Description

Ankle-foot orthosis for improving paddling gait

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to ankle foot orthopedic ware for improving draw circle gait.

Background

The high disability rate after stroke is always a hot point of domestic and foreign research, the falling and limited range of motion caused by the reduction of the abnormal posture regulation and control capability of gait after stroke causes serious physical and psychological influence on patients, the burden of family and social care is increased, 60% of patients can leave serious dyskinesia after stroke, the dyskinesia after stroke is mainly the change of movement patterns caused by the abnormal increase of muscular tension, the abnormal movement of lower limbs is mainly the movement patterns mainly changed by quadriceps femoris, triceps surae and tibialis muscle tension, the patients mainly show the movement patterns of hyperextension of knees and drop foot inward during movement, and the typical gait characteristics under the movement patterns are 'circle-drawing gait'; the foot-ankle-foot part is the terminal of a sports chain and plays an important role in daily life and sports; in the normal walking process, when the ground is initially landed, the heel slightly pronates, the outer side of the heel is in contact with the ground, and the rapid pronation of feet is favorable for absorbing impact brought by body pressure; the ankle joint and subtalar joint reactions have an effect on both ankle joint plantar flexion and subtalar joint eversion; in the walking cycle, firstly, the lateral edge of the heel touches the ground at the early stage of the load phase, the whole heel touches the ground along with the eversion of the calcaneus, when the heel is slightly everted and the middle foot is rotated forwards at the time of complete load, the maximum pressure of the flattening of the arch of the foot reaches the front supporting point of the horizontal arch of the first metatarsal head; meanwhile, the first metatarsophalangeal joint is ensured to complete propulsion in the swing period;

as the neuromuscular control ability of the patient is reduced, the stability of the knee joint is damaged, or the lower limb control ability is reduced, in order to ensure the stability of the lower limb of the knee joint, the knee hyperextension phenomenon can occur to ensure the sufficient stability; after the lower limb muscle training is carried out after the stroke, the muscle strength around the proximal joint of the affected limb and the stability of the knee joint are well improved after the rehabilitation training of the joint stability; however, the symptoms of knee hyperextension in some patients are not improved; studies by scholars have found that the movements of the knee joint are closely related to the movements of the ankle joint, and that foot drop and group varus may be potential contributing factors to the occurrence of knee hyperextension; after stroke, when triceps of the leg or tibialis anterior muscle is weak, the forefoot touches the ground first at the initial stage of the supporting phase, the ground reaction force borne by the forefoot after touching the ground moves the tibia backwards to generate a backward stress to form a knee stretching moment, and the knee joint lacking the control capability is kept stable through a locking mechanism, so that the knee is hyperextended; the more common method for correcting drop foot mainly comprises the wearing of stretching triceps surae muscle or AFO by manipulation; however, most AFO brace segments currently complain of discomfort, which may be associated with the brace stimulating the sole of the foot to aggravate spasms; clinical observation shows that the patients are often accompanied by more obvious foot varus and toe muscle spasm; at present, no brace for improving gait after cerebral apoplexy by foot varus exists. In earlier researches, after the elastic bandage is wound to correct the foot varus and foot drop, the sole pressure of a patient in walking is obviously improved, but the method for winding the elastic bandage has higher requirements on a manipulation, influences the risk of blood circulation at the far end of a foot and is expensive, the elasticity is reduced after cleaning, and the curative effect is influenced;

therefore, it is desirable to design an ankle-foot orthosis for improving the paddling gait caused by the foot varus after stroke to solve the above problems and relieve the pain of the patient.
