Description

1 TARIFF MEASUREMENT OF SYNCHRONIZED LOAD SHARING RATIO BETWEEN CANE AND PROSTHESIS ADAPTIVE INTELLIGENT REHABILITATION SYSTEM PROVIDING Technological Field: The invention relates to the equalization of cane and prosthesis loads in lower extremity amputation rehabilitation. real-time measurement, wireless monitoring, and load sharing ratio for the user. It relates to a medical rehabilitation system that provides feedback through. 10 State of the Art: The process of transitioning to prosthetic limb use in individuals who have undergone lower extremity amputation, a process completed only by mechanically fitting the prosthesis to the patient 15 No. The user must learn to safely transfer weight to the prosthesis, cane, or gradual reduction of dependence on similar walking aids and walking It needs to bring the pattern into balance. However, in current rehabilitation practices... This load transfer is often based on the physiotherapist's observational assessment, the patient's This is followed up based on the patient's statement or the general clinical assessment during the session. 20 This situation is particularly relevant considering the actual amount of load transferred to the prosthesis and the dependence on the cane. This makes it difficult to determine its level objectively. In current technology, force platforms and pressure measurement devices are used in rehabilitation centers. These systems or gait analysis laboratories can be used. These systems are specific to 25 Although it provides a certain amount of numerical data, it is generally limited to clinical settings, costly, and not portable. These are structures that are difficult to integrate consistently into low-level and daily rehabilitation sessions. Furthermore, these types of systems often resemble a cane used by a patient in real-life situations. It is not possible to evaluate the use of the prosthesis and the loading of the prosthesis together. Therefore, in the clinic The measurement data obtained shows how the user transmits load in the home or in daily life. 30 It does not reflect the situation accurately. 2 Some known solutions involve load sensors placed on the cane to monitor the user. The force applied to the cane can be measured. These types of smart canes measure the load on the cane. While useful in providing information about, the load transferred to the prosthesis It does not allow for direct measurement. The user putting less weight on the cane is always important. This does not mean that the prosthesis is transferring sufficient and correct load. Therefore, only a cane 5 Systems that focus on the burden of prosthetics are an incomplete assessment in terms of prosthetic rehabilitation. It reveals. One of the major problems encountered in current practices is canes and prostheses. The loads on either side are not evaluated together within the same time window. Walking 10 During this process, the load transfer changes dynamically, and the user remains within the same step cycle. Knowing how much load is placed on the cane and how much on the prosthesis is clinically important. Data obtained from canes and prostheses, separately or at different times, regarding load This may not be enough to correctly interpret the shared information. This is especially true in this situation. 15 erroneous or delayed clinical assessments in graded prosthesis loading training This is the reason. In conclusion, the current technique measures cane load, prosthesis load, or clinical load. Although various systems exist that perform load analysis in an environment, these systems do not analyze the loads of canes and prostheses. simultaneously linking and directly providing the user with a load-sharing ratio of 20 It is insufficient in terms of presenting to a physiotherapist. Therefore, prosthetics load transfer in rehabilitation should be objective, instantaneous, customizable, and clinically decisive. We need integrated systems that enable monitoring in a way that is suitable for providing information. It is heard. Description of the invention: The primary aim of the invention is to improve the use of canes and prostheses in individuals undergoing prosthetic rehabilitation. The aim is to ensure that the transmitted cargo is tracked objectively, simultaneously, and in an understandable manner. thus, only observation-based assessment is performed during the rehabilitation process. 30 instead, how dependent the user is on the cane and the extent of the load on the prosthesis The amount of prosthetic load it can transfer can be determined numerically. Thus, insufficient prosthetic load, 3 Overloading the cane, unsteady walking habits, sudden weight transfer, and falls. Problems such as the late detection of risks can be identified earlier and more reliably. It will be possible. One of the key advantages of the invention is that the loads on the cane and prosthesis sides are distributed separately at 5 No, they are evaluated together. Cane load sensor module and prosthesis load sensor. Data from the module is synchronized to provide the user with real load sharing. This is presented as a percentage. This structure is quite critical in prosthetic rehabilitation. This facilitates the monitoring of the gradual load transfer and allows the physiotherapist to understand the patient's condition. It provides an opportunity to assess progress more clearly. 10 The system facilitates the motor learning process by providing the user with real-time feedback. It supports LED indicator strip, haptic motor area, audible warning unit and mobile. Thanks to the screen, the user can see during the session whether they are applying the targeted load to the prosthesis. They will be able to understand it during the session. Thus, the erroneous load transfer will only be noticed at the end of the session. The user is not guided; they are directly guided during walking or balance exercises. The invention also contributes to the personalized implementation of rehabilitation. The user... prosthesis type, rehabilitation phase, and target load determined by the physiotherapist. The sharing ratio can be defined in the system. This allows for more protection in the early stages, 20 In later stages, a gradual approach is aimed at transferring more load to the prosthesis. The program is feasible. Another advantage of the invention is its use in both clinical sessions and home exercises. It is available. The load-sharing ratio via mobile screen is 25. This allows the information to be viewed even when the user is not with a physiotherapist. This helps them to do their exercises in a more controlled manner. This is especially true at home. It reduces data gaps in rehabilitation and ensures a safer process. It provides. In conclusion, the invention makes load transfer in prosthetic rehabilitation more visible and controlled. and makes it customizable. It provides the user with a secure payload transfer habit. 4 While providing benefits, it also gives the physiotherapist the opportunity to manage the treatment process with numerical data. In this respect, the invention supports the process of adapting to the use of prosthetics. integrated solutions that improve the quality of rehabilitation and provide practical contributions to clinical practice.

This structure allows them to receive tactile feedback without needing to look at it. vibration that will not distract the user, especially during gait training. It allows for the issuance of warnings via this method. For example, the load that needs to be transferred to the prosthesis is 15. When the ratio falls below a certain level or excessive load is placed on the cane, the haptic motor region (5) can create a specific vibration pattern. The audible alert unit (6) is the element of the system that provides auditory feedback. Audible alert unit (6), off-target load transfer, session start, calibration completion, battery 20 It can be configured to notify the user of information such as alerts or connection status.

Non-slip. The sole (9) can be made of rubber or a similar high-friction material. Thus During rehabilitation, the risk of the user losing balance and the load are reduced. This ensures that the measurement is carried out more reliably. 5 On the prosthetic side of the invention, the prosthetic structure can be integrated into the user's existing prosthetic structure or There is a retrofittable prosthetic load-sensing device. This device; socket (10), pyramidal connection (11), prosthetic load sensor module (12), carrier shaft (13), 10 on the prosthetic structure consisting of ankle connection (14) and prosthetic foot (15) The prosthetic socket (10) is positioned so that the amputation area is connected to the prosthesis. It is the part that provides the connection between the prosthesis socket (10) and the sub-components of the prosthesis. Pyramidal connection (11) is located.
