While breast health does not fall within the scope of physiotherapy, and a blocked duct would not be a physiotherapy diagnosis, this may be an activity a physiotherapist could perform under the right circumstances. The physiotherapist would need to work with a regulated health care professional who has breast health within their scope (e.g. physician, midwife, nurse practitioner) who had assessed the patient, diagnosed the blocked duct, and determined whether therapeutic ultrasound would be an appropriate treatment.
Physiotherapists should only provide the care if they have the knowledge, skills, and judgement to do so safely and competently, and have information to support it as a safe and effective treatment. The PT should work collaboratively with the referring health care provider and consider how they will monitor for efficacy of treatment and progress. The PT should also have a conversation with the patient regarding the nature of the treatment, its benefits and risks, alternatives to treatment, and provide information that the PT is working collaboratively with another health care professional. See the Collaborative Care standard for more information.
