BACKGROUND AND PURPOSE The purpose of this study was to determine the effects of different orthotic posting methods on controlling abnormal foot pronation during ambulation. SUBJECTS Twenty-two individuals with forefoot varus deformities of at least 8 degrees (13 women, aged 21-40 years, and 9 men, aged 20-50 years) participated in the study. The female(More)
This study was designed to examine the effect of varying degrees of imposed leg length difference on symmetry of the innominate bones in healthy college women with relatively equal leg lengths. Subjects' leg length was determined by clinical and roentgenographic procedures. Position of the innominate bones with and without lifts under one foot was measured(More)
Determination of innominate bone inclination in standing is frequently assessed in postural analysis of subjects. Currently, no goniometer for objective assessment of innominate bone inclination in standing is commercially available. The purpose of this study was to determine the intratester and intertester reliability and validity of measures taken with a(More)
Although techniques such as roentgenograms and magnetic resonance imaging can provide definitive information about leg length inequality, they are not easily implemented for screening purposes. Using relative heights of palpated iliac crests as criteria for determining degree of lateral pelvic tilt, we examined the immediate effect of simulating leg length(More)
STUDY DESIGN A within-subjects repeated measures design. OBJECTIVES To determine differences in the amount of vertical opening of the mandible among 3 different head positions. BACKGROUND Results from several studies have suggested that the position of the head and neck may affect temporomandibular joint function. Presently no standardized position of(More)
Experimental evidence supports the general conclusion that 6 or more weeks of immobilization will cause joint contractures due to changes in the capsules of animals whose limbs have been traumatized. There is controversy whether contractures will form in 6 weeks in limbs which are free of trauma. The purpose of this study was to determine if range of motion(More)
The sacroiliac joint (SIJ) is a possible source of low back pain or dysfunction. Various methods of visually assessing the relative position of the innominate to the sacrum have been used to evaluate SIJ dysfunction. The purpose of this special communication is to describe how a false-positive interpretation of innominate rotation may occur when a(More)
In this study we assessed the short-term effect of correcting leg length discrepancy on a vigorously performed task of resisted full body extension in 10 men, 18 to 35 years old, who had estimated leg length discrepancies of 10-15 mm. Using a cable ergometer we examined work performed, initial peak tension exerted on the ergometer, second peak tension, time(More)
