Activities of Daily Living Are Improved by Inpatient Multimodal Complex Treatment for PD-a Real-World Cohort Study.

Background: The multimodal complex treatment for Parkinson's disease (MCT) provides inpatient care by a multi-disciplinary team for people with Parkinson's disease (PwP) in Germany. Objectives: We conducted a 5-year real-world mono-center cohort study to describe the effectiveness of MCT in the full cohort and various subgroups and outcome predictors. Methods: We collected an anonymized dataset between Jan 2015 and Dec 2019, involving N = 1773. The self-reported MDS-UPDRS part II was used as primary outcome, and clinical routine data for explanatory variables. PwP were categorized as responders or non-responders according to a response of at least 3 points 4 weeks after discharge. Results: N = 591 complete data records were available for statistical analyses. The full group improved by -2.4 points on the MDS-UPDRS II (P = <0.0001). 47.7% (n = 282) and 52.3% (n = 309) were coded as responders and non-responders, respectively. A clinically meaningful response was positively associated to age (χ2 = 11.07, P = 0.018), as well as baseline-severity of the MDS-UPDRS II (χ2 = 6.05, P = 0.048) and negatively associated to the presence of psychiatric disorder (χ2 = 3.9, P = 0.048) and cognitive dysfunction (χ2 = 7.29, P = 0.007). Logistic regression showed that baseline severity of the MDS-UPDRS II predicted therapy success. PwP with moderate baseline-severity had an about 2fold chance (OR 2.08; 95% CI 1.20-3.61; P = 0.009) and with severe an about 6fold chance (OR 5.92; 95% CI 2.76-12.68; P < 0.0001) to benefit clinically meaningful. Discussion: In a naturalistic setting of a specialized Parkinson's center, MCT improved ADL disability of PwP at least 4 weeks after discharge. Moderately and severely impaired patients were more likely to achieve clinically meaningful responses.

Virtual Reality for Neurorehabilitation: Insights From 3 European Clinics.

Virtual reality for the treatment of motor impairment is a burgeoning application of digital technology in neurorehabilitation. Virtual reality systems pose an opportunity for health care providers to augment the dose of task-oriented exercises delivered both in the clinic, and via telerehabilitation models in the home. The technology is almost exclusively applied as an adjunct to traditional approaches and is typically characterized by the use of gamified exergames which feature task-oriented physiotherapy exercises. At present, evidence for the efficacy of this technology is sparse, with some reviews suggesting it is the same or no better than conventional approaches. The purpose of this article is to provide real-world insights on the adoption of a virtual reality by 3 European clinics in 3 different service delivery models. These include an inpatient setting for Parkinson disease, a kiosk model for pediatric neurorehabilitation, and a home-based telerehabilitation model for neurologic patients. Motivations, settings, requirements for the pathology, outcomes, and challenges encountered during this process are reported with the objective of priming clinicians on what to expect when implementing virtual reality in neurorehabilitation.

Objective assessment of motor fatigue in Multiple Sclerosis using kinematic gait analysis: a pilot study.

BACKGROUND: Fatigue is a frequent and serious symptom in patients with Multiple Sclerosis (MS). However, to date there are only few methods for the objective assessment of fatigue. The aim of this study was to develop a method for the objective assessment of motor fatigue using kinematic gait analysis based on treadmill walking and an infrared-guided system. PATIENTS AND METHODS: Fourteen patients with clinically definite MS participated in this study. Fatigue was defined according to the Fatigue Scale for Motor and Cognition (FSMC). Patients underwent a physical exertion test involving walking at their pre-determined patient-specific preferred walking speed until they reached complete exhaustion. Gait was recorded using a video camera, a three line-scanning camera system with 11 infrared sensors. Step length, width and height, maximum circumduction with the right and left leg, maximum knee flexion angle of the right and left leg, and trunk sway were measured and compared using paired t-tests (α = 0.005). In addition, variability in these parameters during one-minute intervals was examined. The fatigue index was defined as the number of significant mean and SD changes from the beginning to the end of the exertion test relative to the total number of gait kinematic parameters. RESULTS: Clearly, for some patients the mean gait parameters were more affected than the variability of their movements while other patients had smaller differences in mean gait parameters with greater increases in variability. Finally, for other patients gait changes with physical exertion manifested both in changes in mean gait parameters and in altered variability. The variability and fatigue indices correlated significantly with the motoric but not with the cognitive dimension of the FSMC score (R = -0.602 and R = -0.592, respectively; P < 0.026). CONCLUSIONS: Changes in gait patterns following a physical exertion test in patients with MS suffering from motor fatigue can be measured objectively. These changes in gait patterns can be described using the motor fatigue index and represent an objective measure to assess motor fatigue in MS patients. The results of this study have important implications for the assessments and treatment evaluations of fatigue in MS.

Interrater reliability of the extended ICF core set for stroke applied by physical therapists.

BACKGROUND AND PURPOSE: The World Health Organization's International Classification of Functioning, Disability and Health (ICF) is gaining recognition in physical therapy. The Extended ICF Core Set for Stroke is a practical tool that represents a selection of categories from the whole classification and can be used along with the ICF qualifier scale to describe patients' functioning and disability following stroke. The application of the ICF qualifier scale poses the question of interrater reliability. The primary objective of this investigation was to study the agreement between physical therapists' ratings of subjects' functioning and disability with the Extended ICF Core Set for Stroke and with the ICF qualifier scale. Further objectives were to explore the relationships between agreement and rater confidence and between agreement and physical therapists' areas of core competence. SUBJECTS AND METHODS: A monocentric, cross-sectional reliability study was conducted. A consecutive sample of 30 subjects after stroke participated. Two physical therapists rated the subjects' functioning in 166 ICF categories. RESULTS: The interrater agreement of the 2 physical therapists was moderate across all judgments (observed agreement=51%, kappa=.41). Interrater reliability was not related to rater confidence or to the physical therapists' areas of core competence. DISCUSSION AND CONCLUSION: The present study suggests potential improvements to enhance the implementation of the ICF and the Extended ICF Core Set for Stroke in practice. The results hint at the importance of the operationalization of the ICF categories and the standardization of the rating process, which might be useful in controlling for rater effects and increasing reliability.
