The invention relates to the technical field of
rehabilitation training devices, in particular to a
leg muscle rehabilitation training device which comprises a bottom plate, a supporting plate, a seat plate and a leg supporting plate. The first end of the leg supporting plate is provided with a foot placing groove, and the lower side of the leg supporting plate is connected with a supporting frame. An opening and closing
assembly is arranged between the second end and the seat plate and used for driving the leg supporting plates to be opened and closed alternately. The supporting plate is connected with the fixing frame, the top of the supporting plate is provided with a flexion-extension
assembly, one side of the bottom away from the rollers is provided with a resistance-increasing
assembly, one side of the resistance-increasing assembly is provided with a resistance assembly, and an adjustable resistance source is provided. The trainer integrates alternate opening and closing and flexion and extension functions, solves the problem that a traditional instrument is single in training mode, comprehensively exercises
leg muscle groups, and promotes balanced development of
lower limb muscle strength. And an adjustable resistance mechanism can flexibly adjust the
training intensity according to the
rehabilitation stage, so that individual requirements are met. In addition, through the design of a buffer structure, action indication, a backrest grip and the like, the use comfort and safety are improved, and therefore the effect and experience of
rehabilitation training are integrally improved.
