Short-Term Impact of Dry Needling Treatment for Myofascial Pain on Equine Biomechanics Through Artificial Intelligence-Based Gait Analysis.

Abstract: Myofascial pain syndrome (MPS) is a common source of musculoskeletal pain, characterized by trigger points (TrPs). In horses, MPS is frequently underdiagnosed, and evidence on DN effectiveness is limited. This study investigated whether DN can improve the biomechanics in horses using an artificial intelligence (AI)-based markerless smartphone application (app). Fourteen horses participated, including nine used in assisted therapy, four leisure horses, and one with mixed use. The presence of TrPs was evaluated in six muscles through manual palpation: brachiocephalicus, trapezius, gluteus medius, biceps femoris, semitendinosus, and quadriceps femoris. The horses were divided into a treatment group (TG) (n = 7) and control group (CG) (n = 7). Biomechanical data were recorded in a straight line at a trot before the treatment (T0), immediately after the treatment (T1), and 72 h post-treatment (T72). The stride frequency (SF) was significantly lower (p < 0.05) at 72 h compared with both before and immediately after the treatment. The SF of the TG at 72 h was significantly lower than the SF of the CG at T1 (p < 0.05). Non-significant differences were observed for both the asymmetry push-off and impact phase variables, except for the forelimb head range of motion (FHROM) severity, which was significantly (p < 0.05) greater in the CG than in the TG. This study suggests that DN may enhance the gait quality in horses with MPS.

The research investigates the impact of Dry Needling (DN) on horses suffering from musculoskeletal pain, using an AI-based application to perform gait analysis and monitor changes post-treatment. The study finds that there are potential benefits of DN on horses’ gait quality and biomechanics.

Introduction

The research focuses on horses suffering from Myofascial pain syndrome (MPS), a common musculoskeletal disorder characterized by trigger points (TrPs). The applicability of Dry Needling (DN), a common physiotherapy technic, in horses is understudied and not fully understood. This study aims to rectify this gap and provide valuable evidence on the effectiveness of DN in improving the biomechanics of afflicted horses. In order to evaluate changes, a novel AI-based markerless smartphone application is utilized for gait analysis.

Method

  • Fourteen horses were involved in the study, nine of which were used in therapy, four kept for leisure and one multi-purpose horse.
  • Each horse was evaluated via manual palpation for the presence of TrPs in six different muscles including brachiocephalicus, trapezius, gluteus medius, biceps femoris, semitendinosus, and quadriceps femoris.
  • The horses were then segregated into two groups: a treatment group (TG) that numbered 7 horses, and a control group (CG) with an equal count.
  • Using the smartphone application, all horses were recorded trotting in a straight line. This analysis was conducted at three intervals: before treatment (T0), immediately after (T1), and 72 hours post-treatment (T72).

Results

  • The stride frequency (SF) was observed to be significantly lower 72 hours after the treatment as compared to both the before and immediately after treatment times.
  • Further, the SF of the TG was noticeably lesser than that of the CG post 72 hours, indicating a possible impact of the DN treatment.
  • No significant differences were noted in the asymmetry during the impact and push-off phases, except for the Forelimb Head Range of Motion (FHROM) severity. This was observed to be significantly higher in the CG horses.

Conclusion

The research indicates that Dry Needling may have a positive impact on gait quality in horses suffering from MPS. Visible changes in stride frequency in treated horses, as indicated by AI-based gait analysis, provide promising evidence towards the potential benefits of DN treatment in managing musculoskeletal conditions in horses. Further research with larger sample sizes and more variables will help solidify these findings.
