AI doctor Gait abnormalities are now for you

Gait abnormalities  of  rehabilitation robots can be seen in many diseases of the nervous system or other systems. Some typical abnormal gaits have suggestive significance for some specific diseases and can be diagnosed by inspection. For some atypical gaits, careful examination must be made, and through analysis and synthesis, it is also helpful for diagnosis. The clinical classification of gait abnormality should be combined with the etiology.According to etiological diagnosis, the treatment is mainly aimed at the primary disease. Today, Manufacturer of rehabilitation treatment equipment of AI Doctor tells you what are the common clinical abnormal gaits.

Gluteus maximus (hip extensor) gait. If the gluteus maximus is weak, the heel often forces the chest backward, so that the gravity line falls behind the hip joint to maintain the passive extension of the hip joint. In the middle of standing, the knee joint is straightened to form a gluteus maximus gait with chest raised, waist raised and abdomen raised.

Gluteus medius gait. Gluteus medius paralysis is mostly caused by poliomyelitis. When one side of the gluteus medius is paralyzed, the lateral stability of the hip joint is affected, which is manifested by the lateral bending of the trunk of the affected leg to the affected side when standing, so as to avoid excessive descent of the pelvis on the healthy side and maintain balance. When the gluteus medius muscles on both sides are damaged, the gait is special, and when walking, the upper body swings left and right alternately, like a duck.Therefore, it is also called duck step.

3. Quadriceps gait. In patients with quadriceps femoris paralysis, the stability of the affected leg during standing and knee extension is affected, which is manifested by the extension of the hip joint by the gluteus maximus to compensate for the function of the quadriceps femoris, and the passive extension of the knee joint, resulting in recurvatum. If the hip extensor muscles are weak, the patient should bend over and press the thigh with his hand to straighten the knee.

4. Parkinson's gait. Parkinson's gait is a very rigid gait. It was characterized by difficulty in starting walking, disappearance of alternate steps of both lower limbs, forward inclination of trunk, mild flexion of hip and knee joints, no plantar flexion of ankle joints, foot rubbing on the ground, and short stride. As the trunk leans forward, the center of gravity of the body moves forward. In order to maintain balance,The patient walks forward rapidly with small strides, unable to stop or turn at will, showing a forward or flustered gait.

5. Pain-reducing gait. When pain occurs in one lower limb, it often presents a pain-relieving gait to avoid pain, which is characterized by a shorter standing time on the affected side to minimize the weight-bearing of the affected limb and a shorter stride. In addition, patients often press the painful part with one hand and stretch the other upper limb. Different parts of the pain, the performance may be different. In patients with hip pain, the ipsilateral shoulder descends when the affected limb is weight-bearing.The trunk is slightly inclined, the lower limb of the affected side is in external rotation and flexion, and the heel should be avoided as far as possible. Patients with knee pain have their knees slightly bent and walk with their toes on the ground.

6. Hemiplegic gait. Hemiplegic gait refers to the gait formed by normal limbs on one side and paralysis of limbs on the other side due to various diseases. Its typical features are that the range of flexion of the affected knee joint is reduced due to stiffness, and the affected ankle joint is plantar flexion and varus. In order to make the lower limb of the paralyzed side step forward, the shoulder joint of the affected side descends and the pelvis compensates for the elevation.Abduction and external rotation of the hip joint make the lower limb of the affected side draw a semicircle through the lateral side to bring the lower limb of the affected side forward, so it is also called circle gait.

7. Scissors gait. Scissors gait is the typical gait of spastic cerebral palsy. Because of the spasm of adductor muscle of hip joint, when walking, the lower limbs step forward and inside, the inside of knees often rub and collide with each other, the toes touch the ground, showing scissors step or cross step, and it is difficult to walk when the cross is serious.

8. Cross-threshold gait. In order to lift the toe off the ground, the patient with foot drop lifts the affected limb very high, as if crossing the old threshold. It is seen in patients with common peroneal nerve palsy.

9、Short leg gait. The affected limb is shortened by 2. For those above 5 cm, the ipsilateral pelvis descends when landing on the side, resulting in ipsilateral shoulder tilt descent, contralateral leg hip and knee excessive flexion, and ankle excessive dorsiflexion. If it is shortened by more than 4 cm, the lower limb of the shortened side walks on tiptoe, and its gait is collectively referred to as short-leg gait.

10、Cerebellar ataxia gait. Cerebellar ataxia gait is caused by cerebellar dysfunction. When the patient walks, the two upper limbs are abducted to keep the body balanced, the distance between the two feet is too wide, the legs are lifted high, and the feet fall to the ground heavily; Do not go in a straight line, but in a curve or in a "Z" ""; Because the center of gravity is not easy to control, it is unstable to walk like a drunk, so it is also called drunken gait or drunken gait.

11. Gait with crutches. If one or both lower limbs are unable to bear weight during walking due to various reasons, crutches should be used to assist walking and the gait of holding crutches. According to the position relationship between crutches and lower limbs, the gait of walking with crutches is divided into two-point step, three-point step, four-point step, step to step and step over step.
