MUSCLE TONUS Meaning and
Definition
-
Muscle tonus refers to the continuous state of slight tension or contraction present in the muscles, even when at rest. It is the natural resistance or firmness exhibited by muscles, enabling them to maintain their shape and readiness for action. Muscle tonus is regulated by the central nervous system, specifically the motor neurons, which initiate and control muscle contractions.
Healthy muscle tonus is vital for normal bodily functions and movement. It ensures stability and postural support, helping us maintain an upright position against the force of gravity. This constant low-level tension in skeletal muscles provides a basal level of strength and flexibility, allowing for efficient response to sudden movements or external forces.
Altered muscle tonus can have various implications. Hypertonus refers to increased muscle tension, making muscles feel rigid or stiff. This can result from conditions such as spasticity, where there is hyperexcitability of motor neurons due to injury or neurological disorders. Conversely, hypotonus occurs when there is a decrease in muscle tone, leading to floppy or weak muscles. Hypotonia may arise from neurological conditions or muscle disorders, affecting coordination and voluntary movements.
Assessing muscle tonus is an important component of physical examinations and clinical evaluations. Healthcare professionals use specialized techniques, such as observation, palpation, and range of motion tests, to evaluate muscle tone and identify abnormalities. Rehabilitation and therapeutic interventions often focus on restoring or modifying muscle tonus to improve functional abilities and overall well-being.

Etymology of MUSCLE TONUS
The word "muscle tonus" is derived from the Latin word "tonus", which means tension or tone. In Greek, the word "tonos" also refers to tension. When combined with the word "muscle", it specifically refers to the constant low-level contraction or slight tension present in a muscle in its resting state. Therefore, "muscle tonus" describes the baseline level of muscle contraction that allows for the maintenance of posture and joint stability.
