Correction to: The impact of eccentric muscle contractions on peripheral nerve integrity

In the original version of this article, the second affiliation’s order were incorrectly given as Sports Medicine and Science, Luxembourg Institute of Research in Orthopedics, Luxembourg, Luxembourg but should have been Luxembourg Institute of Research in Orthopedics, Sports Medicine and Science, Luxembourg, Luxembourg In the keyword section, one of the key words “Experimentation (SYRCLE)’s Risk of Bias (RoB) tool” was inadvertently included twice. In Table 1, the word ‘paragraph’ should be deleted between population and inclusion criteria. Inclusion criteria are a subheading and should be on the bottom line, below the population. The correct Table 1 should have appeared as shown below. Overview of the selection criteria according to PICO strategy and type of studies Selection criteria according to PICO strategy and type of studies Population Inclusion criteria –Animal studies, involving healthy adult animals, considering all species, sex and weight. –Human studies, involving healthy asymptomatic adults (i.e., >18 years), considering both sexes, race, ethnicity or other demographic characteristics. Exclusion criteria – Articles that evaluated changes with age comparing the effects of eccentric contractions between young and elderly animals or subjects were excluded. Intervention – Eccentric contractions of upper or lower limb skeletal muscles. Comparison – No intervention; i.e., no other modality or a different protocols of eccentric contractions (i.e., different number of series and sets, angular velocities, multiple bouts). Outcomes Function: Sensory and motor nerve function–nerve conduction velocity. Structure and morphology (from micro to macro levels): nerve fibre diameter and myelin sheath thickness (via microscopic analysis); fascicle number (i.e., axon density) and size (i.e., diameter) by high frequency ultrasonography or magnetic resonance microscopy; nerve thickness by ultrasound (US) or magnetic resonance imaging (MRI) or microscopic analysis; nerve cross sectional area (CSA) by US or MRI or microscopic analysis; nerve volume with freehand 3D US or MRI. Physiology: intraneural blood flow measured with Doppler US (B-mode with Colour Doppler) or laser doppler flowmetry; change in molecular expressions (proteins): myelin sheath protein zero (p0); growth-associated protein 43 (GAP-43); myelin-associated glycoprotein (MAG); peripheral myelin protein 22 (PMP22); galectin-3/MAC-2; tropomyosin receptor kinase C (TrkC); neurotrophins [nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin 3 (NT-3) and neurotrophin 4/5 (NT-4/5)] (through immunohistochemistry); serum levels of neuroinflammatory mediators (or through immunohistochemistry), such as cytokines, neuropeptides, reactive oxygen species, and chemokines; alterations in signal intensity (T1 and T2 via MRI) and echo intensity (via high-resolution US). Biomechanics: nerve strain; excursion, and stiffness via US and US elastography (shear wave elastography). Type of studies Included – Randomised controlled trial and non-randomised controlled trials (quasi-experimental studies). – Published in English, peer-reviewed and available in full-text. Excluded – Reviews, case reports, editorials, protocol studies, clinical guidelines, and conference articles.
