Definitions

• This invention relates to the Multi-support for correction or prevention of subluxed shoulder which frequently occurs in hemiplegic stroke patients.
• the Multi-strap shoulder support for correction or prevention of subluxed shoulder shows its highest competence particularly in making the affected arm's treatment posture correct and in evenly dispersing the unavoidable pressures generated by drawing the arm upwards for reducing the subluxations present. This ensures to help the patient get along without pain and complications that come from subluxations.
• the trunkal figures of hemiplegics become scoliotic and the scapula usually rotates letting glenoid fossa head downward, which all facilitates subluxations.
• the absence or delay in shoulder muscle strength recovery may trigger even greater amount of subluxation.
• a shoulder support The purpose of a shoulder support is to prevent shoulder from becoming subluxed due to weight of the arm and muscle weakness, and to correct subluxation if it already took place.
• Various kinds of support have been introduced for the above purpose, but due to the lack of comfortness on application and technical problems, most of the health care services are using the simple arm sling(Hemi-sling or Hemi-cuff sling) up to now.
• the first type is, as shown in Fig. 8, a cuff type arm sling which is so called as Hemi-sling.
• Hemi-sling comprises a first cuff 81 to support the wrist and hand, a second cuff 82 to support the elbow, and a strap 83 whose both ends are connected with the cuffs 81 and 82 respectively.
• the strap 83 being connected with the first cuff 81 in front, crosses over the healthy shoulder, diagonally extends the back and reaches the second cuff 82.
• Hemi-sling has the advantage of simplicity in its structure and manufacturing thereof as well as easy donning and doffing.
• Hemi-sling uses only one strap in order to simultaneously suspend both the cuffs 81 and 83 in no consideration of weight difference between the wrist and the elbow, long time and/or tightly suspended application of Hemi-sling may exert an unfavorable feature .
• the comparatively lighter hand is apt to be pulled upward while the comparatively heavier elbow lagged downward, which means there isn't sufficient force for drawing the arm up, intended to attach the head of humus onto glenoid fossa of scapula.
• the second type of the arm sling is the trough type which is a modification of Hemi-sling.
• the trough type arm sling as shown in Fig. 9, comprises a cuff 91 which is so formed as to support both the wrist and the elbow simultaneously and a strap 92 whose both ends are connected with both ends of the cuff 91 respectively.
• the trough type arm sling has the same advantages of simplicity in its structure and manufacturing as well as easy donning and doffing but also reveals same disadvantages as shown in Hemi-sling.
• Another type is, being not drawn, the one which uses a vest to support the wrist and the arm respectively.
• the vest type comprises a vest to support the elbow and forearm on the whole by a first cuff, a second cuff to support the wrist and palm, and a strap to connect these cuffs with the vest.
• the vest type sling seems to be superior to the aforementioned , two types in the light that it can protect the elbow from lagging downward more efficiently than the others.
• the vest tends to shift towards the affected shoulder due to the pulling tensions from straps drawing the arm up.
• the vest type may give inconvenience or discomfort to the patient due to feeling of tightness or rather suffocation during fittings.
• Figs. 10(a) and 10(b) The last to be compared is the Harris hemi-sling as shown in Figs. 10(a) and 10(b), which consists of an elbow-enclosing pad 93, a second pad 94 beneath the wrist and hand and adjustable loops 95 enxte ⁇ ding from each of those pads to a connecting piece in the back.
• the loops extending from the elbow pad travel in front of and behind the shoulder.
• Adjustable straps hold the pads and loops together in front of the chest.
• the Harris sling can hold the elbow initially, but eventually the elbow part sags down because the back connecting piece ultimately moves to the affected side due to the uneven tensions between the two loops crossing both shoulders. Also, the Harris hemi-sling does not allow any movement of the arm at all. In case of the Multi-support of the present invention, patient can abduct and flex the shoulder and can move his/her arm freely if the two sockets in front is detached.
• An object of the present invention is to provide a Multi-support for correction or prevention of subluxed shoulder which can not only serve a good continuous rectification on subluxation with little pain and edema but also prevent recurrence thereof.
• Another object of the present invention is to provide a
• Multi-support for correction or prevention of subluxed shoulder which can evenly distribute strap's pressure.
• the Multi-strap shoulder support enables long time application without producing inconvenience from localized oppression.
• Multi-strap shoulder support for correction or prevention of subluxed shoulder according to the present invention which comprises:

• FIG. 2 is an unfolded rear view of the main part(main belt) thereof, and Fig.
• the Multi-support for correction of subluxed shoulder comprises a main belt 1 having an armpit pad part 1 1A to be positioned beneath the axilla, a back pad part 1 1B to wrap the back, and plural holding rings 451 , 452 and 453 secured on the surface of the main belt 1 ; an elbow cuff 2 to rest and support the elbow; a hand cuff 3 to rest and support the hand and the wrist; a first strap 4 to suspend the front upper edge of the elbow cuff 2, whose one end has a connecting ring 421 and the other end is removably connected with the front upper edge of the elbow cuff 2; a second strap 5 to suspend the hand cuff 3, whose one end is fixedly secured on the back pad part 1 1B and the other end being removably connected with the hand cuff 3; and a tension distributing string 45 whose one end is tied to the first
• the armpit pad part 1 1 A extends to form the back pad part 1 1B as a single body.
• the main belt 1 may further comprise a socket 121 and a hook 141 at their ends respectively.
• connecting pads 12 and 13 can be interposed therebetween for easy attachment thereof.
• the socket 121 and the hook 141 may be of conventional quick-snap connector and the connecting length between these can be naturally variable by using a conventional length adjustable strap 14 provided on the socket 12 and/or on the hook 141 , so that the Multi-strap shoulder support according to the present invention is compatible to the diversified physique.
• the connecting pads 12 or 13 and/or the length adjustable strap 14 may be partially made of elastic band in order to facilitate breathing during applying the device.
• the length L1 of the upper side of the back pad part 1 1B is so formed as to be longer than the length L2 of the lower side thereof (L1 >L2) in consideration that the human's girth becomes larger in general when measured at upper position.
• This difference of length is of service to increase the wearing comfortability since it can make not only the back pad part 1 1B mostly well suited to the back but also the movement of the armpit pad part 11A stably restricted so much.
• the main belt 1 may have an under notch-cut seam or an overlapping patch 16 at the place where the armpit pad part 1 1A meets the back pad part 1 1B, the under notch-cut seam or the overlapping patch 16 preferably forming such a concave as to smoothly gird the delicate skin of armpit, which may be another design factor to increase the wearing comfortability and stability.
• This provides an angulated surface facing the torso on affected side of the trunk ; allowing more contact with the torso beneath axilla, and a structure that surrounds the lower scapular region more smoothly.
• 1 IB can be accomplished by an initial design thereof without any notch-cut seam or overlapping patch.
• the back pad part 1 1B is so formed as to be slanted from the affected shoulder axilla to the healthy one as well shown in Figs. 2 and 4.
• the elbow cuff 2 to rest and support the elbow forms a trough whose front side and upper side are opened.
• Outward protrusion of the elbow through the opening 23 helps to reduce the supporting pressure elbow receives from the elbow cuff 2 when the elbow is rested thereon and the opening 23 also helps to prevent the elbow from being easily slipped off from the elbow cuff 2.
• the hand cuff 3 to rest and support the wrist and/or the palm forms a trough whose front, rear and upper sides are opened.
• connection straps 31 and 32 On the rear upper edge and on the front upper edge of the hand cuff 3 are connected a couple of hand cuff connection straps 31 and 32 respectively which have a common connection socket 31 1 on their top.
• the length of the strap 31 positioned near the fingertips preferably needs to be shorter than that of the strap 32 positioned near the wrist so as to give the supported palm a comfortable resting posture without wrist being flexed and to prevent hand edema occured by position of fingers heading down.
• the first strap 4 may comprise a shoulder pad 41 on its way whose width W4 is preferably wider than the width W3 of the first strap itself (W3>W4) in order to more effectively, widely distribute the pressure acting on the affected shoulder when the first strap 4 suspends the arm.
• the shoulder pad 41 needs not to be provided.
• the shoulder pad 41 may be so composed as to be position- adjustable along the length of the first strap 4.
• the front end of the first strap 4 is removably connected to the second elbow cuff connection strap 22 by means of a couple of connector, the socket 221 and the hook 411.
• the rear end of the first strap 4 has no conventional quick-snap connector but a connecting means such as a ring 421 through which the tension distributing string 45 passes, so that the rear end of the first strap 4 is pressure-control lably suspended on the back pad part 1 1B by means of the tension distributing string 45.
• Fig. 2 which shows the unfolded rear view of the Multi-support for correction of subluxed shoulder according to the present invention
• the one end of the tension distributing string 45 is tied to the holding ring 451 secured preferably on the back pad part 1 1B of unaffected side and the other end passes through the connecting ring 421 secured on the rear end of the first strap 4 and another holding ring 452 secured on the back pad part 1 IB in order, and then is fastened to the other holding ring 453 secured preferably on the armpit pad part 11 A.
• the tension beared in the tension distributing string 45, particularly, between the holding rings 452 and 453 is converted into compressing force which makes the back pad part 1 1B adhere toward the torso that helps prevent the main belt 1 from being drifted or pulled upward.
• the illustrated embodiment of the present invention has three holding rings 451 , 452 and 453, it should be noted that the number of holding rings to be secured on the main belt 1 and how to bifurcate or trifurcate the passing or suspending course of the tension distribution string 45 when the string 45 is connected with the first strap 4 have to be construed not to influence upon the scope of the invention ; provided that the main belt 1 has two or more holding points thereon in order for the string 45 to work the arm supporting pressure of the first strap 4 into being dispersed over the main belt 1.
• the fixing or holding length of the tension distribution string 45 in connection with the first strap 4 can be variably adjusted in careful consideration of the condition of the affected shoulder or physical difference of the patient and the string 45 can be supported at remoted plural points of the back pad part 1 1B.
• the pressure distribution efficiency of the Multi-strap shoulder support according to the present invention is more excellent than any other previous supports.
• the Multi-strap shoulder support for correction of subluxed shoulder may further comprise an auxiliary strap 43 whose rear end is fixedly secured on the back pad part 1 1B and whose front end is removably connected with the rear upper end of the elbow cuff 2.
• the auxiliary strap 43 is particularly useful to adopt to the obese or muscular patients with heavy arm.
• the auxiliary strap 43 it is preferable that on the shoulder pad 41 has a bypassing ring 422 thereon where the auxiliary strap 43 can make its turning point to form a peak on the back, and so it can run down along the outside of the affected upper arm. That is, the auxiliary strap 43, as well shown in Fig. 4, one end of which is fixed on the back pad part 1 1B of the unaffected side, extends upward to the shoulder pad 41 which is normally mounted on the affected shoulder and passes through the bypassing ring 422 and runs down along the outside of the affected upper arm and then is removably connected to the rear upper end of the elbow cuff 2.
• the front end of the auxiliary strap has a length adjustable hook 431 to match the socket 21 1.
• the weight of the affected arm can be mostly supported by the first strap 4, but when adopted the auxiliary strap 43, the pressure distribution capability of the system becomes more increased as well as the supporting condition as to both the elbow and the hand becomes more stable so much.
• the second strap 5 may also comprise a position-shiftable shoulder pad 52 thereon.
• a conventional length adjustable quick-snap hook 51 1 to match the socket 31 1 is provided at the front end of the second strap 5.
• the main belt 1 is preferably composed of three layers of different materials; a thin leather cover on the upper(outer) surface, an about 0.5 mm-thick polyethylene lining and a foamy rubber-cotton mixture textile on the bottom(inner) surface.
• the main belt 1 should not be too thick but should be stiff enough to resist distortions on applications and that is why polyethylene plate is desirably adopted.
• the shoulder pad 41 bears most of the arm supporting tension, the shoulder pad is preferably made of about 0.5cm-1 cm thick foamy rubber.
• the present inventor has tested the correction effects on subluxed shoulders by orthoses including the Multi-support(present invention), the Rolyan hemi-cuff sling(comparative 1 ), the Bobath roll(comparative2) and the Hemi-cuff sling(comparative 3).
• the CVD and the CHD mean the corrected amount of VD and HD respectively when the result of applying orthoses is compared to the result of no applying orthoses.
• the Multi-strap shoulder support for correcting subluxed shoulders shows excellent correction effect on subluxation when compared with other supports, particularly, on the vertical distance between the acromial processes and the humeral heads.
• the Multi-strap shoulder support according to the present invention seems to be somewhat complicated at a superficial glance and is more difficult and stuffy to wear than Hemi-sling.
• the present inventor as a physiatrist who has observed many patients with subluxation can certainly say that most patients with subluxation willing to wear the Multi-strap shoulder support of the present invention instead of the Hemi-sling because they could feel edema and/or pain lessen and, at the same time, feel more comfortable and stable with it.
• 4 points can be arranged as follows.
• the supporting system where the front part and the rear part of the elbow are double-supported by dependant straps 4 and 43 (22 and 21 ) respectively and the elbow and the hand are also double-supported by dependant straps 4 and 5 respectively and, further, the hand and the wrist are double-supported by the straps 31 and 32 with a little difference in their supporting lengths which all provides a stable position of arm and hand, and also a position in which the elbow-to-hand makes a gradual upward tilt in order to prevent pain and edema.
• the straps' pressures which might have distracted patients by oppressing on focal regions with other supports were managed to be distributed evenly over the wide surface area of the main belt 1.
• Multi-strap shoulder support can be separated with ease and donning and doffing thereof is convenient rather than thought.
• the excellent correction effect of the support according to the present invention deserves to willingly endure the initial wearing trouble if any.
