Q

What are the differences between NMES and TENS

A

NMES is for Muscle Weakness targeting MOSTLY Type I (slow twitch cardio) muscles fibers after initial Type II (fast twitch strength) fibers to create tetanic contractions of selected muscle groups WITHOUT PAIN

TENS is for Pain relief and uses hyper stimulation of nociception (pain gate theory) to release enkephalins (sensory level) and/or endorphins (motor level)

Cells in blood and lymph will migrate to the Tx area to induce autocrine, paracrine and endocrine (bystanders) effects

70
Q

How does LLLT produce analgesia?

A

Laser (>300 me/cm^2) absorbed by nociceptors which inhibit specific pain fibers, slow conduction velocity, reduce AP amplitude and suppress neurogenic inflammation

71
Q

Why does PBM work on MTPs?

A

There is high electrical activity at these locations, LLLT reduces the amplitude of the APs to reduce pain

72

A

1-5 J/cm^2 which can increase collagen production, greater than 5 will inhibit and delay healing

75
Q
