Resumo

Considering that neurogenic oropharyngeal dysphagia is a prevalent condition with or without cardiac disease we should contemplate issues surrounding cardiovascular difficulties during rehabilitation. This study aims to evaluate the effects of effortful swallowing maneuver (ESM) on heart rate variability (HRV) in subjects with neurogenic oropharyngeal dysphagia. We studied 22 individuals {[}8 Stroke and 14 Parkinson Disease (PD) subjects aged between 41 and 75 years old] with neurogenic oropharyngeal dysphagia regardless of gender. HRV was assessed under two circumstances: spontaneous swallowing versus ESM. Surface electromyography of the suprahyoid muscles was undertaken to measure the swallowing muscle excitation, which then confirmed higher muscle activity during ESM. We attained no changes in HRV between the two swallowing events {[}HR: spontaneous swallowing 78.68 +/- 13.91 bpm vs. ESM 102.57 +/- 107.81 bpm, p=0.201; RMSSD (root-mean square of differences between adjacent normal RR intervals in a time interval): spontaneous swallowing 16.99 +/- 15.65 ms vs. ESM 44.74 +/- 138.85 ms, p=0.312; HF (high frequency): spontaneous swallowing 119.35 +/- 273 ms(2) vs. ESM 99.83 +/- 194.58 ms(2), p=0.301; SD1 (standard deviation of the instantaneous variability of the beat-to-beat heart rate): spontaneous swallowing 12.02 +/- 1.07 ms vs. ESM 31.66 +/- 98.25 ms, p=0.301]. The effortful swallowing maneuver did not cause clinically significant changes in autonomic control of HR in this group of subjects with oropharyngeal dysphagia. (AU)
