Coordination is the basic motor element of MTT

3,423

Coordination is the basic element of every movement of the human body. It is responsible for the process of learning, control and adaptation in motion. It enables a motor behavior to be performed reasonably and effectively in different situations and changing environments.

Coordination is to achieve joint stability, a certain posture and dynamic movement in the process of control and the formation of afferent and efferent nerve, muscle coordination interaction. Human coordination ability is composed of various factors, which can have different evaluation and evaluation criteria in different treatment and exercise processes. Within this framework, different coordination factors can be improved more or less selectively through a series of exercises.

Coordinate the components

Balance ability: 

Balance ability refers to the ability of the body to maintain balance or re-establish balance on a certain support surface in order to resist the action of gravity. The ability to balance plays a vital role in preventing and reducing the occurrence of falls, and it is of high value in the rehabilitation of old age.

Spatial orientation ability: Spatial orientation ability is the ability to enable people to do directional movement in a free space with a purpose. This ability enables people’s movements to remain directional in space for a certain amount of time. In the poor light or dark environment, the elderly fall coefficient is very high, which requires the middle-aged and elderly to have a good spatial direction ability. The ability of spatial orientation has great demands on the subjective visual, auditory and spatial kinesthetic systems of human body.

Responsiveness: Responsiveness refers to the organism’s ability to respond quickly, purposefully, and appropriately to internal and external stimuli.

Discriminating ability: Discriminating ability refers to the ability of the body to ensure the safe, accurate and efficient completion of the movement process when it involves the surrounding environment and the relationship between various body segments. It also includes the correct quantification of force and speed during movement and the correct estimation of spatial position.

Coupling ability: This ability refers to the ability of individual movements or movements in one segment of the body to be organically integrated with the movement of the whole body.

Rhythmic ability: 

The ability of the body to perform movements according to the corresponding rhythm is called rhythmic ability. This ability is important not only for synchronous, but also for non-synchronous forms of motion.

Three levels of coordination training 

Level A: 

Joint stability (activation of local muscle groups, deep sensory/proprioceptive training), local stabilization muscle dysfunction is the main cause of poor joint stability. The activation of locally stable muscles is mainly accomplished by isolated training of single-joint muscles. Quadriceps muscle function test: lower limb extension raised about 30°, can not keep the knee joint completely straight, the loss of degree is 5° (finally bend the knee more than 5° can not be completely straight), indicating that the quadriceps significantly inhibited. Deep sense is also called proprioception, that is, joint position sense and motion sense are also decisive factors in joint stability control. Joint Angle reset is used to test (figure below). Generally, an error value greater than 5° indicates an injury or impairment that needs to be recovered through specialized training.

Level B: 

Feedback control (posture) Static stability: The body’s static balance ability refers to the body’s ability to maintain a stable state in a certain posture (standing on one foot with eyes open/closed).

Dynamic stability: Human dynamic balance ability refers to the ability to adjust and control the body’s center of gravity and posture during exercise (SEBT star balance test).

Level C: 

Feedforward control, rapid and targeted movement dynamic and stable maintenance, including muscle preparation activities, reactive activities. In take-off and landing activities, the target muscle mobilization rate and activation sequence before landing reflect the pre-feedback mechanism of neuromuscular control, and the target muscle mobilization rate after landing reflects the feedback mechanism of neuromuscular control (LESS landing test, one-foot jump test).
