Abstract:〔Abstract〕 Objective To analyze the application advantage of personalized muscle strength exercises in rehabilitation of lumbar disc herniation (LDH). Methods A total of 70 patients diagnosed with LDH who received surgical treatment in Zhengzhou Orthopedics Hospital from January 2021 to April 2022 were selected and divided into a control group and an observation group by random number table method, with 35 cases in each group. When receiving postoperative rehabilitation treatment, patients in the control group received routine rehabilitation treatment, and patients in the observation group were supplemented with personalized muscle strength exercises on the basis of the control group, and the overall rehabilitation effect of the two groups of patients were compared. Results After intervention, the pain score of the observation group was lower than that of the control group, and the degree of straight leg elevation was higher than that of the control group, the differences were statistically significant (P < 0.05). After intervention, the dysfunction index of the observation group was lower than that of the control group, and the lumbar spine score was higher than that of the control group, the differences waere statistically significant (P < 0.05). The excellent and good rate of the observation group was 97.14 %, higher than 82.86 % of control group, and the difference was statistically significant (P < 0.05). Conclusion After LDH surgery treatment accepted rehabilitation therapy, personalized muscle strength exercises have clinical application advantages, which can guarantee the effect of rehabilitation therapy, improve pain and promote the recovery of waist and leg function.
