The Heel Pain-Plantar Fasciitis Guidelines link the International Classification of Functioning, Disability, and Health (ICF) body structures (Ligaments and fascia of ankle and foot, and Neural structures of lower leg) and the ICF body functions (Pain in lower limb, and Radiating pain in a segment or region) with the World Health Organization's(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)
BACKGROUND The Foot Posture Index (FPI) has been advocated as a simple and convenient tool to assess static foot posture in a clinical setting. Although published studies have indicated that the FPI has good intrarater reliability and moderate interrater reliability, these studies were conducted on a previous version of the tool that used eight criteria to(More)
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)
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)
BACKGROUND A study was conducted to determine the reliability and validity of a new foot mobility assessment method that utilizes digital images to measure the change in dorsal arch height measured at 50% of the length of the foot during the Sit-to-Stand test. METHODS Two hundred - seventy five healthy participants participated in the study. The medial(More)
Electrical stimulation of four specific acupuncture points (Liver 3, Stomach 36, Large Intestine 11, and the Groove for Lowering Blood Pressure) was examined in order to determine the effect of this stimulation on diastolic blood pressure in 10 subjects with diastolic hypertension. Subjects were randomly divided into two groups: (1) an Acu-ES group, which(More)
OBJECTIVE To compare gait and foot function between rheumatoid arthritis (RA) patients with painful pes planovalgus deformity and healthy age- and sex-matched adults. METHODS Gait analysis was undertaken in 23 RA patients (14 female and 9 male, mean age 52.3 years, mean disease duration 6.6 years) and 23 healthy adults (14 female and 9 male, mean age 49.5(More)
Conflicting results regarding local vascular response during cryotherapy have been reported in the literature. The purpose of this study was to determine whether application of a cold pack reduced blood volume in a nontraumatized ankle. Thirteen subjects ranging in age from 18 to 30 years (X = 22; SD = 3.9) participated in the study. An impedance(More)
The purpose of this study was to investigate whether the amount of ankle passive dorsiflexion range of motion influences the pattern of frontal plane rearfoot motion during walking. Three-dimensional motion of the rearfoot was measured in two groups of subjects, those with ankle passive dorsiflexion range of motion less than or equal to 10 degrees, and(More)
