Efficacy of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis: a systematic review and meta-analysis

Abstract

ObjectiveTo investigate the effects of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis.DesignSystematic review of randomised controlled trials (RCTs).Data sourcesAMED, MEDLINE, PEDro, Cochrane, SPORTDiscus, CINAHL, EMBASE and PsycINFO without language or date restrictions up to 3 February 2023.Eligibility criteriaRCTs that evaluated the efficacy of any pharmacological and non-pharmacological therapies compared with control (placebo, sham, waiting list or no intervention) on pain intensity and disability in people with plantar fasciitis. Two reviewers independently screened eligible trials, extracted data, assessed the methodological quality of included trials and assessed the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations framework. Mean differences (MDs) with 95% CIs were reported.ResultsSeventeen different therapies investigated in 28 trials were included in the quantitative analysis. For non-pharmacological therapies, moderate certainty evidence showed short-term effects of customised orthoses on pain intensity when compared with control (MD of −12.0 points (95% CI −17.1 to −7.0) on a 0–100 scale). Low certainty evidence showed short-term effects of taping on pain intensity (−21.3 (95% CI −38.6 to −4.0)). Long-term effects and effects on disability are still uncertain. For pharmacological therapies, low to very low quality evidence from few trials with small samples was inconclusive and supports that high-quality trials are needed.ConclusionsModerate-quality and low-quality evidence demonstrates customised orthoses and taping, respectively, reduce pain intensity in the short term in patients with plantar fasciitis.PROSPERO registration numberCRD42021224416.
