It has long been accepted that plantar fascia supports medial longitudinal arch both in weight bearing and locomotion. Literatures were reviewed through a systematic method. First, current knowledge about plantar fascia properties were established and analyzed; second, previous studies and methods to study plantar fascia were analyzed; finally, the problems in previous researches to study plantar fascia were argued. It was found that plantar fascia affects foot arch and foot adaptation under vertical load in living individual. In accordance with results of this literature review, the modification of plantar fascia thickness under vertical load is specific property of the plantar fascia in living individual. Additionally, the specific property of plantar fascia can help clinicians to diagnose the necessity of plantar fascia assessment along its length.展开更多

Direct measurement to monitoring the mechanical situation of plantar fascia at human locomotion is very difficult. The purpose of this study is to construct a three-dimensional finite element model of the foot to calculate the internal stress/strain value of plantar fascia during different stages of the gait. The simulated stress distribution of plantar fascia was the lowest at heel-strike,which concentrated on the medial side of calcaneal tubercle. The peak stress of plantar fascia was appeared at push-off,and the value was more than 5 times of the heel-strike position. Current FE model was able to explore the plantar fascia tension trend at the main subphases of the foot. More detailed fascia models and intrinsic muscle forces could be developed in the further study.展开更多

Four cases after individual releases of plantar fascia,spring ligament,long and short plantar ligaments were simulated respectively to compare their consequences to the predictions of the intact structure. It was founded that the foot arch didn't collapse obviously after any individual release of these structures. As plantar fascia was released,tensions of plantar ligaments were largely increased. Long and short plantar ligaments performed mutual compensation functions.展开更多
