Abstract

The invention provides a multi-pose lower limb training device with an adjustable track. The device comprises a foot end track generating mechanism, a lower limb angle adjusting mechanism, a sitting posture auxiliary training device and a standing posture auxiliary training device. A pair of leg side protective boards are symmetrically arranged on the inner side of the standing posture training device, the foot end track generating mechanism is arranged inside the leg side protective boards, an eccentric wheel is driven by a driving device to rotate, a parallelogram mechanism is driven to movethrough composite transmission of a crank-rocking bar mechanism and a five-rod mechanism, pedals located outside the leg side protective boards are hinged to the lower end of a track output rod of the parallelogram mechanism and synchronously move along with the track output rod, the pair of leg side protective boards can be driven by the lower limb angle adjusting mechanism to swing back and forth to the inclined state, and the sitting posture auxiliary training device and the standing posture auxiliary training device can move relatively. Humanlike gait foot end track training of differenttypes and amplitudes can be provided.

Description

technical field

[0001] The invention relates to the fields of rehabilitation medicine and fitness equipment, and more specifically relates to a multifunctional lower limb training device capable of realizing different types and different amplitudes of gait-like training trajectories. Background technique

[0002] For paralyzed patients after acute clinical treatment such as surgery, rehabilitation is the main treatment, and it is usually a fairly long-term continuous process. In the traditional rehabilitation treatment, the patient's exercise training mainly relies on the manual assistance of the physical therapist, which is time-consuming, the training strategy is relatively simple, and the cost is relatively high. Moreover, during the training process, it is often difficult to maintain good consistency in the movement trajectory of the affected limb and the strength applied to the affected limb. The use of rehabilitation robots to assist patients in exercise training can ...
