Effects of dry needling on symptomatic hallux valgus: A randomized single blind clinical trial

Objectives: The purpose of the present study was to determine the short and medium effects of dry needling (DN) on myofascial trigger points (MTrPs) in individuals with symptomatic hallux valgus (SHV). Methods: A total of 30 female volunteers, aged 25-60, with hallux valgus (HV) were randomly divided into two groups: DN group (n = 15) and control group (n = 15) who received sham dry needling. The outcome measures were pain intensity (Visual Analogue Scale, VAS), Foot Function Index (FFI), hallux valgus angle (HVA), and first metatarsophalangeal joint radiography. Results: At the end of the intervention, the HVA showed a significant decrease in the case group (P < 0.001); however, statistically no significant difference was found in the pain intensity and foot function between the two groups (P > 0.05). These findings were maintained for a week and a month during follow-ups. Conclusion: According to the findings, dry needling can be recommended for improving first metatarsophalangeal joint alignment in the mild to moderate SHV individuals. (C) 2020 Elsevier Ltd.
