“…The ICLabel tool (v1.3) in EEGLAB was then used as a basis for initial automatic classification of ICs (Pion-Tonachini et al 2019 ). Only ICs labelled as functional brain components with > 75% probability (Sherman et al 2023 ) were retained and included in the trial averaging, following further verification by means of visual inspection of components’ ERP waveforms, power spectra and scalp topography. Mean probability of brain classification for each participant’s retained IC was 95.6 ± 3.2% for Protocol I trials and 93.9 ± 3.2% for Protocol II trials.…”

Musculoskeletal trauma often leads to lasting psychological impacts stemming from concerns of future injuries. Often referred to as kinesiophobia or re-injury anxiety, such concerns have been shown to hinder return to physical activity and are believed to increase the risk for secondary injuries. Screening for re-injury anxiety is currently restricted to subjective questionnaires, which are prone to self-report bias. We introduce a novel approach to objectively identify electrocortical activity associated with the threat of destabilising perturbations. We aimed to explore its feasibility among non-injured persons, with potential future implementation for screening of re-injury anxiety. Twenty-three participants stood blindfolded on a translational balance perturbation platform. Consecutive auditory stimuli were provided as low (neutral stimulus [CS–]) or high (conditioned stimulus [CS+]) tones. For the main experimental protocol (Protocol I), half of the high tones were followed by a perturbation in one of eight unpredictable directions. A separate validation protocol (Protocol II) requiring voluntary squatting without perturbations was performed with 12 participants. Event-related potentials (ERP) were computed from electroencephalography recordings and significant time-domain components were detected using an interval-wise testing procedure. High-amplitude early contingent negative variation (CNV) waves were significantly greater for CS+ compared with CS– trials in all channels for Protocol I (> 521-800ms), most prominently over frontal and central midline locations (P ≤ 0.001). For Protocol II, shorter frontal ERP components were observed (541-609ms). Our test paradigm revealed electrocortical activation possibly associated with movement-related fear. Exploring the discriminative validity of the paradigm among individuals with and without self-reported re-injury anxiety is warranted.

“…Studies indicate that following ACL tear, decreased joint stability could lead to imbalances in surrounding neuro-muscular function. Weakened muscle strength and control result in abnormal joint movement [ 141 ], imposing additional stress on joint structures and soft tissues, thereby accelerating the progression of cartilage injury. Sustained ligament laxity and impaired muscle function-induced changes in neuro-muscular feedback may contribute to progressive degradation of intra-articular structures [ 142 , 143 ].…”
