| Abstract |
Objective
To evaluate the effect of hyperbaric air therapy (HAT) on activity of cerebral motor cortex
Method
Eighteen right-handed subjects were recruited, who had no brain lesion and did not take any medication that can affect brain function. Experimental group (n=9) underwent motor evoked potential (MEP) study by transcranial magnetic stimulation before and after 1-hour HAT. Control group (n=9) also received motor evoked potential study twice with 1 hour interval. The cortical activity was evaluated with parameters such as resting motor threshold (rMT), amplitude of MEP, intracortical inhibition (ICI) and intracortical facilitation (ICF) and recruitment curve (RC).
Results
There was no significant difference of rMT, MEP, ICI, ICF and RC between experimental group and control group.
Conclusion
One -hour hyperbaric air therapy could not modulate any cortical motor activity in health human brain. (J Korean Acad Rehab Med 2005; 29: 38-42) |
