The objective of this study is to identify key indicators in the follow-up of subjects with different pathologies related to both the person's environment, as well as the perception of their health and general quality of life and related to their disease. To this end, a cross-sectional observational study of qualitative data collection through questionnaires, mostly validated, has been proposed to try to identify these indicators. Based on these questionnaires, the specific objectives of this study are as follows: - Unify questionnaires - Assess data quality - Identify key indicators, through a factor analysis - Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. In order to identify the key indicators, it will be necessary to measure at least 30 subjects from each pathological group, as well as a cohort of at least 100 subjects without pathologies in order to validate and contrast the results. The subjects will be recruited through the own databases of participants in previous trials of the Institute of Biomechanics of Valencia, who have given written consent to be contacted in order to request their participation in any other study where their profile may fit. They will also be recruited and contacted through the collaborating associations (Parkinson Valencia Association, Valencian Diabetes Association, Consorci Hospital General Universitari de València, Arnau de Vilanova Valencia Hospital). The surveys will be included in an online platform specialized in the realization of questionnaires. This data will be exported for further storage, management and analysis. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. To participate in the study, participants must accept the terms and conditions included in the first page of the survey embedded in the online platform, where the aspects related to the study methodology and the use of them data are exposed. The statistical analysis will treat the data provided by the variables and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. For that, non-parametric techniques such as the χ² test, the Kruskal-Wallis test and cluster analysis will be used.
To examine the revascularization efficacy and safety of T-02 and its associated performance characteristics in treatment of appropriately selected subjects experiencing an acute ischemic stroke when the treatment is initiated within 24 hours after last seen well under the current guideline, and to generate hypotheses to be confirmed in subsequent confirmatory clinical investigations
To determine whether treatment with transauricular vagus nerve stimulation (taVNS) during the training of an affected upper limb of a patient with chronic stroke on a robotic motor task alters the motor impairment.
This study aims to compare the effects of mental imagery and virtual reality training with virtual reality alone on lower limb functional status of stroke patients. The study will be a randomized controlled trial. After the initial evaluation randomization will be done on participants lying under the eligibility criteria. Randomized participants will be allocated to Control & Experimental groups. Mental imagery (Audiotape recordings of some specific tasks for lower limb functions) with Virtual reality training given to experimental group while Virtual reality training alone to Control group. Task oriented training for balance & gait as baseline treatment will be given to each group.
VERIFY will validate biomarkers of upper extremity (UE) motor outcome in the acute ischemic stroke window for immediate use in clinical trials, and explore these biomarkers in acute intracerebral hemorrhage. VERIFY will create the first multicenter, large-scale, prospective dataset of clinical, transmagnetic stimulation (TMS), and MRI measures in the acute stroke time window.
The loss of upper-limb motor functioning due to ischemic stroke has a negative impact on quality of life of patients. Action Observation Treatment (AOT), recently developed based on the mirror mechanism functioning, has proved effective in promoting plasticity into the motor system, ultimately boosting the motor recovery. The use of virtual reality further empowers the effectiveness of AOT, making the visual experience more first-person, and thus more realistic. A complete picture of the neurobiological mechanisms underlying AOT effectiveness is lacking to date, including the neuroradiological and biohumoral markers modulated by AOT, and their role in predicting the clinical outcome. Starting from these premises, the investigators propose a study aiming at evaluating the AOT effectiveness in post-stroke patients, and at identifying the biomarkers indexing the motor recovery process. Sixty patients affected by ischemic stroke will be enrolled at Humanitas Clinical and Research Center IRCCS (ICH) Stroke Unit will be included and randomized in the following groups: - VR-AOT: experimental group, observing actions in virtual reality - VR-LO: control groups, observing a matched dose of videos depicting landscapes in virtual reality. Clinical, neuroimaging and biohumoral evaluations, performed at Screening (Ts), Basal visit (T0), end-of-treatment (T1), 2 months follow up (FU-2), will include the following endpoints: Fugl-Meyer upper extremity motor scale (FM-UE); Nine-hole-peg test; Box and block test; Modified Ashworth scale; MRC; Pain Numeric-rating-scale; Functional Independence measure. Patients will undergo treatment sessions for 6 weeks (5 days/week). VR-AOT patients will observe in virtual reality -rehearse and execute specific upper limb motor task belonging to activities of daily living. VR-LO participants will observe virtually explorable landscapes lasting for a matched duration. Then, participants will be asked to actively perform the same set of hand actions requested to VR-AOT experimental groups. An intention-to-treat (ITT) analysis will be performed, using rmANOVA, minimal clinically important difference (MCID) in clinical outcomes, and chi-square test. For the primary endpoints, a two-arms rmANOVA with time as within-subject factor (3 levels: T0, T1, FU2) and group (VR-AOT vs VR-LO) as between-subjects factor will be conducted. The same approach will be adopted for secondary outcome measures. Subsequently, the effect of clinical, neuroradiological and biohumoral baseline features will be tested as regressors on the primary outcome variations via linear or ranked regression models. Significance will be set at 5%, and adjusted for MC.
Further studies are needed to provide more detailed information on the potential effects of robotic gait training in general, as well as on the influence on gait movement patterns in particular. Patient perspectives and feedback contribute to the continuous development of exoskeletal technology. For these reasons, the main objective of this study is to decipher the relationship between EksoNR's robotic control settings and walking biomechanics in stroke patients and healthy subjects; the second objective is to discover the user experience during the use of EksoNR.
The purpose of this study is to study the effect mechanism of programmed flexor-extensor alternating electrical acupiont stimulation on upper limb functional reconstruction after stroke.
Perioperative stroke is a devastating complication of cardiac surgery that is currently poorly characterized but occurs in 1-5% of patients and is associated with poor outcomes including increased mortality. Given the uncommon nature of this complication, relatively little is known about which factors predict these outcomes among those who experience a perioperative stroke. The study objectives are to identify predictors of mortality, length of stay and discharge disposition after perioperative stroke in cardiac surgery using the prospectively-collected American College of Surgeons National Surgical Quality Improvement Program database between 2005 and 2020.
