Abstract:

Objective

To study the therapeutic effect of ultrasound-guided PRP injection combined with Mulligan dynamic joint mobilization for the treatment of acute ankle sprain.

Methods

90 patients with acute ankle sprain in Shaanxi Provincial Traditional Chinese Medicine Hospital from February 2022 to March 2024. Among them, there were 57 males and 33 females; age range of 40~70 years, with an average of (41.85±7.34) years. According to the random number table method,they were divided into research group and control group, 45 cases each. Both groups were given etofenate gel, on this basis, the control group was treated with Mulligan dynamic joint mobilization, the research group used ultrasound-guided PRP injection combined with Mulligan dynamic joint mobilization for treatment. Both groups were treated for one month, the excellent and good ankle joint function rates, AOFAS scores, VAS scores, and active range of motion of ankle joint (dorsiflexion, plantarflexion, varus, valgus) were compared between two patient groups after 1 months of treatment, the hemodynamic parameters of the dorsal foot artery on the affected side [peak systolic blood flow velocity (SF), mean blood flow velocity (TAM), resistance index (RI)] were compared after 1 months of treatment.

Results

The excellent rates of ankle joint function in the study group was higher than that in the control group, and the AOFAS score, ankle joint active range of motion, SF, and TAM levels were higher than those in the control group (P<0.05); the VAS score and RI level of the study group patients were lower than those of the control group (P<0.05).

Conclusion

Ultrasound guided PRP injection combined with Mulligan dynamic joint mobilization can effectively improve ankle joint function, alleviate pain, promote blood circulation, and have significant clinical efficacy in patients with acute ankle sprain.
