Effects of extracorporeal shock-wave therapy and ultrasound therapy on pain relief and lumbar mobility in patients with lumbar myofascial pain / 中国基层医药

ABSTRACT

Objective:To investigate the effects of extracorporeal shock-wave therapy wave (ESWT) and ultrasound therapy on pain relief and lumbar mobility in patients with lumbar myofascial pain.Methods:A total of 100 patients with lumbar myofascial pain who received treatment in The First People's Hospital of Jiande from March 2020 to March 2021 were included in this study. They were randomly divided into ESWT and ultrasound therapy groups, with 50 patients per group. The ESWT group was treated with ESWT at a frequency of 8 Hz and an energy density of 0.16 mJ/mm 2 once a week. The ultrasound therapy group was treated with ultrasound therapy at a frequency of 1.0 MHz and an intensity of 1.0 W/cm 2, once a day, 5 times a week, for 4 consecutive weeks. Therapeutic effects, pain relief and lumbar mobility improvement were observed in each group. Results:Total response rate in the ESWT group was significantly higher than that in the ultrasound therapy group [92.00% (46/50) vs. 76.00% (38/50), χ2 = 4.76, P < 0.05). After treatment, Visual Analogue Scale (VAS) score and Oswestry Dysfunction Index (ODI) score in the ESWT group were (2.56 ± 1.03) points and (20.22 ± 3.45) points, respectively, which were significantly lower than (3.83 ± 1.12) points and (25.13±3.72) points ( t = 5.90, 6.84, both P < 0.001). After treatment, anterior flexion, posterior extension, and lateral flexion of the lumbar spine in the ESWT group were (68.32 ± 8.67)°, (51.13 ± 6.56)°, (69.43 ± 8.27)°, respectively, which were significantly higher than (61.65 ± 8.51)°, (47.22 ± 6.50)°, (64.16 ± 7.69)° in the control group ( t = 3.88, 2.99, 3.30, all P < 0.05). Conclusion:Compared with ultrasonic therapy, ESWT for lumbar myofascial pain can better relieve pain, improve lumbar mobility, and enhance clinical efficacy.
