Description

Technical Field

[0001] The utility model relates to the technical field of children's rehabilitation, in particular to a pediatric multifunctional four-wheeled walker. Background Art

[0002] Poliomyelitis (polio) generally refers to poliomyelitis (acute infectious disease). Poliomyelitis is an acute infectious disease caused by the polio virus that seriously endangers children's health. The polio virus is a neurotropic virus that mainly invades the motor neurons of the central nervous system, mainly damaging the anterior horn motor neurons of the spinal cord. Most patients are children aged 1 to 6 years old. The main symptoms are fever, general discomfort, limb pain in severe cases, irregular distribution and varying degrees of flaccid paralysis, commonly known as polio;

[0003] For polio patients, some rehabilitation tools in the form of power-assisted bicycles are generally used in the later stages of rehabilitation. However, the power-assisted bicycles for rehabilitation currently on the market are not adjustable enough and cannot be slightly adjusted according to the patient's actual body shape, resulting in less than optimal rehabilitation effects. The soft seat cushions configured in them make it easy for children with cerebral palsy, muscular atrophy and polio to have incorrect postures during training, which can easily cause the training to fail to achieve the expected results.

[0004] Therefore, a kind of pediatric multifunctional four-wheeled walker is needed to improve the above-mentioned problems. Utility Model Content
