Effects of a good posture belt on buttock pressure during cross-legged sitting.

[Purpose] The purpose of the present study was to examine the effects of wearing a good posture belt on buttock pressure during cross-legged sitting. [Subjects] The study subjects were 34 adults who were divided into a good posture belt group (7 men, and 10 women) and a control group (7 men, and 10 women), with 17 subjects each. [Methods] Sensor mats were used to measure buttock pressure and changes in the total travel distance of the center of pressure, maximum pressure, and mean pressure.

Comparison of supraspinatus cross-sectional areas according to shoulder abduction angles.

[Purpose] The purpose of this study was to determine the changes in the supraspinatus cross-sectional areas according to shoulder abduction angles, using ultrasonography. [Subjects and Methods] The subjects consisted of 40 individuals (20 males and 20 females). The cross-sectional areas of the supraspinatus of all subjects were measured with ultrasonography at abduction angle of 0°, 30°, 60°, 90°, and 120°.

The effects of mouth opening on changes in the thickness of deep cervical flexors in normal adults.

[Purpose] The purpose of this study was to identify changes in the thickness of the deep cervical flexors (DCFs) according to the degree of mouth opening (MO) in normal adults. [Subjects] The study's subjects were 50 normal adults (30 men, 20 women). [Methods] Ultrasound was used to obtain images of muscles, and the NIH ImageJ software was used to measure the thickness of each muscle.

The effects of running in place on healthy adults' lumbar stability.

[Purpose] The purpose of this study was to examine the effects of running in place while using the abdominal drawing-in method on healthy adults' lumbar stability. [Subjects] A total of 30 subjects were divided into a training group of 15 subjects and a control group of 15 subjects. [Methods] The training group ran in place using the abdominal drawing-in method for 30 minutes per session, three sessions per week, for a total of six weeks.

Effects of pelvic adjustment on female university students' gait variables.

[Purpose] The purpose of this study was to examine the effects of pelvic adjustment using Gonstead techniques on posture in female university students. [Subjects] In this study, 30 female university students were selected and divided into a pelvic adjustment group of 15 subjects as an experimental group and a stretching group of 15 subjects as a control group. [Methods] Step length difference (SLD), stance phase difference (STPD), swing phase difference (SWPD), single support difference (SSD), and step time difference (STD) were evaluated in the subjects using an OptoGait.
