There are several elegant solution has been established for the initial design of this APK where the device can be fit into any type of chair, thinner belts for leg positioning, hanging remote control, stack up LCD and keypad, retractable knee placement and worm gear to increase the torque. In addition, the device will allow the user to set the speed of movement and the timing for the exercise. The device has manual and auto mode for the user feasibility to lift up and lift down the leg based on their desire. It also consists of muscle and motion sensor to detect the movement of user's muscle and the knee. These sensors will trigger and send signal to deactivate the motor if the user is able to move their leg and vice versa. Graphical User Interface (GUI) will be generated to monitor the patient's recovery by the physiotherapist via Universal Serial Bus (USB) port.
Design of Automated Physiotherapy Device for Knee Rehabilitation (APK) Using TRIZ
Automated Physiotherapy device for knee rehabilitation (APK) is an affordable, portable and weightless device for knee rehabilitation with a good performance in order to help the user to do the physiotherapy device. The device allows different size people to use it. APK allows the user to set the setting the time and speed. Besides that, the user can use either manual mode or auto mode to do the exercise. If manual mode is select, the user can select either the up option to lift up the leg and down option to lift down the leg. Whereas for auto mode, if the user able to move their leg, muscle sensor and motion sensor will be detected therefore the device will work intelligently by not triggering the motor if vice versa happens motor will be triggered to help the user to lift up and lift down the leg. There is also a Universal Serial Bus (USB) where the saved data can be retrieved by the physiotherapist to check on the patient’s recovery.

Rehabilitation following knee injury or surgery is critical for recovery of function and independence. However, patient non-adherence remains a significant barrier to success. Remote rehabilitation using mobile health (mHealth) technologies have potential for improving adherence to and execution of home exercise. We developed a remote rehabilitation management system combining two wireless inertial measurement units (IMUs) with an interactive mobile application and a web-based clinician portal (interACTION). However, in order to translate interACTION into the clinical setting, it was first necessary to verify the efficacy of measuring knee motion during rehabilitation exercises for physical therapy and determine if visual feedback significantly improves the participant’s ability to perform the exercises correctly. Therefore, the aim of this study was to verify the accuracy of the IMU-based knee angle measurement system during three common physical therapy exercises, quantify the eff...
Simplifying Tele-rehabilitation Devices for Their Practical Use in Non-clinical Environments
Lecture Notes in Computer Science, 2015
The lack of success of tele-monitoring systems in non-clinical environments is mainly due to the difficulty experienced by common users to deal with them. In particular, for achieving a correct operation, the user is required to take care of a number of annoying details, such as wearing them correctly, putting them in operation, using them in a proper way, and transferring the acquired data to the medical center. In spite of the many technological advances concerning miniaturization, energy consumption reduction, and the availability of mobile devices, many things are still missing to make these technologies simple enough to be really usable by a broad population, and in particular by elderly people. To bridge this gap between users and devices, a smart software layer could automatically manage configuration, calibration, and data transfer without requiring the intervention of a formal caregiver. This paper describes the key features that should be implemented to simplify the needed initial calibration phase of sensing systems and to support the patient with a multimodal feedback throughout the execution of the exercises. A simple mobile application is also presented as a demonstrator of the advantages of the proposed solution.
Smart portable rehabilitation devices
Journal of neuroengineering and rehabilitation, 2005
The majority of current portable orthotic devices and rehabilitative braces provide stability, apply precise pressure, or help maintain alignment of the joints with out the capability for real time monitoring of the patient's motions and forces and without the ability for real time adjustments of the applied forces and motions. Improved technology has allowed for advancements where these devices can be designed to apply a form of tension to resist motion of the joint. These devices induce quicker recovery and are more effective at restoring proper biomechanics and improving muscle function. However, their shortcoming is in their inability to be adjusted in real-time, which is the most ideal form of a device for rehabilitation. This introduces a second class of devices beyond passive orthotics. It is comprised of "active" or powered devices, and although more complicated in design, they are definitely the most versatile. An active or powered orthotic, usually employs so...

Physical therapy helps patients during their rehabilitation programme after orthopaedic post-operative interventions or in case of musculoskeletal injuries. For a full recovery and a minimisation of the risk of complications, the prescribed in-clinical therapy sessions must be supplemented by independent home training. The purpose of this paper is to present the emerging technologies used for monitoring ortophedic movements and to introduce an innovative telerehabilitation-as-aservice solution, called re.flex, which consists of two IMU (Inertial Measurement Unit) motion tracking sensors and a mobile application The therapist makes use of standardised digitised physical exercises that are carefully chosen so as to create, by selection, a custom designed training program that will meet the needs of each patient. The feedback provided by the sensors enables the therapist to a) monitor the patients' compliance with the training program in a transparent manner, b) keep track of the documentation related to the recovery progress through data-collection during in-clinical and in-home exercise-based rehabilitation c) customize the training program. The real-time 3D smartphone animations and the direct visual, audio and haptic feedback from the sensors assist patients in performing the rehabilitation exercises assigned to them. The abovementioned application allows the patients to visualise their injured limb on their smartphone or tablet in an innovative 3D-360° manner, thereby reducing their fear of making mistakes during the recovery process and offering them constant security. The study evaluates the effects of this kind of approach for a group of 30 participants and the results recorded are in favour of the patients recovering with re.flex.

International Journal of Scientific Research in Computer Science, Engineering and Information Technology, 2020
The monitoring system has been developed for serious cases of orthopedic injury and for the health of older people's lifestyles. It is designed for testing and discussion purposes, and the functionality was the most significant as opposed to the form factor. While significant, other aspects, such as defense, maintenance and economies of scale, were beyond our reach. This is important if the device continues to be used but is not enough for our testing. Orthopedic rehabilitation health monitoring at Home is Interconnecting devices and facilities that reduce human interference in order to live a healthier life. Acceleration readings are given in this project by using accelerometers for various axes x,y,z. The signals obtained by measuring adjustments in the movement of the two accelerometers mounted one on above knee and other on below the knee,either sides to knee joint of the person. Any movements in the joints will change in the accelerometers are mounted which makes the accelerometers to generate the output voltage with respect to the variation in gravity. In addition, along with heartbeat, temperature, alcohol concentration sensor output is generated voltage is fed as inputs to the microcontroller. Further the microcontroller will process this information to delivers output that is transmitted via Bluetooth on a mobile Android based device. The android app transforms incoming messages to report in detail information and alert to physician and caretaker.
New technologies used in the rehabilitation of knee pathologies
Health, Sports & Rehabilitation Medicine, 2023
Background. Research into human movement dysfunction is receiving increasing attention as the proportion of older adults and the number of obese people in the world's population continues to rise. Compared to the other joints in the lower limb, the knee joint is very delicate and susceptible to injury. Knee deficits are a prevalent physical ailment that substantially influences the day-today functionality and emotional welfare of those who suffer from them. Supporting the body weight, helping maintain lower limb balance, and absorbing shock while the body is in motion are the primary factors contributing to these deficits. Movement biomechanics is an essential subfield of biomechanics that investigates how bones, muscles, ligaments, and tendons coordinate with one another throughout different types of human movement. Aims. The purpose of this review is to devise and investigate novel approaches to the use of mobile devices in knee rehabilitation. This research investigates how mobile devices like smartphones and tablets are used in rehabilitation. Our primary emphasis will be on mobile applications that provide individualized workouts, continuous monitoring, and immediate feedback to patients. Conclusions. Undoubtedly, the technology will continue to develop and grow over time and be integrated with many other electronic health systems and devices. As a direct consequence of this advancement, physiotherapists will have more opportunities to assist in designing and developing exoskeletons that may be used throughout rehabilitation.
