Hock Soreness in Horses: Why PEMF Beats Just Rest

Hock pain is one of the most common performance-limiting issues in horses. Rest alone doesn't always fix it. Here's what can.

"Just give him some time off." If you've had a horse with hock issues, you've probably heard this advice. And sometimes time off helps, for about a week after they come back to work. Then the soreness returns. That's because rest addresses the symptoms, but it doesn't address the underlying inflammation cycle that's driving the problem.

Why Hocks Are Such a Problem Area

The hock is one of the hardest-working joints in a horse's body. Every time your horse pushes off from behind, which is basically every stride, the hock absorbs and generates enormous force. It's a complex joint with multiple small bones, and over time, the cartilage between those bones wears down. Add in the demands of collection, jumping, or lateral work, and you've got a joint that's under constant stress.

Hock injections are the standard approach, and they work. But they're expensive, they require vet visits, and they wear off. Many horse owners are looking for ways to extend the time between injections or, in mild cases, avoid them altogether.

How PEMF Addresses Hock Pain

PEMF therapy targets the inflammation inside the joint. The electromagnetic pulses penetrate the tissue and work at the cellular level to reduce swelling, increase blood flow, and stimulate the body's repair mechanisms. For hock issues specifically, we see improvements in flexibility and willingness to engage from behind, both clear signs that the horse is more comfortable.

• Reduces inflammation within the hock joint
• Improves synovial fluid circulation
• Can extend the interval between joint injections
• Helps maintain muscle development in the hindquarters
• Non-invasive with no withdrawal period for competition

What We Recommend

For horses with known hock issues, Michelle usually recommends starting with weekly sessions for three to four weeks, then reassessing. Many horses do well on a biweekly maintenance schedule after that. She'll also look at the rest of the hind end (hamstrings, stifle, SI joint) because hock pain rarely exists in isolation. The horse compensates, and those compensations create their own problems.
