ABSTRACT

Introduction. Certain number of patients who had suffered a cerebrovascular disease will have in the short or long term dysphagia, because the route involved in the neurological control of swallowing is injured, with the motor evoked potentials (MEPs) is possible to value the integrity of this route.
Objective. To demonstrate the sensibility of the PEMs for dysphagia detection in stroke.
Method. 15 subjects with dysphagia secondary to stroke formed the problem group; 15 healthy subjects paired for age and sex with those of the group problem, formed the control group. We realized the MEPs of muscles of the swal-lowing to both groups. The Mann-Whitney U test was used to determine significant difference between the latencies of both groups. In order to calculate the sensitivity, the endoscopic evaluation of swallowing it was realized to problem group and compared with the MEPs study. Results. The median of the latencies of MEPs for submentonianos muscles in control group was of 4.0 ms (quartil 25 = 3.8 and quartil 75 = 4.2) and for constrictor muscles was of 2.9 ms (quartil 25 = 2.6 and quartil 75 = 3.1); the values of problem group we significantly greater (p = 0.002). The sensitivity of the MEPs in both muscle groups was 100% for dysphagia detection in stroke.
Conclusions. The study of MEPs turned out to be highly sensitivy for dysphagia detection in stroke.
