More specifically, the device also integrates various therapeutic modes and exercise means to aid users in rehabilitation, muscle strengthening, and overall wellness, thus improving posture, aiding muscle recovery, and enhancing strength through personalized therapeutic and exercise solutions.

BACKGROUND OF THE INVENTION

[0002] Strengthening the hamstring and foot muscles is essential for improving mobility, stability, and overall lower limb function. Proper rehabilitation of these muscle groups enhances flexibility, reduces the risk of injuries, and promotes balanced muscle engagement during movement. Effective strengthening techniques contribute to better posture, improved athletic performance, and faster recovery from muscle strain or weakness. Ensuring targeted muscle activation and controlled resistance during rehabilitation allows for progressive strengthening, minimizing the risk of overexertion or improper technique. Addressing the specific needs of users through personalized therapeutic approaches enhances overall recovery outcomes, supporting long-term musculoskeletal health and functional independence.

[0003] Traditional methods for strengthening the hamstring and foot muscles often rely on basic exercises and manual techniques that require significant physical effort and consistency. These approaches present several drawbacks. For example, conventional methods lack the ability to provide targeted resistance or real-time feedback, making it difficult to ensure proper muscle activation and alignment. Furthermore, manual techniques do not account for individual differences in strength, flexibility, or rehabilitation needs, leading to ineffective or imbalanced muscle engagement. The absence of adaptive support and controlled progression increases the risk of strain or improper technique, limiting the overall effectiveness of rehabilitation. Additionally, traditional methods fail to provide a structured and personalized approach, which is essential for achieving consistent progress and optimal recovery. To enhance the efficiency and effectiveness of rehabilitation, adopting advanced solutions that offer real-time monitoring and adjustable resistance is crucial for promoting safe and targeted muscle strengthening.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a rehabilitation device for hamstring muscles and lower limbs strengthening that enable customized therapy and exercise programs that support better posture, accelerate muscle healing, and enhance strength, leading to an overall improvement in physical well-being.

[0022] Referring to Figure 1, a perspective view of a rehabilitation device for hamstring muscles and lower limbs strengthening comprising a seat unit 101 configured to support a user in a seated position, an elongated plate 102 attached with frontal portion of the seat unit 101 and attached with a footrest 103, an artificial intelligence-based imaging unit 104 installed on the seat unit 101, a set of hollow patches 105 are embedded over the plate 102, the patches 105 are integrated with a vibrating unit 106, a temperature-controlled air blower 107 is connected to the seat unit 101, a hologram projection unit 108 integrated with the seat unit 101, a speaker unit 109 is integrated with the seat unit 101, a pair of panels 110 with electromagnetic springs 111 are located with a free-end of each of the plate 102, the plate 102 further comprises a series of mechanical actuators 112, a ball-and-socket joint 113 is integrated between the seat unit 101 and each of the plate 102, lumbar support of the seat unit 101 is connected to the backrest via an extendable horizontal bar 114, multiple resistance bands 115 are attached with the plate 102 that are connected to the plate 102 via a motorized sliding unit 116.

[0023] The device disclosed herein comprising a seat unit 101 that is designed to provide support to the user in a seated position, ensuring comfort and stability. The backrest of the seat unit 101 is integrated with multiple hinges, which are strategically positioned to allow for the adjustment of the backrest’s angle. These hinges are specifically configured to permit the backrest to transition smoothly between a vertical position and a fully horizontal position, enabling the user to modify the seating posture as required.

[0024] The hinges mentioned above are preferably motorized hinges that involves the use of an electric motor to control the movement of the hinges and the connected component. The hinges provide the pivot point around which the movement occurs. The motor is the core component responsible for generating the rotational motion. It converts the electrical energy into mechanical energy, producing the necessary torque that drives the hinges. As the motor rotates, the motorized hinges tilts and adjust angle of the backrest between a vertical and a fully horizontal position.

[0025] The lumbar support of the seat unit 101 is integrally connected to the backrest through an extendable horizontal bar 114. This bar 114 is developed to automatically adjust its position in response to real-time feedback received from posture sensors embedded within the seat unit 101. The dynamic adjustment of the bar 114 ensures that the lumbar support maintains optimal alignment, specifically targeting improvements in the user’s pelvic posture. This automatic adjustment enhances the user’s comfort and posture while seated, aligning the pelvis appropriately to provide consistent support and reduce potential strain or discomfort.

[0026] The posture sensors integrated into the seat unit 101 use a combination of accelerometers, gyroscopes, and pressure sensors. The accelerometers measure the user’s body orientation by detecting the angle of tilt in multiple directions, while the gyroscopes track rotational movements to detect any shifts in posture. Pressure sensors monitor the distribution of force on different parts of the seat to detect whether the user is sitting evenly or if there is uneven pressure that suggests poor posture. This data is continuously sent to the microcontroller, which processes it in real-time. If the user’s posture deviates from the ideal alignment, corrective adjustments to the backrest angle or lumbar support are automatically triggered to ensure proper alignment and comfort.

[0027] The bar 114 is pneumatically actuated, wherein the pneumatic arrangement of the bar 114 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic bar 114, wherein the extension/retraction of the piston corresponds to the extension/retraction of the bar 114. The actuated compressor enables the extension of the bar 114, which automatically adjusts to improve pelvic alignment based on real-time feedback from posture sensors.

[0028] An elongated plate 102 is securely attached to the frontal portion of the seat unit 101 and is connected to a footrest 103 designed to support the lower limbs of the user during various exercise positions. This configuration ensures that the user's legs are properly positioned and supported, providing stability and comfort during the performance of exercises, thereby enhancing the overall efficacy of the device in facilitating therapeutic or exercise routines. The plate 102 and footrest 103 together work in unison to maintain correct posture and support the user's body, ensuring that the exercises are performed effectively and safely.

[0029] In between the seat unit 101 and each of the plate 102 a ball-and- socket joint 113 is integrated. The motorized ball and socket joint 113 mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The plate 102 is attached to the socket of the motorized ball and socket joint 113, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint 113. The motor responds by adjusting the ball and socket joint 113 and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the plate 102. As the ball and socket joint 113 move, it provides the necessary movement to the plate 102 for allowing the plate 102 angle to be modified in response to different foot positioning requirements during exercise.

[0030] A communication module is integrated with the microcontroller of the device, facilitating wireless communication between the microcontroller and a computing unit. This connection allows the user to input personal and medical information into a user profile, which is stored in an integrated database for reference. The communication module enables the transfer of data to and from the computing unit, ensuring that the user profile is continuously updated with relevant information. This allows for a more personalized experience, ensuring that the device adapt to the user's specific needs based on their personal and medical data.

[0031] The plate 102 further incorporates a plurality of mechanical actuators 112 designed to enable the customized positioning of legs according to the user's specific therapeutic requirements. These actuators 112 adjust the leg positioning dynamically, allowing for tailored support during exercises intended for hamstring strengthening. This mechanism ensures that the user's individual needs are addressed by adjusting the leg positions to provide optimal alignment and support, thus enhancing the effectiveness of therapeutic exercises aimed at improving hamstring strength.

[0032] The mechanical actuators 112 are triggered by commands from the microcontroller, which receives inputs from posture sensors embedded in the seat unit 101. Upon activation, the actuators 112 adjust the positioning of the legs by extending or retracting the connected components. The actuators 112 utilize motors or pneumatic arrangements to ensure precise leg adjustments according to the therapeutic needs of the user. This allows for customized leg positioning to enhance hamstring strengthening exercises. The actuators 112 work with real-time feedback from the sensors to achieve the desired leg angle or position based on the user’s requirements.

[0033] The seat unit 101 is installed with an artificial intelligence-based imaging unit 104 which track and assess user’s body positioning, focusing on pelvic tilt and knee alignment. The imaging unit 104 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the user’s body and the captured images are stored within memory of the imaging unit 104 in form of an optical data. The imaging unit 104 also comprises of the processor which processes the captured images.

[0034] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to track and assess user’s body positioning, focusing on pelvic tilt and knee alignment.

[0035] A set of hollow patches 105 are embedded over the plate 102, and these patches 105 are integrated with a vibrating unit 106. Upon activation, the vibrating unit 106 generates a reciprocating motion within the patches 105. This motion delivers therapeutic vibrations to the user’s muscles, promoting relaxation of tight muscles and improving blood circulation. The reciprocating action of the patches 105 enhances the therapeutic effect by targeting specific muscle groups and stimulating them to relieve stiffness. The vibrations also support better circulation, thereby providing comfort and aiding in muscle recovery.

[0036] The vibrating unit 106 embedded in the patches 105 operates by generating oscillatory motions upon activation. Electrical signals from the microcontroller power the unit, causing it to produce rapid, back-and-forth vibrations. These vibrations are transmitted through the hollow patches 105 to the user's muscles. The reciprocating motion targets specific muscle groups, inducing rhythmic pressure that stimulates blood flow and alleviates muscle stiffness. The continuous motion of the vibrating unit 106 helps to enhance muscle relaxation and improve overall circulation in the affected areas.

[0037] A plurality of electrode patches 105 are securely attached to the hollow patches 105, for enabling the delivery of electrical pulses directly to the user’s leg muscles. These pulses mimic the natural process of muscle contractions, stimulating the muscles to promote recovery. The electrical stimulation enhances circulation, reduces muscle tension, and accelerates the healing process by improving nutrient and oxygen flow to the muscle tissues. The patches 105 are positioned to target specific muscle groups, and their activity is adjustable to provide a customized treatment.

[0038] An Electromyography (EMG) sensor is strategically positioned on the hollow patches 105 to monitor and measure the electrical activity generated by the hamstring muscles. The sensor detects the electrical signals produced when muscles contract and transmit this information to the microcontroller for analysis. By monitoring these electrical signals, the sensor enables real-time tracking of muscle activity, facilitating precise adjustments to the therapeutic treatment. This data is utilized to assess muscle performance, detect fatigue, and optimize the intensity and duration of the electrical stimulation provided to the user’s hamstring muscles for enhanced recovery and performance.

[0039] The EMG sensor detects the electrical signals generated by muscle fibers during contraction. When a muscle is activated, it produces electrical impulses, which are picked up by electrodes on the sensor. These signals are then amplified and transmitted to the processing unit for analysis. The data is used to assess the level of muscle activation, allowing for real-time feedback and enabling adjustments to be made to the therapy or treatment plan based on the muscle’s response. This process ensures that the muscle receives adequate stimulation without overloading.

[0040] A temperature-controlled air blower 107 is connected to the seat unit 101, developed to provide both heating and cooling sensation to the user. The blower 107 delivers heated air for muscle relaxation and cool air to reduce inflammation. The temperature of the air is regulated to ensure it meets therapeutic requirements, providing the user with a customizable environment based on their specific needs. By adjusting the temperature of the air, the device ensures optimal comfort while promoting muscle relaxation and inflammation reduction, contributing to the overall therapeutic effect for the user during use.

[0041] The temperature-controlled air blower 107 utilizes a combination of heating and cooling elements, controlled by an integrated temperature sensor (e.g., thermistor). The blower 107 draws in ambient air, which is then either heated or cooled by the respective elements. The temperature sensor continuously measures the air temperature and adjusts the heating or cooling components accordingly to maintain the desired temperature. Once the temperature is regulated, the blower 107 directs the conditioned air towards the user. This air helps relax muscles when heated or reduces inflammation when cooled, providing a personalized therapeutic experience based on real-time temperature adjustments.

[0042] A pair of panels 110, each incorporating electromagnetic springs 111, are positioned at the free ends of the plate 102. The electromagnetic springs 111 are configured to modify their resistance based on the pressure applied by the user. This adjustment occurs as the pressure is detected through a pressure sensor integrated within each of the panels 110. As a result, the electromagnetic springs 111 dynamically respond to the user’s exertion by either increasing or decreasing their resistance, thereby providing customized support and resistance during exercises, which enhances the overall exercise experience and performance.

[0043] The pressure sensor detects applied force by the user on to the panel 110, the sensor's sensing element, typically a piezoelectric material or a strain gauge, deforms. This deformation alters the electrical properties of the sensor. The sensor converts the mechanical pressure into an electrical signal that correlates with the amount of pressure applied. This signal is then transmitted to the microcontroller, which processes the data to adjust the resistance of the electromagnetic springs 111 accordingly, providing dynamic resistance during exercises.

[0044] The electromagnetic springs 111 are a specialized type of springs 111 in which the magnetic field is produced by an electric current. When the current is passed through the springs 111, it creates a magnetic field around the springs 111 that energizes the springs 111 to adjust their resistance in response to pressure applied by user on to the panels 110, providing dynamic support and resistance during exercises.

[0045] A plurality of resistance bands 115 (preferably 2 to 6 in numbers) are affixed to the plate 102, wherein each band 115 is connected to the plate 102 through a motorized sliding unit 116. The motorized sliding unit 116 facilitates translation of the resistance bands 115 based on real-time user input, enabling the user to engage specific muscle groups during exercise. The resistance bands 115 are configured to offer customizable resistance, which is varied to accommodate the user's strength and fitness level. This arrangement allows the user to focus on strengthening targeted muscles such as the hamstrings, calves, and feet, thus promoting muscle growth and enhancing endurance throughout the exercise routine.

[0046] The sliding unit 116 consists of a pair of sliding rail fabricated with grooves in which the wheel of a slider is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in clockwise and anti-clockwise direction that aids in rotation of shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the slider results in translation of the resistance bands 115 for enabling the user to engage specific muscle groups during exercise.

[0047] The seat unit 101 is installed with a hologram projection unit 108 that project visual representation of an ideal posture or alignment. The hologram projection unit 108 disclosed herein, comprises of multiple lens. After getting the actuation command from the microcontroller, a light source integrated in the projection unit 108 emits various combination of lights toward the lens which is further portrayed to project visual representation of an ideal posture or alignment, guiding the user to maintain proper posture during use.

[0048] Simultaneously, users provided with an auditory alert through a speaker unit 109 that is integrated with the seat unit 101. The speaker unit 109 disclosed herein works by receiving signals from the microcontroller, converting them into sound waves through a diaphragm’s vibration, and producing audible sounds with the help of amplification and control circuitry in order to generates an auditory alert when user’s posture deviates from ideal alignment, prompting the user to adjust position and maintain optimal posture for therapeutic or exercise purposes.

[0049] The device includes a set of multiple therapeutic modes, such as recovery mode, posture mode, and strengthening mode. Each mode is designed to address specific therapeutic needs by utilizing a combination of heat, vibration, electrical stimulation, and resistance control. Recovery mode focuses on muscle relaxation and reducing inflammation, while posture mode aims to improve spinal alignment and posture. Strengthening mode provides resistance exercises to enhance muscle endurance and growth. The integration of these modes ensures a comprehensive approach to therapy, tailored to the user's individual requirements, promoting overall wellness and recovery.

[0050] In an embodiment of the present invention recovery mode promote muscle healing and alleviate pain. In this mode, the device begins by providing heat sensation, where the hollow patches 105 inflate to deliver soothing warmth to the user's legs and feet. Once heat sensation is completed, the vibration unit is directed, for providing a calming massage that helps release muscle tension and improves blood circulation, aiding in the recovery of sore or fatigued muscles. Following this, electrical muscle stimulation is applied to the hamstrings, calves, and feet, promoting muscle contractions and relaxations, thus accelerating recovery without requiring the user’s active participation. To further assist in recovery, the footrest 103 is adjusted to elevate the legs, enhancing circulation and reducing swelling and discomfort, particularly after extended sitting or strenuous physical activity.

[0051] In another embodiment of the present invention posture mode actively monitors the user’s alignment using built-in pressure sensors and EMG data. The device makes real-time adjustments to encourage proper posture, ensuring the user maintains ideal alignment throughout use, which reduces the risk of developing postural issues. When poor posture is detected, corrective movements are triggered. For instance, the chair might adjust the seat angle or elevate the lumbar support to address slouching, keeping the user in an ergonomically beneficial position that promotes spinal health.

[0052] The lumbar support, connected to the backrest via the horizontal bar 114 and motorized hinges, that adjusts automatically to offer additional support to the lower back. If the user’s posture deviates, the chair dynamically shifts to improve pelvic alignment and ensure comfort. The footrest 103 is also adjusted through hinges to ensure the user’s feet are flat on the floor, with their knees forming a 90-degree angle, promoting optimal posture. To further assist, the chair includes the hologram projection unit 108, distracting the user from constantly thinking about their posture. If misalignment is detected, the chair generates the alert through the speaker unit 109, prompting the user to correct their posture.

[0053] In another embodiment of the present invention strengthening mode enhance muscle strength, with a particular focus on the legs and feet. During exercises, the user places their feet into resistance bands 115 connected to sliding unit 116, exerting pressure against them, which targets the hamstrings, calves, and feet, ultimately promoting muscle growth and endurance. Resistance bands 115 installed over the sliding unit 116 offer adjustable resistance based on user input, allowing users to engage their muscles more effectively and enhance strength.

[0054] This mode is particularly beneficial for hamstring strengthening, as users can control the resistance during leg movements. The resistance bands 115 is adjusted by moving them closer to or farther from the user, modifying the level of difficulty. By varying the distance, users can increase or decrease the intensity of their workout, tailoring the resistance to their needs and progress. The footrest 103 in Strengthening Mode also allows users to exert pressure at different angles, targeting specific muscles in the feet and ankles. This customizability ensures that users perform effective strengthening exercises, improving foot and ankle strength while supporting overall leg health.

[0055] Moreover, a battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.
