Noninvasive Approach Relieves Carpal Tunnel Syndrome

A new wrist brace system provides an effective, noninvasive treatment for carpal tunnel syndrome (CTS).

The aPallo Wrist brace system consists of two braces: a brace for rest—the aPallo night brace and a brace for action— the aPallo day brace. For nighttime use, the polyurethane-leather brace provides cool comfort, while keeping the wrist perfectly neutral by employing anatomical features to keep the four fingers in an extended position at the metacarpophalangeal joints, while leaving the index finger free. In addition, by holding the fingers in the straightened position, the brace improves relaxation of the carpal tunnel. This position keeps the lumbricalmuscles from pressing on the median nerve, which causes the symptoms of CTS.


The day brace employs a palm-free design that still manages to maintain the wrist in the ideal neutral position by using a dorsal metal spar support. In addition, the integrated cinch strap allows rapid adjustment for wrist movement as needed, without removing the brace. An included ice pack provides optional cold therapy directly over the carpal tunnel. The day brace is made of a breathable fabric with a protective lycra sleeve to prevent Velcro catching and improve cosmesis. The aPallo Wrist brace system is a product of Palo Medical (Covington, LA, USA).

CTS is a median entrapment neuropathy that causes paresthesia, pain, numbness, and other symptoms in the distribution of the median nerve. It appears to be caused by a combination of genetic and environmental factors, including diabetes, pregnancy, obesity, hypothyroidism, and heavy manual work or work with vibrating tools. Other disorders such as bursitis and tendinitis have been associated with repeated motions performed in the course of normal work or other activities.

The aPallo Wrist brace system was developed by orthopedic surgeon Matti Palo, MD, who previously suffered from CTS.
