Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should also be understood that although the elongated member 26 is attached to the shoe 28 via fasteners 38a, 38b, the elongated member 26 may be attached to the shoe 28 or foot of the user via attachment mechanisms or any other suitable means. For example, a locking plate (not shown) may be attached to the elongated member 26 among the plurality of positions. The shoe 28 may be secured to the locking plate via straps (not shown), for example, such that the shoe 28 is attached to the elongated member 26. A foot of the user 12 may be inserted into the shoe 28 (via an opening 50), thereby securing the foot of the user 12 to the shoe 28. The foot of the user 12 may also be attached directly to the elongated member 26 (i.e., without the shoe 28) via the locking plate or any other attachment mechanisms (e.g., straps).
As shown in
The vibration members 64 may be connected to the motor 62 such that a gap exists between ends of the vibration members 64 and the top surface 59 of the elongated member 26 when the motor 62 is in an OFF mode. The vibration members 64 are configured to move up and down when the motor 62 is turned to an ON mode. This causes the vibration members 64 to impact the top surface 59 of the elongated member 26 such that the elongated member 26 oscillates back and forth (
As shown in
The memory unit 70 may store template images therein. The template images may be medical images (e.g., ultrasound images, magnetic resonance imaging (MRI), etc.) of muscles, for example, in predetermined conditions (e.g., mild muscle strain, severe muscle contusion). Each template image may be associated with a treatment protocol. For example, a template image of a lower leg muscle that has a mild strain may be associated with one treatment protocol. In another example, a template image of a lower adnominal muscle that has a mild strain may be associated with another treatment protocol.
The processor 68 may communicate with the memory unit 70 to match the uploaded image to a corresponding template image stored in the memory unit 70. Once the uploaded image is matched to the corresponding template image, the treatment protocol associated with the template image is obtained. Based on the treatment protocol, the computing device 22 may notify the user 12 of the shoe 28 to put on (i.e., left shoe or right shoe) and a position in which the elongated member 26 should be attached to the shoe 28 that the user 12 has on. Once the user 12 puts on the shoe 28 and attaches the elongated member 26 to the shoe 28 that the user 12 has on, the user 12 may select a control on the computing device 22 to start the treatment protocol, which, in turn, transmits a signal to the motor 62 to turn the motor 62 to the ON mode. Based on the treatment protocol, the signal transmitted to the motor 62 causes the motor 62 to turn ON for a predetermined duration and at a predetermined power. It should be understood that, in some configurations, based on the treatment protocol, the signal transmitted to the motor 62 causes the power of the motor 62 to vary over the course of the predetermined duration. For example, if the motor 62 is to run for a predetermined duration of 10 minutes, the motor 62 may operate at a first power for 5 minutes and a second power for 5 minutes.
It should be understood that, in some configurations, the memory unit 70 may be remote (e.g., in a cloud baser server) and may store template images therein. In such configurations, the computing device 22 may communicate with the remote memory unit 70 such that the uploaded image may be matched to a corresponding template image stored in the memory unit 70 and the treatment protocol associated with the corresponding template image is obtained.
It should also be understood that in the event that the uploaded image does not match any of the template images stored in the memory unit 70, a custom treatment protocol will be created for that uploaded image based on the template images stored in the memory unit 70. For example, if the uploaded image is close to two template images that are stored in the memory unit 70, the custom treatment protocol may be a combination of the treatment protocols that are associated with the two template images.
In some configurations, as shown in
With reference to
At 212, the control algorithm, using the processor 68, matches the uploaded image to a corresponding template image that is stored in the memory unit 70 of the computing device 22 and obtains the treatment protocol associated with the corresponding template image. At 216, the control algorithm, using the processor 68, generates a notification indicating which position of the plurality of positions to attach the flexible elongated member 26 to the shoe 28. For example, the elongated member 26 may be attached to the shoe 28 in a first position in which the elongated member 26 and the shoe 28 are parallel to each other (i.e., the shoe 28 extends in a direction parallel to a longitudinal axis of the elongated member 26). In another example, the elongated member 26 may be attached to the shoe 28 in a second position in which the elongated member 26 is angled (i.e., non-parallel angle) relative to the shoe 28 (i.e., the portion of the elongated member 26 extends past the inward portion 34 of the shoe 28 at the front end thereof and the other portion of the elongated member 26 extends past the outward portion 36 of the shoe 28 at the rear end thereof).
At 220, the control algorithm, using the processor 68, notifies the user 12 to start the treatment protocol. Once the user 12 starts the treatment protocol, the computing device 22 transmits a signal to the motor 62 to turn the motor 62 to the ON mode. Based on the treatment protocol, the signal transmitted to the motor 62 causes the motor 62 to turn ON for a predetermined duration and at a predetermined power. In some configurations, based on the treatment protocol, the signal transmitted to the motor 62 causes the power of the motor 62 to vary over the course of the predetermined duration. For example, if the motor 62 is to be turned to the ON mode for a predetermined duration of 10 minutes, the motor 62 may operate at a first power for 5 minutes and a second power for 5 minutes. The motor 62, when in the ON mode, moves the vibration members 64 up and down, which causes the elongated member 26 to oscillate (
The teachings of the present disclosure provides the benefit of allowing the user 12 to exercise and/or rehab his or her lower body portion 13 without movement of his or her lower body portion 13. It should be understood that, in some configurations, the user 12 may manually move his or her legs up and down, for example, to cause oscillations of the elongated members 26, thereby exercising and/or rehabbing his or her lower body portion 13. The teachings of the present disclosure may also allow the user 12 to exercise and/or rehab at home as oppose to exercising and/or rehabbing at a gym or rehabilitation facility. The teachings of the present disclosure may also allow the user 12 to exercise and/or rehab different areas of his or her lower body portion 13 based on the treatment protocol (i.e., based on the position that the elongated member 26 is attached to the shoe 28 and based on the duration that the motor 62 is turned ON for and the power that the motor 62 is set at).

Each of the attachment clamping mechanisms 102, 104, 106, 108 may include a corresponding actuator 102a, 104a, 106a, 108a that operates to close the corresponding attachment clamping mechanisms 102, 104, 106, 108 and secure the shoe 28 to the elongated member 26. For example, the actuators 102a, 104a, 106a, 108a can include a spring loaded actuation device with a lock and release mechanism. In such case, the attachment clamping mechanisms 102, 104, 106, 108 can be manually rotated to an open and locked position. The actuators 102a, 104a, 106a, 108a can be connected to an actuator trigger 112 (shown in
Additionally or alternatively, the actuators 102a, 104a, 106a, 108a can be electrically operated actuators with one or more electrical motors, such as one or more stepper motors, that drive the pivotable portions of the attachment clamping mechanisms 102, 104, 106, 108 between the open and closed positions. In such case, the actuator trigger 112 can be a sensor, such as a proximity sensor, that senses when a shoe 28 is placed within the shoe binding apparatus 100 and communicates an actuation signal to the actuators 102a, 104a, 106a, 108a triggering the actuators 102a, 104a, 106a, 108a to drive the pivotable portions of the attachment clamping mechanisms 102, 104, 106, 108 to the closed position, securing the shoe 28 to the elongated member 26. Additionally or alternatively, the actuator trigger 112 can be a button that is depressed by the user 12 with the shoe 28. The actuator trigger 112 can be electrically connected to and in communication with each of the actuators 102a, 104a, 106a, 108a and can communicate the actuation signal to the actuators 102a, 104a, 106a, 108a. For example, in an embodiment where the actuator trigger 112 includes a proximity sensor, the actuator trigger can communicate the actuation signal to the actuators 102a, 104a, 106a, 108a when the proximity sensor senses that a shoe has entered the shoe binding apparatus 100. For further example, in an embodiment where the actuator trigger 112 includes a button, the actuator trigger 112 can communicate the actuation signal to the actuators 102a, 104a, 106a, 108a when the proximity sensor senses that a shoe has entered the shoe binding apparatus 100. Additionally, the release button 110 (shown in

Additionally, the poles 130 can each be configured with a motor assembly, similar to motor 62, and with vibration members, similar to vibration members 64, that cause the poles 130 to oscillate. For example, the motor and vibration members may be positioned within the interior of the poles 130, causing the poles to oscillate when operated. In this way, the oscillations of the poles 130 can provide exercise to the arms of the user 12, while the oscillations of the elongated members 26 can provide exercise to the legs of the user. In addition, the rotational motion of the rotational drums 140 can provide additional exercise to the legs of the user 12 due to the rotational cycling motion of the shoes of the user 12 while attached to the elongated members 26, which are in turn attached to the rotational drums 140. In addition, the rotational motion of the rotational drums 140 can provide additional exercise to the arms of the user 12 due to the back and forth motion of the arms of the user 12 as the user holds on to the poles 130 attached to the rotational drums 140.
