SHOULDER BRACE WITH BODY TO ARM
ATTACHMENT STRAPS
FIELD OF THE INVENTION
The present invention relates to a shoulder complex and upper arm
injury reduction system. The system is particularly useful for athletes in
contact sports.
BACKGROUND OF THE INVENTION
Dating back to 1988, I patented an injury reduction and stabilizing
harness as described in my United States Patent 4,735,198. According to my
earlier patent, I used elastic straps on a torso and upper arm fitting harness
to
control the amount of movement of the upper arm relative to the torso of the
user. The straps, according to my earlier patent, attached at their opposite
ends
by Velcro' ~' to different part of the harness.
My earlier patented harness allowed athletes or even people under
2 o general rehabilitation continued controlled use of an injured shoulder or
upper
arm. The elasticity of the straps, particularly once the straps are stretched,
would slow movement of the injured body part rather than allowing the body
part completely unrestricted free motion.
2 5 Since the time of my earlier patent, many athletes in professional
sports have grown much bigger and much stronger. Consider the size of a
lineman on a pro football team who will easily weight in excess of 300 pounds.
Today's professional hockey players usually weight in excess of 200 pounds
which is probably some 20 to 30 pounds heavier than the players in the 1980s.
3 o It is well accepted that athletes of the 21 s' century are much larger,
stronger and
faster than their counterparts of the 1980s. As such, the harness as described
in
my 1988 patent, although providing extremely beneficial results at the time,
is
not capable of standing up to the tremendous physical punishment encountered
by the larger athletes of the present.

SUMMARY OF THE INVENTION
The present invention provides a shoulder complex and upper arm
injury reduction system. The system of the present invention comprises a torso
fitting part, an upper arm wrap part and at least one movement control strap.
That strap has a first strap region which is secured by an anchor fixed at the
torso fitting part and a second strap region which is anchored at the upper
arm
wrap part.
The strap itself is adjustable to different strap lengths between the
1 o first and second strap regions. The length to which the strap is adjusted
sets the
amount of movement of the upper arm wrap part relative to the torso fitting
part. The strap is made from an essentially inelastic material such that the
strap
prevents separation of the upper arm wrap part from the torso fitting part
beyond the strap length to which the strap is adjusted.
According to another aspect of the present invention, the torso fitting
part includes a shoulder capping region and a control strap which extends from
the shoulder capping region to a strap mounting location below the shoulder
capping region. Alternatively, the strap can extend from a location below the
2 o shoulder capping region to a strap mounting location above the shoulder
capping region. The strap is length adjustable to allow tension to be placed
on
the strap and to produce traction within the system between the shoulder
strapping region and the strap mounting location.
2 5 The key to the present invention lies in the use of length adjustable,
essentially non-stretch straps, which can be fixedly anchored in position on
the
system. Through the use of these three features, the straps, while allowing a
controlled limited movement of the upper arm wrap part relative to the torso
fitting part, are strong enough to control even the biggest and strongest
athlete
3 o from moving beyond a desired range of motion set by the control straps.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
2 o EMBODIMENTS OF THE PRESENT INVENTION
Figure 1 shows a shoulder complex and upper arm injury reduction
system generally indicated at 1. This system is based on a corset like member
comprising a torso fitting part 3 and an upper arm wrap part 5. The torso
fitting part 3 and the upper arm wrap part 5, in the embodiment shown in
25 Figure l, are part of a one piece corset provided with an underarm cutout
6.
This underarm cutout allows movement of the upper arm wrap part S relative to
the torso fitting part 3 without chaffing in the underarm region.
Torso fitting part 3 includes a side closure 1 1 which allows the entire
3 o corset to be opened for fitting on to the user including the fitting of
the upper
arm through part 5. Side closure 1 l, which is preferably a Velcro'"~closure,
can then be secured to hold the overall corset tightly wrapped on the body of
the user.
3 5 Upper arm wrap part 5 preferably includes a side closure which
allows the entire upper arm wrap part to be opened for fitting on to the arm
of
the user. The side closure, which is preferably a Velcro'M closure, can then
be
CA 02491509 2005-O1-05
122120
-S-
secured to hold the upper arm wrap tightly wrapped on the arm of the user.
The side closure also allows different arm sizes to be accommodated.
Both the torso fitting part 3 and the upper arm wrap part S are
s preferably made from a rubbery stretch material such as neoprene or the
like.
This type of material is light in weight, hugs neatly to the user, and
provides
body warmth which is particularly useful if the system is being used with a
previously injured body part. Even if there is no previous injury, the warmth,
i.e. blood flow, induced by the neoprene or similar material helps to prevent
an
1 o injury to the user. In addition, it can be appreciated that a stretchy
blended
cotton material or stretchy blended synthetic material, which is breathable,
flexible and strong, can also be used for the torso fitting part 3 and the
upper
arm wrap part S. However, this is not limiting and other materials are
considered within the scope of the invention.
A certain amount of stability is desired in the torso fitting part 3 so
that it does not overstretch and move around while fitted to the user. To this
end, flexible stabilizer bars 7 and 9 are secured, as by stitching for
example, to
the stretch material of the torso fitting part 3. Figure 2 of the drawings
shows
2 o that further flexible stabilizer bars 27, 29 and 31 are provided on the
rear
surface of the torso fitting part 3.
The system described thus far is similar to what was disclosed in
United States Patent 4,735,198. However, substantial differences between the
two systems as provided in the present invention will now be further
described.
Torso fitting part 3 is provided with a series of rigid buckles 13, 1 S
and 17. These buckles are held in place by small non-stretchable anchoring
straps 14, 16 and 18 respectively. A further buckle 19 is secured by anchoring
3 o strap 20 to the front side of the torso fitting part 3. The inclusion of
the
anchoring straps, which are permanently fastened to the torso fitting part 3,
allow the buckles some freedom of movement outwardly away from the torso
fitting part 3. This in turn allows for easy fitting of control straps, to be
described later in detail, to be fitted through the buckles. Preferably, the
3 5 anchoring straps 14, 16, 18, and 20 are permanently fastened to a location
on
the stabilizer bar 9 to provide greater stability and strength to the system.

-6-
In one preferred embodiment of the invention, provided on the upper
arm wrap part 5 is a further rigid buckle 23 anchored or held fast on the
upper
arm wrap part 5 by a non-stretchable anchoring strap 24. Once again, the
purpose of anchoring strap 24 is simply to remove buckle 23 far enough away
from the surface of the upper arm wrap part 5 to accommodate the fitting of a
control strap through the buckle.
Now turning to Figure 2, further rigid buckles 33 and 35, which are
secured by non-stretchable anchoring straps 34 and 36 respectively, are
1 o provided to the backside of the torso fitting part 3. A further rigid
buckle 39,
which is secured by non-stretchable anchoring strap 40, is provided on the
backside of torso fitting part 3, as shown in Figure 2. The inclusion of the
anchoring straps, which are permanently fastened to the torso fitting part 3,
allow the buckles some freedom of movement outwardly away from the torso
fitting part 3. This in turn allows easy fitting of control straps, to be
described
later in detail, to be fitted through the buckles. Preferably, the anchoring
straps 34, 36, and 40 are permanently fastened to locations on the stabilizer
bar
to provide greater stability and strength to the system.
2 o In one embodiment of the invention, a further rigid buckle 37, which
is secured by non-stretchable anchoring strap 38, is provided on the backside
of
torso fitting part 3, as shown in Figure 4. Once again, the purpose of
anchoring strap 38 is simply to remove buckle 37 far enough away from the
surface of the upper arm wrap part 5 to accommodate the fitting of a control
2 5 strap through the buckle.
Preferably anchoring straps 14, 16, 18, 20, 24, 34, 36, 38, and 40 are
made from a material such as a woven nylon which is essentially stretch free.
Such a material is also resistant to deterioration which might otherwise be
3 o caused by body sweat over the life of the system.
One of the keys to the present invention resides in the essentially
immoveable location of the buckles on the system and the use of non-elastic,
i.e. essentially stretch free, control straps, to be described later in
detail, for
3 5 controlling movement of the upper arm wrap part 5 relative to the torso
fitting
part 3 of the system 1.
CA 02491509 2005-O1-05
12212CA
Provided on upper arm wrap part 5 is an elongated Velcro~~'" surface
member ~ 1. This Velcror'" member 21 encircles most, if not all, of the
outside
surface of the upper arm wrap part 5 near its lower end as shown in Figures 1
and 2.
Further provided on upper arm wrap part 5 is a second VelcroT"'
surface member 22, which extends upwardly along the length of upper arm
wrap part 5. Located directly over the shoulder capping region of upper arm
wrap part 5 is a strap trapping loop 25.
to
To control movement of the upper arm wrap part 5 relative to the
torso fitting part 3 of the system 1, at least one movement control strap 43
is
provided. The control strap 43 is preferably made from an inelastic non-
stretch material, such as woven nylon, and is anchored to the upper arm wrap
part 5 and to the torso fitting part 3 such that the control strap 43
restricts and
controls the amount and degree of posterior and anterior movement of the
upper arm wrap part 5 from the torso fitting part 3 beyond the length of the
strap, which length is adjustable as described later in detail, and to
restrict and
control multidirectional movements of the upper arm wrap part 5 from the torso
2 o fitting part 3 beyond the length of the strap, which length is adjustable
as
described later in detail.
In a preferred embodiment of the invention, the system 1 utilizes a
series of control straps as illustrated in Figures 1 and 2. In this preferred
2 s arrangement, the control straps 43a, 43b, 43c, and 43d are of varying
lengths,
wherein each control strap has a first strap end region 45 and a second strap
end region 47, which anchors to the torso fitting part 3 and the upper arm
fitting part 5, as described later in detail.
3 o Control strap 43a restricts the rearward movement of the upper arm
wrap part 5 relative to the torso fitting part 3, and thus provides the
capability
of preventing movement of the shoulder joint into a position in which it could
dislocate. In one aspect of the invention, the first strap end region 45 of
control
strap 43a is threaded through buckle 13, and is folded back over buckle 13 to
3 s form a first loop part 49. The first loop part 49 includes an interlocking
Velcro~~' surface region 51 to secure the first strap end region 45 to buckle
13.
The second strap end region 47 of control strap 43a is threaded through buckle
CA 02491509 2005-O1-05
12212CA
_g_
23, and is folded back over buckle 23 to form a second loop part 53. The
second loop part 53 includes an interlocking Velcro~~' surface region 55 to
secure the second strap end region to buckle 23. By adjusting the first loop
part 49 and the second loop part 53, different strap lengths, which correspond
to different ranges of movement, can be utilized.
Similarly, control strap 43d provides the capability of restricting the
forward movement of the upper arm wrap 5 relative to the torso fitting part 3.
In one aspect of the invention as illustrated in Figure 2, the first strap end
1 o region 45 of control strap 43d is threaded through buckle 35, and is
folded back
over buckle 35 to form a first loop part 49. The first loop part 49 includes
an
interlocking Velcror~' surface region 51 to secure the first strap end region
45 to
buckle 35. The second strap end region 47 of control strap 43d is threaded
through buckle 37, and is folded back over buckle 37 to form a second loop
part 53. The second loop part 53 includes an interlocking VelcroT"~ surface
region 55 to secure the second strap end region 47 to buckle 37. By adjusting
the first loop part 49 and the second loop part 53, different strap lengths,
which
correspond to different ranges of movement, can be utilized.
2 o In an alternate embodiment, one of either the first strap end region
45 or the second strap end region 47 of control straps 43a and 43d is
permanently attached to the torso fitting part 3 or the upper arm wrap part 5
respectively. Adjustments to the length of the control strap are made at the
unfixed strap end region, which is threaded through a buckle and folded back
2 5 over the buckle to form a loop part and secured using interlocking
VelcroT"'
surface regions as described above. For example, as illustrated in Figure 2,
the
second strap end region 47 of control strap 43d is permanently secured to the
upper arm wrap part 5, and adjustment of the length of the control strap is
made
by adjusting the first loop part 49 of the frst strap end region 45.
In a further alternate embodiment as illustrated in Figures 3, 4, and 8,
forward and rearward movement of the upper arm wrap part 5 is controlled by
a single control strap 43e. In this embodiment, the first strap end region 45
of
control strap 43e is threaded through buckle 23, and is folded back over
buckle
3 5 23 to form a first loop part 49. The first loop part 49 includes an
interlocking
Velcro"' surface region 51 to secure the first strap region 45 to buckle 23.
The
second strap end region 47 of control strap 43e is threaded through buckle 37,
CA 02491509 2005-O1-05
12212CA
-9-
and is folded back over buckle 37 to form a second loop part 53. The second
loop part 53 includes an interlocking VelcroTM surface region 55 to secure the
second strap region to buckle 37. Control strap 43e is positioned to encircle
the torso, and is threaded through buckle 13 to prevent slippage of the
encircling position of control strap 43e. By adjusting the first loop part 49
and
the second loop part 53, different strap lengths, which correspond to
different
ranges of movements, is achieved.
Control straps 43a, 43d, and 43e are designed to restrict the forward
1 o and rearward movement of the upper arm wrap part 5, and thereby
restricting
the forward and rearward movement of the shoulder joint and preventing the
shoulder joint from moving into a position in which it could dislocate.
Control strap 43b controls the multidirectional movement of the
1 s upper arm wrap part 5 relative to the torso fitting part 3. In a preferred
embodiment, control strap 43b is of an extended length wherein the first strap
end region 45 is anchored at the front side of the torso fitting part 3, and
the
second strap end region 47 is anchored at the rear side of the torso fitting
part
5. As illustrated in Figures 1 and 2, control strap 43b is positioned to
encircle
2 o both the torso fitting part 3 and the upper arm wrap part 5, wherein a
segment
of control strap 43b is secured to Velcro"' member 21. In addition, control
strap 43b is permanently affixed together, preferably by stitching, at a
location
57 between the torso fitting part 3 and the upper arm wrap part 5.
2 s The first strap end region 45 of control strap 43b is threaded through
buckle 15, and is folded back over buckle 15 to form a first loop part 49. The
first loop part 49 includes an interlocking VelcroT"~ surface region 51 to
secure
the first strap end region 45 to buckle 15. The second strap region 47 of
control strap 43b is threaded through buckle 33, and is folded back over
buckle
3 0 43 to form a second loop part 53. The second loop part 53 includes an
interlocking Velcro's' surface region 55 to secure the second strap end region
47 to buckle 33. By adjusting the first loop part 49 and the second loop part
53, different strap lengths for control strap 43b is achieved. In particular,
the
stitching at location 57 allows for independent adjustment of the front
portion
3 s of control strap 43b, located on the front side of the torso fitting part
3, and of
the rear portion of control strap 43b , located on the rear side of the torso
fitting
part 3. Thus, this preferred arrangement of control strap 43b controls the
CA 02491509 2005-O1-05
12212CA
- 10-
multidirectional movement of the arm, including flexion and extension of the
arm, internal and external rotation of the arm, and all combinations thereof.
This is particularly useful for shoulders that are unstable in all directions
of
movement. Furthermore, stitching at location S7 also prevents control strap
43b from tangling and catching.
In an alternate embodiment of the invention [not shown], control
strap 43b is preferably comprised of two identical straps 43bb and 43bbb,
wherein control strap 43bb is positioned on the front side of torso fitting
part 3
1 o and control strap 43bbb is positioned on the rear side of torso fitting
part 3.
The first strap end region 4S of control strap 43bb is threaded through buckle
1 S, and is folded back over buckle 1 S to form a first loop part 49. The
first
loop part 49 includes an interlocking VelcroT"' surface region S 1 to secure
the
first strap end region 4S to buckle 1 S. The second strap end region 47 of
15 control strap 43b, which includes an interlocking VelcroT"" surface region
SS, is
wrapped around and secured to VelcroT"' member 21. The first strap end
region 4S of control strap 43bbb is threaded through buckle 33, and is folded
back over buckle 33 to form a first loop part 49. The first loop part 49
includes an interlocking Velero~M surface region S I to secure the first strap
end
2 o region 4S to buckle 33. The second strap end region 47 of control strap
43bbb,
which includes an interlocking VelcroT"' surface region SS, is wrapped around
and secured to VelcroT"' member 21. Control straps 43bb and 43bbb are
permanently affixed together, preferably by stitching, at a location S7
between
the torso fitting part 3 and the upper arm wrap part S. This alternate
2 5 embodiment of control strap 43b al lows different arm sizes to be
accommodated.
Control strap 43c provides tension to the acromioclavicular (A/C)
joint when there is interruption of the acromioclavicular ligaments, i.e. the
3 o conoid and trapezoid, and the coracoacromial ligaments. The degree of
sprain
or tear can vary from 0% to 100% disruption of these ligaments. Control strap
43c is positioned over the acromioclavicular joint to provide a splint-like
application to provide stability while the acromioclavicular joint heals.
Furthermore, the action of the control strap 43c will help to reduce pain,
3 s minimize soft tissue scarring and help promote a normal range of motion.
Control strap 43c is anchored from a point on the front side of the torso
fitting
part 3, and extends over the shoulder capping region through strap trapping
CA 02491509 2005-O1-05
12212CA
-11-
loop 25, and anchored to the rear side of the torso fitting part 3. In a
preferred
embodiment as illustrated in Figures I and 2, the first strap end region 45 of
control strap 43c is threaded through buckle 19, and is folded back over
buckle
19 to form a first loop part 49. The first loop part 49 includes an
interlocking
s Velcro'' surface region 51 to secure the first strap end region 45 to buckle
19.
The second strap end region 47 of control strap 43c is threaded through buckle
39, and is folded back over buckle 39 to form a second loop part 53. The
second loop part 53 includes an interlocking Velcro'"' surface region 55 to
secure the second strap end region 47 to buckle 39. Strap trapping loop 25
1 o maintains the positioning of the control strap 43c, and prevents slippage
of the
control strap 43c.
In an alternate embodiment of the invention, one of either the first
strap end region 45 or the second strap end region 47 of control strap 43c is
1 s anchored directly to the torso fitting part 3, and preferably affixed
together with
a stabilizer bar on the torso fitting part 3.
In an alternate embodiment as illustrated in Figures 11 and 12, the
control strap 43c extends from the chest region of the torso fitting part 3 to
a
2 0 location on the rear of the torso fitting part 3. In this embodiment,
control
strap 43c is anchored to a strap mounting location on the chest portion of the
torso fitting part 3. The first strap end region and second strap end region
of
control strap 43c are anchored to adjustment anchors 59 permanently affixed to
the torso fitting part 3. The strap end region of the control strap 43c is
25 threaded through the adjustment anchor 59, and is folded back over
adjustment
anchor 59 to form a loop part, wherein the interlocking VelcroT"~ surface
region
51 secures the strap end region to the adjustment anchor 59.
Furthermore, to avoid undue pressure on the injured shoulder joint as
3 o a result of the force and tension of the control strap 43c, a high density
pad 84
is removeably positioned beneath control strap 43c over the acromioclavicular
joint, to be described later in detail. To ensure the correct positioning of
the
pad 84, a pad insertion pocket 68 is utilized for removeably receiving a pad
84.
The pad insertion pocket 68 is preferably positioned over the
acromioclavicular
3 5 joint, as illustrated in Figures 14 and 15.

Control strap 43d is provided to allow further adjustments of the
torso f tong part 3 to accommodate different torso widths. Control strap 43d
permits the tightening of the lower part of the torso fitting part 3 to
increase the
fit of the torso fitting part 3 and to prevent the torso fitting part 3 from
rising
s up. The first strap end region 4S of control strap 43c is threaded through
buckle 17, and is folded back over buckle 17 to form a first loop part 49. The
first loop part 49 includes an interlocking Velcror"~ surface region S 1 to
secure
the first strap end region 4S to buckle 17. The second strap end region S3 is
preferably permanently secured to the torso fitting part 3.
It can also be appreciated that the number of control straps used in
the system 1 can be customized to accommodate the specific injuries and needs
of the user. When all the control straps 43as illustrated in Figures 1 and 2
are
used, the system 1 can restrict and limit posterior and anterior movement of
the
shoulder, as well as multidirectional movement of the shoulder.
It can be appreciated that by adjusting the first loop part 49 and/or
the second loop part S3 of control straps 43, the length of each control strap
is
independently adjusted. The adjustments are easily and simply done. The
2 o adjustability of the control straps allows the user to selectively
customize the
range of movement of the shoulder. Thus, the adjustability of the control
straps 43 allows the shoulder complex and upper arm injury reduction system 1
to be used throughout the duration of rehabilitation, as a wide range of
motions
can be achieved: from holding the shoulder completely immobile to allowing
2 s motion of the shoulder in limited specific directions. The degree of
mobility
of the system 1 can be adjusted to accommodate the regained mobility of the
user's shoulder.
Figures 3, 4, and 7 further demonstrate the principals of the
3 o invention. Within the permitted range of motion as set by the length of
the
control straps 43, there is complete mobility of the arm and shoulder region.
However, movement of the arm and shoulder beyond the length of the control
straps 43 is prevented by the inelastic material of the straps.
3 s It can be appreciated that the principals of the invention can be used
to modify existing athletic equipment to accommodate injured athletes. In
particular, this is useful because athletes will not be required to wear a
separate
CA 02491509 2005-O1-05
12212CA
- 13-
brace beneath their equipment. As illustrated in Figures 5 and 6, the
principles
of the shoulder complex and upper arm injury reduction system 1 is
incorporated into an athletic shoulder pad. Control straps 43 are anchored or
fixed directly to the shoulder pads at one end, and adjustments to the length
of
s the control strap is made at the other end. However, this example is not
limiting and other athletic equipment can be modified and are considered
within the scope of the invention.
In a further aspect of the invention, the shoulder complex and upper
1 o arm injury reduction system 1 includes a control strap 60. In this
embodiment,
as illustrated in Figures 9 and 10, it is preferable that the upper arm wrap
part 5
fit snugly around the upper arm region. The first surface of control strap 60
comprises at least one interlocking VelcroT"' surface region to secure
traction
strap 60 to Velcro"' surface member 22 on upper arm wrap part 5. The upper
1 s arm wrap part 5 further comprises an adjustment anchor 64, and a pad
insertion
pocket 68. Control strap 60 further comprises an end region with a VelcroT~'
surface region 76.
Control strap 60 is preferably made from an inelastic non-stretch
2 o material, such as woven nylon. Control strap 60 is preferably comprised of
a
single piece of material, however, it can be appreciated that control strap 60
can be comprised of at least one interconnecting pieces of material.
The end region of the control strap 60 is threaded through the
25 adjustment anchor 64, and is folded back over adjustment anchor 64 to form
a
loop part 80 wherein the VelcroT~' surface region 76 attaches to a VelcroT~'
receiving region 78. The control strap 60 provides traction and upward lift of
the arm so as to approximate the humerus and glenoid labrum and capsule of
gleno-humeral. Controlling the level of traction can be controlled through the
3 o adjustment of control strap 60.

As illustrated in Figures 14 and 15, to avoid undue pressure on the
injured shoulder joint as a result of the force and tension of the control
strap 60
or control strap 43c, a pad 84 is removeably placed in the pad insertion
pocket
68, wherein the pad insertion pocket 68 and the pad 84 are located directly
over
the acromioclavicular joint. Pad 84 is preferably made from a high density
material to allow the pad to absorb the force created by the control strap.
As illustrated in Figure 13, to avoid undue direct pressure on the
acromioclavicular joint, the pad 84 is shaped to avoid direct contact with the
1 o acromioclavicular joint and to contact the area immediately surrounding
the
acromioclavicular joint. It can be appreciated that the pad 84 can be provided
in a variety of shapes, and the pad 84 is preferably shaped in a C-shape 84a,
or
in a ring of hexagons 84b.
Although the invention has been described with respect to specific
preferred embodiments, it should be appreciated that other embodiments
utilizing the concept of the present invention are possible without departing
from the scope of the invention. The invention is not intended to be limited
to
the specific embodiments.
