Efficacy of functional magnetic stimulation in neurogenic bowel dysfunction after spinal cord injury.

OBJECTIVE The aims of this study were to assess the usefulness of functional magnetic stimulation in controlling neurogenic bowel dysfunction in spinal cord injured patients with supraconal and conal/caudal lesions, and to investigate the efficacy of this regimen with a 3-month follow-up. DESIGN A longitudinal, prospective before-after trial. SUBJECTS A total of 22 patients with chronic spinal cord injured and intractable neurogenic bowel dysfunction. They were divided into group 1 (supraconal lesion) and group 2 (conal/caudal lesion). METHODS The colonic transit time assessment and Knowles-Eccersley-Scott Symptom Questionnaire were carried out for each patient before they received a 3-week functional magnetic stimulation protocol and on the day following the treatment. RESULTS AND CONCLUSION Following functional magnetic stimulation, the mean colonic transit time for all patients decreased from 62.6 to 50.4 h (p<0.001). The patients' Knowles-Eccersley-Scott Symptom scores decreased from 24.5 to 19.2 points (p<0.001). The colonic transit time decrement in both group 1 (p=0.003) and group 2 (p=0.043) showed significant differences, as did the Knowles-Eccersley-Scott Symptom score in both groups following stimulation and in the 3-month follow-up results (p<0.01). The improvements in bowel function indicate that functional magnetic stimulation,featuring broad-spectrum application, can be incorporated successfully into other therapies as an optimal adjuvant treatment for neurogenic bowel dysfunction resulting from spinal cord injury.
