Brief Summary

The aim of the present study was to evaluate whether hyperbaric oxygen (HBO) environment, with increased oxygen supply to the brain, will enable better performance of complex and/or multiple activities.

Conditions

Cognitive Change

Keywords

Hyperbaric oxygen; multitasking performance; cognitive funcitons

Outcome Measures

Primary Outcomes (2)

• Cognitive/Attention Symbol-Digit Modality Test (SDMT)

  Three different forms of the SDMT were used in each evaluation session. The first was a try-out for the test, ensuring understanding of the task. The second tests the ability to per-form an individual task. The third form was used together with the motor test for examin-ing dual task performance. Standard administration procedures were followed as indicat-ed in the test manual. The score of the test is the number of correct substitutions during 90-second interval.

  45 minutes

• Motor task: transferring of beans

  Motor performance was evaluated by the Motor Assessment Scale test (MAS) - transfer-ring units of beans one by one between two tea cups an arm length away.
