YOUR PATH TO RECOVERY
WHAT TO EXPECT
DURING MAT® THERAPY
MAT® is a hands-on neuromuscular therapy focused on identifying and correcting muscle inhibition – the root cause of tightness, pain, and limited mobility.
IDENTIFY
Find the Weakness
Targeted muscle testing pinpoints the specific inhibited muscles that are causing your body to compensate, leading to tightness and pain.
ACTIVATE
Restore Function
Through precise hands-on techniques – targeted pressure or isometric force – your practitioner restores proper neuromuscular signaling and function.
Sessions run 50-55 minutes. Many clients notice improvements after the very first session – reduced pain, increased range of motion, and better overall muscle function.
