Embodiment Construction

[0010] The human foot is a physiological system composed of bones, joints, muscles, and ligaments. The bones bear the pressure, the muscles contract to generate power, and the tendons and muscles realize the fixation and connection of the joints. When a person is standing, the heel tubercle and the three supporting points of the foot are stressed at the same time, and the distribution of the force is similar to figure 1 shown.

[0011] When patients with ankle joint injuries are in the rehabilitation period, the ankle and lower leg are fixed in a bracket, so the 3R relative rotation angle is approximately zero. In order to ensure the balance of the patient's affected limb, a force-measuring plate with four force sensors is fixedly installed at the bottom of the bracket of the rehabilitation equipment to measure the rehabilitation force of the ankle joint. Ankle joint rehabilitation force measuring device, including a bracket, a measuring board is fixedly installed at the bott...

Abstract

The invention provides an ankle joint recovery stressed-force measuring device. The ankle joint recovery stressed-force measuring device comprises a bracket; a measuring plate is fixedly mounted at the bottom of the bracket; a first force sensor, a second force sensor, a third force sensor and a fourth force sensor are arranged on the measuring plate; the force sensor is a resistance strain sensor; two resistance strain sensors are symmetrically mounted under heel node landing positions, and two resistance strain sensors are mounted at the landing positions of the first head of phalanx and the fifth head of phalanx, respectively; the device further comprises a measuring device controller which is glued to the shank portion of the bracket by use of an adhesive tape; the first force sensor, the second force sensor, the third force sensor and the fourth force sensor are connected to an amplifier for inputting into a single chip MSP430F4270IDL, respectively; the single chip is connected with an LCD, a key and an audible and visual alarm, respectively; the measuring device communicates with an upper computer by use of a wireless module PTR2000. The ankle joint recovery stressed-force measuring device realizes indirect measurement of ankle joint recovery stressed force and torque and is convenient for patients to control the recovery strength under the guidance of a doctor.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for ankle joint rehabilitation force. Background technique [0002] Rehabilitation medicine studies have shown that appropriate bone stress stimulation in functional rehabilitation training can accelerate tissue healing and help restore the proprioception of ligaments, speed up the recovery of patients, and prevent repeated sprains caused by ankle joint instability. Therefore, the sports rehabilitation system CPM machines are widely used at home and abroad. However, since it is difficult to directly measure the force of ankle joint rehabilitation, the CPM machine does not have the ability to measure the force of ankle joint rehabilitation online. Clinicians can only rely on experience to guide patients with lower limb weight-bearing bone fractures to do rehabilitation training, and patients can only control the intensity of ankle joint rehabilitation through subjective fe...
