1, walker support points, large support area, can provide higher support force and stability. Therefore, it can better support the weight, reduce the weight of the user’s lower limbs, maintain the balance of the body, and improve the user’s ability to stand and walk, but the travel speed is slow and it is more difficult to go up and down stairs. It is suitable for those who have some support ability and stepping ability of lower limbs, but have weak muscle strength, poor balance and coordination ability. 2, many types of walkers, choose one is to choose according to the user’s own condition and needs to suit their needs; second, to pay attention to product quality, the market is a wide range of products, quality also has some differences, so do not ignore the quality of products and safety performance. When choosing products, one is to pay attention to check the quality of the product’s appearance, the surface of the product should not have burrs and sharp edges, connecting screws should have a protective cap, handle set with a tight not loose, foot pads, handles and other plastic and coloring products should not lose color in use; second is to check the performance, foot pads to have flexibility and a certain friction, especially to try the product, in normal use will not produce a strange sound, no load when the help Walkers landing to be smooth; Third, check the height and folding stool adjustment device, without the use of any tools, the positioning pins can be fully inserted into the positioning holes and fixed reliably. 3, in the use of walkers, to prevent excessive forward or backward body movement, so that the body’s center of gravity deviates from the support surface, resulting in body balance disorders. Need to master the walker height determination method, that is, the body upright, with the elbow joint flexion 30 degrees state handheld walker, so that the height of the walker and the body rotor (joint protrusion parts) to maintain a horizontal position, the height of the walker is the most appropriate height, this height can be adjusted by the walker telescopic rod. 4, the walker provides a wider and more stable support surface, but also makes it larger, to a certain extent will affect the normal gait, so it is mostly used in the early stages of rehabilitation or really need to walk with a walker, but do not rely too much. At the same time, using a walker, avoid wearing slippers and shoes with heels that are easy to loosen; pay attention to maintaining body balance when walking, glasses to the front, do not look down at their feet; lift or push the walker forward should not be too far from the walker, step when the leg is not too close to the walker; use wheeled walker walking speed is not too fast.
