Use of ankle foot orthosis (AFO)

■ Patients with cerebral palsy
The orthosis worn by cerebral palsy patients with abnormal posture and motor dysfunction can assist standing and walking, correct deformity or consolidate the correction effect, and affect muscle tension. If you do not wear it for a long time, you will easily deform your knees, ankles and feet. After wearing the appropriate orthosis, due to the correction of force line, some joints, especially the development of feet, will undergo a rapid compensatory recovery stage.
■ Patients with high muscle tone
When a person with high muscle tension just wears orthosis, his heel often cannot reach the corresponding position of the AFO heel, and the pressure on the AFO rear wall will produce greater pressure on the heel, causing local redness and even bruise. Therefore, when wearing, you should take the posture of back leaning, ankle bending, knee bending, hip bending, to reduce tension, relieve tension, and ensure that the heel is in place. In addition, the fixed belt should not be too tight. If necessary, you should take off the orthosis for a period of time, and then wear it after massage and rest, gradually increasing the wearing time.
■ Patients with hypotonia
The purpose of wearing AFO for patients with low muscle tone is to provide more support and facilitate exercise. However, wearing AFO for a long time will make some muscles lack exercise, resulting in muscle strength decline or muscle atrophy, and will reduce people's motor function. Therefore, when this type of person does not wear orthosis at ordinary times, it is necessary to give people proper massage and muscle strength training.
■ For people with intermittent spasms and unstable tension, they often feel uncomfortable at the beginning of wearing, and it will not take long to adapt to the treatment described above.
■ Precautions when sitting for a long time: The stability of wearing AFO on the ground will be very poor, because there is often a tendency to "W" sitting, which will be limited by orthosis. Therefore, people must sit on the chair or take off the AFO when sitting for a long time.
Hemiplegic patients need ankle-foot orthosis
For those who have already suffered from deformities, the use of orthosis can promote rehabilitation and correction of deformities.
For bedridden patients, it plays a role in preventing foot droop and varus deformity. Most patients in spastic period are developed from the relaxation period, so it is very necessary to prevent in advance. Since the rehabilitation process is long, it is doubtful whether the patient can persist in good rehabilitation exercise at home. If the patient has bad gait for a long time, it will eventually lead to the development of joint deformity. In order to avoid this kind of situation to the greatest extent, orthosis is recommended.
It can be seen that the correct wearing of orthoses can fully realize the design concept of orthopedics and enable the users of orthoses to get the best recovery with the help of orthoses. Therefore, we must learn the correct wearing and using methods. At the same time, with the recovery of the disease, the orthosis should be continuously followed up and adjusted to achieve the best correction effect.
