Case Study: Misdiagnosis Prolongs Symptoms of Adhesive Capsulitis, aka Frozen Shoulder Syndrome

Our Patient


Our patient is a middle-aged male complaining of chronic shoulder pain and limited shoulder joint range of motion.

The Challenge


The patient had been treated at another clinic, where he was diagnosed with rotator cuff tendinopathy and related postural issues. He was provided with physical therapy, with no success in alleviating his shoulder pain.

Our Diagnostic Approach


Clinical Exam

The clinical exam included a review of health history, a physical exam, and standard testing for shoulder strength and range of motion.

Diagnostic Ultrasonography

We used high-resolution ultrasound imaging to examine the structures surrounding the shoulder joint, and did not find any indications of rotator cuff tendinopathy or fascial adhesions. We concluded that the patient was in the early stages of adhesive capsulitis.

Our Treatment Approach

We treated the shoulder using defocused shockwave therapy and INDIBA radiofrequency therapy. We combined those therapies with home exercises and stretches, and we were able to improve the patient’s shoulder range of motion by 80% within eight weeks.

 

Discussion


Adhesive capsulitis – aka frozen shoulder syndrome – can last for a year or longer, and the earlier the treatment, the more successful the results. Conventional treatment for frozen shoulder syndrome is physical therapy, which is rarely effective in restoring shoulder range of motion.

In this case, the patient was incorrectly diagnosed and treated, prolonging his pain and disability. Consequently, early treatment that would normally produce results after two weeks was delayed, extending the patient’s recovery period to eight weeks.

Accurate diagnosis and early treatment leveraging new technologies can dramatically accelerate recovery from frozen shoulder syndrome, quickly reducing the patient’s pain and discomfort, and improving their quality of life. At NYDNRehab, we feature advanced technologies and expertise that are rarely found in traditional physical therapy clinics.

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
