| Outline of Final Research Achievements |
The purpose of this study was to examine the effect of progressive muscle relaxation (PMR), a mental training technique, on spinal motoneuron pool excitability during movement immediately after performing PMR. As a first experiment, before and after engaging in PMR in the right-foot phase, voluntary ankle dorsiflexion (motor task) of the right foot was performed, and spinal motoneuron pool excitability was assessed by measuring the H-reflex of the soleus during the dorsiflexion part of the motor task. Furthermore, as a second experiment, PMR was performed in the left-foot phase and its effect on the H-reflex of the soleus during the motor task in the right foot was examined as in the first experiment.Both the first and second experiments revealed no changes in the H-reflex amplitude value during the motor tasks before and after performing PMR. No facilitatory effect on the excitability of the spinal motoneuron pool excitability was observed in movement immediately after performing PMR.
