Embodiment 1
[0031] A kind of embodiment of the method for assessing trunk muscle cerebral cortex motor representative area of the present invention, comprises the following steps (flow process is as follows figure 1 shown):
[0032] (1) The subject sits and wears a prepared standard network positioning cap (such as figure 2 ), find the best stimulation point, determine the resting motion threshold and the best stimulation intensity;
[0033] (2) Instruct the subject to use the biostress feedback instrument (such as image 3 ) to 50±2mmHg to make the transversus abdominis or multifidus complete about 10% of the maximum voluntary isometric contraction, perform transcranial magnetic stimulation on each 1×1cm cell on the positioning cap, and stimulate each grid 10 times, 5 out of 10 times the motor-evoked potential amplitude ≥ 50μV was considered as effective stimulation, and the latency and amplitude of the motor-evoked potential of effective stimulation were recorded;

[0039] The test-retest reliability of embodiment 2 biological pressure feedback instrument
[0040] Subjects: This study recruited 31 healthy young volunteers from our hospital interns, including 6 males and 25 females, aged 22.23±1.96 years old, weighing 56.65±8.98kg, height 164.19±7.54cm, BMI 21.00±2.59 kg / cm 2 . Inclusion criteria: ①BMI is ±20% standard; ②Right-handed; ③No musculoskeletal system disease, nervous system disease or mental and psychological disease; ④No history of abdominal, lumbar / sacral trauma, or surgery; ⑤No scoliosis ; ⑥ No muscle fatigue and low back pain in the past 6 months, and no strenuous exercise within 24 hours before the experiment. Exclusion criteria: ① Those who cannot complete the action tasks correctly; ② Female menstrual period; ③ Pregnant women. This experiment was approved by the Ethics Committee of our hospital, and all subjects signed informed consent.
