Assessment of the reliability of real time ultrasound scanning to measure the humeral head position in a number of glenohumeral joint positions

Abstract The aim of the current study is to assess the intra-rater and inter-rater reliability of real time ultrasound scanning in measuring static humeral head position. Real time ultrasound scanning, an experimental clinical

Quantitative Assessment of Glenohumeral Translation in Professional Golfers Using Ultrasound

Quantitative Assessment of Glenohumeral Translation in Professional Golfers Using Ultrasound Posterior hyper laxity of the glenohumeral joint could contribute to shoulder problems in golfers; hence, a measuring tool to quantify glenohumeral laxity clinically is important. Objective: Assess within-session intra-rater reliability of using Ultrasound to measure glenohumeral laxity, and quantify glenohumeral joint translation in symptom free elite golfers and non overhead athlete controls. Study design: Descriptive laboratory study. Ultrasound Scanning measured humeral head translation during the Drawer test in 30 asymptomatic professional golfers recruited on the PGA European Challenge Tour, and 10, asymptomatic, non overhead male athlete controls, all male and under the age of 40 years. Within-session intra-rater reliability coefficients (Intraclass correlation ICC3.1) were moderate to good, with scores of more than 0.75 (95% confidence interval 0.51-0.94) for the technique and instrumentation used. Posterior translation of the humeral head was 1.29 mm greater in golfers in the non dominant/lead shoulder compared with controls. This was statistically significant when p=0.01(Mann-Whitney U test). Conclusion: Real Time Ultrasound Scanning is a reliable method of assessing posterior glenohumeral laxity in golfers. Posterior translation of the humeral head was greater in golfers in the non dominant/lead shoulder compared with controls.

A 3D assessment and feedback tool for Ankylosing Spondylitis from the perspective of healthcare professionals

ABSTRACT To investigate the utility of 3D visualization technology to augment assessment and feedback for Ankylosing Spondylitis (AS), a visualization prototype was developed, and both subjective and objective measures of current assessment instruments were compared. To verify and establish a base-line for the prototype’s effectiveness, motion data and measurement data from a healthy adult in a laboratory environment were collected. To validate the prototype, a qualitative evaluation was undertaken using multiple methods including a pilot study, focus groups, and individual interviews. Research subjects comprised physiotherapists in clinical practice and academia and content analysis of their responses was used to substantiate the findings. The prototype enhanced both assessment and feedback of AS from the physiotherapist’s perspective and they believed it to be superior to the current methods used in practice for assessing the condition and in documenting variations for subsequent treatment. The physiotherapists believed that such a system had potential to encourage multidisciplinary working, and to be patient-centric, both with respect to the process of treatment and with regard to the convenience it offered to patients in managing their own condition. 3D visualization of AS symptoms and its treatment via exercise is a valuable technique as demonstrated by the prototype system.
