Arthrogenic muscle inhibition manifests in thigh musculature motor unit characteristics after anterior cruciate ligament injury

ND Schilaty, AL McPherson, T Nagai… - European Journal of …, 2023 - Taylor & Francis

(AMI) that prevents complete activation of muscles. Reduced motor unit (MU) output is a …

Lower motor unit discharge rates in gastrocnemius lateralis, but not in gastrocnemius medialis or soleus, in runners with Achilles tendinopathy: a pilot study

GL Fernandes, LBR Orssatto, RL Sakugawa… - European Journal of …, 2023 - Springer

Identification of the laterality of motor unit behavior in female patients with parkinson's disease using high‐density surface electromyography

Y Nishikawa, K Watanabe, A Holobar… - European Journal of …, 2021 - Wiley Online Library
Patients with Parkinson's disease (PD) have greater laterality of muscle contraction

Synaptic inputs to motor neurons underlying muscle co-activation for functionally different tasks have different spectral characteristics.

D Borzelli, TMM Vieira, A Botter… - Journal of …, 2024 - journals.physiology.org
The CNS may produce the same endpoint trajectory or torque profile with different muscle
activation patterns. What differentiates these patterns is the presence of co-contraction …

Inter-person differences in isometric coactivations of triceps surae and tibialis anterior decrease in young, but not in older adults after 14 days of bed rest
