Voice Therapy Efficacy in Pediatric Professional Voice Users With Vocal Fold Nodules: A Preliminary Study

Vocal fold nodules are the most common diagnosis in children with dysphonia. It is also frequently seen in professional voice users who uses their voice as an occupational tool. It can be caused by excessive or hyperfunctional use of the voice leading to phonotrauma. Children who learn the Quran by heart and recite it use their voices excessively and it causes voice problems. Voice therapy can play an important role in regulating phonotraumatic behaviors and improving voice quality, thereby replacing surgical intervention in some cases or acting as a complementary therapy to improve eventual therapeutic outcomes. Our aim was to find the efficacy of group voice therapy compared to individual voice therapy in a group of pediatric professional voice users who go to the same religious school. To determine group therapy efficacy, 24 students between the age of nine and 14, were evaluated and 16 of them had vocal fold nodules. Therapy sessions started with 16 students whose ages ranged from nine to 14 with a mean of 11,3 ± 1,4 years old. They were divided into two groups: group and individual therapy groups. Treatment comprised both direct and indirect voice therapy and lasted 6 weeks. Three of the participants were dropped out due to absence. Pre- and post-therapy measures were collected from 13 participants using perceptual evaluation, videostroboscopy measures, and the pediatric voice handicap index to determine the efficacy of group voice therapy compared to individual voice therapy with a group of pediatric professional voice users with vocal fold nodules. As a result of our study, eight of participants were found to have healthy vocal folds; the s/z ratio was significantly different between groups and within group therapy participants pre- and post-therapy. No significant difference was found in other parameters; except noise harmonic ratio (NHR). NHR was found significantly different between pre- and post-therapy when individual therapy and group therapy were compared. Although both treatments were shown to be beneficial in the management of vocal fold nodules, individual therapy was found to be somewhat more effective. In pediatric voice therapy, group therapy is an effective option to reach out to more individuals with voice disorders. It can be beneficial for time management and cost effectiveness in voice therapy.

Immediate Effects of Combining Kinesio Tape with Voice Therapy in Patients with Muscle Tension Dysphonia

The present study investigated the immediate effect of adding Kinesio taping along with voice therapy for the treatment of muscle tension dysphonia patients. Twenty patients with primary muscle tension dysphonia (MTD) (12 males and 8 females) with a mean age of 36.95 ± 9.58 years participated in the study. Participants were assigned to two groups: one group (6 males and 4 females) received only traditional voice therapy (VT) and the other group (6 males and 4 females) received Kinesio taping (KT) and voice therapy (VT). The VT group received laryngeal manual therapy (LMT) (for 15 minutes) and voice therapy techniques including humming, chewing, and yawn-sigh (for 15 minutes). The VT+KT group received both KT and the same VT as the first group. KT was applied to the sternocleidomastoid, infralaryngeal, and supralaryngeal muscles of the neck. Auditory-perceptual assessments using CAPE-V, acoustic voice analysis, and assessments of vocal tract discomfort and pain were used to evaluate the effects of a single treatment session. The Wilcoxon and Mann-Whitney U tests were used for data analysis. The results of within-group comparison of the auditory-perceptual assessment (overall severity, roughness, breathiness, and strain) in both sustained vowels and connected speech tasks showed a significant reduction in all mentioned items in both groups (P < 0.05). Acoustic voice analysis showed significant improvement of HNR in the KT+VT group for both sustained vowels and connected speech tasks, and significant improvement of jitter in the VT group for sustained vowels (P < 0.05). Regarding vocal tract discomfort, the symptom of tightness in the KT+VT group, irritability and pain in the VT group, and the overall score of vocal tract discomfort in both groups, significantly decreased (P < 0.05). A significant decrease in pain severity in the front of the neck, throat, and larynx was reported by MTD patients in both groups (P < 0.05). Between-group comparisons indicated a significant difference only in the pain item of the VTD scale (P < 0.05) with greater pain decrease for the VT group. Comparison of the mean of differences showed that the VT group reduced irritability more than the KT+VT group (P < 0.05). The present study showed that voice therapy with and without Kinesio taping can improve patients' voice quality (auditory-perceptual and acoustic voice analysis) and reduce vocal tract discomfort and pain in MTD patients after one therapy session. Moreover, MTD patients treated with KT+VT did not experience more significant improvements compared to those treated with VT alone. More studies in this area are recommended to better determine the effects of KT in MTD patients especially for long term effects of KT.

Surgical and Non-Surgical Treatment Outcome Assessed by Voice Handicap Index of Patients with Vocal Fold Nodule

Background: Vocal nodules are a frequently occurring type of laryngeal disorder. Vocal fold nodules are usually bilateral swellings of variable size (&lt; 3mm) found at the mid-part of the membranous vocal cords. Vocal abuse, misuse and overuse are frequently claimed to be the causes of vocal nodules and mostly affect professional voice users. It has important public health implications and impact on patient quality of life (QoL). Voice handicap index (VHI) is an important tool for quality of life assessment and outcome of intervention in voice disordered patients.&#x0D; Objective: To compare the outcome of Voice handicap index (VHI) score after surgical and non-surgical intervention of vocal cord nodule.&#x0D; Methods: In this prospective study 30 patients with vocal nodules refractory to the first session of voice therapy were diagnosed by fiber optic laryngoscopy. After simple random allocation management was done either by voice therapy or surgery. VHI (Voice Handicap Index) was applied as outcome measures for assessing the efficiency of intervention between surgical and non-surgical groups.&#x0D; Results: The mean value of Voice handicap index total (VHIt) was 54.40 (± 8.56) before voice therapy which significantly changed to 25.80 (± 6.23) after voice therapy in non-surgical group(n2).&#x0D; Bangladesh J Otorhinolaryngol 2022; 28(1): 29-36

Improvement in Work Productivity After Group Voice Therapy in Professional Voice Users

A disordered voice may significantly impair the ability of workers to perform optimally on the job, especially those classified as professional voice users (PVU). Voice therapy is a common treatment option for voice disorders, but there are few studies demonstrating its effect on work productivity. The objective of this study was to evaluate the change in work productivity in PVU after group voice therapy. Prospective cohort study SETTING: Academic Voice Center METHODS: PVUs whose primary treatment for their voice disorder was voice therapy were recruited. Participants completed a 7-week group voice therapy course from January 2018 to December 2020. Participants completed the validated Work Productivity and Activity Impairment questionnaire (WPAI) which measured presenteeism (on the job work productivity impairment) and absenteeism (time missed from work), general self-efficacy scale (GSES), and Voice handicap index -10 (VHI-10) before and after group voice therapy. Changes in scores before and after therapy were compared using a Wilcoxon Signed-Rank test. Twenty-seven PVU were recruited; 25 had complete data (100% female, mean age 45.4 years, 68% teachers). Presenteeism (SD) decreased from 72.0% (23.3) to 36.8% (24.8), which represented a significant improvement of 35.2% (27.8) [95% CI 21.7-38.7; P < 0.001]. Activity impairment decreased from 48.4% (32.0) to 25.6% (23.8), which represented a significant improvement of 22.8% (26.5) [95% CI 20.7-37.0; P < 0.00]. There was no change in absenteeism (P = 0.27). Patients had high mean GSES of 34.4 (3.7) and abnormal mean VHI-10 of 18.2 (7.2). Changes in VHI-10 and GSES were not significant. PVU had an improvement in work productivity that was largely represented by decreased presenteeism after completing group voice therapy.

Early voice therapy for unilateral vocal fold paralysis improves subglottal pressure and glottal closure.

In cases of unilateral vocal fold paralysis (UVFP), voice disorders caused by glottic insufficiency can lead to a considerable reduction in the patient's quality of life. Voice therapy (VT) is an effective treatment that must be started early after the onset of vocal fold paralysis. This study examined the effect of early VT for patients with UVFP occurring after esophagectomy. Patients who had residual UVFP at 1month postoperatively after esophagectomy for esophageal cancer between November 2014 and March 2017 were evaluated. Seventeen patients were divided into the VT group (n=6) and non-VT group (n=11). We compared these two groups and retrospectively examined the effect of early VT. The study endpoints included aerodynamic tests, laryngeal endoscopy, laryngeal stroboscopy, and glottal closure. All of these evaluations were performed at preoperatively and at 1 and 3months postoperatively. Subglottal pressure reduced notably in the VT group, and both the mean flow rate and maximum phonation time tended to improve after VT. Conversely, there were no significant differences in MFR and MPT in the non-VT group. Furthermore, although UVFP remained after VT, we achieved glottal closure for all three patients. Conversely, only two of the six patients with glottic insufficiency in the non-VT group achieved glottal closure. VT may be effective for improving impaired vocal function in patients with UVFP. It is reasonable to expect that VT can be initiated 1month after the onset of vocal fold paralysis.

Coverage for Gender-Affirming Voice Surgery and Therapy for Transgender Individuals.

To determine insurance coverage for gender-affirming surgery and voice therapy for individuals who seek to align their voice with their gender identity, and to analyze differences based on state-by-state transgender equality. Cross-sectional study. Policies from the top three commercial insurers per state in 2019 were reviewed. Coverage status was determined by web-based search, telephone interviews, and email inquiries. A state-by-state equality score was calculated based on the number of laws and policies relating to the transgender community. Correlation between number of preauthorized procedures and state equality scores was assessed. Of the 150 insurance companies reviewed, only four (2.7%) held favorable policies, whereas 113 (75.8%) provided no coverage. Endoscopic surgery, open surgery, individual voice therapy, and group voice therapy interventions were equally excluded (n = 93, 62.4%). Coverage was not correlated with laws driving transgender equality (P = .782). Gender-affirming voice interventions are seldom covered by commercial insurance companies. Despite established medical necessity and years of experience in practice, gender-affirming interventions for voice have not yet been fully considered by third-party payors. Further investigation regarding cost-effectiveness and treatment efficacy is warranted to improve insurance coverage of voice-related gender-affirming care. NA Laryngoscope, 131:E896-E902, 2021.

The value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis

Objective: To investigate the value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis (UVCP). Methods: From May 2015 to April 2018, 51 patients with UVCP and 59 healthy controls in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, were involved in this research retrospectively. The UVCP patients were diagnosed with stroboscopic laryngoscopy. The minimum glottal area (MGA) was calculated by KIPS software when the people were pronouncing/i:/. The fundamental frequency (F0), Jitter, Shimmer and NHR were detected by CSL4500 multiple acoustic voice analyzer. Results: MGA of UVCP patients was much higher than that of healthy control (male: 433.68±64.52 vs. 294.41±51.82, t=9.23, P=0.000; female: 498.80±73.42 vs. 302.03±76.54, t=13.21, P=0.000), which meaned vocal cord insufficiency.After voice therapy, MGA reduced significantly (male: 288.48±55.09, female: 258.22±57.17, t=24.41 and 31.22, P=0.000 vs. pre-therapy). MGA of untreated patients decreased in varying degrees. Compared with the voice therapy group, the MGA decreased in a significantly lower extent (24.25±22.91 vs. 188.31±54.37, t=8.97, P=0.000). The F0, Jitter, Shimmer and NHR raised significantly in UVCP patients group (P=0.000 vs. healthy control group), and they were reduced by voice therapy (all P<0.05). Each of the four acoustic parameters was relative with MGA, r=0.551, 0.867, 0.853 and 0.875 in turn, P=0.001, 0.000, 0.000, and 0.000. Conclusion: MGA and acoustic parameters can reflect the acoustic features of UVCP patients, which are useful tools in the UVCP assessment and voice therapy.

Group Voice Therapy Reduces Anxiety in Patients With Dysphonia

To evaluate the impact of group therapy in patients with dysphonia, as well as to verify the correlation between vocal symptoms and levels of anxiety. The study was composed of 52 patients subdivided into two groups, named the Experimental Group (EG) with 28 volunteers and the Control Group (CG) with 24 volunteers. Anxiety and voice protocols were used for data collection. The State-Trait Anxiety Inventory (STAI) was used to measure trait levels of anxiety that after collection were categorized according to the variation in scores value: low anxiety (20-40 points); average anxiety (40-60 points); high anxiety (60-80 points). In addition, the Voice Symptom Scale (VoiSS) was used for voice assessment. Inferential statistical analysis from the Student's t test for paired and independent data, in order to compare the average scores of STAI trait levels and VoiSS domains of the pre- and postmoments, intra- and intergroups, EG and CG, respectively. For that purpose, the program Statistical Package for Social Sciences (SPSS) was used. Half of the patients in the survey presented an average trait level of anxiety. Regarding the EG, there was a significant reduction of state anxiety when comparing the moments before and after group therapy. There was also a significant reduction in the values of the VoiSS-Total and VoiSS-Physical domains when compared to the pre- and postgroup therapy moments. It was verified the existence of a positive correlation between the levels of anxiety after group therapy and VoiSS-Total, VoiSS-Limitation, and VoiSS-Physical domains. As for the CG, there was an increase in anxiety levels as well as in all domains of the VoiSS scale when compared to the pre- and postmoments. Group voice therapy was effective for a significant reduction of vocal symptoms and anxiety - common conditions in patients with dysphonia. It was possible to perceive the positive correlation between anxiety levels and vocal symptoms.

Transcutaneous Electrical Nerve Stimulation Combined With Voice Therapy in Women With Muscle Tension Dysphonia

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). 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) TENS + 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). 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 VT + TENS, significant improvements were observed in all auditory-perceptual parameters, shimmer, and all VTD items. Moreover, the VT + 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 VT + 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 VT + TENS group compared with VT group. The VT and VT + 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, VT + 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.

Voice Therapy Outcome—A Randomized Clinical Trial Comparing Individual Voice Therapy, Therapy in Group, and Controls Without Therapy

ObjectiveA stumbling-block in voice therapy is how the patient will be able to apply the new voice technique in everyday life. Possibly this generalization process could be facilitated by giving voice therapy in group because of the natural forum for training voice-to-speech early in communication between the patients in a group setting. The aim of the study was to compare treatment results from individual voice therapy and voice therapy in group, at several time points and in comparison to patients with no voice therapy. MethodsA randomized treatment study was performed with 77 consecutive patients diagnosed with a functional voice disorder. Thirty-one patients were randomized to individual and group therapy, respectively, and 15 patients to no therapy. The assessments included standardized voice recording and registration of voice range profile (VRP), answering Voice handicap index (VHI) and visual analogue scales for self-hoarseness and self-vocal fatigue, and perceptual voice evaluation by speech-language pathologist. The assessments were performed before, direct after therapy, and three months later in all groups. The 2 therapy groups were also assessed 12 months after therapy. ResultsAll VHI scores as well as the self-ratings of hoarseness and vocal fatigue, and the perceptual evaluation of voice quality and maximum VRP improved significantly in both therapy groups 3 months after treatment and at 12 months follow-up. There were no significant changes in the control group, with the exception of decreased self-rated hoarseness and increased maximum VRP. Comparisons between treatment groups showed significant larger improvement after group therapy for VHI physical subscale at 12 months, as well as significant lower VHI total score at all measurement sessions and lower subscale scores at 12 months. There were no differences between treatment groups in self-hoarseness or self-vocal fatigue and no difference in perceptual voice quality or VRP. Comparison between controls and treatment groups showed significant larger change in treatment groups from baseline to three months in VHI total and to end of therapy in functional subscale. Treatment groups also showed significant lower scores than controls at each measurement session, for VHI total and physical subscale as well as lower degree of perceptual aberration of voice quality and vocal fatigue, at three months follow-up. ConclusionsThis study shows long-term improvement from behavioral voice therapy, particularly in a group setting. The results indicate the importance of early transfer-to-speech and late posttherapy test to capture whether the goal of voice therapy was fulfilled or not for the patients.

Effect of voice therapy on vocal fold polyp treatment.

To investigate the role of voice therapy (VT) and factors that may affect the response to VT in the treatment of vocal fold polyps, especially as a complementto phonosurgery. Retrospective review of patients with vocal fold polyp undergoing surgery and/or VT in a tertiary medical center. The demographic data, phoniatric history, videolaryngostroboscopic findings, polyp characteristics, VHI-10 and GRB scores, and voice analysis data were recorded before and after the treatment. The patients were grouped as those who had undergone endolaryngeal microsurgery only (Group S), those who had first received VT then undergone surgery due to inadequate VT outcome (Group VTpS), and those who had only undergone VT with a follow-up plan (Group VT). Data were reviewed from 211 (108M, 103F) patients with a mean age of41.3 ± 11years. The improvement in all voice-related variables observed in the S and VTpS groups was significantly greater compared to the VT group despite the degree of improvement achieved in this group. At the end of the treatment period, improvements in G-R-B, VHI-10 and stroboscopy scores were significantly greater in the VTpS group than in the S and VT groups. Voice therapy can improve voice quality to some extent during the treatment of vocal fold polyps. However, VT alone is unsatisfactory compared to surgery alone. Pre-surgical VT can enhance the ultimate success of treatment. A young age, small polyps, and short duration of dysphonia may increase the possibility of benefiting from VT.

Stage of readiness of patients with behavioral dysphonia in pre and post-group voice therapy assessments.

To verify the efficacy of group voice therapy in the stage of readiness and identify which items of the URICA-Voice range are more sensitive to post-therapy change in patients with behavioral dysphonia. An intervention study was conducted on 49 patients with behavioral dysphonia. An eclectic approach to group therapy was implemented over eight sessions, the first and last sessions consisting of assessments. The URICA-Voice range was used to evaluate the stage of readiness at pre- and post-therapy assessments. A descriptive and inferential statistical analysis was implemented for the results. Most participants were female, did not make professional use of voice, and had membranous vocal fold lesions. Most of them were in the Contemplation stage at in both moments, pre- and post-therapy. There was no significant change in the comparison of pre- and post-therapy scores. The majority of patients showed a reduction in the stage of readiness and some advanced to a higher stage. In the comparison of URICA-V range items, seven questions had equal or inferior responses in the post-therapy assessment. There was no statistical difference when comparing the pre- and post-therapy total average score of the URICA-Voice range. There were significant changes in the stage of readiness of patients in pre- and post-group speech therapy assessments.

The Study of Combined Voice Therapy with Intralaryngeal Injection

Background and Objectives Though voice therapy is proven to be effective in academia, treatment results and satisfaction level are inconsistent in clinics. The inconsistency may rise from diverse vocal cords misuse patterns in patient population as they suffer from different diseases or have bad phonation habits. In order to overcome the limitation, we uniformized patients’ vocal cords with injection laryngoplasty prior to voice therapy. The efficacy of voice therapy and consistency in treatment results after injection laryngoplasty were assessed. Materials and Methods Patients diagnosed with vocal nodules were either treated with injection laryngoplasty followed by voice therapy (combined treatment group) or voice therapy only (voice therapy group). Each group consisted of 15 patients. Acoustic measures (jitter, shimmer, NHR), aerodynamic measures (MPT, Psub, MAFR), and subjective auditory conscious measures (K-VHI, K-VRQOL) between two groups were analyzed. Results After treatments, both groups improved in terms of acoustic, aerodynamic, and subjective auditory conscious measures compared to pre-treatment. Combined treatment group had statistically significantly greater improvement in shimmer, P in K-VHI, and PF in K-VRQOL compared to voice therapy group. Conclusion Injection laryngoplasty treatment prior to voice therapy synergizes in treating patients compared to voice therapy only.

Multidimensional Assessment of the Effectiveness of Group Voice Therapy

Group voice therapy has been successfully used in patients with dysphonia, but there is little objectively documented evidence of its effects on voice quality and the self-perception of voice fatigue. The aim of this study was to investigate the effectiveness of group therapy in patients with functional dysphonia and minor anatomic vocal fold pathologies linked by appearance and history to voice use in an objective and multidimensional manner. This is a prospective longitudinal study. Before and after treatment, 34 adult women underwent perceptual voice assessments using the grade of dysphonia, roughness, breathiness, asthenia, and strain (GRBAS) scale, Evaluation Vocale Assistée (EVA) system aerodynamic and acoustic assessments, and maximum phonation time measurements, and made subjective evaluations using the Voice Handicap Index. The pretreatment baseline values of the participants were obtained by means of two examinations separated by an interval of 1 week. The parameters belonging to each main dimension were clustered by means of Z-transformation, and the corresponding Z-scores were analyzed. Group therapy was associated with a statistically significant improvement in the perceptual (P = 0.008), acoustic (P = 0.040), aerodynamic (P = 0.009 and <0.001), and self-evaluation parameters (P = 0.011). Our findings provide evidence that group voice therapy can be associated with improvements in perceptual, acoustic, aerodynamic, and self-evaluated parameters in some patients with dysphonia. Controlled, randomized studies are needed in follow-up. This method of treatment may be a means of reducing the costs and waiting lists associated with rehabilitative treatment, and enhancing patients' motivation and compliance.

Early Voice Therapy in Patients with Unilateral Vocal Fold Paralysis

Objective: The purpose of this work was to study the efficacy of early voice therapy in the management of patients with unilateral vocal fold paralysis. Patients and Methods: Three groups of patients suffering from unilateral vocal fold paralysis were subjected to a protocol of voice evaluation including auditory-perceptual voice analysis, the Dysphonia Severity Index (DSI) and the 20-item Voice Problem Self-Assessment Scale (VPSS-20). Patients were also examined using video laryngostroboscopy. The early voice therapy group was enrolled in a voice therapy program for 16 sessions as soon as the patients were diagnosed; the second group of patients did not receive voice therapy during the course of their ailment. The late voice therapy group was enrolled in a voice therapy after a period of at least 6 months following the onset of vocal fold paralysis. All studied patients were reevaluated after a period of 2 months. Results: The early voice therapy group showed better outcomes regarding VPSS-20 scores, auditory-perceptual voice analysis as well as the DSI. Conclusion: Early onset of voice therapy may enhance the reduction in glottal gap and improvement of voice quality by hindering the development of faulty hyperfunctional compensatory behaviors; early voice therapy may therefore enhance the patient's quality of life.

Therapeutic Decision Making of the Unilateral Vocal Cord Palsy after Thyroidectomy Using Thyroidectomy‐Related Voice Questionnaire

Objectives: Investigate the efficacy of early management of post-thyroidectomy unilateral vocal cord palsy (UVCP) and the clinical utility of the thyroidectomy-related voice questionnaire (TVQ) when planning UVCP treatment. Methods: The study group comprised 48 consecutive patients diagnosed with UVCP after thyroidectomy. Laryngoscopic examination and voice analysis were conducted, and the TVQ was administered pre-thyroidectomy and at 2 weeks and 1, 3, 6, and 12 months post-thyroidectomy. Twenty-five patients with aspiration symptoms and severe vocal difficulties received injection laryngoplasty, and 23 with no aspiration symptoms and relatively mild vocal difficulties underwent voice therapy. We performed a video fluoroscopic swallowing study on each patient 2 weeks after thyroidectomy and 1 month following the procedure. Results: The average total TVQ scores 2 weeks afterthyroidectomy were 51.92 ± 11.42 in the injection laryngoplasty group and 35.78 ± 12.99 in the voice therapy group. Both subjective and objective parameters improved significantly at 1 month after treatment and continued to improve slowly over the next 12 months ( P &lt; .01) in both groups. TVQ scores were significantly lower in the injection laryngoplasty group than in the voice therapy group 1 month post-intervention ( P &lt; .01). At the study end point, the greatest improvement in subjective symptoms occurred in temporary VCP patients who underwent injection laryngoplasty. The optimal TVQ score cutoff distinguishing the 2 groups was 45 (68.0% sensitivity, 78.3% specificity). Conclusions: Early management following timely diagnosis of post-thyroidectomy UVCP can improve symptoms within 1 month. Moreover, application of TVQ will aid clinicians to plan treatment for postoperative VCP patients.

TVQ scores were significantly lower in the injection laryngoplasty group than in the voice therapy group 1 month post-intervention (p < 0.01). At the study end point, the greatest improvement in subjective symptoms occurred in temporary VCP patients who underwent injection laryngoplasty. The optimal TVQ score cut-off distinguishing the two groups was 45 (68.0 % sensitivity, 78.3 % specificity). In conclusion, early management following timely diagnosis of post-thyroidectomy UVCP can improve symptoms within 1 month. Moreover, application of TVQ will aid clinicians to plan treatment for postoperative VCP patients.

Feasibility of group voice therapy for individuals with Parkinson's disease

Purpose The primary purpose was to demonstrate the feasibility of executing treatment tasks focused on increasing loudness in a group format for individuals with Parkinson's disease (PD). A second purpose was to report preliminary pre-to-post treatment outcomes for individuals with PD immediately after they complete the group program. Methods The group intervention is described. Fifteen adults with PD who participated in the group and three clinicians leading the group provided feedback about the execution of the intervention. The participants also provided voice samples and self-ratings of voice handicap once before completing the 8-week voice group and once immediately after completing the voice group. Outcome measures included voice intensity, fundamental frequency (F0) mean, standard deviation and range, maximum phonation time, and listener judgment of loudness. Results Feedback from the clinicians suggested that many, but not all, of the voice activities could be executed within a group setting. Participants with PD indicated they understood the focus of the group and that subjectively they felt the group was helpful for increasing loudness. Statistically significant increases occurred for voice intensity, F0 maximum, and F0 range. Voice handicap scores decreased significantly and 80% of the participants were judged louder post intervention. Conclusions Clinician and participant feedback indicated that it was feasible to execute most LSVT ® tasks in a group format with some modifications. The preliminary outcome data indicate that the targeted behavior (voice dB and loudness) did change in the predicted direction as did several other measures. Future studies comparing outcomes of group intervention to the gold standard LSVT ®, and exploring retention of treatment gains over time, are needed. Learning outcomes: After reading the manuscript, readers will be able to: (1) Describe previous attempts at group intervention to improve voice for individuals with Parkinson's disease. (2) List three ways that the group intervention tried in this study differed from LSVT ®. (3) Identify three limitations to this study that must be addressed before advocating implementation of the group approach in clinical situations.

The Effectiveness of Group Voice Therapy: A Group Climate Perspective

Group therapy has frequently been adopted as a service delivery model for providing voice therapy. However, currently no literature has focused on understanding the underlying processes that are unique to group therapy, which contribute to treatment success. This study aimed at investigating the role of group climate in voice group therapy. Prospective case series. Twelve teachers with hyperfunctional dysphonia attended eight sessions of group voice therapy. Treatment comprised both direct and indirect voice therapy. Therapy techniques were introduced and practiced in a large group and small group format. Outcome measures were taken using perceptual evaluation, videostroboscopy measures, voice-related quality-of-life (V-RQOL) measures, and vocal symptom scores. The Group Climate Questionnaire was used to measure the underlying process of group therapy. Treatment outcome was measured immediately posttreatment and at 6-months posttreatment. Results indicated statistically significant improvement in the participants' V-RQOL measures and the vocal symptom scores. Treatment gain was noted to sustain up to 6-months posttreatment. The Group Climate Questionnaire indicated that the treatment group is considered as "engaging" rather than "conflicting," which is considered to be associatedwith positive treatment outcome. Group therapy as a service delivery model possesses many advantages from the psychosocial, clinical, health resources allocation perspective. This study demonstrated that group climate plays a significant role in determining treatment success in group voice therapy.
