Effects of athletic conditioning on horses with degenerative suspensory ligament desmitis: a preliminary report.

The research investigated the effects of regular exercise on horses with a type of ligament degeneration known as DSLD. They found that exercise did not worsen the condition and might even have led to improvements.

Objective of the Study

• The focus of this research was equine degenerative suspensory ligament desmitis (DSLD), a condition causing ligament degeneration in horses that traditionally has shown little response to treatments like rest or confinement to a stall.
• Despite the usual treatment methods, the researchers set out to test whether exercise could potentially benefit horses suffering from mild to moderate DSLD. Their hypothesis was that consistent physical activity wouldn’t worsen the condition and might contribute to improvements.

Study Methodology

• The animal subjects were Paso Fino and Peruvian Paso horses. These included two normal, or control, horses, and four horses diagnosed with DSLD.
• Over eight weeks, all horses were subjected to a routine of consistent exercise – 30 minutes every other day. After this exercise trial, they were rested in a pasture for four months.
• The team conducted gait analysis, took radiographs and ultrasounds, and monitored serum insulin and glucose levels. These were performed before starting the exercise trial and at each following time point.

Key Findings

• After eight weeks of continual exercise (followed by four months of rest), horses with the DSLD condition displayed an increased vertical impulse. This suggests that their ability to convert muscular movement energy into motion had improved.
• Further, an improvement was noticed in the subjective ligament fiber pattern of the horses with DSLD. This could indicate a potential positive effect of exercise on the condition.
• In all the horses, a significant decrease in insulin levels was observed after four and eight weeks of regular exercise.
• The results suggest that in cases of mild to moderate DSLD, regular exercise may not exacerbate the health issue. There’s even a possibility that it might help alleviate the condition’s effects.
