Özet

Background:

Mental fatigue characterized by a feeling of physical fatigue and lack of energy, resulting in the inability to maintain the attention necessary for optimal performance. This situation brings about a decrease in productivity and accidents (home, work, traffic, etc.) (Stephanie Grobe, 2017). When challenging cognitive tasks are involved, balance is compromised, and the risk of falling increases. (Kimberly A. Faulkner PhD, 2007). It is unknown whether mental fatigue caused by long-duration cognitive tasks affects postural balance control (Amanda J.Morris, 2020).

Objective:

we aimed to investigate the static balance after mental fatigue in young individuals and to investigate the effect of challenging cognitive activity after mental fatigue on static balance.

Material and Method:

Six individuals participated in our preliminary study. The static balance assessment, Ecological Momentary Assessment (EMA), Mini-Mental State Examination (MMSE), Multidimensional Fatigue Inventory (MFI), Fatigue Severity Scale (FSS), and Visual Analogue Scale (VAS) were administered to each participant before applying mental fatique, after applying mental fatique and after mental fatique plus dual task period. The mental fatique was assessed by stroop test. The static balance was assessed by posturograpy with eyes open (EO), eyes closed (EC), soft ground (SG), firm ground (FG). The dual task was assessed counting backwards during balance assessment.

Results

The difference between the ranking scores of the VAS, MFI, FSS and static balance scores applied in three different periods were tested with the Friedman Test. No difference was found in the MFI and FSS ranking scores (Asimp. P> 0.05). The VAS differences was statistically significant between before mental fatique and after mental fatique plus dual task period (Asimp p; 0.02). Whether there is a difference between the equilibrium variables in terms of positions (EO, EC, SG, FG) was also analyzed in three different periods. However, It was determined that there was no statistical difference between mental fatique periods.

Cons

When cognitive task was added to mental fatigue, a statistical difference was found in subjective rating, but this result was not reflected in static balance. Further studies should carry out with larger data samples. Altough stroop test is known to result in mental fatique in other study (Weerakkody, 2021). We didnt find statistical differences in turns of MFI and FSS. This could be because the stroop test for mental fatigue is not strong enough or because we have small data samples.
