People and SLTs may often believe that someone who has a swallowing or communication problem got better because of a specific therapy they were given. People may also believe that someone got worse because of a therapy or intervention.
Although a person got better after therapy, it may not have been the cause. It’s possible they would have got better without intervention. Also, we all respond in different ways, so even if an intervention did help one person, it may not have the same effect for everyone.
BEWARE when a therapist or service user says: “It worked for me.”
