Even after injury healing, athletes may experience persistent pain and be forced to withdraw from training for extended periods. We hypothesize that one of the causes of this is an overactive attentional function resulting from injury.
It has been reported that paying attention to noxious stimuli increases subjective pain and neural activity. However, there is evidence that attention to weak stimuli does not increase neural activity in the somatosensory cortex. This is thought to be because attention in the somatosensory cortex suppresses safe information and enhances only dangerous information. Therefore, we hypothesize that chronic pain in athletes that persists after injury healing may be caused by a breakdown in attentional function, resulting in excessive attention to mild stimuli that would not normally be perceived as painful. Therefore, this study aimed to examine the relationship between normal attentional function and neural activity in healthy individuals, providing baseline data for future research into athletes with chronic pain.
Safety,Efficacy
In this study, healthy athletes were presented with noxious thermal stimuli and non-noxious electrical stimuli, and neural activity was measured using electroencephalography (EEG).
In addition, the relationship to subjective pain was assessed using a visual analog scale (VAS).
This will provide baseline data on the relationship between normal attentional function and neural activity in healthy individuals. The findings are expected to provide a foundation for future interpretation of the relationship between attentional function and neural activity in athletes with chronic pain.
