The Foot
-
Plantar heel pain is a common musculoskeletal foot disorder that can have a negative impact on activities of daily living and it is of multifactorial etiology. A variety of mechanical factors, which result in excessive load at the plantar fascia insertion, are thought to contribute to the onset of the condition. This review presents the evidence for associations between commonly assessed mechanical factors and plantar heel pain, which could guide management. ⋯ The evidence presented has been generated through studies with cross-sectional designs, therefore it is not known whether any of these associated factors have a causative relationship with plantar heel pain. Longitudinal studies are needed to ascertain whether the strength and flexibility impairments associated with plantar heel pain are a cause or consequence of the condition, as well as to establish activity thresholds that increase risk. Intervention approaches should consider strategies that improve strength and flexibility, as well as those that influence plantar fascia loading such as body weight reduction, orthoses and management of athletic and occupational workload.
