研究概览
简要总结
The goal of this clinical trial is to determine whether acupuncture can improve neck pain and shoulder movement in people with chronic neck pain. Researchers will compare acupuncture with sham acupuncture (a procedure designed to resemble acupuncture without therapeutic effects) to determine whether acupuncture provides specific benefits.
Participants will be randomly assigned to receive either acupuncture or sham acupuncture. They will attend 1 treatment session and undergo assessments of neck and shoulder movement, muscle activity, pain intensity, and neck-related disability before and after treatment. Researchers will also monitor any adverse events associated with treatment.
详细描述
The goal of this clinical trial is to learn whether acupuncture can improve neck and shoulder function in patients with chronic neck pain. It will also evaluate the effects of acupuncture on scapular movement, muscle activity, pain intensity, and neck-related disability.
The main questions it aims to answer are:
Does acupuncture improve muscle activation onset time in patients with chronic neck pain? Does acupuncture change electromyographic activity of the neck and shoulder muscles? Does acupuncture reduce pain intensity and neck-related disability?
Researchers will compare real acupuncture with sham acupuncture to determine whether the observed effects are specifically related to acupuncture treatment.
Participants will:

盲法说明
Participants were blinded to treatment allocation and informed that they would receive one of two forms of acupuncture intervention. Outcome assessors responsible for collecting clinical, kinematic, and electromyographic data were blinded to group assignment. Data analysis was performed using coded group labels to maintain blinding until completion of the primary analyses. Acupuncturists delivering the interventions were not blinded because of the nature of the treatment procedures.

结局指标
主要结局
Objective outcome (Range of Motion of the Cervical and Shoulder Joints)
时间窗: Baseline and immediately after completion of the intervention period.
The primary outcome variables were the ROM of the cervical and shoulder joints, muscle tension, and muscle activation onset time measured using surface electromyography (sEMG). 1\. Range of Motion (ROM) of the Cervical and Shoulder Joints Cervical ROM (flexion, extension, and bilateral side-bending) and shoulder ROM (flexion, external rotation and internal rotation on the affected side) were measured using a standard universal goniometer.
Objective outcome (Muscle Tension Measurement)
时间窗: Baseline and immediately after completion of the intervention period.
2\. Muscle Tension Measurement Passive mechanical properties of the muscles (upper trapezius \[UT\], lower trapezius \[LT\], and middle deltoid \[MiD\]) were evaluated using a handheld digital myotonometer (MyotonPRO, Myoton AS, Tallinn, Estonia).
Objective outcome (Muscle Activation Onset Time)
时间窗: Baseline and immediately after completion of the intervention period
Muscle activation onset time of the upper trapezius \[UT\], lower trapezius \[LT\], and middle deltoid \[MiD\], and serratus anterior (SA) during shoulder scaption was evaluated via Surface Electromyography (sEMG) (Noraxon USA Inc, Scottsdale, AZ). All procedures followed the sEMG for the Non-Invasive Assessment of Muscles recommendations.
次要结局
- Subjective Outcomes (Numerical Rating Scale)(The participants completed the Numerical Rating Scale at baseline and on days 7 and 14 post-intervention.)
- Subjective Outcomes (Neck Disability Index)(The participants completed the Neck Disability Index questionnaire at baseline and on days 7 and 14 post-intervention.)
