Description

[0001] SYSTEM THAT ALLOWS COLLABORATION IN THE RECOVERY OF MOBILITY IN PATIENTS WHO ARE UNABLE TO MOVE THEIR UPPER OR LOWER EXTREMITIES

[0002] Technical Aspect of the Invention

[0003] The present invention relates to the field of electronic devices that assist in the recovery of mobility in patients who are unable to move their upper or lower limbs due to a pathology, accident, agenesis, or amputation of an upper or lower limb, specifically with a system comprising four devices that form part of a system: the first device of the system consists of a removable intraoral device in the form of a mouse, the second device consists of a headband to be placed on the head of a patient, the third device houses the system inside a smaller box to be placed on the edge of an elastic band, which will be placed on the thigh of a patient, the fourth device houses the system inside a second smaller box to be supported by the ear of a vehicle driver.

[0004] Background of the Technique

[0005] The following discussion of the prior art is intended to present the invention in an appropriate technical context and allow its advantages to be properly appreciated. However, unless clearly stated otherwise, reference to any prior art in this specification should not be construed as an express or implied admission that such art is widely known or forms part of common knowledge in the field of electronic devices that enable the restoration of mobility in patients who are unable to move their upper or lower limbs. There is a continuous demand for a relatively simple and inexpensive device to manufacture for this purpose.

[0006] It is estimated that two-thirds of people who have suffered a stroke experience lasting effects that impact their quality of life. Stroke rehabilitation is a complex process requiring a multidisciplinary team of specialized professionals (physicians, physical therapists, nurses, occupational therapists, speech therapists, neuropsychologists, and nutritionists). Currently, rehabilitation practices are based on a combination of evidence and consensus, with most recommendations derived from international stroke rehabilitation guidelines. The objective of this review is to align international rehabilitation recommendations with daily practice, aiming to standardize recommendations and reduce variability in the practices employed.This study reviewed the literature on stroke rehabilitation guidelines published in the last 10 years, with each section reviewed by specialists in their respective fields. The review analyzed the time required and organization for rehabilitation, recommendations for motor, cognitive, and visual rehabilitation, treatment of dysphagia and nutrition, management of comorbidities (venous thrombosis, skin ulcers, pain, psychiatric disorders, osteoporosis), and the tasks necessary to facilitate a return to activities of daily living.

[0007] Motor rehabilitation in stroke

[0008] Motor rehabilitation of lower limbs and gait

[0009] One of the most significant neurological deficits in stroke patients is gait disturbance, making motor rehabilitation essential for achieving greater independence. Intensive, repetitive, and task-oriented mobility training is recommended for those with gait disturbances. This training includes activities such as transfers (wheelchair to bed or bed to chair), standing, sitting, climbing stairs, and turning. Circuit training is a type of group intervention in which the patient rotates through different exercise stations focused on the repetitive practice of functional tasks. Treadmill exercises added to conventional rehabilitation, such as walking on the floor, can be beneficial, although no significant differences have been demonstrated between the two in ambulatory patients.However, mechanically assisted walking with body weight support (electromechanical gait trainer, robotic devices) may be considered useful in early stages (<3 months) only for those who are not yet ambulatory. It is also important to include selective motor rehabilitation using different manual techniques to add stimuli (multisensory stimulation) and improve the quality and comfort of motor recovery. Examples of manual techniques include proprioceptive neuromuscular facilitation (PNF) stretching and the Bobhath method. The latter involves inhibiting abnormal muscle tone and movement patterns, facilitating normal movement, and stimulating muscle in cases of hypotonia or muscle inactivity.

[0010] The use of ankle-foot orthoses (AFOs) can improve gait. They are recommended for individuals with dorsiflexor weakness and foot drop. Functional electrical stimulation (FES) is an electronic orthosis that also promotes gait recovery by being applied to the ankle dorsiflexor muscles.

[0011] Motor rehabilitation of upper limbs

[0012] Functional tasks should be based on task-specific training, improving action performance and promoting repeated learning of a motor skill. All patients should be trained in routine daily living activities, with or without assistive devices. Constraint-induced movement therapies are reasonable to use (e.g., restricting compensatory trunk movements can promote proximal rehabilitation). Strengthening exercises can be used as an adjunct to functional tasks. In those with severe paralysis or weakness, rebotic rehabilitation may be considered, primarily focusing on activities of daily living without a clear benefit to strength. Multisensory stimulation, as provided by the Bobhat and PNF concepts and methods, is also beneficial in promoting movement selectivity.13

[0013] Functional electrical stimulation (FES) can be considered a treatment for subluxation and pain in the hemiplegic shoulder within the first few months after a stroke. It is also applied to the muscles of the hand and wrist in combination with task-specific training. The use of virtual reality and techniques based on practice or mental imagery can be considered complementary to upper extremity rehabilitation. Mirror therapy is another complementary technique that may be useful.

[0014] Several aspects are relevant to achieving these objectives, such as the effectiveness of the device used to restore limb mobility, and patient comfort, ensuring ease of use and avoiding cumbersome mechanisms and devices. The design of the system based on a headband and an intraoral mouse, as described in the invention, can influence and improve some of the previously identified aspects. The removable intraoral mouse device can assist, for example, a patient who needs to use a computer again, the headband can help a patient walk again, and many other actions that the patient is currently unable to perform due to the high cost of the devices.

[0015] For information on the state of the art, see US patent document No. US10688274B1 related to systems and methods for multimodal and non-invasive stimulation of the nervous system.

[0016] Systems and methods are provided for combining multiple stimulation modalities to significantly increase the effectiveness of non-invasive stimulation. Multiple sensor and stimulation devices and modalities can be combined into a single compact unit, minimizing the need for additional sensors or stimulation devices. The system features several subunits, called sensory and stimulation devices (SSDs), which are integrated into a headset configuration. The system is controlled by a centralized controller that communicates with all the SSDs and with an external computer system that delivers learning material synchronized with the stimulation delivery and the collection of user responses based on psychological cues.

[0017] Another example is found in US Patent No. US1 1285325B1, related to non-invasive neuromodulation (NINM) for the rehabilitation of brain function in a patient suffering from neuronal impairment. Stimulation is provided to the sensory surfaces of the face and / or neck, or more generally to areas of the body that stimulate the trigeminal nerve, while the patient performs an activity designed to stimulate a brain function to be rehabilitated. The simulation can then continue after the activity is completed. It has been found that the patient's performance of the activity improves after the stimulation has ceased. Furthermore, it tends to improve to a greater extent, and / or for a longer period, when post-activity stimulation is applied, compared to when post-activity stimulation is not applied.

[0018] However, due to the high costs of treatments and the different devices for rehabilitation after stroke, ischemia or post-accident physical therapy, there is a need in the technique for simpler devices that are accessible to all types of patients, mainly due to the high cost of treatments.

[0019] Summary of the Invention

[0020] The applicant has noted that the known technique has some drawbacks, mainly the complexity and high cost of the devices currently available.

[0021] An object of the present invention is to mitigate, alleviate, or eliminate one or more of the deficiencies and disadvantages of the art previously identified individually or in any combination, and to solve at least the aforementioned problem, by providing a system comprising an electronic device especially suitable for the rehabilitation of a post-stroke patient or a patient undergoing therapy for an accident. This electronic device can be incorporated in different modalities, such as a headband around the patient's head, an elastic band to be placed on a patient's thigh, an indicator of loss of balance or drowsiness for a carrier, acoustically alerting the user's ear, or a removable intraoral device in the form of a mouse operated by a patient's tongue, intended to:

[0022] - Recovery of head control

[0023] - Gait retraining

[0024] - Communication

[0025] - Postural re-education

[0026] - To warn a driver of drowsiness or inattention to the road.

[0027] The system comprises four devices: the first is a removable intraoral mouse-like device. When connected via this device, it assists in the rehabilitation of individuals who, due to illness, accident, agenesis, or amputation, are partially or totally unable to move their upper limbs. The second device is a headband worn on the patient's head. The third device houses the system inside a smaller box attached to the edge of an elastic band, which is placed on the patient's thigh. When the device is in use, this box assists in the rehabilitation therapy of post-stroke patients, patients with cerebral palsy, intubated patients, or patients with tracheostomies undergoing therapy.The limited movement of the arm, hand, leg, foot, or head in these patients is interpreted by the device, which associates each movement with a word, phrase, or sentence that is easily loaded according to their needs, thus enabling the patient to communicate.

[0028] The device becomes a programmable alarm, providing real-time monitoring of work and rest periods. This allows for tracking improvements and preventing the patient from adopting the poor posture characteristic of their condition in daily life, thus generating gradual and visible progress. For example, the device, placed on the leg, reads leg rotation and knee flexion, enabling the programming of appropriate alarms based on each change in gait, all aimed at achieving a normal gait. Many of these patients suffer from poor head control, which impacts their improvement when using the aforementioned principles. In amputees with prostheses, it retrains their gait to prevent the development of irreversible, poor posture patterns.The fourth device houses the system inside a second, smaller box to be supported by the ear of a vehicle driver, intended for people with poor posture due to the frequent use of various electronic devices, such as tablets, mobile phones, computers, etc.

[0029] When driving a vehicle, audible alarms warn of time and head movement, indicating when the user is in a situation of distraction, danger, and others.

[0030] The intraoral mouse-like device can be held inside the mouth to function as a mouse for communication with a PC or mobile device, via Bluetooth or a wired USB connection. Additionally, it can be connected to the steering joystick of a wheelchair to control the forward, backward, and turning movements of the wheelchair using the oral controller.

[0031] The device can be positioned inside a headband or headband for head and postural control and to guide the patient in therapy for the recovery of gait or lower limb movements.

[0032] It was designed and developed to improve the rehabilitation and recovery monitoring of patients with TBI or stroke with muscle weakness in the neck and can be used without major difficulties during a patient's normal day.

[0033] For the treatment and assistance in the therapy of quadriparesis, quadriplegia, agenesis, amputation, cerebral palsy are some of the pathologies in which the patient is partially or totally prevented from moving the upper limbs.

[0034] On the other hand, it also targets patients with traumatic brain injury (TBI), stroke, prolonged therapy, or any condition that causes lack of head control due to muscle weakness. It also helps correct a common consequence of gait difficulty following a stroke. Brief Description of the Figures

[0047] The present invention will now be described with reference to the following embodiments, which are to be considered in all respects as illustrative and not restrictive. In the figures, the corresponding features within the same embodiment or common to different embodiments have been assigned the same reference numbers.

[0048] The system comprises four devices, the first (I) houses the system inside a removable intraoral mouse-like device (1) to be inserted into the mouth (2) of a patient (3) controllable by means of the muscular movements of the tongue (4).

[0049] The second (II) houses the system inside a headband (5) to be located on the head (6) of a patient (3), to assist in the recovery of movement of the upper limbs (7) and head (6), through interaction and movements on the X, Y, Z axes in conjunction with the system.

[0050] The third (III) houses the system inside a smaller box (8) to be placed on the edge of an elastic band (9), which will be located on the thigh (10) of a patient (3) in order to assist with the rehabilitation of the gait and posture of the lower limbs (11).

[0051] The fourth (IV) houses the system inside a second, smaller box (12) to be supported by the ear (13) of a vehicle driver user, so as to operate as an acoustic warning of deviation from the path, tilting or turning of the head (6).

[0052] In Figure 1, the intraoral electronic device (1) can be observed, which operates as a mouse for a PC, Tablet, Notebook (14) or any device connected to these appliances, which is housed within a casing and plate that can be accommodated by the teeth, made of harmless plastic material (15) to be placed inside the oral cavity or mouth (2), the device comprises:

[0053] - a casing made of harmless material (15)

[0054] - a depressor piece (16)

[0055] - a piece in the form of lingual push buttons (17) activated by the patient's tongue (4), - a second, longer push button (18), where the action of the patient's tongue (4) pressing the lingual push buttons (17) and the depressor piece (16) allows the movement of a cursor (19) on a computer, tablet, or notebook (14), the movement of the cursor (19) being directed on the X and Y axes by the movement of the patient's head (6) and the clicks of either the right or left mouse button, activated with the tongue (4), additionally allowing control of a joystick controller (20) of a wheelchair (21) to facilitate its handling. It should be noted that the connection for communication with the PC, tablet, or notebook (14) can be by means of a USB cable (U) or wirelessly (I), by means of a Bluetooth transmitter / receiver (22).

[0056] The communication of both the transmission of the order and the reception TX / RX of the order to execute a command or movement, is carried out by means of an Android device or operating system by downloading the application (A).

[0057] The electronics interpret the movement of different parts of the body according to the required function; this data is received by the PC, Tablet, Notebook (14), and the application will interpret and process the required movement.

[0058] The outer casing and plate (15) made from an innocuous plastic material where the electronic components are housed, is located on the outside of the mouth (2) of the patient (3).

[0059] The housing and intraoral plate (15) comprises two lingual push buttons (17) rigidly attached to the rectangular plastic housing and plate (15), on the opposite side of which are located two arc-shaped portions, an upper (23) and a lower (24) which act as supports for the upper and lower dentures of the mouth (2) of the patient (3) in order to hold the intraoral device like a mouse (1) ergonomically and comfortably inside the oral cavity or mouth (2).

[0060] The intraoral electronic device (1) that operates as a mouse for a computer, tablet, notebook (14) or any device connected to these devices, has a single body (25), which is divided into three parts:

[0061] The smaller external box (26) located outside the patient's mouth (3) houses the electronic components.

[0062] The casing and intraoral plate (15) in which the two upper (24) and lower (25) arch-shaped portions are located, which are fixed and held between the patient's teeth and lips or just the teeth (3).

[0063] The rectangular plastic plate (15) on which the two trigger switches (23) are located, activated by the tongue (4) of the patient (3).

[0064] The electronics of this intraoral mouse-like device (1) are divided into two circuits (27 and 28). The first, the transmitter circuit (27), is installed in the various housings and boards (15) that contain the electronics, and the second, the receiver circuit (28), is housed inside a housing and board (15) connected to the USB port of the PC, tablet, or notebook (14). TX / RX communication (data transmission and reception) between the two circuits (27 and 28) is carried out via Bluetooth wireless communication (I) or wired communication via a USB cable (U).

[0065] The operation of these electronic devices (27 and 28) is as follows: in the belt or casing (15) there is housed a board containing an accelerometer and a three-axis gyroscope (MPU6050) (29) which obtains the values ​​of the angular velocity at which the belt or casing (15) moves, these are received by the Arduino Nano board (30) which conditions them, assembles them into a frame and sends them to the Bluetooth module HC05 (31).

[0066] The pattern assembled by the Arduino Nano board (30) also includes the values ​​of the left and right click states of the tongue trigger switches (17). These are small (normally open) switches located inside the mouth (2) of the patient (3) and are activated by pressing or pushing them with the tongue (4) of the patient (3).

[0067] The plot is finally composed of the following four values: Angular velocity value of the X axis, Angular velocity value of the Y axis, left click state (17), right click state (17a) and of each switch respectively.

[0068] On the other hand, the second receiver circuit (28) is connected to the USB port of the PC, tablet, or notebook (14). This circuit has a Bluetooth module that receives the data stream emitted by the transmitter circuit module (27). This information is then fed into the Arduino Micro (32), which, through programming, allows cursor movements (19) and the reception of command clicks from the PC, tablet, or notebook (14). In this way, a fully functional intraoral mouse-like device (1) is obtained, controlled and operated by the patient's (3) head (6) and tongue (4) movements.

[0069] Device that additionally operates as a data interface recorded and managed by the software through the application used on the PC, Tablet, Notebook (14), which by interpreting the data allows visualization of improvements by keeping a graphic record, avoiding regression in the patient's therapy (3).

[0070] The intraoral mouse device (1) additionally has the function of dimming the screen of the PC, Tablet, Notebook (14), after allowing the application to authorize it. Once this permission is granted and the intraoral mouse device (1) is connected, it checks the position on the frontal axis of the patient's head (6) (3) and, according to the angle of this, modifies the brightness of the screen of the PC, Tablet, Notebook (14), dimming it from 100% to 0% while the patient (3) tilts their head (6) forwards until reaching an angle of inclination of 50 degrees.

[0071] The main feature of this intraoral mouse-like device (1) is that it is operated by means of the tongue (4) of a patient (3), which is a muscle that requires less effort and has greater speed in order to facilitate its handling.

[0072] In Figure 4, the second device (II) part of the system can be observed, consisting of a headband (5) to be located on the head (6) of a patient (3) or incorporated into an elastic band (35) to be located on the thigh (10) of a patient (3), in which at its upper end there are located indicator lights of the X, Y, Z axes (39).

[0073] The headband (5) facilitates the recovery of head control in the case of TBI, stroke and / or any pathology that involves muscle weakness, without chronic head control due to a patient's stay in intensive care (3).

[0074] By means of pre-programmed alarms on the (X, Y, Z) axes with light markers or sounds or words that will be emitted through the screen (33) in front of the patient (2) using a PC, Tablet or Notebook or mobile phone (14), the headband (5) allows gait re-education in a patient (3) post stroke and pathologies that present with muscle weakness and in the use of a prosthesis, avoiding a vicious gait sequence. The correct posture of the patient (3) is controlled by darkening the screen of a PC, Tablet or Notebook or mobile phone (14), according to the programmed angle of the head tilt movement alarm (6) up to an angle of 50° of the patient (3). Additionally, each position of the X, Y, Z axes can be programmed with a word so that the patient (3) wearing the headband (5) can receive an audible instruction or command to move any limb of the body or the head (6) of the patient (3).allowing for gait rehabilitation and correction of a patient's poor posture (3) in physical therapy.

[0075] In order to collaborate and improve the rehabilitation and recovery control work of patients with TBI or stroke, to position the head (6) and neck in original position and can be used during the patient's usual day (3), it can also correct gait and posture.

[0076] The headband-like device (5) can be adapted to be positioned inside a box (34) specially suited to be carried by means of an elastic band (35), to be positioned on a thigh (36) of a patient (3), with post-stroke sequelae, who walk in an altered manner, the headband-like device (5), in this mode located inside a casing (34) detects the position of the patient's foot (3) and indicates according to the programming of the Arduino Nano board (30), either with a sound, alarm, audible voice or light, so that the patient (3) aligns his foot, additionally it reacts to raising the knee (36) so as to achieve good rehabilitation.

[0077] The circuits (27 and 28) of the device (5) can additionally be programmed so that the gyroscope alerts the driver (37) (see figure 7) of a transport vehicle with an alarm when his head (6) passes the threshold of a certain angle, whether tilting or turning, thus preventing him from falling asleep and causing an accident.

[0078] The system electronics comprise:

[0079] - MPU6050 gyro module (29)

[0080] - Bluetooth Wireless Module HC05 (31)

[0081] - Arduino Nano, Micro AT Mega 328 type board (30)

[0082] - FC75 USB charging module (38)

[0083] - Power supply battery 2,599 mAh 3.7 volts (40)

[0084] In Figure 9, a perspective view of a housing (41) can be observed to house the corresponding electronics according to requirements.

[0085] In Figure 10, the emitter board (27) and the receiver board (28) and their components, previously mentioned, can be seen schematically.
