The Impact of Extracorporeal Shock Wave Therapy and Dry Needling Combination on Pain and Functionality in the Patients Diagnosed with Plantar Fasciitis

Abstract

This study aimed to evaluate the efficiency of extracorporeal shock wave therapy (ESWT) and dry needling (DN) combination on pain and functionality in plantar fasciitis. Forty patients who were clinically diagnosed with plantar fasciitis were included in the study. The patients were randomly divided into 2 groups. The ESWT-DN group was applied 3 sessions of ESWT to plantar fascia and DN to the trigger points in the gastrosoleus muscles. The ESWT group was applied only ESWT treatment to plantar fascia. We used visual analog scale (VAS) for pain and a pressure algometer for pressure pain threshold. The functionality of the patients was evaluated with Foot Function Index (FFI). Also, maximum painless standing time and maximum painless walking distance were recorded. All assessments were repeated twice; first, pretreatment and second 1 month after the treatment. In both groups, there were statistically significant improvements in VAS, pressure pain threshold, maximum painless standing time, maximum painless walking distance, and FFI's pain, disability, and activity limitation subscales scores (p ≤ .001). In intergroup comparison; it was showed that VAS scores, maximum painless standing time (p = .002), maximum painless walking distance (p ≤ .001), and FFI pain subscale scores (p = .034) were statistically superior in the ESWT-DN group. There was no statistically difference between the groups in pressure pain threshold (p = .132), FFI disability (p = .081), and FFI activity limitation subscale (p = .226) scores. ESWT and DN combination therapy in plantar fasciitis was seen to be superior in the pain scores. Further studies with larger patients' groups and longer term results of this combination are needed for a better comparison.
