Muscle Stimulation Frequency01:22

Muscle Stimulation Frequency

4.6K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Motor Unit Stimulation01:20

Motor Unit Stimulation

4.6K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Vibrating Concrete01:19

Vibrating Concrete

1.5K
Mechanical vibrators are instrumental in compacting newly poured concrete within formwork and around reinforcements. This process is essential to eliminate trapped air pockets and establish a dense concrete mass. One widely used method is vibrating by internal vibrators, often referred to as a poker vibrator or immersion vibrator. It is rapidly inserted through the full depth of the freshly laid concrete and slightly extends into the layer below it (which remains in a plastic state). Consistent...

Electroconvulsive Therapy01:30

Electroconvulsive Therapy

2.5K
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Electrodes: Overview

2.2K
 Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...

Electro-mechanical Systems

1.2K
Electromechanical systems are intricate configurations that effectively combine electrical and mechanical elements to achieve a desired outcome. Central to many of these systems is the DC motor, a device that converts electrical energy into mechanical motion, enabling various applications ranging from simple fans to complex robotic mechanisms.
A key component of the DC motor is the armature, a rotating circuit positioned within a magnetic field. As an electric current passes through the...

Summary
This summary is machine-generated.

A new hybrid system using a floating mass transducer (FMT) and cochlear implant (CI) electrode for electric acoustic stimulation (EAS) shows promise for intracochlear fluid stimulation. Further development is needed for reliable FMT integration with CI electrodes.

Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Audiology

Background:

  • Electric acoustic stimulation (EAS) combines cochlear implant (CI) technology for high frequencies with acoustic amplification for low-mid frequencies.
  • Increasing numbers of patients with residual hearing are candidates for EAS due to advances in hearing preservation surgery.
  • Floating mass transducers (FMTs) from active middle-ear implants show potential for acoustic stimulation in EAS.

Purpose of the Study:

  • To evaluate the in situ vibration performance of a novel hybrid system for intracochlear fluid stimulation.
  • To compare the vibration performance of a floating mass transducer (FMT) coupled to a cochlear implant (CI) electrode (Vibro-EAS) against standard coupling.

Main Methods:

  • Seven fresh human temporal bones were used for the study.
  • Stapes amplitude responses were measured using laser Doppler vibrometry.
  • FMT fixation to the incus (standard) was compared with FMT fixation to a CI electrode via the round window (Vibro-EAS).

Main Results:

  • The Vibro-EAS system produced stapes amplitude responses comparable to 84 dB SPL acoustic stimulation at 0.316 Vrms.
  • However, Vibro-EAS responses were 30-42 dB lower than standard coupling (VSB) up to 4 kHz.
  • This suggests potential for intracochlear fluid stimulation but with reduced amplitude compared to conventional methods.

Conclusions:

  • Intracochlear combined electrical and mechanical stimulation is a potentially viable technique for EAS.
  • A robust method for attaching or integrating the FMT to the cochlear electrode array requires further development.
  • This hybrid approach may offer new therapeutic avenues for hearing restoration.
