Abstract The purpose of this study was to measure the tension in the flexor digitorum profundus (FDP) tendon in zone II and the digit angle during joint manipulations that replicate rehabilitation protocols. Eight FDP tendons from eight human cadavers were used in this study. The dynamic tension in zone II of the tendon and metacarpophalangeal (MCP) joint angle were measured in various wrist an...

  Background: The aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   Methods : A total of 14 healthy females participated in this pre-experimental study. The subjects performed maximal eccentric quadriceps contractions at ...

In this study, an optimization-based approach for simulating the lifting motion of a three dimensional digital human model is presented. Lifting motion is generated by minimizing a performance measure subjected to basic physical and kinematical constraints. Two performance measures are investigated: one is the dynamic effort; the other is the compression and shear forces on the lumbar joint. Th...

1 This study presented a model-based image-matching (MBIM) motion analysis 2 technique for ankle joint kinematic measurement. Five cadaveric below-hip 3 specimens were manipulated through a full range of ankle joint motions in bare-foot 4 and shoed conditions. The ankle motions were analyzed by bone-pin marker-based 5 motion analysis and MBIM motion analysis techniques respectively. The root me...

The paper tackles the problem of real-time image motion tracking as a baseline function for visual motion estimation. Motion tracking is performed using the principles of 2D area correlation and joint transform correlation. To cope with real-time requirements a compact embedded optical Joint Transform Correlator design is presented, which allows using image motion tracking in mobile application...

BACKGROUND The sacroiliac joint is a widely described source of low back pain. Therapeutic approaches to relieve pain include the application of pelvic belts. However, the effects of pelvic belts on sacroiliac joint ligaments as potential pain generators are mostly unknown. OBJECTIVES The aim of our study was to analyze the influence of pelvic belts on ligament load by means of a computer mod...

This paper presents an interface for creating whole body motions of human and animal characters without reference motion Its basic function is to enable an imators to generate a natural motion by dragging a link to an arbitrary position with any number of links pinned in the global frame as well as other constraints such as desired joint angles and joint motion ranges Each constraint can be swi...

We present a motion exemplar approach for tracking human figures in monocular videos. A motion correlation technique is employed to measure the motion similarity at various space-time locations between the input video and stored video templates. These observations are used to predict the conditional state distributions of exemplars and joint positions. An efficient template hierarchy is generat...

A redundant robot has more degrees of freedom than what is needed to uniquely position the robot end-effector. In a usual robotic task, only the end-effector position tr'ajectory is specified. The joint position trajectory is unknown, and it must be selected from a self-motion manifold for a specified end-effector. In many situations the robot dynamic parameters such as link mass, inertia and j...
