The fabric includes a weave of fibers, where the fibers include an elastic fiber covered by a covering material. The fabric also includes a first end and a second end, where the second end is opposite the first end. The fabric further includes one or more rounded corners. The pre-cut strip of kinesiology tape also includes a longitudinal cut in the fabric. The longitudinal cut passes through at least a portion of the fabric and extends from the first end to a pre-determined distance from the second end. The pre-cut strip of kinesiology tape also includes adhesive on a first surface of the fabric, where the adhesive is configured to adhere the fabric to a human body.
The following summary is intended to introduce the reader to various aspects of the specification, but not to define or delimit any invention.
According to some aspects, a precut kinesiology tape for wrist support is disclosed. The precut kinesiology tape comprises a strip of woven material having a first face and an opposed second face, a length and a width, wherein the width is shorter than the length, and a length stretch ratio along the length and a width stretch ratio along the width. The width stretch ratio is greater than the length stretch ratio. An adhesive is on the first face in a discontinuous pattern.
The strip may have a high width stretch ratio, and a low length stretch ratio. The strip may be at least twice as stretchable in a widthwise direction than in a lengthwise direction. The width stretch ratio may be at least 1.4, or at least 1.6. The length stretch ratio may be at most 1.3, or at most 1.2.
The length may be between about 130 mm and 270 mm, and the width may be between about 45 mm and 100 mm. The length may be between about 160 mm and about 240 mm, and the width may be between about 55 mm and about 90 mm. The length may be at least about 2 times the width, or at least about 2.5 times the width, or at least about 2.75 times the width.
The material may comprise woven cotton.
The tape may extend lengthwise between a first end and a second end. The first end may comprise a first alignment feature, and the second end may comprise a second alignment feature for aligning with the first alignment feature.
The adhesive may be provided in bands, and the bands may extend generally widthwise across the tape. The bands may be provided in a wave pattern.
According to some aspects, a method of supporting a wrist is disclosed. The method comprises a) positioning a piece of kinesiology tape adjacent the wrist so that a greater stretch axis of the tape is generally aligned along the wrist and a lesser stretch axis of the tape extends generally transverse to the wrist; b) wrapping the piece of kinesiology tape at least partially around the wrist, wherein during step b) the kinesiology tape is at most stretched minimally along the low stretch axis; and c) adhering the piece of kinesiology tape to the wrist.
The kinesiology tape may have an unstretched length, and during step b), the kinesiology tape may be stretched to a stretched length that is at most 1.3 times the unstretched length, or at most 1.2 times the unstretched length.
The piece of kinesiology tape may have an unstretched width, and may be stretchable to a stretched width that is at least 1.4 times the unstretched width. During step b), the piece of kinesiology tape may be stretched at most minimally along the high stretch axis.
A release liner may be provided on the piece of kinesiology tape. The method may further comprise, prior to step a), removing a central portion of the release liner from the piece of kinesiology tape.
Steps b) and c) may comprise: i) adhering a central portion of the piece of kinesiology tape to the wrist; ii) removing end portions of the release liner from the end portions of the piece of kinesiology tape; iii) wrapping the end portions of the piece of kinesiology tape at least partially around the wrist; and iv) adhering the end portions of the piece of kinesiology tape to the wrist.
According to some aspects, a kit for wrist support is disclosed. The kit comprises a precut kinesiology tape. The tape comprises a strip of woven material having a first face and an opposed second face, a length and a width, wherein the width is shorter than the length, and a length stretch ratio along the length and a width stretch ratio along the width. The width stretch ratio is greater than the length stretch ratio. An adhesive is on the first face in a discontinuous pattern. The kit further comprises a release liner on the first face. The release liner comprises a first line of weakness and a second line of weakness spaced apart from the first line of weakness in a lengthwise direction. The first line of weakness and the second line of weakness extend a widthwise direction.
The drawings included herewith are for illustrating various examples of articles, methods, and apparatuses of the present specification and are not intended to limit the scope of what is taught in any way. In the drawings:
Various apparatuses or processes will be described below to provide an example of an embodiment of the claimed subject matter. No embodiment described below limits any claim and any claim may cover processes or apparatuses that differ from those described below. The claims are not limited to apparatuses or processes having all of the features of any one apparatus or process described below or to features common to multiple or all of the apparatuses described below. It is possible that an apparatus or process described below is not an embodiment of any exclusive right granted by issuance of this patent application. Any subject matter described below and for which an exclusive right is not granted by issuance of this patent application may be the subject matter of another protective instrument, for example, a continuing patent application, and the applicants, inventors or owners do not intend to abandon, disclaim or dedicate to the public any such subject matter by its disclosure in this document.
Disclosed herein is a precut kinesiology tape, and related kits and methods, which may be used for wrist support. For example, the precut kinesiology tape may be used to treat, prevent, or inhibit wrist pain, or to treat, prevent, or inhibit wrist injuries. Such wrist pain and injuries may be associated with, for example, carpal tunnel syndrome, sprains, tendonitis, arthritis, and/or gout.
In some examples, the precut kinesiology tape may be wrapped at least partially around a wrist, to support the wrist. As will be described in further detail below, the precut kinesiology tape may configured such that it is highly stretchable along its width, but minimally stretchable or non-stretchable along its length. In use, when wrapped around a wrist, the width of the tape may extend along and be generally aligned with the wrist (i.e. generally parallel to the forearm), and the length of the tape may be generally transverse to the wrist (i.e. generally perpendicular to the forearm). Because the tape is minimally stretchable or non-stretchable along the length, in use, over-compression of the wrist may be avoided, inhibited, or prevented. Furthermore, because the tape is highly stretchable along its width, in use, interference with wrist movement may be avoided, inhibited, or prevented, and comfort may be enhanced.

Referring to
The strip 102 has a stretch ratio along its length 104 (also referred to as a length stretch ratio), and a stretch ratio along its width 106 (also referred to as a width stretch ratio). As used herein, the term ‘stretch ratio’ refers to a dimension of the strip 102 when stretched elastically to its maximum extent, divided by a dimension of the strip 102 when unstretched. For example, referring to
In the example shown, the width stretch ratio is greater than the length stretch ratio. For example, the strip 102 may be at least twice as stretchable in a widthwise direction than in a lengthwise direction. For further example, the width stretch ratio may be at least 1.4 or about 1.4, and the length stretch ratio may be at most 1.3 or about 1.3. For further example, the width stretch ratio may be at least 1.6 or about 1.6, and the length stretch ratio may be at most 1.2 or about 1.2. For further example, the length stretch ratio may be between 1.4 and 2.0, and the width stretch ratio may be between 1.0 and 1.3.
In this document, a stretch ratio of 1.4 or greater may be referred to as a ‘high’ stretch ratio, and a stretch ratio of 1.3 or less (including a stretch ratio of 1) may be referred to as a ‘low’ stretch ratio. A material with a stretch ratio of 1 may also be referred to as ‘non-stretchable’. Furthermore, the transverse axis 108, along which the strip 102 has a greater stretch ratio, may be referred to as a ‘greater stretch axis’. The longitudinal axis 110, along which the strip 102 has a lower stretch ratio, may be referred to as a ‘lesser stretch axis’.
Referring back to
An adhesive 116 is on the first face 112. Referring still to

In some examples, as shown in
The alignment features 140 and 142 may facilitate the wrapping of the tape 100 in a straight fashion, and the tape 100 may be wrapped so that the protrusion of the first alignment feature 140 is received in or pointing towards the indentation of the second alignment feature 142.
To adhere the tape 100 to the wrist 900, the tape may be pressed against the wrist 900, and optionally rubbed.
Because the strip 102 has a low stretch ratio along the longitudinal axis 110, the strip 102 may remain minimally stretched or non-stretched (i.e. at most minimally stretched) as it is wrapped around the wrist 900. For example, the strip 102 may be stretched to a stretched length that is at most 1.3 times its unstretched length, or at most 1.2 times its unstretched length. This may avoid, inhibit, or prevent over-compression of the wrist 900 by the tape 100. This in turn may enhance comfort.
Furthermore, even though the strip 102 has a high stretch ratio along the transverse axis 108, it may be applied in a non-stretched or minimally stretched configuration along the transverse axis 108.
Because the strip 102 has a high stretch ratio along the transverse axis 108, the tape 100 may support the wrist 900 while avoiding, inhibiting, or preventing interference with wrist movement. For example, the tape 100 may support the wrist 900 while still allowing for flexion and extension of the wrist 900, and radial and ulnar deviation of the wrist 900. Furthermore, comfort may be enhanced.
