Myofascial trigger points — muscle knots — are a ubiquitous muscular dysfunction, causing most of the aches, pains and stiffness in the world, and complicating virtually every other injury and disease process. A lot of massage is focused on them, directly or indirectly. Massage may be helpful because it relieves the symptoms of muscle knots, or even unties them. (No, not literally.)
Massage has been shown to reduce neuromuscular excitability by measuring changes in the Hoffman's reflex (H-reflex) amplitude. A decrease in peak-to-peak H-reflex amplitude suggests a decrease in motoneuron excitability. Others explain, "H-reflex is considered to be the electrical analogue of the stretch reflex...and the reduction" is due to a decrease in spinal reflex excitability. Field (2007) confirms that the inhibitory effects are due to deep tissue receptors and not superficial cutaneous receptors, as there was no decrease in H-reflex when looking at light fingertip pressure massage. It has been noted that "the receptors activated during massage are specific to the muscle being massaged", as other muscles did not produce a decrease in H-reflex amplitude.
