Summary
Brief summary
We recently published a new analgesic method, acute pressure on sciatic nerve for short-term pain relief.
We propose that the method can be improve to be self-practiced.
The purpose of this study is to avaluate a self-practice method for the application of acute pressure on scaitic nerve for pain relief.
