BackgroundThis study aimed at estimating the extent to which a combination therapy of extracorporeal shockwave therapy (ESWT) with usual care (exercise and orthotic support) improve functional ability in the patient with plantar fasciitis when compared to usual care alone.MethodsParticipants with plantar fasciitis were randomly allocated into two groups: ESWT (n=23), and control (n=21). All participants received home exercise program with orthotic support. In addition, ESWT group received 2000 shock waves with 0.02 mJ/mm2 for three sessions. Functional outcomes were measured by function subscale of American orthopedic foot and ankle society (AOFAS-F) score and 12 minutes walking test including walking speed, cadence. The scores were recorded at baseline, third week and third month after the treatment. Analysis was performed using repeated measures ANOVA, and an intention to treat approach using multiple imputations.ResultsResults showed that there was a significant improvement in AOFAS-F total score and walking speed over three months in both groups (p<0.001, p=0.04 respectively); improvements in AOFAS-F were particularly in activity limitation (p=0.001), walking distance (p=0.02) and walking surface (p=0.02). Groups were comparable with each other for both walking speed and AOFAS-F in any assessment time (p>0.05). However, groups performed differently in cadence where there was an increase in cadence in ESWT group whereas a decline in control at the third month (p=0.07).ConclusionThe results revealed that ESWT did not have an additive benefit over usual care to improve foot function and walking performance in patient with plantar fasciitis over three months post-treatment.Copyright © 2020 Elsevier Ltd.
