Although yet poorly defined and often misused, the concept of functional mobility has been used in research studies as a more global and ecological outcome of patients’ health status. Functional mobility is a person’s physiological ability to move independently and safely in a variety of environments in order to accomplish functional activities or tasks and to participate in the activities of daily living, at home, work and in the community. Parkinson’s disease (PD) has a direct impact on patients’ motor control and on mobility in general. Even with optimal medical management, the progression of PD is associated with mounting impairments at different levels of body function, causing marked limitations in a wide variety of activities, as well as a severe disability and loss of autonomy. Despite this, for everyday functioning PD patients need to have a good functional mobility that allow them to get around effortlessly in a reasonable amount of time to access to the same environments as others. This paper reviewed the concept of functional mobility applied to PD. This was done through an International Classification of Functioning and Disability (ICF) perspective. Recommendations to address the known factors that contribute to a poor functional mobility were outlined while suggestions for clinical practice and research were made.

BackgroundOver the past decades there has been a significant increase in the number of published clinical trials in palliative care. However, empirical evidence suggests that there are methodological problems in the design and conduct of studies, which raises questions about the validity and generalisability of the results and of the strength of the available evidence. We sought to evaluate the methodological characteristics and assess the quality of reporting of clinical trials in palliative care.MethodsWe performed a systematic review of published clinical trials assessing therapeutic interventions in palliative care. Trials were identified using MEDLINE (from its inception to February 2015). We assessed methodological characteristics and describe the quality of reporting using the Cochrane Risk of Bias tool.ResultsWe retrieved 107 studies. The most common medical field studied was oncology, and 43.9% of trials evaluated pharmacological interventions. Symptom control and physical dimensions (e.g. intervention on pain, breathlessness, nausea) were the palliative care-specific issues most studied. We found under-reporting of key information in particular on random sequence generation, allocation concealment, and blinding.ConclusionsWhile the number of clinical trials in palliative care has increased over time, methodological quality remains suboptimal. This compromises the quality of studies. Therefore, a greater effort is needed to enable the appropriate performance of future studies and increase the robustness of evidence-based medicine in this important field.Electronic supplementary materialThe online version of this article (doi:10.1186/s12904-016-0181-9) contains supplementary material, which is available to authorized users.

Background Background: Exercise is gaining extreme relevancy as a new therapeutic intervention for Parkinson's disease (PD). However, the frequent misuse of the concepts exercise, physiotherapy, and physical activity limits the possibility of summarizing research findings. This review aims to clarify these concepts and summarize the evidence on exercise in PD. Methods Methods: We critically appraised physical activity-related concepts and conducted a systematic review of clinical trials evaluating exercise interventions in PD. Additionally, we discussed the implications for PD clinical practice and research. ResultsResults: Exercise is a subset of physical activity, and a major component of physiotherapy for PD management, having as the main goal to improve physical fitness. The appraisal of the 83 identified clinical trials found high variability in exercise interventions. Multimodal exercise was the most studied, and 60 minutes, two times/week for 12 weeks, the most reported prescription parameters. Conclusion Conclusion: The best available evidence recommends increasing physical activity levels in PD. Exercise and physiotherapy programs seem the most efficacious strategies to achieve this goal. As a result of the heterogeneity in the type and manner exercise is prescribed, it is not possible to propose strong recommendations for exercise in PD. We believe that, in addition to the clarification of concepts here presented, a collaborative and rigorous work of different areas of knowledge is needed.

Background: Gait impairments are common and highly disabling for Parkinson's disease (PD) patients. With the development of technology-based tools, it is now possible to measure the spatiotemporal parameters of gait with a reduced margin of error, thereby enabling a more accurate characterization of impairment. Objective: To summarize and critically appraise the characteristics of technology-based gait analysis in PD and to provide mean and standard deviation values for spatiotemporal gait parameters. Methods: A systematic review was conducted using the databases CENTRAL, MEDLINE, Embase, and PEDro from their inception to September 2019 to identify all observational and experimental studies conducted in PD or atypical parkinsonism that included a technology-based gait assessment. Two reviewers independently screened citations and extracted data. Results: We included 95 studies, 82.1% (n = 78) reporting a laboratory gait assessment and 61.1% (n = 58 studies) using a wearable sensor. The most frequently reported parameters were gait velocity, stride and step length, and cadence. A statistically significant difference was found when comparing the mean values of each of these parameters in PD patients versus healthy controls. No statistically significant differences were found in the mean value of the parameters when comparing wearable versus non-wearable sensors, different types of wearable sensors, and different sensor locations. Conclusion: Our results provide useful information for performing objective technology-based gait assessment in PD, as well as mean values to better interpret the results. Further studies should explore the clinical meaningfulness of each parameter and how they behave in a free-living context and throughout disease progression.
