5.1. Passive traction SEMG data of the triceps crus in both groups are presented in the third row of 
tibialis anterior muscle, stroke
STROKE, CONTRACTION
Compared with the observation group, the SEMG of the treatment group was higher.The treatment group was 9.33 (88.44–7.47) and the control group was 4.17 (27.3–6.64).The difference between the 2 groups was statistically significant (The surface electromyography during passive traction of the triceps crus indicated triceps crus muscle tension. The above data showed that the triceps calf muscle tension of the treatment group was lower than that of the observation group, and the difference was statistically significant.Ratio of passive extension to passive relaxation SEMG data of the triceps crus in the 2 groups are presented in Row 4 of Table Compared with the observation group, the value of the treatment group was higher.The treatment group 3.05 (5.99–1.09).The control group 0.07 (2.57–0.68).The difference between the 2 groups was statistically significant (To reduce the measurement error, the triceps calf muscle tension in the treatment group was lower than that in the observation group, and the above data showed that the triceps calf muscle tension in the treatment group was lower than that in the observation group, and the difference was statistically significant.Row 5 of Table Compared with the observation group, the EMG of the treatment group was higher.The treatment group was 24.17 (9.40–28.7) and the control group was 5.24 (0.40–16.09).The difference between the 2 groups was statistically significant (The surface electromyography during the active contraction of the anterior tibial muscle suggested the strength of the anterior tibial muscle. The above data showed that the strength of the anterior tibial muscle in the treatment group was higher than that in the observation group, and the difference was statistically significant.Row 6 of Table Compared with the observation group, the value of the treatment group was higher.The treatment group was 13.79 (2.53–33.7) and the control group was 2.19 (1.1–33.7).The difference between the 2 groups was statistically significant (The comparison of the data obtained during active contraction of the tibialis anterior muscle with the data obtained during relaxation was performed to reduce measurement error. The above data showed that the muscle strength of the tibialis anterior muscle in the experimental group was higher than that in the observation group during active contraction, and the difference was statistically significant.Hemiplegia patients’ high leg triceps muscle tension is one of the main factors that limits walking.This is related to the high frequency of intensive training. The training frequency of conventional rehabilitation training for the tibialis anterior muscle is often less than 100 times per day, while the training frequency designed in this study is 300 times per day, which is several times higher than that of conventional rehabilitation training, and the high frequency of intensive training can improve patients’ limb control.This study is similar to the article by Yoo DY from Korea “Impact of intensive rehabilitation on long-term prognosis after stroke: A Korean nationwide retrospective cohort study,” which shows that intensive rehabilitation has long-term positive effects on stroke patients.The intensive training method designed in this study is simple and easy to learn, and patients or their family members can master it proficiently after training. Patients can train independently at any time, with strong active participation. However, routine rehabilitation training involves many complex movements, in which patients and their family members have a limited grasp of the training, and active participation is weak. The rehabilitation effect of patients with good active participation is better than that of patients with weak active participation.Hemiplegia requires long-term treatment, and many patients cannot be treated in medical institutions for a long time. After mastering this intensive training method, patients and their family members can train at home by themselves, which can reduce medical expenses and the risk of poverty caused by illness.However, intensive training of the tibialis anterior muscle requires a high degree of cooperation among the patients, therapists and their families. During training, concentration should be on the muscle, movement should be slow, patients’ tolerance should be taken as appropriate, and overtraining should not aggravate the injury of patients.
