1.Applicable people: Suitable for the upper limb function is sound, the lower limb function exists moderate impairment, such as lower limb muscle strength loss, pain, after surgery and other cases can not be completely weight bearing (lower limb bone and joint injury and fracture after surgery, joint replacement, etc.); can not use the left and right foot alternate steps, such as paraplegia. The cane is mainly used for people with mild balance disorders and those who need to take safety measures when walking. 2, how to adjust the height of the axillary crutch appropriate? Generally, you should choose an axillary crutch with a telescoping pole and adjustable length, which can be adjusted appropriately according to your height. Three methods (below): A, standing position, in the armpit and the top of the axillary crutches reserved 5cm gap (about three finger height), the distance from the top of the staff to the bottom of the foot is the height of the crutches B, lying position, the measurement should be based on the above-mentioned increase of 2cm shoe height C, height minus 41CM axillary crutches height adjustment confirmation method 3, how to adjust the position of the handle to determine? Method: A. Place the crutch vertically on the outside of the little toe about 15-20cm, the elbow joint is flexed 20-30 degrees, the wrist joint is located both the position of the handle. This method is also used to determine the height of the cane (below) B. When the cane is upright, the height of the human body’s greater trochanter (the bone that can be felt on the outside of the hip joint moving back and forth when lifting the thigh) is the position of the handle. This method can also be applied to the cane (or handle) height confirmation (the following figure). Cane (or handle) height confirmation method 4.What is the correct posture for holding crutches (using double crutches as an example)? Adjust the height, stand upright and place the crutches on the outside of the front of the little toe about 15-20cm, touching the ground firmly. Place the axillary pads of the crutches against the rib cage of the chest wall on either side of the axilla. Wrist joint neutral position of both hands (both hand position and small arm in a straight line, wrist neither upturned nor pressed wrist) hold the handrail and support the body with the strength of the arms to complete the movement. Remember not to brace the crutch under the armpit to avoid damage to the soft tissues of the armpit, local blood vessels and nerves, and can affect gait. Must pay attention to: unilateral lower limb injuries need to use a single crutch, should be the healthy side (good leg side) crutches, not “which side of the leg is bad to crutches in which side, the crutches as legs”. The reason is that if you use the affected side of the crutches, in order to reduce the weight of the affected leg, you must tilt your body in order to make the crutches support more weight, and it is very easy to fall. If the affected leg can not bear weight at this time, you can only use the crutches to support the weight of the affected side to support all the weight to jump a step, which is very dangerous. This is very dangerous and is not conducive to the recovery of normal gait.
