Intratester and Intertester Reliability during the Star Excursion Balance Tests

Abstract: 0bjective: To estimate intratester and intertester reliability and learning effects during the Star Excursion Balance Tests (SEBTs). Setting: A university athletic training research laboratory. Subjects: Sixteen healthy volunteers with no history of balance disorders or significant lower extremity joint pathology. Measurements: Length of excursion was measured manually for each trial. Results: ICCs for intratester reliability were .78–.96 on day 1 and 32–.96 on day 2. ICCs for intertester reliability were .35–.84 on day 1 and .81–.93 on day 2. Significant learning effects were identified for 4 of the 8 tests. Conclusions: Estimates of intratester and intertester reliability were high, but adequate practice trials should be performed before taking baseline measures.

Relationship between clinical and forceplate measures of postural stability

Abstract: Although sophisticated forceplate systems are available for postural stability analyses, their use is limited in many sports medicine settings because of budgetary constraints. The purpose of this investigation was to compare a clinical method of evaluating postural stability with a force-platform sway measure. Participants completed a battery of three stance variations (double, single, and tandem) on two different surfaces (firm and foam) while standing on a force platform. This arrangement allowed for simultaneous comparisons between forceplate sway measures and clinical assessments using the Balance Error Scoring System (BESS). Significant correlations were revealed for the single-leg and tandem stances on the firm surface and for double, single, and tandem stances on the foam surface. These results suggest that the BESS is a reliable method of assessing postural stability in the absence of computerized balance systems.

Center-of-pressure parameters used in the assessment of postural control

Abstract: Objective: To define the numerous center-of-pressure derivatives used in the assessment of postural control and discuss what value each might provide in the assessment of balance. Data Sources: MEDLINE and SPORTDiscus were searched with the terms balance, postural control, postural sway, and center of pressure. The remaining citations were collected from references of similar papers. A total of 67 references were studied. Conclusions: Understanding what is represented by each parameter used to assess postural control is crucial. At the present time the literature has failed to demonstrate how the variables reflect changes made by the postural-control system. Until it can be shown that the center of pressure and its derivatives actually reveal changes in the postural-control system, the value of using these measures to assess deficits in postural control is minimized.

Arthrogenic Muscle inhibition: A Limiting Factor in Joint Rehabilitation

Abstract: Objectives: To define the concept of arthrogenic muscle inhibition (AMI), to discuss its implications in the rehabilitation of joint injury, to discuss the neurophysiologic events that lead to AMI, to evaluate the methods available to measure AM1 and the models that might be implemented to examine AMI, and to review therapeutic interventions that might reduce AMI. Data Sources: The databases MEDLINE, SPORTDiscus, and CIHNAL were searched with the terms reflex inhibition, joint mechanoreceptor, Ib interneuron, Hoffmann reflex, effusion, and joint injury. The remaining citations were collected from references of similar papers. Conclusions: AMI is a limiting factor in the rehabilitation of joint injury. It results in atrophy and deficiencies in strength and increases the susceptibility to further injury. A therapeutic intervention that results in decreased inhibition, allowing for active exercise, would lead to faster and more complete recovery.

Assessing Reliability and Precision of Measurement: An Introduction to Intraclass Correlation and Standard Error of Measurement

Abstract: The reliability and precision of measurement in sports medicine are of concern in both research and clinical practice. The validity of conclusions drawn from a research project and the rationale for decisions made about the care of an injured athlete are directly related to the precision of measurement. Through analysis of variance, estimates of reliability and precision of measurement can be quantified. The purpose of this manuscript is to introduce the concepts of intraclass correlation as an estimate of reliability and standard error of measurement as an estimate of precision. The need for a standardized set of formulas for intraclass correlation is demonstrated, and it is urged that the standard error of measurement be included when estimates of reliability are reported. In addition, three examples are provided to illustrate important concepts and familiarize the reader with the process of calculating these estimates of reliability and precision of measurement.
