Description

Balance ability training device and training method based on water bag

Technical Field

The invention belongs to the field of elderly people's annual balance ability training devices, and particularly relates to a balance ability training device and method based on a water bag.

Background

Along with the obvious decline of various physical functions of the old. Wherein the reduction of muscular strength, proprioception and vestibular sensation has a great influence on the loss of the balance ability of the elderly. Deterioration of the balance can lead to an increased risk of falls in the elderly, with about 53% of elderly falls being due to deterioration of the balance. The training device has the advantages that targeted training is carried out aiming at three main factors (muscle strength, proprioception and vestibular sensation) influencing the reduction of the balance ability of the old people, the improvement of the balance ability of the old people is facilitated, the falling risk is reduced, and the training device has strong practical significance.

The training equipment controls the movement of the supporting flat plate (5) at each degree of freedom by using a mechanical structure, exerts disturbance on the balanced posture of the human body through the inclination and the vibration at different angles, trains the disturbance resistance of the human body, and further improves the balance capacity. However, these training apparatuses are large, complicated in structure, and expensive, and are not suitable as general training apparatuses. In addition, the training equipment is not specially designed for the training of the balance ability of the old, and is partially applied to improving the balance ability of athletes, astronauts and teenagers, and has large movement amplitude and high strength; the other part of the rehabilitation training is applied to rehabilitation training of disabled people and functional injury diseases, and the exercise amplitude is too small and the strength is too low; are not suitable for the training of the balance ability of the old.

The spiral plate 21 in the water bladder 2 in example 1 was used. When the water pocket is complete hollow structure, rivers directly pass from the water pocket, and the both sides pressure of water pocket will be unbalanced, and the back is stepped on to old person's both feet, and the holding power that the both feet received is unbalanced, can influence old person's balance ability training because of the reason of water pocket. The spiral plate can lead the water flow to spirally advance to pass through the water sac 2, so that the pressure of each area on the same radius range of the water sac is kept close, and the both feet can be given basically the same supporting force. The spiral board 21 has the function that the supporting force received by both feet is basically the same, and the influence on the balance training of the old left and right upwards is avoided.

With respect to the spacer 20 in the water bladder 2 in embodiment 1. When there is no partition 20 in the water bladder 2, as shown in fig. 4, the front end of the water flow is a low pressure area and the rear end is a high pressure area when viewed in the flow direction, and the supporting force applied to the toe portion and the heel portion is different. The invention forms the upper and lower layers of the water bag 2 by the clapboard 20, because the water flow directions of the upper and lower layers are opposite, the high-pressure and low-pressure areas are overlapped for neutralization, the supporting force of each area of the sole is balanced, and the influence on the front-back upward balance training of the old is avoided. The spiral plate 21 and the baffle plate 20 are used for avoiding the influence on the balance ability training of the old due to the partial non-uniform pressure of the water sac.

The invention has the advantages of suitability for the training of the balance ability of the old, lower energy consumption and better training effect.
