The study is the first study to investigate the treatment of chronic refractory constipation using low-level laser therapy (LLLT), to essentially enhance the defecation reflex. The patients are monitored in Dr. Jihong Chen’s colon motility clinic at McMaster University Medical Center.
What is low-level laser therapy?
Low-level laser therapy, also called photobiomodulation or neuromodulation, provides red and infrared light energy non-invasively to the sacral nerves and sacral neuronal center of the defecation reflex, to restore motility homeostasis. Low-level laser therapy has already been proven to be effective in treating back pain with a variety of neurological conditions. The same Health Canada-approved protocol for lower back pain is used in this study.
- Adults aged 18 - 95
- Diagnosis of chronic refractory constipation
- Without contraindications for low-level laser therapy
- 8 one-hour visits over 3 weeks
What the study involves?
The LLLT therapy consists of 8 treatment sessions. Treatment effects will be assessed using symptoms and quality of life questionnaires, as well as physiological anorectal motility tests and autonomic assessments before, during and after the LLLT treatment.
Parking reimbursement will be provided.
