BACKGROUND Although footwear has been linked to falls in older people, it remains unclear as to which shoe features are beneficial or detrimental to balance in older people. OBJECTIVE To systematically investigate how footwear features affect balance and stepping in older people. METHODS 29 community-dwelling people (mean (SD) age, 79.1 (3.7) years) undertook tests of postural sway, maximal...

We have reviewed the long-term results of 22 patients (23 fusions) with fractures of the os calcis, who had subtalar arthrodesis with correction of the deformity between 1975 and 1991. The mean follow-up was nine years (5 to 20). All patients were evaluated according to a modified foot score. A radiological assessment was used in which linear and angular variables were measured including the fi...

common yew (taxus baccata) is one of the native and extinguishing speices at northern forests of iran that is very important as a genetic reserve and, therefore, more studies are necessary for preservation and restoration of this rare forest speices. for having high value and complete preservation of gene structure, vegetative propagation is one of the suitable in use methods in this field. thi...

OBJECTIVE Identify the biological, social, and economic conditions influencing the knee height/stature index (KHSI) in growing individuals of Maya ancestry in the city of Merida, Yucatan, Mexico. METHODS The hypothesis was that KHSI values would be lower in subjects with two Maya surnames. This was tested by analyzing the effect of a series of environmental, biological, and socioeconomic vari...

The purpose of this investigation was to study the effect of elevating the heel during unilateral weight-bearing on structure of the foot, especially a “flat” foot, and on function of the foot in maintaining balance. We examined 16 healthy women, 21 to 23 years of age, who stood unilaterally on the right foot with the heel elevated 0, 5, 10, 15, 20, 25, 30, and 40 mm. We measured height of the ...

Gait kinematics have been shown to vary with speed and visual-target fixation distance, but their combined effects on toe trajectory during treadmill walking are not known. The purpose of this investigation was to determine the role of walking speed and target distance on vertical toe trajectory during treadmill walking. Subjects walked on a treadmill at five speeds while performing a dynamic v...
