Description

Rehabilitation training device for stretching feet back

Technical Field

The utility model relates to a foot rehabilitation training field specifically is foot back of body stretches rehabilitation training device.

Background

The foot dorsiflexion rehabilitation training is a link in the medical rehabilitation process, generally exists in the recovery training of the basic activity function of the foot after a foot operation or when the foot is not moved for a long time due to bed rest, the flexion and extension actions generated by the flexion and extension of the ankle are called as "flexion", and are divided into "plantarflexion" and "dorsiflexion", so-called plantarflexion of the foot, namely when the ankle is in a normal functional position, gastrocnemius muscle and achilles tendon contract to generate the movement that the instep faces downwards and the tiptoe is jacked, namely, the angle between the instep and the front of the shin is increased, and the movement is the plantarflexion of the foot; dorsiflexion of the foot, i.e., dorsiflexion, is the movement of the foot dorsum upward with decreasing angle and approaching distance between the foot dorsum and the front of the shin when the ankle is in the normal functional position and the tibialis anterior muscle is contracted.

In the process of foot dorsal extension training, muscles mainly providing foot movement power are calf triceps muscles except for the foot muscles such as gastrocnemius, achilles tendon, tibialis anterior muscles and the like, but in the prior art, the elastic ropes are usually bound on the feet to apply load to the feet, and the load of the elastic ropes cannot be adjusted in the mode of adopting the elastic ropes, so that foot resistance training with different requirements cannot be adapted, and the calf parts are not fixed when the foot dorsal extension resistance training is carried out by adopting the elastic ropes, so that the calves cannot keep stable postures in the process of foot dorsal extension movement, and the posture error of the foot dorsal extension movement is very easy to occur in the process of continuing the movement due to inaccurate muscle force or partial pain influence of muscles of a patient in the foot dorsal extension movement, particularly the calves bend laterally in the dorsal extension process, so that a plurality of muscles cannot contract along the direction of muscle fibers, because this kind of wrong motion mode probably causes the secondary injury or causes shank cramp to the muscle tissue that is in the convalescence, how to fix the shank on the basis of accomplishing the anti-resistance rehabilitation training that the foot back stretches to avoid incorrect motion posture to bring the damage or cause shank cramp to just become the problem that the rehabilitation training field of foot waited for a long time to solve to the muscle that is in the convalescence.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art and to have the orientation fixed thereby to lead to the recovery phase muscle to receive the not enough of secondary injury easily at the shank of motion at the in-process that carries out foot back of the body stretch anti resistance rehabilitation training, thereby provide a foot back of the body stretch rehabilitation training device, thereby can not cause the damage or cause shank cramp to the recovery phase muscle because the mistake of shank is hard and in making the foot back of the body stretch the motion through fixed shank.

The purpose of the utility model is mainly realized through the following technical scheme:

the foot back stretching rehabilitation training device comprises a device base, wherein at least one pair of parallel clamping columns is arranged above the device base, a gap is reserved between each pair of parallel clamping columns, a clamping plate is arranged on each clamping column and located between the parallel clamping columns, the clamping columns are fixedly connected with the clamping plates, each clamping plate forms a long straight channel above the device base, a foot back stretching load bearing mechanism is arranged on the side face of the device base, the foot back stretching load bearing mechanism is located on the side face of the device base in the extending direction of the long straight channel, a connecting rod is arranged between the device base and the foot back stretching load bearing mechanism, one end of the connecting rod is movably connected with the device base, and the other end of the connecting rod is fixedly connected with the foot back stretching load bearing mechanism.

In the prior art, foot rehabilitation training is required when the foot function needs to be recovered in the recovery period after foot injury and after long-term bed rest, common foot rehabilitation training is ankle pump movement, the ankle pump movement is movement of ankle joints and promotes blood circulation and lymph backflow of lower limbs like a pump, the ankle pump movement can be divided into two groups of movements of flexion and extension and loop winding, foot back extension training is a loop in flexion and extension, when foot back extension resistance training is performed, an elastic rope is generally adopted as a training device, one end of the elastic rope is generally tied on a foot and the other end of the elastic rope is tied on a fixture, so that the load required by the foot back extension movement can be effectively provided by utilizing the elasticity of the elastic rope, but the position of a calf is not fixed when the foot back extension training is performed by utilizing the elastic rope, and a patient with weak foot control capability is used for the foot back extension resistance rehabilitation training, therefore, the patient is easy to shake the lower leg or bend the lower leg laterally in the process of exerting force, so that the lower leg and the ankle joint can rotate relatively, muscle fibers of related muscles cannot contract along the normal direction, and the fragile muscle tissue of the patient can be easily damaged or the lower leg can be easily cramped; in the utility model, the shank is limited in the right direction by the long straight channel formed by the clamping column and the clamping plate, the trembling of the shank can be effectively weakened and the side bending of the shank can be avoided on the basis of having a support, the fixed connection between the clamping plate and the clamping column is detachable, for example, the fixing is carried out by adopting the mode of inserting holes, buckles or bolts, the clamping plate can be effectively taken down by the detachable fixed connection mode, thereby the utility model can be better maintained, the weight bearing mechanism of the back can provide the load for the foot, the aim of the stretching resistance training of the back of the foot can be achieved by resisting the load, the slight swing of the ankle joint can be effectively adapted by the movable connection of the connecting rod and the device base, the resistance injury can not be formed at the ankle joint, and the shank can be effectively fixed and stable by the combined action of the clamping column and the clamping plate, and stretch the heavy burden mechanism through the foot back that can provide the heavy burden for the foot and stretch for the back of the foot and resist the support that resistance training provided the load, stretch under the combined action of heavy burden mechanism, connecting rod and grip block at the foot back, thereby through fixed shank make the foot back stretch not cause the damage or cause shank cramp to the muscle of convalescence because the wrong effort of shank in the motion.
