Multi-Functional Apparatus, Kit, and Method for Dexterity Enhancement

This application claims the benefit of U.S. Provisional Application No. 63/646,252, filed on May 13, 2024. The entire disclosure of the above application is incorporated herein by reference.

The present technology relates to a therapeutic device for motor skill rehabilitation and, more particularly, to an apparatus designed to facilitate the training and enhancement of various hand grasp patterns and upper extremity strength.

This section provides background information related to the present disclosure which is not necessarily prior art.

Therapeutic devices for motor skill rehabilitation may be used for patients recovering from injury, surgery, or suffering from a condition that impairs fine motor skills and dexterity. A variety of tools may be employed to address different aspects of hand functionality, such as strength, coordination, and grasp patterns. However, the use of multiple tools may be cumbersome, expensive, and may not provide a comprehensive solution to address the necessary motor skills.

One issue with certain therapeutic devices may be the limited scope in addressing various grasp patterns. Grasp patterns may be essential for performing daily tasks and require specific training to improve. Certain tools often focus on a single grasp pattern or a limited set of grasp patterns, which may not be sufficient for a holistic rehabilitation process. This limitation may necessitate the use of multiple devices, each targeting a different grasp pattern, leading to increased complexity and cost for both therapists and patients.

Another issue with certain therapeutic devices may be the lack of integration between strength training and fine motor coordination. Devices that focus on building strength may not adequately address the precision required for fine motor tasks, while tools designed for dexterity may not offer the resistance needed to improve muscle strength. This disconnect may result in an incomplete rehabilitation process, where patients may gain strength but not the dexterity required for everyday activities.

Accordingly, there is a continuing need for an integrated solution that may address a full spectrum of hand functionality required for effective motor skill rehabilitation. Desirably, such a solution may offer a single, versatile device capable of facilitating multiple grasp patterns and combining strength training with fine motor coordination. This may not only streamline the therapeutic process but also enhance an engagement of a patient and a potential for recovery.

In concordance with the instant disclosure, an integrated solution that addresses the full spectrum of hand functionality required for effective motor skill rehabilitation in a single, versatile device capable of facilitating multiple grasp patterns and combining strength training with fine motor coordination, and which streamlines the therapeutic process and also enhances the patient's engagement and potential for recovery, has surprisingly been discovered.

The present technology includes articles of manufacture, systems, and processes that relate to the enhancement of hand dexterity and strength through a versatile, multi-functional training device designed to accommodate a variety of grasp patterns and adjustable resistance features for comprehensive upper extremity rehabilitation.

In certain embodiments, a therapeutic apparatus may be designed to facilitate rehabilitation of a user by incorporating a housing having a graspable exterior surface. A handle, a knob, and a slot may be formed on the housing. The handle may include a plurality of surfaces configured to enable a hook grasp and a cylindrical grasp by the user. The knob may be formed on the housing having a surface with an interchangeable shape configured to enable at least one of a pincer grasp through thumb and index finger opposition, a tip grasp through finger and thumb tip control, a jaw chuck grasp through thumb opposing multiple fingers, and a spherical grasp through conforming fingers and thumb around a spherical surface. The slot may be configured to facilitate a lumbrical grasp and a lateral grasp by the user. A weight may be removably attached to or disposed within the housing for adjusting a weight of the therapeutic apparatus.

In certain embodiments, a method for rehabilitating a user utilizing the therapeutic apparatus is disclosed. The method involves providing the user with the therapeutic apparatus and a selection of removable weights. For example, a therapeutic apparatus having a housing, a handle, a knob, and a slot formed on the housing and a plurality of removable weights.

In certain embodiments, a kit for rehabilitation is provided, which includes the therapeutic apparatus with its multi-functional main body designed for facilitating various grasp patterns. The therapeutic apparatus may include housing having a handle, a knob, and a slot formed on the housing. A scannable code may be configured to connect to a mobile application for providing instructions for using the kit. The kit may also contain a plurality of removable weights, each capable of being magnetically attached to the therapeutic apparatus. These weights may be designed for incremental adjustment of the apparatus's weight, enabling users to customize the resistance level according to their rehabilitation progress. The kit may further include an instructional material to guide the user through various exercises. The kit may enable a user to improve hand function and strength in a systematic manner.

Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

The following description of technology is merely exemplary in nature of the subject matter, manufacture, and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed, unless expressly stated otherwise. “A” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. “About” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.

Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding. additional materials, components, or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.

As referred to herein, disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping, or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.

When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer, or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The present technology may improve adaptability and effectiveness of a rehabilitation exercise by integrating a range of grasp types and weight adjustments into a single apparatus. This approach may reflect the specific needs of a user at various stages of recovery and also facilitate a more engaging and motivating experience. By consolidating multiple therapeutic functions into one device, the present technology may reduce the clutter of equipment, streamline the therapy process, and accelerate progress of the user through consistent and targeted practice. Furthermore, a magnetic attachment of weights may enhance the convenience and ability to adjust resistance levels and further contribute to a rehabilitation routine.
