摘要

Introduction: The Assessment of Military Multitasking Performance (AMMP1) consists of six dualtask and multitask military-relevant performance-based assessments which were developed to provide assistance in making return-to-duty decisions after concussion or mild traumatic brain injury (mTBI.) The Run-Roll-Aim (RRA) task, one component of the AMMP, was developed to target vulnerabilities following mTBI including attention, visual function, dynamic stability, rapid transition, and vestibular function. One aim of this study was to assess the knowngroup and construct validity of the RRA, and additionally to further explore reliability limitations reported previously. Materials and Methods: A cross-sectional study consisting of 84 Active Duty service members in two groups (healthy control -HC and individuals experiencing persistent mTBI symptoms) completed neurocognitive tests and the RRA. The RRA task requires a high level of mobility and resembles military training activities in a maneuver that includes combat rolls, fast transitions, obstacle avoidance, and visual search. Observational and inertial sensor data were compared between groups and performance across four trial times was compared within groups. Correlations between RRA results and neurocognitive test scores were analyzed. Results: Simple observational measures (time, errors) did not differ between groups. Spectral power analysis of the inertial sensor data showed significant differences in motor performance between groups. Within group one-way ANOVAs showed that in HC trial 1, time was significantly different than trials 2,3 and 4 (F(3,47) = 4.60, p < 0.01, Tukey HSD p < 0.05) while the mTBI group showed no significant difference in time between trials. During testing individuals with mTBI were less likely to complete the multiple test trials or required additional rest between trials than HCs (chi(2) = 10.78, p < 0.01). Small but significant correlations were seen with two neurocognitive tests of attention and RRA performance time. Conclusion: While observational scores were not sensitive to group differences, inertial sensor data showed motor performance on the forward run, combat roll, and backward run differed significantly between groups. The RRA task appeared challenging and provoked symptoms in the mTBI group, causing 8 of 33 mTBI participants to stop the task or require additional rest between trials while none of the HC participants had to stop. Individuals with mTBI demonstrated slower learning of the complex motor sequence compared to HCs who had significant improvement after one trial of RRA. Complex novel training maneuvers like RRA may aid clinicians in informing return to duty decisions.
