Izomtónusra

Izomtónusra refers to the state of partial contraction of muscles at rest. It is a constant, low-level tension that allows muscles to be ready for action. This inherent tone is crucial for maintaining posture, balance, and stability. Even when you are not actively moving, your muscles are not completely relaxed; they maintain a certain level of firmness.

The nervous system plays a key role in regulating izomtónusra. It continuously sends signals to the muscles, even in the absence of voluntary commands, to keep them in this state of readiness. This involuntary activity ensures that your body can react quickly to changes in your environment or to unexpected movements.

Variations in izomtónusra can indicate underlying neurological or muscular conditions. For example, increased muscle tone, known as hypertonia, can make muscles stiff and resistant to stretching, often seen in conditions like spasticity or rigidity. Conversely, decreased muscle tone, or hypotonia, results in muscles that are floppy and weak. Observing and assessing muscle tone is an important part of neurological examinations.
