Brief Summary:
This is a single blind randomised controlled trial involving healthy volunteers to determine feasibility and blinding property of two types of sham press needles.

Condition or disease Intervention/treatment Phase
Healthy Device: Ring Sham (RS) Device: Real Needle (RN) Device: Kim Sham (KS) Not Applicable

Detailed Description:
A total of 84 healthy volunteers will be recruited and randomly allocated to receive real needles (RN), previously validated Kim Sham needles (KS), or newly developed Ring Sham needles (RS) at a 1:1:1 ratio. Acupuncture sensation, blinding, and feasibility in a future clinical trial will be measured along with other physiological measurements including tactile sensitivity, interoceptive sensitivity, and electrodermal activity.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 84 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Device Feasibility
Official Title: Validation of a Newly Developed Sham Press Needle
Actual Study Start Date : April 4, 2016
Actual Primary Completion Date : June 2, 2016
Actual Study Completion Date : June 2, 2016

Arm Intervention/treatment
Experimental: Sham Press Needle - Ring Sham (RS)
A sterilised stainless steel press needle that only has the ring-shaped head of needle without needle body has three layers of adhesive tape. Between the first and second layer is the head of needle to support needle body while maintaining identical appearance and the third layer is attached to skin. RS will be placed on 1 cm medial to acupoint LI11 and ear wrist, a non-specific control auricular acupoint used in the previous literature of the non-dominant side. An acupoint detector (personal TENS electronic acupuncture, Hammtek Korea, Seoul, Korea) will be used to locate points with lower skin impedance than those nearby.
Device: Ring Sham (RS)
Active Comparator: Real Needle (RN)
A sterilised stainless steel press needle (diameter 0.18 mm X length 1.5 mm, Dongbang Acupuncture Inc., Boryeong, Chungcheongnam-do, Korea) has three layers of adhesive tape. Between the first and second layer is the head of needle to support needle body and the third layer is attached to skin. RN will be placed on acupoint LI11 and ear shenmen of the non-dominant side. An acupoint detector (personal TENS electronic acupuncture, Hammtek Korea, Seoul, Korea) will be used to locate points with lower skin impedance than those nearby.
Device: Real Needle (RN)
Sham Comparator: Kim Sham (KS)
A sterilised stainless steel press needle (diameter 0.18 mm X length 1.5 mm, Dongbang Acupuncture Inc., Boryeong, Chungcheongnam-do, Korea) with a blunted tip has three layers of adhesive tape. Between the first and second layer is the head of needle to support needle body while maintaining identical appearance and the third layer is attached to skin. KS will be placed on 1 cm medial to acupoint LI11 and ear wrist, a non-specific control auricular acupoint used in the previous literature of the non-dominant side. An acupoint detector (personal TENS electronic acupuncture, Hammtek Korea, Seoul, Korea) will be used to locate points with lower skin impedance than those nearby.
Device: Kim Sham (KS)



Primary Outcome Measures :
  1. Blinding property [ Time Frame: After needling on the 1st day visit ]
    Blinding property will be evaluated: the participants will be asked 'which type of acupuncture do you think you have received?' and choose 1 answer out of real, sham, or don't know.


Secondary Outcome Measures :
  1. Adhesive power [ Time Frame: On the next day visit (1 day after needling) ]
    It will be assessed whether sham press needle remains in place for at least 2 days (yes/no).

  2. Acupuncture sensation measured by De-qi questionnaire [ Time Frame: After needling on the 1st day visit ]
    De-qi questionnaire (Kim et al.) will be used to evaluate acupuncture sensation.

  3. Acupuncture sensation measured by De-qi questionnaire [ Time Frame: After needle removal on the next day visit (1 day after needling) ]
    De-qi questionnaire (Kim et al.) will be used to evaluate acupuncture sensation.

  4. Blinding property [ Time Frame: After needle removal on the next day visit (1 day after needling) ]
    Blinding property will be evaluated: the participants will be asked 'which type of acupuncture do you think you have received?' and choose 1 answer out of real, sham, or don't know.


Other Outcome Measures:
  1. Acupuncture Belief Scale (ABS) [ Time Frame: After needling on the 1st day visit ]
    A Korean version of Acupuncture Belief Scale (ABS), a 36-item self-report on a 5-point Likert scale will be used to evaluate acupuncture experiences and beliefs.

  2. Tactile sensitivity [ Time Frame: On the 1st day visit ]
    Tactile sensitivity will be measured using von Frey filament.

  3. Interoceptive sensitivity [ Time Frame: On the 1st day visit ]
    Using a modified method by Schandry, the participants will be asked to count their own heartbeats with eyes closed during the three counting phases that vary in length randomly, i.e. 25, 35, and 45 seconds. Beginning and end of a phase will be given verbally by the experimenter. Information on the length of the three counting phases will not be open to participants. Heart rate will also be recorded and analysed by a computer-based data acquisition system (MP150 data acquisition system, version 4.3.0, Biopac® Systems, Inc., Goleta, CA, USA).

  4. Electrodermal activity (EDA) [ Time Frame: On the 1st day visit ]
    EDA data will be obtained to evaluate autonomic response following acupuncture needling (MP150 data acquisition system, version 4.3.0, Biopac® Systems, Inc., Goleta, CA, USA).

  5. Acupuncture credibility [ Time Frame: After needle removal on the next day visit (1 day after needling) ]
    Credibility of the acupuncture treatment will be evaluated using a credibility test by Vincent et al.
