Excellent ICC values were observed in the adapted core stability test for inter-tester reliability (0.97) and good to excellent intra- tester reliability (0.73-0.90).
The intraclass correlation coefficients (ICC) and 95% Confidence Intervals (CI) were computed to establish inter-tester and intra- tester reliability.
Fifteen physically active male subjects (19.46 ± 0.63) free from any orthopaedic or neurological disorders were recruited from a convenience sample of collegiate students. To establish the inter-tester and intra- tester reliability of this adapted core stability test. To adapt the trunk stability test to facilitate further sub-classification of higher levels of core stability in athletes for use as a screening tool. O'Connor, S McCaffrey, N Whyte, E Moran, K The development and reliability of a simple field based screening tool to assess core stability in athletes. This procedure is therefore perfectly suited for the evaluation and monitoring of strong athletes with hip, groin and hamstring injuries, some of the most common and troublesome injuries in sports. The present study shows that isometric hip- and knee-strength measurements have acceptable inter-tester reliability at the group level, when testing strong individuals, using HHD with belt-fixation. Furthermore, standard errors of measurement in per cent (SEM %) ranged from 5 to 11 %, and minimal detectable change in per cent (MDC %) from 14 to 29 % for the different hip and knee actions. The intra-class correlation coefficients (ICC 2.1) ranged from 0.76 to 0.95. No systematic between- tester differences (bias) were observed for any of the hip or knee actions. The tester-order and hip-action order were randomised. Isometric hip abduction, adduction, flexion, extension, and knee-flexion strength were tested. Two physiotherapy students (1 female and 1 male) performed all the measurements after careful instruction and procedure training. Twenty-one healthy athletes (6 women), 30 (8.6) (mean (SD)) years of age, were included. The aim of the present study was therefore to examine the inter-tester reliability concerning strength assessments of isometric hip abduction, adduction, flexion, extension and knee-flexion strength, using HHD with external belt-fixation. Belt-fixation of the dynamometer may resolve this. However, systematic bias exists when testers of different sex and strength perform the measurements. In football, ice-hockey, and track and field, injuries have been predicted, and hip- and knee-strength deficits quantified using hand-held dynamometry (HHD).
Thorborg, Kristian Bandholm, Thomas Hölmich, Per Hip- and knee-strength assessments using a hand-held dynamometer with external belt-fixation are inter-tester reliable. VR appears to provide a reliable and more ecologically valid method of cervical motion evaluation than previous conventional methodologies. The results suggest high reliability for peak and mean velocity as measured by the interactive Neck VR assessment of neck motion kinematics. Minimal detectable change for peak velocity ranged from 41 to 53 °/s, while mean velocity ranged from 20 to 25 °/s. Mean velocity had a good global reliability (0.84), except for left rotation directed movement with moderate reliability (0.68). High reliability was shown for peak velocity globally (0.93), in left rotation (0.9), right rotation and extension (0.88), and flexion (0.86). Good reliability was found of neck motion kinematic measures in flexion, extension, and rotation (0.64-0.93 inter-class correlation). Each participant was tested twice by two different testers. The objective of the interactive assessment was to hit 16 targets, randomly appearing in four directions, as fast as possible. This reliability study included 46 asymptomatic participants, who were assessed using the neck VR system which displayed an interactive VR scenario via a head-mounted device, controlled by neck movements. Therefore, the purpose of this study was to establish inter-tester reliability of neck kinematic measures so that it can be used as a reliable assessment and treatment tool between clinicians. Neck VR enables analysis of task-oriented neck movement by stimulating responsive movements to external stimuli. The use of virtual reality (VR) for assessment and intervention of neck pain has previously been used and shown reliable for cervical range of motion measures.
