Abstract
Description
Technical Field
[0001] The utility model relates to the field of foot prevention and correction equipment, and more specifically, to a correction device for preventing foot drop. Background Art
[0002] At present, the commonly used method for clinical prevention and correction of foot drop is to use an orthotic structure. The current orthotic structure adopts a U-shaped bracket (high-density sponge pad) and a foot support vertically arranged inside the bracket. The support keeps the foot fixed in a 90° neutral position. It is suitable for patients who are bedridden for a long time to prevent foot drop, patients with Achilles tendonitis, patients with gastrocnemius spasm, patients with acute ankle sprains and patients recovering from fracture surgery;
