Yet, available tools to monitor the recovery of tactile sense have been criticized for their lack of validity. However, the precise quantification of AA dynamics by three-dimensional (3-D) imaging could serve as an accurate surrogate to monitor recovery following digital nerve repair. For validation, AAs were marked on digits of healthy volunteers to simulate the AA of an impaired cutaneous innervation. Three dimensional models were composed from raw images that had been acquired with a 3-D camera (Vectra H2) to precisely quantify relative AA for each digit (3-D models, n= 80). Operator properties varied regarding individual experience in 3-D imaging and image processing. Additionally, the concept was applied in a clinical case study. Images taken by experienced photographers were rated better quality (p< 0.001) and needed less processing time (p= 0.020). Quantification of the relative AA was neither altered significantly by experience levels of the photographer (p= 0.425) nor the image assembler (p= 0.749). The proposed concept allows precise and reliable surface quantification of digits and can be performed consistently without relevant distortion by lack of examiner experience. Routine 3-D imaging of the AA has the great potential to provide visual evidence of various returning states of sensation and to convert sensory nerve recovery into a metric variable with high responsiveness to temporal progress.

T1 - Preconceptions and Consultant Experience of Sport Psychologists in Deaf Sport T2 - Talententwicklung und Coaching im Sport N2 - Introduction: Consultant Effectiveness is one of the main pillars of successfully implementing Psychological Skills Training (PST) in both elite mainstream and disability sports (Martin, 2015; Vealey, 2007). Yet, there is a dearth of research on the articularities of PST consultation in elite Deaf Sport (Schliermann, 2015). Since hearing impairments have multiple intrapsychic as well as interpsychic implications (Leigh & Andrews, 2016), it might influence Consultant Effectiveness in Deaf Sport. Therefore, the main purpose of this exploratory study was to investigate preconceptions and actual experience of sport psychologists in regard to the consultation of elite deaf and hard-of-hearing (HOH) athletes. Method: A self-constructed questionnaire was administrated to 93 accredited sport psychology consultants (Mconsultant-years = 10.78) in German-speaking countries. They were asked about their awareness, opinions and experience with deaf and HOH athletes. Results: Seven consultants (8%) reported ever to have worked with a deaf or HOH athlete. Four had ever watched a competition of the Deaflympics in comparison to 77 who had watched one of the Paralympic games. Yet most subjects (71%) declared their willingness to work with deaf or HOH athletes regardless of their years of experience as consultants or prior contact with deaf or HOH individuals. In addition, the vast majority of the sample evaluated the implementation of common PST techniques in Deaf Sport as potentially “very effective” or “extremely effective”. When asked about potential particularities in the work with this group of athletes, most consultants focused mainly on communication issues. Conclusion: The analyses revealed a lack of awareness of elite Deaf Sport within the professional sport psychology communities in Germany, Austria and Switzerland. Furthermore, a low rate of professional PST implementation in elite Deaf Sport was found in these countries. Considering the lack of experience and knowledge about the particularities in Deaf Sport, further research is needed to provide hearing consultants with tools to understand the world of elite deaf and HOH athletes beyond the means of communication with them.

Die vorliegende empirische Studie analysiert die Anwendbarkeit des TOPS-D1-Fragebogens als geeignetes Diagnostikverfahren für hörbeeinträchtigte Spitzenathlet_innen.

Im Hauptergebnis ist festzuhalten, dass psychometrisch geprüfte standardisierte Fragebögen bei hörbeeinträchtigten Athlet_innen nur eingeschränkt eingesetzt werden können. Darüber hinaus sind auch beim Trainingsprozess besondere Rahmenbedingungen zu beachten.

Nasal breathing difficulties are a significant health concern, leading to substantial healthcare costs for patients. Understanding nasal airflow dynamics is crucial for comprehending respiratory mechanisms. This article presents a detailed study using tomo-Particle Image Velocimetry (PIV) to investigate nasal airflow dynamics while addressing its accuracy. Embedded in the OpenNose project, the work described aims to provide a validation basis for different numerical approaches to upper airway flow. The study includes the manufacturing of a transparent silicone model based on a clinical CT scan, refractive index matching to minimize optical distortions, and precise flow rate adjustments based on physiological breathing cycles. This method allows for spatial high-resolution investigations in different regions of interest within the nasopharynx during various phases of the breathing cycle. The results demonstrate the accuracy of the investigations, enabling detailed analysis of flow structures and gradients. This spatial high-resolution tomo-PIV approach provides valuable insights into the complex flow phenomena occurring during the physiological breathing cycle in the nasopharynx. The study's findings contribute to advancements in non-free-of-sight experimental flow investigation of complex cavities under nearly realistic conditions. Furthermore, reliable and accurate experimental data is crucial for properly validating numerical approaches that compute this patient-specific flow for clinical purposes.

Due to its composition of water, mucins, and other biomolecules, it has a complex viscoelastic rheological behavior. This interplay of both viscous and elastic properties has not been fully described yet. In this study, we characterize the rheology of human mucus using oscillatory and transient tests. Based on the transient tests, we describe the material behavior of mucus under stress and strain loading by mathematical models. METHODS: Mucus samples were collected from clinically used endotracheal tubes. For rheological characterization, oscillatory amplitude-sweep and frequency-sweep tests, and transient creep-recovery and stress-relaxation tests were performed. The results of the transient test were approximated using the Burgers model, the Weibull distribution, and the six-element Maxwell model. The three-dimensional microstructure of the tracheobronchial mucus was visualized using scanning electron microscope imaging. RESULTS: Amplitude-sweep tests showed storage moduli ranging from 0.1 Pa to 10000 Pa and a median critical strain of 4 %. In frequency-sweep tests, storage and loss moduli increased with frequency, with the median of the storage modulus ranging from 10 Pa to 30 Pa, and the median of the loss modulus from 5 Pa to 14 Pa. The Burgers model approximates the viscoelastic behavior of tracheobronchial mucus during a constant load of stress appropriately (R2 of 0.99), and the Weibull distribution is suitable to predict the recovery of the sample after the removal of this stress (R2 of 0.99). The approximation of the stress-relaxation test data by a six-element Maxwell model shows a larger fit error (R2 of 0.91). CONCLUSIONS: This study provides a detailed description of all process steps of characterizing the rheology of tracheobronchial mucus, including sample collection, microstructure visualization, and rheological investigation. Based on this characterization, we provide mathematical models of the rheological behavior of tracheobronchial mucus. These can now be used to simulate mucus flow in the respiratory system through numerical approaches.
