Trigger Finger / Trigger Thumb

The most common symptom associated with Trigger Finger is a "snapping" or "locking of the finger or thumb into the palm of the hand. These sensations are experienced due to an adhesion or nodule that has developed on the tendon, most often resulting from scar tissue that has developed due to micro tears of the tendon.

The nodule / adhesion generally passes through the pulley system (tendon sheath) as the finger or thumb is flexed, but as it tries to pass through the pulley system via extension, it becomes stuck. In more severe cases, the finger has to be manually pulled back into the extended or straight position.

In many instances, Trigger finger is caused by repetitive or forceful flexion of the fingers or thumb, a result of repeated trauma from power tools or long hours grasping a steering wheel or other objects. Other contributing factors include medical conditions that cause changes in tissues, such as rheumatoid arthritis, gout or diabetes.

Performing corrective exercises with FLEXTEND® / RESTORE™ can reduce scar tissue on the tendon as well as help stretch and thin the tendon, allowing it to move freely through the pulley system. This training system is very simple and effective therapy, taking just minutes per day.
