Abstract

Objective:   To characterize muscle activity and muscle strength in patients with atypical swallowing (AS; n = 88) and competent lips (CL) or incompetent lips (IL) versus a control group (Ctrl; n = 90)

Methods and materials: an analytical case-control study was conducted using surface electromyography (sEMG) of the orbicularis oris, mentalis and masseter muscles. Compression forces of the orbicularis oris,  right  and left masseters muscle (Cfrmm, Cflmm)) , tongue tensile strength (Tts) via myoscan analysis and resistance of the orbicularis oris (Roo) via dynamometry were determined.

Comparisons were made with the Mann-Whitney U test   under a 95% confidence interval.

Results: The amplitude of the sEMG record of the orbicularis oris muscle, in maximal contraction, was lower (p<0.01) in the atypical swallowing group (596.40 ± 175.83) compared to controls (659.83 ± 203.79). The muscle strength studied in the experimental group was lower (p<0.01) than in controls (CFo: AS: 0.31 ± 0.13; Ctrl: 0.38 ± 0, 11; Cfrmm: AS: 0.40 ± 0.08; Ctrl: 0.50 ± 0.11; Cflmm: AS: 0.41 ± 0.08; Ctrl: 0.58 ± 0.59; Tts, AS: 0.52 ± 0.14, Ctrl: 0.65 ± 0.14, and Roo: AS: 2.47 ± 0.61; Ctrl: 2.73 ± 0.60). Patients with incompetent lips had a greater muscle activity of the orbicularis oris in swallowing (AS of IL: 197.01 ± 85.84; AS of CL: 160.54 ± 97.03; Ctrl: 147.18 ± 80.10).

Conclusion: Patients with atypical swallowing showed differences in the strength of studied muscles and the muscle activity of the orbicular oris muscle compared to controls.
