Ankle joint isometric muscle force testing device

The utility model discloses an ankle joint isometric muscle force testing device, which comprises a pulling/pressing force sensor, a concave support, a concave pedal frame, first chutes, screw knobs, a splint type fixing plate, pedal connecting rods, pedals and third chutes. The pulling/pressing force sensor is electrically connected with a computer, the concave support and the concave pedal frame are fixed onto a bottom frame, the first chutes are arranged on both two lateral plates of the concave support, the screw knobs arranged inside the first chutes are used for being connected with upper connecting rods of the sensor, the splint type fixing plate for fixing the sensor is arranged between the two upper connecting rods of the sensor, the pedal connecting rods and the pedals are sequentially fixed onto the two lateral plates of the concave pedal frame, two lower connecting rods of the sensor are arranged on the pedals, a sensor force bearing plate is arranged between the two lower connecting rods of the sensor, and the third chutes arranged on the pedals are used for adjusting effective lengths of the lower connecting rods of the sensor. The ankle joint isometric muscle force testing device is mainly used in synchronous measurement of force, integrated myoelectricity and central frequency in a joint angle with the maximum ankle joint dorsiflexion force value. The sensor of the testing device is the pulling and pressing force sensor and can directly obtain measurement result data by processing of the computer after standardization or calibration.
