The plantar fascia is a dense, fibrous band that serves essential functions in foot stability and protecting the delicate nerves and vessels on the underside of the foot. Originating from the medial calcaneal tubercle, located at the bottom of the heel just before the arch, it extends and attaches to all five toes.

During the gait cycle, the plantar fascia plays a crucial role in foot stabilization. It provides necessary flexibility during heel strike to accommodate uneven surfaces. As weight shifts to the forefoot and the heel lifts, the plantar fascia shortens, acting as a rigid lever to propel forward movement.

Plantar fasciitis, a common condition, occurs when repetitive strain exceeds the tissue’s threshold. The primary cause of plantar fasciitis is fallen arches, often referred to as “flat feet.” Individuals with plantar fasciitis commonly experience tightness in their calf muscles, placing additional strain on the fascia.

Research has established a strong connection between calf muscle tightness and the severity of plantar fasciitis symptoms. When the calf muscles are excessively tight, they limit ankle dorsiflexion (moving the toes towards the shin). Consequently, the plantar fascia compensates for the restricted motion, leading to excessive stretching and strain on the band.

At Crux Sport & Spine, our St. George chiropractors focus on improving foot, ankle, and hip function to enhance range of motion and strengthen vulnerable areas. Through targeted exercises and mobilization of the ankle joint, we work towards restoring stability, enabling you to step on your foot with reduced pain and discomfort.
