- Mechanical
- Reflexive
- Physiologic
- Psychological
Mechanical
How does soft tissue massage (STM) affect our nervous system?

To identify areas of restriction
T or F? Effleurage is used before petrissage
True
What is effleurage?
STM technique that consists of short or long strokes going in the direction of the heart to stimulate blood flow
What is petrissage?
STM technique consists of kneading motions to target deeper layers of tissue

What is HLLT?
High Level Laser Therapy
- Max power output is greater than 500 MW
- Can produce perceptible heating of tissues
What is LLLT?
