Fatigue

This proof-of-concept study aims to evaluate the feasibility, acceptability, and potential benefits of a novel multimodal approach: the micro-choice-based intervention.

This study aims to evaluate the effects of interval exercise on metabolic and inflammatory responses, energy substrate utilization, and fatigue in trained female basketball players. High-intensity intermittent exercise is a key component of basketball performance and induces substantial metabolic and physiological stress. However, the acute relationships between exercise-induced metabolic changes, inflammatory responses, substrate utilization, and fatigue in female basketball players remain insufficiently understood. In this prospective interventional study, eligible female basketball players will complete a standardized interval exercise protocol designed to replicate the physiological demands of competitive basketball. Physiological, biochemical, and perceptual measurements will be collected before exercise, immediately after exercise, and during recovery. Primary outcomes include changes in metabolic and inflammatory biomarkers, energy substrate utilization, and fatigue-related responses. Secondary outcomes include selected physiological and performance-related variables associated with recovery from high-intensity interval exercise. The findings of this study will improve the understanding of the physiological responses to interval exercise in female basketball players and may contribute to the development of evidence-based training and recovery strategies aimed at optimizing performance and athlete health.

This is a Phase 3, multicenter, randomized, double-blind, parallel-group, placebo-controlled clinical study to assess the efficacy and safety of HBS-301 in treating excessive daytime sleepiness (EDS), cataplexy, sleepiness/wakefulness, and fatigue in adult participants (ages ≥18 years) with narcolepsy.

The goal of this research study is to learn about the effects of the RISE-YA intervention on cancer-related fatigue in young adults who are brain cancer survivors.

Fatigue is the most common symptom reported by end-stage kidney disease patients on maintenance hemodialysis. Unfortunately, there currently is no medical management for this overwhelming feeling of tiredness. As a result, patients continue to suffer with poor quality of life and impaired daily activities. The purpose of this pilot trial is to find out if bupropion (a medicine commonly prescribed for stopping smoking, seasonal mood disorder, and depression) may help lessen fatigue in hemodialysis patients. In this study, hemodialysis participants will receive bupropion tablet orally three times a week during routine dialysis procedure for consecutive 8 weeks. Study participants will complete a battery of questionnaires to self-report fatigue, cognition, and quality of life. The study team will collect biological specimens. All these procedures will be performed at the dialysis clinic during routine dialysis procedure.

Taekwondo is a high-intensity combat sport characterized by repeated explosive kicking actions and rapid changes in body position, requiring well-developed postural control to maintain technical performance and reduce injury risk. Although fatigue has been reported to impair balance performance, previous studies have primarily induced fatigue using non-specific laboratory protocols that do not adequately reflect the physiological and neuromuscular demands of taekwondo competition. Consequently, the effects of taekwondo-specific fatigue on static and dynamic balance performance remain insufficiently understood. The primary objective of this study will be to investigate the effects of a taekwondo match-simulated fatigue protocol on static and dynamic balance performance in female taekwondo athletes. Eighteen competitive female taekwondo athletes will participate in this single-group repeated-measures study. Following a familiarization session, participants will complete a standardized taekwondo match-simulated fatigue protocol consisting of three 2-minute rounds separated by 1-minute passive recovery periods, replicating the official Olympic competition format. Static and dynamic balance performance will be assessed before and immediately after the fatigue protocol using the Biodex Balance System (Biodex Medical Systems Inc., Shirley, NY, USA). Balance performance will be evaluated under static and dynamic testing conditions, and the Overall Stability Index, Anteroposterior Stability Index, and Mediolateral Stability Index will be recorded. The findings of this study are expected to improve understanding of the acute effects of sport-specific fatigue on postural control in female taekwondo athletes and may contribute to the development of evidence-based training and injury prevention strategies.

The goal of this clinical trial is to learn if daily supplementation with a Nepalese Pepper Extract (Zanthoxylum Armatum, ZA) can improve cognitive performance and gaming performance in action video gamers aged 16 to 39, when taken over an extended period. The main questions it aims to answer are: Does chronic (42-day) daily ZA supplementation improve speed of cognitive performance and reduce subjective mental fatigue? Do these effects translate into objective and self-reported improvements in gaming performance? Are there additional acute (within-session) effects at the end of a chronic supplementation period, on top of any chronic effect? Researchers will compare 275mg daily ZA supplementation to placebo to see if chronic ZA produces better cognitive performance and lower fatigue than placebo. Participants will: Complete a screening call and a training visit on the computerised cognitive tasks and gaming tasks Take a daily capsule (either ZA or placebo, depending on treatment order) each morning with food for 42 days, then switch to the other treatment for a further 42 days after a 2-week washout Attend four testing visits at the research centre: a baseline and an endpoint visit for each 42-day treatment period Avoid alcohol and energy drinks for 24 hours before each testing visit, and caffeine from waking Complete cognitive tests before dosing and 1 hour after dosing at each testing visit Complete mood and sleep questionnaires Wear a heart rate monitor at rest on arrival at each visit Complete gaming-specific tasks (aim training, MOBA character control, multi-tasking, finger tapping, Fitts' Law, multiple object tracking, collision prediction) Play their action video game of choice at home throughout each 42-day period and complete performance questionnaires

Postpartum women frequently experience impairments in sexual function, pelvic floor dysfunction, fatigue, and depressive symptoms, all of which may adversely affect their quality of life during the postpartum period. Although pelvic floor muscle training is recommended as part of postpartum rehabilitation, evidence regarding comprehensive physiotherapist-led exercise programmes specifically targeting postpartum sexual health remains limited. Furthermore, no standardized telerehabilitation programme has yet been evaluated using a randomized controlled trial design. The aim of this randomized controlled trial is to evaluate the effectiveness of the POSH-Ex (Postpartum Sexual Health Exercise) programme, a standardized 12-week physiotherapist-led telerehabilitation intervention designed to improve female sexual function and overall postpartum health after childbirth. Secondary objectives are to evaluate its effects on pelvic floor muscle strength, physical activity, fatigue, depressive symptoms, health-related quality of life, and body composition. A total of 84 postpartum women will be randomly allocated in a 1:1 ratio to either the intervention group or the control group. Participants in the intervention group will complete supervised online exercise sessions twice weekly for 12 weeks, while participants in the control group will receive usual postpartum care. Outcome assessments will be performed at baseline and immediately after completion of the intervention. The primary outcome is female sexual function assessed using the Female Sexual Function Index (FSFI). Secondary outcomes include pelvic floor muscle strength, physical activity, fatigue, depressive symptoms, health-related quality of life, and body composition. The findings are expected to provide high-quality evidence regarding the effectiveness of a standardized telerehabilitation programme for postpartum rehabilitation and may contribute to the development of evidence-based postpartum rehabilitation programmes and future clinical practice guidelines.

This feasibility randomized controlled trial will assess the acceptability, feasibility, and preliminary effects of an integrated mindfulness and exercise eHealth intervention, eMindExCare, among prostate cancer patients undergoing active treatment in Hong Kong. Participants will be randomized in a 1:1 ratio to either an 8-week eMindExCare intervention or an enhanced health education attention-control programme. eMindExCare integrates culturally adapted Cantonese mindfulness practices with home-based aerobic and resistance exercise delivered through Zoom, supported by home practice, exercise logs, and weekly reminders. The enhanced health education control programme will match the intervention group in contact time and engagement but will not include progressive aerobic training, resistance-band prescription, stationary bike provision, or a structured mindfulness curriculum. Feasibility and acceptability outcomes will include eligibility, consent, randomization, attendance, retention, questionnaire completion, missing data, and adverse events. Preliminary outcomes will include sleep quality, fatigue, pain, physical activity, mindfulness, motivation for exercise, and quality of life assessed at baseline, immediately post-intervention at week 8, and 3 months post-intervention.

Radicle Women's Health DNSTM: A randomized, double-blind, placebo-controlled direct-to-consumer study assessing the impact of health and wellness products on fatigue and related women's health outcomes

Cancer-related fatigue (CRF) and cancer-related cognitive impairment (CRCI) are among the most commonly reported disabling symptoms experienced by patients with advanced cancer. However, there are currently limited evidence-based pharmacologic interventions available. The investigators will conduct a Vanguard Randomized Clinical Trial (RCT) to estimate the effect of modafinil in managing CRF and CRCI, and to test the feasibility of carrying out the study.

The purpose of this research study is to better understand how cancer-related fatigue affects patients and how it's discussed with providers. This information will be used to develop an educational resource (visual aid poster) that could help individuals and their providers talk about cancer-related fatigue and which may help individuals better manage this symptom.

Long COVID can cause persistent symptoms such as fatigue, cognitive difficulties commonly described as brain fog, reduced exercise tolerance, and impaired quality of life. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that may help modulate brain activity in regions involved in cognition, fatigue, and executive function. The NEUROSTIM-LC study will evaluate the feasibility and potential effects of repeated tDCS sessions in adults with long COVID presenting fatigue and/or brain fog. Participants will receive 30 sessions of tDCS applied over the left dorsolateral prefrontal cortex. Assessments will be performed before and after the intervention to evaluate changes in quality of life, fatigue, cognitive function, brain metabolism, physical performance, autonomic function, sleep quality, psychological symptoms, respiratory function, and blood biomarkers.

Systemic lupus erythematosus, or SLE, is a chronic autoimmune disease that can cause persistent fatigue, muscle pain, reduced physical function, and impaired quality of life, even when the disease is otherwise clinically stable. The biological mechanisms contributing to these symptoms are not fully understood. Abnormal energy production within skeletal muscle and increased fat accumulation within the muscle may contribute to fatigue and reduced physical performance in people with SLE. This pilot study will evaluate the effects of a 16-week personalized, home-based exercise program in 20 adults with stable SLE and clinically significant fatigue. The program will include three exercise sessions per week: bodyweight high-intensity interval training, strength training, and walking-based interval training. Sessions will be adapted to each participant's fitness, mobility, symptoms, and exercise tolerance. Some sessions will be supervised remotely by video, while others will be completed independently using personalized recorded instructions. Participants will undergo assessments before and after the 16-week program. These assessments will examine skeletal muscle mitochondrial function, fat accumulation within the thigh muscles, physical performance, fatigue, quality of life, and blood-based markers of mitochondrial function and inflammation. The study will help determine whether a personalized home-based exercise program can improve muscle health and physical function in people with SLE and will provide information needed to design larger future studies.

This study will make use of a cross-sectional design of MG patients and non-MG participants to quantitatively assess key MG symptoms, and to explore the applicability of machine learning algorithms to their measurement.

This study aims (1)to investigate the effects of repetitive functional overhead movements targeting shoulder and scapular muscles on glenohumeral and scapular kinematics and muscle activation during the arm cocking and acceleration of spiking, and changes in subacromial structures in healthy recreational volleyball players; (2) to compare these fatigue-related changes between athletes with good and poor shoulder motor control.

This randomized controlled trial aims to evaluate the effectiveness of virtual reality-guided imagery in reducing pain, anxiety, and fatigue among female breast cancer patients undergoing adjuvant chemotherapy. Participants will be randomly assigned to either an intervention group receiving virtual reality-guided imagery in addition to routine care, or a control group receiving routine care

Neuromuscular electrical stimulation (NMES) is widely used to improve muscle strength and mitigate atrophy. However, its clinical efficacy is often limited by early neuromuscular fatigue, muscle damage, and discomfort, which reduce patient tolerance and contraction time. Photobiomodulation (PBM) has emerged as a potential therapy to enhance muscle performance and accelerate recovery by minimizing fatigue and damage. Despite its potential, few studies have investigated the effects of PBM applied specifically before an NMES-evoked fatigue protocol. This randomized, double-blind, placebo-controlled trial aims to evaluate the acute effects of PBM on neuromuscular fatigue, muscle damage, and functional outcomes in healthy young subjects. Participants will receive either active PBM (cluster probe: 5 lasers 810nm/200mW; 4 LEDs 660nm/10mW; Total Energy: 249.6 J per limb) or sham treatment 5 minutes before a fatiguing NMES protocol (80 contractions at 20% MVIC, 80 Hz, 1ms pulse width) applied to the quadriceps muscle. Assessments will be performed at baseline, immediately post-intervention, and at 24h, 48h, and 72h post-intervention. Primary outcomes include maximum and evoked isometric strength, mechanical work, and electrical muscle activity. Secondary outcomes include muscle damage (ultrasound echo-intensity), delayed onset muscle soreness (DOMS), functional performance (unilateral vertical jump), and clinical discomfort. The study seeks to determine if PBM can effectively modulate NMES-induced fatigue and muscle damage, potentially optimizing its clinical application.

The primary objective of this study is to evaluate the safety and efficacy of Redsenol-1 Plus on cancer-related fatigue (CRF) in adults. The change in the severity of CRF from baseline at week 12 will be assessed by the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) fatigue subscale, and compared between Redsenol-1 Plus and placebo groups. Additionally, the safety and tolerability of Redsenol-1 Plus, as compared to placebo, will be measured by the occurrence of and/or changes in treatment-emergent adverse events (AEs).

The goal of this clinical trial is to evaluate whether Nuvastatic can reduce cancer-related fatigue in adult patients with colon cancer undergoing first-line chemotherapy. The main questions it aims to answer are: Does Nuvastatic significantly reduce cancer-related fatigue compared to placebo? Is Nuvastatic safe and well tolerated in this patient population? Researchers will compare Nuvastatic vs placebo to see if Nuvastatic improves fatigue scores and maintains an acceptable safety profile. Participants will: Receive Nuvastatic or placebo sachets (3 times per day) for 3 cycles of 20 days each (total \~60 treatment days). Continue their standard first-line chemotherapy regimen. Provide blood samples for biomarkers (CEA, CA-125) at Screening and End of Treatment. Complete patient diaries and fatigue assessments as per protocol.

The goal of this observational cross-sectional study is to investigate the relationship between functional measures of balance and gait and objective kinetic and kinematic parameters in people with Multiple Sclerosis (MS). The main questions it aims to answer are: i) What is the relationship between kinetic and kinematic gait and balance parameters measured using the Vicon motion analysis system and performance on clinical functional assessments in people with Multiple Sclerosis? ii) Which biomechanical parameters are most strongly associated with functional balance, gait, and physical performance outcomes? Participants will attend a single laboratory-based assessment session. During this session, they will undergo biomechanical gait and balance analysis using the Vicon motion capture system, complete functional assessments of balance, gait, and physical performance, complete questionnaires assessing fear of falling and fatigue, and undergo assessment of lower-limb spasticity.

As people grow older, it is common to experience a drop in physical stamina and memory functions. This can make recovering from daily physical and mental fatigue more difficult, which directly impacts an individual's independent daily life and overall quality of life. "Cognitive reserve" is a term that describes the brain's built-in resilience. Built over a lifetime through education, work, and social activities, a higher cognitive reserve acts like a buffer, helping the brain adapt to stress and aging. While research shows that a high cognitive reserve protects against conditions like dementia, we still do not fully understand how it helps older adults bounce back from normal, everyday physical and mental exhaustion. The goal of this study is to investigate how cognitive reserve levels influence how individuals aged 65 and older perceive their recovery after experiencing physical and mental fatigue. What the Study Involves The researchers will evaluate participants aged 65 and older to measure their baseline cognitive reserve levels. The study will look closely at how these levels affect the participants': Ability to cope with daily physical and mental fatigue. Need for rest and rest patterns. Time and ability to return to normal daily activities. Overall perception of their mental and physical recovery. Expected Outcome By understanding this relationship, the study aims to fill a gap in medical literature and help healthcare providers design better, more personalized rehabilitation and lifestyle support programs to improve the quality of life for older adults.

The primary objective of this study is to conduct a 16-week randomized controlled trial aimed at investigating the effectiveness of the Whole-Diet Approach when following a healthy US-style diet rich in anti-inflammatory properties. The study will focus on evaluating its impact on reducing symptoms related to Post-Acute Sequelae of SARS-CoV-2 Infection (PACS) in adults aged 50 years and older. The main research questions this study aims to answer are: 1. Does adhering to a healthy US-style diet, which is abundant in anti-inflammatory properties, effectively mitigate fatigue symptoms in adults with PACS? 2. Does adhering to a healthy US-style diet, which is abundant in anti-inflammatory properties, effectively mitigate declines in muscle function and physical performance in adults with PACS? At the beginning of the study, eligible participants will be randomly assigned to either the Dietary Intervention Group, where they will receive personalized dietary plans and weekly sessions, or the Attention Control Group, where they will attend general health sessions on a weekly basis as well. This research intends to shed light on the potential benefits of the Whole-Diet Approach and its role in ameliorating PACS-related symptoms among older adults. By comparing the outcomes of the two groups, we hope to gain valuable insights into the effectiveness of this dietary intervention in improving the quality of life for individuals dealing with PACS.

Newly graduated nurses often experience high levels of psychological stress, sleep disturbance, fatigue, and burnout during the early transition into clinical practice. Early identification of burnout and retention risk may help improve mental well-being, workforce stability, and quality of patient care. This longitudinal observational study aims to develop a non-invasive sleep-based prediction platform for assessing burnout and retention risk among postgraduate nurses. Participants will undergo repeated psychological assessments and non-contact sleep monitoring during the study period. Sleep-related physiological parameters, including sleep efficiency, sleep structure, heart rate variability, and respiratory variability, will be collected together with validated psychological questionnaires. The study will further apply machine learning and artificial intelligence approaches to integrate longitudinal physiological and psychological data for risk prediction and early identification of burnout-related conditions. The findings may support future development of precision mental health monitoring and supportive management strategies for high-stress healthcare workers.
