Abstract
Background: Skeletal muscle morphology plays an essential role in determining function. Ultrasonography has been widely adopted to evaluate the morphological parameters of different muscles in both static and dynamic circumstances. In recent years, numerous algorithms, especially automated algorithms, have been developed to extract morphological parameters from musculoskeletal ultrasound images. It is now possible to analyze muscle contraction dynamics not only using traditional techniques, such as Mechanomyography (MMG) and Electromyography (EMG), but also using ultrasonography.
Conclusion: This review summarizes the important progress in these processing algorithms for different morphological parameters and concludes with recent results and forward-looking issues.
Keywords: Cross-sectional area, fascicle length, morphological parameter, muscle thickness, musculoskeletal ultrasound image, pennation angle.
