As per available reports about 100 journals, 200 Conferences, 30 workshops are presently dedicated exclusively to Foot and ankle and about 366282 articles are being published on the current trends in Foot and ankle. In terms of research annually, USA, India, Japan, Brazil and Canada are some of the leading countries where maximum studies related to Foot and ankle are being carried out. As reported in “Correlates of foot pain severity in adults with hallux valgus: a cross-sectional study” article, Hallux valgus (HV) is highly prevalent and associated with progressive first metatarsophalangeal joint subluxation and osteoarthritis. The link between structural HV deformity and foot pain is unclear. This study investigated possible explanatory factors surrounding foot pain in HV, including radiographic HV angle and signs of joint degenerationHere we focus on the difference between heel striking and forefoot striking (see bottom of page for more on midfoot striking which is often intermediate). In heel striking, the collision of the heel with the ground generates a significant impact transient, a nearly instantaneous, large force. This force sends a shock wave up through the body via the skeletal system. In forefoot striking, the collision of the forefoot with the ground generates a very minimal impact force with no impact transient. Therefore, quite simply, a runner can avoid experiencing the large impact force by forefoot striking properly. The explanations below illustrate how and why a large collision is generated when heel striking and why such a small collision is generated when forefoot striking.
