RESUMEN
Background: The survival rate in premature infants (PIs) has increased, but many have medical and developmental complications. Difficulty with sucking, swallowing, and poor nourishment are common complications. This study aimed to investigate the effects of Kinesio-tape (KT) combined with premature infant oromotor intervention (PIOMI) on feeding efficiency (mean volume intake [%MV]), oromotor skills (Preterm Oral Feeding Readiness Assessment Scale [POFRAS]), and weight gain in PIs. Methods: In this single-subject study, 5 PIs with feeding problems were received the PIOMI-KT for 7 consecutive days. The main outcome measure was the POFRAS scale. The %MV and weight gain were the secondary outcome measures. Measurements were taken before treatment (T0), after the 4th session (T1), and after the 7th session (T3). Results: The POFRAS scores, %MV, and weight gain improved in all infants after treatment. The maximum and minimum change in level between the baseline and treatment phase was +26 and+16 for POFRAS, +54 and, +34 for %MV, +180, and +100 for weight gain. The treatment trend was upward for all infants and shown by the directions of the slopes indicated by positive values. The feeding problems were resolved in all infants after the 7th treatment session. Conclusion: The combination therapy of PIOMI-KT improved feeding function in PIs.
RESUMEN
Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by severe communication deficits and limited and repetitive behavioral tendencies. There are several treatment approaches and methods for minimally verbal children with ASD; nonetheless, there is inconclusive evidence about how early lexical development could be improved. The present study aimed to investigate the effect of combined intervention derived from the principles of different theories-including contemporary behaviorism, schemas, sociocultural, and event representation theories-to improve early lexical development in minimally verbal children with ASD. Methods: In this single-group pretest-posttest study, 10 children with ASD (mean age, 47.9 ± 8.3 months), including 7 boys and 3 girls, participated. Participants received 16 intervention sessions in 8 weeks. The combined intervention consisted of various methods derived from contemporary behaviorism, schemas, sociocultural, and event representation approaches. The MacArthur-Bates Communicative Development Inventory 1 (Infant form) assessed early lexical development before and after intervention and after a 2-month follow-up. The Friedman test was used to analyze the data, and pairwise comparisons were performed with the Will-Coxon test. Cohen's d was used to investigate the effect sizes. Results: Significant increases in expressive vocabulary (P < 0.001) and receptive language (P < 0.001) were seen after the end of the intervention and at the follow-up (P = 0.005). Large effect sizes were found for expressive vocabulary (d = 3.7) and receptive vocabulary (d = 2.17). Conclusion: This study suggests that the combination of intervention based contemporary behaviorism, schemas, sociocultural, and event representation approaches improved receptive and expressive vocabulary in minimally verbal children with ASD.
RESUMEN
OBJECTIVE: This systematic review and meta-analysis aimed to estimate the prevalence of voice disorders and related factors in university professors. METHODS: In this systematic review, Medline, Scopus, Embase, Cochrane Library, Eric, ProQuest, Magiran, Scientific Information Database and IranDoc databases were searched. The search was limited to January 1990 and May 2020. The inclusion criteria were reports of the prevalence of voice disorders in university professors and original studies in English and Persian languages. The exclusion criteria were studies assessing voice disorders in school or music teachers; the full-text not available; and case studies, conference papers, and review studies. All eligible studies were selected and critically appraised using the Joanna Briggs Institute checklist. Finally, a meta-analysis was performed using STATA 16.0 statistical software. RESULTS: The preliminary search yielded 1251 articles and 18 of which met the eligibility criteria. The overall prevalence of voice disorders in university professors was 41% (Pooled prevalence: 0.41, 95% CI: 0.34-0.49, P-value < 0.001). Country-based analysis showed that the highest prevalence of voice disorders among university professors was in Iran 69% (Pooled prevalence: 0.69, 95% CI: 0.62-0.76) and the lowest was in China 20% (Pooled prevalence: 0.20, CI: 0.14-0.27). Among 4037 university professors, caffeine consumption was the most frequent related factor (87%) and dry throat was the most frequent symptom (46%). CONCLUSIONS: The present study yielded about 41% of the professors had voice disorders. Among the influential habits, caffeine consumption and among the symptoms, dry throat were very common in university professors. Due to the cross-sectional nature of our studies, we were not able to perform further analyses on the risk factors for voice disorders. Therefore, more longitudinal surveys are needed for reaching a more reliable and deep view into the development of voice disorders.
RESUMEN
The eating assessment tool (EAT-10) is a self-reported questionnaire to assess the patient's perception of swallowing difficulties. The aim of this study was to cross-culturally adapt and determine validity and reliability of the Persian version of the EAT-10 (P-EAT-10) in patients with oropharyngeal dysphagia. The EAT-10 was translated into Persian language and cross-culturally adapted. One hundred patients with dysphagia (mean age ± SD = 44.44 ± 14.69 years) participated. The test-retest reliability (time interval = 7 days) was assessed in 50 patients. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable change (SDC) were analyzed. The Persian version of functional oral intake scale (FOIS-P) was also recorded to assess construct validity. One hundred healthy subjects completed the P-EAT-10 for clinical validity. Factor analysis was performed to determine the P-EAT-10 structure. There were no missing responses and floor or ceiling effects. Internal consistency was high (Cronbach's α 0.91). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.62-0.83). The test-retest reliability was excellent [(ICC)agreement 0.96]. The SEM and SDC were 2.61 and 7.23, respectively. Construct validity was confirmed by a significant correlation between the P-EAT-10 and FOIS-P scores (r = 0.84). Clinical validity was supported by a significant discrimination between patients and healthy subjects (t = 29.97, P < 0.001). Factor analysis indicated 2 components for the P-EAT-10. The P-EAT-10 is a valid and reliable tool and can be used in clinic and research for the assessment of oropharyngeal dysphagia in Persian-speaking patients.

BACKGROUND: Muscle tension dysphonia (MTD) is common in traditional singers and can lead to serious complications, but there is inconclusive evidence about how MTD should be treated in singers as professional voice users. This study was conducted to investigate the effects of breathing exercises combined with manual therapy versus breathing exercises and manual therapy on voice quality in traditional singers suffering from MTD. METHODS: In this blinded randomized clinical trial, 60 patients with MTD were randomly allocated to four groups: (1) breathing exercises, (2) manual therapy, (3) combined intervention (CI) and (4) control. Patients received treatments for 13 sessions, once per week. Treatment effects were assessed in terms of primary outcome measures: (1) breathing performance, measured by maximum phonation time (MPT) and (2) laryngeal function, measured by Stroboscopy Evaluation Rating Form (SERF). Secondary outcome measure was patient's self-perceived voice handicap, measured by Persian version of Singing Voice Handicap Index (SVHIp). All outcome variables were measured before and after treatment. The between group comparisons on MPT and SVHIp score were investigated using analysis of covariance (ANCOVA). The Kruskal-Wallis non-parametric test was used for between group comparisons of SERF items. RESULTS: Three treatment groups had improved regarding breathing performance, laryngeal function and voice handicap over the time (P < 0.01). The improvements achieved in all outcomes were significantly greater in the CI group than those of the breathing exercises, manual therapy and control groups. CONCLUSIONS: This randomized controlled trial showed that the combination of breathing exercises and manual therapy significantly improved the laryngeal function, breathing performance and voice handicap in traditional singers suffering from MTD. TRIAL REGISTRATION: IRCT2015102524686N1.

PURPOSE: Feeding problems are common in premature infants (PIs) and may lead to negative consequences such as malnutrition, dehydration, excessive weight loss, as well as developmental and psychological deficits. Moreover, they are associated with increased length of hospital stay/cost. There is not enough evidence on how feeding problems should be treated in PIs. The goal of this study was to investigate the effects of non-nutritive sucking combined with oral motor stimulation and oral support on feeding performance in PIs. METHODS: A single-blind randomized clinical trial was performed on 44 PIs with feeding problems. Patients were randomly categorized into two groups: (1) combined intervention (CI) and (2) non-nutritive sucking (NNS). The CI group received NNS, oral motor stimulation and oral support simultaneously. Infants in both groups received 14 treatment sessions for 14 consecutive days. The Preterm Oral Feeding Readiness Assessment Scale (POFRAS) was used as the primary outcome measure. Weight, volume of milk intake, time to achieve full oral feeding, and length of hospital stay were secondary outcome measures. All measures were assessed before treatment, after the 7th session, after the 14th session, and after 7 days after the end of treatment. RESULTS: Both groups improved in all outcome measures across time (Pâ<â0.001). The improvements in the POFRAS, volume of milk intake, and time to achieve full oral feeding were significantly greater in the CI group than the NNS group (Pâ<â0.001). The improvements attained in weight and length of hospital stay were not significantly different between the CI and NNS groups (Pâ>â0.05). Large effect sizes were found for POFRAS score in both CI (dâ=â3.98) and NNS (dâ=â2.19) groups. CONCLUSION: The current study showed that the combined intervention including NNS, oral motor stimulation, and oral support significantly improved the feeding performance in PIs.

Dysphagia after multiple sclerosis (MS) is a common disabling symptom which can lead to serious complications. Regular screening and assessment of dysphagia in patients with MS are important. Using valid and reliable instruments to measure dysphagia in MS patients is a crucial component in clinical practice and of research quality. There are various strategies to diagnose and assess the dysphagia in patients with MS. Screening strategies are for early diagnosis of the dysphagia. Clinical, non-instrumental strategies are used to verify the presence and to determine the severity and cause of dysphagia. Instrumental strategies are complementary to clinical examination to provide objective data on the various aspects of swallowing dysfunctions. This review revealed a few validated tools for dysphagia assessment in MS. The Dysphagia in Multiple Sclerosis Questionnaire (DYMUS) and the Mann Assessment of Swallowing Ability (MASA) are the only validated MS-specific dysphagia tools. Further development of valid and reliable MS-specific screening and assessment tools that can be administered rapidly and scored easily to detect dysphagia and evaluate clinical outcomes in adults with MS is imperative. Until then, validation and metric evaluation of the screening and assessment tools currently available are required.
RESUMEN
OBJECTIVES: The purpose of the present study was to investigate the effect of Voice Therapy (VT) with and without Transcutaneous Electrical Nerve Stimulation (TENS) in women with Muscle Tension Dysphonia (MTD). METHODS: A total of 20 women with MTD participated in the study. Participants underwent evaluation of auditory-perceptual assessment, acoustic voice analysis, Vocal Tract Discomfort (VTD), and musculoskeletal pain before and after the treatment. The participants were divided into two groups: (1) TENSâ¯+â¯VT group (10 participants) and (2) VT group (10 participants). Both groups received 10 sessions of treatment, twice a week, each lasting 50 minutes. The statistical analysis was performed using Wilcoxon signed ranked and Mann-Whitney U tests (P < 0.05). RESULTS: After VT, significant improvements were observed in all auditory-perceptual parameters and all VTD items except for the tickling frequency and severity. The VT caused significant reduction in the frequency of pain in anterior neck, posterior neck, and the larynx. Also, VT resulted in a significant reduction in pain intensity only in the larynx. After VTâ¯+â¯TENS, significant improvements were observed in all auditory-perceptual parameters, shimmer, and all VTD items. Moreover, the VTâ¯+â¯TENS led to a significant decrease in the frequency and intensity of pain in anterior neck, posterior neck, the larynx, masseters, shoulders, and upper back. The findings of between-group comparison after treatment showed significantly more reduction in the frequency (dry and pain items) and severity (tight and pain items) of the VTD in VTâ¯+â¯TENS group compared with VT group. Regarding the musculoskeletal pain, significantly more reduction in the frequency and intensity of pain in anterior neck and the larynx was observed in VTâ¯+â¯TENS group compared with VT group. CONCLUSIONS: The VT and VTâ¯+â¯TENS could lead to positive outcomes in auditory perceptual assessment, acoustic voice analysis, the VTD, and assessment of musculoskeletal pain. In some items of frequency and severity of VTD scale and assessment of musculoskeletal pain, VTâ¯+â¯TENS also produced better results compared with VT. As a result, TENS was recommended as a complementary therapy for patients with MTD, especially when these patients had more complaints about VTD and musculoskeletal pain.

INTRODUCTION: The aim of the present study was to investigate the immediate effect of the application of high-frequency Transcutaneous electrical nerve stimulation (TENS) in muscle tension dysphonia (MTD) patients with the pain complaint. MATERIALS AND METHODS: Thirty patients with MTD, 10 men and 20 women with a mean age of 36.40 ± 5.76 years, participated in the study. The patients were randomized into two groups: (1) Treatment group (TENS) (10 women and 5 men) and (2) Sham TENS group (10 women and 5 men). The treatment group (TENS) received a unique 20-minute session of high-frequency TENS. The sham TENS group was treated in the same condition as the treatment group and received a unique 20-minute session of high-frequency TENS, but no stimulation was given. Auditory-perceptual assessments, acoustic voice analysis, vocal tract discomfort (VTD), and musculoskeletal pain were used to compare the patients pre- and post-treatment. RESULTS: There was a significant improvement in the asthenia parameter of auditory-perceptual assessment in the TENS group. This improvement in asthenia was significant when comparing the TENS group with the sham TENS group. These differences in the asthenia were not significant after using Holm-Bonferroni correction. A comparison of the VTD before and after the TENS application showed there was a significant reduction in the severity of the symptoms (burning, tight, dry, pain, tickling, sore, irritable, and lump in the throat). When comparing the TENS group with the sham TENS group, improvements in burn, tight, dry, pain, and irritable items of VTD were observed. However, after applying the Holm-Bonferroni correction, only reductions in dry and pain items remain significantly different between the groups. After the TENS application, the pain intensity was significantly reduced in the anterior and posterior neck, larynx, submandibular, masseter, temporal region, and upper back. After applying the Holm-Bonferroni correction, pain intensity reduction was significant in the anterior neck and larynx. When comparing the TENS group with the sham TENS group, pain intensity was reduced significantly in the larynx of the TENS group. This difference between the two groups was not significant after using Holm-Bonferroni correction. The pain and VTD assessments in the present study were performed using valid and reliable self-reported scales (NMSQ-E and VTD). CONCLUSION: High-frequency TENS can be used in the voice treatment program of patients with MTD. MTD patients with pain complaint reported that their vocal tract discomfort and pain were decreased following the high-frequency TENS. Notably, these positive effects were obtained after a single session of high-frequency TENS application.

INTRODUCTION: Swallowing disorder or dysphagia is a common complication after conventional total thyroidectomy. Traditional dysphagia therapy (TDT) has long been a routine rehabilitation program for patients with dysphagia; however, there is no evidence to support the efficacy of this approach in patients with post-thyroidectomy dysphagia. Regarding this, the purpose of the current study was to explore the effectiveness of TDT in swallowing dysfunction in patients suffering from post-thyroidectomy dysphagia. MATERIALS AND METHODS: This pilot clinical trial was conducted on 21 patients with post-thyroidectomy dysphagia. The study population was randomly assigned into two groups of TDT and control. The patients in the TDT group received 18 treatment sessions for 6 weeks, 3 times a week. The Swallowing Impairment Score (SIS-6), Functional Oral Intake Scale (FOIS), and Persian Dysphagia Handicap Index (P-DHI) were the outcome measures. The outcome variables were assessed at the baseline, at the end of the treatment, and after a 6-week follow-up. The main effects of time and group and their interaction effect on SIS-6 and P-DHI scores were examined using repeated measures ANOVA. In addition, the intergroup comparison in terms of the FOIS score was analyzed using the Mann-Whitney U test. The Cohen's d effect size was also measured to ascertain the effects of the treatment. RESULTS: According to the results, the TDT group showed a significant improvement in the SIS-6, FOIS and P-DHI scores over time (P<0.001). The results also revealed that the interaction effect of time and group was significant on SIS-6 and P-DHI scores (P<0.001). In addition, effect sizes on SIS-6, FOIS, and P-DHI scores were large in the TDT group. CONCLUSION: This study suggested that TDT could improve the swallowing dysfunction in the patients suffering from post-thyroidectomy dysphagia. As the results indicated, the improvements persisted 6 weeks after the end of TDT.
RESUMEN
INTRODUCTION: Patients with muscle tension dysphonia (MTD) suffer from several physical discomforts in their vocal tract. However, few studies have examined the effects of voice therapy (VT) on the vocal tract discomfort (VTD) in patients with voice disorders. Therefore, the aim of the present study was to investigate the effects of VT on the VTD in patients with MTD. MATERIALS AND METHODS: This study was carried out on 25 subjects with MTD, including 5 men and 20 women, with the mean age of 37.20±5.70 years. The participants underwent 10 consecutive sessions of VT twice a week. The acoustic voice analysis, auditory-perceptual assessment, and the Persian version of the vocal tract discomfort (VTDp) scale were used to compare the pre- and post-treatment results. RESULTS: After VT, significant improvements were observed in the acoustic characteristics, including jitter, shimmer, and harmonics-to-noise ratio (P<0.05). Regarding the auditory-perceptual assessment, a significant reduction was noticed in the overall severity, roughness, and breathiness (P<0.05). Moreover, VT led to a significant reduction in all the items of the VTDp, including burn, tightness, dryness, pain, tickling, soreness, irritability, and lump in the throat, after VT in both frequency and severity sections of the VTDp scale (P<0.05). CONCLUSION: The results of the present study showed that VT can be effective in reducing the frequency and severity of the VTD in patients with MTD in addition to improving voice quality.
RESUMEN
BACKGROUND: Dysphagia is common following Multiple Sclerosis (MS) and is associated with significant morbidity and mortality. The current rehabilitation program to swallowing therapy is Traditional Dysphagia Therapy (TDT), but there is a dearth of evidence about its effectiveness in MS patients. OBJECTIVES: This study was aimed to determine the effects of the TDT on the swallowing function in MS patients with dysphagia. METHODS: A pilot double blind randomized clinical trial was carried out on 20 patients with MS. Patients were randomly divided into experimental group (TDT) comprising sensorimotor exercises and swallowing maneuvers, and Usual Care (UC) comprising diet prescription and postural changes. Patients in both groups received treatments for 6 weeks, 18 treatment sessions, 3 times per week, every other day. The Mann Assessment of Swallowing Ability (MASA) was the main outcome measure. The swallowing ability was assessed before treatment (T0), after the end of 9th session (T1), after the end of 18th session (T2), and after 6 weeks follow-up (T3). Penetration-Aspiration Scale (PAS) and Pharyngeal Residue Rating Scale (PRRS) as secondary outcome measures were applied at T0 and T2. RESULTS: Both groups had improved regarding MASA, PAS and PRRS scores over the time (Pâ¯<â¯0.001). The improvements achieved in all outcomes were significantly greater in the TDT group than those of the UC group. The Main effect of the Timeâ¯×â¯Group interaction was significant for MASA score (Pâ¯<â¯0.001). The large effect sizes were found for MASA score in both the TDT (dâ¯=â¯3.91) and the UC (dâ¯=â¯1.11) groups. CONCLUSIONS: This pilot randomized controlled trial showed that the TDT significantly improved the swallowing function of the MS patients with dysphagia.

Dysphagia following stroke is common and can lead to severe complications such as aspiration pneumonia, but there is inconclusive evidence on how poststroke dysphagia should be treated. This study aimed to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) combined with the traditional dysphagia therapy on the swallowing function in patients with poststroke dysphagia. In this pilot double-blind randomized clinical trial, 18 patients with poststroke dysphagia were allocated randomly to three groups: (i) traditional dysphagia therapy, (ii) rTMS, and (iii) combined intervention. Patients received traditional dysphagia therapy for 18 treatment sessions three times per week. The inhibitory rTMS was applied to the intact cerebral hemisphere at 1 Hz with a train of 1200 for 5 consecutive days. The patients in the combined intervention group received traditional dysphagia therapy and rTMS simultaneously. The Mann Assessment of Swallowing Ability (MASA) and Functional Oral Intake Scale were performed before treatment, after the end of the fifth session, after the end of the 10th session, after the end of the 15th session, and after the end of the 18th session. All groups had improved on MASA and Functional Oral Intake Scale scores over time (P<0.01). The improvements achieved in all outcomes were significantly greater in the combined intervention group than those of the traditional dysphagia therapy and rTMS groups. The large effect sizes were found for the MASA score in all groups: traditional dysphagia therapy group (d = 3.57), rTMS group (d = 2.67), and combined intervention group (d = 3.87). This pilot randomized-controlled trial showed that the combination of rTMS and traditional dysphagia therapy significantly improved swallowing function in patients with poststroke dysphagia.

Background: Dysphagia is the most prevalent sign of multiple sclerosis (MS) which can reduce the quality of life and augment mortality in the final stages of MS. We presented a systematic review to estimate the prevalence of dysphagia in general and separately for each evaluation method (subjective and objective), and to analyze the causes of this rampant disease. Methods: Cross-sectional and prospective cohort studies were reviewed and scientific proofs were evaluated consistent with the pre-specified levels of certainty. Results: Twenty-two articles entered the meta-analysis phase; the estimation of the general prevalence of dysphagia in MS-affected patients was 43.33% related to all the 22 studies. Moreover, the estimate of the prevalence via the subjective (16 studies) and objective (6 studies) methods were 37.21% and 58.47%, respectively. Conclusion: This study obtained the prevalence rate of dysphagia in patients affected by MS globally, yet there was infinite statistical society and limited methodological quality. Thus, more extensive studies are required for a better understanding of the global epidemiology regarding dysphagia in MS.
RESUMEN
OBJECTIVES: The aim of the present systematic review was to investigate the nonmedical treatments of vocal fold nodules (VFNs). STUDY DESIGN: The present study is a systematic review. METHODS: The following electronic databases were searched from inception until August 2016: PubMed, Scopus, ScienceDirect, Ovid, ISI (Web of Sciences), Cochrane, PsychINFO, The Cochrane Central Register of Controlled Trials, and Google Scholar. Reference lists of included articles were evaluated for additional data. Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were used to carry out and report the review. The methodological quality of the articles included was evaluated using the Physiotherapy Evidence Database scale. Due to the heterogeneity of the studies, a narrative synthesis of the evidence was performed to summarize the evidence. RESULTS: Out of 2,099 records identified, 21 articles met the inclusion criteria and thus were included in the review. The studies investigated in the present review were different in terms of study design, participant characteristics, types of assessments and treatments, and treatment delivery. However, nonmedical treatments of VFNs were found to be successful in improving vocal quality, decreasing VFN sizes, and resolving these nodules. CONCLUSIONS: The results of the present review could provide primary evidence related to the effectiveness of nonmedical treatment of VFNs. Yet further studies with a high level of evidence, a rigorous methodological quality, and long-term follow-up evaluations are required to make stronger claims.

INTRODUCTION: Perceptual and acoustic analyses are essential tools that help voice therapists comprehensively assess voice quality. While perceptual evaluations are subjective and are influenced by external and culturally driven factors, acoustic analysis is an objective and reliable means of evaluating voice. The goals of this study were (1) to determine which acoustic parameters were predicted by perceptual voice quality and (2) to assess the effect of a short period of training on the reliability of perceptual voice analyses for Persian speakers. METHOD: This was a cross-sectional study. Subjects were 20 patients with various voice disorders. Voice samples were obtained during text reading and /a/ prolongation. Fifteen expert voice clinicians completed perceptual evaluations on voice samples using the Grade, Roughness, Breathiness, Asthenia, and Strain scale. We repeated this process after a short period of perceptual voice evaluation training. Acoustic analysis was completed using the Praat program. We used the intraclass correlation coefficient (ICC) for reliability measurement of the perceptual evaluation results and ordinal regression procedures to analyze all data. Significance level was set at P < 0.05. RESULTS: Both intrarater and interrater reliability increased after training, for all five parameters. The ICC for grade increased to 0.95 after training. Grade and roughness significantly predicted fundamental frequency (F0) (P = 0.021 and P = 0.030, respectively) and harmonic-to-noise ratio (HNR) (P = 0.019 and P = 0.016, respectively). Breathiness significantly predicted shimmer (P = 0.013). CONCLUSION: Training had a positive effect and increased the reliability of perceptual voice evaluation. For Persian listeners, changes in F0, increases in HNR, and shimmer were perceptually associated with poor voice quality.

The aim of this study was to translate and cross-culturally adapt the swallowing quality-of-life questionnaire (SWAL-QOL) to Persian language and to determine validity and reliability of the Persian version of the swallow quality-of-life questionnaire (PSWAL-QOL) in the patients with oropharyngeal dysphagia.The cross-sectional survey was designed to translate and cross-culturally adapt SWAL-QOL to Persian language following steps recommended in guideline. A total of 142 patients with dysphagia (mean ageâ=â56.7â±â12.22 years) were selected by non-probability consecutive sampling method to evaluate construct validity and internal consistency. Thirty patients with dysphagia were completed the PSWAL-QOL 2 weeks later for test-retest reliability.The PSWAL-QOL was favorably accepted with no missing items. The floor effect was ranged 0% to 21% and ceiling effect was ranged 0% to 16%. The construct validity was established via exploratory factor analysis. Internal consistency was confirmed with Cronbach α >0.7 for all scales except eating duration (αâ=â0.68). The test-retest reliability was excellent with intraclass correlation coefficient (ICC) ≥0.75 for all scales.The SWAL-QOL was cross-culturally adapted to Persian and demonstrated to be a valid and reliable self-report questionnaire to measure the impact of dysphagia on the quality-of-life in the Persian patients with oropharyngeal dysphagia.

Background: Dysphagia is frequently observed in patients with multiple sclerosis (MS). Dysphagia and its complications are common causes of morbidity and mortality in final stages of MS disease. This study aimed at determining the prevalence of dysphagia in Iranian patients with MS and identifying predictors associated with dysphagia. Methods: A total of 230 MS patients were enrolled in this cross-sectional study. Dysphagia was evaluated using Mann Assessment of Swallowing Ability (MASA). Demographic characteristics (age and gender), duration of the disease, disease course, and Expanded Disability Status Scale (EDSS) were recorded for all participants. Results: In total, dysphagia was found in 85 participants (37%) with mild to severe dysphagia (mild 50.6%; moderate 29.4%; and severe 20%). The logistic regression model demonstrated that disability status in EDSS (OR= 2.1; 95% CI 0.5-1.2) and disease duration (OR= 2.3; 95% CI 0.4-1.1) predicts a high risk for dysphagia in MS patients. Conclusion: Dysphagia is prevalent in Iranian patients with MS. Disability level and disease duration are significant predictors of dysphagia after MS.
RESUMEN
BACKGROUND: Post-stroke dysphagia is common and is associated with the development of pneumonia. To investigate the effects of repetitive transcranial magnetic stimulation (rTMS) combined with traditional dysphagia therapy (TDT) on swallowing function in patients with post-stroke dysphagia. METHODS: In this single-subject study, four patients with dysphagia post-stroke included. The patients received the rTMS applied to the intact cerebral hemisphere at 1 Hz with train of 1200 for 5 consecutive days combined with TDT 3 days per week for 6 weeks. The main outcome measure was the Mann Assessment of Swallowing Ability (MASA). Measurements were taken before, after the end of 5(th), 10(th), 15(th) treatment sessions, and after the end of the treatment (18(th) session). RESULTS: The MASA scores improved in all patients following treatment. The maximum and minimum change in level between the baseline phase and treatment phase was +84 and +36. The greatest percentage improvement was observed after 5(th) treatment sessions ranging between 11 and 35%. The treatment trend was upward shown by the directions of the slopes indicated by positive values (+9.1-+20.7). The dysphagia was resolved after 10(th) treatment session in all participants. The aspiration resolved in two participants after the 5(th) treatment session and resolved in another 2 participants after the 10(th) treatment session. CONCLUSION: The combination therapy of rTMS plus TDT improved swallowing function in patients with post-stroke dysphagia. Further research with a larger sample size is recommended.
