How does Therapeutic ultrasound work?
The Secret of Ultrasound Therapy
Therapeutic Ultrasound - a Quick Overview
is a method of stimulating tissue beneath the skin's surface using sound waves. The sound waves are very high frequency, typically between 800,000Hz and 2,000,000Hz, and can penetrate up to 4 inches below the surface of your skin. The sound cannot be heard by humans or animals (humans can only hear sounds up to about 20,000Hz). This very high frequency sound affects very small molecules and cells in the body, and actually causes them to move around.
The way ultrasound waves are transferred into the body is a function of many factors. The frequency of the ultrasound waves is actually opposite to how deep they will penetrate the body. For example, a 1MHz ultrasound will penetrate about 4 inches below the skin, whereas a 2MHz ultrasound unit will only penetrate about 2 inches. While a low frequency means deeper penetration, using too low of a frequency will mean that the waves are too wide to properly move the molecules. For therapeutic applications, 1MHz is the optimal frequency for both effectiveness and penetration.
Power output is another significant factor. It is measured in watts per square centimeter. The higher the power, the more energy is transferred into the body. If too high a power output is used and an ultrasound unit is left sitting still on the body, it is possible to burn the tissue beneath the skin. While several professional ultrasound machines are capable of these high powers, your medical practitioner will typically use a lower power setting, below 1 watt per centimeter squared. More power is not necessarily better. Though some therapists may use higher powers to speed up ultrasound treatments, it is actually more effective to use a lower power setting for a longer period of time to achieve the optimal healing effect.
The power output rating is often broken down into two separate units: peak intensity and average intensity. Peak intensity can be thought of as how tall the sound waves being sent into your body are. The waves need to be large enough to affect the tissue and provide the desired therapeutic effect. At the same time, your body tissue needs breaks between groups of waves to cool down. So, Ultrasound machines actually send the waves in "pulses" (groups,) giving your body a vibrate-rest-vibrate-rest effect. The average intensity is a measure of how much energy is transferred over a period of vibrate-rest cycles.
When applied directly to the skin, an ultrasound device cannot effectively transfer the sound waves into the body. To make it work properly, a conductive medium is required - ultrasound gel. The gel simply makes it possible for the sound waves to travel from the unit head into your body. Ultrasound treatments without gel is ineffective, and can damage the ultrasound unit.Ultrasound machines provide a Total Power Output rating. High power units are typically used with large applicator heads to treat larger areas of the body. The important measurement part of ultrasound is the watts per square centimeter mentioned above, not the total unit power. Again, it is more effective to treat the affected area more frequently and for longer periods of time, using a lower power setting.
What Does it Do?
The heating and massaging effects of Therapeutic Ultrasound have two primary benefits. First, it increases blood flow to the treated area, which speeds the healing process. Second, it reduces swelling and edema, which are the main sources of pain.
Ultrasound can also be used to administer therapeutic medicines into the body, through a process called phonophoresis. In such a case, there are 3 benefits to a treatment, the first two from the massaging effect of ultrasound discussed above, and the third from phonophoretically administering the medication. Ultrasound treatments with Phonophoresis are rapidly becoming more popular than Ultrasound Therapy alone, due to the added benefits.
For most injuries and ailments, a cycle of ultrasound therapy should optimally consist of 5-10 minute treatments, repeated 2-3 times per day for the duration of the healing period- this routine will mean fast, efficient healing, allowing you to get back to your normal life without being in pain. This surprises many people who have gone for single treatments in clincs only 2 or 3 times each week. The clinic approach, while providing the benefits of ultrasound therapy, simply become too expensive and too inconvenient.
Ultrasound Gets Rid of Inflammation Fast!
When you have a tendinitis or tenosynovitis injury, the area becomes inflamed as the damaged tissue cells release toxins. These toxins cause the injured area to be tender to touch, red, and sore to move. As the toxins and damaged cells accumulate, blood vessels become blocked and fluid gathers... resulting in swelling and pain. This is very much like the effect a dam has on a river - the flow is stopped and the fluid just builds up.
Ultrasound Treats Your Painful Scar Tissue
In most cases of a tear, strain, pull, or cartilage degeneration, scar tissue begins to form at the injury site, binding your tissues together abnormally.
Unlike healthy tissue that works like a stretchy elastic band, scar tissue is tough and inflexible. Most of us know of someone that just can't seem to recover from a soft tissue injury - a good example is a runner that has injured their achilles tendon: the injury stops hurting so they start running again, and the scar tissue from the old injury just prevent the achilles from flexing properly, so they keep straining it time after time. In fact, 90% of runners that have injured their achilles will reinjure their achilles again... this is what scar tissue can do - it turns a short term injury into a long term recurring injury.
Scar tissue limits the range of motion in your tendon (and attached muscle), greatly increasing the chance of re-injury (by overstraining), causes pain when stretching and can leave you vulnerable to a life time of chronic inflammation and pain.
How Blood Flow Stimulation Therapy Works
Your body can heal itself! In fact, your body started healing itself the moment you injured your tendon and it's the blood in your body that makes it all happen.
Your blood is the transport mechanism for everything that is good inside you. It carries oxygen, nutrients, water and antibodies.
Proper blood flow to your tendon is essential to healing. Unfortunately, when you injure your body, you stop moving and the swelling sets in. That means your vital blood flow can be reduced to a trickle!
It will seem weird for you to read this, but there are a LOT of people out there that do not understand how fast a Freezie Wrap can get the swelling / inflammation of an injury under control... fast! Only once the inflammation is reduced can a person start to deal with their actual injury and pain - and this is where the BFST effect from an HealthFlex blood flow wrap really starts to shine!The MISSING Piece of the Puzzle....
where SO MANY get it WRONG!
Swelling and tendon inflammation is the effect of your body responding to an injury. A lot of pain will probably disappear as the swelling disappears, and many people make the wrong assumption that their tendon, muscle or other soft tissue injury must be healing as most of the pain is gone. Once you have reduced the swelling with cold, remember that your injury is still there.
This is a critical time! Once the inflammation is gone it may feel like you can return to your regular sports, hobbies, exercise or other activities - but your tendon (and possibly your muscle tissue) is in a weakened state, unstable, and still injured. Even the slightest movement in the wrong direction can worsen the injury and increase the swelling yet again. Most "weekend warriors" and amateur athletes will start going back to what they were doing before they got their tendinitis, and that is where they get it wrong - professional athletes know that the injury is still there and needs to be dealt with before resuming their activities 100%!BFST - Accelerated Healing Power for Your Tendonitis
Have you seen what happens when you add water to a flower wilted from drought? In essence, an injured tendon is much like a "wilted" flower; your body wants to heal its injury, but needs lots of nutrients to do it.If you want to heal quickly, you need to keep your blood moving and that's where BFST®, comes in. What is BFST? It's a substantial increase in the flow of blood to your injury location without the need to exercise the area. This is what the HealthFlex wrap does... you can really feel it work!
Blood brings new life to your cells by delivering healing nutrients and oxygen that are vital to your tissue. In addition, the blood carries away toxins and cellular waste cleaning the area and healing it faster. Without a good supply of blood, your tendon simply won't heal properly.
In order to get maximum blood flow to your injury, you need to help your body stimulate blood flow. BFST(blood flow stimulation therapy), is the fast, easy and pain-free way to increase blood flow and speed healing. It is the key to dealing with your tendonitis injury properly.
Within moments of applying an BFST Wrap to your injured tendon or muscle, you can feel the healing sensation and the increase in blood flow.
During a treatment, and for quite some time after you finish, your injured tendons, ligaments, bursae and muscles will experience increased blood flow even though your body is at rest. It's a soothing sensation and extremely effective.
With BFST your injury is constantly being fed with healing, nutritious, oxygen and energy filled blood. This is exactly what your body needs to heal.To order it click the contact me tab.
