Fatigue fracture of a DBS extension cable: a pictorial review.

Non-deep brain stimulation (DBS) lead hardware complications are quite uncommon. They are observed more with tremor and dystonia patients due to constant strain on the neck region. However, occurrence of such complication over a two-decade period has not been reported. Twenty years after DBS implantation, a patient presented with a wear and tear fracture in the extension cable, which we describe as a fatigue fracture of the extension cable. Delayed hardware complications following DBS implantation is an under-reported entity due to follow-up compliance over the long term. Reporting such compli…

[Sport and exercise therapy for burnout and fatigue-a narrative review].

Burnout and fatigue have overlaps in their symptoms. The common denominator is exhaustion. Physical activity has been shown to be a risk-reducing factor for the development or manifestation of symptoms. There is also evidence of an effect of physical activity in the acute phase, rehabilitation, and aftercare of burnout as well as in diseases that are associated with the occurrence of fatigue and their treatments.In burnout research, physical activity is considered a risk-reducing factor and coping strategy, but there are no specific exercise recommendations with regard to symptom severity. In …

[Wakefulness-promoting agents for severe fatigue: to use or not to use?].

About 20% of adults experience excessive daytime sleepiness or severe fatigue. Causes include somatic conditions, psychiatric disorders, and medication or drug use. Treatment depends on the underlying cause. If sleepiness persists despite optimal treatment of the underlying condition, exclusion of other causes, and behavioral interventions, wakefulness-promoting agents may be considered. However, no established pharmacological strategy exists for symptomatic treatment. Modafinil and stimulants like methylphenidate may offer some benefit based on experiences with narcolepsy or idiopathic hypers…

Comments on: Effect of physical activity on long COVID fatigue.

The authors of the Comments on: Effect of physical activity on long COVID fatigue by Daungsupawong F. and Wiwanitkit V. (2023) have highlighted certain aspects of future research that need to be considered before any conclusions can be drawn regarding the effect of previous physical activity and/or fitness on the course of long-COVID. We can only agree with this need, although we hope that the effects of SARS-CoV-2 infection will become less and less burdensome to manage. As we hypothesise in the last part of the article by Coscia et al. (2023), we think it is crucial to identify the molecular…

Effects of induced motor fatigue on walking mechanics and energetics.

Lower-body robotic exoskeletons can be used to reduce the energy demand of locomotion and increase the endurance of wearers. Understanding how motor fatigue affects walking performance may lead to better exoskeleton designs to support the changing physical capacity of an individual due to motor fatigue. The purpose of this study was to investigate the effects of motor fatigue on walking mechanics and energetics. Treadmill walking with progressively increased incline gradient was used to induce motor fatigue. Twenty healthy young participants walked on an instrumented treadmill at 1.25 m/s and …

Factor Analysis of Fatigue in the Early Stages of Cancer Chemotherapy.

Patients undergoing chemotherapy for cancer frequently experience fatigue, which can significantly lower their quality of life and interfere with treatment. However, the risk factors for the occurrence of chemotherapy-induced fatigue (CIF) are unclear. In this study, we investigated the occurrence of CIF in 415 patients newly treated with chemotherapy at Fukuoka University Hospital between December 2020 and July 2022, and analyzed the factors that influence the occurrence of fatigue. The observation period was defined as the two-week period starting from the day after the induction of chemothe…

Trunk stability in fatiguing frequency-dependent lifting activities.

BACKGROUND: Work-related low-back disorders (WLBDs) are one of the most frequent and costly musculoskeletal conditions. It has been showed that WLBDs may occur when intervertebral or torso equilibrium is altered by a biomechanical perturbations or neuromuscular control error. The capacity to react to such disturbances is heavily determined by the spinal stability, provided by active and passive tissues and controlled by the central nervous system. RESEARCH QUESTION: This study aims to investigate trunk stability through the Lyapunov's maximum exponent during repetitive liftings in relation to

A continuum damage model of fatigue and failure in whole bone.

Predicting the fatigue failure of whole bone may provide insight into the etiology of stress fractures and lead to new methods for preventing and rehabilitating these injuries. Although finite element (FE) models of whole bone have been used to predict fatigue failure, they often do not consider the cumulative and nonlinear effect of fatigue damage, which causes stress redistribution over many loading cycles. The purpose of this study was to develop and validate a continuum damage mechanics FE model for the prediction of fatigue damage and failure. Sixteen whole rabbit-tibiae were imaged using…

Fatigue Response of MoS2 with Controlled Introduction of Atomic Vacancies.

Fatigue-induced failure resulting from repetitive stress-strain cycles is a critical concern in the development of robust and durable nanoelectromechanical devices founded on 2D semiconductors. Defects, such as vacancies and grain boundaries, inherent in scalable materials can act as stress concentrators and accelerate fatigue fracture. Here, we investigate MoS2 with controlled atomic vacancies, to elucidate its mechanical reliability and fatigue response as a function of atomic defect density. High-quality MoS2 demonstrates an exceptional fatigue response, enduring 109 cycles at 80% of its br…

This is an updated version of the original Cochrane Review published in Issue 4, 2016. OBJECTIVES: To assess the effectiveness and safety of pharmacological and non-pharmacological interventions for adults with PBT and clinically significant (or high levels) of fatigue. SEARCH METHODS: For this updated review, we searched CENTRAL, MEDLINE and Embase, and checked the reference …

Disruptions in Structural and Functional Connectivity Relate to Poststroke Fatigue.

Introduction: Poststroke fatigue (PSF) is a disabling condition with unclear etiology. The brain lesion is thought to be an important causal factor in PSF, although focal lesion characteristics such as size and location have not proven to be predictive. Given that the stroke lesion results not only in focal tissue death but also in widespread changes in brain networks that are structurally and functionally connected to damaged tissue, we hypothesized that PSF relates to disruptions in structural and functional connectivity. Materials and Methods: Twelve patients who incurred an ischemic stroke…

Critical considerations of the contribution of the corticomotoneuronal pathway to central fatigue.

Neural drive originating in higher brain areas reaches exercising limb muscles through the corticospinal-motoneuronal pathway, which links the motor cortex and spinal motoneurones. The properties of this pathway have frequently been observed to change during fatiguing exercise in ways that could influence the development of central fatigue (i.e. the progressive reduction in voluntary muscle activation). However, based on differences in motor cortical and motoneuronal excitability between exercise modalities (e.g. single-joint vs. locomotor exercise), there is no characteristic response that al…

The interaction between metaplastic neuromodulation and fatigue in multiple sclerosis.

BACKGROUND AND OBJECTIVE: Neuromuscular fatigue contributes to decrements in quality of life in Multiple Sclerosis (MS), yet available treatments demonstrate limited efficacy. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique which presents promise in managing fatigue, possibly related to its capacity to modulate corticospinal excitability. There is evidence for capitalising on metaplasticity using tDCS for improving outcomes. However, this remains to be explored with fatigue in people with MS (pwMS). We investigated cathodal tDCS (ctDCS) priming on a…
