- Plantar fasciitis is one of the most frequently occurring overuse injury of the foot and characterized by pain under the foot which aggravates during standing, walking and running. A frequently used treatment option for plantar fasciitis is the rocker shoe. The rocker shoe has a proximal apex position and a stiff insole. The rocker shoe is assumed to unload the plantar fascia during gait because it minimizes peak achilles tendon forces and dorsiflexion angles of the toes. However whether a proximal apex position and a stiff insole minimize the strain on the plantar fascia and how these two parameter interact has not been investigated yet. The current study aimed to establish the biomechanical effect of a proximal apex position and a stiff insole on the strain of the plantar fascia during gait? A musculoskeletal model similar to a previously published study and data from a cadaver study was used to estimate the strain of the plantar fascia in ten healthy young adults and nine patients diagnosed with plantar fasciitis. The participants walked for 60 seconds on their comfortable speed on a treadmill. Four different shoe conditions were randomly applied by varying sole stiffnes and the apex position of the shoe. Preliminary analysis of the acquired motion and force data indicates that a proximal apex position in combination with a stiff insole alone is insufficient in minimizing plantar fascia strain during gait. This will be the first study to show the biomechanical effects of a rocker shoe in a group of patients with plantar fasciitis. Our results have direct implications for the prescription of rocker shoes in the treatment of patients with plantar fasciitis.
