Description

Technical Field

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

[0002] Foot drop is one of the signs of orthopedic surgery. When the patient sits, the lower limbs hang naturally. If the foot is in plantar flexion and cannot actively dorsiflex, invert, or evert, it is foot drop. This sign can be seen in sciatic nerve palsy and common peroneal nerve palsy. 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] Currently, a common correction method is to wear a foot support on the foot, such as a foot drop support described in the patent document CN202960844U, which includes a foot support, a soft pad, and a strap.
