?Product advantages? Using bionic design, it looks like a full human leg. The power output group of the walking aid is used to capture the gravitational potential energy and the kinetic energy of people walking, and by redistributing their own energy, the energy is finally released to assist the legs to lift and swing naturally. Please note that the Bionic Physical Walking Aid is intended to be used only as a walking aid and is designed to help elderly rehabilitating patients walk more easily and confidently. The length of the support rod is arbitrarily scalable, suitable for people of different heights Crawler type fixed waist belt, waist size can be adjusted freely ?Product parameters? Name: walking aid Size: S (waist circumference below 950mm), M (waist circumference above 950mm) Color: blue, black Weight: 0.75kg (S single leg) 1.23kg (M double leg)?Applicable People?One-sided paralysis caused by disease, weak legs and feet, the elderly need to walk for a long time, and it is inconvenient to walk due to accidents. It's lightweight to carry, yet sturdy enough for them to take out for a relaxing walk. ?Multifunctional?Ideal for physical and occupational therapists and those recovering from injury or surgery, can stretch the legs and easily maneuver onto a bed, sofa or wheelchair, and easily enter the vehicle. ?Designed for Stairs?Make going up and down stairs easy and safe, and less painful for people with knee and hip pain, speeding up the user's walking recovery rate. Help the elderly and patients walk, help patients resume training, sit down and rest. ?Natural Energy Storage Device?The intensity is adjustable. Twist clockwise for increased intensity. Get energy naturally without recharging. And the height of the legs is adjustable, suitable for people whose waist circumference is less than 95cm 37.4in. ?Bionic Design?Wear it on the weak side of the body when using it, and make up for the lack of muscle strength by conforming to the rhythm of the human body, and complete efficient and harmonious auxiliary movements with the help of natural gravity.
