Abstract To study the analysis and optimization of motion reliability multifunctional nursing bed mechanism, ADAMS software platform was chosen to simulate parametric modeling with consideration dimensional clearance errors. Taking back-raising mechanism as an example, we verify accuracy model by comparing experimental data. Based on effect error, a response surface motor end hinge clearance, p...

Antibodies that block Sonic Hedgehog (SHH) signaling have been used to show that SHH activity is required for the induction of floor plate differentiation by the notochord and independently for the induction of motor neurons by both the notochord and midline neural cells. Motor neuron generation depends on two critical periods of SHH signaling: an early period during which naive neural plate ce...

Electromyography (EMG) is a technique that gives information about the neuromuscular pattern and function which commonly-used in practice of neurology. With this method, signals obtained from muscle cells using an amplificatore are enhanced to amount enough study on. The potentials monitored called Motor Unit Action Potentials (MUAPs). In study, findings gathered by simulation dipole model for ...

BACKGROUND CONTEXT Vertebral end plate support is necessary for successful lumbar total disc replacement (TDR) surgery. Failure to achieve anterior column support as a result of lumbar TDR device undersizing could lead to implant subsidence and fracture. PURPOSE The purpose of the study was to examine the compressive biomechanical behavior of the vertebral end plate with varying sizes of disc...
