Gutter crutches, also known as platform crutches, are designed with a wide, flat surface on the top of the crutch that allows the user to place their arm through the crutch rather than gripping it with their hand. These crutches are often used by people with limited hand function or those who have had hand surgery, as they do not require gripping. The arm rests at 45 degrees.
Lofstrand crutches, also known as elbow crutches or Canadian crutches, are similar to standard underarm crutches, but they have a horizontal bar that allows the user to rest their elbow on the crutch rather than gripping it with their hand. These crutches are often used by people with limited hand function or those who have had hand surgery, as they do not require gripping. The arm rests at 90 degrees
