Probabilistic Multi-shape Segmentation of Knee Extensor and Flexor Muscles
Patients with chronic obstructive pulmonary disease (COPD) often exhibit skeletal muscle weakness in lower limbs. Analysis of the shapes and sizes of these muscles can lead to more effective therapy. Unfortunately, segmenting these muscles from one another is a challenging task due to a lack of image information in many areas. We present a fully automatic segmentation method that overcomes the ...
متن کاملMeasurement of fatigue in knee flexor and extensor muscles.
In order to examine fatigue of the knee flexor and extensor muscles and to investigate the characteristics of muscular fatigue in different sports, a Cybex machine was used to measure muscle fatigue and recovery during isokinetic knee flexion and extension. Eighteen baseball players, 12 soccer players and 13 marathon runners were studied. Each subject was tested in the sitting position and made...
متن کاملStrength characterization of knee flexor and extensor muscles in Prader-Willi and obese patients
BACKGROUND despite evidence of an obesity-related disability, there is a lack of objective muscle functional data in overweight subjects. Only few studies provide instrumental strength measurements in non-syndromal obesity, whereas no data about Prader-Willi syndrome (PWS) are reported. The aim of our study was to characterize the lower limb muscle function of patients affected by PWS as compar...
متن کاملSimulation of Motion Trajectory for Rehabilitation of Finger Flexor Tendons and Extensor Digitorum Tendons
Injury to finger flexor tendons or extensor digitorum tendons necessitates operations and rehabilitation to regain normal function. In this study, a system was designed to simulate the rehabilitation motions for injured finger flexor and extensor digitorum tendons, such as making a fist and extending the fingers. The dynamic system (DS) is based on a 16-segment hand model and was designed using...
متن کاملArchitectural Properties and Specific Tension of Human Knee Extensor and Flexor Muscles Based on Magnetic Resonance Imaging
The physiological cross-sectional area (PCSA) of knee extensors (KE) and flexors (KF) was determined using magnetic resonance imaging (MRI) in humans. Twenty two healthy male volunteers were assigned to the subjects and MRI was taken to obtained 41•`52 consecutive axial images (slice thickness ;10 mm, interslice gap ; 0 mm) from right-leg thigh. From these images, anatomical cross-sectional are...
