Description

Ankle foot correction plate for improving enstrophe of stroke patient and helping fixation

Technical Field

The invention relates to the technical field of ankle foot correction, in particular to an ankle foot correction plate for improving enstrophe of a stroke patient and helping to fix.

Background

The inclined plate is also called as an ankle foot correcting plate, and is a method for self-drawing by utilizing the adjustable inclination angle of the inclined plate and the self gravity of the inclined plate when the inclined plate stands naturally; so as to relieve the triceps spasm of the shank, maintain/expand the activity range of the ankle joint, and prevent and correct the tiptoe, the foot varus, the foot valgus and the like to a certain extent;

in fact, a clinical ankle foot orthosis plate is typically used with a standing bed and a standing frame, placed underneath the standing bed and the standing frame. For a part of stroke patients who put the ankle foot correcting plate below the standing frame for matching use, due to the abnormity of lower limb sensory function (shallow sensation, deep sensation and composite sensation), abnormal muscle tension (overhigh or overlow), foot drop, foot inversion, achilles tendon contracture and the like of the stroke patients, when the stroke patients are matched with the standing frame for use, due to poor fixing effect, when part of patients with poorer lower limb functions are matched with the standing frame for treatment, affected feet are often positioned at incorrect positions (deviated from the neutral position and inverted in the standing process), and the correcting effect is influenced. In addition, the existing ankle foot correction plate is inconvenient to adjust and correct the inclination angle of the pronation of the foot according to the state of illness of different patients, has large limitation on correction of abnormal postures, is lack of functionality, cannot stimulate and treat the sole of the foot of the patient, and is not beneficial to improving the recovery efficiency of the patient.
