The present patent specification relates to the field of therapeutic devices for the hands. More specifically, this patent specification relates to gloves for arresting involuntary clenching of the hands to straighten the fingers and improve hand function.
Often, as a result of aging, injury, or degenerative diseases such as arthritis, the hands of an individual may involuntarily clench as the fingers contract towards the palm. This involuntary clenching may also be due to inflammation, overuse or repetitive hand motions, swollen joints, damaged tissue or cartilage and other strain induced activities that weaken the muscles and ligaments in the hand. This clenching often occurs more at night while the individual is sleeping and is unable to prevent the clenching. Over time, repeated involuntary hand clenching may result in a reduced range of motion and weakness in the fingers and joints causing the hands to develop a claw like appearance.
Unfortunately, this debilitating and painful condition of involuntary hand clenching usually causes the individual exhibiting such behavior a great deal of distress or embarrassment. These individuals may find it difficult to unclench the hand upon waking This involuntary nocturnal clenching may even interfere with the ability of the individual to enter or maintain sleep. Furthermore, involuntary hand clenching may lead to additional hand and wrist weakness, the inability to hold on to objects, and even the lack of ability to pick up smaller objects. This involuntary clenching of the hands contributes significantly to the number of individuals who eventually become disabled due to the inability to use or work with their hands. According to the Center for Disease Control, more than 27 million Americans—more than 10% of the U.S. population—have been diagnosed with some form of arthritis and is the most common cause of disability among adults.
Currently, treatment for pain and swelling in the hands is limited to the use of compression gloves or varying types of finger splints. These gloves are made of an elastic material that compresses the hand of a user in an effort to limit the swelling that occurs from inflammation and to promote better blood circulation. Since these compression gloves provide a uniform compression over the surface of the hands and fingers, they are not capable of adequately decreasing the degree to which the hand is able to clench. As a result, these compression gloves are only able to slow the progression of the involuntary clench to a nominal degree, if at all.
Therefore, a need exists for novel therapeutic devices that are able to arrest involuntary clenching of the hands. There is a further need for a novel therapeutic device that can be worn on the hands for long periods of time, such as through the sleep cycle. A further need exists for novel therapeutic devices that are able to train the hand and reverse the effects of involuntary hand clenching. Finally, there exists a need for novel therapeutic devices that are adjustable and able to provide a varying degree of resistance to each individual finger to prevent or reverse the effects of involuntary clenching of the hands.
A glove configured to be worn on the hand of a user to prevent involuntary clenching of the hand is disclosed herein. In some embodiments, the glove may comprise: a dorsal region adapted to cover the back of a person's hand, with the dorsal region comprising a pull strap anchor positioned on the exterior surface of the glove; a thumb phalange region which may be coupled to a first end of a first pull strap and which may extend outwardly from the dorsal region; an index phalange region which may be coupled to a first end of a second pull strap and which may extend outwardly from the dorsal region; a middle phalange region which may be coupled to a first end of a third pull strap and which may extend outwardly from the dorsal region; a ring phalange region which may be coupled to a first end of a fourth pull strap and which may extend outwardly from the dorsal region; and a little phalange region which may be coupled to a first end of a fifth pull strap and which may extend outwardly from the dorsal region. The first, second, third, fourth, and fifth pull straps may each further comprise a second end removably coupled to the pull strap anchor thereby exerting a reverse counterforce against the phalange regions as to open the hand and prevent involuntary clenching.
In further embodiments, the dorsal region, thumb phalange region, index phalange region, middle phalange region, ring phalange region, and little phalange region may be constructed from a compressionable material.

Tension may be applied to a pull strap 21, 22, 23, 24, and 25 by pulling a second end 21B, 22B, 23B, 24B, and 25B until the desired amount of reverse counterforce against the phalange regions as to resist the moving of a phalange region 14, 15, 16, 17, and 18, toward the anterior region 12 (
While some preferred materials for elements have been described, the glove 100 is not limited by these materials. In other embodiments, one or more elements that comprise the glove 100 may be made from durable materials such as hard plastics, metal alloys, wood, hard rubbers, carbon fiber, fiber glass, resins, polymers or any other suitable materials including combinations of materials. Additionally, one or more elements may be made from or comprise durable and slightly flexible materials such as soft plastics, silicone, soft rubbers, fabrics, or any other suitable materials including combinations of materials.
