Description

Technical Field

[0001] The utility model relates to the technical field of foot drop care, in particular to a severe foot drop care device. Background Art

[0002] Foot drop is one of the signs in orthopedic surgery. When the patient sits, the lower limbs hang naturally. If the feet are in plantar flexion and completely unable to actively dorsiflex, invert, or evert, it is foot drop. This sign can be seen in sciatic nerve paralysis and common peroneal nerve paralysis. In the former, the toes cannot dorsiflex or plantar flex, while in the latter, the toes can plantar flex. This can be used to distinguish the two. In addition, this sign can also be seen in poliomyelitis, progressive muscular dystrophy, hypokalemic periodic paralysis, and lower limb paralysis.

[0003] Patent authorization announcement number CN211271852U discloses a device for caring for critically ill patients with foot drop, comprising an adjustable support plate, a foot support plate, and a reduction motor.
