17 Clinical Trials for Various Conditions
The overall goal of this study is to attempt to overcome the organizational barriers that impede prompt screening for at-risk sensory deficits in childhood cancer survivors (CCS). Using a cross sectional design study, collaborators in the Informatics Research branch of the Institute of Informatics at the Washington University School of Medicine will identify CCS at risk for sensory deficits based upon their therapy exposure to generate the highlighting patients at risk for sensory screening (HPARSS) document. The investigators will utilize the HPARSS that will link therapy related risks for sensory deficits to specific screening procedures prompting the primary oncology provider to implement screening, diagnostic testing, and therapy.
Aim 1: To use magnetoencephalography (MEG) and magnetic resonance imaging (MRI) in Veterans and civilians with mild traumatic brain injury (mTBI) and sensory postconcussive symptoms (PCS) to demonstrate the mechanism of therapeutic benefit of HD-tDCS for sensory symptoms, as shown by reliable changes in the activity of the cognitive control network (CCN) and sensory system network (SSN) following stimulation; Aim 2: this intervention will result in long-term improvements in measures of executive function, depression/anxiety, and quality of life.
To determine changes in thigh muscle function and knee pain after a partial meniscectomy surgery and to also determine the effects of applying electrical stimulation to the knee to determine if this improves thigh muscle function and decreases pain.
The primary objective of this new line of research is to test whether augmenting sensory information from the legs, using Walkasins sensory neuroprosthesis, can enhance performance of a complex walking task in older adults with foot sensory impairment. The overarching hypothesis is that Walkasins will enhance the automaticity and reduce cognitive demand of walking in older adults with foot sensory impairments, as measured by reduced prefrontal activity, decreased dual-task costs, and lower gait variability.
Few studies have used quantitative sensory tests to study the effect of chronic opioid treatment on sensation. The investigators will test chronic pain patients who are on different MEDDs, normal volunteers, and patients undergoing an opioid taper. This will be the first study to perform sensory testing on patients while undergoing an opioid taper on an outpatient basis.
Introduction Fascia Iliaca compartment block (FICB) is commonly used to treat pain in patients after total hip arthroplasty (THA) despite the lack of RCTs to evaluate the efficacy of FICB for this indication. Therefore the objective of this study was to assess the analgesic benefit of FICB for post-operative pain management in THA. Methods After IRB approval and informed consent, patients having THA at our center in the period 2010-2011 were recruited. Eligible patients were adults, ASA physical status I-III, and BMI \<30) with no contraindication to study procedures. In the PACU, all patients received morphine sulfate IVPCA; patients reporting pain \> 3 on the NRS-11 despite IVPCA were randomized by the method of sealed envelopes to receive US guided injections of 30ml 0.5% ropivacaine (FICB) or 30ml 0.9% NaCl (sham block, SB) beneath the fascia iliaca. The primary outcome variable was opioid analgesic consumption during the first 24 h postoperatively. Secondary outcome measures were pain intensity (NRS-11) and extent of sensory blockade.
Stroke affects over 795,000 Americans every year and has an enormous impact on the well-being of American Veterans with 6,000 new stroke admissions every year. Many of these stroke survivors are living with disabilities that limit their everyday function. One of the major consequences of stroke is loss of sensation which manifests as inability to perceive touch, temperature, pain or limb movement. Lack of sensation hinders full functional recovery. Current treatments for sensory loss produce only limited improvements and do not achieve full recovery. Therefore, it is critical to develop new therapies to re-train sensory function. The investigators propose to evaluate a novel non-invasive brain stimulation treatment called repetitive Transcranial Magnetic Stimulation (rTMS). The effects of this technique on motor deficits following stroke have been studied, however rTMS for the treatment of sensory loss has not been examined to date. The investigators' study will examine for the first time if rTMS of a sensory brain region can improve sensory function in chronic stroke survivors.
The purpose of this study is to investigate how sensory information processing affects balance ability in children with cerebral palsy (CP). An additional goal is to determine if a subsensory electrical stimulation called Stochastic Resonance (SR) Stimulation, can improve balance in children with CP. Children with CP and children with typical development will participate and complete a series of clinical and balance assessments. They will also be tested in a sensor fusion paradigm to investigate potential deficits in the dynamic integration of visual, vestibular and proprioceptive information during upright stance. SR stimulation will then be used to potentially improve these deficits and subsequently their balance ability.
The purpose of this study is the use of magnetoencephalography or MEG (a machine that measures magnetic activity in your brain) and electroencephalography or EEG (a technique that measures electrical activity in your brain) to study how sounds are processed in individuals with schizophrenia prior to initiation with aripiprazole treatment and after three months of taking the antipsychotic medication aripiprazole.
The purpose of this study is the use of magnetoencephalography or MEG (a machine that measures magnetic activity in your brain) and electroencephalography or EEG (a technique that measures electrical activity in your brain) to study how sounds are processed in individuals with schizophrenia after three months of taking the antipsychotic medication quetiapine.
The objective is to evaluate if neuromodulation of the PFC can acutely improve sensory integration for balance performance in OTTBCS.
The goal of this study is test the hypothesis that sleep problems for children with ADHD are linked to sensory over-responsivity, a type of sensory processing difference that causes a person to interpret daily sensory input as stressful. This study examines the impact of sensory over-responsivity on bedtime arousal levels in 30 children with ADHD (ages 6-13). We will also test a bedtime intervention targeting sensory over-responsivity at bedtime and examine how it impacts bedtime arousal levels and sleep difficulties.
Parkinson's disease (PD) impacts different types of neural oscillations in the brain, including beta (13-30Hz) and gamma oscillations (30-80Hz), which contributes to PD's cardinal symptoms of resting tremor, rigidity, bradykinesia (slowness of movement), and gait instability. The investigators' lab has developed a non-invasive method of increasing gamma power in the brain using Gamma Entrainment Using Sensory Stimulation (GENUS) through light, sound, and tactile stimulation devices. For this study, 40 participants with mild Parkinson's disease will be recruited, and the investigators will assess their brain waves with electroencephalogram (EEG) before, during, and after light, sound, and tactile stimulation to determine the safety, feasibility, and optimization of GENUS as a potential therapy in the PD population.
The purpose of this pilot study is to determine the effects of 15 minutes of sensory-play based (SenPlay) intervention on improving focused attention in developmentally appropriate tasks in young children with or at risk for ADHD.
The long-term goal of this project is to develop a non-invasive, noise-based technique for enhancing somatosensation and thereby improving balance control in elderly fallers and older adults with somatosensory deficits.
Many critically ill newborns in the neonatal intensive care (NICU) or critical care unit (NCCU) environment develop feeding and movement problems. The purpose of this study was to determine the extent to which neurophysiologically based occupational therapy intervention (NBOTI) for NCCU infants would affect the intervention group's oral feeding and other covariates, such as heart rate variability (HRV) during feeding. The biopsychosocial model provided the study's conceptual framework. The key research question explored whether NBOTI in the NCCU promoted healthy infant development through feeding, movement organization, and parent self-efficacy. This exploratory study with 10 NCCU infants and 10 historical matched controls utilized a mixed method design of qualitatively coded video analysis and inferential statistics such as the t test, the binomial test, hierarchal linear modeling (HLM), and multivariate analysis. Significant differences were obtained between the intervention and comparison groups in the number of days from all tube to all oral feeding before discharge and speed at which the infants gained weight. Longitudinal analyses of the intervention group data were employed to reveal significant trends and pre/post differences in the HRV data along with how quickly the infants ate, parent perceptions of self efficacy and decreased stress in the NCCU. Finally, qualitative findings obtained from videotape analysis provide further evidence that NBOTI was effective in facilitating feeding and promoting development. The recommendations are to replicate this study to validate and expand the findings of the current study. The model for infant care suggested by the findings could contribute to positive social change by fostering positive physical and emotional child development and healthy child-parent and family-caregiver relationships.
Magnetic resonance imaging (MRI) is a diagnostic tool that creates high quality images of the human body without the use of X-ray (radiation). MRI is especially useful when studying the brain, because it can provide information about certain brain functions. In addition, MRI is much better than standard X-rays at showing areas of the brain close to the skull and detecting changes in the brain associated with neurological diseases. In this study researchers will use MRI to gather information about the processes that control human movement and sensory processing. The purpose of the study is to investigate how the brain is activated when remembering, thinking, or recognizing objects. Researchers would like to determine what happens to brain functions when patients have trouble remembering, thinking, or recognizing objects following the start of disorders in the brain and nervous system. In addition, this study will investigate the processes of motor control in healthy volunteers and patients with disease.
