Bed-type lower limb linkage gait simulation training equipment

Abstract

The invention provides a bed-riding lower limb linkage gait simulation training device, which comprises a base, a driving device, a transmission device, a sliding device and a foot fixing device. The driving device is arranged in the base. The transmission device is arranged on the base, and driven by the driving device to be rotatable around the first axis. The sliding device is arranged on the base. The front end of the foot fixing device is rotatably connected to the transmission device with the second axis as an axis, and the rear end is slidably connected to the sliding device, wherein the first axis is parallel to and spaced apart from the second axis. The device can generate dorsiflexion/plantar flexion of the ankle joint with the movement of the lower limbs, forming a linkage of lower limbs that simulates gait, and maximally solves the demand for compound ankle and knee joint movement during bed-ridden lower limb training. The bed-mounted lower limb linkage gait simulation training device can provide very effective assistance to the rehabilitation training of patients with motor function impairments caused by brain injuries.

Description

technical field [0001] The invention relates to the field of rehabilitation training, in particular to a bed-riding lower limb linkage gait simulation training device. Background technique [0002] In recent years, motor function impairment caused by brain injury, such as stroke, cerebral palsy, traumatic brain injury, multiple sclerosis, spinal cord injury, and senile joint stiffness, has affected the lives of many people. Taking stroke patients as an example, stroke patients often experience fragility or muscle weakness after the acute phase due to disturbances in the nervous system, more spasticity associated with increased muscle tone, and disrupted muscle use and worsened motor control can be seen in Developing 1 to 4 weeks after a stroke, spasticity and poor motor control may further contribute to muscle imbalances and imbalances between opposing muscles. [0003] In addition, prolonged inactivity during the acute phase may exacerbate muscle weakness and joint contrac...

Problems solved by technology

However, the existing bicycle type rehabilitation equipment mainly trains the hip joint and knee joint, and the training of the ankle joint is very limited.

Taking stroke patients as an example, if the ankle joint is not trained enough, deformity of the ankle joint and foot or a stiff ankle joint may develop over time, such as frequent foot drop, spasticity and inversion , severely impedes patient movement and affects gait, thereby reducing stride safety and balance
