Background: Bojungikki-tang (Bu-Zhong-Yi-Qi-Tang in Chinese or Hochu-ekki-to in Japanese) is a widely used herbal prescription in traditional medicine in China, Japan, and Korea. The aim of this study was to investigate the effectiveness of Bojungikki-tang for cancer-related fatigue. Methods: A total of 40 patients with cancer-related fatigue were randomized into an experimental or a waiting li...

CONTEXT As individuals returning to activity after anterior cruciate ligament reconstruction (ACLr) likely experience fatigue, understanding how fatigue affects knee-muscle activation patterns during sport-like maneuvers is of clinical importance. Fatigue has been suggested to impair neuromuscular control strategies. As a result, fatigue may place ACLr patients at increased risk of developing p...

Objectives. Pittsburgh Sleep Quality Index (PSQI) values correlate with depression, but studies investigating the relationship between PSQI values and polysomnographic (PSG) data showed inconsistent findings. Methods. Sixty-five consecutive patients with multiple sclerosis (MS) were retrospectively classified as "good sleepers" (GS) (PSQI ≤ 5) and "poor sleepers" (PS) (PSQI > 5). The PSG data a...

BACKGROUND The Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 instrument (MDF-Fibro-17) has been developed for use in fibromyalgia (FM) clinical studies and includes 5 domains: Global Fatigue Experience, Cognitive Fatigue, Physical Fatigue, Motivation, and Impact on Function. Psychometric properties of the MDF-Fibro-17 needed to demonstrate the appropriateness of using this instrument ...

Two efficient methods for time-dependent fatigue reliability analysis are proposed in this paper based on a random process representation of material fatigue properties and a nonlinear damage accumulation rule. The first method is developed by matching the first two central moments of the accumulated damage to a well-known probability distribution, thus facilitating direct analytical solution o...

Poor sleep is a serious burden for patients with multiple sclerosis (MS). The aim of this study is to assess whether the association between sleep quality and disability in MS patients is direct or mediated by depression, pain, and fatigue. We collected data from 152 patients with MS who filled out the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, the Multidimension...

Salivary biomarkers have been increasingly popular in stress research as saliva is easily produced and collection is non-invasive and not limited by geographical distance or lack of infrastructure. Several salivary biomarkers have been utilized in stress research, for instance, salivary cortisol, salivary amylase and salivary immunoglobulin A. Despite being sensitive to changes in fatigue, they...

BACKGROUND Fatigue is a common and debilitating symptom in multiple sclerosis (MS). Best-practice guidelines suggest that health services should repeatedly assess fatigue in persons with MS. Several fatigue scales are available but concern has been expressed about their validity. The objective of this study was to examine the reliability and validity of a new scale for MS fatigue, the Neurologi...

BACKGROUND People with multiple sclerosis (MS) often report poor sleep, fatigue, sleepiness, depression and cognitive dysfunction. Interrelationships between symptoms and sleep are poorly understood. OBJECTIVES To document objective parameters of sleep measured by polysomnography (PSG) and multi-sleep latency tests (MSLTs) in patients experiencing fatigue or sleepiness and to determine whethe...

Healthy untrained men performed 10 series of 12 knee eccentric extension repetitions (EE) at 160 degrees /s. The maximal voluntary isometric contraction force of the quadriceps muscle, the maximal rate of electrically induced torque development (RTD) and relaxation (RTR), isokinetic concentric torque at 30 degrees /s, the electrostimulation-induced torque at 20 and 100Hz frequencies were establ...
