Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a continuation of International Patent Application No. PCT/KR2020/013546, filed on Oct. 6, 2020, which is based upon and claims the benefit of priority to Korean Patent Application Nos. 10-2019-0124147 filed on Oct. 7, 2019 and 10-2020-0051231 filed on Apr. 28, 2020. The disclosures of the above-listed applications are hereby incorporated by reference herein in their entirety. 
    
    
     BACKGROUND 
     Embodiments of the inventive concept relate to a rehabilitation glove. 
     A spasticity phenomenon is a phenomenon, in which an entire body of a person is paralyzed mainly due to cerebral strokes or stroke diseases, and refers to a phenomenon, in which a hand, an arm, a leg, and the like of a user is stiffened while being curved. In particular, a user having a spasticity phenomenon in a hand and a finger may be accompanied with pain when he or she closes a hand for a long time, and his or her health may deteriorate due to a nerve problem such as musculoskeletal system disorders. 
     Accordingly, a user having spasticity in a hand has to perform rehabilitation training for relaxing a finger having spasticity by spreading the finger periodically to reduce pain and prevent diseases from being worsened. 
     The rehabilitation training is performed by using a rehabilitation glove, and the rehabilitation glove is a glove for users who requires a rehabilitation treatment for alleviating a spasticity phenomenon in a hand and a finger. 
     The rehabilitation glove may support rehabilitation training of a hand and a finger for minimizing a contracture phenomenon of a finger having spasticity and securing lengths of muscles by extending detachable spasticity alleviating straps formed on upper sides of fingers in a direction, in which the fingers of the user are spread. 
     However, a rehabilitation glove product utilized conventionally is configured such that joints of fingers are spread at once by using one strap in one finger. Accordingly, it is difficult for a user to sufficiently achieve an effect of training because it is difficult to finely adjust a degree of grasping a hand by himself or herself during a rehabilitation exercise. Furthermore, it may cause an inconvenience in carrying out everyday activities at a time point, at which the spasticity of the user is lowered. 
     Furthermore, in the conventional rehabilitation glove product, a spasticity alleviating strap is located at an end bone part of a finger, and thus a function of spreading a finger is not minimized so that an end of the hand cannot be properly spread, whereby an efficiency of rehabilitation training for alleviating a spasticity phenomenon of the user is low. 
     SUMMARY 
     Embodiments of the inventive concept provide a rehabilitation glove that may assist motion of a finger.

     Hereinafter, exemplary embodiments of the inventive concept will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the inventive concept pertains may easily carry out the inventive concept. However, the inventive concept may be implemented in various different forms, and is not limited to the embodiments. Further, to clearly describe the inventive concept, parts that are irrelevant to the description are excluded from the drawings and the similar parts are denoted by similar reference numerals throughout the specification. 
     Throughout the specification, when it is described that a part is “connected” to another part, it means not only that they are ‘directly connected’ to each other but also that they ‘are electrically connected to each other while another element is interposed therebetween’. Furthermore, it should be understood that when a part includes an element, it means that another element is not excluded but may be further included unless particularly described in an opposite way, and presence or additional possibility of one or more other features, numbers, steps, operations, elements, and partial products, or combinations thereof is not excluded in advance. 
     Hereinafter, various embodiments of the inventive concept will be described with reference to the accompanying drawings. 
     A rehabilitation glove according to various embodiments of the inventive concept is directed to alleviating pain of a user having spasticity in hands and fingers and preventing a phenomenon, in which muscles and nerve diseases deteriorate, and is configured to minimize a contracture phenomenon of hands and fingers of a user having spasticity and allow rehabilitation training of an entire palm of a hand or an entire bottom of a finger. 
     First Embodiment 
     Hereinafter, a rehabilitation glove according to a first embodiment of the inventive concept will be described. 
       FIG. 1  is a view illustrating the rehabilitation glove according to the first embodiment of the inventive concept.  FIG. 2  is a side view of the rehabilitation glove according to the first embodiment of the inventive concept. 
     Referring to  FIGS. 1 and 2 , a rehabilitation glove  100  according to the first embodiment of the inventive concept includes a body  110  formed to cover a hand of a user (a wearer) such that the user puts on the rehabilitation glove  100 , and a strap unit  120  coupled to the body  110 , and formed to provide a tensile force in a direction, in which a knuckle of the user is spread at a hand back portion of the user. 
     The strap unit  120  formed on an upper side of the finger or the hand back portion located in the body  110 , as illustrated in  FIGS. 1 and 2 , includes a first strap  121  and a second strap  122  connected side by side along a direction, in which one finger of the user extends to deliver a tensile force for spreading a knuckle. Furthermore, the strap unit  120  may further include a third strap  123  disposed side by side with the first strap  121  and the second strap  122 . Here, the extension direction of the finger may be any one of opposite directions, in which a portion of the body that accommodates the finger of the user extend, and in the present embodiment, may refer to a direction (a direction that faces a left side from a right side of  FIG. 3 , which will be described below) that faces the hand back from an end of the finger. 
     In more detail, in the rehabilitation glove  100 , a plurality of strap units  120  may be formed in one finger, that is, the first strap  121 , the second strap  122 , and the third strap  123  may be disposed at finger bone parts and a hand back portion. 
     According to the embodiment of the inventive concept, the first strap  121  may be disposed in a distal bone part of the finger, the second strap  122  may be disposed in a bone part that is next to the bone part, in which the first strap  121  is disposed, and the third strap  123  may be disposed over a hand back portion in a bone part that is next to the bone part, in which the second strap  122  is disposed. Accordingly, because the user may pull the first strap  121 , the second strap  122 , and the third strap  123  connected according to the bone part portions of the finger by applying a force to them, the user may adjust strengths applied to the bone parts differently according to spasticity levels. In addition, the user may pull and spread the finger having spasticity by applying forces that are lower than when one entire strap is pulled at once, to the first to third straps  121  to  123  one by one. 
       FIG. 2  is an illustration of an embodiment, in which the strap unit  120  is disposed at a thumb portion of the user, and as in  FIGS. 1 and 2 , the strap unit  120  may be designed such that two or three straps are disposed in one finger according to a length of a finger and lengths of the straps. 
       FIG. 3  is a side view of a strap unit of the rehabilitation glove according to the first embodiment of the inventive concept. 
     In a more detailed description of the first strap  121  according to the embodiment of the inventive concept through  FIG. 3 , one end of the first strap  121  is coupled to a portion of the body  110 , which surrounds an end of the finger of the user, and an opposite end of the first strap  121  is disposed at a location, at which it contacts one end, at which the second strap  122  starts, to be coupled to be detachably attached to the second strap  122 . An opposite end of the second strap  122  may be coupled to be detachably attached to a portion of one end of the third strap  123  or the body  110 , which covers a hand back or a wrist of the user. 
     According to the embodiment of the inventive concept, the opposite end of the first strap  121  and the one end of the second strap  122  may be attached to each other to overlap each other. 
     In more detail, the one end of the first strap  121  may be located at an end of the finger in the body  110  to be fixedly connected to the body  110 , and a Velcro fastener may be formed at the opposite end of the first strap  121  to be detachably attached to an upper surface of the second strap  122 . Similarly, the one end of the second strap  122  also may be fixedly connected to the body  110 , and a Velcro fastener may be formed at the opposite end of the second strap  122  such that the opposite end of the second strap  122  may be detachably attached to the third strap  123  or the body  110 . When the third strap  123  is further included, the one end of the third strap  123  may be coupled to the body  110 , and the opposite end of the third strap  123 , at which a Velcro fastener is formed, may be detachably attached to the body  110 . According to the configuration, the strap unit  120  may be configured such that the straps are connected to each other side by side without any broken portion to deliver a force such that all the parts ranging from the finger bone parts to the palm are relaxed. Meanwhile, a portion of a surface or an entire surface of the body  110  may be formed of a material, to which the Velcro fasteners of the first to third straps  121 ,  122 , and  123  may be detachably attached. 
     As described above, because ends of the first strap  121  and the second strap  122  are disposed side by side to overlap each other, the user may sequentially detach the opposite end of the first strap  121  from the body  110  or the second strap  122 , extend the first strap  121  such that the first bone part of the finger is spread, attach the first strap  121  to the second strap  122 , detach the second strap  122  from the body  110  or the third strap  123 , extend the second strap  122  such that the next bone part of the finger is spread, and attach the second strap  122  to the body  110 . Similarly, the third strap  123  may be detached from the body  110 , and the third strap  123  may extend such that the entire finger and the entire palm are spread and may be attached to the body  110  again. 
     In this way, because the first strap  121 , the second strap  122 , and the third strap  123  are sequentially detached and are attached again such that the bone parts of the finger, the finger, and the wrist are spread, magnitudes of tensile forces of the first strap  121 , the second strap  122 , and the third strap  123  disposed at the corresponding locations may be adjusted according to spasticity levels and degrees for the finger bone parts. Accordingly, the rehabilitation glove  100  according to the inventive concept may optimize a function of spreading the finger of the user having spasticity as a whole, according to situations. 
     In detail, the user may carry out rehabilitation training of the bone parts of a finger, as well as the finger of the desired portion, through the strap unit  120  including the plurality of straps. For example, the portions of the bone parts of the finger having spasticity may be relaxed and alleviated by pulling the first strap  121  and the second strap  122 , and the portions of the fingers and the palm having the spasticity may be relaxed and alleviated by utilizing the third strap  123 . 
     Meanwhile, the one end of the first strap  121  is directly connected to the body  110 , but the ends of the second strap  122  and the third strap  123 , as illustrated in  FIG. 3 , may be connected to the body  110  through support rings  122   a  and  123   a . The support rings  122   a  and  123   a  have ring shapes that surround the finger, such that the ends of the second strap  122  and the third strap  123  are attached to outsides thereof and inner sides thereof are attached to the body  110 . Detailed shapes and functions of the support rings  122   a  and  123   a  will be described further with reference to  FIG. 4 . 
       FIG. 4  is a view of the support ring of the strap unit of the rehabilitation glove according to the first embodiment of the inventive concept. 
     Referring to  FIGS. 3 and 4 , the second strap  122  may include the support ring  122   a  supported by the body  110  such that the finger of the user is surrounded at the one end thereof coupled to the first strap  121 . The third strap  123  also may include the support ring  123   a  supported by the body  110  such that the finger of the user is surrounded at the one end thereof coupled to the second strap  122 . 
     The support ring  122   a  according to the embodiment of the inventive concept, as illustrated in  FIG. 1 , may have a first ring part  122   a   1  formed to surround a portion of a circumference of the finger of the user, and a second ring part  122   a   2  formed to surround the remaining portions of the circumference of the finger of the user and coupled to the first ring part  122   a   1  to cross the first ring part  122   a   1  at a preset angle. 
     The support ring  123   a  coupled to the one end of the third strap  123  also may include a first ring part (not illustrated) formed to surround a portion of a circumference of the finger of the user, and a second ring part (not illustrated) coupled to the first ring part (not illustrated) to cross the first ring part (not illustrated) at a preset angle. 
     With the configuration, the support rings  122   a  and  123   a , as illustrated in  FIG. 3 , may be disposed in an inclined form, in which they are inclined with respect to the extension direction of the finger when viewed from a side. With the configuration, even when the user pulls the second strap  122  and the third strap  123  along a surface of the body  110  (along a horizontal direction of  FIG. 3 ) to relax the hand and the finger, the first ring part  122   a   1  and the second ring part  122   a   2  may effectively endure a tensile force while a state, in which they are adhered to the body  110 , is maintained. 
     Second Embodiment 
     Hereinafter, a rehabilitation glove according to a second embodiment of the inventive concept will be described. 
       FIG. 5  is a view illustrating an entire appearance of the rehabilitation glove according to the second embodiment of the inventive concept. 
     A rehabilitation glove  200  according to the second embodiment of the inventive concept includes a body  210  formed to cover a hand of the user to be mounted on the hand, and a strap unit  220  coupled to the body  210  and formed to provide a tensile force in a direction, in which a joint of the finger of the user is spread at the hand back portion of the user. 
     In detail, the strap unit  220  may include a finger strap  221  formed to deliver a tensile force along a direction, in which one finger of the user extends, and a hand back strap  226 , in which an end of the finger strap  221  is coupled to one side surface thereof and an opposite surface of which is coupled to a surface of the body  210  such that a tensile force of the finger strap  221  is delivered to the body  210 . 
     Furthermore, the body  210  according to another embodiment of the inventive concept may include a thimble part  211  formed to surround an end of a finger of the user and coupled to one end of the finger strap  221 . One end of the finger strap  221  may be fixedly connected to the body  110 , and an opposite end thereof may include a Velcro fastener to be detachably attached to the body  110  or the hand back strap  226  by the thimble part  211 . In more detail, an opposite end of the finger strap  221  may be detachably attached to the hand back strap  226  to overlap the hand back strap  226 . Accordingly, the finger strap  221  and the hand back strap  226  may be connected to each other to relax the fingers and the palm as a whole. 
     The one end of the finger strap  221 , as illustrated in  FIG. 5 , is located at a portion of the body  110  corresponding to an end of the hand to perform rehabilitation training of completely spreading the hand of the user. Accordingly, the user may completely relax and spread all portions of the fingers and the palm having spasticity by utilizing the rehabilitation glove  100 . 
     Moreover, the user may relax and alleviate portions of the fingers having spasticity by pulling the finger strap  221 , and may relax and alleviate portions of all the fingers and the palm having spasticity by utilizing the hand back strap  226 . 
     Furthermore, according to another embodiment of the inventive concept, the body  210  may further include a guide part  212  formed at a portion of a finger. The plurality of guide parts  212  may be disposed to be spaced apart from each other along the extension direction of the finger of the user, and the finger strap  221  may be interposed between the guide part  212  and the body  210 . 
     In more detail, the guide part  212  may be disposed at the bone part of the finger, and may uniformly deliver a force of spreading the entire finger as the force is delivered to the bone part of the finger by the guide part  212  when the finger strap  221  is pulled. For example, as illustrated in  FIG. 5 , two guide parts  212  may be disposed in each bone part of the finger, and may be disposed between the first and second bone parts and may be disposed between the second and third bone parts. Furthermore, the plurality of guide parts  212  may fix and support the finger strap  221  such that the finger strap  221  does not deviates to a side of the finger when the user closes the hand. 
       FIGS. 6A, 6B, and 6C  are views illustrating an embodiment of a hand back strap of a strap unit of the rehabilitation glove according to the second embodiment of the inventive concept. 
     According to the hand back strap  226 , rehabilitation training of spreading the finger and the hand back at once by pulling the plurality of finger straps  221  at once may be performed by detachably attaching the hand back strap  226  to the body  110 . 
       FIG. 6A  illustrates a state, in which the finger straps  221  are attached to the hand back strap  226  while the user closes the hand. The user may detach the hand back strap  226  from the body as illustrated in  FIG. 6B , and may pull the hand back strap  226  to the hand back portion of the body toward the body of the user and attach the hand back strap  226  as illustrated in  FIG. 6C  to carry out rehabilitation training of relaxing the all portions of the fingers and the palm at once or relaxing the wrist toward the hand back. 
       FIG. 7  is a graph depicting an experimental result of elasticity of the strap units in the first embodiment and the second embodiment of the inventive concept. 
     Hereinafter, designs of the materials of the first to third straps  121  to  123  and the finger strap  221  according to the inventive concept will be described. 
     First, ranges of forces that are necessary for spreading fingers for rehabilitation exercises may be classified according to symptom levels of users, and may be generally classified into six stages according to Brunnstrom recovery stages (BRSs). 
     In more detail, stage 1 is a flaccid paralysis stage, in which voluntary movement of all legs is impossible, and stage 2 is a stage, in which associated movement or comitance of a basic leg appears as spasticity is gradually developed so that slight autokinesis is possible. Stage 3 is a stage, in which spasticity is strongest, and the user may voluntarily perform comitance. In stage 4, several voluntary movements separated from comitance may be possible as spasticity of the user gradually decreases, in stage 5, more difficult movements may be performed as comitance of arms and legs of the user is lost, and in stage 6, spasticity of the user disappears and individual joint movements are restored to appear normal. 
     Meanwhile, a user corresponding to stage 1 may require a force of 0 kgf to 1.5 kgf to spread a finger, a user corresponding to stages 2 and 4 may require a force of 0.5 kgf to 3 kgf, and a user corresponding to stage 3 may require a force of 2 kgf to 3.5 kgf. Stages 5 and 6 are stages, in which stiffening of the user disappears, and thus a force of a specific range may not be required. 
     Based on this, a material, by which a tensile force may be shown at a length of the same level as those of the fingers, may be applied. Because a range of maximum values, by which grasping power may be show, is 0 kgf to 3.5 kgf, to apply a material having an elastic coefficient that is suitable for a spasticity degree of most of nerve damaged users, referring to  FIG. 7 , a range of elastic coefficients of the first strap  121  and the second strap  122  may be set to 167 N/m 2  to 289 N/m 2  (0.76 MPa to 0.86 MPa). 
     A result of  FIG. 7  is a measurement result obtained by pulling the straps  121 ,  122 ,  123 , and  221  of the rehabilitation gloves  100  and  200  according to the inventive concept to a maximally prolonged length by using a tensile tester (for example, a push-pull gauge). Forces N (kgf) at maximum lengths may be identified on a transverse axis, and prolonged lengths (mm) of the straps may be identified on a longitudinal axis. 
     A material elasticity test was performed while forces N (kgs) are increased until the straps were deformed, in which lengths of the straps for the fingers are 97 mm for a thumb, 136 mm for an index finger, 142 mm for a middle finger, 132 mm for a ring finger, and 109 mm for a little finger, before the test, and lengths of the straps for the fingers are 103 mm for a thumb, 140 mm for an index finger, 149 mm for a middle finger, 139 mm for a ring finger, and 113 mm for a little finger, after the test. As a whole, the lengths are increased by 4 mm to 7 mm, and are restored by 3 mm to 4 mm after the straps are left as they are for about two days after the test. 
     As may be identified in a graph of  FIG. 7 , a maximum length may be maintained when a pulling force is 2 kgf to 4 kgf, and also a prolonged length is the same as a maximally prolonged length even when the pulling force is up to 15 kgf. 
     Accordingly, finger rehabilitation training may be performed by setting elastic coefficients of the straps  121 ,  122 ,  123 , and  221  to 167 N/m 2  to 289 N/m 2  and repeating an act of spreading the finger by pulling the first to third straps  121  to  123 , and the finger strap  221  and bending and spreading the finger by the user. 
     Furthermore, the strap units  120  and  220  may be formed of a flexible material, and may be formed of materials such as silicon, span, neoprene, and rubber. Rehabilitation training intensity may be secured by an elastic force provided by the flexible straps. 
     According to the rehabilitation gloves  100  and  200 , the strap units  120  and  220  include the first strap  121 , the second strap  122 , the third strap  123 , the finger strap  221 , and the hand back strap  226 , whereby rehabilitation training is helped to be performed with no difficulty as the user wears the rehabilitation glove  100  in everyday lives. Moreover, general exercises and rehabilitation training may be performed together as the wearer wears the rehabilitation glove  100  in cycling, outdoor activities, and other exercises using sport outfits. 
     In particular, the rehabilitation glove  100  according to the inventive concept, unlike an existing product, may include the strap unit  220  including the first strap  121 , the second strap  122 , and the third strap  123  that are classified according to the bone parts of the finger, and may perform rehabilitation training of spreading and relaxing the hand and the fingers having spasticity one by one and completely spreading the entire palm, by the user, while different intensities are applied to the classified areas.
