The study aimed at evaluating the diadochokinetic (DDK) skills of Greek-speaking preschool children with phonological disorder (PD) by means of a structured evaluation protocol and at proposing cut-off points for children at risk of speech impairment. The participants were 36 children with PD and 60 typically developing (TD) peers. The groups were matched on age and gender. The PD group performed significantly slower than the TD group in all speech DDK tasks but not in the oral-motor tasks. The ROC analysis showed a statistically significant positive discrimination for all speech tasks. The internal consistency of the protocol was excellent (Cronbach's [alpha] = 0.844), while complex stimuli showed a better discriminatory ability. The obtained results agree with Dodd's classification for speech sound disorders (SSDs). Different types of speech stimuli must be included in the evaluation of DDK performance as a clinical predictor for preschoolers with SSDs who face difficulties in speech maturation.

Background: Diadochokinetic rates tasks are frequently used for the assessment of diadochokinesia (DKK) in young and elderly adults. However, there is scarce research on healthy elderly adults over 65 years old, and little is known about the effect of different types of stimuli (non-words/real words) in this specific population. Furthermore, the current research supports significant language variations, highlighting the need for language-specific norms. Aims: To investigate the effect of age, gender and type of stimuli (non-words versus real words) in DDK rates in healthy elderly adults of over 65 years of age, and to provide normative data for the Greek language. Methods & Procedures: The participants were 791 healthy monolingual Greek-speaking adults (531 adults, aged 20-39 years; 157 participants aged 65-74 years; and 103 participants aged over 75 years). All participants were monolingual speakers of Greek and had normal hearing acuity, which allowed them to understand and follow instructions. Participants with a medical condition, which would affect DDK rates' performance, were excluded from the study. The time-by-count method was used, and all participants had to repeat as accurately and fast as possible: (1) four disyllabic non-words (/'gaba/, /'taka/, /'kata/, /'baga/); (2) four disyllabic real words (/'kapa/, /'tapa/, /ka'la/, /'paka/); and (3) two trisyllabic non-words (/'pataka/, /'badaga/). All responses were recorded and the speech samples that did not include at least 5 s of correct repetitions were excluded from the analysis. Outcomes & Results: Age affected DDK rates significantly, with older adults achieving slower DDK rates for all speech stimuli (non-words/real words). Gender did not have an effect on the performance of DDK rates. The type of speech stimuli affected DDK rates significantly for all age groups. Analytically, trisyllabic non-word stimuli were articulated more slowly than disyllabic non-word stimuli, and real words were produced faster than non-words. A linear regression analysis revealed that only the repetition of non-words predicted 68.4% of the performance on the repetition of trisyllabic non-words. Conclusions & Implications: The above results complement prior research, which supports that real word stimuli yield faster performance than non-word stimuli. Clinicians should keep in mind that age, language and type of stimuli (non-words/real words) affect significantly the performance of DDK rates, as well as the fact that different types of stimuli tap distinct underlying levels of speech. The current research highlights the need for language-specific norms for different populations.

This study examined the performance of Greek monolingual typically developing (TD) children on diadochokinetic (DDK) rates in real words and non-words and attempted to establish normative data for Greek. The effects of age, type of stimuli and gender were investigated. A total of 380 children aged 4.0–15.0 years as well as a control group of 313 adults participated in the study. Age significantly affected DDK performance, yet normative data differ from other studies. DDK rates for bisyllabic stimuli were faster than DDK rates for trisyllabic stimuli and real words were articulated faster than non-words. Adolescents aged 13.0–15.0 years were slower than adults both in real word and in non-word /ˈpataka/ repetition. Additionally, overall boys were significantly faster than girls. These findings show the need to: (a) implement real word stimuli in DDK tasks in order to better depict an individual’s oral-motor abilities and (b) establish language-specific normative data for TD children.

Background: The Gugging Swallowing Screen (GUSS) is a bedside dysphagia screening tool that has been designed to determine the risk of aspiration in acute stroke patients. There is no evidence in the literature for the GUSS for the pediatric population. The present study aimed to determine the diagnostic accuracy of GUSS as a screening tool in the Greek language for children with dysphagia. Methods: Eighty‐Greek‐Cypriot children aged 3–12 years who had dysphagia participated in this retrospective study. The translated into Greek GUSS was administered twice (pre‐ and post‐therapy) to each patient throughout 24 sessions of dysphagia therapy. Key Results: The GUSS showed a high internal consistency (Cronbach's α = 0.826), good test–retest reliability (rs = 0.767), convergent validity compared to the Greek Pediatric Eating Assessment tool‐10 (PEDI‐EAT‐10) total score (rs = −0.365), and inter‐rater reliability (κ = 0.863). A total cutoff points equal to 13.00 was also calculated. Aspiration was identified by the GUSS with low sensitivity and high specificity (PPV 100%, NPV 57%, LR+ NA, LR− 0.79); dysphagia/penetration was identified with high sensitivity and low specificity (PPV 33%, NPV 100%, LR+ 0.102, LR− NA). Conclusions & Inferences: The pediatric version of GUSS has been found to be a valuable tool in identifying the risk of aspiration as that of adults. It proved to be used as a good screening guide for selecting and confirming the existence of dysphagia from instrumental assessments. This is the first study of the pediatric version of GUSS, and future studies on this topic are needed. [ABSTRACT FROM AUTHOR]

Background: Diadochokinetic (DDK) rate tasks are extensively used in the evaluation of speech disorders; however, it is unclear how the different types of speech stimuli affect DDK rate performance. Aims: To investigate the effect of age, gender and type of stimuli (non‐words versus real words) on the DDK rates in individuals across the lifespan and to provide normative data for Greek. Also to examine the discrimination ability of the speech DDK stimuli administered (non‐words and real words) based on a dual DDK assessment protocol using a polytomous item response theory (IRT) model. Methods & Procedure: The participants were 1747 monolingual Greek speakers (376 children, aged 4–17 years; and 1371 adults, aged 18–90+ years). All participants had normal hearing acuity which allowed them to understand and follow instructions. Participants with a medical condition or a language disorder which would affect DDK rate performance were excluded from the study. The time‐by‐count method was used, and all participants had to repeat as accurately and fast as possible: (1) four disyllabic non‐words (/'gaba/, /'taka/, /'kata/, /'baga/), (2) four disyllabic real words (/'kapa/, /'tapa/, /ka'la/, /'paka/) and (3) two trisyllabic non‐words (/'pataka/, /'badaga/). All responses were recorded and the speech samples that did not include at least 5 s of correct repetitions were excluded from the analysis. Outcomes & Results: Age affected significantly DDK rates with performance increasing gradually until approximately the age of 40 and then gradually decreasing. Gender had no effect. Overall, there was a significant advantage of disyllabic real word stimuli over disyllabic non‐word stimuli and of trisyllabic non‐word stimuli over disyllabic non‐word stimuli on DDK rates performance. IRT analysis suggested that the data fit the polytomous model reasonably well and all DDK stimuli (real words and non‐words) showed a strong relationship (loadings > 0.50) with the latent trait. Conclusions & Implications: The current study complements prior research which supports that age and type of stimuli significantly affect DDK rates performance. It is the first study, that testifies to the benefit of real‐word stimuli over non‐word stimuli on DDK rates across the lifespan in a large representative sample. The implementation of IRT analysis provides empirical evidence about the discrimination ability of the DDK stimuli administered and confirms the reliability of this dual DDK assessment protocol. These findings are valuable for clinicians who work with motor speech disorders. WHAT THIS PAPER ADDS: What is already known on this subject: Age, type of stimuli (real words versus non‐words) and language significantly affect DDK rates performance. Current research strongly suggests the administration of language‐specific norms since language‐dependent features seem to have a noteworthy effect on the DDK rates, but scarce evidence exists about the discriminatory ability of the DDK speech stimuli commonly administered. What this study adds to the existing knowledge: Conflicting findings have been reported about the effect of different types of DDK speech stimuli (real words and non‐words) but no study to date has evaluated their discriminatory abilities. The current study is the first to implement a polytomous IRT model to examine this issue. This is also the first study to attempt an investigation of the effect of types of stimuli (real words versus non‐words) on a large representative sample across the lifespan (4–90+ years) and to provide normative data for Greek. What are the practical and clinical implications of this work?: The present study offers concrete evidence about the advantage of real‐word stimuli over non‐word stimuli in Greek, as well as normative data for the Greek‐speaking populations. Moreover, the IRT analysis testifies to the discriminatory ability of real‐word and non‐word stimuli affirming the reliability of the present dual DDK assessment protocol as a psychometrically sound measure of DDK ability. The above has significant value for clinicians who work with individuals with motor speech disorders as the protocol can help them with the diagnosis and differential diagnosis of motor speech disorders.

One of the components of a dementia diagnosis is the assessment of functional abilities. These abilities are measured via screeners, such as the Instrumental Activities of Daily Living (IADL) scale. The IADL scale is a valid tool that has been adapted in many languages. This study aimed to provide a cut-off point and validate the Greek version of the IADL scale in populations with cognitive impairment. IADL data were collected from 132 individuals: 24 PD patients, 24 Parkinson's disease dementia (PDD) patients, and 24 AD patients. The remaining 60 participants were cognitive healthy adults (CHAs). The CHA group and the PD group served as the cognitively unimpaired group (CUG), while the PDD and AD groups served as the cognitively impaired group (CIG). Additionally, the MMSE, the AMTS, the Clock Drawing Test CDT, the Arizona Battery for Communication Disorders of Dementia (ABCD), the NPI, and the GDS-15 were administered to the participants. Statistically significant differences in the IADL scores were exhibited between all subgroups. The IADL scale showed high internal consistency (Cronbach's alpha = 0.890). A threshold equal to 6.00 (AUC = 0.888, p < 0.001) was estimated between the CUG and the CIG. Significant positive correlations were observed between IADL and MMSE (r = 0.764, p < 0.001), IADL and AMTS (r = 0.724, p < 0.001), IADL and ABCD (r = 0.702, p < 0.001), and IADL and CDT (r = 0.627, p < 0.001) results. Given the obtained results, the IADL scale is a valid tool for clinical use with high reliability and sensitivity. Also, the IADL scale is a valuable instrument for screening functional abilities associated with cognitive impairment. [ABSTRACT FROM AUTHOR]

Background: Screening people's cognitive skills have been proven essential for reference to full assessment. These methods include short scales, such as the Abbreviated Mental Test Score (AMTS). The AMTS is a valid 10-item questionnaire that has been translated into many languages, but not in Greek yet. The aim of this study is the validation of the Greek version of the AMTS with an additional estimation of its cutoff scores. Methods: About 132 individuals [60 controls and 72 patients (24 with Parkinson's disease (PD), 24 with Parkinson's disease dementia (PDD), and 24 with Alzheimer's disease (AD)] participated in this study. All participants besides the AMTS completed the Mini Mental State Examination (MMSE), the Tuokko's Clock Drawing Test (CDT), the Instrumental Activities of Daily Living (IADL), the Arizona Battery for Communication Disorders of Dementia (ABCD), the Hellenic versions of the Neuropsychiatric Inventory (NPI), and the Geriatric Depression Scale (GDS-15). Results: Statistically significant differences were found between all subgroups for the AMTS. The AMTS showed high internal consistency (Cronbach alpha = 0.819 and coefficient omega ω=0.814). A threshold equal to 6.50 (AUC: 0.908, p=0.000) between groups with and without cognitive impairment was calculated. The AMTS was significantly correlated with the CDT, IADL, and MMSE. Conclusion: The proposed version of the AMTS can distinguish between groups with and without cognitive impairment. Additionally, the AMTS is found to be clinically valid having high reliability and classification accuracy. Conclusively, it is a valuable instrument for screening different types of cognitively impaired patients. [ABSTRACT FROM AUTHOR]

Participants with a medical condition, which would affect DDK rates' performance, were excluded from the study. The time‐by‐count method was used, and all participants had to repeat as accurately and fast as possible: (1) four disyllabic non‐words (/′gaba/, /′taka/, /′kata/, /′baga/); (2) four disyllabic real words (/′kapa/, /′tapa/, /ka′la/, /′paka/); and (3) two trisyllabic non‐words (/′pataka/, /′badaga/).

The current research highlights the need for language‐specific norms for different populations. What this paper adds: What is already known on the subject: DDK rates are significantly affected by the types of stimuli and language used. Moreover, the normal ageing process decreases performance in terms of DDK rates, but scarce evidence exists for healthy elderly adults over 65 years old. What this paper adds to existing knowledge: Most studies have examined DDK rates in healthy elderly people with restricted samples and using non‐word stimuli. The current study administered different types of stimuli (non‐words/words) in a large sample of healthy elderly participants. This is also the first study to attempt to provide DDK normative data for this population in the Greek language. What are the potential or actual clinical implications of this work?: The results of this study strongly suggest that clinicians should bear in mind the significant impact age and language have on performance in terms of DDK rates, especially when normative data are not available for a certain language or age group. Furthermore, non‐word and real‐word stimuli cannot be used interchangeably since they tap into distinct underlying levels of speech, thus providing clinicians with useful information about the level of breakdown and the proper treatment plan.

The present study aims to be the first to validate the Tuokko version of the Clock Drawing Test (CDT) and estimate its cutoff score after its translation into the Greek language and administration in the Greek population. One hundred and thirty-two individuals participated in this study [60 with Good Cognitive Health (GCH), 24 with Parkinson's Disease (PD), 24 with Parkinson's Disease Dementia (PDD) and 24 with Alzheimer's Disease (AD)]. The CDT was administered to all participants. Additionally, the cognitive and mental status of the sample were estimated through the use of the Mini Mental State Examination (MMSE), Abbreviated Mental Test Score (AMTS), Arizona Battery for Communication Disorders of Dementia (ABCD), Instrumental Activities of Daily Living (IADL), the Neuropsychiatric Inventory (H-NPI) and the Geriatric Depression Scale −15 (GDS-15). Statistically significant differences were found between all groups on the CDT, with AD patients having lower scores than all subgroups in the study. The CDT showed a high internal consistency (Cronbach's alpha = 0.832). The ROC analysis provided a cutoff point equal to 4.00 (AUC: 0.821, p < 0.001) between the Cognitively Unimpaired Group (CUG: GCH and PD group) and the Cognitively Impaired Group (CIG: PPD and AD patients), 5.00 (AUC: 0.845, p < 0.001) between the GCH group and the PDD group, and 4.00 (AUC: 0.780, p < 0.001) between the GCH group and the AD group. Finally, the cutoff point between the PD group and the PDD group was 4.00 (AUC: 0.896, p < 0.005), and 3.00 (AUC: 0.899, p < 0.001) between the PD group and the AD group. Significant positive Pearson's correlations were observed between CDT and MMSE (r = 0.808, p < 0.001), CDT and AMTS (r = 0.688, p < 0.001), CDT and ABCD (r = 0.770, p < 0.001), CDT and the ABCD Visuospatial Construction subdomain (r = 0.880, p < 0.001); while a negative correlation was found between CDT and IADL (r = −0.627, p < 0.001) between the CUG and the CIG groups. Given the results obtained, the CDT appears to be a clinically valid screening instrument for the assessment of visuospatial abilities, with high reliability in Greek populations with cognitive impairment.

AbstractPurposeMaterials and MethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONThe Pediatric Eating Assessment Tool (PEDI-EAT-10) is a parents/caregivers screening tool that assesses pediatric patients at risk of penetration and/or aspiration symptoms. The aim of this study was the validation of PEDI-EAT-10 in the Greek language.This cross-sectional study included 222 parents/caregivers of children with (n = 122) and without (n = 100) feeding and/or swallowing disorders, with age range 3 – 12 years. The children were selected from Cypriot schools and health settings. All parents filled out the PEDI-EAΤ-10 questionnaire and after its initial completion, it was re-administered after 2 weeks.A statistically significant difference was observed in the PEDI-EAT-10 total mean scores between the study’s two groups [t (220) = 9.886, p < 0.001]. Internal consistency was high (Cronbach’s alpha= 0.801) with very good split-half reliability equal to 0.789. A significant and strong test-retest reliability was computed (r = 0.998, p < 0.001). The PEDI-EAT-10 cutoff point was 11.00 (AUC: 0.869, p < 0.001) for children with feeding and/or swallowing disorders in accordance with the PAS scale.In conclusion, the Greek version of PEDI-EAT-10 is shown to be a valid and reliable screening tool for the assessment of the pediatric population with a risk of dysphagia.The Pediatric Eating Assessment Tool (PEDI - EAT - 10) is a clinical screening tool to assess pediatric patients at risk of penetration and/or aspiration reported by parents or caregivers.This study is a cross cultural translation of PEDI - EAT - 10 in Greek language and it is proven to have excellent internal consistency, reliability, and validity.The use of PEDI – EAT – 10 will be a very useful utility for health professionals in rehabilitation settings.The Pediatric Eating Assessment Tool (PEDI - EAT - 10) is a clinical screening tool to assess pediatric patients at risk of penetration and/or aspiration reported by parents or caregivers.This study is a cross cultural translation of PEDI - EAT - 10 in Greek language and it is proven to have excellent internal consistency, reliability, and validity.The use of PEDI – EAT – 10 will be a very useful utility for health professionals in rehabilitation settings.

OBJECTIVE: Cervical spondylosis and cervical disk herniation are the most frequent forms of degenerative disease in the cervical spine. Surgical treatment mainly includes anterior cervical disk fusion. However, information concerning vestibular-evoked myogenic potential (VEMP) recording in patients undergoing cervical spine surgery is limited. The present prospective study aimed to investigate the effect of anterior disk fusion surgery on cervical VEMP (cVEMP) parameters. MATERIALS and METHODS: Twenty-five patients were enrolled in this study, and 20 patients (10 men and 10 women) completed cVEMP testing. Patient ages ranged from 29 to 76 y (mean, 52 y). Patients with conductive hearing loss or vestibular dysfunction were excluded. The cVEMP test was recorded preoperatively and 1 and 4 months postoperatively. Air-conducted tone-bursts of 500 Hz were used. RESULTS: We found no statistically significant difference between the preoperative and postoperative cVEMP values. CONCLUSION: Cervical spine surgery (anterior cervical disk fusion) for treating cervical spondylosis does not appear to affect the presence of cVEMP or the parameters of cVEMP, when using air-conducted tone-bursts of 500 Hz. Moreover, cVEMP testing can be used in the postoperative phase for evaluating vertigo in patients who have undergone anterior cervical disk fusion. [ABSTRACT FROM AUTHOR]

Introduction: In the region of Epirus (Northwestern Greece) there are characteristic climatic and geographical conditions that facilitate the growth of typical vegetation with the production of allergic pollen. Aerobiological research into airborne pollen diversity and seasonal variation in pollen counts and fungi spores has become essential due to the growing incidence of allergic rhinitis, allergic asthma, and other pollen-related and spore-related allergic conditions. Furthermore, weather conditions and other factors like air pollution may affect the intensity, the onset, and the duration of the pollen season, and the impact on the patient's symptomatology., Methods: The diversity of airborne pollen grains (grains/m 3 ) and fungal spores (spores/m 3 ) in the region of Epirus were measured volumetrically using Burgard trap for 13 months, from May 1, 2017 to May 31, 2018., Results: Totally, 10 pollen families and two fungi were recognized. The six most common taxa were Cupressaceae, Pinaceae, Urticaceae, Poaceae, Betulaceae, and Compositeae. The fungi taxa were Cladosporium and Alternaria. Peak pollen centralization was recorded from May to September. Urticaceae had the longest pollen season while Oleaceae and Pinaceae had the shorter. Fungal spores were recorded during all the months of the year. Also, there was a correlation between meteorological parameters and most pollen taxa., Conclusion: The pollen and spore calendar shows the concentration of pollen grains and fungal spores in the region of Epirus. This knowledge is important for physicians and allergic patients as it could improve the management of the allergic respiratory disease., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Komnos et al.)
