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

Architectural Ultrasound Pennation Angle Measurement of Lumbar Multifidus Muscles: A Reliability Study [PDF]
Journal of Clinical Medicine, 2022 The pennation angle has been shown to be a relevant parameter of muscle architecture. This parameter has not previously been measured in the lumbar multifidus musculature, and it is for this reason that it has been considered of great interest to establish an assessment protocol to generate new lines of research in the future.

Dynamic measurement of pennation angle of gastrocnemius muscles during contractions based on ultrasound imaging [PDF]
BioMedical Engineering OnLine, 2012 Background Muscle fascicle pennation angle (PA) is an important parameter related to musculoskeletal functions, and ultrasound imaging has been widely used for measuring PA, but manually and frame by frame in most cases.

Changes in muscular pennation angle after crenotherapy [PDF]
Muscle, Ligaments and Tendons Journal, 2013 Muscular architecture involves the organization of fibres in the muscle and is one of the most important factors of muscular function. Studies have demonstrated an association with muscular architecture and contraction, with an increase of the pennation angle in muscles.

A Proactive Technique for Pennation Angle Estimation of Skeletal Muscles Using Ultrasound Imaging
Frontiers in Biomedical TechnologiesPurpose: The concrete construction of the musculoskeletal modeling is efficiently performed using information obtained from patients rather than collected from cadavers. In this study, we have endeavored to propose an automated technique that calculates

Human gastrocnemius medialis Pennation Angle as a Function of Age: From Newborn to the Elderly.
Journal of Physiological Anthropology and Applied Human Science, 2001 The aim of the present study was to quantify changes in human skeletal muscle pennation angle (F theta) values during growth and adult life. The human gastrocnemius medialis muscle of 162 subjects (96 males and 66 females) in the age range 0-70 years was scanned with ultrasonography. The subjects were laying prone, at rest, with the ankle maintained at

A clustering-based method for estimating pennation angle from B-mode ultrasound images
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 ...

Change in Gastrocnemius Pennation Angle According to Ankle Dorsiflexion among University Students
Journal of the Korea Academia-Industrial Cooperation Society, 2015 본 연구의 목적은 발목관절의 발등굽힘 각도를 $0^{\circ}$ , $10^{\circ}$ , $20^{\circ}$ 로 위치하게 한 후 각 각도에서 장딴지근의 깃각 변화에 미치는 영향을 비교하여 효율적인 장딴지근 신장 각도를 제시하는 것이다. 건강한 성인 남녀 25명을 그 대상으로 하여 발목관절 발등굽힘 각도 $0^{\circ}$ , $10^{\circ}$ , $20^{\circ}$ 에서 초음파 기기를 이용하여 내측 장딴지근의 깃각을 측정하였다. 각도별 장딴지근의 깃각 변화를 알아보기 위해 반복측정분산분석을 성별에 따른 각도별 차이를 알아보기 위해 독립 t 검정을 실시하였다.
