How to estimate the height of crutches:
1. When the crutches are placed in front of the feet, the angle of the elbow joint is at the height of 30°~40°.
2. The height from the ground to the wrist or the height from the ground to the femoral socket when the arm is vertical.
3. Calculation method of crutch length:
Height/2+2~3cm (the thickness of the general sole) = the length of the crutch
