A strength tester for foot metatarsophalangeal joints comprises a base plate, a pedal, a seat, a tension sensor and a computer. The seat is fixedly arranged at the back end of the base plate, a leg fixing frame is arranged on the base plate and is located in front of the seat, a suspension bracket is arranged at the front end of the base plate and is located in front of the leg fixing frame, the upper end of the tension sensor is hung on the suspension bracket, the back end of the pedal is hinged to the front portion of the base plate, the front end of the pedal is connected with the tension input end of the tension sensor, and the signal input end of tension sensor is connected with the computer through a signal line. According to the strength tester for the foot metatarsophalangeal joints, the pedal is used for transmitting the motion of the metatarsophalangeal joints, the tension sensor and the computer are used for metering and processing the bending strength data of the metatarsophalangeal joints, the leg fixing frame and a heel limiting board are used for removing the disturbance of the motion of other joints, the data collection process is simplified, the collection repeatability is good, the data are accurate, and the strength tester for the foot metatarsophalangeal joints is proven to be reliable and stable.
Description
Technical field: [0001] The invention relates to the field of machinery, in particular to physical training and testing equipment, in particular to the strength training and testing technology for the metatarsophalangeal joint of the foot, in particular to a strength tester for the metatarsophalangeal joint of the foot. Background technique: [0002] The metatarsophalangeal joint belongs to the front part of the foot joint and is composed of the metatarsal head and the base of the proximal phalanx. Slight abduction (expansion of the five phalanges) and adduction (approaching of the five phalanges) of the phalanx. In addition, the flexion and extension of the metatarsophalangeal joints make the metatarsals move downward and upward, which can increase or decrease the arc of the arch of the foot, make the front of the foot concave or collapse, and change the shape of the arch of the foot. Furthermore, the metatarsophalangeal joints have a greater range of extension than flexio...
