Thuasne BOA SI Belt Back Brace

Low back pain is one of the most common conditions for sportspeople and can affect athletes in most sports. If you suffer from discomfort in this region, it could be an unforgiving symptom of other issues, such as dysfunction of the sacroiliac (SI) joint. The Thuasne BOA SI Belt Back Brace helps stabilise the area to relieve pain and inflammation so you can get back to your normal training routine again.

Who Can Make Gains with the BOA Belt Back Brace?

Although the SI joint doesn't often get damaged, falling down hard can cause pain and dysfunction in the area. The BOA SI Brace compresses the hips and SI joint to relieve discomfort and protect it from further injury. While you should rest when you're suffering from this injury, the support can help you heal quickly so you don't miss too many sessions.
