Determining Subject-specific Pcsas for Muscles of the Forearm
نویسندگان
چکیده
Physiological cross-sectional area (PCSA) is a very important parameter for modeling muscle force. Most studies utilize cadaveric data when doing so, however, it is not known how appropriate this is for forearm muscles. In this study, the volumes of four forearm muscles were determined using 3D parametrized (finite element) models created with the data derived from Magnetic Resonance Imaging (MRI). These subject-specific muscle volumes were used to calculate the PCSAs of the muscles, and the results are presented.

Muscle geometry affects accuracy of forearm volume determination by magnetic resonance imaging (MRI).
Upper extremity musculoskeletal modeling is becoming increasingly sophisticated, creating a growing need for subject-specific muscle size parameters. One method for determining subject-specific muscle volume is magnetic resonance imaging (MRI). The purpose of this study was to determine the validity of MRI-derived muscle volumes in the human forearm across a variety of muscle sizes and shapes. ...

متن کاملModeling masticatory muscle force in finite element analysis: sensitivity analysis using principal coordinates analysis.
Our work on a finite element model of the skull of Macaca aims to investigate the functional significance of specific features of primate skulls and to determine to which of the input variables (elastic properties, muscle forces) the model behavior is most sensitive. Estimates of muscle forces acting on the model are derived from estimates of physiological cross-sectional areas (PCSAs) of the j...

The vertebrate musculoskeletal system is composed of skeletal levers powered by muscles. Effective mechanical advantage (EMA) and muscle properties influence organismal performance at various tasks. Anatomical mechanical advantage (AMA) is a proxy for EMA that facilitates the study of preserved specimens when many muscles or many species are of interest. AMA is the quotient of in-lever to out-l...
