The effectiveness of conservative, non-pharmacological treatment, of plantar heel pain: A systematic review with meta-analysis.

Plantar heel pain is one of the most common causes of pain and musculoskeletal pathologies of the foot. The aim of this systematic review was to identify the most effective, conservative and non-pharmacological treatments regarding pain in patients with plantar heel pain. The authors searched 5 databases and included only randomized control trials which investigated the efficacy of a conservative non-pharmacological treatment compared to the placebo, for the outcome of pain. Study selection, data collection and risk of bias assessment were conducted independently by two authors, and consensus was reached with a third author. Results were quantitatively summarized in meta-analyses, by separating homogeneous subgroups of trials by type of intervention. A total of 20 studies that investigated the efficacy of 9 different types of interventions were included, with a total of 4 meta-analyses carried out. The interventions: shock waves, laser therapy, orthoses, pulsed radiofrequency, dry-needling, and calcaneal taping resulted in being effective treatments for the outcome pain in patients with plantar heel pain when compared to the placebo. However, considering that the improvements were very small, and the quality of evidence was mostly low or moderate for many of the interventions, it was not possible to give definitive conclusions for clinical practice.
