Trusted by Medical Professionals to Enhance Patient Outcomes

Enhancing patient outcomes depends on consistent, correct rehabilitation, both in the clinic and at home. The ProStretch® Shoulder Flex is specifically designed to improve compliance by giving patients a safe, effective way to continue therapy independently.

Unlike improvised at-home methods, the Shoulder Flex provides controlled leverage without the risk of hyperextension, ensuring proper movement patterns and reduced risk of reinjury. This allows patients to confidently perform prescribed stretches and strengthening exercises between visits, reinforcing the work done under your care.

With the Shoulder Flex, you can trust that your patients are maintaining progress, supporting faster recovery timelines, greater long-term mobility, and improved overall satisfaction with their rehabilitation process.

Andres Story:

"Unfortunately, in June, I sustained a massive rotary cuff injury (labrum damage, and three torn tendons). After my surgery in July, I wanted to make every effort to recover as safely and quickly as possible. However, reality took over. I began seeing slow progress, due to obvious challenges with flexibility and tightness. Per the surgeon, the injury was the most severe he had seen.

I completed some research and came across the ProStretch Shoulder Flex. I may have only had your product for a few weeks, but it has worked wonders. When I first received the ProStretch, I could barely do one. I showed my workmen's comp PT staff, and they were impressed. I gave them a brief demonstration, showed them the pamphlet, and gave them the website. Now, I can do three out of the four!!! This has been the best purchase I have made with the best results. The discomfort and pain have been decreasing daily while my flexibility has been improving! I am targeted to be released from therapy a month early!"

Regain Flexibility and Improve Mobility

Traditional rehabilitation methods limit the patient to only stretching when they visit their physical therapist. With the use of the portable ShoulderFlex and integrating guided active stretches, patients can take charge of your own recovery journey. The carefully designed stretches in the included manual are tailored to facilitate shoulder rehabilitation, ensuring patients are using correct form.

The key to successful rehabilitation lies in the proper execution of exercises, and that's precisely where the ShoulderFlex shines. By providing step-by-step instructions, patients can confidently perform their exercises with precision and accuracy. This not only enhances the effectiveness of their rehabilitation but also minimizes the risk of potential setbacks or injuries.

Its push-button design accommodates various arm sizes, providing an optimal, comfortable stretch. Lightweight and portable, it can be conveniently used anywhere, every day.
