Plantar fasciitis or plantar fascia pain makes up 10-15% of foot symptoms in adults (Tahririan et al., 2012); 8-10% in runners and 1% in of all referred orthopaedic patients.
The plantar fascia, also called the deep fascia of the sole, is triangularly shaped and stretches from the calcaneus to the toes. It is also responsible for accurate Windlass-mechanism, responsible for shock absorption in the foot during physical activity.
Injury is caused when overload causes collagen disruption of the plantar fascia and in some cases causes micro-tears to the tissue. Pain is exacerbated by weight bearing activities like running and jumping as the plantar fascia is stretched from the heel. It can often be more painful in the mornings.
Obesity also found as an aggravating mechanism, being found in 70% of all plantar fasciitis patients (Tahririan et al., 2012).
Analysis and modification of movement/running patterns; management includes mobilising the ankle joint and soft tissues, analysis of footwear and biomechanics. Physiotherapy: stretching and strengthening (high load training) of the lower limb, self myofascial release, proprioceptive and balance training for ankle stability;
