Description

CA 02317156 2000-08-30
This invention relates to a physiotherapy bench.
People suffering from back pain and in particular lower back pain, sometimes
require physiotherapy treatment. Such treatment is usually carried out while
the
patient lies in a prone position on a horizontal physiotherapy bench having a
flat
supporting panel. It has been found that a flat surface causes the spine
joints in the
lower back to undergo compression when the patient is in the prone position.
Compression of the spine can increase a patient's discomfort and make
treatment
difficult. Back pain is best treated when the spine is in an uncompressed or
"neutral"
position.
Similarly, the placing of the patient's neck joints in a neutral position
during
treatment is desirable. A flat support surface also causes the neck to be
compressed when the patient is in the prone position on the physiotherapy
bench.
Even when the bench includes a separate headrest, the headrest must be
properly
adjusted to avoid compression of the patient's neck.
Physiotherapy support panels are usually horizontal and elevated above the
floor. Many patients have difficulty getting onto a raised horizontal bench
and
positioning themselves in the prone position thereon without twisting their
spine.
This is a serious problem, because such twisting can cause additional back
pain.
Many conventional physiotherapy benches do not have sufficient leg room
below the support panel to permit a physiotherapist to work close to the
patient.
This results in the physiotherapist having to reach to treat the patient. The
more a
physiotherapist must reach during treatment, the greater the risk of the
physiotherapist suffering back injury:

Physiotherapy benches are not usually available for home treatment, and it is
necessary to improvise, using a flat surface such as a bed or table. An
improvised
bench of this nature has the disadvantage that the patient will not likely be
supported
at a height convenient and comfortable to the physiotherapist. This can result
in the
physiotherapist developing a backache during prolonged treatment.
The object of the present invention is to provide a physiotherapy bench, which
solves the problems involved with conventional physiotherapy benches discussed
above, supports a patient's neck and spine in the neutral position, and is
adjustable
and portable to suit the requirements of both patient and physiotherapist.
Accordingly, the invention relates to a physiotherapy bench comprising a
frame; legs for supporting said frame in an elevated use position; an arcuate
supporting panel; legs for supporting said panel and frame in a use position
in which
said supporting panel includes a substantially horizontal front end for
supporting the
chest of a patient and an inclined rear end for supporting the hips and the
upper
portion of the legs of a patient; and a headrest separate from said panel
connected
to said frame at said front end for supporting the head of a patient.
The invention is described below in greater detail with reference to the
accompanying drawings, which illustrate a preferred embodiment of the
invention,
and wherein:

Figure 11 is a bottom view of the bench of Fig. 1 in the collapsed condition.
Referring to the drawings, the basic elements of the physiotherapy bench in
accordance with the present invention include a skeletal frame generally
indicated at
1, a panel 2 mounted on the frame 1 for supporting the body of a patient, rear
legs 3
and front legs 4 for supporting the frame 1 in an elevated position, and a
headrest 5
for supporting the head of a patient.
As best shown in Fig. 2, the support frame 1 is defined by a pair of tubular
sides 6 interconnected by crossbars 7, 8, 9,10 and 11. The sides of the frame
include straight, parallel rear sections 14, forwardly converging middle
sections 15,
and straight parallel front sections 16. Short arms 18 extend outwardly from
the
front ends of the middle sections 15 for supporting the sides of the panel 2.

The frame 1 carries the panel 2 which is defined by a laminated plywood base
20 (Fig. 5), a foam pad 21 on the base 20 and a plastic, fabric or leather
cover 22
extending around the top, sides and ends of the panel. A strip 23 (Fig. 2) of
carpet
material covers the bottom of the panel 2. The front and rear ends of the
panel 2
are straight, and the sides taper from the rear to the front end thereof. A
narrow
front section 24 of the panel 2 is intended to support the chest of a patient,
while a
wider rear portion 25 is intended to support the hips and top ends of the legs
of the
patient. The use of laminated plywood to form the base 20 of the panel 2
permits
bending of the panel during production whereby the finished panel is arcuate,
the
front end being substantially horizontal in the use position and the rear end
being
inclined. The angle between the planes of the front and rear portions 24 and
25 is
16 . Referring to Figs. 2 and 4, it will be noted that the sides 6 of the
frame 4 are
substantially coextensive with the panel 2 and are bent in the same manner as
the
panel 2 for supporting the panel along the entire length thereof.
The frame 1 and consequently the panel 2 are supported in an elevated use
position by the rear and front legs 3 and 4, respectively. The rear legs 3 are
generally chevron-shaped, one arm 27 thereof being parallel to the rear end of
the
side 6 of the frame 1 in the erect position. The free end of each arm 27 is
pivotally
connected to one frame side 6 by a pin 28 (Fig. 2) extending inwardly from
such free
end. A crossbar 29 interconnects the legs 3 at their elbows 30. The legs 3 are
telescopic. For such purpose, a foot 31 is slidably mounted in the bottom free
end of
each leg 3. The foot is retained in one of a plurality of positions by a
generally U-
shaped spring clip, and buttons (not shown) on the ends of the clip for
engaging
4

CA 02317156 2000-08-30
holes 33 in the legs 3. Plastic glides 35 are provided on the bottom free ends
of the
legs 3.
Each of the front legs 4 is also pivotally connected to the frame sides 6 by
arms 36 (Fig. 2) extending inwardly from the top free ends of the legs 4. The
legs 4
include steps 37 for supporting arm rests 38. The arm rests 38 are similar in
structure to the panel 2 including a solid base 40, a foam pad (not shown) and
a
cover 41. Arms 43 extending outwardly from the steps 37 provide additional
support
for the arm rests 38. Crossbars 44 and 45 extend between the legs 4 beneath
the
steps 37 and at the top of the legs, respectively for maintaining the legs
spaced
apart the appropriate distance, and for causing the legs 4 to move together
from a
folded (Fig. 6) to an extended or erect position (Figs. 3 and 4).
Like the rear legs 3, the front legs 4 are also telescopic, including feet 46
extending downwardly from the bottom ends thereof. The feet 46 of front legs 4
can
be latched in one position in the same manner as the rear legs 3.
Referring to Figs. 6 to 9, the headrest 5 for supporting a patient's head is
connected to the front end of the frame 1 by an elongated leaf spring 50, so
that the
patient's head literally floats with the headrest during physiotherapy. The
headrest 5
includes a padded, generally U-shaped body 51 with a concave front end 52 for
supporting the forehead of a patient. Arcuate arms 53 extend upwardly and
rearwardly frm the front end for supporting the cheeks of the patient's head.
A
generally keyhole-shaped opening 54 (Fig. 7)in the bottom of the headrest 5
receives the nose and mouth of the patient, so that breathing is not
restricted.
5

CA 02317156 2000-08-30
The leaf spring 50 is an elongated strip of steel with a concave outer front
end
56, which is connected to the body 51 by a bracket 57. The bracket 57 is
connected
to the body 51 by bolts 58, and the outer end of the spring 56 carries a pin
60
extending through the arms of an inverted U-shaped outer end of the bracket
57. A
bolt 60 extending through the spring 50 engages the bottom of the body 51. By
manually rotating the bolt 62 using a knob 63 on the bottom free end thereof,
the
body 51 is rotated around the longitudinal axis of the pin 60 to change the
inclination
of the headrest 5 with respect to the panel 2 and the spring 56.
The inner or rear end 65 of the spring 50 is slightly arcuate, and is
connected
to the frame 1 beneath the panel 2. The spring 50 extends through a pair of
generally U-shaped brackets 66 and 67 (Fig. 2) which are connected to the
bottoms
of the crossbars 9 and 10, respectively. By tightening a bolt (not shown) in
the rear
bracket 66 using a knob 68, the spring is locked in one position, i.e. is
prevented
from moving longitudinally in the bracket 66 relative to the frame 1. As shown
in Fig.
10, the bracket 67 is high enough that the spring 50 can move vertically
therein.
The spring 50 extends through a swivel head 70 on the top end of a bolt 72 in
the
bracket 67. By manually adjusting the bolt 72 using a knob 73, the height of
the spring 50 and consequently the headrest 5 are changed. Thus, the height of
the
headrest 5 and the spacing of the headrest from the front end of the panel 2
can
readily be adjusted.
Referring to Figs. 10 and 11, when the bench is not in use, i.e. in the
storage
or transport condition, the spring 50 is removed from the brackets 66 and 67,
and
the headrest 5 is reversed and stored under the panel 2. In such condition,
the
6

CA 02317156 2000-08-30
spring 50 is retained by a Velcro (trade-mark) strip 75 (Fig. 2) on the
crossbar 10,
and extends through the bracket 66 into the bracket 67. The knob 68 is rotated
to
clamp the spring 50 in the storage position. The rear legs 3 are folded
forwardly,
and the front legs 4 are folded rearwardly into overlapping relationship with
the rear
legs 3 to form a compact assembly.
In the erect, use position of the bench, the front and rear legs 3 and 4 are
slightly inclined. The length of the legs and the position of the headrest 5
are
adjusted to suit the patient. The inclined rear portion 25 of the panel 2
permits the
patient to crawl onto the bench. With a patient prone on the bench, the head
of the
patient is above his or her feet. The arcuate shape of the top of the panel 2
causes
stretching of the spine, facilitating physiotherapy on the patient's back. The
curved
top of the bench causes a natural, gentle traction. A heavy patient will cause
the
legs 3 and 4 to flex slightly. The taller the patient, the more his or her
legs dangle
over the rear end of the panel 5 and the greater the traction. As mentioned
above,
the elongated leaf spring 50 supporting the headrest 5 in spaced apart
relationship
to the panel 2, gives the patient the impression that his or her head is
floating, while
the body is fully supported by the panel 2. When the position of the headrest
5 is
correctly adjusted, the patient's neck is in gentle traction. With a
conventional
bench, the neck is in compression.
Because the bench 2 is narrower in the area of the patient's spine, and the
legs 3 and 4 are inclined outwardly from the frame 1, a therapist can get
closer to
the patient than with existing benches. This prevents therapist back strain,
provides
a relatively comfortable working position and improves technique.
