The patient wears shoes normally during assessment, sits on a backrest chair with armrests (chair seat height is about 45cm, and armrests height is about 20 cm), and rests on the chair back with hands. If a walker (e.g., cane, walker) is used, the walker is held in the hand. A color bar or a visible thick line is attached or a marked mark is placed on the ground 3 meters away from the seat. When the tester issues a "start" instruction, the patient stands up from the back rest chair. After standing, the user walks forward for 3 meters according to the gait of walking at ordinary times, turns around after passing through a thick line or a marker, then walks back to the front of the chair, turns around again and sits down, and leans against the chair back. No help is given to any body during the test. The tester records the time (in seconds) it takes for the back of the patient to leave the seat back and sit down again (against the seat back), and the risk of possible falls during the completion of the test. Prior to the formal test, the patient is allowed to exercise 1-2 times to ensure that the patient understands the entire test procedure. Scoring criteria: (1) free movement for less than 10 seconds; (2) most of the parts can move independently in less than 20 seconds; (3) unstable activity for 20-29 seconds; (4) > 30 seconds of movement disorder. In addition to recording the time taken, the gait and the risk of possible falls during the test are scored as follows. 1, the method comprises the following steps: normal. 2, the method comprises the following steps: very slight anomalies. 3, the method comprises the following steps: mild abnormalities. 4, the following steps: moderate anomalies. 5, the method comprises the following steps: severe abnormalities.

It should be noted that, at this time, the controller does not stop recording the signals of the pressure sensors of each group, but will continue to record the pressure changes detected by the pressure sensors of each group during the whole test.

And 3, the tested person leans the back against the back of the test chair, the controller receives a pressure sensor signal in the back, when the signal is larger than a set threshold value, the controller triggers the voice prompt to prompt "please start test" (test start prompt sound), and when the tested person deviates from the back, the back pressure sensor pressure is zero, the controller triggers the timer to count [ 2 ] (test start time).

And 4, when the tested person returns to the test chair to sit on and the back is attached to the back of the test chair again, and the pressure of the back pressure sensor is larger than a set threshold value, stopping timing of the timing [ 1 ] and the timing of the timing [ 2 ]. At the same time, the controller stops recording the sensor pressure values for each group and displays the test results on the display screen, including but not limited to the following: (1) test time (timing [ 2 ]); (2) testing the preliminary time (difference between timing [ 1 ] and timing [ 2 ]); (3) hip pressure, left side armrest pressure, right side armrest pressure, left foot pedal pressure, right foot pedal pressure over time.

The flexible film piezoresistive sensor 31 in the backrest 3 is preferably 20g-10kg in measuring range and is arranged on the hard plastic backboard and under the foam cushion. The method for setting the threshold trigger control signal according to the test pressure value comprises the following steps: the pressure sensor is connected to a control circuit, which, as shown in fig. 6, is composed of a wheatstone bridge and a voltage comparator. When the test pressure value is increased to the set pressure threshold value, and the pressure sensor resistance is smaller than the set R1, the voltage comparator U1+ is higher than U1-, and a high level is output and is used as a signal for triggering a timer and a voice prompt.
