Biomechanical Factors in Plantar Heel Pain and Their Clinical Relevance (running-physio.com)

• Reduced ankle dorsiflexion and limited great toe extension are key mechanical factors.
• Both pronated and supinated foot types can contribute to plantar heel pain.
• Calf tightness and weak intrinsic foot muscles increase plantar fascia strain.

"This article examines the mechanical factors contributing to plantar heel pain (PHP), including foot posture, ankle dorsiflexion range, calf flexibility, and intrinsic foot muscle function. It explains how altered foot biomechanics, such as excessive pronation or high arch, can increase strain on the plantar fascia. The importance of assessing these factors for tailored rehabilitation is highlighted. Practical implications for physiotherapy include targeted strengthening, stretching, and footwear modifications."
