This invention relates to the field of medical technology and discloses a lower limb ligament stretching training device, comprising two mounting frames with armrests, a base at the bottom of each frame, and two sponge boards on the base. Bolt holes are symmetrically arranged around the base. The footrest housing allows the patient to place their feet while standing. The angle is adjustable via a drive assembly, and a cylinder drives a pedal to vibrate, providing low-intensity exercise of the ligaments around the ankle and knee joints, as well as the fascia of the lower leg and anterior thigh, avoiding static stretching injuries. The seat body allows the patient to rest at any time. The footrest frame adjusts its orientation via a foot-flipping assembly and a connecting frame, and then reciprocates via the foot drive assembly, allowing the patient to straighten their legs and stretch ligaments while sitting. It is suitable for both standing and sitting scenarios, effectively improving ligament flexibility and extensibility, and adapting to different usage needs.
