Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Three-minutes pressure with the dorsal proximal phalangeal surface of the fists was applied simmultaneously to the sciatic nerves on the center of back legs. The pressure is 15-20 kg per hand.
Patients were randomized to receive placebo or treatment intervention group. Each patient is allowed to join once the study, and receive once the 3-minutes' pressure.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients have never been exposure to this analgesic method before, then are unware of the difference between placebo and treatment.
All the introduction and procedures are same to the patients from both treatment and placebo group, except the different level pressure, which blind to patients, but not to physicians.
Each patient draws from an envelop a number which shows the allocation group the subject would be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
We recently published a few studies of a new analgesic method, acute pressure on sciatic nerve for short-term pain relief (ACTR 12606000439549).
The purpose of this study is to examine one of my hypothesis regarding the method that acute pressure on the sciatic nerve relieves the sciatic pain caused by chronic pressure on the sciatic nerve.
