Description

Center of gravity movement improvement device {Balance Meter}

The present invention relates to a center of gravity exercise improvement device (balance meter), and more particularly, as the elderly get older, the center of gravity shakes, the balance of the body collapses, and behavioral problems occur due to uncomfortable behavior. It relates to a center of gravity movement improvement device for a body balance test system by manufacturing posture and balance maintenance exercise equipment as a smart healthcare device.

Korea's aging rate is the highest in the world, and since entering an aging society in 2000 (7% or more of the population aged 65 or older in the total population), it has become an aged society in 2017 (more than 14% of the total population, as of 2013 6.14 million, corresponding to 12.2% of the total population), and is scheduled to enter a super-aged society in 2026, and the aging problem in Korea is becoming more serious. As society ages, various problems arise. We focus on the health problems of the elderly and seek solutions.

In the era of COVID-19 and the aging of society, the demand for medical services for the elderly increases, resulting in a rapid increase in medical costs and a deepening shortage of professional healthcare personnel. This situation can cause the problem of economic poverty in terms of the elderly, and can cause a problem in that the financial burden of supporting the elderly population increases in terms of the young and old. In addition, there is a risk that additional problems such as a lack of professional healthcare personnel and an increase in social welfare expenses may be caused by an increase in the number of elderly people with deteriorating health. Since this arithmetic increase in the elderly population cannot be solved by simple budget increase or by the efforts of young people, a solution must be sought through the development of new business fields.

Worldwide, the smart healthcare industry has entered a market growth period with smartphones and IoT-based wearable devices, and various types of smart healthcare products and services that combine biotechnology and information and communication technology are being released. Companies with various ideas, from global ICT companies to start-ups, as well as medical device companies, are accelerating their entry into the market. The global market size of smart healthcare products is expected to show continuous growth.

According to the Korea Health Industry Development Institute, the global smart healthcare market, which stood at $21 billion in 2014, is expected to grow by about 4.8 times to reach $101.5 billion in 2020.

As the elderly get older, the center of gravity shakes, the balance of the body collapses, and behavior problems occur due to uncomfortable movements. Coordination of timing and cooperation and control of muscle tone make coordinated movements impossible.

Balance is the ability to maintain the center of gravity on one's base of support within a given environment and is a series of complex processes influenced by various factors. In other words, it is a complex motor skill resulting from the interaction of many sensory-motor-perceptual responses rather than the product of a single system, righting, or equilibrium reflex.

The cerebellum is responsible for balance control. The cerebellum receives information from the cerebral cortex, the basal ganglia, the spinocerebellar tract, the cerebellar nuclei, and the vestibular pathway. It transmits information to cranial nerves, vestibular pathways, etc., controls the appropriate timing and cooperation of muscles during body movements, and plays a role in helping harmonious movements through the control of muscle tension.

The multifactor function evaluation method is an evaluation method developed with an emphasis on balance function performance by combining many factors to be considered in maintaining posture and balance. Dots were originally made for the elderly, but are now being used for brain disease patients.

The Fugl-Meyer motor evaluation is an evaluation method designed to evaluate the recovery of motor function in stroke patients, and it can evaluate 7 items (0 to 14 points) in the Balance section of Fugl-Meyer Motor Assessment (FMA-B). . In addition, among the eight items of the Motor Assessment Scale (MAS), which facilitates the observation of motor function evaluation over time in stroke patients, the item (sit-MAS) that evaluates the ability to balance in a sitting position can be measured. there is.

The body balance safety test measures the pressure change in each part of the foot using the simultaneous measurement of four precise sensors (load cells) and the standard Stabilometry measurement protocol to find the center of press (COP) of the body and the center of body pressure. By analyzing the length, area, speed, and center of the trajectory of the movement, the safety of the core muscles and the ability to control the front/back/left/right and agility are evaluated.

The Romberg test collects changes in the body's center of pressure for 30 seconds each with eyes open and closed, then analyzes the length, area, and speed of the center of pressure trajectory to quantitatively evaluate the body's equilibrium ability, and somatosensory and vestibular function are evaluated simultaneously.

When the body balances well with the eyes open, but the body loses balance when the eyes are closed, the Rumberg aspect is evaluated, suggesting a malfunction in the proprioceptive system.

On the other hand, if there is an abnormality in the cerebellar function, postural instability is shown even when the eyes are open, and the tendency is aggravated when the eyes are closed.

The squat test collects the variation of the center of pressure of the body for 10 seconds each in the upright and squat postures (30°/60°/90°), then analyzes the length, area, and speed of the trajectory of the center of pressure. Evaluate balance ability quantitatively, and evaluate left/right balance maintenance ability of core muscles.

position balance: The stability and mobility of the human body are directly related to the ability to perform functional activities.

Balance has an important influence on the performance of all movements, and is the ability to maintain the body in a state of equilibrium, that is, the ability to maintain the center of gravity on the base of the body in a correct posture. Factors affecting balance can be largely divided into musculoskeletal factors and neurological factors. Musculoskeletal factor refers to the influence of the musculoskeletal system on postural alignment or flexibility necessary for balance, and neurological factor refers to fixation, muscle strength, and endurance so that the body can move through the process of sensory processing, integration of the central nervous system, and establishment of an exercise program. refers to any process that affects balance by regulating

Balance can be largely divided into static balance and dynamic balance. Static balance is the ability to maintain balance when maintaining a posture, and the ability to maintain a posture so that the body does not move by placing the center of gravity within the base of support. It is the ability of the body to maintain balance as it moves and to maintain a desired posture while the body is moving within the base of support.

static balance: observe/evaluate the patient's ability to maintain a fixed posture when pushed

dynamic balance: Evaluates the ability to maintain posture while shifting weight

sitting balance (evaluate 2)

(1) Measured in long sitting (2) Measured in chair sitting

standing balance: measured while standing

- If you cannot stand up, Zero or Poor

- Fair if you need a little assist

- Good or normal if you wake up on your own without the help of a therapist
