Plantar pressure distribution during gait in athletes with functional instability of the ankle joint: preliminary report

Alterations in evertor/invertor muscle activation and center of pressure trajectory in participants with functional ankle instability

“…Increased invertor activation coupled with decreased evertor activation could result in a more supinated foot position during the stance phase of movement in patients with ankle instability. This idea is consistent with reports of laterally-deviated plantar pressures during the stance phase of gait in patients with ankle instability (Nawata et al, 2005;Nyska et al, 2003).…”

Spatial postural control alterations with chronic ankle instability

“…Because of the associated motions that occur with supination; calcaneal inversion, talar abduction and dorsiflexion, the ankle is put into a more rigid, closed packed position. Previous research assessing plantar pressure differences between CAI and controls has shown that CAI patients spend a longer portion of their stance phase of gait on the lateral aspect of the foot as compared to healthy controls [9]. These results appear to demonstrate that during stance phase, the CAI group may exhibit a more supinated foot posture compared to controls.…”

“…Kinetic alterations such as a more lateral plantar pressure distribution during the stance phase of gait have been reported in people with CAI [9,10]. However, to our knowledge, no research has been conducted to determine if there are spatial differences in the plantar surface location of the COP or TTB minima data points between CAI and healthy groups during single limb standing.…”

Experimental Study on Different Characteristics of Plantar Pressure Distribution in Different Sports Shoes

“…So far, many scholars have studied how to design sports shoes to improve their cushioning and health care effects. Nawata et al analyzed the plantar pressure of 70 students during exercise [5]; Sacco et al analyzed the effects of different types of shoes on the leg muscles and plantar pressure [4]; Mika et al studied the influence of high heels on the spines and plantar arch of women during gait [6]; Nagel and Van et al studied how to modify the structure of shoes to reduce the pressure in forefoot [7][8]; De et al studied the changes in plantar pressure during running on bare foot and in shoes [9]; Henning et al studied the difference in plantar pressure in different kinds of sports shoes [10]. At the same time, some scholars also designed healthcare shoes that could help people lose weight, correct posture, reduce injuries during gait and lower plantar loads [11][12][13][14][15][16][17].…”
