Olfaction Modulates Inter-Subject Correlation Of Neural Responses, Paul Deguzman, Anshul Jain, Matthias H. Tabert, Lucas C. Parra

Publications and Research

Odors can be powerful stimulants. It is well-established that odors provide strong cues for recall of locations, people and events. The effects of specific scents on other cognitive functions are less well-established. We hypothesized that scents with different odor qualities will have a different effect on attention. To assess attention, we used Inter-Subject Correlation of the EEG because this metric is strongly modulated by attentional engagement with natural audiovisual stimuli.We predicted that scents known to be “energizing” would increase Inter-Subject Correlation during watching of videos as compared to “calming” scents. In a first experiment, we confirmed this for eucalyptol and …

Assessment Of Intrinsic Hand Neuromuscular Physiology, Philemon Tsang

Electronic Thesis and Dissertation Repository

Alterations to the peripheral nervous system and neuromuscular physiology may impact hand function in a typical or clinical population, such as individuals with ulnar neuropathy. The mechanisms that influence these positive and negative changes are still not well understood. The three studies within my thesis aim to validate the reliability of decomposition-based quantitative electromyography (DQEMG) measurements and explore the changes in intrinsic hand neuromuscular physiology in a typical aging population and individuals recovering from a surgical intervention for severe ulnar neuropathy.

The purpose of the first study was to determine the test-retest reliability of near-fibre (NF) jiggle, a measure of …

Reliability And Validity Of The Turkish Version Of The Vocal Fatigue Index, Seher Şi̇ri̇n, Mehmet Fati̇h Öğüt, Cem Bi̇lgen

Turkish Journal of Medical Sciences

Background/aim: The aim of this study is to evaluate the reliability and validity of the Turkish version of the Vocal Fatigue Index (VFI). Materials and methods: The study was conducted with 535 participants including 285 patients with voice disorders and 250 healthy controls. Internal consistency and test-retest reliability were calculated for the reliability analysis. The mean VFI factor scores of both groups were compared. The strength and direction of the relation between VFI and Voice-Related Quality of Life (V-RQOL) measure was evaluated for the validity analysis. Results: The Cronbach's alpha coefficient of VFI factor scores was found to be 0.920 …

Cross-Cultural Adaptation, Reliability And Validity Of The Turkish Version Of Patient-Specific Functional Scale In Patients With Chronic Neck Pain, Gamze Yalçinkaya, Bi̇lge Kara, Mehmet Nuri̇ Arda

Turkish Journal of Medical Sciences

Background/aim: Current clinical guidelines recommend to use both clinical and self-reported measurements for evaluation of chronic neck pain. Among the self-reported outcomes, Neck disability index and patient-specific functional scale are the most widely used and recommended instruments. The purpose of our study was to determine the test-retest reliability and validity of patient-specific functional scale which was not validated in Turkish language previously. Materials and methods: Translation and adaptation process had conducted according to the Beaton et al. Sociodemographic data, Turkish version of patient-specific functional scale and neck disability index were recorded at the initial assessment. Retest assessment was produced for …

Validity And Reliability Study Of The Turkish Version Of The Self-Efficacy For Managing Chronic Disease 6-Item Scale, Kübra İnci̇rkuş, Nursen Nahci̇van

Turkish Journal of Medical Sciences

Background/aim: The measurement of self-efficacy is an important step toward improving chronic disease management, enhancing adherence to treatment, and assessing patients with chronic diseases. The purpose of this study was to assess the validity and reliability of the Turkish version of theSelf-Efficacy for Managing Chronic Disease 6-Item Scale. Materials and methods: In this methodological study, the sample consisted of 211 patients receiving chronic disease care in 2 family health centers in İstanbul, Turkey. Data were analyzed with descriptive statistics, exploratory and confirmatory factor analyses, concurrent validity, Cronbach's alpha, item-total correlation, and test-retest reliability.Results: Most of the sample were women (72%), …

Validity And Reliability Of The Turkish Version Of The Multidimensional Dyspnea Profile Inoutpatients With Respiratory Disease, Buse Özcan Kahraman, Turhan Kahraman, İsmai̇l Özsoy, Ayli̇n Tanriverdi̇, Asli Papurcu, Nazeni̇n Hande Sezgi̇n, Karya Polat, Serap Acar, Ayli̇n Özgen Alpaydin, Can Sevi̇nç, Sema Savci

Turkish Journal of Medical Sciences

Background/aim: Dyspnea is the subjective feeling of breathing discomfort, which is a significant problem for patients with heart and respiratory disease and also an important determinant of exercise tolerance, quality of life, and mortality in various diseases. Most of the scales are not enough to investigate the multidimensional effects of dyspnea; therefore, the Multidimensional Dyspnea Profile (MDP) was developed and validated in many languages. This study aimed to translate and culturally adapt the MDP into Turkish and investigate the psychometric properties of this adapted version in outpatients with respiratory disease. Materials and methods: The MDP was translated and culturally adapted …
