The invention discloses a household 3R open chain foot driving type lower limb rehabilitation training device and a using method thereof. An existing lower limb rehabilitation training device is complex in control and difficult to meet the requirement for ankle joint posture change. A first shell assembly comprises a first shaft, a first lower shell, a first upper shell, a second shaft, a third shaft, a first non-circular gear, a second non-circular gear, a third non-circular gear, a fourth non-circular gear, a fifth non-circular gear and a sixth non-circular gear. The second shell assembly comprises a second lower shell, a second upper shell, a third shaft, a first belt wheel, a synchronous belt, a second belt wheel and a fourth shaft. The first shaft is driven by the power input assembly and drives the pedal to rotate at different speeds with the second lower shell and the second upper shell through all stages of transmission, so that the included angle between the pedal and the second lower shell is periodically changed in the mode that the included angle is gradually increased and then gradually decreased. Only one power source is needed to achieve the similar elliptic track of the ankle joint, the posture change requirement of the ankle joint can be met, and training is in place.
Description
technical field [0001] The invention belongs to the field of rehabilitation mechanical devices, and in particular relates to a household 3R open-chain foot-driven lower limb rehabilitation training device and a use method thereof. Background technique [0002] According to the World Health Organization, from 2000 to 2050, the population over the age of 60 will increase from 11% to 22% of the total population, and the population aging will continue to accelerate. With the problem of population aging, stroke is a common and frequently-occurring disease in clinical practice. About 30% of the survivors cannot recover independent walking ability, and some patients who regain walking ability walk with hemiplegic gait. Medical research shows that scientific and correct lower limb rehabilitation training is very important for stroke survivors to restore their walking ability. [0003] The traditional lower limb rehabilitation training is mainly one-on-one training between medical p...
