Which tissues are most affected by microtherapy?

• A. Superficial fatty tissues
• B. Deep muscles
• C. Bone
• D. Tendons

Answer: (A)

Microtherapy delivers energy in a way that is strongest at the surface and diminishes with depth. The electrical or mechanical field is concentrated near the skin where the electrodes are placed, and it attenuates as it travels through tissue. Because of this, the superficial layers—especially the subcutaneous fatty tissue just beneath the skin—receive the most stimulation. This is why microtherapy tends to produce the most noticeable effects in superficial tissues, such as those in the fatty layer, while deeper structures like deep muscles, bone, or tendons receive much less energy and are less affected.
