Reliability of 5 Novel Reaction Time and Cognitive Load Protocols
Journal of Sport Rehabilitation
|May 30, 2018
Summary
This study found that novel reaction time (RT) protocols using the Dynavision D2® system are reliable for athletes returning to play, with consistent results at 1-hour and 14-day intervals.
Area of Science:
- Sports Medicine
- Neuroscience
- Human Performance
Background:
- Reaction time (RT) is critical for athletic performance and safe return to play after injury.
- The Dynavision D2® system offers a tool for assessing and rehabilitating RT under cognitive load.
- Previous research established reliability for simple RT protocols within 24-48 hours.
Purpose of the Study:
- To assess the test-retest reliability of five new RT protocols with varying cognitive demands.
- To determine the reliability of these protocols across different time intervals.
Main Methods:
- Thirty healthy participants completed three testing sessions.
- Sessions were spaced 1 hour apart, and then approximately 14 days apart.
- Participants performed five novel RT protocols on the Dynavision D2® system, increasing in cognitive load.
Main Results:
- All five RT protocols demonstrated good to excellent reliability (ICC .75-.90) across all test-retest intervals.
- No significant differences in RT were observed between the testing sessions.
Conclusions:
- The novel RT protocols are reliable for clinical assessment at both 1-hour and 14-day intervals.
- These findings expand the established reliable assessment windows for RT.
- The study introduces innovative protocols that effectively challenge cognitive function.

01:29Reliability and Validity
14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Hess’s law can be used to determine the enthalpy change of any reaction if the corresponding enthalpies of formation of the reactants and products are available. The main reaction may be divided into stepwise reactions : (i) decompositions of the reactants into their component elements, for which the enthalpy changes are proportional to the negative of the enthalpies of formation of the reactants, −ΔHf°(reactants), followed by (ii) re-combinations of the elements (obtained in step 1) to...

02:53Determining Order of Reaction
62.4K
Rate laws describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In a rate law, the rate constant k and the reaction orders are determined experimentally by observing how the rate of reaction changes as the concentrations of the reactants are changed. A common experimental approach to the determination of rate laws is the method of initial rates. This method involves measuring reaction rates for multiple experimental trials carried out using...
