Brief Summary:

The purpose of this study is to develop and test a sensor system capable of measuring acupuncture needle manipulation and torque in a clinical setting.

Study hypothesis: Torque will be greater on the side of the back with musculoskeletal pain compared with the side without pain.

Condition or disease Intervention/treatment Phase
Back Pain Procedure: Acupuncture Phase 1

Detailed Description:

Acupuncture is an ancient Chinese practice that involves the use of specialized needles to stimulate parts of the body. The number of Americans who use acupuncture services continues to grow each year. Two elements required to deliver high-quality acupuncture treatment are identification of the appropriate acupuncture points and proper manipulation of the acupuncture needle. Despite a growing awareness of the importance of proper needle techniques, no tool capable of objectively measuring needle manipulation in a clinical setting has ever been developed. Such a tool would have applications in acupuncture research, teaching, and clinical practice.

This study will develop and test a simple hand-held sensor capable of making such objective needle torque measurements.

There are two parts to this study. In Part 1, researchers will develop the hand-held sensor (called the AcuSensor) that will be mounted to the handle of an acupuncture needle and will measure torque during manual needle manipulation.

In Part 2, the sensor will be tested for accuracy and reliability in three different groups. Group 1 will consist of patients with unilateral musculoskeletal back pain. Group 1 participants will undergo one session of acupuncture treatment while torque measurement and needle manipulation techniques are examined. In Group 2, practitioners and students at two leading acupuncture schools will use the AcuSensor during their teaching clinics. Teachers and students will complete a questionnaire to evaluate the sensor's usefulness. Experienced acupuncturists comprise Group 3; they will receive AcuSensor training and evaluate the performance of the AcuSensor in clinical practice. Information about the range and variability of torque measurements produced by different practitioners and techniques will be obtained from use of the sensor. Group 3 acupuncturists will also guess needle torque before and after training with the sensor turned off in order to determine the way AcuSensor training affects acupuncturists' sensory perception of needle grasp.
