The Carter Cuff exercise device is an armband designed for use by a person with a hand prosthesis or by a person whose hand function is temporarily or permanently impaired. The Carter Cuff allows its wearer to perform numerous exercises that would otherwise be impossible by providing connection to to exercise machines and free weights that would otherwise require the wearer to grasp a handle or operational position of an exercise machine with his or her hand, and an optional shoulder harness can be attached to the armband for additional stability. The Carter Cuff provides its wearer with the opportunity to create a muscularly and neurologically balanced and symmetrical body, especially upper body.

The first Carter Cuff was manufactured in 2009 and refined and developed using over a dozen prototypes. During this time the inventor became able to perform over 20 upper body exercises that were previously not possible or painful to perform with any significant amounts of weight.

From a strength training perspective, the Carter Cuff allows for the ability to train the upper body in a more balanced, functional manner. The biggest benefit of the Carter Cuff is its ability to allow (or sometimes better allow) for loaded scapular retraction and depression, shoulder adduction, abduction, flexion and extension, and elbow flexion and extension. In “gym lingo”, the user can row, press, pull down, press down, curl, chop and perform suspension, barbell, dumbbell and kettle bell work, all while loading the body evenly. 

Prior to the invention of the Carter Cuff there was a drastic imbalance between the inventor’s shoulders, chest, back and lateral trunk. With supervision and direction by a team of elite-level fitness coaches, these imbalances were eradicated through targeting the deltoids (rear in particular), rhomboids, lattimus dorsi, trapezius, triceps and biceps in both an isolated and synergistic fashion. The Carter Cuff has transformed the inventor’s upper body into one that is symmetrical and muscular and has allowed the inventor to create a stronger and more stable girdle and trunk, and consequently, entire body.

In addition, there is an important aesthetic aspect to the Carter Cuff. Many orthotic, prosthetic or rehabilitation devices, while utilitarian, are aesthetically lacking. The Carter Cuff also serves important and often overlooked stylistic and aesthetic purposes: in other words, it looks great and stands out in a positive way. This remains an especially important consideration for amputees dealing with the sudden change in the body and the resulting body image issues.

The Carter Cuff is currently in use at Walter Reed National Military Medical Center in Bethesda, Maryland, and clinical tests are being conducted in conjunction with San Francisco State University's Department of Kinesiology. 
United States and international patents have been secured.
