Clinical Facts

Definition and development

Tennis elbow is an inflammation of the outer tendons and tendon insertion, golfer's elbow is an inflammation of the inner epicondylus and the inner tendon insertions

Tennis elbow, golfer’s elbow, mouse elbow. All of the are colloquial names for the epicondylitis. The used terms depend on the muscles and tendon affected.

In the outer tendon, the radial epicondyle, the common name is tennis elbow.
At the inner tendon, the medial epicondyle it is called the golfer’s elbow.

The correct medical term for the tennis elbow is “epicondylitis humeri radialis“, the golfer’s elbow has the terminology “epicondylitis humeri ulnaris“. Ulna and Radius are the latin terms for ell and spoke.

The name tennis elbow, respectively golfer’s elbow by the way results due to the fact that many tennis player or golfers are being confronted with the epicondylitis during their career as an athlete. The impact of countless strokes, a possible wrong racket or club position and else lead to the injury being widely spread among sportsmen.

A newer term is the mouse arm, as more people are exposed to one-sided burden of work on the computer.

Just like the tennis elbow and golfer’s elbow, especcially the mouse arm is connected to the formation mechanism of the Repetitive Strain Injury-Syndrom (RSI-Syndrom) (Reference: Wikipedia)
Basically, however, the epicondylitis can occur in all activities that strain the arm, even a wrong sleeping position can trigger the injury.

That is why the vast majority of patients suffering from an “tennis” or “golfer’s” elbow have never played tennis or golf in their entire lives.

Spread and disease duration

There are many case studies, dissertations and thesis regarding the prevalence or incidence of the epicondylitis, but unfortunately none of those is presenting uniform results or conclusions. The solely consensus of these publications is, that there are no reliable valid numbers at the moment. That is why we are only going to present some excerpts of a few sources from our huge data collection and library, based on the status of current knowledge.

Subsequent to back problems, the epicondylitis is amongst the most widespread health problems in industrialized nations.
The prevalence (frequency of disease per year) is an estimated 1,5% to 6% of the general population. Thus up to4,8 million people suffer from the epicondylitis solely in Germany.

The incidence (new diseases per year) is even estimated somewhere between 1% to 9%. It is assumed, that only roughly 50% of the affected persons seek medical advice at all, or aborts therapy after some failures in treatment.

The epicondylitis is most common in the age class between 45 and 54 and the “tennis elbow” (radial epicondyle) is around five times more common than the “golfer’s elbow”, meaning the injury/inflammation at the medial epicondyle.

There are several occupational groups, in which the incidence of the injury is markedly higher:
Masalo Pfeil Forest workers: up to 29%
Masalo Pfeil Montage automotive industry: up to 20%
Masalo Pfeil Cooks: up to 10,5%
Masalo Pfeil Plastic surgery: up to 13,1 %

Disease duration
In general it is assumed that the disease duration averages from 6 to 48 months. From a disease duration of 6 months onwards, the epicondylitis is classified as being a chronic disorder.

Loss of working time / recurrence
Based on statistics of the CSST, Quebec (2009), the average loss of working time is about 83,7 days per patient and the risk of recurrence is about 10,6% for certain professional groups.

Now you see that the epicondylitis is pretty common and widely spread and may need a long time to heal completely.

Tennis elbow? Golfer’s elbow? What is that actually?

Microcracks at the tendon insertions - epicondylitis

With each movement of the arm, fingers or wrist tensile forces of the forearm muscles act on the tendon attachments (Epicondyli) at the elbow. Unusually high loads, strenuous or repetitive movements of the arm can lead to microcracks in these tendons and they may become inflamed. (Reference: Netdoktor), (Reference: Wikipedia)

With increasing age, chances grow that the injury / illness will be chronic, because starting at age of about 40, the production of collagen automatically decreases and tendons are significantly less elastic and resilient. (Reference: Gelenk-Doktor)

This leads to severe pain in the elbow area and it may hurt under heavy loads as well as in hibernation, even during sleep. Origin is either an inflammation or an injury.

The logical solution against Epicondylitis

Once being diagnosed with an epicondylitis by a physician, the first prescribed treatment of is the cortison injection.
As this may help against the inflammation it does not fight the causes of the epicondylitis – physical forces.
To reduce these forces, additionally the common clamps and clasps are decreed.
These braces, claps, splints or orthoses are all working with the exact same mechanism of action: Compression of the muscles.

The Masalo® Cuff works very successfully with a completely unique and new mechanism of action.

The muscles and tendons of the forearm are “mounted” to the tendon insertions at the elbow.
With each movement of the arm, fingers or wrist tensile forces of the forearm muscles act on the tendon attachments (Epicondyli) at the elbow. Unusually high loads, strenuous or repetitive movements of the arm can lead to microcracks in these tendons and they may become inflamed.

You can easily see these tensile forces with your own eyes:
Put your arm on a table and simply move your fingers. You will instantly see the movement at the outer epicondylus.
Or just close your hand and make a fist (repeatedly) and reopen your hand. If you now take your other hand and gently touch your lower part of the forearm in the area of the tendon insertions, you will feel how your muscles – the tensile forces – work.

If tensile forces are the main cause for the injury and if every single movement of the arm may even aggravate the condition, wouldn’t it be logical to apply a counter-force to the area affected?


As soon as this counter-traction deflects and intercepts the tensile forces, shouldn’t this lead to immediate and noticeable pain relief as well as a significant support of the healing process?

Tensile forces? Counter-force!

Masalo® Cuff does exactly this by generating a counter-traction on the extension of the arm, it causes a discharge of the affected area and the arm can be used normally again.

With the Masalo® Cuff attached, the arm remains flexible and the muscles are permanently stretched and massaged, which reduces the risk of aggravation and incidence. The Masalo® Cuff can be worn as a preventive measure and in an acute or chronic epicondylitis.

This brand new tennis elbow treatment fights the real cause of the epicondylitis and its logical machanism of action is the ideal alternative or additional treatment when suffering from an epicondylitis.
The effect of the cuff can be felt instantly.

Main cause of the epicondylitis

Just like the intensity of pain differs from person to person, the trigger of the epicondylitis as well is very various.
Active people like craftsmen, office-employees (working at a PC: mousearm), warehouse workers, retail salesmen and saleswomen, homemaker, athletes, hobby gardeners etc. are often affected. Even knitting, raking or snow shoveling can trigger the injury.

Very often the epicondylitis is caused by exceptional or unusual and unfamiliar activities such as moving, spring-cleaning, construction works, special tasks at the job, slipping on the ice (and the involved arm support to prevent falling) etc.

Once the injury is triggered and the microcracks and microtears occur at the tendon insertions, they are strained and exacerbated by almost every simple all day activity such as shaking hands, brushing teeth, combing hair, setting the table or every arm and hand use in sports etc.
The vicious circle begins and the tensile forces “do their work”.

By the way – both tennis elbow and golfer’s elbow have the same causes. The actual trigger-activity is then the decisive factor whether the injury occurs at the medial or the radial epicondylus.

The causes of the tennis elbow or golfer's elbow vary highly - the Masalo cuff is ideal for sports, work and everyday life.

With the Masalo Cuff attached, the affected area will not only be relieved immediately and permanently by the counter-traction, additionally, with every movement of the arm the forearm muscles are being massaged and relaxed, too. All activities at home, during leisure time and work can be fully executed, the muscle remains strong. The arm can still be fully extended with the applied cuff.

Impacts of an epicondylitis

For those patients suffering from tennis elbow or golfer’s elbow, the diagnosis epicondylitis often means a significant loss of the quality of life and a painful cuts in many areas of life.

Depending on the individual progress and manifestation of the injury/disease even the most simple everyday life activities like lifting a mug, driving a car etc. go along with severe pain.

The main symptom at this is a stabbing pain in the elbow area which may, depending on the intensity, even radiate towards shoulder and/or hand. Depending on whether suffering from a tennis elbow or a golfer’s elbow, the pain occurs either on the inner or the outer side of the arm when rotation the hand etc.

So instead of just fighting the pain, why not simultaneously fight the cause?
Isn’t that the best and simply logical solution?

How does the Masalo® Cuff work?

The leather cuff is placed around the forearm and a leather strap comprises the upper arm. Now, with every extension a counter-traction is exercised, which attenuates and sometimes even completely neutralizes the tensile forces acting on the tendon whereby elbow and tendons are relieved. Despite relief of the forearm, the muscles are not weakening, because the arm can still be used normally. Due to the unrestricted blood flow the healing process may also be promoted.

The Masalo® Cuff can be worn preventively and provide immediate help with acute and chronic epicondylitis. The brace can and should if possible be initially worn (for about 14 days) for 24 hours, permanently – even at night – the tendons are relieved and sleep due to uncontrolled movement is not disturbed. If worn at work or in sports, the power development can be promoted.

As the experience of other sufferers show, with the Masalo® Cuff it is even possible to exercise weight training pain-free despite epicondylitis. When playing tennis, experience has shown that the handling of the racket is improved. The stabilization of the elbow leads to an increased power. Some even have benefited from the Cuff in other sports such as javelin, handball, and volleyball as well as golf in particular, where the cuff functions as a “guide” for the arm, improving the continuity of the swing for mid-handicappers especially.
