Who was the first person to use laser therapy?

His name is Dr. Fred Kahn. He graduated from medical school at the University of Toronto. He became a general surgeon and ultimately chief surgeon at a huge mining operation in northern Ontario. He went to Massachusetts General Hospital to study vascular surgery, then to Texas to study at Baylor with one of the finest surgeons in the world, Denton Cooley, who performed one of the first heart transplants. In California he practised vascular and general surgery, operating on abdominal aneurysms, doing bypass procedures and clearing clogged carotid arteries. He was a consulting surgeon to the U.S. military. As lead physician he went on to establish a 250-bed hospital, becoming chief of staff and then chair of the department of surgery.

What happened to him, why did he change his carrier?

In 1986, Dr. Kahn, an avid skier, had damaged his shoulder and it became a chronic problem. He had skied the great mountains, and got a serious rotator cuff injury. For 2 years it had been difficult for him to do any physical activity. Steroid injections didn’t help. Traditional medical options all pointed to the necessity of surgical intervention. Dr. Kahn, however, determined surgery would add an additional trauma and inhibit the healing process. This led him to focus his interest and energy on the healing potential of Low Level Laser Therapy. Starting in 1988, he pioneered the development and clinical application of laser therapy systems, which continues to this day.

Dr. Kahn founded Meditech International in 1989 and has an active role as President and CEO of the company. Meditech International is a company dedicated to utilizing low intensity laser therapy to resolve many standard, complex and challenging diseases.[3] As a result of this therapeutic process, many pathologies are effectively resolved, eliminating pain and other symptoms. The company has developed a series of laser therapy systems as a clinically proven, non-invasive and safe alternative to many traditional therapies. Moreover, the technology consistently produces optimal patient outcomes.

Products are designed for both healthcare professionals and patients at home or while travelling. In addition, Meditech International operates two clinics in the Greater Toronto Area to treat patients with an extensive number of clinical problems on a daily basis. The company sells its professional devices to many practitioners, including chiropractors, physicians, physiotherapists, naturopaths, osteopaths, RMTs, dentists and veterinarians. Personal systems are sold to a growing number of patients who are unable to obtain professional care on a regular basis.

Dr. Kahn leads a team consisting of basic researchers, clinicians, and a variety of engineering disciplines to design and manufacture devices and develop both standard and customized protocols to treat musculoskeletal disorders, including arthritis, sports injuries, spinal problems, trauma, wounds, vascular problems, etc.

He has worked with clinicians and engineers to develop standard protocols to treat musculoskeletal disorders including arthritis,[4][5][6][7] herniated disc,[8] wounds,[9] TMJ,[10]shoulder tendinopathies,[11] elbow tendinopathies,[12] neck pain[13] and back pain.[14]. The technology is highly effective in many instances where conventional therapies do not provide resolution of the existing disease process and the accompanying symptom complex.

Piriformis Syndrome

Several people think they have a lumbar spine problem or nerve problem on their leg. Maybe not. Sometimes the problem is lower down and deeper but the symptoms are very similar to these.

Symptoms of piriformis syndrome include tenderness and pain in the buttock area, accompanied by sciatica – like pain, numbness and weakness that runs down the back of the thigh, calf, and foot.

Pain from piriformis syndrome is often worse when walking up stairs, after sitting or while walking or running.

What is that muscle and where is it?

The piriformis is a small muscle located deep in the buttock, behind the gluteus maximus. It runs diagonally from the lower spine to the upper surface of the femur, with the sciatic nerve running underneath or through the muscle.

The piriformis muscle helps the hip rotate, turning the leg and foot outward. As a result of overuse, injury, or strain, the piriformis muscle can tighten, swell, or spasm. Sports that involve repetitive forward movement of the legs, or problems in surrounding joints like the sacroiliac joints are typical causes of piriformis syndrome.

The location of the piriformis muscle near the sciatic nerve means that when the piriformis muscle is irritated or injured, it can affect the sciatic nerve as well. That is when people have the same symptoms as with the lumbar spine problem.

In the attached picture you can see how deep both this muscle and the nerve are in the body. As opposed to massage, laser beams can get deep down into the tissues and reach the sciatic nerve and the piriformis muscle and treat the inflammation.


The temporomandibular joint (TMJ)

The temporomandibular joint (TMJ) is a joint in the jaw. TMJ disorder is a painful condition.

Many people describe swelling (caused by inflammation) on the side of the face as an audible popping and clicking sound when yawning or chewing and closing the mouth even if they can’t close their mouth.

Sometimes the cause is overwork or if you’re under the stress and you grind and clench the teeth.

What the dentist recommend is soft food, not to open your mouth too wide or to wear a mouth guard at night. With these the problem usually settles down.

But sometimes it just gets worse and there is nothing to do with these pieces of advice. Why?

A flat neck can cause TMJ disorder too.

TMJ patients suffer from jaw misalignment pain. Misalignment means the cervital vertebra or the skull isn’t in the right position.

A normal neck has a gentle curve to it and keep the head in the middle.

Nowadays many people sit all day, which has changed spine position and the neck is getting flat. The change of the neck position has changed the head and joint position too and more symptoms arise, like head and ear ache and also neck pain.

Soft laser therapy can reduce inflammation and stop the pain. It can find the trigger point on the neck, make the muscle relax and take the pressure off the TMJ and help the neck move back to the right position. Patients can stop being on a soft diet and they can quickly get back their normal life.
