Quality of Life in Dysphonic Patients

Voice disorders can affect social life. Dysphonic patients report symptoms of psychological distress as a direct consequence of their dysphonia. It is assumed that their health-related quality of life (HRQL) is reduced. The purpose of this study was to find out whether changes of HRQL depend on the kind of voice disorder (organic or functional) and on the sex of the person affected. A total of 108 adult patients took part in the study, and patients with malignancies were excluded. Test persons were asked to complete the SF-36 questionnaire on their health-related quality of life without prior information about their individual diagnosis. The results of this study show that voice disorders significantly influence patients' HRQL. There are no statistically significant differences between patients suffering from organic and functional voice disorders or between dysphonic women and men. When comparing the results obtained in this study with those in the literature, surprisingly, it seems that the manner in which a person experiences a voice disorder depends on the individual cultural background. Patients with functional voice disorders have similar reduction in HRQL as those with organic voice disorders. HRQL in dysphonic women does not differ from the one in dysphonic men. The results allow for the conclusion that changes of HRQL do not depend on the kind of voice disorder and not on the sex of the person affected.     

Evidence of Improvement in Various Impairments by Exercise Interventions in Patients with Knee Osteoarthritis: A Systematic Review and Meta-analysis of Randomized Clinical Trials

Purpose: To investigate improvement in various impairments by exercise interventions in patients with knee osteoarthritis (OA). Methods: We collected data on randomized controlled trials (RCTs) comparing the effects of exercise intervention with those of either nonintervention or psychoeducational intervention in patients with knee OA. Data on pain, stiffness, muscle strength, range of motion, flexibility, maximal oxygen uptake, and position sense were synthesized. The Grading of Recommendations Assessment, Development, and Evaluation system was used to determine the quality of the evidence. Results: Thirty-three RCTs involving 3,192 participants were identified. Meta-analysis provided highquality evidence that exercise intervention improves maximal oxygen uptake, and moderate-quality evidence that exercise intervention also improves pain, stiffness, knee extensor and flexor muscle strength, and position sense. The evidence that exercise intervention improves knee extension and flexion range of motion was deemed as undetermined-quality. Conclusion: In patients with knee OA, improvement in pain, stiffness, muscle strength, maximal oxygen uptake, and position sense with the use of exercise intervention can be expected. Although the quality of evidence of the effect of exercise intervention on range of motion was inconclusive, exercise intervention should be recommended for patients with knee OA to improve various impairments.     

Voice Therapy Improves Quality of Life in Age-Related Dysphonia: A Case-Control Study

The objective of the study is to determine the efficacy of voice therapy in the treatment of age-related dysphonia. The study was conducted using a retrospective case-control chart review. The medical records of 54 patients older than 60 years diagnosed with age-related dysphonia without complicating diagnoses were reviewed. Patients who chose to undergo voice therapy were grouped as cases. Patients who chose not to undergo voice therapy were grouped as controls. The voice-related quality of life (VRQOL) measure was used to measure outcomes before and after treatment in cases and at a minimum 2-month follow-up in controls. Of the 54 patients, 19 (10 female, 9 male; mean age 73 years) chose to undergo voice therapy and filled in >1 VRQOL questionnaire. Six patients (3 female, 3 male; mean age 66 years) chose not to undergo voice therapy and filled in >1 VRQOL questionnaire. The 19 cases experienced a mean improvement in VRQOL score of 19.21 (2-tailed matched pairs t test P=0.00038) after a mean of 4.1 voice therapy sessions and 5.1 months. The six controls experienced a mean change in VRQOL score of 0.42 (2-tailed matched pairs t test P=0.96) after a mean of 3.3 months. Voice therapy leads to statistically significant improvement in the VRQOL life in elderly patients with age-related dysphonia. It is an efficacious noninvasive therapy for this disease.     

Effectiveness of Physical Therapy in Patients with Tension-type Headache: Literature Review

Background: Tension-type headache (TTH) is a disease with a great incidence on quality of life and with a significant socioeconomic impact. Objectives: The aim of this review is to determine the effectiveness of physical therapy by using manual therapy (MT) for the relief of TTH. Data sources: A review was done identifying randomized controlled trials through searches in MEDLINE, PEDro, Cochrane and CINAHL (January 2002 – April 2012). Study selection: English-language studies, with adult patients and number of subjects not under 11, diagnosed with episodic tension-type headache (ETTH) and chronic tension-type headache (CTTH) were included. Data extraction: Initial search was undertaken with the words Effectiveness, Tension-type headache, and Manual therapy (39 studies). In addition, a search which included terms related to treatments such as physiotherapy, physical therapy, spinal manipulation was performed (25 studies). Results: From the two searches 9 studies met the inclusion criteria and were analysed finding statistically significant results: 1) myofascial release, cervical traction, neck muscles trigger points in cervical thoracic muscles and stretching; 2) Superficial heat and massage, connective tissue manipulation and vertebral Cyriax mobilization; 3) cervical or thoracic spinal manipulation and cervical chin-occipital manual traction; 4) massage, progressive relaxation and gentle stretching, program of active exercises of shoulder, neck and pericranial muscles; 5) massage, passive rhythmic mobilization techniques, cervical, thoracic and lumbopelvic postural correction and cranio-cervical exercises; 6) progressive muscular relaxation combined with joint mobilization, functional, muscle energy, and strain/counterstrain techniques, and cranial osteopathic treatment; 7) massage focused on relieving myofascial trigger point activity; 8) pressure release and muscle energy in suboccipital muscles; 9) combination of mobilizations of the cervical and thoracic spine, exercises and postural correction. All studies used a combination of different techniques and none analyzed treatments separately, also all the studies have assessed aspects related to TTH beyond frequency and intensity of pain. Conclusions: The findings from these studies showed evidence that physiotherapy with articulatory MT, combined with cervical muscle stretching and massage are effective for this disease in different aspects related with TTH. No evidence was found of the effectiveness of the techniques applied separately.     

Voice-related Quality of Life in Laryngectomees: Assessment Using the VHI and V-RQOL Symptom Scales

The primary purpose of this study was to investigate the effect of the voice impairment across the physical, emotional, and functional domains in patients using valved speech following total laryngectomy with the help of two symptom specific scales. The study design used was a cross-sectional cohort. The setting was the Head and Neck Oncology Unit of a tertiary referral centre. Subjects were 54 patients who had undergone total laryngectomy. Two voice-specific questionnaires, the Voice-Related Quality of Life (V-RQOL-short form) Measure, and the Voice Handicap Index (VHI-long form) were used. The main outcome measure was patient perception of the voice following total laryngectomy in response to specific questions correlated with sociodemographic/treatment factors. Responses were received from 40 males and 14 females (response rate of 85.7%) with a median age of 63.4 years (range: 37-84). The V-RQOL overall analysis showed that 3 patients (5.6%) scored "excellent," 29 patients (53.7%) "fair to good," 14 patients (25.9%) "poor to fair," and 8 patients (14.8%) "poor." Analysis of the VHI revealed that 20 patients (37.0%) had a minimal handicap, 20 patients (37.0%) a moderate handicap, and 14 patients (25.9%) had a serious voice handicap. The individual domain or subscale scores for the VHI revealed a mean (SD) functional score of 15.8 (7.7), a physical score of 13.6 (7.2), and finally an emotional score of 11.6 (8.9). Functional aspects of the voice were significantly affected by age, radiotherapy, and chemotherapy (Spearman rho, P=0.01; Mann-Whitney, P=0.04 and P=0.01). The physical aspects of the voice were significantly affected by age and chemotherapy (Spearman rho, P=0.004; Mann-Whitney, P=0.04). Only age significantly affected the emotional aspects of the voice (Spearman rho, P=0.002). We found a strong correlation (Spearman rho, P<0.001) between the V-RQOL and VHI questionnaires. Our study revealed that the V-RQOL and VHI scores in our series of patients following voice restoration in laryngectomees were consistent with that reported in the literature. Only age, radiation, and chemotherapy were seen to influence the voice handicap scores. In addition, both symptom scales had good correlation between them and either one could be used with reliability in laryngectomees with a few modifications.
