Electrohydraulic Shockwave for Treatment of Forelimb Superficial Digital Flexor Tendinitis and Proximal Suspensory Desmitis in Horses.

This article studies how efficient electrohydraulic shock wave therapy (ESWT) is in managing superficial digital flexor tendinitis and proximal suspensory desmitis in horses. It compares the impacts of three or more versus fewer than three ESWT treatments. The study concludes by pointing out that ESWT reduces lameness significantly but doesn’t considerably alter ultrasound findings. Time is a significant factor in achieving good results, independent of the number of treatments.

Research Context

• Superficial digital flexor tendinitis (SDFT) and proximal suspensory desmitis (PSD) are common conditions that result in lameness in horses. Traditional treatments include rest, exercise control, anti-inflammatories, intralesional injections, and surgery.
• The study focuses on the use of electrohydraulic shock wave therapy (ESWT) as a treatment alternative because it is noninvasive and safe. They are also used in treatment of different musculoskeletal conditions.
• Medical records between 2010 and 2021 were used for the study in which the subjects of the investigations were grouped into two; those who received three or more ESWT treatments (group 1), and those who received less than three treatments (group 2).

Findings

• According to the study, lameness scores improved significantly between the first and third ESWT sessions in horses suffering from both SDFT and PSD. More specifically, group 1, which received three or more treatments, exhibited this change significantly.
• Despite the improvement in lameness scores, ultrasound findings of the PSD or SDFT were not considerably different after the third treatment.
• Notably, horses suffering from PSD showed significantly improved lameness in forelimbs when compared to hindlimbs. This was observed between the first and third ESWT treatments.

Interpretation

• From a multivariable ordered logistic regression model, consistent follow-up time is significantly associated with a positive outcome. This implies that the duration of follow-up is a crucial factor in achieving good results from these treatments.
• The study indicates no difference in short-term and long-term outcomes between the two groups, regardless of the number of ESWT treatments received.
• Furthermore, the study found out that the extent of the injury (chronicity) was negatively associated with improvement of lameness. This means that horses with more severe or long term injuries showed less improvement.
