Fähigkeit von Patienten mit einer peripheren Fazialisparese zur Erkennung von Emotionen – Eine Pilotstudie

Abstract

The present pilot study does not prove any impact on this specific patient group's ability to recognize emotions and facial laterality. For future studies the research question should be verified in a larger sample size.

Is There a Difference in Facial Emotion Recognition after Stroke with vs. without Central Facial Paresis?

“…Our results reveal significant deficits in terms of accuracy of facial emotion recognition, in contrast with other studies that did not report any differences, e.g., [ 27 , 28 , 34 ]. This fact may be due to the large sample size (participants with facial paresis: n = 34; participants without facial paresis: n = 29) and the inclusion of different phases post-onset, with a wide range since the time of stroke (day 5 up to day 6361 post-onset).…”

However, previous studies reported significant limitations in terms of average time taken for facial emotion recognition, e.g., [27,28], while the participants in the present study showed faster reaction times. This, in turn, could indicate that the participants after stroke replied quick and dirty [63], while they suffered from other impairments, such as deficits in attention, concentration and memory [64], in addition to the facial paresis after stroke.…”

“…Significant deficits in facial emotion recognition were reported by Konnerth et al [ 27 ] and Storbeck et al [ 28 ] in patients with peripheral facial paresis/paralysis. Konnerth et al [ 27 ] reported that patients achieved lower accuracy values than healthy controls, although the difference was not significant.…”

“…Storbeck et al [ 28 ] also detected that accuracy in facial emotion recognition did not differ significantly between patients with facial paresis and healthy controls. However, visual emotion recognition was significantly slower compared to the control subjects in both studies [ 27 , 28 ]. More specifically, Korb et al [ 29 ] reported differences depending on the paralysed side of the face, with facial emotion recognition being more affected in patients with left-sided rather than right-sided facial palsy.…”
