FLEXTEND® provides a gentle, active stretching action of the flexor muscles and active strengthening of the extensor muscles that cross the finger, wrist and elbow joints. This system also actively stretches and strengthens the supinator / pronator and radial / ulnar deviator groups.
When used on a regular basis, FLEXTEND® effectively lengthens the short, restrictive, overdeveloped muscle groups while simultaneously strengthening the opposing underdeveloped muscle groups in order to create more normal strength/length ratios between agonist and antagonists alike. By creating a balance between the muscle and tendon structures in the hand and arm, you can often greatly reduce or eliminate the abnormal pressures within and around the finger, hand, wrist and elbow structures, allowing the body's natural healing processes to function.

FLEXTEND®-AC Upper Extremity Training System:
The FLEXTEND®-AC is used for Performance Enhancement, Thoracic Outlet Syndrome, Rotator Cuff Injuries, Joint Instability, Postural Disorders, Impingement Syndrome and many other upper extremity disorders by providing more than 50 therapeutic upper extremity exercises in one easy to use product.

The FLEXTEND®-AC corrects the strength / length imbalances of the entire upper extremity, but specifically focuses its effects on the shoulder girdle due to its complex structure and vulnerability to injury. Creating strength equality between the muscle groups within and around the shoulder helps to reduce the impingement of underlying nerves and blood vessels that are often the root cause of painful and debilitating symptoms.

FLEXTEND®-AC also targets many other specific areas of the upper extremity, utilizing a variety of physician and therapist recommended exercises and training programs for the fingers, wrists, elbows, forearms, biceps, triceps, chest and back.
