When used on a regular basis, FLEXTEND® and the FLEXTEND®-AC effectively lengthen short, restrictive, overdeveloped muscle groups while simultaneously strengthening long, weak, underdeveloped muscle groups in order to create more normal strength/length ratios between agonist and antagonists. By creating a balance between the muscle and tendon structures in the finger, hand, wrist, forearm, upper arm and shoulder, you can often greatly reduce or completely eliminate the abnormal pressures within and around these joints and allow the body's natural healing processes to function.

University and Private Testing has shown that the FLEXTEND® and the FLEXTEND®-AC stretching and strengthening programs can alleviate or greatly reduce the symptoms of individuals suffering with Repetitive Strain injuries, including Carpal Tunnel Syndrome, Trigger Finger, Guyon's Syndrome, AC-Injuries, Thoracic Outlet Syndrome and many other musculoskeletal disorders of the upper extremity.
