders, who categorize the drawings into one of four categories: organic, possibly organic, possibly non-organic, or non-organic. This rating system demonstrated that even when one is inexperienced with the use of pain drawings, the intraexaminer reliability was 80 percent and the interexaminer reliability was 70 percent. By using one of these two systems for rating the pain drawing, the clinician can gain insight into the possibility of the presence of psychological distress which may complicate the patient's case. The following cases are provided as examples of pain drawings for various cases:
34-year-old female who was injured in a grocery store parking lot. Through cursory observation, this pain drawing has a "non-organic" appearance. Through the pain drawing scoring system, this drawing received a score of 8.

When I graduated from chiropractic college in 1981 and started practice, I heard it all, and very little was positive. “You are a quack; you do not know what a subluxation is; you couldn’t get into a real health care program, so you chose the one that is slightly above a mail-order degree; you have no proof that chiropractic works; Are you really licensed?”, and so much more.

A central challenge in creating our identity is that chiropractic is a method of care, not a technique or procedure. This is an important concept for us to promote. Our patients are treated with lifestyle modification, exercise, nutritional supplements, diet and a whole-body approach to accelerate the natural healing process. We are not simply CMT providers.
The results of a global survey released late last year (2023) unveiled some startling findings among medical and nursing students. The “Clinician of the Future: 2023 Education Edition” surveyed 2,212 students, of which 446 were in the United States, from 91 countries.
