Background:
Pulsed electromagnetic field (PEMF) therapy is a conservative, noninvasive, nonpharmacological option for treatment of plantar fasciitis that accelerates the body's anti-inflammatory and healing responses.
Methods:
In this case series, adult patients presenting with more than 2 weeks of heel pain due to plantar fasciitis were treated with the OrthoCor Active System (OrthoCor Medical Inc, Blaine MN) PEMF device for 12 weeks. Efficacy was measured at 0 (baseline), 4, 8, and 12 weeks of treatment. Ultrasound was used to measure plantar fascia maximal thickness and hypoechoic region width. Function was evaluated using Foot and Ankle Disability Index (FADI) and Patient Specific Functional Scale (PSFS) survey scores.
Results:
Repeated measures ANOVA showed a statistically significant improvement in all assessments with PEMF therapy. The mean plantar fascia thickness decreased by 34%, the mean hypoechoic region width decreased by 79%, the mean FADI score improved by 46%, and the mean PSFS score improved by 166%. Compared to historical control data from other studies, PEMF and stretching therapy reduced plantar fascia thickness by 34% compared to 16% for dexamethasone injection and 6% for placebo saline injection; FADI improved by 46% after 12 weeks of PEMF compared to 43% after 1 year of treatment with indomethacin, heat and shoe pads, plantar facia stretching, or calf stretching; and PSFS improved by 166% with PEMF compared to 96% after primal reflex release treatment.
Conclusion:
Pulsed Electromagnetic Field (PEMF) therapy was effective for stimulating healing and improving function for patients with plantar fasciitis, demonstrated by significant improvement in ultrasound measures and functional scores. This study suggests that PEMF therapy is an effective conservative, nonpharmacologic treatment option for plantar fasciitis.
