Background: Limited research has explored the effectiveness of meridian-based exploration of wrist
and ankle acupuncture on pain.

Objective: To investigate the impact of meridian-based exploration of wrist and ankle acupuncture
on pain and quality of life in patients suffering from pain due to lung cancer bone metastasis.

Methods: Eighty patients were selected and randomly divided into an observation group and a
control group, each comprising 40 cases. The observation group explored acupuncture points
along the 12 meridians of the human body to target the most painful areas, while the control group
received conventional wrist and ankle acupuncture targeting fixed acupuncture points. After a 2-week
intervention period, both groups were assessed for pain intensity using the numerical rating scale
Oral Presentation Abstracts
(NRS), onset and duration of analgesia, quality of life (including physical, cognitive, pain, emotional,
and overall quality of life), the occurrence of adverse reactions, and overall effectiveness.

Results: The observation group exhibited a significantly higher total effective rate (90.0%) compared
to the control group (75.0%) (P<0.05). Furthermore, the observation group showed greater reductions
in NRS scores post-intervention compared to the control group (P<0.05). Additionally, the onset of
analgesia was shorter and the duration of analgesia was longer in the observation group compared
to the control group (P<0.01). The quality of life scores in the observation group were significantly better
than those in the control group (P<0.01). Although the incidence rate of adverse reactions was slightly
lower in the observation group (5.0%) compared to the control group (7.5%), the difference was not
statistically significant (P>0.05).

Conclusion: Meridian-based exploration of wrist and ankle acupuncture, targeting the most painful
points, demonstrated superior efficacy in alleviating pain and improving the quality of life in patients
with lung cancer bone metastasis pain compared to conventional fixed-point acupuncture. This
innovative approach represents a promising advancement in acupuncture therapy and warrants
further promotion.
