The ProStretch Shoulder Flex is a new product that helps people to regain and retain flexibility in their shoulder and rotator cuff muscles. The unique design of the Shoulder Flex allows for the user to apply leverage to the arm in a variety of positions to create tension on specific muscles. The tension translates into improved flexibility. This can be for regaining lost range of motion due to surgery or injury, or simply to maintain a normal range of motion for functional use. The Shoulder Flex also allows for a wide spectrum of users since it can be adjusted to accommodate virtually any level of flexibility. It may be used for internal and external rotation. Injuries to the shoulder and rotator cuff muscles are very common. In most cases, a combination of strengthening and stretching is recommended to fully recover. However, stretching often requires the assistance of another person to help provide the necessary leverage to the injured area. The Shoulder Flex allows the user to stretch the muscles safely and effectively without the need for large equipment or another person. This is a great improvement, which will also assist in recovery, even from surgery. The ability for the user to apply controlled tension in a variety of different positions and accommodate for continued range of motion improvement is truly unique to the Shoulder Flex. Although the Shoulder Flex has been shown to be very safe to use, it is always recommended to get the approval of a medical professional before using it for rehabilitation. No other product on the market today has the combination of ease of use, portability, safety, and most importantly, effectiveness, that the Shoulder Flex has in its wheelhouse. People can now effectively rehabilitate and stretch in the comfort of their homes with a quality product usually only found in a clinical or medical environment. The ProStretch Shoulder Flex can help people get back to a functional and pain-free lifestyle.
