Description
- This application claims the benefit of U.S. provisional application Ser. No. 61/724,592 filed on Nov. 9, 2012 and entitled EXERCISE SYSTEM FOR PHYSICAL REHABILITATION AND FITNESS, which is commonly assigned and the contents of which are expressly incorporated herein by reference.
- The present invention relates to an exercise system for physical rehabilitation and fitness and in particular to an exercise system that combines an extremity exercise system and a work simulator.
- Extremity exercise systems are typically used for isolated joint (sometimes referred to as “open chain”) exercise where the patient is seated in a chair and performs a knee, hip, shoulder, or other pattern against an input adapter on the dynamometer. Examples of single-joint exercises include elbow extension/flexion, knee extension/flexion, and wrist radial/ulnar deviation, among others.
- A second class of exercise devices is work simulators, which are used for multi joint (sometimes referred to as “closed chain”) exercise. In this case, the patient is typically standing and utilizes a dynamometer on a post with various input adapters including a wheel/cable, hand tools, or shoulder tools. In multi joint exercises, the hand or foot is fixed to an input adapter and multiple joints are free to move concurrently in space.
- Examples of multi joint exercises include rowing, push-ups, and leg extension, among others.
- It would be desirable to provide an improved exercise system that can be used for both extremity exercises and work simulator exercises
- The present invention describes an exercise system for physical rehabilitation and fitness that combines an extremity exercise system and a work simulator system.
- In general, in one aspect, the invention features an exercise and rehabilitation system including a patient positioning system, a dynamometer, an electronics module, a computer, and a communications module. The electronics module includes a servo-amplifier and a controller and the controller receives torque and position data from the dynamometer, computes the control signal for the servo-amplifier, receives high-level control settings from the computer and communicates torque and position data to the computer. The communications module is configured to communicate with the electronics module, and the computer.
- Implementations of this aspect of the invention may include one or more of the following features. The computer communicates with the communications module and the electronics module via a wired or wireless connection. The dynamometer includes a first shaft extending along a vertical axis and is rotatable around the vertical axis and a second shaft extending along a horizontal axis and is rotatable around the horizontal axis, and the horizontal axis intersects the vertical axis. The exercise and rehabilitation system further includes a wheel attachment configured to be removably attached to the second shaft and to allow a user to perform work simulator exercises while standing in the open space around the common platform. The exercise and rehabilitation system further includes one or more attachments configured to be arranged inline with and removably attached to the second shaft and to allow a user to perform extremity exercises while seating in the patient positioning system or work simulator patterns when standing in the open space around the common platform. The computer includes and runs an application program and data storage, and provides a user interface and report generation. The dynamometer is movable along the vertical axis and tiltable relative to the vertical axis. The exercise and rehabilitation system may further include a removable vertical lifting attachment and a removable torso rotation attachment. The exercise and rehabilitation system may further include a biometric system that transmits biometric data to a data monitoring and recording computer. The biometric system includes an Electromyography (EMG) device and/or an Electrocardiogram (ECG/EKG) device. The communications module may also communicate with the biometric system. The electronics module transmits torque and position data and controller status data to the communications module and the biometric system transmits biometric data to the communications module. The communications module appends the biometric data to the torque and position data and controller status data and generates a resulting data package and transmits the resulting data package to a data monitoring and recording and control computer via a digital interface. The data monitoring and recording and control computer may also communicate command data to the electronics module and the biometric system via the communications module. The communications module may also transmit data to multiple computers. The patient positioning system, the dynamometer, and the electronics module are separate from each other and are supported onto a common platform. The computer is separate from the dynamometer, the patient positioning system and the electronics module and is supported in a cart that is separate from and movable around the common platform, thereby providing open space around the common platform.
- In general, in another aspect, the invention features an exercise and rehabilitation system including a patient positioning system, a dynamometer, an electronics module, and a computer. The electronics module includes a servo-amplifier and a controller and the controller receives torque and position data from the dynamometer, computes the control signal for the servo-amplifier, receives high-level control settings from the computer and communicates torque and position data to the computer. The patient positioning system and the dynamometer are separate from each other and are supported onto a common platform. The electronic module and the computer are separate from the dynamometer and the patient positioning system and are supported in a cart that is separate from and movable around the common platform, thereby providing open space around the common platform.
- Among the advantages of this invention may be one or more of the following. There is no need for two separate exercise systems. The exercise system of this invention occupies less space than two separate exercise systems.

FIG. 1A , a prior artextremity exercise system 99 was designed to provide extremity (knee, hip, shoulder, and trunk) testing and uses an in-line design. Thisprior art system 99 includes apatient positioning system 110, adynamometer 130 and anelectronics module 120. Theelectronics module 120 includes a servo-amplifier, a controller and acomputer 150. Thepatient positioning system 110, thedynamometer 130, theelectronics module 120 and thecomputer 150 are rigidly attached to aplatform 140. Thepatient positioning system 110 includes anadjustable seat 111 which provides patient positioning relative to thedynamometer 130 and stabilization through aseat belt 112 and Velcro straps 113. Thedynamometer 130 includes a servo motor and a gear box, an instrumented shaft and a set of input adapters. The servo motor and gearbox provide force, position or velocity-based resistance. The instrumented shaft provides torque data and a motor encoder provides position data to the controller. The set of input adapters accommodates various testing patterns including knee, hip, wrist, and shoulder, among others. -
FIGS. 1B and 1C depict work simulator exercise systems. Both the extremity exercise system and the work simulator system include a dynamometer and an electronics module. Their differences are typically the following: The extremity exercise system includes a patient positioning system which is rigidly linked to the dynamometer. The dynamometer can be raised and lowered from 3′ to 5′ above the floor and the measured forces and speeds are typically in the 5 to 500 ft-lbs and 5 to 500 deg/sec ranges. In the work simulator system, the patient stands in front of the dynamometer. The dynamometer can also be raised and lowered. - The improved exercise system of this invention provides the functionality of both an extremity system and a work simulator system.
- Referring to
FIG. 2 , the improved exercise system of thisinvention 100 includes apatient positioning system 110, adynamometer 130, anelectronics module 120 and acomputer 150. Thepatient positioning system 110, thedynamometer 130 and theelectronics module 120 are positioned and supported onto aplatform 140. In this embodiment, thecomputer 150 is located in acart 152 that is separate from theplatform 140. This placement of thecomputer 150 provides improved usage space at thefront area 102 of thesystem 100. In other embodiments, theelectronics module 120 is also positioned onto thecart 152. This embodiment also provides enough space at thefront area 102 for the user to stand and perform the work simulator exercises. - The
electronics module 120 includes a servo amplifier and a controller. Thecomputer 150 is separate from theelectronic module 120 and includes amonitor 151. The servo amplifier provides a drive signal to the motor. The controller reads the torque and position data from the dynamometer, computes the control signal for the servo amplifier, receives high-level control settings from thepersonal computer 150 and communicates measured torque and position to the computer. Thecomputer 150 runs an application program, provides a user interface, data storage, and report generation. - Referring to
FIG. 3 , awheel 160 withcable drive 166 and alower pulley 165 are attached to thedynamometer 130 ofsystem 100. This attachment allows theuser 90 to perform work simulator exercises in front of theexercise system 100. In this embodiment, thedynamometer 130 is rotatable aroundx-axis 134 by 360 degrees, and it can be raised lowered, and tilted. Thedynamometer shaft 138 is rotatable around y-axis 135 by 360 degrees. - In addition to the above-mentioned usage and attachment, the
dynamometer 130 can be used as a drive/measurement source to a number of additional attachments. These additional attachments include a vertical lifting system, and a torso rotation system, among others. In the torso rotation system the cable from a traditional rotation weight stack machine is routed through thewheel mechanism 160, and the traditional weight stacks are replaced by the system's resistance and measurement functions. This same functionality of replacing the traditional weight stacks by the system's resistance and measurement functions is also used in the vertical lifting system. In other embodiments, the connection between the dynamometer controller and thecomputer 150 is wireless, i.e., Bluetooth, or other wireless network connections, as shown inFIG. 6 . The wireless connection between the controller and thecomputer 150 eliminates the need for cabling between thecomputer 150 and theelectronics module 120 and increases the usability of the system. Furthermore, anintelligent communications module 250 is added in thedevice 100, as shown inFIG. 7B . The addition of thecommunications module 250 enables the opening of multiple communication channels. These additional wireless communication channels allow communications between the controller and the computer the therapist is using, broadcasting feedback to an iPad™ or other tablet computer that the patient is using, and acquiring biometric system data from wireless modules which are then synchronized with the torque, position and velocity data from theexercise system 100. - As was mentioned above, in a prior
art exercise system 99 theelectronics module 120 includes a servo amplifier, a controller and acomputer 150. The controller reads the torque and position data from thedynamometer 130, computes the control signal for the servo amplifier, receives high-level control settings from thepersonal computer 150 and communicates measured torque and position to thecomputer 150. The computer runs an application program, provides a user interface, data storage, and report generation. - It is often desirable to correlate the torque and position data from
system 99 with biometric data from variousbiometric sensors 226. Thus,prior art exercise 99 system may also be combined with abiometric system 200, as shown inFIG. 7A . The controller in theexercise system 99 transmits the torque and position data from thedynamometer 130 to thecomputer 150 via adigital interface 202. Thedigital interface 202 may be an RS232, a USB, Ethernet or Bluetooth interface, among others. Thebiometric system 200 includes an Electromyography device (EMG) and/or an Electrocardiogram device (ECG/EKG), among others. The EMG and EKG devices are connected to EMG andEKG sensors 226. Thebiometric system 200 transmits biometric data to a data monitoring andrecording computer 208 via thecommunications module 250 and adigital interface 212. Thedigital interface 212 may be an RS232, a USB, Ethernet or Bluetooth interface, among others. Researchers are interested in correlating the torque and position data fromcomputer 150 with the biometric data fromcomputer 208 in order to evaluate the efficacy of an exercise program. However, given the uncertainties in the operating system response time it is not feasible to correlate reliably the torque and position data fromcomputer 150 with the biometric data fromcomputer 208. In order to solve this problem, in prior art systems, the controller in theexercise system 99 adds a set ofanalog outputs 210 which feed the torque and position data fromsystem 99 to analog inputs on thebiometric system 200 via ananalog interface 211, shown inFIG. 7A . However, the conversion of the torque and position data from digital to analog and then back to digital format introduces noise and compromises the integrity of the data. Furthermore, the controller digital status data which are transmitted via thedigital interface 202 tocomputer 150 are not included in the data stream from thebiometric system 200. Also, any additional data streams would require additional analog inputs to thebiometric system 200. - Referring to
FIG. 7B , in theimproved exercise system 100 of this invention, controller digital status, torque andposition data 230 are transmitted via adigital interface 224 directly to acommunications module 250. Similarly, thebiometric system 200 communicatesbiometric data 206 to thecommunications module 250 via adigital interface 212. In this case thecommunication module 250 includes digital ports (USB; RS232, Ethernet or Bluetooth interface, among others) and is placed between the controller, thebiometric system 200 and thecomputer 220. Thebiometric system data 206 are appended to the controller digital status, torque andposition data 230 and the resultingpacket 222 is forwarded tocomputer 220 via thedigital interface 213. Command data that are addressed to the exercise system controller and/or thebiometric system 200 fromcomputer 220 also pass through thecommunication module 250 in the opposite direction. The improved system of this invention provides improved signal quality by eliminating the digital to analog and then back to digital data transformation. Additionally by correlating the data in thecommunications module 250, the operating system uncertainty and the requirement to concurrently manage multiple data channels in thecomputer system 220 are eliminated. The system can be readily extended by connecting additionalbiometric sensor devices 200 to thecommunications module 250. The system can also be extended by connectingmultiple display systems 260 to thecommunications module 250. - Several embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
