Background: Ankle sprain is one of the most common sports injuries and accounts for 10 to 30 percent of sports injuries, especially in athletes. This injury can lead to pain, imbalance, and movement restriction, and therefore has a significant impact on athletes' performance. Therefore, the aim of this study was to investigate the effect of dry needling on tissue repair of ligamentous injury in the acute phase of ankle sprain.
Methods: This double-blind clinical trial study was conducted on 52 patients with ankle sprains at Imam Reza Hospital in 2023. Patients were divided into two groups: control and intervention. The control group received conventional treatment including medication and splints, while the intervention group received dry needling in addition to conventional treatments. Data analysis was performed using SPSS version 21 software and descriptive statistics and inferential statistical tests at a significance level of P<0.05.
Results: The results showed that the intervention group showed significant improvement in pain (P=0.002), activities of daily living (P<0.001), sports activities (P<0.001), plantar flexion (P=0.027), dorsiflexion (P=0.003), inversion (P=0.012), and edema (P=0.005) compared to the control group. However, there was no significant difference in symptom severity (P=0.752) and quality of life (P=0.348) between the two groups. Overall patient change analysis showed that most patients in the intervention group improved, while only 7.7% in the control group improved.
Conclusion: A combination of splinting, medication, and dry needling can be effective in improving pain, daily activities, exercise and recreation, range of motion, and edema in patients with ankle sprains. These findings can provide a basis for implementing new treatment protocols for the management of ankle sprains in athletes and other injured patients. It is recommended that further studies be conducted on the long-term effects of dry needling and other therapeutic interventions to further identify their potential to accelerate the recovery process in patients.
