Can we just forget about pennation angle?

Journal of Biomechanics, 2022
Skeletal muscle design studies, based on anatomical structure, extend back several hundred years. Accurate anatomical drawings show that many muscle fibers are oriented at an angle relative to a muscle's axis of force generation. This pennation angle has been reported in the skeletal muscle biomechanics literature, primarily in the context of trying to

Automatic Measurement of Pennation Angle from Ultrasound Images using Resnets

Ultrasonic Imaging, 2021
In this study, an automatic pennation angle measuring approach based on deep learning is proposed. Firstly, the Local Radon Transform (LRT) is used to detect the superficial and deep aponeuroses on the ultrasound image. Secondly, a reference line are introduced between the deep and superficial aponeuroses to assist the detection of the orientation of ...

Pennation angle of the soleus in patients with unilateral Achilles tendinopathy

Disability and Rehabilitation, 2008
We measured the ultrasound scans of 23 (21 males, two females) physically active subjects (mean age: 40 years; range: 20 - 58) with unilateral Achilles tendinopathy to determine the pennation angle in the soleus muscles of the affected and non-affected limb. All scans were performed by one radiologist. The pennation angle was lower on the affected side
