The purpose of this study is to develop new tools to understand surgeon performance to improve surgical training and participant outcomes after surgery.
This study will be an open-label trial to determine the functional effects of bilateral IA injections of Zilretta into knee joints of 70 subjects with bilateral KL grade 2-4 symptomatic knee osteoarthritis (OA). Measurement and evaluation of outcomes at baseline, 6, 12 and 24 weeks will allow assessment of short and long-term effects, consistent with Osteoarthritis Research Society International (OARSI) and Outcome Measures in Rheumatology (OMERACT) recommendations.
The project is intended to modify the Functional Independence Measure (FIM) for manual wheelchair users. It will determine if the new measure is a better measure of community independence for manual wheelchair users than the FIM. During the Phase 1 of the study it will then use this new measure to determine whether a home exercise program increases functional independence in wheelchair users. In Phases II and III of the study 120 manual wheelchair users will participate to test and validate the new measure and to test the effectiveness of therapeutic exercise. Subjects will range in age from 20 to 79 yrs. and have a variety of disabilities.
This study will examine how the supplement Shroom Tech Sport (STS) affects body composition and different performance and health measures over the course of 12 weeks. The supplement will be combined with a concurrent training regime consisting of resistance and high intensity interval training. Subjects will be tested for percent body fat to determine body composition. Further, they will also be tested for maximal strength (squat and bench), maximal power output and fatigue, lactate threshold and maximal oxygen volume consumption (VO2max). And finally, subjects will be tested for health and hormone markers in the blood. All of these measures will be compared against a placebo group participating in the same exercise intervention.
This research study will evaluate human performance and postural balance changes during the course of care with flexion distraction manipulation in multiple chiropractic practices.
This study investigates the computational mechanisms associated with psychiatric disease dimensions. The study will characterize the relationship between computational parameter estimates of task performance and psychiatric symptoms and diagnoses with a longitudinal approach over a 12 month interval. Participants will be healthy participants recruited through Prolific an on-line crowdsourcing service, and psychiatric patients and healthy participants recruited via UCLA Psychiatry Clinics and UCLA's STAND Program
AMATEA™ is a patented dietary supplement consisting of a unique blend of caffeine and polyphenol antioxidants; standardized at 20% caffeine, 30% chlorogenic acids (similar to green coffee). In-house evaluations and anecdotal findings related to AMATEA have noted sustained energy without the typical "crash" and/or "jitters" experienced by some with caffeine ingestion alone. The aim of the present study is to compare the effects of AMATEA and caffeine alone on various measures of cognitive performance, mood, and gaming performance in men and women who regularly engage in gaming activity. The investigators hypothesize that both AMATEA and caffeine will improve outcome measures more than placebo, with greater improvement noted for the AMATEA condition due to the addition of the chlorogenic acid.
The purpose of the study is to evaluate a new way to examine cardiac function, using software developed at Caltech. The experimental device is software loaded on an iPhone. The iPhone is used to capture a pulse (waveform) by simply placing the iPhone lightly over the neck where the carotid pulse can be felt. In this study the information collected from the iPhone app is compared to cardiac function data obtained from the current gold standard for measuring cardiac function, cardiac magnetic resonance imaging (MRI). Subjects referred from cardiologists will also generally have echocardiography information available for comparison with the iPhone app. For the study, subjects will have completely non-invasive studies done in one setting: The iPhone app to capture the waveforms (over carotid and radial (wrist) arteries), tonometry (another non-invasive method using a modified stethoscope), standard pulse oximetry, followed by a 30 minute MRI examination of the heart. A second complete study will be done about 6 months after the first. The complete study session takes about 1.5 hours.
The investigators' hypothesis is that therapy with Colesevelam, reduces fecal bile acid excretion in patients with Irritable Bowel Syndrome (IBS)-diarrhea with prior evidence of increased fecal 48 hour total bile acid excretion. The investigators aim to study the ability of the HPLC assay for fecal bile acids to demonstrate responsiveness after treatment with Colesevelam.
Oral Melatonin is a commercially available product available alone and as a constituent in a number of supplements. Previous research suggests that short-term supplementation with oral melatonin may amplify the recovery response to damaging resistance exercise via modulation of subsequent immune and inflammatory responses. However the effects of oral melatonin on neutrophil and monocyte invasion/migration, a critical step in the resolution of skeletal muscle tissue homeostasis, has not been examined. An oral melatonin supplement (5mg) will be provided three times daily beginning 24-hours before and ending 48-hours after an acute bout of damaging resistance exercise (total 15mg/day for 3 days). Goals: 1. To investigate the effect of melatonin on systemic and cellular responses following an acute bout of damaging resistance exercise. 2. To investigate the effect of melatonin on measures of functional performance before and during recovery from an acute bout of damaging resistance exercise.
Safety and Performance of Journey II BCS Total Knee System. A Retrospective, Multicenter Study. Patient Reported Outcome Measures.
The ID-Cap System is classified as an ingestion event marker (IEM), a Class II medical device. The system is intended to record time-stamped ingestions with the ingestible sensor, ID-Tag which transmits a signal to a wearable device, the ID-Cap Reader. In this study, 12-18 subjects will ingest capsules containing ingestible sensors while wearing the Reader and being observed in a clinic setting.
The main goal of this phase of the study is to determine if objectively assessed Physical Activity (PA) levels in advanced-cancer patients are associated with health care provider (HCP)-assessed ECOG performance status and overall survival. The purpose is to advance the evidence-base for incorporating objective assessment of Physical Activity (PA) in the context of performance status assessment in advanced cancer patients.
The purpose of this project is to explore the degree to which performance consistency on neuropsychological measures varies in a sample of Operation Iraqi Freedom (OIF)/Operation Enduring Freedom (OEF) Veterans with a history of mild traumatic brain injury (mTBI) with persistent self-reported symptoms.
This study will evaluate new assessment tools and equipment and new ways of using existing tools and equipment in the NIH Clinical Center s Rehabilitation Medicine Department in order to maximize patients function. The Department assesses and treats NIH patients with chronic pain, problems in walking or getting around, activities of daily living, performing tasks needed for jobs or hobbies, communicating and chewing and swallowing. Children and adults of all ages with disabilities and healthy normal volunteers may be eligible for this study. The following kinds of assessments are evaluated in this study: Assessments of Impairments Impairments are problems such as loss of movement, weakness or loss of sensation. Assessments may include measurements of range of motion, strength, sensation, pain, joint stability or mobility, joint angles, limb and girth, gait, exercise tolerance, stamina, or ultrasound imaging of muscle and swallowing function. Assessments of Function and Performance Functional and performance assessments look at how well subjects perform actions, such as walking or getting around, dressing, or preparing meals. They may include evaluations of activities of daily living, leisure activities, fatigue, vocational activity, school activity, coping skills, and quality of life. The assessments may be done by questionnaires or interviews and by watching subjects perform the activities. Assessments of Treatment Techniques Treatment techniques are assessed by evaluating methods and equipment used to treat patients with impairments or problems with function. They may evaluate, for example, the use of heat, cold, strengthening exercises, fitness exercises, TENS units, splinting and orthotics, or shoe modifications.
Automobile driving is a crucial aspect of everyday life, yet vehicular crashes represent a serious public health problem. Patients with epilepsy are at elevated risk for automobile crashes, causing great personal suffering and financial costs to society. Most collisions involving epileptic drivers are not seizure related but may instead result from cognitive effects upon driving performance of epilepsy and antiepileptic drugs (AEDs). Several million American drivers take AEDs for treatment of medical conditions besides epilepsy and may also be at risk for cognitive impairments that can reduce driving performance. Empirical evidence of the effects of AEDs on driving performance would enable development of driving guidelines that could lower the risk of injurious motor vehicle collisions; however, this evidence is currently lacking. The broad goal of our project is to determine the specific effects of the most commonly utilized AED, phenytoin, by assessing driving performance and cognitive abilities in neurologically normal volunteers taking phenytoin in a randomized, double-blind, placebo-controlled, crossover study. Our proposed experiments will assess: (1) cognitive functions using standardized neuropsychological tests (of attention, perception, memory, and executive functions), (2) driving performance during phenytoin and placebo administration, and (3) the effects of phenytoin-related cognitive performance upon driving performance. To measure driving performance, we will use a state-of-the-art fixed-base interactive driving simulator that allows us to observe driver errors in an environment that is challenging yet safe for the driver and tester, under conditions of optimal stimulus and response control. The results of this study of 30 drivers treated with phenytoin and placebo will increase the understanding of the role of AED-related cognitive impairment on driving safety errors. A better understanding of the impact of AEDs upon driving performance is necessary to rationally develop interventions that could help prevent crashes by drivers treated with AEDs.
The objective of this study is to determine the effects of a 6-month, home-based personalized transcranial direct current stimulation (tDCS) intervention targeting the left dorsolateral prefrontal cortex on cognitive function, dual task standing and walking, and other metrics of mobility in older adults with motoric cognitive risk syndrome (MCR).
