Objectives

This study aimed to investigate the efficacy of ultrasound-guided precision acupuncture and knife therapy for cervical myofascial pain syndrome.

Methods

One hundred patients were randomly divided into an intervention group and a control group from December 2023 to December 2025, with 50 patients in each group. The intervention group received ultrasound-guided precision acupuncture and knife therapy, while the control group received conventional small acupuncture and knife therapy, once a week for 4 consecutive weeks. The visual analog scale (VAS) score for pain, pain pressure threshold (PPT), neck disability index (NDI), cervical spine mobility, and quality of life scores were compared between the two groups before and after treatment.

Results

The total effective rate in the intervention group was 92.00%, significantly higher than the 72.00% in the control group ( P  < 0.05). After treatment, the VAS and NDI scores in the intervention group were significantly lower, while the PPT value and cervical spine mobility in all directions were higher than those in the control group ( P  < 0.05), and there was no significant difference in the incidence of adverse reactions ( P  > 0.05).

Conclusions

Ultrasound-guided precision needle knife therapy can effectively relieve pain, increase the cervical tenderness threshold, improve cervical dysfunction, and enhance patients’ quality of life. It has good safety and clinical application value.
