Conventional crutches use your hands and arms to support your weight, while the iWalk medical crutch uses the uninjured parts of your leg to support your weight when you stand or walk. Conventional crutches cause discomfort by putting unnatural pressure on your hands and underarms. Conventional crutches cause chafing, can rub the skin under your arms raw, cause irreparable nerve damage, and easily fatigue your hands and arms. Basically, conventional crutches make the simple act of getting around a strenuous chore. iWALK 2.0 can end all of this unnecessary pain and discomfort. Instead of bearing the weight in your arms, your weight is transferred to your shin. Note - while it may appear that the weight is supported by the knee while using the iWALK 2.0 Hands-Free Crutch, this is not the case. Your knee doesn't bear any weight when using iWALK 2.0. The iWALK 2.0 functions under a similar principle as a knee scooter, where you kneel on a platform to support your weight. Unlike other crutch alternatives, the iWALK 2.0 provides this comfort in addition to unsurpassed mobility on many types of terrain, making it the obvious choice in comparison to other crutch alternatives.
