Muscle Activation and Inhibition: GTOs, spindles and reciprocal inhibition

Methods of activation and inhibition of muscles using the GTOs and spindle receptors. Also, therapeutic use of reciprocal inhibition is presented to improve stretch therapies

Thank you! I've seen this material presented a few times, but the way you presented it really gets through to me.

[@samirbitar806]

thank you! you're a very good teacher. i've read and reread NASM's written description scores of times. its authors never come close to your clarity. thank you!!

Amazing video finally I found someone who I could understand this thank u for sharing

[@NeuroDocUniverse]

You're welcome!

thanks for sharing this !!!
I'm searching for the information & theory of AMIT (advacne muscle integration technique) for this couple few days,
and it really gives me some clues. :)
it's really helpful for me as a physical therapy ! thanks again!

spindle cell in the brain allow higher functions ie love;
Spindle neurons are relatively large cells that may allow rapid communication across the relatively large brains of great apes, elephants, and cetaceans. Although rare in comparison to other neurons, spindle neurons are abundant, and large, in humans

[@MauiXoXo]

Thank you for this presentation.

[@alsa3644]

Thank you for sharing this. So to clarify, if you want to activate week rhomboid. Do you move your thumb from musculotendenous junction toward middle and in pec minor, from middle toward origin and insertion ?

[@darrenkelly6782]

Enjoyed this presentation. Could I ask you a quick question. I have a problem on my left side where the gluteus medius feels to be doing all the work on that side and is tight and the gluteus maximus appears totally inhibited but should be the primary mover..how do I awaken this and that the effort off the gluteus medius?

[@NeuroDocUniverse]

Hi Darren, So sorry you're having this trouble. There is no way that I can recommend treatment without a thorough hx and exam. A certified Applied Kinesiology practitioner would know how to check to see if recipr. inhibition problem and correct it.

[@SherringenergyTeez]

Isnt the pec minor more of a shoulder depressor and wouldn’t activating the lower traps be more opposing than the rhomboids?

[@tayloreathorne3514]

Pec minor is both a depressor and a protractor of the scapula and also a downward rotator.

[@dredredringoproject]

Facts. Thanks

It's like my 4 year old drawing a picture.

[@samuelgomez1190]

1. So if I have right rectus femoris, and weak stretched out hamstrings, would I activate GTO reflex on the quads, and activate the muscle spindles in the hamstrings?
2. Same scenario, if the hamstrings are in pain, fatigued and overstretched due to tightquads, will activating the muscle spindle in the hamstrings to contract them cause more pain?

[@samuelgomez1190]

Tight* not right

[@lisakbloomdcphd2114]

Hi Samuel - Treatment scenarios are complex. Quads could be problematic because the psoas (primary hip flexor) isn't firing properly on its own or in gait. To answer your question broadly a weak muscle (hamstrings) could be activated by addressing the spindle receptors in that muscle OR by addressing the GTOs in the muscle that does the opposite action (quads). The success of the treatment is based entirely on the accuracy of the diagnosis. I hope this helps. If not, write back!

[@giojean-louis2656]

Great video, however, I am a little confused when you said by contracting the rhomboids, that would inhibit the Muscle spindles for the Pec Minor. How is that possible? I thought when you contract one muscle (activating the GTOs which inhibits that muscle), then the opposing muscle would be activated. So my thought process from your video is telling me that when you contract the rhomboids, then the pec minor is being activated not inhibited. Hoping for a speedy response!

[@NeuroDocUniverse]

Good question! There are two systems in play. Once system is intramuscular. The spindles and GTOs can be activated or inhibited manually.
The other more global system is reciprocal inhibition where an activated muscle or group of muscles can lead to inhibition of the muscles that have the opposite action. For example, activating the quadriceps inhibits the hamstrings.
Putting the two systems together, activation of the quads inhibits the general activation of the hamstrings and also inhibits the spindle receptor sensitivity to stretch. Let me know if you need more clarification.

[@giojean-louis2656]

@@NeuroDocUniverse Okay so if I'm understanding correctly, contracting the rhomboids is activating it's GTOs thus inhibiting the GTOs for the Pec minor?

[@NeuroDocUniverse]

@@giojean-louis2656 The reciprocal inhibition mechanism is not controlled via the intramuscular system (GTOs and spindle receptors), but through inhibitory neurons in the spinal cord.

[@chelsycalhoun4422]

are you a DO sounds like FPR technique for the gto

[@NeuroDocUniverse]

Hi! The technique is part of Applied Kinesiology and is used by many manual therapists.

[@femorisable]

to strengthen “weak” muscles due to inhibition of the muscle via muscle spindle cell, Golgi tendon organ and Golgi ligament organ receptors whose job it is to “protect” the structural integrity of the muscle and its related tendons and ligaments should tension on the muscle exceed a threshold level. Our bodies come up with masterful ways to protect us - yes we need interventions and do you really think you are changing the efferent and afferent communication?
remember sensory receptors are the muscle spindles or intrafusal fibers(which there are static and dynamic ones that are sensitive to different stretch) transduce information about length and rate of change of the length of the muscles while The Golgi tendon organs signal the forces generated by the muscles. The stretch the intrafusal fibers sense are the basis of our concentric contractions while there are intrafusal fibers responding to an opposite eccentric contraction to the opposing musculature to stabilize the joint to maintain its' health as it moves through the chosen range of motion.
what you think you are doing "therapeutically" is hog wash- the alpha gamma motorneurons will out smart you every day.
