“…[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.…”

“…A later study by the same authors examined participant hits on the device and detected extremely high reliability of their Simple, Moderate, and Complex protocols indicating reliable testing procedures. 9 Unlike the previous literature, this study was unique in that the novel protocols built on one another and gradually increased in cognitive demand. Although previous literature has also used protocols with dual tasks, this study introduced the different protocols at varying time points.…”

“…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. 9 With moderate reliability detected at past time points, we would expect that this study's different time points and novel protocols would have similar reliability.…”

“…This time frame was selected to decrease the likelihood of a carryover effect of learning tasks from the first 2 sessions, therein reducing the potential for training effects. 9,14 In addition, this delay expands possible assessment time frames and clinical relevance. Participants were positioned in similar proximity to the board and reminded of protocol directions.…”

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...

In CLN3 disease, impairments in motor function are frequently reported to have later onset compared to visual and cognitive decline, but upper limb motor function has yet to be explored in this population. In a cohort of 22 individuals with CLN3, we used a novel application of multiple measures to (1) characterize motor function, particularly of the upper limbs, in activities of daily living (ADLs), and (2) explore associations between motor function and age as well as visual ability, disease severity, and cognitive function, as evaluated by the Unified Batten Disease Rating Scale (UBDRS), a validated CLN3 disease measure. ADLs that required coordination, speed, and fine motor control were particularly challenging for children with CLN3 based on item‐level performance across direct assessments (Jebsen–Taylor Hand Function Test [JTHFT] and MyoSet Tools) and caregiver reports (Pediatric Evaluation of Disability Inventory‐Computer Adaptive Testing [PEDI‐CAT] and Patient‐Reported Outcomes Measurement Information System [PROMIS] Pediatric Upper Extremity). Poorer visual ability, disease severity, and cognitive function were associated with worse performance on these measures, whereas age had limited impact. These findings support the need for children with CLN3 to receive skilled clinical evaluation and treatment tailored to their individual needs, particularly in the context of ADLs, as their symptom profile progresses.

Test-Retest Reliability of Three Dynavision Tasks

Abstract: The test-retest reliability of three Dynavision tasks of graded difficulty was estimated as high, with intraclass R correlation coefficients ranging from .88 to .97, and paired correlation coefficients ranging from .74 to .92. Recommendations are made for reliable testing procedures.
