For a long time the main challenge in PE for me has been heating hard, collagenous tissue to a sufficient temperature so that it’ll be more willing to extend and hopefully deform. I’ve always assumed infrared light to be the best way to go about this. But what about ultrasonic? I know it can be used to heat deep tissue more effectively and far faster than infrared light, which needs to gradually penetrate the layers of soft tissue and heat them up in turn before the underlying ones will be heated, whereas ultrasonic soundwaves, not being electromagnetic in nature, but being like normal sound waves, that is, the vibration of whatever medium the kinetic energy is moving through.

Would it be safe to use directly on the penis? Would it be a good way of heating collagenous tissues, particularly the ‘dorsal cord’ I and many others are plagued with? Does anyone know?

No direct citations, unfortuantely.

Now that I think about it, I know ultrasonic sound can (but isn’t necessarily) safely used on the penis, since there are diagnostic tools such as the ‘doppler ultrasound’ which, obviously, use ultrasonic sound waves directly on the penis to produce an image of what’s happening inside.

I’ve thought of this a few times - and have not yet had a satisfactory reply, so I will be interested to hear about this too..

Firegoat made a post in the past about this and if I remember correctly he suggested just sticking with a heatpack.

I’m interesting in using something like this in combination with with a hanging routine and/or an ADS. If the tissues are softened up (ie, the collagen especially), one could use lower hanging weights with hanging or less force on an ADS to achieve the same results, in theory. As Bib says, always better to use the lightest weight that causes fatigue.

Or would this just be a tool to help with healing?

Temperature Increases in the Human Achilles Tendon During Ultrasound Treatments With Commercial Ultrasound Gel and Full-Thickness and Half-Thickness Gel Pads - PMC

Pertinent study.

In that study they were attempting to determine the most effective thickness a gel pad should be to transmit the ultrasonic waves in the Achilles tendon. They use a 3MHz ultrasound. I am interested in whether a 1MHz, which penetrates more deeply (~4inches), or a 3MHz ultrasound (~2inches) would be more useful for our purposes. Considering the human penis is rarely more than 2 inches in any depth, and the ultrasound can obviously be pointed at the penis from any direction, the 3MHz ultrasound may be more efficacious since the amount of energy being transmitted, I think, will not be altered, merely the location of its concentration. Since the 3MHz ultrasound is likely, from any direction, to penetrate entirely through the penis, perhaps it would be a better option, though I haven’t by any means decided whether defiantly to try it, though I’m getting closer :)

This a commercial site but appears to have some useful information here too: http://www.aidyourpain.co.uk/

Didn’t get a chance to read them cause I’m on my way out in a rush but these two articles, both free, may prove extremely informative!

My thoughts haven’t changed either. IR or a microwaveable gel-pack wrapped in damp, thin towel/t-shirt material does the job best.

You want all the tissues you are stretching heated, not just localised ones. Anything you can do with ultraound you can do just as well with one of the above.

I stopped using ultrasound in my clinic a long time ago, except for very specific uses. It’s just the ‘lazy way’ - there are far more effective methods of doing anything an ultrasound machine can do, it’s just harder work.

FG I find my skin ends up getting too hot before the inner tissue is the desired temperature. I feel ultrasound could eliminate this issue.

Do you think the ultrasound at the frequencies mentioned would do anything to improve circulation (vascular and/or lymphatic) over IR? Or would they both be similar in effect?

And would there be anything to the belief that vibration can cause the reaction within a cell to occur at a faster rate? Therefore, the creation of collagen might be accelerated. Or is this just wild speculation?

It’s not wild speculation, ultrasonic therapy does increase cellular processes, of which collagen building is counted.

Effect of Heat in Increasing the Range of Knee Motion After the Development of a Joint Contracture: An Experiment With an Animal Model

Mariko Usuba MS, PTa, b, Corresponding Author Contact Information, E-mail The Corresponding Author, Yutaka Miyanaga MD, PhDa, Shumpei Miyakawa MD, PhDa, Toru Maeshima PhDc and Yoshio Shirasakid

Objective

To compare the effects of 2 different heat modalities, infrared and ultrasonic therapy, on a knee flexion contracture.
Design

In vivo, experimental, controlled study involving a rat knee joint contracture model that was immobilized using a ligature in flexion for 40 days.
Setting

Collegiate research laboratory.
Animals

Ninety-three adult male Wistar rats.
Interventions

After remobilization, rats were assigned to 3 treatment groups: stretching only (S), stretching with infrared therapy (S+IR), and stretching with ultrasonic therapy (S+US). Six treatment sessions were given in 2 weeks.
Main Outcome Measures

The angle of maximum knee extension, wet-weight of triceps surae muscles, phase lag, and dynamic stiffness as mechanical responses were measured, and histologic study was conducted.
Results

Compared with the S group, both the S+IR and S+US groups exhibited a significant increase in range of motion (ROM) (P=.021, P=.008, respectively) and a tendency to decrease the phase lag, but there was no significant difference between the 2 heat-combined groups. There were no differences in the weights of the triceps surae muscles and in dynamic stiffness among the groups.

It sounds like Figo knows his shit. :homer:

I doubt it not! :angel:

My IR lamps keep breaking due to me not having enough hands, them always being angled wrong, me being relatively clumsy and they generally being of a weak build quality. I was searching the WWW to buy a third and hopefully final device when ultrasound peaked my interest, thus the starting of the thread.

Figo, perhaps you are in a position to answer my original question; is ultrasound safe for heating the penis for the purposes of PE? Would there be a significant difference in using a 1MHz and a 3MHz?

I just noticed something I missed in your thread:

The fact is I do want localized tissue heating, namely along the dorsal cord, since during stretching or hanging, it takes 100% of the force.

If it’s safe, since I can pick up an ultrasound for about the same price as a mountable IR lamp, I’d like to give it a shot, I can’t help it! As I said before, I’ve had trouble with IR light heating the skin to an unpleasant degree before the tough, deeper tissue is hot enough for the elongation I know I could get if I could just heat it up without burning my skin. My understanding is that ultrasound won’t burn my skin.

So, if they’re both in the same ball-park for deeper tissue heating, is there a reason not to try it?

It’s a shame FAR Infrared lamps are so expensive as IMO that would be the perfect solution for you.

I’m not familiar with far IR lamps; my understand is that NEAR IR lamps are more desirable since their wavelength is closer to that of collagenous tissue and thereby more effective. I have indeed been looking into near-IR LED lights since, according to my research, they seem to be the ultimate type of infrared therapeutic treatment.

This study found that, when tissue is pre-heated first with a heated gel-pack, temperature rises with ultrasound treatment were faster and peaked at a higher temperature.

Perhaps then, heating with IR or simple a heat-pack, prior to ultrasound, is not out of the question?
