ABSTRACT

BACKGROUND: Pulmonary rehabilitation (PR) following severe and very severe COVID-19 infection is known to be effective, according to typical assessments. However, not all patients benefit from PR to the same extent. This analysis aimed to identify the impact of different factors on PR outcomes in post-COVID-19 patients. METHODS: This prospective observational study included 184 post-COVID-19 patients. The achievement of the predicted reference walking distance (6 min walking distance (6-MWD)) served as a parameter with which to identify responders and non-responders to PR. Several parameters (e.g., Functional Independent Measurement (FIM); pulmonary function testing (Forced Vital Capacity, FVC); 6MWD) were assessed in order to estimate their impact on PR success. Logistic regression models and classification and regression trees were used for multivariate analysis. RESULTS: A total of 94 patients (51%) reached their reference 6MWD by the end of PR. FVC (0.95 (0.93-0.97)), 6MWD at admission (0.99 (0.99-1.00)), and FIM motoric (0.96 (0.93-0.99)) correlated with the risk not reaching the reference distance. The most important variable was the 6MWD at admission. Classification and regression tree identified 6MWD ≥ 130 m at admission and FVC predicted of >83% as the strongest predictor for reaching predicted 6-MWD. CONCLUSION: Post-COVID-19 patients with lower 6MWD, lower motoric FIM scores and lower FVC at admission have a high risk of not reaching their target values of physical performance despite intensive rehabilitation. As well as identifying them, it is of utmost importance to develop optimal PR concepts for these patients.

ABSTRACT

OBJECTIVE: The COVID-19 pandemic affects a large number of patients. The impact on feasibility and outcome of rehabilitation during COVID-19 actually remains unclear. Nosocomial infection of healthcare workers or hospitalized patients is common, and prevention of nosocomial infections during rehabilitation is challenging. Therefore, we analyzed a cohort of nosocomial infected COVID-19 patients in a single-center inpatient rehabilitation clinic and described performance and outcome. DESIGN: The cohort (N = 27) describes patients with nosocomial SARS-CoV-2 infection while participating in neuromusculoskeletal rehabilitation. Infection was caused by an initially unidentified so-called superspreader. We compared this cohort with all neuromusculoskeletal rehabilitation inpatients of 2019 (comparison group). Normally distributed continuous variables were presented as mean with standard deviation and the t test was used for comparison between groups. Linear regression was used to assess the impact of COVID-19 on Functional Independence Measure at discharge. RESULTS: COVID-19 patients were mostly male (66.7%) with an age of 71.5 ± 12.3 yrs. Age, sex, and cumulated comorbidities of the comparison group (n = 786) were not different from the COVID-19 group. A total of 92.6% of COVID-19 patients had a mild or moderate course, two patients had to be referred to acute hospital because of respiratory failure, and one of these patients died in the acute hospital. After implementation of a strict hygiene concept, no further nosocomial COVID-19 infections were detected. The rehabilitation duration was significantly longer in the COVID-19 group (54.2 ± 23.6 days vs. 32.1 ± 17.7 days, P < 0.001). Daily therapy duration was 132.3 ± 44 mins before SARS-CoV-2 infection and reduced to 81.9 ± 27.3 mins during COVID-19 (P < 0.001). After discontinuation of isolation measures, therapy duration increased significantly (99.3 ± 70.2 mins, P < 0.05).The baseline Functional Independence Measure score was higher in the COVID-19 group (91.93 ± 25.64 points vs. 82.98 ± 22.73 points) and Functional Independence Measure improvements were lower in COVID-19 patients than in the 2019 comparison group (6.96 ± 8.96 points vs. 20.3 ± 15.98 points, P < 0.001). COVID-19 infection itself had a strong negative impact on Functional Independence Measure change as identified by regression analysis. Linear regression analysis showed that COVID-19 reduced the Functional Independence Measure at discharge by 8.9 points (95% CI = -14.725 to -3.097, P = 0.003) after correction for Functional Independence Measure at admission, age, sex, and morbidity index at admission. CONCLUSIONS: COVID-19 had a strong negative impact on rehabilitation benefits as assessed by Functional Independence Measure. Neuromusculoskeletal rehabilitation could be continued, but all patients received less therapy minutes during isolation. After implementation of a strict COVID-19-specific hygiene concept, no further infections were detected.

ABSTRACT

BACKGROUND: Results of medialization thyroplasty for treatment of unilateral vocal fold paralysis are often unsatisfactory. This study compares glottal closure and voice quality after use of 2 different medialization implant types: VoCoM and TVFMI. METHODS: In all, 26 patients with unilateral vocal fold paralysis following thoracic surgery underwent medialization thyroplasty. In 11 patients (group I), a hydroxyapatite implant (VoCoM) was used. In 15 patients (group II), a titanium implant (TVFMI) was used. Preoperative and postoperative glottal closure and voice function were assessed with videostroboscopy, perceptual and objective voice measures, and the Voice Dysfunction Index (VDI). RESULTS: Group II showed a higher rate of complete glottal closure and greater improvement in perceived hoarseness, maximal phonation time, and maximal voice intensity than those in group I. CONCLUSIONS: With the individually adjustable titanium implant, better glottal closure and better functional outcome (phonation time and voice quality) were achieved.

ABSTRACT

Several studies revealed a high percentage of voice problems in future teachers. The influence of vocal constitution on the vocal endurance is, however, still unclear. The goal of this study was to evaluate whether the increase of voice fundamental frequency (F0) during teaching is caused by (1) autonomic regulation patterns under stress, (2) anxiety as an emotional factor, or (3) limitations in voice constitution. Thirty-three subjects with either normal voice constitution (n = 15, group 1) or constitutional hypofunction (n = 18, group 2) assessed by voice range profile measurements were enrolled in this study. Furthermore, they underwent a standardized baseline test to register selected autonomic test parameters and were classified into autonomic outlet types (AOT) as proposed by Johannes et al. Later the subjects were examined during 1 hour of teaching (field study). The parameters tested included heart rate, pulse transition time, finger temperature, and voice fundamental frequency. To measure situational anxiety and general anxiety proneness, a state-trait anxiety inventory was taken. Eleven subjects per group were identified as autonomic stable (AOT 1), two per group as responding cardiovascularly (AOT 2), and two of group 1 and four of group 2, respectively, as having higher heart rate and higher blood pressure responses to stress (AOT 4). One subject had to be excluded because of missing data. However, statistical analyses showed no differences between AOT groups regarding the voice constitution groups. Increased fundamental frequencies of speaking voice after 30 and 45 minutes of teaching were found in group 2 (constitutional hypofunction). No effect of state or trait anxiety on voice endurance could be detected. Thus, the increase of fundamental frequency of voice has to be regarded as a consequence of vocal fatigue. A constitutionally weak voice seems to be a risk factor for developing a professional voice disorder.
