“…[7][8][9] Mean RTs in this study were also comparable with that of Wells et al 7 A preliminary study by Klavora et al 8 recorded and analyzed the number of hits the participants made during all protocols. These protocols were repeated on multiple occasions separated by 2-week intervals, much like our session 3.…”

“…With the shortest between-session duration of 48 hours, Wells et al 7 found intraclass correlation coefficient (ICC) values of .63 to .84 in recreationally active individuals. When separated by 2 weeks, Klavora et al 8 found moderate interclass reliability (.71 and .73) for each of the 2 protocols examined. Yet, an additional study investigated the test-retest reliability of 3 different protocols over a period of 8 weeks found excellent reliability (.88, .92, and .97) for all 3 protocols.…”

Context: Reaction time (RT) is crucial to athletic performance. Therefore, when returning athletes to play following injury, it is important to evaluate RT characteristics ensuring a safe return. The Dynavision D2® system may be utilized as an assessment and rehabilitation aid in the determination of RT under various levels of cognitive load. Previous research has demonstrated good reliability of simple protocols when assessed following a 24-to 48-hour test-retest window. Expanding reliable test-retest intervals may further refine novel RT protocols for use as a diagnostic and rehabilitation tool. Objective: To investigate the testretest reliability of a battery of 5 novel RT protocols at different time intervals. Design: Repeated measures/reliability. Setting: Interdisciplinary sports medicine research laboratory. Participants: Thirty healthy individuals. Methods: Participants completed a battery of protocols increasing in difficulty in terms of reaction speed requirement and cognitive load. Prior to testing, participants were provided 3 familiarization trials. All protocols required participants to hit as many lights as quickly as possible in 60 seconds. After completing the initial testing session (session 1), participants waited 1 hour before completing the second session (session 2). Approximately 2 weeks later (average 14 [4] d), the participants completed the same battery of tasks for the third session (session 3). Main Outcome Measures: The intraclass correlation coefficient, standard error of measurement, minimal detectable change, and repeated-measures analysis of variance were calculated for RT. Results: The intraclass correlation coefficient values for each of the 5 protocols illustrated good to excellent reliability between sessions 1, 2, and 3 (.75-.90). There were no significant differences across time points (F < 0.105, P > .05). Conclusions: The 1-hour and 14-day test-retest intervals are reliable for clinical assessment, expanding the time frames previously reported in the literature of when assessments can be completed reliably. This study provides novel protocols that challenge cognition in unique ways. Keywords: testing and measurement, clinical-evaluation, evaluationIn athletic situations, reaction time (RT), or the time it takes one to respond to a stimulus, 1 is crucial to an individual's ability to protect themselves from opponents and dangers of the sport. Previous research has found that athletes have faster RTs and movements compared with nonathletic individuals, potentially to avoid risk of game play such as player-to-player contact or to react quicker than opponents providing an advantage. 2,3 Therefore, when returning athletes to play following a concussion, it is important to evaluate RT characteristics to ensure a safe return to participation. RT is vital following concussion and is often impaired as a result of these injuries. 4 Postinjury standard of care typically involves complete cognitive and physical rest, although emerging evidence suggests more active management strategi...

“…Among them, the Dynavision TM , which shares some operational characteristics with the VISION COACH, has also been used by rehabilitation and human performance centers for occupational therapy and sport-related training (Klavora et al, 1994). In contrast to the VISION COACH, the main performance metric of Dynavision is the number of "hits" a participant can achieve on various Dynavision tasks (Klavora et al, 1995). Research has examined the test-retest reliability of the Dynavision tasks (Klavora et al, 1994(Klavora et al, , 1995 and investigated the relationship between Dynavision performance and various conventional psychomotor tests, such as the simple response time test (Vesia et al, 2008).…”

Test-Retest Reliability of the Dynavision Apparatus

Abstract: The test-retest reliability of two tasks on the Dynavision apparatus was estimated as moderate, with intraclass R correlation coefficients ranging from .71 (for .76 subjects) to .73 (for 41 subjects) and paired correlation coefficients ranging from 75 to 93.
