Recently I have seen alot of hand held portable ultrasound devices for sale and I would like your opinion on wether or not they are of any use. I would like to know what the minimum specifications to look for eg. hertz and all that stuff that you would look for. Are they any good for knee pain, hand soreness, ligaments and muscles? Apparently Josh Hansen was getting some work done on his broken hand by Doctor G. with some type of machine. I would realy appreciate your advice on this one. Best Regards Gary M

I asked my associate therapist/DC and here's his response:

Ultrasound works great for many conditions, I use it on everything from muscles strains, trigger points, or deeper structures, such as knees. Therapeutic ultrasound frequency (Waveform) used is, 0.7 to 3.3 MHz ( The lower the number the deeper penetration). Most units sold offer a 1MHz setting, which I like to use because it penetrates deeper. Ultrasound must always be moved constantly in a circular motion or it will burn the Periosteum (outer layer of the bone). Maximum energy absorption in soft tissue is about 3 inches, so you would not want to use the 1 MHz (deeper) setting over areas of decreased tissue, like the hand. Intensity decreases as the waves penetrate deeper. They are absorbed primarily by Connective tissue, Ligaments, Tendons and scar tissue. I believe most places won't sell a unit unless you have an active state license, (PT, DC, DO). When I bought mine I had to give my license number. Hope this helps.

Any therapeutic ultrasound device should only be used by a licensed professional who has been trained to use the device. I agree with the previous post that they are an integral part of many PT and chiropractic practices. However, there are dangers if they are missed used or used on the wrong area or with the wrong settings. Therefore, I disagree with trying to purchase or use one unless you are properly trained and credentialed.

Thank you very much for your reply to my question. Can you please tell me if the ultrasounds sold on ebay and other sites like it are of any use or are they just a scam? They are usually pretty cheap,any where from $40 to $180 and are said to be 1MHZ. I think alot of people would like some professional opinions before spending good money on one of these things. Kind Regards Gary M

Yup, forgot to post it:

From Brian Griffith, the PT/DO at my gym:

More than likely this device does not offer the true current as advertised. These machines must be approved medical devises and the company should ask for a license number when buying it. For instance, an approved Ultrasound machine in the U.S. located in a therapy setting costs thousands of dollars for a reason. The units are tuned, tested and must offer a true 1 MHz setting. As a side note, if Ultrasound is done wrong you can actually burn the outer layer of the bone called the Periosteum.
