Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to US Provisional
Application No. 62/393,348 filed Sep. 12, 2016, entitled ADJUSTABLE
REHABILITATION AND EXERCISE DEVICE, incorporated herein by
reference in its entirety.
FIELD
[0002] This disclosure relates to the field of rehabilitation
devices. More particularly, this disclosure relates to
rehabilitation devices capable of providing continuous passive
motion for improved rehabilitation options.
BACKGROUND
[0003] Improvement is desired in the construction of rehabilitation
and exercise devices. Conventionally, rehabilitation and exercise
devices are either powered solely by the patient by muscle force of
the patient, or are solely powered by a powered motive force such
as supplied by an electric motor for provision of continuous
passive motion ("CPM").
[0004] The powered devices simply rotate pedals to which the feet
of the patient are secured and the patient is a passive participant
or are a CPM device of known construction and configuration. The
powered devices serve to move the feet/legs of the patient through
a range of motion, but do not permit or require any application of
muscle force by the patient. These devices are typically utilized
in early stages of rehabilitation just to impart motion to the legs
or as CPM treatment is otherwise indicated by the patient's
condition, diagnosis or treatment/rehabilitation plan. Once the
patient is better able to exert muscle force, a conventional muscle
powered device with variable resistance is utilized. Alternatively,
a home medical company, durable medical equipment company or mobile
rehabilitation company may have the need to treat multiple patients
requiring different treatment or rehabilitation protocols. In some
instances, certain patients may have been prescribed CPM protocols
while other patients have been prescribed patient muscle powered
treatment protocols and it would be useful to be able to provide
both types of protocols with a single device.
[0005] Presently, no known device exists that provides continuous
passive motion, powered or powered movement assistance and yet
enables participation by the patient in application of muscle force
in a manner in which the motor used in the CPM or powered mode is
selectively engageable. Such a device is desired and provided by
the present disclosure.
SUMMARY
[0006] The disclosure provides a rehabilitation and exercise device
that provides continuous passive motion, powered or powered
movement assistance and yet enables participation by the patient in
application of muscle force in a manner in which the motor used in
the CPM or powered mode is selectively engageable.
[0007] In one aspect, the device includes a rotary member mounted
for rotary motion and having a patient engagement member
operatively associated therewith; a motor having a force output;
and a clutch having a linkage connecting the motor to the rotary
member.
[0008] The motor and the clutch are operable to:(1) apply the force
output of the motor to rotate the rotary member at a first motor
rotational rate without application of any muscle force by a
patient, (2) not apply the force output of the motor to the rotary
member so that muscle force must be applied by the patient to
rotate the rotary member at a first patient rotational rate, or (3)
apply the force output of the motor to the rotary member in a
varying amount, to provide the output force of the motor in amount
to provide a second motor rotational rate to provide continuous
passive rotational motion of the rotary member, yet enable desired
participation by the patient to apply muscle force to rotate the
rotary member, wherein when the patient applies muscle force, the
motor and the clutch may be operated to (a) maintain the rate of
rotation the rotary member the same as when the patient is not
applying muscle force, with the amount the force output of the
motor being decreased in an amount corresponding to the amount of
muscle force applied by the patient, or enable the rate of rotation
of the rotary member to increase corresponding to the amount of
muscle force applied by the patient.
[0009] In another aspect, the motor and clutch are operable to (1)
apply rotational force from the motor to the rotary member without
requiring use of muscle power of a patient; (2) disengage the motor
is completely from the rotary member so that the rotary member is
capable of free motion; or (3) apply rotational resistance from the
motor to the rotary member to resist muscle powered rotation of the
rotary member with a selectable amount of resistance.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Further advantages of the disclosure are apparent by
reference to the detailed description when considered in
conjunction with the figures, which are not to scale so as to more
clearly show the details, wherein like reference numbers indicate
like elements throughout the several views, and wherein:
[0011] FIGS. 1A-1D show rehabilitation and exercise devices
according to the disclosure that provide continuous passive motion
and enables powered movement, yet enable participation by the
patient in application of muscle force.
DETAILED DESCRIPTION
[0012] With initial reference to FIG. 1A, there is shown
rehabilitation and exercise device 10 configured to provide
continuous passive motion and enable powered movement, yet enable
participation by a patient in application of muscle force. The term
patient is broadly used to refer to any user of the device. The
device 10 is particularly configured to rehabilitate a patient
post-surgery or accident or injury.
[0013] The device 10 is described herein configured as a bicycle
structure for exercising the legs of a patient. The device 10 may
be configured for interacting with a patient to be rehabilitated
for various conditions, and may be configured for use with lower
body extremities such as the feet, legs, or upper body extremities
such as the hands, arms, and the like. For example, the embodiments
of FIGS. 1A and 1B are configured for engagement by the legs of the
patient, whereas the embodiments of FIGS. 1C and 1D are configured
for engagement by the hands of the patient.
[0014] The rehabilitation and exercise device 10 of FIG. 1A may
take the form as depicted of a traditional exercise/rehabilitation
device which is more or less non-portable and remains in a fixed
location, such as a rehabilitation clinic or medical practice.
[0015] Alternatively, the device 10 may be configured to be smaller
and more portable unit so that it is able to be easily transported
to different locations at which rehabilitation or treatment is to
be provided, such as a plurality of patient's homes, alternative
care facilities, at a patient's bed, or the like. This is seen, for
example, in the embodiments of FIGS. 1C and 1D. Along these lines,
it will be appreciated that devices according to the disclosure may
be equipped with adaptive structure to enable location of the
devices on or adjacent a bed, wheelchair, or the like of a
patient.
[0016] Returning to FIG. 1A, the device 10 includes an electric
motor 12, yet enables participation by the patient in application
of muscle force. The device 10 includes a rotary device such as a
wheel 14 or flywheel or the like rotatably mounted such as by a hub
located at the center of the wheel 14 to a frame 16 or other
support. It will be appreciated that the wheel 14 will include
patient engagement members, such as a pedal 14a. Preferably, one of
the wheels 14 with a pedal is mounted on either side of the frame
16.
[0017] The pedal 14a is desirably adjustably positionable on the
wheel 14. As shown, the wheel 14 includes a plurality of spaced
apart and elongated slots 14b, with a mount adjustably connecting
the pedal 14a to one of the slots so that the pedal location is
radially adjustable to hub or the center where the wheel is
mounted. Thus, the ability to select amongst the slots 14b and the
radial location along the slot 14b for the pedals 14a on the wheels
14 on either side of the device 10, a user may adjust the location
of the pedals 14a relative to the hub and angularly with respect to
one another. Thus, a therapist or the like may adjust the locations
of the pedals for a desired therapeutic effect.
[0018] The motor 12 is connected to the wheel 14 as by a clutch 18,
such as a slip differential clutch. The clutch 18 may be
electronically or manually linked to the motor 12 as by a linkage
20. The motor 12 is configured to desirably rotate the wheel 14 so
that the device 10 may serve to move the feet/legs of the patient
through a range of motion, but do not require any application of
muscle force by the patient. If desired, the clutch 18 may be
operated to disconnect the motor 12 from the wheel 14 so that the
only force applied to the wheel 14 will be the muscle force of the
patient.
[0019] The clutch 18 is also advantageously operable to provide
continuous passive motion and enable powered movement of a desired
and adjustable amount provided by the motor 12, yet enable desired
participation by the patient in application of muscle force. When
the clutch 18 is disengaged it is desirable for adjustable
resistance to be applied to resist the muscle powered rotation of
the patient engagement members in a conventional fashion to
facilitate the smooth rotation of the patient engagement members
and/or to facilitate exercise of the patient's extremities.
[0020] The motor and the clutch are operable to:(1) apply the force
output of the motor to rotate the rotary member at a first motor
rotational rate without application of any muscle force by a
patient, (2) not apply the force output of the motor to the rotary
member so that muscle force must be applied by the patient to
rotate the rotary member at a first patient rotational rate, or (3)
apply the force output of the motor to the rotary member in a
varying amount, to provide the output force of the motor in amount
to provide a second motor rotational rate to provide continuous
passive rotational motion of the rotary member, yet enable desired
participation by the patient to apply muscle force to rotate the
rotary member.
[0021] When the patient applies muscle force, the motor and the
clutch may be operated to (a) maintain the rate of rotation the
rotary member the same as when the patient is not applying muscle
force, with the amount the force output of the motor being
decreased in an amount corresponding to the amount of muscle force
applied by the patient, or enable the rate of rotation of the
rotary member to increase corresponding to the amount of muscle
force applied by the patient.
[0022] In addition, the device 10 may be operated to apply
rotational force from the motor to the rotary member when in a
patient selected continuous passive motion (CPM) mode without
requiring use of muscle power; freewheel when in a patient selected
freewheel mode so that the motor is completely disengaged from the
rotary member; or apply rotational resistance from the motor to the
wheel when in a patient selected exercise mode to resist muscle
powered rotation of the wheel with the amount of resistance being
selectable by the patient, such that the motor functions in the
nature of a generator.
[0023] Accordingly, it will be appreciated that devices according
to the disclosure are configured to provide continuous passive
motion, powered or powered movement assistance, yet enable
participation by the patient in application of muscle force in a
manner in which the motor used in the CPM or powered mode is
selectively engageable.
[0024] With reference now to FIG. 1B, there is shown a variation of
the device 10, which further includes a computer processor 22 in
electrical communication with both the motor and a plurality of
patient sensors 24. The computer processor 22 is able to wirelessly
receive signals from the sensors 24, and is programmable to enable
desired actions to be taken in response to the signals received
from the sensors 24. For example, one of the sensors 24 is shown on
the knee of the patient. This sensor may be a range of motion
sensor. Another sensor is shown on the chest area. This may be a
heart rate sensor. Another sensor is shown on the foot of the user.
This may be a blood flow or oxygen sensor. As will be appreciated,
a number of different sensors may be utilized. The computer
processor 22 may be programmed to sound alarms, increase or
decrease the force output of the motor, and the like based on the
combination of inputs from the sensors. It will be further
appreciated that data associated with the output of the sensors 24
may be stored and utilized in monitoring the patient and collecting
data about the patient and the exercise and rehabilitation of the
patient.
[0025] For example, data such as pedal revolutions, time of use,
pedaling speed, and any other data from other sensors may be
tracked via the computer processor and transmitted wirelessly to a
data server from which they are uploaded to the patient's medical
records. The data can also be pushed to the patient's smartphone
where a mobile application tracks and displays the patient's
activity, including a graph of usage and progress over time.
[0026] These data collection features offer three significant
advantages over current CPM units. For example, a physician and/or
physical therapist can monitor their patient's use remotely,
ensuring the patient is using the device for the duration and
frequency directed. The physician or therapist can also be notified
in the event a patient is failing to use the device, and contact
the patient to follow up via a billable telemedicine video or phone
call.
[0027] Also, this device enables for the first time, detailed data
regarding post-operative therapeutic exercise at home can be
collected by both healthcare providers and payors, and correlated
with patient outcomes, speed of recovery, and reduction of
complications and re-admissions. These features also present a
significant value to insurers, to whom specific patient data is
particularly valuable.
[0028] The sensors 24 may also be configured to be electrodes for
electrical muscle stimulation to push electrical current into the
muscle tissue below, resulting in a sensory or motor response. For
this use, wires may be connected to each electrode to supply
electrical current from a controllable source of electrical power.
Alternatively, as represented by the dashed lines, a wireless
connection may be made to each electrode, with a source of
electrical power controlled by the computer processor. Electrical
stimulation supplied by the electrodes are utilized for pain relief
and muscle re-education, in which the electrical current helps the
atrophied muscle(s) contract. Along with increasing muscle
function, the contraction of the muscle promotes blood flow to the
area that assists in healing.
[0029] With reference to FIG. 1C, there is shown a device
configured in the manner of the device 10, except of reduced weight
and dimension and configured for placement on a table or bed or the
like. As shown, the device is configured to exercise the upper body
of the patient.
[0030] With reference to FIG. 1D, there is shown a device
configured in the manner of the device 10, except it is adapted to
be mountable adjacent a hospital bed or the like. For example, in
this case, the device is adjustably mounted on mount, such as a
ceiling track, and may be raised or lowered or moved laterally or
longitudinally or otherwise adjusted in position relative to the
patient, as depicted by the double-ended arrows. As will be
appreciated, this enables the device to be conveniently adjusted in
position to the patient, and moved away from the bed or other
location when not in use. It will be appreciated that instead of
locating the device on a ceiling track, a track or the like may be
mounted on the bed or other desired location.
[0031] The foregoing description of preferred embodiments for this
disclosure has been presented for purposes of illustration and
description. It is not intended to be exhaustive or to limit the
disclosure to the precise form disclosed. Obvious modifications or
variations are possible in light of the above teachings. The
embodiments are chosen and described in an effort to provide the
best illustrations of the principles of the disclosure and its
practical application, and to thereby enable one of ordinary skill
in the art to utilize the disclosure in various embodiments and
with various modifications as are suited to the particular use
contemplated. All such modifications and variations are within the
scope of the disclosure
