In the United States, adults experiencing lower back pain (LBP) have reported using alternative health care to manage symptoms. Chiropractic techniques, relaxation, and massage have been cited as the most commonly used alternative therapies. Electro-acupuncture (EA), along with conventional health care, has been found to be a useful complementary and alternative medicine (CAM) modality in alleviating the disability associated with LBP. The purpose of this single-subject case study was to evaluate the daily activity pattern effects of EA and CAM modality usage on pain intensity levels and functional status of an adult experiencing LBP. Activity patterns and pain intensity ratings were recorded for two consecutive weeks through the use of a daily pain diary in natural environments. Results from the data analyses revealed daily LBP intensity ratings ranging from slight to moderate pain. On average, the participant reported using approximately ten CAM modalities per day. The participant reported decreases in pain intensity levels, increases in energy levels, and feeling better after EA and acupuncture treatments, maintaining an exercise and weight loss regimen, taking megavitamins, drinking teas, praying, singing, and using humor, distraction, and relaxation techniques. Use of herbs and too much exercise were the least effective. Findings suggest that for this patient, EA and certain CAM modalities were effective interventions that promoted well-being and self-healing. In addition, the daily pain diary was found to provide rich research and assessment data.
