Ankle and foot orthosis is mainly suitable for children with valgus, embargo, cerebral palsy, hemiplegia and incomplete paraplegia. The role of the orthosis is to prevent and correct deformities of the limbs, suppress tension, support, stabilize, and improve functions. Its effects are divided into production effects and use effects.
A qualified ankle and foot orthosis must have the following characteristics: effectively improve the function of the lower limbs in daily life; it will not cause too much difficulty when wearing; the user will not feel too much discomfort;
Some patients fail to achieve their due to improper use of the orthosis. Therefore, correct wearing is the key to the function of the orthosis. The following points and precautions for wearing the orthosis by several types of patients are introduced below.
How to wear: Put AFO on your feet and then into your shoes, or put AFO in your shoes and put your feet in. Pay attention to the tension of the middle bandage and make appropriate records, gradually. During the first month of wearing, new users should take off for 15 minutes every 45 minutes to allow their feet to rest properly and can massage their feet. Let your feet get used to the orthosis. After one month, you can slowly increase the time of each wear. When using it, the family should check the patient's feet daily to see if there are any blisters or abrasions on the skin. After the new AFO user removes the AFO, red marks appear on the pressure pads. These red marks can be eliminated in 20 minutes; if it cannot be eliminated for a long time, or a rash appears, the orthopedist should be notified immediately. AFO must not be worn at night without the special requirements of the orthopedic surgeon. In addition, care should be taken to maintain cleanliness and personal hygiene.
The AFO contact surface is very slippery and cannot directly contact the ground. The user must wear shoes to prevent slipping. The shoes must be medium in size and high heels and slippers cannot be worn. The shoes should be properly tightened when worn, and the height of the heel should be correctly guided by the orthopedics according to the patient's condition.
Through the above introduction, I believe that everyone has a clear understanding of how to wear an ankle and foot orthosis. In addition, please note that the AFO must be worn correctly; do not immerse the AFO in water; do not dry the AFO with hot air; follow the orthopedic arrangements and replace it at least once a year; if you encounter any problems, please notify you immediately Orthopedist.
The purpose of wearing orthotics in patients with cerebral palsy is mainly to assist standing and walking, correct deformities or consolidate the effect of correction, and affect muscle tension. Deformation of the knees, ankles, and feet is prone to occur if not worn for a long time. After giving the appropriate orthotics to wear, due to the correction of the force line, some of the joints of the child, especially the development of the foot, will experience a rapid and compensatory recovery phase. We recommend (depending on your child's development) to replace orthopedic shoes once to deal with your child's development. If improperly worn, the force application position of the orthosis will be inconsistent with the patient's intended force position, which will not be able to play its due role and may even have a counter-action.
■ Patients with low muscle tone
The purpose of wearing AFO in patients with low muscle tone is to hope to give children more support to facilitate exercise. However, wearing AFO for a long time will make some muscles lack of exercise, resulting in decreased muscle strength or muscle atrophy, but will reduce children's motor function. Therefore, when this type of child is not wearing an orthosis, he should give the child appropriate massage and muscle training.
■ Patients with high muscle tone
When a child with high muscle tone has just worn an orthosis, his heel often cannot be worn to the corresponding position of the AFO heel, and pressing on the back wall of the AFO will cause greater pressure at the heel, causing local redness and swelling. Even bruises. In some children, foot inversion and foot eversion are more serious. When wearing AFO, it will cause local entrapment and pain in the protruding parts of the lateral ankle and scaphoid bones. Therefore, when wearing, you should adopt the position of backrest, hip flexion, knee flexion, and ankle flexion to reduce tension, relieve tension, and ensure that the heel is in place. In addition, the fixing strap should not be tightened too much. If necessary, you need to remove the orthosis. , Wear a massage and rest, and gradually increase the wear time. Under normal circumstances, children with oppression will get better after adapting for a period of time. If you still cannot adapt, you should contact the production unit for a solution.
■ For children with intermittent cramps and unstable tension in the hands and feet, they often feel uncomfortable when they first wear it. According to the methods described above, it won't take long for the child to adapt.
■ Handling of lower limb orthosis when crawling: The child wearing an ankle and foot orthosis will have difficulty when crawling. That is because the orthosis hinders ankle plantar flexion. He can only use the knee to further flex or increase hip rotation. The extent of abduction comes forward. Crawling is the main method for children to explore freely while moving, so it is best to take off the orthosis during training and play.
■ Precautions when sitting for a long time: The stability of sitting on the floor wearing AFO will be poor, because children often have the tendency to sit in "W", and the orthosis will have restrictions on this. So be sure to let your child sit in a chair or take off the AFO while sitting for a long time.
■ Hemiplegia patients need ankle and foot orthosis
1) For those who are bedridden, they play a role in preventing foot drop and varus deformity. Most patients with spasticity develop from the relaxation phase, so it is necessary to prevent them in advance. Due to the long rehabilitation process, it is questionable whether the patient can adhere to good rehabilitation exercises at home. If a long period of poor gait will eventually lead to the development of joint deformities. To minimize this situation, the use of orthotics is recommended.
2) For patients who have developed deformity, the use of orthotics can promote the patient's rehabilitation and correct the deformity.
It can be seen that correct wearing of the orthosis can fully realize the design concept of orthopedics so that users of the orthosis can get the best recovery with the help of orthosis. Therefore, we must master the correct wearing and using methods. At the same time, as the patient's condition recovers, follow-up adjustments to the orthosis must be made to achieve the best correction results.
