Description

BACKGROUND
• The present invention relates to a system and method for facilitating proper exercise techniques and more particularly to a sensor based feedback system and method for facilitating pelvic and spine exercise techniques to strengthen core muscles, namely the lumbar intrinsic musculature and abdominal muscles.
• Lower back pain is a chronic medical problem in today's society, and the yearly cost can reach as high as $600 billion per year. The economic impact of lower back pain can be subdivided into direct and indirect costs; indirect costs primarily relate to employment and household productivity, while the direct costs involve physician services, medical devices, medications, hospital services, and diagnostic testing. An estimated 8 out of 10 Americans suffer from back pain at some point in their lives. Back pain lasting longer than two weeks occurs in 16% of the population between the ages of 24 and 75, as reported by The National Health and Nutrition Examination Survey II. The ramifications of this pain contribute to 149 million lost workdays in the United States annually, with an estimated cost of $1,230 per male worker and $773 per female worker. The net effect of these lost workdays translates to a loss of approximately $28 billion per year in the United States, and £1.6 billion in the United Kingdom.
• Presently, many solutions exist to purportedly reduce lower back pain, including both established medical therapies and alternative therapeutic treatments. Standard medical treatments for acute low back pain include analgesic and anti-inflammatory treatments, such as ibuprofen or aspirin, heat and cold therapy, and various back exercises and stretches to relieve the stress on the lower back. Chronic lower back pain is more heavily contended, with a wide range of available solutions.
• Physical therapy and chiropractic approaches utilize a broad range of exercises to strengthen portions of the lower back and additionally to increase flexibility. The currently espoused belief is that these exercises would decrease the deleterious effects of lower back pain. In all of the aforementioned approaches, the muscles strengthened and stretched are user-specific and dependent upon the nature of the injury, including cause, symptoms, and pain location. Surgery can only be applied to specific situations and is generally reserved for the most severe cases, such as osteomyelitis, spinal fractures, nerve compressions, stenosis, severe disc degeneration, and disc herniations. In addition to general approaches, specific devices have been developed to facilitate lower back exercises.
BRIEF SUMMARY

DETAILED DESCRIPTIONOverview
• The present invention provides a sensor based feedback system and method for addressing lower back pain by isolating and strengthening core musculature, including “intrinsic” muscles in the lower back, such as the lumbar multifidi. The invention is based on the theory that lower back pain is often the result of dysfunctional lumbar multifidi, which in turn causes the user to compensate by using other “extrinsic” muscle groups. That is, dysfunction of the intrinsic musculature, which normally stabilizes the lumbar spine, forces the prime movers or locomotive muscles to become reflexively hypertonic to compensate. The most commonly noted compensatory musculature in lumbo-pelvic derangement includes the hamstring, piriformis, erector spinae, psoas, and quadratus lumborum. Damage or misuse of the multifidi leads to compensation by the muscles previously mentioned, and may cause abnormal motion (or alignment) of the spine. Abnormal motion or alignment of the spine has been shown to be a cause of chronic lower back pain. Lumbar exercises have been shown to be effective for treating chronic low back pain. Note that for the purposes of this disclosure, the term core muscles may refer to, e.g., spinal, abdominal, and pelvic muscles.
• In accordance with an embodiment of the invention, there are three primary exercises (referred to herein as core, pelvic or lumbar multifidi exercises) that are used to strengthen the core and alleviate lower back pain.
• I. The anterior/posterior pelvic tilt involves front-to-back movement of the lumbar spine and pelvis.
• II. The side-to-side pelvic tilt is similar, but uses a lateral sway.
• III. The “pelvic circles” exercise describes a clockwise and counterclockwise circular movement of the pelvis.
• For those with compromised intrinsic muscles, these core exercises initially can be difficult to perform properly and often there is compensation by other muscles, reducing the effectiveness of the exercises. Compensation by incorrect muscles is verified by cues such as raising the shoulders unilaterally or bilaterally, flexion or extension of the torso, and/or movement of the lower extremities, e.g., lifting the heels or pushing down with the feet while seated on an unstable surface or seat (such as a large ball or cushion).
• The present invention utilizes a sensor based feedback system to assist users, e.g., with visual and audio clues, to properly perform above noted core exercises. Without such feedback, users would typically have a hard time isolating the correct muscles to move. With time however, the final result is the correction of the poor motor patterns and amelioration of the lower back pain with the user having the ability to discern proper lumbo-pelvic movements from improper movement. Ultimately, the user is empowered to erase or decrease fear avoidance behavior and regain confidence in their lower back movements.
Illustrative Embodiments
• Referring now to the drawings,FIG. 1 depicts an illustrative sensor-basedcore exercise system11 for providing sensor based feedback and guidance to auser40 performing any one of the three core exercises noted above. This embodiment utilizes three systems ofsensors34,36, and38, to collect data from theuser40 that is analyzed bycomputer system10 to ensure that the exercises are being done correctly. For the purposes of this disclosure, the term sensor or sensor system refers to any device or mechanism that can detect an exertion from a user. An exertion may include any type of movement, pressure change, or applied force from a body part of theuser40. Note thatFIG. 1 describes an embodiment with threesensor systems34,36, and38 for collecting readings from three areas, upper body, lower torso, and lower extremity. However, it is understood that the invention may be implemented less than three sensor systems, i.e., an embodiment with just one or two sensor systems may be utilized.
• Each of the three core exercises are performed with the user seated, in this case on achair42. While seated, the user must typically remain in a relatively upright and neutral position. From the position, theuser40 is instructed bycomputer system10 to perform: anterior/posterior pelvic tilts, involves front-to-back movements of the lumbar spine and pelvis; side-to-side pelvic tilts, using a lateral sway; and/or “pelvic circles” using a circular movement of the pelvis. As noted, pelvic tilt exercises initially can be difficult to perform properly and often there is compensation by other muscles, reducing the effectiveness of the exercises.
• By analyzing data from the threesensors34,36,38, a determination is made whether the user is performing the exercise in a technically correct manner. In this embodiment,sensor34 is affixed to the user's upper body, e.g., torso or shoulders and measures or detects upper body exertions, e.g., forward-back, side-to-side, and up-down motions;sensor36 comprises a seat that theuser40 sits on and detects the user's lower torso (e.g., pelvic, spine, abdomen, etc.) exertions relative to a central neutral position; andsensor38 comprises a foot rest and detects a lower extremity exertion, e.g., foot pressure, force or motion.Sensors39a,39b,39cdepict alternative sensor locations/embodiments for measuring lower extremity exertion.Sensor39ais shown attached to the user's thigh,sensor39bis shown attached to the user's shin, andsensor39cis shown on top of the user's foot. As is evident, the particular location for detecting lower extremity exertion can vary, and any location that is suitable for detecting exertion may be utilized.
• During the performance of the core exercises, there should be little or no upper body motion (as monitored by sensor34), and no lower extremity exertion (as monitored by sensor38). The lower torso region of the user, as monitored bysensor36, should exhibit a specific range of motion depending on the exercise. For instance, while performing anterior/posterior pelvic tilts, there should be an exertion (i.e., pressure, force or motion) change detected in the forward/rear directions, but none in the side-to-side directions.
• In this example, avideo interface device32 is provided to interface with, guide and provide feedback to the user performing the exercises. Although not shown, other devices could similarly be utilized to interface with the user, e.g., keyboard, remote control device, TV, audio, holography, smart phone, tablet, GPS, etc. As the user performs the exercises, sensor data from the three sensors is transmitted via adata interface30 intocomputer system10. Data may be transmitted in any manner (wired, wireless, Bluetooth, etc.).Computer system10 collects and analyzes the sensor data and determines if theuser40 is performing a core exercise correctly. If theuser40 is utilizing incorrect technique, feedback is provided to theuser40 to change/correct the technique.
• Computer system10 includes a coreexercise control system18, which may for example be implemented as a computer program product stored inmemory16 and executable byprocessor12. Coreexercise control system18 generally includes: (1) auser interface system20 that generally provides a suite of interface modes foruser40 including, e.g., a sign-in mode, a set-up mode, a calibration mode, a user training mode, an exercise mode, etc.; (2) adata collection system22 for collecting sensor data streamed in fromdata interface30; (3) ananalysis system24 for analyzing the sensor data; and (4) afeedback system26 for providing information back to theuser40 regarding the performance of the exercise by the user.Computer system10 may also include adatabase28 that may for instance include user specific data (e.g., past exercise regimens, calibration data, interface settings, etc.) and may store data for multiple users.
• As noted, in order to assess whether the user's technique is correct, the threesensors34,36,38 are adapted to collect data about (1) upper body exertion, (2) lower torso exertion, and (3) lower extremity exertion.Sensors34,36,38 may be implemented using any type of sensing devices, and various examples are discussed herein.
• In one illustrative embodiment,upper body sensor34 is implemented with an accelerometer device (such as a Wii remote) strapped to the user's torso. The accelerometer detects roll and pitch of the shoulders and torso to ensure the shoulders are properly positioned. It is understood however, that any device for detecting upper body movement could be utilized.
• Lower torso sensor36 generally comprises a seat that senses exertion, e.g., pressure force or motion, over different points on the surface of the seat. In one embodiment, the distribution of pressure among the sensors monitors the user's center of gravity and movement of the pelvis while the user performs the core exercises. When the exercises are being performed properly, the pressure distribution should follow a consistent pattern. An aberrant change in exertion indicates that the user is improperly compensating during the exercises.
• In one illustrative embodiment shown inFIGS. 2A and B,lower torso sensor36 comprises a cushioneddisc53 with a plurality ofair bladders55, each having a sensor for monitoring its internal air pressure (or force or motion). When the user moves, air pressure (or force or motion) changes are detected and converted to electrical signals. Note that thebladders55 could be filled with any type of fluid, (i.e., liquid or gas).
• FIGS. 7A and 7B depict an alternative embodiment of a Lowertorso sensor system60. Lowertorso sensor system60 includes asensor board62 and apassive cushion64 that rests on top of thesensor board62.Sensor board62 generally comprises a rigid platform that can sense exertions at different points on asurface68. An example of such a device is a Wii Fit Board®. Also included is amechanism68 that communicates sensor readings e.g., via Bluetooth, infrared, etc., to an analysis system, e.g., a Wii console.Passive cushion64 generally comprises a pliable (e.g., rubber, plastic, etc.) material that can be placed onto thesurface68 of thesensor board62. The lowertorso sensor system60 as shown inFIG. 7B can be placed on, e.g., on a chair, with the user seated on thepassive cushion64. As the user performs pelvic exercises, thesensor board62 detects exertions at different points on thesensor board62 and communicates that data for analysis.
• As noted thelower extremity sensor38 monitors exertions of the lower extremity, e.g., lifting or pressing of the feet, thighs or legs during performance of the exercises. An illustrative unit such as that shown inFIGS. 3A and 3B may be comprised ofcontact sensors57 for each foot that detect when exertions under the feet is reduced below or exceeds a preset threshold. As noted, detecting exertions may include detecting force, pressure or motion. There should be little or no movement of the feet when the exercises are performed properly. A detection of lower extremity movement indicates that the user is improperly compensating during the exercises. In an alternative embodiment, a accelerometer, such as a Wii controller, could be affixed to the user's leg, such as that shown by reference numbers39a-cinFIG. 1.
• FIG. 4 depicts an illustrative interface for providing feedback to the user. Abar50 is utilized to depict the position of the upper body and agrid52 is utilized to show a pressure point of the pelvis.FIG. 5 depicts an animated feedback interface in which an avatar of the user is shown performing the exercises. Obviously,FIGS. 4 and 5 depict a few interface examples, and any type, design, layout, device, etc., may be utilized to provide feedback.
• FIG. 6 depicts a flow chart of an illustrative methodology for implementing a sensor based pelvic exercise regimen. First, at S1, the user logs into (or otherwise activates) theexercise control system18 and places himself/herself in a ready position with the sensors engaged. Next, the exercise regimen begins at S2. The user may for instance be instructed and guided through an exercise routine via a video interface. Sensor data is continuously collected and transmitted to thecontrol system18 at S3. Thecontrol system18 then analyzes the data and determines if too much upper body movement is detected at S4, if the pelvic motion is outside expected movement thresholds at S5 and if a foot exertion is detected at S6. If any of these conditions occur, the user is notified via feedback at S7 (e.g., by a video alert, an audio message, a tactile feedback such as a vibration, etc.). If not, more sensor data is collected and the process repeats until the exercise regimen ends.
Further Illustrative Embodiments
• The system described above could also be integrated into the seat of cars (such as taxi cabs), trucks, buses, airplanes, and office or task chairs. In the case where the system was being used by the operator of a vehicle, only the upper body and lower torso sensors would be used. In such an embodiment, a small, portable, handheld (or dashboard mounted) display could be used to provide the user with a prompt as to when it is time to take a break and do the exercises, as well as provide the user with the necessary feedback while the user conducts the exercises (as described above). The system can also record when and how often the user uses the system and if they are compliant with the exercise regimen. This will not only reduce the incidence of low back pain for a worker, but also reduce liability for the employer.
• For workers who spend time sitting in front of a computer, a wireless connection (such as Bluetooth) could be made from the chair to the computer to provide the user with the same type of feedback as described above, but using the computer display rather than a portable one.
• Moreover, although generally described with reference to exercises for strengthening the core, the system and method described herein could be utilized for any exercise in which a user is seated.
