50 patients with plantar fasciitis were randomized to receive manual therapy and standard treatment, or standard treatment alone. The purpose of this study was to investigate the impact of manual therapy, specifically ankle, subtalar, and midfoot joint mobilization, on dorsiflexion, and its association with improvement in pain (numeric pain-rating scale [NPRS]) and functional (Lower Extremity Functional Scale [LEFS]). Outcomes were measured after 2 weeks of treatment, 4 weeks of treatment (ie. end of treatment), and at 6-week follow-up. Results from the study showed no significant difference between groups for pain, functionality, or dorsiflexion over the course of the study. Both groups demonstrated improved pain and functionality by completion of the study.
