OBJECTIVE: To discuss a case of coccygodynia that responded favorably to conservative chiropractic adjusting procedures with the Activator Methods Chiropractic Technique (AMCT) and the Activator II Adjusting Instrument (AAI II). CLINICAL FEATURES: A 29-year-old woman had unremitting coccygeal pain of 3 weeks' duration. The problem began after she had moved heavy boxes while at work. The pain was characterized by a continual dull ache in the coccygeal region, accompanied by intermittent sharp pain, particularly upon sitting or rising from a seated position. She had been taking self-prescribed over-the-counter analgesics (aspirin and ibuprofen) for 3 weeks without obtaining relief. INTERVENTION AND OUTCOME: Treatment consisted of mechanical force, manually assisted, short-lever (MFMA) chiropractic adjusting procedures to the coccygeal area, primarily the sacrococcygeal ligament. The AAI II was used to deliver the adjustment according to diagnostic and treatment protocol specified for AMCT. The patient experienced first treatment. CONCLUSION: Chiropractic coccygeal manipulation may be effectively delivered via instrumental adjustment in certain cases of coccygodynia. The use of an AAI II in administering the coccygeal adjustment has the benefit of being a gentle, noninvasive procedure, as well as being comfortably tolerated by the patient. This method of coccygeal adjustment may bear consideration in certain cases of coccygodynia.
