Postural reflex: a mechanism for maintaining balance

The postural reflex, also known as the postural reflex or static reflex, is an important mechanism for maintaining balance and constant posture in humans. This reflex plays a key role in maintaining an upright body posture and compensating for changes in external conditions, such as a shift in the center of gravity or surface unevenness.

Optimal postural stability is an essential condition for the performance of many motor tasks, including walking, standing and performing various motor acts. The postural reflex provides the necessary adjustments and adaptations in muscle activity to maintain balance and prevent falls or discomfort.

The mechanism of action of the postural reflex is based on a complex relationship between the vestibular system (responsible for the sense of balance and spatial orientation), the visual system and sensory receptors in the muscles and joints. When a change in body position or orientation occurs, these sensory systems register these changes and transmit information to the central nervous system.

The central nervous system, in turn, analyzes the received data and generates appropriate commands to activate muscles, providing the necessary correction of posture. This may include changes in muscle tension, activation of certain muscle groups, or a shift in the body's center of gravity. As a result, balance and posture stability are maintained.

The postural reflex works automatically and unconsciously, without the participation of volitional control. It demonstrates high efficiency and accuracy in maintaining balance, even under changing physical environmental conditions.

However, in some people the postural reflex may be impaired due to various reasons, such as diseases of the vestibular system, nerve or muscle damage, and aging. This can lead to problems with balance, coordination and an increased risk of falls.

Intervention by physical therapists and rehabilitation specialists may be useful in restoring and improving postural reflex function in people with such disorders. Specific exercises and techniques can help strengthen muscles, improve coordination, and restore normal response to changes in body position.

In conclusion, the postural reflex is an important mechanism for maintaining balance and constant posture in humans. It provides stability and stability of posture, adapting to changes in external conditions and maintaining balance. Understanding this reflex has significant implications for physical therapists, rehabilitation professionals, and anyone who works with people who suffer from balance or coordination problems.

The postural reflex is a group of muscle reactions in response to mechanical irritation of the fascia. Like any other behavioral reaction, the postural reaction develops under the influence of a number of factors, including the predominant influence of cortical influences. Under the influence of an afferent impulse, an impulse occurs from the fascia receptors to the motor neurons of the spinal and medulla oblongata, then to the motor neuron of the cerebellar cortex. This impulse transmits signals to the muscles involved in the reflex. In simple terms, muscle excitation occurs without an external stimulus. With the destruction of the postural reflex, signs of muscle tone disorders throughout the body become obvious, and a gait defect is observed. Fast

The postural reflex is a rather rare phenomenon and a phenomenon that has not been fully studied, because in medicine there is not yet a generally accepted approach to defining this reflex.

Most often, the term “postural reflex” or “status reflex” is used to refer to the postural reflex.
