Spinal posture is the position of the spine in the human body. It is debated what the optimal spinal posture is, [ 1 ] and whether poor spinal posture causes lower back pain . [ 2 ] Good spinal posture may help develop balance, strength and flexibility .
The posture is also used on some types of specialized workbenches (such as a shaving horse). By definition, an essential feature is having one leg on each side of whatever is being straddled. The related sidesaddle position allows riding without straddling, but is somewhat less secure against accidental dismounting or falling.
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. [1] [2] It helps to maintain posture and declines during REM sleep. [3]
These mechanosensation circuits are important for flexibly maintaining posture and balance, especially during locomotion. For example, consider the stretch reflex , in which stretch across a muscle is detected by a sensory receptor (e.g., muscle spindle , chordotonal neurons ), which activates a motor neuron to induce muscle contraction and ...
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
To be effective while stretching, force applied to the body must be held just beyond a feeling of pain and needs to be held for at least ten seconds. Increasing the range of motion creates good posture and develops proficient performance in everyday activities increasing the length of life and overall health of the individual. [6]
Rounded shoulder posture (RSP), also known as “mom posture”, [1] is a common postural problem in which the resting position of the shoulders leans forward from the body’s ideal alignment. [1] Patients usually feel slouched and hunched, [ 2 ] with the situation deteriorating if left untreated.
Static posture, or static loading, is when a person holds a consistent posture during the entirety of the time it takes to perform a task, which does not allow the body to relax. It is a problem because it can lead to muscle pain, fatigue, and joint issues, and increases the risk for musculoskeletal injuries.
