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 worldwide.
Shoulder problems cause the most sick leaves of any musculoskeletal illness, about 15 days on average. Shoulder pain also is the most common musculoskeletal disorder in people over 65 years (Taylor 2005), and its prevalence has tripled in the course of 40 years (Harkness 2005). One out of two people will suffer from shoulder pain sometime during their lifetime.
Traditionally, physical therapy 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 the highest at the end of the movement where the muscles are the weakest. This puts unnecessary stress on the join and, at the same time, provides a poor training effect.
Usually, shoulder devices have been designed primarily to strengthen large upper body muscles but the causes for shoulder pain are almost always elsewhere. Generally, the problems are caused by the 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 that continuously prefers exercise therapy to surgery. There are, however, shoulder conditions that require surgical actions, but for the most common problems, such as shoulder impingement, or subacromial pain syndrome, there is no scientific justification for surgical treatment.
One of the most common shoulder problems is known as shoulder impingement syndrome. Though surgery is the standard treatment for this problem, a recent study has shown that it offers no benefit over active treatment. For example, “(…) 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).
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 stronger internal rotators, such as the pectoralis major, will do the work. When rehabilitating sore shoulders, a carefully designed resistance curve is crucial so that the exercise can be performed in a controlled manner.
Guiding and motivation
In each device, a computer terminal guides and motivates patients to follow exactly the given parameters prescribed in their individualized programs. Parameters include, for example, 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 cloud-based software and patients receive immediate feedback on their compliance level.
The David Shoulder Solution suits patients suffering from prolonged
(sub-acute or chronic), recurrent, post-operative or post-traumatic
shoulder problems. Other 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.
