The present study addressed the effect of articular conformity of the shoulder joint on the stability of inter-joint coordination during circular drawing movements. Twelve right-handed participants performed clockwise and counter-clockwise circular drawing movements at nine locations in the mid-sagittal plane. The task was paced acoustically at 1.0, 1.5 and 2.0 Hz and performed without visual c...

Multiple target tracking (MTT) is taken into account as one of the most important topics in tracking targets with radars. In this paper, the MTT problem is used for estimating the position of multiple targets when a 2-D radar is employed to gather measurements. To do so, the Joint Probabilistic Data Association Filter (JPDAF) approach is applied to tracking the position of multiple targets. To ...

The chordotonal organ at the femorotibial joint of a locust hind leg monitors extension and flexion movements of the tibia. During evoked or imposed movements of this joint the central terminals of afferent neurons from the chordotonal organ receive depolarizing, inhibitory synaptic inputs. The afferent spikes are therefore superimposed on these depolarizing IPSPs, which are generated indirectl...

Gait analysis has historically been implemented in laboratory settings only with expensive instruments; yet, recently, efforts to develop and integrate wearable sensors into clinical applications have made. A limited number of previous studies conducted validate inertial measurement units (IMUs) for measuring ankle joint kinematics, especially small movement ranges. Therefore, the purpose this ...

Inertial measurement units (IMUs) increasingly function as a basic component of wearable sensor network (WSN). The IMU-based joint angle estimation (JAE) is typical usage IMUs for WSN, with extensive applications. However, the issue that move respect to their original placement during JAE still research gap and limits robustness deploying technique in real-world application scenarios. In this s...

BACKGROUND How the central nervous system (CNS) organizes the joint dynamics for multi-joint movement is a complex problem, because of the passive interaction among segmental movements. Previous studies have demonstrated that the CNS predictively compensates for interaction torque (INT) which is arising from the movement of the adjacent joints. However, most of these studies have mainly examine...
