“…However, it has been shown that they do not have any advantage over high basketball shoes. 8 Intrinsic conditions associated with recurrent ankle sprain may be congenital, such as tarsal coalition 9 and hyperlaxity of joints. 10 It was found that military recruits had more ankle sprains if the body mass moment of inertia was high and if they had a history of sprain.…”

Objectives: To examine changes in the pattern of force transfer between the foot and the floor associated with chronically sprained ankles by measuring the peak forces and their timing under several regions of the feet during level walking. Methods: Twelve young male subjects (mean (SD) age 21 (2) years) with recurrent ankle sprains were studied. Seven of them had unilateral and bilateral chronic instability and laxity, and five had bilateral instability. Twelve healthy men (without orthopaedic or medical disease) served as a control group. Subjects walked at their own pace along a 7 m walkway, which included a Mini-EMED pressure distribution measuring system. The variables measured were relative peak force (fraction of body weight) and relative timing (fraction of stance time). These variables were measured under six regions of interest in each foot print: heel, midfoot, medial, central, and lateral forefoot, and toes. Results: (a) A significant delay to the time of peak force under the central and lateral forefoot and toes in subjects with chronic ankle instability. (b) A significant decrease in the relative forces under the heel and toes and an increase in the relative forces under the midfoot and lateral forefoot in subjects with chronic ankle instability. (c) In the patients with unilateral instability, there were no significant differences in any of the variables between the injured and non-injured foot. Conclusions: In patients with chronic ankle instability, there is a slowing down of weight transfer from heel strike to toe off, a reduced impact at the beginning and end of the stance phase, and a lateral shift of body weight.A nkle sprain is the most common injury in athletes and people participating in sport, representing 15-20% of all sport injuries.1 In soccer and basketball, the risk of ankle sprain is even higher, being 45% and 31% respectively.

“…The clinical presentation of subtalar joint coalition may vary from painful pes planus to hindfoot pain or recurrent ankle sprains. There is evidence that the presence of a tarsal coalition can increase the incidence of ankle sprains in athletes [3]. Depending on their activity levels or the severity of their coalition, affected patients can present from early childhood to mid adulthood.…”

“…Clinical manifestations are also less severe: spastic flatfoot may be evident, although the condition is commonly asymptomatic. This coalition may predispose to ankle sprain (3,18). Fracture of an osseous calcaneonavicular bridge has also been reported (6).…”
