Neck proprioceptive input, as elicited by muscle vibration, can produce destabilizing effects on stance and locomotion. Neck muscle fatigue produces destabilizing effects on stance, too. Our aim was to assess whether neck muscle fatigue can also perturb the orientation in space during a walking task. Direction and amplitude of the path covered during stepping in place were measured in 10 blindf...

Background Traditional muscle fatigue indices (Fmean and Fmed) have a relatively low sensitivity under dynamic exercise conditions. Various muscle fatigue indices have been attempted to overcome this problem [1,2]. However, their methods required large amounts of computation and had limitations in time-frequency resolution [3]. Kim et al. introduced the use of a filter-based fatigue index (FIhl...

background: fatigue can cause a significant effect on the mechanics of complex motor skills and reduce physical and mental efficiency. one of the common ways to reduce fatigue is passive recovering or using massage and cryotherapy after exercise. the present study aimed to compare the effects of massage and cryotherapy on muscles fatigue and isokinetic parameters. methods: this study was conduc...

Background: Multiple sclerosis (MS) is the most prevalent autoimmune chronic disease globally. The current study was conducted to determine the relationship between fatigue severity and circadian rhythm sleep disorders among Iranian MS patients.  Methods: The statistical population of this cross-sectional study included MS patients who were members of the MS Association in Khorramabad City, so...

INTRODUCTION Fatigue is a common and debilitating symptom in patients with multiple sclerosis (MS). Self-reported levels of perceived fatigue are associated with both patient characteristics and clinical measures. Pilot analysis indicated that muscle fatigability combined with depression scores was highly associated with perceived fatigue in patients with MS. Studies that combine physiological ...

A probabilistic approach of the current thermal fatigue design of nuclear components is set up. It aims at incorporating all kinds of uncertainties that affect the thermal fatigue behaviour. This approach is based on the theory of structural reliability. Two dual approaches of reliability analysis for the thermal fatigue are defined, respectively, in the time domain and in the frequency domain....

The pathophysiology of post-stroke fatigue is poorly understood although it is thought to be a consequence of central nervous system pathophysiology. In this study we investigate the relationship between corticomotor excitability and self-reported nonexercise related fatigue in chronic stroke population. Seventy first-time non-depressed stroke survivors (60.36 12.4 years, 20 females, 56.81 63 m...

We studied the effects of fatigue of the index finger on indices of force variability in discrete and rhythmic accurate force production tasks performed by the index finger and by all four fingers pressing in parallel. An increase in the variance of the force produced by the fatigued index finger was expected. We hypothesized that the other fingers would also show increased variance of their fo...
