BACKGROUND: Students, as well as other professional drivers, must have focus to adequately perform their tasks. However, they are subjected to whole-body vibration (WBV) in their journey to school or work. OBJECTIVE: To investigate the influence of in-loco WBV exposure on focus, both instantaneously, as well as residually. Analysis is performed for both genders, as well as for the presence of Attention Deficit Hyperactivity Disorder (ADHD). METHODS: Using a tablet computer, 20 volunteers played a focus game available on an app for brain training while exposed or not exposed to WBV. The exposure was that of a car travelling on a stone paved route. The performance measure was the score provided at the end of each game. Subjective comfort and difficulty evaluations were also investigated. RESULTS: The results suggest that WBV had a negative effect on the focus performance. However, it proved positive three minutes after the exposure (residual effect). The mean scores of females were higher than for males for most of the tests, apart from the one under WBV although at the expense of getting more discomfort. The difficulty level was not different within the gender groups. CONCLUSION: It could be concluded that the group with ADHD had a small but positive influence on the results for most of the tests, indicating that they are less affected by the presence of WBV. Since many students and workers have ADHD, this may be considered an important finding. It was shown that objective results should not be the only measures to use, as the subjective evaluation may explain the results better.

Whole Body Vibration Training

OBJECTIVE: The aim of this study was to compare the effects of treadmill training (TT) and whole body vibration training (WBVT) on attention, severity of attention deficit hyperactivity disorder (ADHD) symptoms and impairment of executive function behaviors, and quality of life in children with ADHD. METHODS: Thirty children (7–11 years of age) with ADHD were randomly assigned to either the ‘TT’ group or the ‘WBVT in addition to TT’ group (TT + WBVT). Both groups received TT for 8 weeks (3 days/week). The TT + WBWT group also received WBVT for 15 minutes. Stroop Test TBAG form, Behavior Rating Inventory of Executive Function (BRIEF), Conners’ Rating Scale (CRS) and Pediatric Quality of Life Inventory (PedsQL) were applied at baseline and after 8 weeks of training. RESULTS: All assessment results significantly improved in both groups at the end of the program compared to baseline values (p < 0,05). There were significant differences between groups regarding improvements in CTRS-R/L and BRIEF-Teacher form in favor of the TT + WBVT group. CONCLUSIONS: The findings suggest that exercise training including TT and WBVT might be used in the treatment of ADHD but further research is required to provide evidence of the effectiveness of the whole body vibration training in the management of ADHD.

Researchers at the National Institute for Occupational Safety and Health (NIOSH) performed a pilot study focusing on the measurement accuracy of a mobile iOS application (app) to assess whole-body vibration (WBV) and seat performance on mobile mining equipment. The major objectives of this study were to assess the accuracy of an iPod app and determine if a pair of iPods running the iPod app were suitable to measure SEAT (Seat Effective Amplitude Transmissibility) value. The goal is to recommend a simple method to determine when a vehicle seat may need to be repaired, replaced, or adjusted. The study showed that the iPod app has the potential to serve as a low-cost tool to estimate WBV exposures to operators of mobile mining equipment. The study results were similar to those obtained by Burgess-Limerick et al. for operator WBV exposures on mining equipment. In contrast, an effort to examine seat performance using the mobile app showed greater variation between the app and the precision Siemens/LMS system selected as the “gold standard.” When comparing the Siemens/LMS and iPod pair systems, SEAT values calculated using weighted-root-mean-square acceleration (aw) resulted in a mean percent difference of 8.5±7.9%, whereas those calculated using vibration dose value (VDV) resulted in a mean percent difference of 5.5±4.4%. Additional data collection is necessary to determine what factors may be associated with this variance.
