The efficacy and safety of extracorporeal shock wave therapy (ESWT) on chronic plantar fasciitis (PF) in patients with axial spondyloarthritis (axSpA) remain unclear. To investigate the efficacy and tolerability of ESWT in patients with PF in axSpA. In this double-blind, randomized controlled trial, 22 axSpA patients with PF who had heel pain above 5 according to visual analog scale (VAS) over 3 months were randomly divided into 2 groups: ESWT and sham-ESWT. Both groups received a total of three treatments at 1-week intervals. All patients were assessed by the VAS, heel pressure algometry, Foot Function Index (FFI), and plantar fascia ultrasonography (thickness and morphology) at baseline, 1 week after each session, 4th and 8th week after the last therapy. The mean ± SD ages of the ESWT and sham-ESWT groups were 43.8 ± 8.2 and 48.5 ± 7.6 years, respectively. Significant time effects between the time points were observed in both groups in terms of VAS, pressure algometry, and FFI. There was a statistically significant decrease in pain, an increase in perceived pressure algometry values, and an improvement in activity restriction in the ESWT group compared to the sham-ESWT group. There was not a change in the plantar fascia thickness before and after the intervention in both groups. No side effects were observed during the treatment and follow-up. ESWT appears to be a safe and well-tolerated physical therapy modality for improving chronic refractory heel pain due to PF in patients with axSPA. This trial was registered to The Australian New Zealand clinical trial with the registration number
ACTRN12618001954213.
