This experiment has certain limitations,one of which is the lack of supervision of the patient’s self-stretching. To cover the ethical and feasibility considerations, this study compared two treatment groups, but no placebo group was used in this experiment. Because current studies have shown no correlation between pain and osteoarthritis classification, this experiment did not analyze and statistics according to the classification of osteoarthritis. Most of our follow-ups were conducted by telephone because the patient was too old and has limited physical mobility. Therefore, no ROM was measured. However, the patient may not have completed the recommended exercise. Finally, previous studies primarily focused on active trigger points, that is, inactivate active trigger points to latent trigger points. However, how to evaluate the effect of dry needling on latent trigger points requires further research to investigate this important issue. The pressure pain threshold (PPT) may have important value for the evaluation of latent trigger points; however, there was no record due to a lack of appropriate instruments.
