A computational model to investigate the effect of pennation angle on surface electromyogram of Tibialis Anterior. [PDF]
PLoS ONE, 2017 This study has described and experimentally validated the differential electrodes surface electromyography (sEMG) model for tibialis anterior muscles during isometric contraction. This model has investigated the effect of pennation angle on the simulated

A clustering-based method for estimating pennation angle from B-mode ultrasound images [PDF]
Wearable Technologies, 2023 B-mode ultrasound (US) is often used to noninvasively measure skeletal muscle architecture, which contains human intent information. Extracted features from B-mode images can help improve closed-loop human–robotic interaction control when using ...

The influence of muscle pennation angle and cross-sectional area on contact forces in the ankle joint [PDF]
J Strain Anal Eng Des, 2016 Data about a muscle’s fibre pennation angle and physiological cross-sectional area are used in musculoskeletal modelling to estimate muscle forces, which are used to calculate joint contact forces.

The Effect of Self-Myofascial Release on the Pennation Angle of the Vastus Medialis Oblique and the Vastus Lateralis in Athletic Male Individuals: An Ultrasound Investigation [PDF]
International Journal of Sports Physical Therapy, 2022 # Background Maintenance of patellar stability requires a balance between the vastus medialis oblique (VMO) and the vastus lateralis (VL). The imbalance between these muscles is thought to be implicated in the etiology of patellofemoral pain (PFP ...

The hidden architecture of back pain: ultrasound-based lumbar multifidus pennation angle analysis - a cross-sectional pilot study [PDF]
BMC Musculoskeletal DisordersBackground Chronic low back pain (CLBP) is associated with structural and functional alterations in the lumbar-multifidus (LM) muscle, a key-stabilizer of the spine.

Impact of contraction intensity and ankle joint angle on calf muscle fascicle length and pennation angle during isometric and dynamic contractions [PDF]
Scientific ReportsDuring muscle contraction, not only are the fascicles shortening but also the pennation angle changes, which leads to a faster contraction of the muscle than of its fascicles. This phenomenon is called muscle gearing, and it has a direct influence on the

Effect of standard- versus high-protein enteral feeding on rectus femoris muscle mass in mechanically ventilated traumatic brain injury patients: a prospective randomized study in Egypt and the United States [PDF]
Acute and Critical CareBackground Critically ill patients with muscle wasting experience prolonged intensive care unit (ICU) stays, delayed weaning, and higher mortality. Trauma-induced stress disrupts protein metabolism, leading to immunosuppression and muscle loss.
