Description
Technical field
The present invention relates to rehabilitation medical instrument technical field more particularly to a kind of freedom degrees for patients with cerebral apoplexy
Adjustable ankle-foot orthosis.
Background technique
Cerebral apoplexy is also known as " apoplexy ", " cerebrovascular accident ", is a kind of acute cerebrovascular diseases, is since cerebral vessels are unexpected
Rupture causes one group of disease of brain tissue impairment because blood is caused to cannot flow into brain for angiemphraxis.Investigation display, brain soldier
In have become the first cause of first, China cause of death and Chinese adult deformity, cerebral apoplexy has disease incidence high, dead
Die rate height and the high feature of disability rate.For patients with cerebral apoplexy, muscle group (tibialis anterior) and outside muscle group (fibula length before shank
Flesh) deficiency is activated, there is muscular atrophy of disuse, instep is caused to stretch difficulty in muscle, in turn results in drop foot, drop foot is Orthopeadic Surgery
One of sign, patient's seat, two lower limb dangle naturally, such as see foot in plantar flexion position and completely cannot active dorsiflex turned over inside and outside,
It is then drop foot.Drop foot is preceding muscle group and outside the muscle group paralysis by shank, and after shank caused by muscle group spasm drawing,
It shows as being unable to dorsiflex foot, towing foot disease or the side lower limb is lifted higher when walking, always toe is first when landing
Tread surface is very unfavorable for this patient's stair activity and daily life.In recent years, many relevant medical research reports
Show that the limbs for making patients with cerebral apoplexy in treatment early stage keep function digit, facilitates the generation for preventing the bad complication of patient.
Ankle-foot orthosis is generally used for providing protection for the ankle and foot of patient, and major function is to provide plantarflexion, when
It helps the foot to be kept in the correct position when the foot of patient is lifted away from ground.And ankle-foot orthosis in the prior art, function list
One, inconvenient for use, and the freedom degree of entire orthoses is seldom, when patient carries out rehabilitation training, cannot simulate normal person completely
Gait.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of freedom degrees for patients with cerebral apoplexy can
The ankle-foot orthosis of tune, to not only be able to satisfy the fixation orthopaedic function at illness initial stage, but also can in later period rehabilitation training complete mould
The gait of quasi- normal person.
