Transcutaneous neuromuscular electrical stimulation (VitalStim) curative therapy for severe dysphagia: myth or reality?
VitalStim therapy was approved by the US Food and Drug Administration in 2001 for the treatment of dysphagia through the application of neuromuscular electrical stimulation to cervical swallowing muscles. This approval was based upon submission of data on more than 800 patients who received this therapy collected by the principal developer and patent-holder of the device. The therapy is marketed as successful in restoring long-term swallowing function in 97.5% of dysphagic patients past the point of requiring a feeding tube and as significantly better than existing therapies. More than 2,500 speech-language pathologists have taken the certification course, and thousands of devices have been sold. To date, however, aside from the developer's own studies, there are no peer-reviewed publications supporting these claims. We sought to evaluate the effectiveness of VitalStim therapy in a heterogeneous group of dysphagic patients. ⋯ VitalStim therapy seems to help those with mild to moderate dysphagia. However, the patients with the most severe dysphagia in our study did not gain independence from their feeding tubes. The authors conclude that VitalStim therapy clearly has a place in the management of dysphagia, but that the most severely afflicted are unlikely to gain dramatic improvement.
