5 Clinical Trials for Various Conditions
Traumatic Brain Injury (TBI)patients often suffer from loss of muscle strength in the hand and foot, decrease in coordination and high muscle tone (spasticity). In this study, investigators seek to compare how two different training programs can improve the coordination and symptoms of fatigue in individuals with movement deficits secondary to TBI. Using brain imaging, the study will also investigate changes in brain structure and activity associated with hand movement.
Individuals with chronic stroke have long-term walking problems that limit community engagement and quality of life, lead to secondary disabilities, and increase healthcare costs and burden. These walking issues often persist despite rehabilitation. One novel target for stroke gait rehabilitation is interlimb coordination-the phase-dependent cyclical relation of the legs. Interlimb coordination is altered during walking after stroke, compromising walking stability, phase transitions, and responses to perturbation and contributing to motor compensation. It is unclear what neural pathways contribute to impaired interlimb coordination after stroke and what impact this has on walking-related outcomes. This proposal consists of two aims to address these issues, with the long-term goal of developing therapeutic interventions to improve interlimb coordination and walking after stroke. Aim 1 will identify which neural sources contribute to impaired interlimb coordination after stroke. During bilateral, cyclical recumbent stepping (analogue of walking), interlimb coordination will be assessed as relative leg phasing. During the task, transcranial magnetic stimulation and peripheral nerve stimulation will be applied to assess supraspinal, interhemispheric, spinal interneuronal, and sensory pathways. The relation of interlimb coordination with these outcomes will be assessed to determine potential contributors. Aim 2 will test the association between interlimb coordination and walking after stroke. Interlimb coordination will be quantified during split-belt treadmill walking, and associations with walking speed, endurance, mobility, independence, daily activity, quality of life, and community engagement will be tested. An additional exploratory aim will determine the effect of targeted neuromodulation on lower limb interlimb coordination. Electrical stimulation will be applied to three locations in a cross-over study: the primary motor cortex (supraspinal/interhemispheric), thoracolumbar spine (spinal interneuronal), and peripheral nerves (sensory).
Aim 1. To compare across three hospital sites the effects on health and cost outcomes observed by the following three interventions, each designed to enhance adaptation and improve outcomes of hospitalized cognitively impaired elders and their caregivers: 1. augmented standard care (ASC) - standard hospital and, if referred, home care plus early identification of CI during the patients' hospitalization by trained registered nurses (RNs) with immediate feedback to patients' primary nurses, attending physicians and discharge planners; 2. resource nurse care (RNC) - standard hospital and, if referred, home care plus early identification of CI during the patient's hospitalization by trained RNs and hospital care by RNs trained in the use of expert clinical guidelines developed to enhance the care management of hospitalized cognitively impaired elders and to facilitate their transition from hospital to home; or, 3. advanced practice nurse care (APNC) - standard hospital care plus transitional (hospital to home) care substituting for standard home care and provided by APNs with advanced training in the management of CI patients using an evidence-based protocol designed specifically for this patient group and their caregivers. \[H1\] We hypothesize that health and cost outcomes with APNC, a comprehensive intervention designed to meet the unique needs of cognitively impaired older adults hospitalized for an acute medical or surgical event and their caregivers will be associated, relative to health and cost outcomes with ASC and RNC, with improvement in patient, caregiver and cost outcomes. \[H2\] We hypothesize that improvements in patient, caregiver and cost outcomes observed for the RNC group will be greater than those observed for the ASC group. Aim 2. To compare within each site and over time, health and cost outcomes (identified in Aim 1) from patients treated with either ASC or RNC, both relatively lower intensity interventions, with the outcomes of patients at the same site observed after switching to APNC, a high intensity intervention. \[H3\] We hypothesize that compared to patients receiving the ASC or the RNC interventions, patients at the same site will have improved patient, caregiver and cost outcomes after the site switches to APNC. \[H4\] We hypothesize that patient, caregiver and cost outcomes achieved by the groups receiving APNC interventions at T1 and T2 will be similar.
The research is aimed at developing and testing a new method of visual-motor rehabilitation of Veterans with macular degeneration by using inexpensive "tablet" computers at home.
The purpose of this study is to determine whether a home care medication management program which includes nurse coordination and use of the MD.2 medication-dispensing machine will affect older adults' health outcomes, satisfaction, use of health care services, and health care costs over a one year period. The investigators propose a longitudinal three group repeated measures design, enrolling, and randomly assigning, clients who are discharged from a home health care agency with documented problems in medication management. One group will receive the MD.2 medication dispensing device and nurse coordination, the second group will receive a Medplanner: a simple box that has separate compartments for individual medication times over the course of a week plus nurse coordination, and the final group will receive Usual Care. The study hypotheses are the following: H1: With respect to health status outcomes, the MD.2 group will exhibit a more positive trajectory in physical and mental health status, functional status, cognitive status and depressive symptoms over the course of a year than will the Medplanner Group. H2: With respect to health status outcomes, the Medplanner Group will exhibit a more positive trajectory in physical and mental health status, functional status, cognitive status and depressive symptoms over the course of a year than will the Usual Care Group. H3: The rate of hospitalization, hospital days and emergency department visits will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H4: The rate of hospitalization, hospital days and emergency department visits will be significantly lower for the Medplanner Group as compared to the Usual Care Group. H5: The nursing home admission rate will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H6: The nursing home admission rate will be significantly lower for the Medplanner Group as compared to the Usual Care Group. H7: The total cost of care will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H8: The total cost of care will be significantly lower for the Medplanner Group as compared to The Usual Care Group. H9: There will be incremental savings in terms of costs per quality adjusted life year (QALY) gained in the MD.2 group compared with the Medplanner Group. H10: There will be incremental savings in terms of costs per QALY gained in the Medplanner group compared with the Usual Care Group.
