Description

“MULTIFUNCTIONAL REHABILITATION APPARATUS”TECHNICAL FIELD

[0001] The present invention relates to the field of rehabilitation technology, specifically to a multi-functional rehabilitation apparatus designed for therapeutic exercises and recovery training for individuals recovering from neurological impairments. The apparatus addresses rehabilitation needs arising from neurological, orthopedic, post-surgical, and mobility-related conditions by enabling controlled, safe, and adaptive movement support for various body parts in clinical or home environments.BACKGROUND

[0002] Rehabilitation is a critical aspect of recovery from a neurological impairment (such as stroke or spinal cord injuries, orthopedic injuries involving joints or muscles, post-surgical recovery, and age-related mobility challenges). The goal of rehabilitation is to restore function, independence, and quality of life. Traditional rehabilitation methods often rely on physical therapists to guide patients through exercises, which may be limited by the therapist's availability, the patient's location, and the overall accessibility of rehabilitation facilities. Additionally, many existing rehabilitation devices are stationary, bulky, and not easily transportable, making them less practical for home use or various therapeutic settings.

[0003] Existing robotic rehabilitation solutions are predominantly sold to hospitals, making them financially prohibitive for many patients seeking home-based rehabilitation options. While a few systems are designed to accommodate either upper or lower-limbrehabilitation, they remain confined to clinical environments, limiting access for patients who need ongoing therapy in the comfort of their homes.

[0004] Conventionally, many modern rehabilitation systems are present in the market that simulate daily activities and employ sensors to track usage, providing mechanical feedback through rehabilitation robots. Additionally, some systems feature adjustable tables with video tracking and grasping force sensors, integrating gaming elements to enhance patient engagement. Other devices utilize a matrix of sensors to monitor limb movements, enabling a quantitative assessment of progress. While these innovations represent significant strides forward, they often still lack the versatility, portability, and comprehensive safety features needed for a more adaptable rehabilitation experience.

[0005] Recent advancements in technology have emphasized the importance of patient engagement and tailored rehabilitation programs. However, available devices do not adequately integrate real-time feedback mechanisms or adaptable support that may cater to the diverse needs of individual patients. This gap in the market highlights a need for more versatile, rehabilitation devices that allow for customizable exercises while ensuring patient safety and engagement

[0006] For example, U.S. patent 11833689 B2 relates to a rehabilitation apparatus and method for use of the apparatus by a user or patient. The rehabilitation apparatus is provided that transitions between a collapsed state for easy mobility and an open state for user operation. The device houses the rehabilitation robot within a compartment formed by movable housing portions. A mast assembly creates an access gap for the userduring operation and collapses after use to close the compartment, enabling compact storage and transport.

[0007] Another example, U.S. patent 20200368574 Al, discloses a system, method and apparatus for rehabilitation and exercise with multi-configurable accessories. The exercise and rehabilitation apparatus comprises a frame on a base with an arm pivotally attached to its top. The arm moves between retracted and extended positions, while handles at its distal end provide an additional degree of freedom for user-controlled exercise and rehabilitation.

[0008] None of the prior art discloses a detachable at least one arm and a plurality of sensors that are capable of monitoring a patient's weight and triggering an alarm in the event of a sudden pressure increase.

[0009] In light of the above-stated discussion, there is a need for a new and improved multi-functional rehabilitation apparatus with a compact structure, allowing it to be easily used in various rehabilitation environments, including homes, clinics, and hospitals, ensuring that patients have access to necessary therapy regardless of their location.OBJECTIVES OF THE DISCLOSURE

[0010] A primary objective of the present disclosure is to provide a multi-functional rehabilitation apparatus with a central base featuring either adjustable legs and wheels for ease of movement and stability or a stable base with non-adjusting legs, thereby enabling deployment and stable operation in a variety of settings, such as hospitals or home environments.

[0011] Another objective of the present disclosure is to provide the multi-functional rehabilitation apparatus that delivers an interactive and engaging exercise experience by integrating gamified or virtual-reality-based feedback systems.

[0012] Another objective of the present disclosure is to provide the multi-functional rehabilitation apparatus that ensures secure attachment of a patient’s body part with the apparatus to promote safe and effective rehabilitation exercises.

[0013] Another objective of the present disclosure is to provide the multi-functional rehabilitation apparatus that integrates with sensors to track and monitor various patient metrics for real-time data collection and feedback to healthcare providers or caregivers.

[0014] Yet, another objective of this invention is to provide compact, lightweight device that can be easily transported and set up, making it suitable for use in both clinical and home environments, enhancing accessibility to rehabilitation technology.SUMMARY OF THE DISCLOSURE

Specifically, the apparatus 100 allows the at least one arm 112 to approach the patient’s legs from the front, left, or right side, enabling targeted support for both lower and upper limb exercises. The plurality of sensors, including proximity and pressure sensors, continuously monitor the position and movement of the patient’s legs relative to the at least one arm 112. This multi-directional support and real-time adaptive feedback allows the patient to perform a wide variety of rehabilitation exercises, such as step lifting, lateral leg movement, or forward extension, while maintaining safety and enhancing overall confidence during treadmill-based therapy.

[0086] Fig 3 illustrates an image representation of the usage of the multi-functional rehabilitation apparatus 100, according to another exemplary embodiment of the present invention. The apparatus 100 also comprises the foldable supporting element 302 to support the patient's body while facilitating the range of rehabilitation exercises. This foldable supporting element 302 is movable in nature. It may easily move either in the upward direction or the downward direction according to the patient’s need.

[0087] In some implementations, the foldable supporting element 302 is a U- shaped structure but it may be customized in any shape and size according to the patients’ needs.

[0088] Now referring to Fig 3A, the apparatus 100 is shown configured for patient’s hand and forearm rehabilitation exercise. In this configuration, the at least one holding element 202 of the apparatus 100 is attached to the patient’s forearm, enabling support and stabilization while performing various rehabilitation exercises, thereby ensuring precise alignment and safe movement of the limb.

[0089] Now referring to Fig 3B shows the usage of the multi-functional rehabilitation apparatus 100 for patient’s leg rehabilitation exercise. In this configuration, the at least one holding element 202 of the apparatus 100 supports the patient’s calf region, enabling the performance of various rehabilitation exercises. In another embodiment of this configuration the at least one holding element 202 of the apparatus 100 supports the lower portion of the patient's leg, enabling the performance of various rehabilitation exercises.

[0090] Now referring to Fig 3C demonstrates the use of the multi-functional rehabilitation apparatus 100 for a patient's leg rehabilitation exercises in a rehabilitationsetting, along with a treadmill. In this configuration, the at least one holding element 202 of the apparatus 100 supports a lower portion of any of the patient's leg, enabling the performance of various rehabilitation exercises on the treadmill. In another embodiment of this configuration the at least one holding element 202 of the multi-functional rehabilitation apparatus 100 supports the upper and lower portion of the patient's leg simultaneously, enabling the performance of various rehabilitation exercises. Further, the foldable supporting element 302 are provided with the multi-functional rehabilitation apparatus 100 to support the patient's body and monitor the patient's weight and trigger the alarm in case of sudden pressure increase, while facilitating the range of rehabilitation exercises.

[0091] Further, the alarms are generated using an alerting module (not shown in the pictures) that generates an audible alarm using a loudspeaker or a siren. Further, the processor (not shown in the images) may also send a notification to the caregiver about the patient's weight, making the apparatus 100 valuable for remote monitoring of the patient without needing to be present in real time. Furthermore, the notification may also be sent on a regular basis to monitor any slight weight increase, allowing for prompt response before any issues arise.

[0092] In accordance with another exemplary embodiment of the present invention, the at least one arm 112 of the multi-functional rehabilitation apparatus 100 may be dynamically repositioned to provide diagonal or rotational support to the patient’s legs during treadmill exercises. For lateral leg movements, two motors associated with the at least one arm 112 are actuated to enable controlled side-to-side motion, while forcomprehensive gait training, all three motors are engaged to allow complex trajectories and angular adjustments. The proximity and pressure sensors continuously track both the patient’s movement and the arm’s orientation, ensuring precise alignment and safe interaction. In case the patient’s leg deviates from the intended path, the processor adjusts the arm’s trajectory and exerts corrective forces to gently guide the limb back into position, providing a responsive and adaptive rehabilitation environment.

[0093] In accordance with an above embodiment of the present invention, the gait training involves guiding the patient’s limb along a controlled curved or circular trajectory to simulate natural variations in walking patterns. The at least one arm 112 of the rehabilitation apparatus 100 may be dynamically repositioned to provide rotational support, while pivot points and holding elements ensure proper alignment and contact with the limb. The plurality of sensors continuously monitors the limb’s position and movement, allowing the processor to make real-time adjustments. In case of deviation from the intended rotational path, corrective forces are applied to gently guide the limb back into position.

[0094] In one embodiment, the foldable supporting element 302 may be deployed to stabilize the patient’s torso or lower body while performing complex treadmill exercises. The plurality of sensors configured with the foldable supporting element 302 detect sudden shifts in weight or imbalance and communicate this information to the processor. The processor then modulates the arm’s movement speed and holding force in real time, allowing the patient to safely practice forward, lateral, or diagonal stepping motions without risk of falling or injury.

[0095] In addition, the apparatus 100 is configured to accommodate multi-limb rehabilitation simultaneously. For example, while the at least one arm 112 provides support to the right leg, an additional arm may engage the left leg, enabling coordinated bilateral exercises. The processor continuously analyzes sensor data from all active arms and supporting elements, adjusting exerted forces and movement patterns to ensure synchronized, safe, and effective rehabilitation. The multi-directional support combined with real-time adaptive feedback enhances the patient’s ability to regain strength, balance, and coordination during treadmill-assisted therapy, providing a customizable and highly interactive rehabilitation experience.

[0096] In accordance with another exemplary embodiment of the present invention, the rehabilitation apparatus 100 is integrated with a gamified and virtual reality (VR)- assisted training module to enhance patient engagement and exercise effectiveness. The apparatus 100 includes the plurality of sensors comprising motion, pressure, and proximity sensors that continuously monitor the patient’s limb position, movement accuracy, and applied force during rehabilitation exercises. The captured data is transmitted to the connected processor or user device 402 that renders real-time virtual feedback through an AR / VR interface, such as a headset or display screen. As the patient performs exercises, the processor translates their physical movements into interactive gameplay, such as reaching, lifting, or balancing tasks within a virtual environment, thereby promoting active participation and coordination improvement.

[0097] In one implementation, the gamified interface may present progressive exercise levels, visual targets, or motion-based challenges, each calibrated according tothe patient’s recovery stage and therapeutic requirements. The processor dynamically adjusts the resistance, arm movement range, or response sensitivity of the apparatus based on the patient’s performance metrics. This not only helps in tracking progress quantitatively but also encourages longer and more consistent therapy sessions by transforming routine rehabilitation exercises into an enjoyable, immersive experience. Such integration of interactive technology ensures that rehabilitation remains motivating, personalized, and effective across diverse user groups, including those recovering from neurological or orthopedic conditions.

[0098] Figure 4 illustrates an exemplary configuration of the multi-functional rehabilitation apparatus 100 in accordance with an embodiment of the present invention. In this embodiment, the at least one pillar 108 is shown as detachably mounted and installed directly onto a (stationary) support structure 404 (such as a wall or fixed frame), eliminating the need for the central base 102 or the plurality of wheels 106 for stability or mobility. The ball spline shaft 110 is mounted parallel to the pillar 108, and the at least one arm 112 is attached to the shaft, allowing vertical and angular movement independently of the central base 102. The at least one holding element 202 is positioned at the distal end of the arm 112, ready to engage with the patient’s limb during rehabilitation exercises.

[0099] In one embodiment, this configuration allows the apparatus 100 to be deployed in fixed spaces such as homes, clinics or rehabilitation centers where floor space may be limited, while still providing the full range of movement, sensor-based monitoring, and patient support functions. The detachable at least one pillar 108 ensuresmodularity, enabling quick installation, adjustment, or removal as required for different therapy setups or patient-specific exercises.

[0100] In another embodiment, the apparatus 100 may further include additional interchangeable attachments configured at the distal end of the at least one arm 112 for performing targeted rehabilitation exercises for different body parts. These attachments may include a hand rehabilitation module, a foot rehabilitation module, or other specialized gripping or supporting components, each designed to assist a particular range of motion or muscle group during therapy.

[0101] In one embodiment, the apparatus 100 may also incorporate one or more Z- axis movement mechanisms, including but not limited to ball screw drives, telescopic linear actuators, or gravity-assisted load-balancing assemblies, to facilitate smooth, controlled, and precise vertical motion of the at least one arm 112 or at least one holding element 202. These mechanisms allow the apparatus 100 to adapt to varying loads and user requirements while maintaining high positional accuracy and safety during operation.

[0102] In yet another embodiment, the apparatus 100 may include at least one motor from the plurality of motors 116 that is coupled at the distal end of the at least one arm 112. The at least one motor may be configured to provide rotational or translational motion along a different axis, enabling fine-tuned control or actuation of an attached accessory, such as a therapeutic tool, sensor module, or interactive feedback unit. This configuration enhances the versatility of the apparatus 100 by allowing multi-axismovement and adaptive operation based on the type of rehabilitation exercise or patientspecific requirement.

[0103] In accordance with an advantageous embodiment of the present invention, the multi-functional rehabilitation apparatus 100 is capable of assisting the patient in achieving a complete range of motion (ROM) at the shoulder, elbow, hip, and knee joints, thereby facilitating comprehensive rehabilitation exercises. Further, the apparatus 100 is designed to be usable in a home environment with minimal intervention from caregivers. Caregiver assistance is required only initially for system setup, during the gait training mode if the patient requires support, and at the conclusion of each rehabilitation session.

[0104] In accordance with another advantageous embodiment of the present invention, the design of the apparatus 100 is intended to maintain a compact footprint while effectively managing the forces produced by the patient’s arms and legs during rehabilitation exercises. This ensures the apparatus 100 remains unobtrusive in a home setting. Further, the apparatus 100 is engineered to withstand the collapse of the patient while performing the gait training. It assists the patient in weight shifting and movement of the affected limb at the hip and knee, thereby promoting safe and effective rehabilitation.

[0105] In accordance with another advantageous embodiment of the present invention, the apparatus 100 is capable of assisting the patient in executing Sit-to-Stand (STS) movements, thereby enhancing functional mobility and independence. Furthermore, this apparatus 100 provides stroke patients with the opportunity to receivehigh-frequency rehabilitation services in the comfort of their own homes, maximizing accessibility and convenience.

[0106] In accordance with another embodiment of the present invention, the apparatus 100 may also be deployed in hospitals and rehabilitation centers, addressing the continuous need for rehabilitation services in these environments. Further, this embodiment illustrates the capabilities and innovative design features of the apparatus 100, emphasizing its utility in both home and clinical settings for comprehensive stroke rehabilitation.
