The needles will be inserted to 12.5-30 mm in acupoints through adhesive pads. Needles will be lifted, thrusted and twirled gently for 3 times to achieve deqi sensation and manipulated every ten minutes.
The needle will be inserted to 2-3mm in sham Baihui acupoint. For the remaining sham acupoints, needles will be inserted into the pad and reaching the skin. Needles will be lifted, thrusted and twirled gently for 3 times to simulate the effect of the needle tip penetrating the skin.
The change in average 24h overall neck pain intensity measured by NRS from baseline over the past week
The NRS score ranges from 0 to 10, with higher scores indicating more severe pain.
Time frame: week 5
The change from baseline in the Chinese version of the Insomnia Severity Index (ISI-C) scores.
The Chinese version of the Insomnia Severity Index (ISI-C) will be used to assess the severity of patients' self-perceived insomnia symptoms. Each item is rated on a scale from 0 to 4, with a total score ranging from 0 to 28. Based on the total score, the severity of insomnia can be categorized into four levels: a score of 0-7 indicates "no clinically significant insomnia," 8-14 indicates "subclinical insomnia," 15-21 indicates "clinical insomnia (moderate)," and 22-28 indicates "clinical insomnia (severe)."
Time frame: week 5
The change in average 24h overall neck pain intensity measured by NRS from baseline over the past week
The NRS score ranges from 0 to 10, with higher scores indicating more severe pain.
Time frame: week 9 and 16
The change from baseline in the ISI-C scores.
The ISI-C will be used to assess the severity of patients' self-perceived insomnia symptoms. Each item is rated on a scale from 0 to 4, with a total score ranging from 0 to 28. Based on the total score, the severity of insomnia can be categorized into four levels: a score of 0-7 indicates "no clinically significant insomnia," 8-14 indicates "subclinical insomnia," 15-21 indicates "clinical insomnia (moderate)," and 22-28 indicates "clinical insomnia (severe)."
Time frame: week 9 and 16
The proportion of participants with at least 30% reduction in NRS scores from baseline
The NRS score ranges from 0 to 10, with higher scores indicating more severe pain.

Time frame: week 5, 9 and 16
The proportion of participants with at least 6 points reduction in ISI-C scores from baseline
The ISI-C will be used to assess the severity of patients' self-perceived insomnia symptoms. Each item is rated on a scale from 0 to 4, with a total score ranging from 0 to 28. Based on the total score, the severity of insomnia can be categorized into four levels: a score of 0-7 indicates "no clinically significant insomnia," 8-14 indicates "subclinical insomnia," 15-21 indicates "clinical insomnia (moderate)," and 22-28 indicates "clinical insomnia (severe)."
Time frame: week 5, 9 and 16
The change from baseline in the total score of the Neck Disability Index (NDI).
Neck Disability Index (NDI) consists of 10 items, with a total score ranging from 0 to 50. A higher score indicates a greater impact of neck pain on quality of life.
Time frame: week 5, 9 and 16
The proportion of participants with at least 10 points reduction in NDI scores from baseline
NDI consists of 10 items, with a total score ranging from 0 to 50. A higher score indicates a greater impact of neck pain on quality of life.
Time frame: week 5, 9 and 16
The change from baseline in the maximum pain intensity score on the NRS during six directions of neck movement.
The NRS score ranges from 0 to 10, with higher scores indicating more severe pain.
Time frame: week 5, 9 and 16
The change from baseline in the Pittsburgh Sleep Quality Index (PSQI).
The PSQI has a total score ranging from 0 to 21. A higher score indicates poorer sleep quality. Specifically, a total score of 0-5 indicates very good sleep quality; 6-10 indicates fairly good sleep quality; 11-15 indicates average sleep quality; and 16-21 indicates poor sleep quality.
Time frame: week 5, 9 and 16
The change from baseline in the Hospital Anxiety and Depression Scale (HADS) scores.
The HADS score ranges from 0 to 42, with higher scores indicating greater anxiety and depression.
Time frame: week 5, 9 and 16
The proportion of responders per the Patient Global Impression of Change (PGI-C)
The PGI-C evaluates the overall treatment effect perceived by patients themselves. The change can be rated in 7 levels, including "very much better", "moderately better, "a little better", "no change", "a little worse", "moderately worse" or "very much worse".
Time frame: week 5 and 16
The percentage of patients who used rescue analgesics and sedative-hypnotics.
The percentage of patients who used emergency analgesics and sedative-hypnotics.
Time frame: week 5, 9 and 16
The total number of days of using rescue analgesics and sedative-hypnotics.
The total number of days of using rescue analgesics and sedative-hypnotics.
Time frame: week 5, 9 and 16
Blinding assessment
In this trial, two types of acupuncture treatments were used: traditional acupuncture, which has a stronger sensation of needle insertion, and modern acupuncture, which has a weaker sensation of needle insertion. Patients were asked which type of therapy they thought they had received.
Time frame: Within 5 minutes after the last treatment at week 4.
