Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1.Functional MRI (fMRI) of Needle acupuncture at LR8 at medial knee (located between the tendons of semitendinosis and semimembranosis muscles) followed by, in same session
2.Functional magentic resonance imaging (fMRI) continues while Laser acupuncture (low level -804nm, Energy delivered Total 2.56J) at the opposite side LR8 acupoint is delivered.
3.N=16, eight healthy subjects per arm, order of Note:Laser or Needle first is randomised. 4.Single session. Duration approximately 20minutes in the scanner.
5.Block design. 16 second blocks with rest and active intervention ( needle or laser) alternating blocks. Total 9 Rests and 8 actives.
6. Active laser being 20mW low level laser activation in the 16 second blocks.
7. Needle being 0.22 x 25mm silver disposable Helio acupuncture needles stimulated at 1Hz cycles to achieve the sensation of "de qi" like a dull ache.
Intervention code [1] 256363 0
Treatment: Other
Comparator / control treatment
Not applicable. This is a basic science experiment to test what needle acupuncture does compared to laser acupuncture on LR8 acupoint in brain activation patterns, when both interventions are performed on the same subject in the same session.
Control group
Uncontrolled

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)
1. recruitment was by group internal email at the University, Black Dog Institute and Prince of Wales Hospital as well as by advertisement flyers at the participating medical acupuncturist's clinical rooms.
2. treatment allocation was by the medical acupuncturist, allocation to which intervention ( laser or needle) on which side ( left or right) by paper lots so that in the end, half ( n=8) were needle acupuncture first and half were laser acupuncture first ( n=8) in the block design .
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
1. Sidedness ( left or right)
2. Intervention ( needle or laser)
were decided on the day for each subject by toss of a coin.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Single group
Other design features
1.Block design with rest -active -rest -active blocks, in total 9 Rests and 8 Active

2.Intervention ( Needle or laser):

The silver 0.22 gauge x 25 mm silver needles were manually stimulated for de qi sensation at 1 HZ cycles for 16 seconds per block

Low level laser was with 804nm infra red laser 20mW for 16 second per block.
