Table 3. Measure of Cognitive function.
| Reference | Tests used | Outcomes measured | Observation after intervention |
| Regterschot GR, et al., 2014 | 1. Stroop test (color-block test, color -word interference test, stroop difference test) 2. Digital span backward test |
1. Pyschomotor speed, selective attention and inhibition 2. verbal short memory/working memory |
No difference in results of color block test and Digital span backward test between WBV and control sessions. Performance on color -word interference test and stroop difference test improved after WBV. |
| Boerema AS et al., 2018 | 1. Stroop test (word test, color-block test, color -word test) 2. Digital Memory span forward and backward 3. Trail making test (part A and B) |
1.selective attention and inhibition 2. verbal short memory 3. cognitive flexibility |
Improvement in all tests except Trial making A test. Statistically significant improvement noted only in Stroop color word test. |
| Fuermaier AB, et al., 2014 | Stroop Color-Word Interference task (Color Block Test and the Color-Word Interference Test) | Selective attention and inhibition. | Significantly improved attention performance with small size (d = 0.44) in controls and a medium effect (d = 0.64) in individuals with ADHD. |
| Fereydounnia S et al., 2017 | 1. Visual choice reaction time test 2. Visual complex choice reaction time test 3. Auditory choice reaction time test 4. Anticipatory skill with high and low speed |
Reaction time and anticipatory skills | Improvement in all test parameters in both groups. Significant improvements in control group the auditory complex choice reaction time and anticipatory skill with high speed after vibration. In the lumbar hyper lordosis group, significant difference only in visual complex choice reaction time |
| Rosado, H et al., 2021 | Reaction time (simple and choice reaction), Cognitive timed up and go | Reaction time (simple and choice reaction), execution and psychomotor speed | Significant improvements in improvements in reaction time and dual-task performance (medium to large effect size). The interventions' effects were no longer evident after the 12-week no-intervention follow-up period |
| Paddan GS, 2012 | NASA-TLX subscales: Mental workload | Mental workload | 22.5° seat backrest angle adversely affect the psychomotor performance during vibration. 2–8 Hz, had a detrimental effect on both overall performance tracking and reaction times for the cognitive tasks |
| Amonette WE, 2015 | Computerized test battery (ImPACT) | Computerized test battery (ImPACT): verbal memory, visual memory, motor processing speed, and reaction time | No effect on visual or verbal memory, reaction time, or impulse control measured using ImPACT. Motor processing speed increased |
| Ki-Hong Kim, 2018 | K-MMSE, EEG | Orientation about time and space, memory, concentration and calculation, linguistic skills, understanding and judgment. Brain activation on EEG |
Significant improvement in all cognitive functions and EEG activation |
Attention deficit hyperactivity disorder (ADHD); NASA task load index (NASA-TLX); Immediate Post concussion Assessment and Cognitive Test (ImPACT); Korean-Mini-Mental Status Examination (K-MMSE), Electroencephalography (EEG)
