This is the first study that aimed to establish the MCID of the Clinical chronic obstructive pulmonary disease (COPD) Questionnaire (CCQ), the COPD Assessment Test (CAT) and the St George's Respiratory Questionnaire (SGRQ) in the same pulmonary rehabilitation population using multiple approaches. In total, 451 COPD patients participated in a 3-week Pulmonary Rehabilitation (PR) programme (58 years, 65\% male, 43 pack-years, GOLD stage II/III/IV 50/39/11\%). Techniques used to assess the MCID were anchor-based approaches, including patient-referencing, criterion-referencing and questionnaire-referencing, and the distribution-based methods standard error of measurement (SEM), 1.96SEM and half standard deviation (0.5s.d.). Patient- and criterion-referencing led to MCID estimates of 0.56 and 0.62 (CCQ); 3.12 and 2.96 (CAT); and 8.40 and 9.28 (SGRQ). Questionnaire-referencing suggested MCID ranges of 0.28-0.61 (CCQ), 1.46-3.08 (CAT) and 6.86-9.47 (SGRQ). The SEM, 1.96SEM and 0.5s.d. were 0.29, 0.56 and 0.46 (CCQ); 3.28, 6.43 and 2.80 (CAT); 5.20, 10.19 and 6.06 (SGRQ). Pooled estimates were 0.52 (CCQ), 3.29 (CAT) and 7.91 (SGRQ) for improvement. MCID estimates differed depending on the method used. Pooled estimates suggest clinically relevant improvements needing to exceed 0.40 on the CCQ, 3.00 on the CAT and 7.00 on the SGRQ for moderate to very severe COPD patients. The MCIDs of the CAT and SGRQ in the literature might be too low, leading to overestimation of treatment effects for patients with COPD.}, language = {en} } @article{FlacheneckerBuresGawliketal.2020, author = {Flachenecker, Peter and Bures, Anna Karoline and Gawlik, Angeli and Weiland, Ann-Christin and Kuld, Sarah and Gusowski, Klaus and Streber, Ren{\´e} and Pfeifer, Klaus and Tallner, Alexander}, title = {Efficacy of an internet-based program to promote physical activity and exercise after inpatient rehabilitation in persons with multiple sclerosis: a randomized, single-blind, controlled study}, series = {International Journal of Environmental Research and Public Health}, volume = {17}, journal = {International Journal of Environmental Research and Public Health}, number = {12}, issn = {1660-4601}, doi = {10.3390/ijerph17124544}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-207863}, year = {2020}, abstract = {Background: Multimodal rehabilitation improves fatigue and mobility in persons with multiple sclerosis (PwMS). Effects are transient and may be conserved by internet-based physical activity promotion programs. Objective: Evaluate the effects of internet-based physical activity and exercise promotion on fatigue, quality of life, and gait in PwMS after inpatient rehabilitation. Methods: PwMS (Expanded Disability Status Scale (EDSS) ≤ 6.0, fatigue: W{\"u}rzburg Fatigue Inventory for Multiple Sclerosis (WEIMuS) ≥ 32) were randomized into an intervention group (IG) or a control group (CG). After rehabilitation, IG received 3 months of internet-based physical activity promotion, while CG received no intervention. Primary outcome: self-reported fatigue (WEIMuS). Secondary outcomes: quality of life (Multiple Sclerosis Impact Scale 29, MSIS-29), gait (2min/10m walking test, Tinetti score). Measurements: beginning (T0) and end (T1) of inpatient rehabilitation, 3 (T2) and 6 (T3) months afterwards. Results: 64 of 84 PwMS were analyzed (IG: 34, CG: 30). After rehabilitation, fatigue decreased in both groups. At T2 and T3, fatigue increased again in CG but was improved in IG (p < 0.001). MSIS-29 improved in both groups at T1 but remained improved at T2 and T3 only in IG. Gait improvements were more pronounced in IG at T2. Conclusions: The study provides Class II evidence that the effects of rehabilitation on fatigue, quality of life, and gait can be maintained for 3-6 months with an internet-based physical activity and exercise promotion program.}, language = {en} } @article{Halbig Babu Gatter etal.2022, author = {Halbig , Andreas and Babu , Sooraj K. and Gatter , Shirin and Latoschik , Marc Erich and Brukamp, Kirsten and von Mammen , Sebastian}, title = {Opportunities and challenges of Virtual Reality in healthcare - a domain experts inquiry}, series = {Frontiers in Virtual Reality}, volume = {3}, journal = {Frontiers in Virtual Reality}, issn = {2673-4192}, doi = {10.3389/frvir.2022.837616}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-284752}, year = {2022}, abstract = {In recent years, the applications and accessibility of Virtual Reality (VR) for the healthcare sector have continued to grow. However, so far, most VR applications are only relevant in research settings. Information about what healthcare professionals would need to independently integrate VR applications into their daily working routines is missing. The actual needs and concerns of the people who work in the healthcare sector are often disregarded in the development of VR applications, even though they are the ones who are supposed to use them in practice. By means of this study, we systematically involve health professionals in the development process of VR applications. In particular, we conducted an online survey with 102 healthcare professionals based on a video prototype which demonstrates a software platform that allows them to create and utilise VR experiences on their own. For this study, we adapted and extended the Technology Acceptance Model (TAM). The survey focused on the perceived usefulness and the ease of use of such a platform, as well as the attitude and ethical concerns the users might have. The results show a generally positive attitude toward such a software platform. The users can imagine various use cases in different health domains. However, the perceived usefulness is tied to the actual ease of use of the platform and sufficient support for learning and working with the platform. In the discussion, we explain how these results can be generalized to facilitate the integration of VR in healthcare practice.}, language = {en} } @article{KaemmererKlementJoosetal.2021, author = {K{\"a}mmerer, Ulrike and Klement, Rainer J. and Joos, Fabian T. and S{\"u}tterlin, Marc and Reuss-Borst, Monika}, title = {Low carb and ketogenic diets increase quality of life, physical performance, body composition, and metabolic health of women with breast cancer}, series = {Nutrients}, volume = {13}, journal = {Nutrients}, number = {3}, issn = {2072-6643}, doi = {10.3390/nu13031029}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-234209}, year = {2021}, abstract = {Breast cancer (BC) patients often ask for a healthy diet. Here, we investigated a healthy standard diet (SD), a low carb diet (LCD), and a ketogenic diet (KD) for BC patients during the rehabilitation phase. KOLIBRI was an open-label non-randomized one-site nutritional intervention trial, combining inpatient and outpatient phases for 20 weeks. Female BC patients (n = 152; mean age 51.7 years) could select their diet. Data collected were: Quality of life (QoL), spiroergometry, body composition, and blood parameters. In total 30, 92, and 30 patients started the KD, LCD, and SD, respectively. Of those, 20, 76, and 25 completed the final examination. Patients rated all diets as feasible in daily life. All groups enhanced QoL, body composition, and physical performance. LCD participants showed the most impressive improvement in QoL aspects. KD participants finished with a very good physical performance and muscle/fat ratio. Despite increased cholesterol levels, KD patients had the best triglyceride/high-density lipoprotein (HDL) ratio and homeostatic model assessment of insulin resistance index (HOMA-IR). Most metabolic parameters significantly improved in the LCD group. SD participants ended with remarkably low cholesterol levels but did not improve triglyceride/HDL or HOMA-IR. In conclusion, both well-defined KDs and LCDs are safe and beneficial for BC patients and can be recommended during the rehabilitation phase.}, language = {en} } @article{MusekampGerlichEhlebrachtKoenigetal.2016, author = {Musekamp, Gunda and Gerlich, Christian and Ehlebracht-K{\"o}nig, Inge and Faller, Hermann and Reusch, Andrea}, title = {Evaluation of a self-management patient education program for patients with fibromyalgia syndrome: study protocol of a cluster randomized controlled trial}, series = {BMC Musculoskeletal Disorders}, volume = {17}, journal = {BMC Musculoskeletal Disorders}, number = {55}, doi = {10.1186/s12891-016-0903-4}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-146075}, year = {2016}, abstract = {Background Fibromyalgia syndrome (FMS) is a complex chronic condition that makes high demands on patients' self-management skills. Thus, patient education is considered an important component of multimodal therapy, although evidence regarding its effectiveness is scarce. The main objective of this study is to assess the effectiveness of an advanced self-management patient education program for patients with FMS as compared to usual care in the context of inpatient rehabilitation. Methods/Design We conducted a multicenter cluster randomized controlled trial in 3 rehabilitation clinics. Clusters are groups of patients with FMS consecutively recruited within one week after admission. Patients of the intervention group receive the advanced multidisciplinary self-management patient education program (considering new knowledge on FMS, with a focus on transfer into everyday life), whereas patients in the control group receive standard patient education programs including information on FMS and coping with pain. A total of 566 patients are assessed at admission, at discharge and after 6 and 12 months, using patient reported questionnaires. Primary outcomes are patients' disease- and treatment-specific knowledge at discharge and self-management skills after 6 months. Secondary outcomes include satisfaction, attitudes and coping competences, health-promoting behavior, psychological distress, health impairment and participation. Treatment effects between groups are evaluated using multilevel regression analysis adjusting for baseline values. Discussion The study evaluates the effectiveness of a self-management patient education program for patients with FMS in the context of inpatient rehabilitation in a cluster randomized trial. Study results will show whether self-management patient education is beneficial for this group of patients.}, language = {en} } @article{ReppenhagenBeckerKugleretal.2023, author = {Reppenhagen, Stephan and Becker, Roland and Kugler, Andreas and John, Dominik and Kopf, Sebastian and Anetzberger, Hermann}, title = {Hand dominance is not of significance in performing fundamental arthroscopic skills simulation training tasks}, series = {Arthroscopy, Sports Medicine, and Rehabilitation}, volume = {5}, journal = {Arthroscopy, Sports Medicine, and Rehabilitation}, number = {5}, issn = {2666-061X}, doi = {10.1016/j.asmr.2023.100767}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-350432}, year = {2023}, abstract = {Purpose To compare the performance of the dominant and nondominant hand during fundamental arthroscopic simulator training. Methods Surgical trainees who participated in a 2-day simulator training course between 2021 and 2023 were classified, according to their arthroscopic experience in beginners and competents. Only right-handed individuals with complete data sets were included in the study. Ambidexterity was trained using a box trainer (Fundamentals of Arthroscopic Surgery Training, Virtamed AG, Schlieren, Switzerland).Two tasks, periscoping for learning camera guidance and triangulation for additional instrument handling, were performed 4 times with the camera in the dominant hand and then in the nondominant hand. For each task, exercise time, camera path length, and instrument path length were recorded and analyzed. Results Out of 94 participants 74 right-handed individuals (22 females, 52 males) were classified to novices (n = 43, less than 10 independently performed arthroscopies) and competents (n = 31, more than 10 independently performed arthroscopies). Competents performed significantly better than novices. No significant difference was found after changing the guiding hand for the camera from the dominant to the nondominant hand regarding the camera path length and the instrument path length. Notably, tasks were performed even faster when using the camera in the nondominant hand. Conclusions Our data demonstrate that the learned manual skills during basic arthroscopic training are quickly transferred to the contralateral side. In consequence, additional fundamental skills training for camera guidance and instrument handling of the nondominant hand are not necessary. Clinical Relevance For skillful arthroscopy, camera guidance and instrument handing must be equally mastered with both hands. It is important to understand how hand dominance may affect learning during arthroscopic simulator training.}, language = {en} } @article{WiedmannHeuschmannHillmannetal.2014, author = {Wiedmann, Silke and Heuschmann, Peter U. and Hillmann, Steffi and Busse, Otto and Wiethoelter, Horst and Walter, Georg M. and Seidel, Guenter and Misselwitz, Bjoern and Janssen, Alfred and Berger, Klaus and Burmeister, Christoph and Matthias, Christine and Kolominsky-Rabas, Peter and Hermanek, Peter}, title = {The Quality of Acute Stroke Care-an Analysis of Evidence-Based Indicators in 260 000 Patients}, series = {Deutsches {\"A}rzteblatt International}, volume = {111}, journal = {Deutsches {\"A}rzteblatt International}, number = {45}, issn = {1866-0452}, doi = {10.3238/arztebl.2014.0759}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-114747}, pages = {759-765}, year = {2014}, abstract = {Background: Stroke patients should be cared for in accordance with evidence-based guidelines. The extent of implementation of guidelines for the acute care of stroke patients in Germany has been unclear to date. Methods: The regional quality assurance projects that cooperate in the framework of the German Stroke Registers Study Group (Arbeitsgemeinschaft Deutscher Schlaganfall-Register, ADSR) collected data on the care of stroke patients in 627 hospitals in 2012. The quality of the acute hospital care of patients with stroke or transient ischemic attack (TIA) was assessed on the basis of 15 standardized, evidence-based quality indicators and compared across the nine participating regional quality assurance projects. Results: Data were obtained on more than 260 000 patients nationwide. Intravenous thrombolysis was performed in 59.7\% of eligible ischemic stroke patients patients (range among participating projects, 49.7-63.6\%). Dysphagia screening was documented in 86.2\% (range, 74.8-93.1\%). For the following indicators, the defined targets were not reached for all of Germany: antiaggregation within 48 hours, 93.4\% (range, 86.6-96.4\%); anticoagulation for atrial fibrillation, 77.6\% (range, 72.4-80.1\%); standardized dysphagia screening, 86.2\% (range, 74.8-93.1\%); oral and written information of the patients or their relatives, 86.1\% (range, 75.4-91.5\%). The rate of patients examined or treated by a speech therapist was in the target range. Conclusion: The defined targets were reached for most of the quality indicators. Some indicators, however, varied widely across regional quality assurance projects. This implies that the standardization of care for stroke patients in Germany has not yet been fully achieved.}, language = {en} } @article{WinterKernGalletal.2021, author = {Winter, Carla and Kern, Florian and Gall, Dominik and Latoschik, Marc Erich and Pauli, Paul and K{\"a}thner, Ivo}, title = {Immersive virtual reality during gait rehabilitation increases walking speed and motivation: a usability evaluation with healthy participants and individuals with multiple sclerosis and stroke}, series = {Journal of Neuroengineering and Rehabilitation}, volume = {18}, journal = {Journal of Neuroengineering and Rehabilitation}, number = {1}, issn = {1743-0003}, doi = {10.1186/s12984-021-00848-w}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-258698}, year = {2021}, abstract = {Background: The rehabilitation of gait disorders in patients with multiple sclerosis (MS) and stroke is often based on conventional treadmill training. Virtual reality (VR)-based treadmill training can increase motivation and improve therapy outcomes. The present study evaluated an immersive virtual reality application (using a head-mounted display, HMD) for gait rehabilitation with patients to (1) demonstrate its feasibility and acceptance and to (2) compare its short-term effects to a semi-immersive presentation (using a monitor) and a conventional treadmill training without VR to assess the usability of both systems and estimate the effects on walking speed and motivation. Methods: In a within-subjects study design, 36 healthy participants and 14 persons with MS or stroke participated in each of the three experimental conditions (VR via HMD, VR via monitor, treadmill training without VR). Results: For both groups, the walking speed in the HMD condition was higher than in treadmill training without VR and in the monitor condition. Healthy participants reported a higher motivation after the HMD condition as compared with the other conditions. Importantly, no side effects in the sense of simulator sickness occurred and usability ratings were high. No increases in heart rate were observed following the VR conditions. Presence ratings were higher for the HMD condition compared with the monitor condition for both user groups. Most of the healthy study participants (89\%) and patients (71\%) preferred the HMD-based training among the three conditions and most patients could imagine using it more frequently. Conclusions For the first time, the present study evaluated the usability of an immersive VR system for gait rehabilitation in a direct comparison with a semi-immersive system and a conventional training without VR with healthy participants and patients. The study demonstrated the feasibility of combining a treadmill training with immersive VR. Due to its high usability and low side effects, it might be particularly suited for patients to improve training motivation and training outcome e. g. the walking speed compared with treadmill training using no or only semi-immersive VR. Immersive VR systems still require specific technical setup procedures. This should be taken into account for specific clinical use-cases during a cost-benefit assessment.}, language = {en} }
