Abstract

Background:Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia supports the longitudinal arch and absorbs ground reaction forces during the static and dynamic phase(s) of weight-bearing. The purpose of this randomized controlled trial study was to determine the effects of CAD/CAM foot orthoses that were designed based on the dynamic plantar pressure in patients with plantar fasciitis.Methods:This study was performed on 34 patients with plantar fasciitis. Outcomes were compared based on plantar fascia thickness; peak pressure, mean pressure, and maximum force; and pain, activity of daily living, quality of life, and sports activity that were evaluated by ultrasound, plantar pressure platform, and the Foot and Ankle Outcome Score, respectively. The patients were randomly assigned into two groups: the experimental group (CAD/CAM orthoses and night splint) and the control group (night splint only). All data were recorded again after 4 weeks.Results:Pain (P = 0.002) and plantar fascia thickness (P = 0.001) decreased significantly after 1 month of intervention. Activity of daily living (P = 0.044) and quality of life (P = 0.001) showed a significant increase. There was a trend in increasing peak pressure in all masking regions in both groups. The maximum force remarkably reduced in the experimental group in all regions.Conclusions:The results demonstrated that CAD/CAM foot orthoses designed based on dynamic plantar pressure with night splint can reduce the plantar fascia thickness and pain associated with plantar fasciitis and increase the activity of daily living, quality of life, and sports activity. © 2023 SAGE Publications Inc..
