The aims of this study were: (i) to investigate the effect of
functional magnetic stimulation on total colonic transit time in patients with
Parkinson's disease; (ii) to compare the changes in dynamic recto-anal behaviour
during filling and defaecation in response to this regimen; and (iii) to study
the carry-over effects with a 3-month follow-up. DESIGN: A longitudinal,
prospective before-after trial. SUBJECTS: Sixteen patients with Parkinson's
disease enrolled in this study. No subject withdrew from the study as a result of
serious adverse events. METHODS: A 3-week magnetic conditioning protocol,
consisting of a 20-min stimulation session twice daily. Colonic transit time,
Knowles-Eccersley-Scott Symptom Questionnaire and the dynamics of defecography
were carried out before the intervention and on the final day of the protocol.
Results and conclusion: There was a statistically significant reduction in
colonic transit time and in the questionnaire score following the intervention.
The difference in the anorectal angles between resting and evacuating process and
the changes in pelvic floor descent all reached significance after the
intervention. The therapeutic effects that achieved significance remained
constant in the 3-month follow-up result. Functional magnetic stimulation may
facilitate colonic motility in Parkinson's disease and straighten the anorectal
angle, allowing smooth access of rectal contents to the anal canal.
