The David Shoulder Solution revolutionizes the treatment of shoulder pain by using biomechanically optimized movements and a visual biofeedback system for guidance.

7 reasons why you should use a Medical Shoulder Device




Shoulder pain is
a massive problem

Shoulder problems cause the most sick leaves
of any musculoskeletal illnesses (15 days on average).
Shoulder pain is the most common musculoskeletal
disorder within people over 65 years (Taylor, 2005) and
its prevalence has tripled in the course of 40 years (Harkness,
2005). Every second person will suffer from shoulder pain
during their lifetime.

Today’s challenges

Traditionally, physiotherapy uses very simple tools like pulleys and rubber bands to rehabilitate shoulder problems. These methods are not measurable, trackable or repeatable and they are far from being biomechanically optimal.

For example, the widely-used rubber band exercises for outer and inner rotation of the shoulder have exactly the opposite loading curve compared to the muscles’ strength curve: the loading is at the highest at the end of the movement where the muscles are the weakest. This puts unnecessary stress on the joint while providing poor training effect.

Usually shoulder devices have been designed primarily to strengthen large upper body muscles but the causes for shoulder pain are nearly always elsewhere. Generally the problems are caused by weakening of the small stabilizing muscles of the shoulder joint. These rotator cuff muscles cannot be isolated with traditional fitness devices.

A change towards exercise therapy.

Today, more and more evidence is emerging which continuously prefers exercise therapy to surgery. Obviously, there are shoulder conditions that require surgical actions but for the most common problems such as shoulder impingement (or sub acromial pain syndrome as it is called nowadays) there is no scientific justification for surgical treatment.


More scientific studies

Shoulder impingement syndrome is one of the most typical shoulder problems. Surgery is a common treatment for this problem but recent study has shown that it offers no benefit over active treatment: “… arthroscopic acromioplasty has no good justification as a treatment for shoulder impingement syndrome, and it should therefore be abandoned as the standard treatment. Structured exercise treatment should instead be the basis for treatment.” (Ketola, 2016)

Pure isolation

With the David Shoulder Solution, internal and external rotators of the shoulder joint along with the scapular stabilizers can be activated safely and efficiently. Optimal joint angles and a supportive movement arm isolate the activation precisely to the desired muscles.

Pure isolation is essential, or else stronger internal rotators, like the pectoralis major, will do the work. When rehabilitating sore shoulders, a carefully designed resistance curve is absolutely crucial in order to perform the exercise in a controlled manner.

Guiding and motivation

In each device, a computer terminal guides and motivates the patients to follow exactly the given parameters prescribed in their individualized programs. Parameters include e.g. selected movements, adjustments, loading, range of motion, repetitions, movement speed, progression, session numbers and frequencies. These parameters are automatically designed and fine-tuned with the use of the cloud-based software and patients get immediate feedback on their compliance level.

Typical indications

The David Shoulder Solution suits patients suffering from prolonged
(sub-acute or chronic), recurrent, post-operative or post-traumatic
shoulder problems. Problems such as poor posture, frozen shoulder,
rotator cuff disorders, shoulder instability, acromioclavicular joint
disorders and osteoarthritis in the shoulder joints are also suitable
for rehabilitation through our exercise therapy solution.
