myoelektromos

Myoelektromos is a term used in some languages to describe phenomena, devices, or methods that rely on the electrical activity of muscles. It can refer to both diagnostic techniques that measure muscle electrical signals and to technologies that use those signals to control equipment, such as prosthetics or assistive devices. The scope includes electromyography and the broader field of myoelectric applications.

In medical diagnostics, electromyography (EMG) involves recording the electrical activity produced by skeletal muscles. This can be done with surface electrodes placed on the skin or with needle electrodes inserted into the muscle. EMG is used, often alongside nerve conduction studies, to evaluate neuromuscular disorders, differentiate muscle from nerve problems, and assess disease progression or recovery. Normal and abnormal patterns of motor unit action potentials, recruitment, and spontaneous activity provide information about muscle health and nerve function.

In rehabilitation and assistive technology, myoelectric signals are harnessed to control devices. Myoelectric prostheses, for example, use electrical signals from residual muscles to drive movements of a robotic hand or arm. Functional electrical stimulation systems may also respond to EMG signals to assist movement or provide therapy. These applications rely on signal processing techniques to extract meaningful features from EMG data, such as amplitude, timing, and frequency components.

Overall, myoelektromos covers a range of practices and technologies centered on the electrical properties of muscle activity, including clinical measurement, diagnosis, and the development of muscle-driven interfaces.
