OBJECTIVE In an effort to limit exposure to ionizing radiation and fully characterize three dimensional changes in the spine of patients with scoliosis reliable non-invasive methods of spinal back contour analysis (Milwaukee Topographic Scanner) (MTS) have been developed. STUDY DESIGN The current study compares spinal topography measurements among different subject positions and evaluates the...

STUDY DESIGN Prospective study. PURPOSE To evaluate the reliability and validity of the adapted Korean version of the Quality of Life Questionnaire of the European Foundation for Osteoporosis (ECOS-16). OVERVIEW OF LITERATURE The validity of the Korean version of ECOS-16 has not been completely demonstrated. METHODS Translation/retranslation of the English version of ECOS-16, and full cro...

PURPOSE This preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain. METHODS Test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (ICC), standard error of measurements (SEMs), coefficient of variation (CV), and one-way repeated measures ANOVA using the va...

This study is based upon the premise that overall team performance is the sum of the team’s performance in several individual team processes. The purpose of this study was to develop a tool to measure performance in each of these individual team processes. This study begins the measurement development cycle by developing a tool that uses direct observation to collect data on team processes. The...

The non-linear dynamics of the chaotic 1D logistic map and its statistical and spectral properties are studied using MATLAB numerical simulations. We have developed an analog behavioral model and implemented logistic map on a field programmable analog array chip. Presented measurement results confirmed the chaotic behavior of the implemented system. Results show that field programmable analog a...

statement of problem: although different types of aesthetic brackets are introduced to orthodontic profession to reduce the complaints about the metallic braces, little studies have been done to assess patient's views regarding the attractiveness and acceptance of such brackets.   objectives: the goal of this study was to evaluate the perceived acceptability, beauty and value of different ortho...

A reliability study was conducted to determine (a) the intrarater and interrater reliability of goniometric measurement of active and passive wrist motions under clinical conditions and (b) the effect of a therapist's specialization on the reliability of measurement. Randomly paired therapists performed repeated measurements of active and passive wrist motions in 48 subjects who had been referr...

BACKGROUND This study evaluated the psychometric properties of the Non-communicating Children's Pain Checklist-Postoperative Version (NCCPC-PV) when used with children with severe intellectual disabilities. METHODS The caregivers of 24 children with severe intellectual disabilities (aged 3-19 yr) took part. Each child was observed by one of their caregivers and one of the researchers for 10 m...
