Final answer:
The study by Galek et al. (2020) supports that sEMG visual and clinician verbal feedback increases swallow effort ratio (SER), although the provided reference is unrelated.
Step-by-step explanation:
According to the study by Galek et al. (2020), it was found that surface electromyography (sEMG) visual and clinician verbal feedback does increase swallow effort ratio (SER). This suggests that when patients can see their muscle activity on a screen (sEMG visualization) and receive encouragement or instructions from a clinician, their effort in performing a swallow may be enhanced. While the question refers to Galek et al., 2020, it should be noted that the reference provided is Soussignan, R. (2002), which deals with the facial feedback hypothesis. However, this hypothesis may parallel the concept studied by Galek et al., implying that feedback mechanisms are significant in modifying physiological efforts.
