Spreken met ondersteuning van gebaren (SMOG) is een Vlaamse vorm van key word signing(KWS), waarbij men kernwoorden in een zin ondersteunt met gebaren. Deze masterproefonderzoekt de invloed van de trainingsmethode, gebarenkenmerken en attitude op hetonthouden van SMOG-gebaren en eventuele attitudeverandering na het volgen van een KWS-training bij volwassenen. Uit de resultaten blijkt dat gebaren beter onthouden worden, indienze aangeleerd werden via videofeedback in combinatie met een fotobundel. Daarnaasthebben zowel fonologische, iconische als referentiële gebarenkenmerken een effect op deleerbaarheid van gebaren. De attitude tegenover SMOG blijkt weinig invloed te hebben op degebarenkennis, en niet significant te veranderen door het volgen van een KWS-training.

Background. Globus is the uncomfortable feeling of a lump in the throat. Although a lot of research has been done on the subject, the etiology remains unclear. Chen et al. (2009) suggested visceral hypersensitivity and aberrant symptom referral as a possible cause. Aim. To assess differences in perception thresholds and symptom location during repeated esophageal and UES balloon distension in subjects with and without globus.Methods. 44 globus patients and 25 healthy controls participated. Perception and discomfort thresholds were assessed using stepwise isobaric esophageal balloon distensions (2mmHg/30sec). The barostat balloon was located in the UES and in the esophageal body 10 cm below the UES. Both tests were repeated, with the second measurement immediately following the first. Location of perception was indicated on a body map. A mixed procedure, two-way ANOVA, was used to analyze the data. Results. Patients showed more proximal discomfort during the second esophageal distension in comparison the first distension (1.62 cm vs. 2.39 cm above the xyphoid, p=0.0030), whereas controls showed no significant changes. Patients showed lower discomfort thresholds at second distension (sensitization, from 21.41 mmHg vs. 17.19 mmHg, p<.0001) whereas controls did not show any significant changes. Combined, this indicates that the lower the discomfort thresholds, the higher patients perceive the sensation of discomfort, as confirmed by mixed regression analysis. Conclusion. Globus patients perceive the sensation evoked by repeated esophageal balloon distension significantly higher than healthy control. In addition, patients show lowered discomfort thresholds during the second compared to the first distension sequence, whereas controls show no significant changes. We can conclude that the globus patients are characterized by sensitization upon repeated esophageal distension, corresponding with increased height of symptom perception.
