“…have been conducted to evaluate nasalization norms amount, especially in children using Nasal view software and sometimes Nasometer. These studies, albeit confirming significant differences in nasalization scores in different languages and accents, have to interpret separately [19][20][21][22]. According to the results of studies and statistical analysis, Nasometer is suitable for evaluating resonance disorders.…”

Introduction: Awareness of the nasality norm condition in normal people's speech (children and adults) is very important for assessment and treatment of nasality disorders. The main goal of this study was to determine normative nasalance scores among Persian-speaking adults. Material and Methods:In this descriptive-analytical cross-sectional study, nasalance value of 152 adults (54 males and 98 females) older than 18 years was examined by access method. Nasality test which included vowels (front/back, high/low), syllables (with oral and nasal consonants), words (with oral and nasal consonants), and sentences (with oral and nasal consonants) was done using Nasometer II model 6450. The data were then analyzed using paired t-test and Wilcoxon statistical test. Results:The results indicate that the nasalance mean score for back vowels is significantly higher than front vowels. Also, the amount of nasalance mean score for low vowels is significantly higher than that in high vowels. The results also indicate that the nasalance mean scores for syllables, words, and sentences with nasal consonants is significantly higher than those with oral consonants (P<0.001). Conclusion:The results of the present study have provided the mean scores of nasalance for vowels, syllables, words, and sentences separately with oral and nasal consonants in normal Persian-speaking adults. Also, the data obtained in this study can be used to compare the function of the resonance system in people with suspected resonant disorders.

“…Some types of objective tools include Nasometer, Nasal view, Visipich, and SNORS. Because of its gold standards, the Nasometer has many applications in clinical research [4,5]. Nasalization patterns are reported in different languages and different age groups.…”

“…When the velopharyngeal port is open during the production of nasal sounds (/m, n, and ng/ phonemes), sound energy is relatively unimpeded through the pharynx and nasal cavity. 5,10,18,22,37 Hypernasality is a resonance disorder that results from velopharyngeal inadequacy (VPI). Specifically, in patients with hypernasality, oral sounds inappropriately resonate into the nasal cavity due to inadequate closure of the velopharyngeal valve.…”

“…For example, Hutchinson et al reported nasalance scores in older healthy subjects of 23% for males and 32% for females. 10 The other studies in mixed-age groups were IrishEnglish at 26%, 46 Flemish at 33.8%, 49 Korean at 34%, 37 and Cantonese at 35.4%. 51 The reason that these different languages could be taken into account is that the efficacy of the objective (instrument-based) measurements was based on speech stimulus items.…”

“…Individuals with VPI were assumed as having hypernasality, which manifested as high nasalance scores. 5,10,18,22,37 Patients were asked to read 3 standard passages from the Thai Nasality Test. 25 The first passage is a nasal passage that is rich in nasal consonants (m, n, ng), for which the velopharyngeal valve remains open to allow sound transmission into the nasal cavity.…”

OBJECTIVE Normal pressure hydrocephalus (NPH) is clinically characterized by gait disturbance, cognitive impairment, and urinary incontinence, as well as enlargement of the ventricles. To the best of the authors' knowledge, there have been no previous publications regarding the correlation between bulbar dysfunction and NPH. The primary objective of this study was to compare preoperative and postoperative prevalence of bulbar dysfunction in patients with NPH. Secondary objectives included assessing the results of surgery for swallowing, speech, gait, cognition, and urination, and evaluating the correlation between bulbar dysfunction and triad symptoms. METHODS Fifty-three patients with NPH who underwent shunt placement surgery at Siriraj Hospital were included in the study. Patients were evaluated for gait, cognition, urination, swallowing, and speech before and 6 months after shunt placement. Triad symptoms were assessed using standard methods. Bulbar dysfunctions were assessed using the Swallowing Problem Questionnaire, Thai Articulation Test, Resonation Screening Test (RST), and Thai Nasality Test. The Thai Speech Assessment Program and nasometer were used for objective speech measurement. RESULTS Preoperatively, 86% (43/50) of patients had swallowing problems and 75% (37/49) had speech problems, as measured by the RST. Postoperatively, there was significant improvement in swallowing (p < 0.001), speech problems by RST (p = 0.008), and voice volume (p = 0.009), but no significant change in the nasometer test. All triad symptoms were improved. There were significant correlations between swallowing impairment and gait disturbance (r = 0.358, p = 0.009), and RST and cognitive impairment (r = −0.502, p < 0.001). CONCLUSIONS This is the first study of bulbar dysfunction in patients with NPH. The results showed that the prevalence of bulbar dysfunction is very high. The correlation between bulbar dysfunction and the classic NPH triad has been documented and published. These bulbar symptoms also significantly improved after surgery. As such, bulbar dysfunction should be regarded as a core symptom that should be considered along with the classic triad in the clinical diagnosis and management of NPH.
