Clinical Effectiveness of Dry Needling on Myofascial Trigger Points in Horses: A Prospective Algometric Controlled Study.
Abstract: Myofascial pain syndrome (MPS) is caused by trigger points (TrPs): hypersensitive spots in taut muscle bands that impair function and cause pain. Dry needling (DN) is a common treatment in humans, but evidence in horses is limited. This prospective, controlled study evaluated the effectiveness of DN in reducing TrP-related pain in the brachiocephalic muscle of horses. Of the 98 horses enrolled, 66 were allocated to a treatment group receiving weekly DN sessions for three weeks, while 32 were assigned to a control group with no intervention. Pain and function were assessed using pressure algometry, a numerical rating scale (NRS), a functional total test score (FTTS), and behavioral indicators including jump sign (JS), equine pain face (EPF), and local twitch responses (LTRs). Assessments were performed at baseline and at 0, 4, 24, and 72 h post-intervention. Results indicate a significant increase in pressure pain thresholds ( < 0.001), especially after the second and third sessions. Both NRS and FTTS improved significantly over time ( < 0.001), and LTRs progressively decreased. EPF and JS showed minimal variation. These results support the use of DN to reduce local muscle pain and improve function in horses with TrPs. Further robust studies are warranted to refine protocols and investigate long-term effects.

This study explores the effectiveness of dry needling in alleviating pain from trigger points in horses. It demonstrated successful results in increasing pain thresholds and improving overall function over time.
Defining the Problem
- Myofascial pain syndrome (MPS) is a condition characterized by pain and decreased function caused by trigger points (TrPs), which are hypersensitive spots found within rigid bands of muscles.
- Treatment for MPS in horses is not fully researched; the intervention of dry needling (DN), widely used in humans, has limited evidence of its efficacy for horses.
Study Design and Procedures
- The authors conducted a controlled, prospective study to assess the impact of DN on alleviating pain from TrPs in the brachiocephalic muscle of horses.
- A total of 98 horses participated in the study. Sixty-six horses were assigned to the treatment group that received weekly DN treatment for three weeks, while 32 got no intervention.
- Pain and function were evaluated through various tools: pressure algometry, a numerical rating scale (NRS), a functional total test score (FTTS), and behavioral indicators such as jump sign (JS), equine pain face (EPF), and local twitch responses (LTRs).
- These assessments were carried out at baseline and at 0, 4, 24, and 72 hours after treatment.
Key Findings of the Study
- Results showed significant improvement in pressure pain thresholds, particularly after the second and third DN sessions.
- Numerical rating scale (NRS) and functional total test score (FTTS) reported noticeable improvements over time.
- The horses’ local twitch responses (LTRs) decreased progressively with each treatment session.
- However, the jump sign (JS) and equine pain face (EPF) showed little changes.
Implications of the Research
- The findings suggest that dry needling is an effective intervention to reduce muscular pain and improve function in horses suffering from trigger points.
- This study advises a need for further robust research to optimize treatment protocols and explore long-term effects of dry needling in horses.
