"It is critically important for the chiropractic profession to document the full gamut of conditions it both diagnoses and treats; this allows for better standards of care to be set and it provides a rationale for developing clinical trials. But this also requires a greater level of precision in the reporting of these cases."

-Dana J. Lawrence, Editor, Journal of Manipulative & Physiological Therapeutics, 1993; 16(3):123.

The reporting a case provides a detailed description of interesting and useful clinical information to other practitioners and the general public. Case reports are educational, discussing unusual cases or novel clinical approaches to advance the current knowledge base. Case reports assist in documenting the standard and range of chiropractic care, and in doing so they disseminate both the benefits and limitations of chiropractic care in the literature.

Together with Dr. Brad Polkinghorn (Santa Monica, CA) I have co-authored several case reports on important cases responding to chiropractic care. In 1998, we published on chiropractic treatment of a patient with lumbar disc herniation (Polkinghorn and Colloca, 1998). This patient was diagnosed with a 6 mm central disc protrusion and presented with accompanying leg pain and neurological deficit in combination with discogenic pseudoradicular pain to the anterior thigh. Chiropractic adjustments utilizing Activator Methods Chiropractic Technique (AMCT) were associated with complete resolution of the patients condition which was maintained at a 1 year follow-up.

In 1999, we wrote about a patient presenting with coccygodynia who also responded favorably to chiropractic care utilizing AMCT procedures (Polkinghorn and Colloca, 1999). In, 2000, Dr. Polkinghorn and I submitted another case report describing chiropractic management of a patient with post-surgical cervical spine pain that also resolved through chiropractic management. (Polkinghorn and Colloca, 2001). These interesting cases, and others published by Dr. Polkinghorn (Polkinghorn, 1998;Polkinghorn, 1995;Polkinghorn, 1994) have described unique cases responding to chiropractic care incorporating AMCT.

If you have an interest in publishing a case report, see below for information on how to get started.

Structured Abstracts for Case Reports Submitted to the Journal of Manipulative & Physiological Therapeutics

(From: Lawrence DJ. Structured abstracts for case reports published in JMPT. 1993; 16(3):123-4.)


The objective describes what the case report attempts to accomplish. Is it presenting a rare case? Or, perhaps, is it describing an unusual response to treatment. Here, in a short few sentences, you describe the intent and importance of the report.

Clinical Features

This section lists the important clinical features of the condition discussed, including important physical findings, neurological and orthopaedic findings, radiographic or other imaging results and any other special studies performed.

Intervention and Outcome

Describe the type of care rendered to the patient and the ultimate response to therapy.


What was learned from this case? What did the author conclude, and what recommendations might be made.
Above, this represents the structured abstract of a case report submitted to the JMPT.
