Background
The most flexible part of the human hand is the hand, and many important tasks are performed by hand operation. Once the hand function cannot be used normally, huge inconvenience is necessarily brought to life and work. Hemiplegia is a functional disorder of the organism caused by acute cerebrovascular diseases, also called hemiplegia, which can cause movement disorder of parts such as upper and lower limbs, facial muscles, lingual muscles and the like on one side of a human body, and particularly has different degrees of distinction, such as paresis, incomplete paralysis, total paralysis and the like. The muscle force feedback forms of delayed hemiplegia and spastic hemiplegia, the delayed hemiplegia mainly shows the phenomenon of muscle paralysis caused by low muscle tension, the spastic hemiplegia mainly shows the remarkable increase of muscle tension, the upper limb shows the state of bending and the lower limb shows the state of straightening, and the fingers show the state of bending, so that the hand is straightened passively and has the stiffness resistance.
In the current rehabilitation physiotherapy of spastic hemiplegia, the fingers are required to be kept in a straightened state by an appliance so as to avoid the problem of muscular atrophy caused by contraction of hand tendons due to long-term buckling of the finger parts. In the prior art, the fingers of a patient are straightened mainly through a retainer, such as the Chinese patent with the application number of 201210448398.6, but the structure is relatively complex, the control is not flexible enough, such as the Chinese patent 20062013590.
