There's been a big misunderstanding in the medical SLP space...
You've probably heard someone say:
"NMES doesn't work."
Or...
"Research shows it isn't any better than traditional dysphagia therapy."
It's true that there are published studies reporting findings like these.
Two of the most frequently cited are the studies by Langmore et al. and Humbert et al.
However, it's important to ask...
Which NMES protocol did they actually study? Because it wasn't Ampcare's Effective Swallowing Protocol (ESP).
Before we take the results of any NMES study and apply them to every form of NMES, we should ask:
➡️ Which NMES device was used?
➡️ Where were the electrodes placed?
➡️ What stimulation parameters were used?
➡️ Was the stimulation sensory-level or motor-level?
➡️ What swallowing exercises were performed during stimulation?
➡️ What patient population was studied?
"NMES" isn't one standardized treatment. Different devices, electrode placements, stimulation parameters, exercise protocols, and patient populations can all influence outcomes.
That's why evidence-based practice means looking beyond a study's conclusion and asking what intervention was actually tested before assuming the findings apply to every NMES protocol.
The takeaway: research findings should be interpreted in the context of the specific NMES protocols they evaluated, not automatically generalized to all forms of NMES!
Share this with SLP colleagues who have been contemplating adding NMES to their practice.
