Definitions
- the present invention relates to a portable device for rehabilitating a user affected by a disability with difficulties in executing simultaneous extension and lifting functions.
- the device is particularly suitable for use in physiotherapy and / or rehabilitation programs for the treatment of neurovascular or musculoskeletal lesions or diseases of the upper limb.
- the alteration may be due to neurological diseases such as stroke (see, for example, statistics updated to 2007 of heart attacks and diseases of the American Heart association and the American stroke association), or it may be due to musculoskeletal injuries. In both cases the disease can result in a decreased range of motion, muscle weakness, loss of speed and / or reduced coordination of the affected limb.
- neurological diseases such as stroke (see, for example, statistics updated to 2007 of heart attacks and diseases of the American Heart association and the American stroke association), or it may be due to musculoskeletal injuries. In both cases the disease can result in a decreased range of motion, muscle weakness, loss of speed and / or reduced coordination of the affected limb.
- Physiotherapy is known to be effective in reducing the degree of disability (Nancy ByI et al., Neurorehabilitation and Neural Repair, vol. 17, n ° 3, 176-191 (2003); Darlene Hertling, published by Lippincott Williams and Wilkins, 2005).
- the recently published research work (Liesbet De Wit et al., Stroke. 2007; 38; 2101) confirms that better results are obtained in rehabilitation in those health centers in which patients receive more treatment per day for prolonged periods of time .
- physiotherapy is only administered in hospitals or specialized health centers. A physiotherapist causes the patient to perform a series of repeated exercises during training sessions that generally have a limited number and duration due to the availability of therapists and the cost.
- Robotized devices have the possibility of improving this situation.
- An intelligent robot mechanically coupled with the patient's arm can be used to help the patient carry out the exercises during the rehabilitation period, thus increasing the time invested in rehabilitation training.
- the robot sensors can be used to assess the degree of the alteration at the beginning of the therapeutic cycle and monitor the progress.
- a series of robotic devices have been developed in recent years for both academic and commercial purposes. For example, at the University of Washington, Seattle, USA. an upper limb exoskeleton powered with 7 degrees of freedom has been developed as a rehabilitation / assistance device to treat dysfunctions that involve a loss of strength in the upper limb.
- Baker discloses a therapeutic device for rotation of the wrist rehabilitation Ia Ia wrist.
- Reinkensmeyer et al. (US Patent No. 6,613,000 (2003)) describes a computer-based system that provides a treatment for arm movement for patients with sensory disturbances that can function through the web and provides personalized therapeutic exercise programs.
- Diaz et al. (US Patent No. 2005/0273022 A1 (2005)) describe a portable medical device for joint rehabilitation by means of a continuous passive movement.
- Dewald et al. describe a system for the rehabilitation of dysfunction in the coordination of the limbs induced by the force of gravity after a stroke or other neurological disorders.
- the results of clinical and study trials carried out with robots such as MIT-Manus indicate that robot treatment is safe, well accepted by patients and useful (see for example Krebs et al., Technol. Health Care 7, 6 (December 1999), 419-423.).
- the robotic device should be economical enough for health centers to adopt it to a large extent. Simplicity of use is also a matter in case patients have to use the robotic device at home.
- the "domestic use” feature also requires the portability of the device.
- the devices and / or patents described above can be broadly classified into two categories: (1) expensive and non-portable devices that can be used to implement a series of different rehabilitation programs given their complex structure; (2) simpler, more specialized devices that can be used for a limited number of rehabilitation programs.
- US Patent No. 2007/0021692 describes a system for performing induced movements of the members.
- the trajectories of the hand or foot are recorded by position sensors and the pressure exerted by the member can be recorded.
- WO 99/61110 describes a system for training rapid extension movements (anticipation movements).
- the system incorporates measurement of the position (hand, arm, joints), measurement with EMG and user feedback.
- US Patent No. 7,311,643 describes a portable exercise board for the shoulder and upper limb. It provides means to move a handle in a plane with a discretely variable coefficient of friction.
- Japanese Patent No. 2007185325 describes a system for performing extension exercises on a table. The system is portable and provides measurement of the position and force exerted by the user on a handle. The position of the handle does not provide information about the configuration of the arm.
- Japanese Patent No. 2002272795 describes a rehabilitation device for the upper limb that includes a measurement of the position and the force exerted by the user on a handle (transport device) and feedback means. The system requires an instrument table with guides on which the transport device can move.
- Japanese Patent No. 2004008605 describes an apparatus for member rehabilitation training. It provides means to measure the force exerted by a member on a fixed device together with means to provide feedback to the user, such as video, sound, vibration). It is an objective of the invention to provide a simple and economical device that allows the user to make extension movements in a wide work area.
- the portable device for rehabilitating a user affected by a disability with difficulties to perform simultaneous extension and lifting functions comprises an arm support to which the user's forearm can be attached and means to allow the movement of the support for The arm on a surface. It also includes means for monitoring the movement of the arm support, that is, the position / speed / acceleration and orientation thereof. Finally, it comprises means for detecting a force exerted by the user's arm on the arm support in a direction orthogonal to the surface.
- the proposed device is in fact a mobile robot instead of being a fixed device, a device based on a frame or a device that moves on a rail or guide. This provides portability. It also addresses the needs of special rehabilitation techniques through modularity.
- the device according to the present invention allows the user to perform extension movements in a wide area of work having the supported forearm and subject.
- the fact that the forearm is supported and attached to the device allows a better control of the training movements of the shoulder, avoiding uncontrolled trajectories at the level of the elbow that are possible in case of only grasping a handle.
- detecting the rotation and position of the device due to the fact that the forearm is fixed to the device, guarantees a better quantitative assessment of the three-dimensional position of the arm.
- the device is designed for elbow and shoulder training, although it can also be used to train the wrist and grip by adding specific modules.
- the number, duration, intensity and type of training session can be controlled by software running in the central processing unit of the device.
- the network capabilities of the device according to a preferred embodiment of the invention allow its use in telerehabilitation environments, in which the user and the physiotherapist are not in the same place, although the physiotherapist can monitor and change the parameters of the rehabilitation program in any time that is required.
- one of the problems that is solved by the device according to the present invention is related to the assessment and treatment of dysfunctions of the upper limb due to anomalous synergies between shoulder abduction and elbow flexion activated by the weight of the member himself.
- Patients with chronic stroke are an example of individuals with an alteration who have generations of abnormal motor torque patterns.
- a subject with an alteration tries to make an extension away from the body and has to completely compensate for the gravity that acts on the limb, its extension movement is involuntarily linked to an elbow flexion. This prevents the subject from performing the extension movement in a natural way.
- motor learning capacity is still present in patients with chronic stroke, which could allow recovering a more functional pattern of shoulder and elbow activation. (EIIiS et al., Muscle Nerve. August 2005; 32 (2): 170-8).
- a subject can perform extension movements having the arm supported and measuring the degree of lifting force that can be exerted, preferably by means of a force sensor.
- the subject is also provided with feedback about the position and orientation of the forearm, and the lifting force exerted. He / she can then engage in extension and elevation movements to perform some functions represented in a virtual scenario that can be used to train your functional recovery of the correct synergies of the elbow / shoulder.
- the position and the lifting force can be used to control two degrees of freedom in a game-like scenario shown on an LCD screen. Therefore, the invention can be used to provide a quantitative assessment of the condition of the subject at the start of rehabilitation training and to provide training in an effective manner.
- the invention provides a training and measurement device and procedures for training and / or self-training and assisting individuals who have neurological or musculoskeletal disorders that result in the partial loss of the ability to move the upper extremities.
- the device is preferably modular allowing to reach a different degree of functionality / complexity of the system.
- the device is a mobile robot of light weight and small size that is operated on a table (or any other suitable surface).
- the robot is equipped with a base platform that has conventional wheels or spherical wheels.

- the mobile base is equipped with sensors, such as optical tracking sensors, which allow the robot's position / speed / acceleration monitoring and therefore also its arm support.
- the device comprises fastening means for fastening the forearm to the arm support, in which the fastening means are selected from the group of: sailboat ribbons, pneumatic bracelets, and 3D printed bracelets adapted to the shape of the forearm of a single Username.
- a feedback interface is provided, usually a video screen (although it could be used for video, audio, touch or a combination thereof) so that the user can monitor his own activity.
- the device is part of a system equipped with a processing unit, a storage unit and a cable / wireless communication unit.
- the robot is designed so that it can be operated by patients.
- An auxiliary system can be provided that communicates remotely with the robot through a network protocol.
- This auxiliary system is designed for use by the optional staff and provides data storage and processing means along with the appropriate software to analyze and interpret the data collected and sent by the robot during the rehabilitation sessions.
- a measurement procedure can be implemented. The procedure is based on the measurement and recording of the movement of the mobile base of the robot and of the motor / force pairs applied by the user in the arm support.
- the rehabilitation training procedure takes advantage of software that interactively instructs the patient about the function that the mobile robot must continue to use.
- the patient continuously receives feedback about their performance in a kind of interactive game.
- the type of exercise to be performed can be decided remotely by the health center staff and / or constantly adapted to the user's performance.
- the complete system can be modular, so that the embodiment described above can be integrated by extension modules to extend its functionality.

- server 100 specifically designed to allow group treatment.
- several users can carry out the training at the same time, receive information about the activity of others and compete or collaborate as part of the training.
- the group treatment could take the form of an online CRPG (online computer role playing game) or MMORPG (massively multiplayer online role-playing game, massively multiplayer online role-playing game) online .
- Figure 8 represents a block diagram of a concept of simultaneous rehabilitation of this type.
- IU 1 ... n users affected by a disability use the part of the system described in Figure 6 and called 'health or domestic center'.
- the medical staff in the health centers 90 uses the part of the system described in Figure 6 and called the 'health center'. In this way various training modalities are made available:
- the user can connect to a "virtual rehabilitation center" (perhaps within a virtual Internet-based world such as Second-Life or others) and follow the instruction of a therapist along with other users;
- the user can carry out the rehabilitation function as part of a team game with other users who are also training;
- the user can play a game together with people not affected by a disability who use conventional input devices to interact in the game. All these modalities have the possibility of introducing a "recreational" or “fun” dimension in the rehabilitation routine that can improve the acceptability and the result of the treatment itself.
- training involves the execution of an extension movement combined with an elevation of the arm (shoulder abduction).
- the user has his forearm fixed to the portable device 10.
- the device can move freely on the surface of a table.
- the extension movement causes the device to move on the table by registering the position sensors 18 the relative orientation and position of the portable device 10 and thus of the support 12 for the arm and the forearm attached to it.
- the user will not be able to perform the shoulder abduction plus the extension correctly without help due, for example, to abnormal synergies developed after a stroke.
- the arm support Ie will allow to compensate for these synergies since it is not obliged to lift the weight of the arm.
- the support 12 for the arm has a fixed position with respect to the mobile base that allows isometric training of the shoulder abduction.
- the force exerted by the forearm on the arm support is monitored by the force sensors 13 inserted in the connection between the arm support and the mobile base. Therefore, the user You can measure your progress in the ability to raise the arm while performing an extension movement because you can see a decrease in the force measured by the force sensor. In the ideal case, the user should be able to fully support the weight of his arm while performing the extension function.
- the vertical displacement of the arm support with respect to the base can be controlled by a damping system or can be assisted by some actuators, so that more complex rehabilitation patterns can be implemented.
- the measurement of force, orientation and position constitute inputs that can be used to interact with the training software as a game.
- the software can be very simple, as in 2D play. For example, the user moves in a simple maze using the position and orientation of the forearm while performing functions trying to raise the arm (overcome obstacles, reach bonus points that hang, etc.).
- the device can be used to interact in a multi-user online game and / or an Internet-based virtual world, with other users affected by a disability or with healthy users. In this way, the social and recreational dimension added to rehabilitation training could accelerate it and / or make it more effective.
- a computer program may be stored / distributed on a suitable medium, such as an optical storage medium or a solid state medium supplied jointly or as part of other hardware, although they may also be distributed in other forms, such as over the Internet or other wireless or cable telecommunications systems.
- a suitable medium such as an optical storage medium or a solid state medium supplied jointly or as part of other hardware, although they may also be distributed in other forms, such as over the Internet or other wireless or cable telecommunications systems.
