Ultrasound and Physical Therapy: An Introduction

Written by Jim Doree

Ultrasound is a therapeutic modality that has been used by physical therapists sincerepparttar 1940s. Ultrasound is applied using a round-headed wand or probe that is put in direct contact withrepparttar 148873 patient's skin. Ultrasound gel is used on all surfaces ofrepparttar 148874 head in order to reduce friction and assist inrepparttar 148875 transmission ofrepparttar 148876 ultrasonic waves. Therapeutic ultrasound is inrepparttar 148877 frequency range of about 0.8-1.0 MHz.

The waves are generated by a piezoelectric effect caused byrepparttar 148878 vibration of crystals withinrepparttar 148879 head ofrepparttar 148880 wand/probe. The sound waves that pass throughrepparttar 148881 skin cause a vibration ofrepparttar 148882 local tissues. This vibration or cavitation can cause a deep heating locally though usually no sensation of heat will be felt byrepparttar 148883 patient. In situations where a heating effect is not desirable, such as a fresh injury with acute inflammation,repparttar 148884 ultrasound can be pulsed rather than continuously transmitted.

Ultrasound can produce many effects other than justrepparttar 148885 potential heating effect. It has been shown to cause increases in tissue relaxation, local blood flow, and scar tissue breakdown. The effect ofrepparttar 148886 increase in local blood flow can be used to help reduce local swelling and chronic inflammation, and, according to some studies, promote bone fracture healing. The intensity or power density ofrepparttar 148887 ultrasound can be adjusted depending onrepparttar 148888 desired effect. A greater power density (measured in watt/cm2 is often used in cases where scar tissue breakdown isrepparttar 148889 goal.

Ultrasound can also be used to achieve phonophoresis. This is a non-invasive way of administering medications to tissues belowrepparttar 148890 skin; perfect for patients who are uncomfortable with injections. With this technique,repparttar 148891 ultrasonic energy forcesrepparttar 148892 medication throughrepparttar 148893 skin. Cortisone, used to reduce inflammation, is one ofrepparttar 148894 more commonly used substances delivered in this way.

The End Of The Road

Written by Patrick Mathieu

Last week I was driving along one ofrepparttar major highways around Toronto. I had some good music playing on my stereo andrepparttar 148844 weather was wonderful.

I am always a careful driver, so my attention was focused on my driving, but my thoughts were elsewhere. Suddenly, I noticedrepparttar 148845 sign warning thatrepparttar 148846 highway was coming to an end just ahead. Only then did I realize that I had missed my exit!

Has that sort of thing ever happened to you?

This situation is an excellent illustration of why I considerrepparttar 148847 message of "Mindful Awareness" to be so very important. Consider that all of us are traveling downrepparttar 148848 highway of life. Each of us has an idea of which route we would like to be taking, but we must be constantly mindful or else we risk missing our turning points.

Sometimes a missed turn can be fixed by taking another turn and circling back. Sometimes an even better route presents itself. But sooner or later everyone will find themselves atrepparttar 148849 end ofrepparttar 148850 highway and many people will be unprepared forrepparttar 148851 sudden ending ofrepparttar 148852 journey. "I was so sure thatrepparttar 148853 highway was longer than this!" they'll say.

My speaking, my book, my coaching and these weekly Mindful Moments all have a common goal. The entire point of my message torepparttar 148854 world is to ensure that you don't reachrepparttar 148855 end of your highway only to look back and say:
