Chiropractors and return-to-work: the experiences of three Canadian focus groups.

OBJECTIVES: To explore the views of chiropractors about timely return-to-work in treating patients with musculoskeletal injuries, to identify the approaches used by chiropractors when treating injured workers with musculoskeletal disorders, and to learn about chiropractors' perspectives on the barriers and facilitators of successful return-to-work. DESIGN: Qualitative study of 3 focus groups of chiropractors. METHODS: Focus groups of 8 to 11 chiropractors were conducted in 3 large Canadian cities. The selected participants were experienced in treating patients with occupational musculoskeletal injuries. Standard questions were used to collect data. The data from each focus group were coded and analyzed separately and then considered in relation to each other. RESULTS: The participants indicated that timely return-to-work depends on patients' characteristics, severity of injury, clinical progress, the availability of work accommodation, and clinical judgment. The chiropractors commented that their treatment of injured workers rests on their strength in diagnosis and treatment and on providing patient-centered care. Positive human relations within workplaces and the ability to accommodate the work of an injured worker were described as important in return-to-work programs. The participants believed that a bias against chiropractic is present within the medical profession and workers' compensation boards. They viewed this bias as an important barrier when assisting their patients to successfully return to work. CONCLUSION: The broad approaches described by the participating chiropractors to return injured workers to work are consistent with those proposed in evidence-based practice guidelines. Better communication among chiropractors, medical doctors, and workers' compensation boards would likely decrease interprofessional tensions and improve the recovery of workers with musculoskeletal injuries.

Breathing retraining: a three-year follow-up study of treatment for hyperventilation syndrome and associated functional cardiac symptoms.

This study was designed to evaluate the long-term effects of paced diaphragmatic breathing on subjects who reported functional cardiac symptoms and who also demonstrated associated signs of hyperventilation syndrome. Subjects were a representative sample composed of 10 out of the original 41 subjects who had participated three years previously in a study designed to evaluate the short-term effects of breathing retraining on functional cardiac symptoms and respiratory parameters (respiratory rate and end-tidal carbon dioxide). The results of this follow-up study indicate that breathing retraining had lasting effects on both respiratory parameters measured. Subjects evidenced significantly higher end-tidal carbon dioxide levels and lower respiratory rates when compared to pretreatment levels measured three years earlier. Subjects also continued to report a decrease in the frequency of functional cardiac symptoms when compared to pretreatment levels. We conclude that breathing retraining has lasting effects on respiratory physiology and is highly correlated with a reduction in reported functional cardiac symptoms.

Hyperventilation syndrome and the assessment of treatment for functional cardiac symptoms.

Three methods of breathing retraining (guided breathing retraining, guided breathing retraining with physiologic monitoring of thoracic and abdominal movement plus peripheral temperature, and guided breathing retraining with physiologic monitoring of thoracic and abdominal movement, peripheral temperature and end-tidal carbon dioxide) were compared with a no-treatment control group to determine the effectiveness of breathing retraining on modifying respiratory physiology and reducing functional cardiac symptoms in subjects with signs associated with hyperventilation syndrome. Of 41 subjects studied, 16 were diagnosed with mitral valve prolapse. Results demonstrated that all 3 methods of breathing retraining were equally effective in modifying respiratory physiology and reducing the frequency of functional cardiac symptoms. Results determined that respiratory rate and subject's perception that training had generalized were the best predictors of treatment success. Furthermore, it was found that subjects with mitral valve prolapse responded as well to treatment as did those without prolapse.
