BACKGROUND the scoliometer was developed to analyze the axial rotation of the trunk in patients with idiopathic scoliosis. However, there is controversy regarding the reliability of the measures obtained with this device. OBJECTIVES to test the intra-rater and inter-rater reliability of the scoliometer in patients with scoliosis. METHODS 24 volunteers of both sex with idiopathic scoliosis d...

Background: Modern radiotherapy requires accurate contouring which may suffer in the postsurgical setting. We estimated post-prostatectomy interand intra-rater contouring reliability and assessed the effect on bladder and rectal normal tissue complication probability (NTCP). Methods: Four physicians each contoured two different treatment plans, separated by at least seven days, on 15 patients r...

The intra-rater reliability in rating essays is usually indexed by the inter-rater correlation. We suggest an alternative method for estimating intra-rater reliability, in the framework of classical test theory, by using the dis-attenuation formula for inter-test correlations. The validity of the method is demonstrated by extensive simulations, and by applying it to an empirical dataset. It is ...

PURPOSE To assess the intra- and inter-rater reliability of a standardized protocol for measuring proximal tibia and distal femur bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA). METHODS Ten able-bodied individuals (7 males) participated in this study. During one measurement session, the knee of each participant was scanned twice by rater 1 using DXA. Both scans were a...

[Purpose] The purpose of this study was to assess intra-rater and inter-rater reliability of musculoskeletal ultrasound (MSKUS) as a tool to measure supraspinatus tendon thickness in healthy subjects. [Subjects and Methods] Twenty healthy subjects were assessed in similar sitting position. Two experienced musculoskeletal ultrasound specialists measured supraspinatus tendon thickness. Tendon was...

BACKGROUND Considerable variability exists in clinical approaches to thoracolumbar fractures. Controversy in evaluation and nomenclature contribute to this confusion, with significant differences found between physicians, between different specialties, and in different geographic regions. A new classification system for thoracolumbar injuries, the Thoracolumbar Injury Severity Score (TLISS), wa...

The cross-sectional area (CSA) of the ulnar nerve is thought to be indicative of ulnar nerve entrapment. The purpose of the study was to determine reproducibility of ultrasonographic measurements of CSA of the ulnar nerve at the cubital tunnel in healthy adults. Two sonographers tested 69 participants using a standardized protocol. The inter-rater reliability intra-class correlation coefficient...
