Table 5 Overview of reliability, validity and measurement error for other motor assessments used to monitor movement changes following a concussion
| Â | Time taken | Equipment | Test procedure | Outcome variable | Reliability | Validity | Measurement error | Optimal conditions |
|---|---|---|---|---|---|---|---|---|
Non-instrumented task specific assessment | ||||||||
Run-roll-aim | ||||||||
[41] | 10–20-min | NA | 4 trials, military course with combat specific tasks including roll and aim | Time to complete, number of errors | Inter-tester: r = 0.28–0.89 | Between-group differences: p =  < 0.01 | – | Military specific |
Portable warrior test of tactile agility | ||||||||
[96] | 10–20-min | Stopwatch | 5 trials, military course with combat specific tasks including run, roll, and backwards run. Performed under single task and dual-task conditions | Time to complete, number of errors | – | Between-group differences single-task: p =  < 0.001 Between-group differences dual-task: p = 0.004 | – | Military specific |
Instrumented task specific assessment | ||||||||
Instrumented portable warrior test of tactile agility | ||||||||
[49] | 10–20-min | IMU | 5 trials, military course with combat specific tasks including run, roll, and backwards run. Performed under single task and dual-task conditions | Time to complete, number of errors, COM or COP displacement | – | AUC of ‘lowering and rolling’ movements: AUC = 0.83 Between-group differences: 0.08–< 0.0001 | – | Military specific |
