The purpose of this study was to determine the relationship between the angle formed by the rearfoot when the subtalar joint is positioned in neutral and the pattern of rearfoot motion during walking. Each lower extremity for 50 healthy young adult subjects (mean age 25.5 years) was videotaped and the pattern of rearfoot motion was assessed using(More)
The purpose of this study was to determine the relationship of the static angle of the rearfoot during single leg standing, relaxed standing foot posture, and subtalar joint neutral position with the pattern of rearfoot motion during walking. The authors felt that this study was important to gain a better understanding of the relationship between dynamic(More)
The single-limb sway of 20 individuals with a history of unilateral inversion ankle sprain was compared to that of a control group of 30 individuals without a history of ankle sprain. Using a force platform to obtain center-of-pressure data, the linear distance traveled (mm) and the mean power frequency, (Hz) of postural sway were calculated for each(More)
This study presents research on typical movement of the rearfoot during walking. The data demonstrate the global nature of foot pronation and supination during gait. Study participants (N = 153) walked along a walkway while the angular displacement of the calcaneus, navicular, and first metatarsal relative to the tibia was measured; three-dimensional(More)
The purpose of this study was to first determine the intra-rater reliability of four different static measurement procedures used to assess first metatarsophalangeal joint extension range of motion and, second, determine which of the four static procedures provided a valid measure of the amount of first metatarsophalangeal joint extension required for(More)
Despite the fact that clinicians regularly perform static lower extremity measurements on their patients, to date, little research has been published supporting their ability to predict dynamic rearfoot motion. The abilities of static measurements to predict dynamic foot motion could have important implications considering the fact that excessive rearfoot(More)
Measurement of calcaneal inversion and eversion during walking is limited when subjects wear shoes. The authors of this study propose the use of transverse tibial rotation as a viable alternative measurement when barefoot assessment is not possible. The purpose of this study, therefore, was to: 1) determine the relationship between transverse tibial(More)
Twelve subjects between the ages of 24 and 35 years walked barefoot over a pressure platform with the following insole materials placed directly on top of the platform: 1) PPT, 2) Spenco, and 3) Viscolas. Maximum vertical force, vertical force-time integral as well as maximum plantar pressure data were collected for the rearfoot, midfoot, and forefoot(More)
BACKGROUND A study was conducted to determine the reliability and minimal detectable change for a new composite measure of the vertical and medial-lateral mobility of the midfoot called the foot mobility magnitude. METHODS Three hundred and forty-five healthy participants volunteered to take part in the study. The change in dorsal arch height between(More)
The purpose of this study was to determine the pattern and magnitude of navicular bone (NB) movement during walking as well as the relationship between dynamic NB and rearfoot movement. The angle of rearfoot and displacement of the NB was recorded in 106 subjects using the 6D Research electromagnetic tracking system. The relative change in the height of the(More)
