Description
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 10/798,205, filed Mar. 11, 2004, which is
incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
[0002] present invention relates to a device for stretching the
plantar fascia of the foot and associated structures.
BACKGROUND OF THE INVENTION
[0003] A number of different maladies affecting the lower
extremities exist that could be treated by stretching or exercising
the specific tissues involved. These maladies include plantar
fasciitis, Achilles tendonitis, Gastrocsoleus Equinus, shin
splints, club foot, drop foot, fibromyalgia, etc. The discussion on
this invention will focus specifically on plantar fasciitis,
realizing that the present invention may be used for stretching
many structures associated with the foot, either directly connected
to the foot or structures not physically connected to the foot, but
structures that may be stretched by stretching the foot. Exemplary
structures directly associated with the foot include the plantar
fascia, Achilles Tendon and the gastroc/solius muscle complex.
Additional exemplary structures associated with the foot, but not
physically connected to the foot that may also be stretched using
the present invention include the hamstring, and/or gluteous
maximus and the like.
[0004] The plantar fascia is a fibrous tissue that spans between
the medial tubercle of the calcaneus (or heel bone) to the
metatarsals (or toe bones). When a person stands, the plantar
fascia is stretched under the load of the person's weight. This is
known as the "bowstring effect." Should the toes and ankle be
dorsiflexed (or hyperextended upward toward the shin) the plantar
fascia is stretched even further. This is called the "windlass
effect."
[0005] Plantar fasciitis is a condition that occurs to a wide range
of the adult population. It is seen in both sedentary and active
individuals. The cause of plantar fasciitis is unclear; however, a
common theory is that the plantar fascia is repetitively injured
causing partial tears and chronic inflammation. As these micro
tears heal, scar tissue forms reducing the elasticity of the
plantar fascia and contributing to further tearing and
inflammation.
[0006] Prolonged standing, obesity, pronation of the foot while
walking, running, jumping and other activities can cause repeated
injuries to the origin of the plantar fascia at its insertion on
the medial tubercle of the calcaneus of the foot. The injuries
result in the repetitive tearing of tissue, inflammation, and the
formation of scar tissue in the plantar fascia causing limitation
in flexibility. The injury causes intense pain in the bottom of the
foot near the heel. When suffering from injury to the plantar
fascia, one often incurs the greatest pain in the morning when
arising from bed because the plantar fascia has not been exercised
during the night and has become stiff and retracted as a result of
the long period of inactivity. When one rises from bed and first
applies full body weight to his or her feet, the plantar fascia is
suddenly stretched resulting in sharp pains to the heel. Studies
have shown it is desirable to gradually exercise the plantar fascia
by dorsiflexing the toes and ankles, stretching it gradually,
especially before one first applies one's body weight to his or her
feet.
[0007] Some doctors advise their patients who suffer from such
injuries to roll a towel and grasp the ends in each hand and press
the toes of the injured foot against the center of the towel while
using one's arms to pull against the towel to thereby stretch the
plantar fascia. The exercise is marginally successful because the
patient must stiffen his toes to grip the towel and prevent it from
sliding off the end of this foot. The exercise, therefore, requires
the flexing of the plantar fascia, and the plantar fascia is not
stretched as is needed. For some maladies of the lower extremities,
for example, weakness of the gastrocsoleus complex, the present
invention may be used to strengthen the gastrocsoleus complex by
having the patient resist the stretch by plantar flexing during
stretching with the present invention.
[0008] Several devices have been proposed for stretching the
plantar fascia, but such devices suffer from some of the same
limitations incurred with the towel namely, the device will not
stay affixed to the foot in such a manner as to permit the foot to
relax and thereby maximize the stretching of the plantar
fascia.
[0009] Other devices require weight bearing stretching that provide
a stretch to the plantar fascia only after the additional micro
tears have occurred from the individual standing. Still other
devices offer passive stretching of the plantar fascia. These
devices require that sufferer to wear bulky splints while they
sleep. Patient compliance is low due to the uncomfortable feeling
inherent with these devices. In addition, these devices are
incapable of achieving the same degree of dorsiflexion as can be
achieved by the present invention.
SUMMARY OF THE INVENTION
[0010] Briefly, the present invention is embodied in an exercise
device for exercising at least one structure associated with the
foot. In one aspect of the present invention, the device includes a
first member that is positionable under the toes of the patient's
foot and an attachment member connectable to the patient above the
patient's foot. The attachment member is operably connected to the
first member by a first line connected to the attachment member and
the first member. A spacer is connected to the first member and the
attachment member for retaining the attachment member in position
relative to the first member.
[0011] In another aspect of the present invention, a device for
exercising at least one structure associated with the foot is
provided. The device includes a first member positionable under
toes of the foot and a second member positionable under a ball of
the foot. An attachment member is connectable to the patient above
the foot and the attachment member is operably connected to the
first member by a first line connected to the attachment member and
at least one of the first member and the second member. Pulling the
first line and the second line stretches the plantar fascia.
[0012] In another aspect of the present invention, a method of
stretching at least one structure associated with a foot is
provided. The method includes providing a first member and
positioning the first member under the patient's toes and providing
a second member and positioning the second member under a ball of
the foot. The method further includes providing an attachment
member in a position above the patient's foot and providing a fist
line connecting the first member to the attachment member. Pulling
on the first line stretches the plantar fascia.
[0013] Advantages of the present invention will become more
apparent to those skilled in the art from the following description
of the preferred embodiments of the invention which have been shown

DETAILED DESCRIPTION
[0027] Referring to FIGS. 3 and 5, the plantar fascia 10 is a thick
fibrous band of tissue running along the bottom of the foot from
the heel to the base of the toes. When placed under too much
stress, the plantar fascia becomes stretched too far causing minute
tears within the fascia causing inflammation in the fascia and in
the surrounding tissue. The tears are soon covered with a scar
tissue, but the scar tissue is less flexible than healthy tissue
and the scar tissue tends to aggravate the problem. The injury is
called plantar fasciitis and is often most severe and most painful
in the morning when one gets out of bed or at the beginning of a
run. This is because during the night or prior to exercising, the
plantar fascia has become contracted and stiff and the sudden
stretching of the plantar fascia, caused by applying weight to the
foot in the morning, or at the beginning a run, stretches the
plantar fascia unduly and aggravates the injured portions of the
tissue.
[0028] The plantar fascia attaches at three points 12, 13, 14 to
the heel of the foot 16 and at five point 18, 19, 20, 21, 22 to
each of the five toes of the foot. Stretching the plantar fascia
can be accomplished by drawing the ball of the foot towards the
pelvis to stretch the central portion of the plantar fascia and the
portion near the heel, and by drawing the toes toward the ankle to
stretch the portion near the toes.
[0029] Referring to FIGS. 1, 2, 4 and 6, a device 24 is provided to
stretch the plantar fascia 10 and includes a first strap 26 that is
positionable under the ball 28 of the foot, a second strap 30
positionable under the toes 32 of the foot, a third strap 34 having
an eye 36 attached thereto for extending around the ankle 38, a
first line 40 attachable to the first strap 26 and a second line 42
attachable to the second strap 30. The first, second, and third
straps 26, 30, 34 are preferably made of a durable, flexible,
comfortable material such as canvas.
[0030] To provide a rigid surface under the ball 28 of the foot 16
a plate 44 is provided having a generally planar central portion
and curved outer end portions 46, 48, the curved portions 46, 48
spaced sufficiently far apart for the central portion of the plate
44 to extend across the width of the largest foot to which the
device 24 is to be attachable. The plate 44 may be made from metal,
plastic, or any other rigid materials known to one skilled in the
art. The plate 44 may be sized and shaped and have sufficient
rigidity to reduce squeezing of the foot 16 when the device 24 is
pulled as described below. The plate 44 extends through a loop of
fabric at one end of a generally rectangularly shaped retainer 50.
The retainer 50 retains the plate 44 in its desired orientation
across the ball 28 of the foot by adjustably connecting to the
second strap 30 by means of a hook and loop connector one portion
52 of which is attached to a surface of the retainer 50 and the
second portion 54 of the hook and loop is attached to a mated
surface of the second strap 30. The first strap 26 is sized to fit
around the ball 28 of the foot and around the curved outer ends 46,
48 of the plate 44 and the first strap 26 has an eye 56 to which
the first line 40 is attached. The first strap 26 is also retained
by retainer 50.
[0031] The second strap 30 has sewn into a pocket thereof, not
shown, a second plate 58 having an elongate central portion and
curved outer ends 60, 62 spaced from one another a distance
sufficient for the central portion of the plate 58 to fit under the
toes 32 of the foot 16 and thereby provide rigidity for applying
pressure to the bottom of the toes 32. The plate 58 may be made
from metal, plastic, or any other rigid materials known to one
skilled in the art. The plate 58 may be sized and shaped and have
sufficient rigidity to reduce squeezing of the foot 16 when the
device 24 is pulled as described below. The second strap 30 has a
closed outer end 64 to thereby retain the second plate 58 below the
toes 32. The second strap 30 also has an eye 66 positioned opposite
the second plate 58 to which the second line 42 is attached.
[0032] The third strap 34 has first and second ends 68, 70 that
wrap around the ankle 38 and attach to one another by means of a
suitable connector such as hook and loop connectors, not shown. The
eye 36 is attached to the central portion of the third strap 34 and
is sized to slideably receive the second line 42.
[0033] The position of the third strap 34 with respect to the ankle
38 is maintained by means of a spacing strap 72 having a first end
74 adjustably attachable to the third strap 34 by means of a hook
and loop connector with one portion 78 attached to the spacer strap
72 and the second portion 80 attached to a tongue 79 connected to
the third strap 34. The second end 76 of the spacer strap 72 is
sufficiently long to fit within the open end of the second strap 30
and around the distal end of the toes 32 to thereby retain the
second end 74 with respect to the second strap 30.
[0034] In the preferred embodiment, the first and second lines 40,
42 are attachable to opposite ends of a single handle 82 and have
knots 84, 86 at their ends to prevent the removal of the lines 40,
42 from the handle 82. The lengths of the two lines 40, 42 are
adjustable by means of locking adjustments 88, 90 of the type known
in the art. Accordingly, the lines 40, 42 can be adjusted to the
lengths of the arms and the legs of the person making use of the
device 24.
[0035] To make use of the device 24, the second end 76 of the
spacer strap 72 is folded over and inserted into the open end of
the second strap 30 and secured over the ends of the person's toes
32 such that the second plate 58 is positioned under his or her
toes 32. The retainer 50, with the first plate 44 therein is
attached by means of the hook and loop connectors 52, 54 such that
the first plate 54 is positioned across the ball 28 of the foot.
Thereafter, the first strap 26 is positioned around the ball 28 of
the foot 16. The third strap 34 is positioned around the ankle 38
and retained in position by attaching the connectors 78, 80 to the
spacer strap 72. Finally, the user will adjust the length of the
lines 40, 42 such that he or she can apply pressure to the ball and
toes of his or her foot by pulling with one arm against the handle
82.
[0036] The user will use the strength of his or her arm to pull on
the handle 82 while the knee remains straight to apply pressure
against the first and second plates 44, 58. By pulling one end of
the handle 82, the user can apply pressure to the ball 28 of the
foot and thereby stretch the central portion of the plantar fascia
10 as shown in FIG. 5, or by pulling the other end of the handle
82, apply pressure below the toes of the foot 32, thereby
stretching the forward end of the plantar fascia 10 as shown in
FIG. 3. When both ends of handle 82 are pulled simultaneously,
pressure is applied to the toes 32 and the ball 28 of the foot,
thereby stretching the entire plantar fascia 10 at the same time.
The angle of force of line 42 created between the eye 66 of strap
30 and the eye 36 of strap 34 to the foot 16 is sufficiently small
to prevent strap 30 from releasing from the toes 32 and therefore
the user does not fear that the device will slide off of his or her
foot as he applies pressure to the toes and therefore the user does
not have to flex his toes against the force of the device to retain
the device on his or her foot as was the case with prior art
devices. The eye 36 attached to the third strap 34 draws the toes
towards the shin, thereby maximizing the pressure applied to the
toes 32 by drawing upon the second line 42 without pulling the
second strap 30 off the ends of the toes 32. Strap 26 is connected
to strap 30 by hook and loop fasteners that assist in anchoring
strap 30 on the toes during the exercising of the plantar
fascia.
[0037] As can be seen there has been disclosed a device 24 for
exercising the plantar fascia 10 of the foot 16, which will be
retained on the foot without requiring the user to flex muscles of
the foot that would interfere with the effectiveness of the
exercise. The device 24 also provides the ability to exercise
different portions of the plantar fascia 10. Furthermore, the
device can provide exercise to the Achilles tendon, the calf and
hamstring muscles, and the gluteus maximus without applying weight
to the leg and foot by increasing the pull on the handle 82.
[0038] To make use of the device 24, the second end 76 of the
spacer strap 72 is folded over and inserted into the open end of
the second strap 30 and secured over the ends of the person's toes
32 such that the second plate 58 is positioned under his or her
toes 32. The retainer 50, with the first plate 44 therein is
attached by means of the hook and loop connectors 52, 54 such that
the first plate 54 is positioned across the ball 28 of the foot.
Thereafter, the first strap 26 is positioned around the ball 28 of
the foot 16. The third strap 34 is positioned around the ankle 38
and retained in position by attaching the connectors 78, 80 to the
spacer strap 72. Finally, the user will adjust the length of the
lines 40, 42 such that he or she can apply pressure to the ball and
toes of his or her foot by pulling with one arm against the handle
82.
[0039] The user will use the strength of his or her arm to pull on
the handle 82 while the knee remains straight to apply pressure
against the first and second plates 44, 58. By pulling one end of
the handle 82, the user can apply pressure to the ball 28 of the
foot and thereby stretch the central portion of the plantar fascia
10 as shown in FIG. 5, or by pulling the other end of the handle
82, apply pressure below the toes of the foot 32, thereby
stretching the forward end of the plantar fascia 10 as shown in
FIG. 3. When both ends of handle 82 are pulled simultaneously,
pressure is applied to the toes 32 and the ball 28 of the foot,
thereby stretching the entire plantar fascia 10 at the same time.
The angle of force of line 42 created between the eye 66 of strap
30 and the eye 36 of strap 34 to the foot 16 is sufficiently small
to prevent strap 30 from releasing from the toes 32 and therefore
the user does not fear that the device will slide off of his or her
foot as he applies pressure to the toes and therefore the user does
not have to flex his toes against the force of the device to retain
the device on his or her foot as was the case with prior art
devices. The eye 36 attached to the third strap 34 draws the toes
towards the shin, thereby maximizing the pressure applied to the
toes 32 by drawing upon the second line 42 without pulling the
second strap 30 off the ends of the toes 32. Strap 26 is connected
to strap 30 by hook and loop fasteners that assist in anchoring
strap 30 on the toes during the exercising of the plantar
fascia.
[0040] As can be seen there has been disclosed a device 24 for
exercising the plantar fascia 10 of the foot 16, which will be
retained on the foot without requiring the user to flex muscles of
the foot that would interfere with the effectiveness of the
exercise. The device 24 also provides the ability to exercise
different portions of the plantar fascia 10. Furthermore, the
device can provide exercise to the Achilles tendon, the calf and
hamstring muscles, and the gluteus maximus without applying weight
to the leg and foot by increasing the pull on the handle 82.
[0041] Referring to FIGS. 7A and 7B, a device 124 is provided to
stretch the plantar fascia 10. The device 124 includes a first
strap 126 that is positionable under the ball 28 of the foot 16 and
a second strap 130 positionable under the toes 32 of the foot 16
similar to the embodiment shown in FIG. 1. A third strap 134 is
connectable to the patient above the foot 16, for example, around
the ankle 38 as shown in FIG. 7A. Alternatively, the third strap
134 may be connected to the patient just below the knee 17 as shown
in FIG. 9. A first line 140 may be attached to the first strap 126
and a second line 142 may be attached to the second strap 130. The
first, second, and third straps 126, 130, 134 may be made from any
material suitable for contacting a patient and are preferably made
of a durable, flexible, comfortable material such as canvas or
webbing.
[0042] The first strap 126 may include a first plate 144 to provide
a rigid surface under the ball 28 of the foot 16. The plate 144 may
be made from metal, plastic, or any other rigid materials known to
one skilled in the art. The plate 144 may be provided in the shape
of a rectangular bar and may include curved portions at the ends of
the plate 144 as described and shown above for the plate 44.
Alternatively, the plate 144 may be flat. In some embodiments, the
plate 144 may be sewn into the strap 126 or may be otherwise
operably connected to the strap 126. The first strap 126 may also
include a first connector 176 for connecting the first strap 126
with the first line 140. The first connector 176 may be any type of
connector. By way of non-limiting example, the first connector may
be an eye, a snap, a clip, a rivet and the like. As shown in FIG.
7A, the first line 140 may be threaded through the first connector
176, such as an eye, and then the first line 140 may be connected
to itself to secure the first line 140 with the first strap
126.
[0043] The second strap 130 may include a second plate 158 (not
shown) for placement under the toes 32 of the patient. Similar to
the plate 144, the plate 158 may be flat or curved and may be sewn
into the second strap 130 as shown in FIG. 7A. As described above,
the plate 158 may be used to provide a rigid surface and for
applying pressure to the bottom of the toes 32. The second strap
130 may also include a second connector 178 for connecting the
second strap 130 to the second line 142 as shown in FIG. 7A. The
second strap 130 may include a third connector 180 that may be
alternately connected to the second line 142 instead of the second
connector 178 or together with the second connector 178. The second
connector 178 and the third connector 180 are similar to the first
connector 176 described above.
[0044] In some embodiments, the first strap 126 may be connected to
the second strap 130 so that a base section 136 slides under the
foot 16. The straps 126, 130 may be pulled separately using lines
140, 142 respectively or the straps 126, 130 may be pulled together
using a single line 288 shown in FIG. 8. The base section 136 may
be formed from a single piece of material having top portions of
straps 126, 130 connected there to. Alternatively, the straps 126,
130 may be provided separately and connected together, i.e. by
sewing, riveting, or other wise connected the straps 126, 130
together, to form the base section 136. In some embodiments, the
straps 126, 130 may be provided separately.
[0045] The third strap 134 has first and second ends 168, 170 that
wrap around the patient, for example at the ankle 38, and attach to
one another by means of a suitable connector such as hook and loop
connectors, not shown. The third strap 134 may include a fourth
connector 184 to slideably receive the second line 142.
[0046] The first line 140 and the second line 142 may be connected
to a handle 182 as shown in FIG. 7B. The lines 140, 142 may be
adjustable, similar to the lines 40, 42 described above, or the
lines 140, 142 may be fixed in length. In some embodiments, a
single line may be threaded through the handle 182 and the first
line 140 extends to the first connector 176 and the second line 142
extends to the second connector 178 or the third connector 180.
[0047] An alternative embodiment of the device 224 having a single
line 288 connecting a first strap 226, a second strap 230 and a
third strap 234 to a handle 282 is shown in FIGS. 8-10. The device
224 may include similar features as the device 24, 124 described
above, for example a first plate 244 and a second plate 258 and the
like. The device 224 includes a first connector 276, a second
connector 278 and a third connector 284, similar to the connectors
described above, best seen in FIG. 10, showing the device 224
unattached to the patient. FIG. 10 also illustrates the single line
288 connecting the first, second and third straps 226, 230, 234. As
shown, the line 288 may be connected to the second connector 278 of
the second strap 230 and the line 288 connected to itself. The line
288 then connects through the third connector 284 in the third
strap 234 and subsequently through the first connector first
connector 276 of the first strap 226 and to the handle 282.
[0048] Similar to the device described above, the first strap 226
may be positioned under the ball 28 of the foot 16 and the second
strap 230 may be positioned under the toes 32. The third strap 234
may be positioned above the foot 16, for example, around the ankle
38 as shown in FIG. 8 or below the knee 17 as shown in FIG. 9.
[0049] For any of the devices described above, a first device may
be positioned on the left foot and a second device may be
positioned on the right foot and both the first and second devices
may be connected to a single handle such that both the left foot
and the right foot may be exercised simultaneously with the pull of
a single handle. An exemplary assembly is shown in FIG. 11, the
details of the individual devices may be found in the description
of the embodiments above. A first device 324 is connected to a
first foot 316 and a second device 424 is connected to a second
foot 416. The first device 324 may be connected above the first
foot 316 with an attachment member 334 and connected by at least
one first line 340 to a handle 382. The second device 424 may be
connected above the second foot 416 with an attachment member 434
and connected by at least one second line 440 to the handle 382.
The handle 382 may be any size and shape that can accommodate and
facilitate connecting and pulling on the lines 340 and 440.
[0050] In operation, the device 124, 224 is used to stretch the
plantar fascia as described above for the device 24 and the device
124, 224 may be provided for use with the lines threaded through
the device as described above. Briefly, the first strap 126, 226 is
positioned under the ball 28 of the foot 16 and the second strap
130, 230 is positioned beneath the toes 32. When the device
includes the base section 136, the straps 126, 226 are
simultaneously positioned on the foot 16. The third strap 134, 234
is positioned above the foot 16. When the lines 140, 142, 288 are
adjustable, the user may adjust the length such that the user may
apply pressure to the ball 28 and toes 32 by pulling with one arm
against the handle 182, 282, similar to the stretching described
above. Similar to the embodiment described above, the angle of
force of the line connected between the second strap under the toes
and the third strap positioned above the foot in the embodiments
described herein is sufficiently small to prevent the second strap
from releasing from the toes and therefore the user does not have
to flex the toes against the force of the device to retain the
device on the foot.
[0051] While the present invention has been described with respect
to preferred embodiments, it will be appreciated that many
modifications and variations may be made without departing from the
true spirit and scope of the invention. It is therefore the intent
of the appended claims to cover all such modifications and
variations which fall within the spirit and scope of the
invention.
