Effects of Essence of Chicken on Physical Fatigue, Working Memory and Attention
Healthy SubjectsFatigueIn Southeast Asia, Essence of Chicken, a chicken-meat-extract, is a popular beverage and is consumed as a traditional remedy for several ailments, including the use as a nutritional supplement for sickness, enhancement of mental efficiency, and recovery from mental fatigue. While the elderly use it as a nutritional supplement, students use it for relief from anxiety during exam times. The present study is conducted in order to assess the effects of BEC on various physical and mental parameters including physical fatigue, working memory and attention, mood and stress, in comparison to placebo.

Multiple SclerosisRelapsing-RemittingThis is a study of Acthar gel (ACTH) in patients with relapsing multiple sclerosis who are experiencing chronic fatigue.

Acupuncture for Fatigue in Parkinson's Disease
Parkinsons DiseaseThis is a single-center, double-blind, placebo-controlled trial to see if acupuncture can safety and effectively treat fatigue in Parkinson's Disease (PD). Eligible subjects will receive either real or sham acupuncture twice weekly for six weeks.

Single Agent Armodafinil for Patient-Reported Fatigue Following Radiation Therapy for Head and Neck...
Head And Neck CancerFatigueThe goal of this clinical research study is to learn if armodafinil can reduce fatigue and other common symptoms in patients that have received treatment for head and neck cancer.

Pacing Activity Self-management for Patients With Chronic Fatigue Syndrome
Chronic Fatigue SyndromeGiven the lack of evidence in support of pacing self-management for patients with chronic fatigue syndrome (CFS), it is examined whether physical behavior and health status of patients with CFS improve in response to a pacing self-management program. The effects of pacing will be compared with those observed when applying relaxation therapy to patients with CFS.

Does Fampridine SR Improve Cognitive Fatigue in Multiple Sclerosis Patients?
Cognitive FatigueMultiple Sclerosis (MS) patients often complain of cognitive fatigue. There is currently no treatment for this symptom. Fampridine SR is a recently approved medication that improves walking ability and walking speed in MS patients. It is thought that it might have the same positive effect on cognitive fatigue. This study will compare fampridine 10mg twice a day to placebo in order to determine if there is any benefit of this medication for cognitive fatigue in MS.

The Effect of Sildenafil and Tadalafil on Skeletal Muscle and Perceptual Fatigue
FatigueThis study is funded by the Moody Endowment. In this project, we will investigate the potential effect of skeletal muscle nitric oxide (NO) production on skeletal muscle anabolism, muscle strength, physical function, and body composition in older individuals. Further, we will determine whether augmentation of NO-mediated signaling reduces fatigue and fatigability.

Trial of a Physical Activity Intervention for RA Fatigue
Rheumatoid ArthritisThe major goal of this project is to conduct a randomized, controlled trial of the impact of a practical, low cost physical activity intervention on fatigue among persons with rheumatoid arthritis (RA). Fatigue has been identified as a major concern for individuals with RA, and is considered a core outcome measure for RA. Our recent study of the sources of fatigue identified physical inactivity as a primary predictor of fatigue. Studies have examined the impact of exercise interventions on RA outcomes, but most of these interventions have focused on pain or function as outcomes. The few exercise studies examining fatigue suggest that increasing physical activity reduces fatigue, but the interventions have been resource-intensive, requiring specially trained personnel to administer them, highly structured activities, and/or attendance at classes or a specified facility. Each of these components increases the cost and barriers to implementation of an intervention. Pedometers have been shown to be an effective means of increasing physical activity, and could form the basis of a simple means to increase physical activity. This project will test the effect of a simple pedometer-based intervention, with two incremental degrees of guidance, on increasing physical activity and decreasing fatigue. Three groups (n=40 in each) will be studied: a control group with an educational pamphlet only, a pedometer-only intervention group, and a pedometer group with step targets. Both intervention groups will keep step-count diaries. Groups will be followed over 20 weeks. We expect that (1) the pedometer-only intervention group will increase activity more than the education group, and the group with step-count targets will demonstrate even greater increases in activity; and (2) greater increases in activity will be associated with greater decreases in fatigue. Secondary outcome measures will include depressive symptoms, self-reported sleep quality, and body composition. Our overall goal is to demonstrate an effective, yet simple and low cost, physical activity intervention to decrease fatigue that could be broadly accessible and have the potential for wide implementation.

Return to Work Randomized Controlled Trial: Counseling After Fatigue Treatment in HIV/AIDS
HIV InfectionFatigueThe current study is a randomized clinical trial comparing Behavioral Activation counseling with supportive counseling for HIV+ participants presenting with clinically significant fatigue whose energy has improved with armodafinil, who have the goal of returning to work or vocational training but have not done so on their own. A second cohort of HIV+ participants without significant fatigue at baseline, but who also have the goal of returning to work, will also be randomized to either Behavioral Activation counseling or supportive counseling. In both cohorts, the primary outcome is level of success regarding an employment related goal.

Evaluation and Training of Muscle Fitness in Pre-frail Individuals
FatigueMuscle strength and endurance are important indexes of fitness. The muscle strength is the most important single predict factor of functional ability in aged frail individuals. Frailty related muscle weakness and fatigue are adapted from the pre-frail stage. Finding the contributions of the central and the peripheral factors to the deficits of muscle fitness and developing an effective muscle fitness training program for pre-frail individuals are very important. The muscle weakness and fatigue can be categorized into peripheral or central causes. The central fatigue and voluntary activation failure originate from the decrease in motivation or the reduction of the conduction within corticospinal tracts. Long term activation failure and central fatigue will cause disuse of muscle and result in peripheral weakness and peripheral fatigue. Studies found the selective type II fiber atrophy in aged people and this finding was different from the type I atrophy in conventional immobilization models. It is possible that the activation failure leads to the recruitment failure of high threshold type II fibers at the pre-frail stage. Quantifying the weighting of central versus peripheral factors contributing to the exercise limitation in pre-frail people is important. Most of the conventional strength and endurance training programs are based on the researches of young groups. These programs are not able to prevent people become frail. It is possibly that, due to the limitation of central fatigue, the pre-frail individuals stop exercise before the effective intensity being achieved. Almost no training program has been design for enhancing the voluntary activation level and relief the central fatigue. Seeking an appropriate training program to enhance central activation at the pre-frail stage is very important for preventing people become frail. Previous studies have shown that increasing afferent input by peripheral electrical stimulation (ES) at sensory threshold enhanced the plasticity of contralateral primary sensory cortex, the excitability of corticospinal tracts, and the functional performance in young adults. ES, which is easy to quantify the dose of afferent input, is a feasible method to be used in training. Combining afferent input with strength training might be able to overcome the central activation failure and help recruit high threshold motor unit in pre-frail individuals.
