Book Description
Stroke is a serious medical condition that often involves the death of the recipient. Although fatality is not definite, many stroke survivors tend to suffer the inconvenience of losing the functions of their limbs. Studies have shown that task oriented recursive movements can help stroke affected individuals to recover mobility of their damaged limbs. Manual therapy used to make stroke patients recover movement is successful, but robot-assisted therapy excels in many fields including accuracy and repeatability. Many currently available rehabilitation robots share common disaffections of being overly complex, costly and voluminous. A compact and inexpensive upper limb rehabilitation device was therefore developed in this study to provide stroke therapy to the general public. For the developed rehabilitation device, DC motors were selected as the actuator of the system for their high power and torque capabilities. PID controller was implemented for control of motor position, while trapezoidal velocity profile was employed for motor speed control. Sensors such as accelerometers, encoders and strain gauges were utilized to provide detailed data of the rehabilitator and various onboard components. Safety was enforced with both boundary walls and limit switches, as well as software controlled emergency stop. Microcontrollers were used as the system controllers, with a main Master microcontroller handling system operations while two Slave microcontrollers were dedicated to the control of the DC motors. A GUI was developed for the PC to allow interfacing and control of the rehabilitator. The program permits tuning of various robot parameters, and offers different therapy modes as well as an interactive game. The upper limb rehabilitation device developed has followed the set specifications and achieved the desired performance. The rehabilitator is capable of producing successful trajectory runs with a maximum error of 5 mm at low speed (1.88 rad/s) and 6 mm at high speed (3.77 rad/s) under no load condition. Similar results were also obtained maximum deviation of 4 mm at low speed and 6 mm at high speed under arm loaded setup.

Book Description
Current upper limb rehabilitation for stroke patients is based on a conventional physical therapy supervised by therapists. The most of the robot-based rehabilitation is developing under a bulky machine which is not suitable for home use. High rehabilitation fees and inconvenience in use lead patients from ordinary home to miss the suitable time in rehabilitation. This research explores an end-effector device which is light and suitable for the home environment. By balancing the contradiction of device function achievement and ordinary home use, this 3 DOF rehabilitation device is the appropriate choice for the current situation. Different with other low-cost devices in the markets, it can provide an assistant force in the recovery process. It makes severe patients can take passive rehabilitation exercises under totally device leading and minor stroke patients take active rehabilitation exercises by their own intention. After studying the upper limb motions in normal physical actions, the joint movement in those motions is discussed with details. Some effective recovery tasks are achieved by analyzing the conventional physical exercise for stroke. The research of human-machine interaction is conducted to reveal a method in interaction tasks design. The new version of device is designed and has the potential for better performance in structural stability, but the development in software and testing of new strategies are implemented on the old version because of funding issue. Different recovery patterns with different control strategies are exploited and compared in this article to select the appropriate training model in upper limb rehabilitation. The approach of novel human-machine interface, control strategy and upper limb recovery strategy built in this research offers a potential inspiration in upper limb rehabilitation device development.

Book Description
The objective of this thesis is to discuss the use of rehabilitation robotics in non-specialized settings, identify technical, social, and economic bottlenecks, make predictions about technological trends developing from 2012 to 2025, and present findings and investment opportunities for private corporations, stakeholders, and governments in order to assist them in making funding decisions. Epidemiological and demographical changes like aging are leading to a growing service-robot market (rehabilitation devices are part of this domain), which will continue to grow over the next twenty years. The production of rehabilitation devices will increase with the overall market sector. Clinical trials have proven that robotics systems can be used effectively for upper-limb rehabilitation. Supporting the growth of the rehabilitation robotics industry (especially those rehabilitation robots designed for use outside of rehabilitation clinics) could be beneficial to post-stroke subjects in terms of access, intensity, and cost efficiency. The findings of this thesis show that many of the existing rehabilitation devices which help stroke victims regain upper-limb motion are ineffective in nonspecialized settings (like the patient's home) and furthermore, many promising robots have yet to be commercialized. The findings also reveal a gap between the five important stakeholder groups (patients, partners or relatives, paid carers, therapists, and health and social care budget holders) and their needs, such as trade-offs between therapists, systems, and patients. Current rehabilitation devices which are widely accepted for clinical use like the ARMin (Armeo Power of Hocoma) amongst others, are discussed in this paper. Observations and suggestions for a more user-centered design are made for currently available devices, which often fail to provide a 100% ergonomic solution. The research shows that there is a need for user-driven research, outstandi.

Book Description
The purpose of this project was to design and evaluate a mechanical training device for the upper limb rehabilitation of stroke survivors. The importance of this issue is widely acknowledged, particularly given the rising number of stroke patients presenting with rehabilitation challenges. Therefore a feasible and clinically effective solution for rehabilitation of the upper limb is needed. A critical review of literature examined theory and concepts pertaining to complications of general, stroke, rehabilitation of the upper limb, device design, testing processes and benefits and challenges of existing devices. A three-phased approach was adopted towards the design and evaluation of the device named CataPULT; Development of device specification, Production of the device, and Testing of the device on a single healthy subject. Testing involved three assessments; Isolated range of motion; Elastics load capacity; and Functional movement. CataPULT demonstrated the capacity for engaging three modes of operation; between 'Elastic', 'Free', and 'Locked' modes which are interchangeable within clinical environments with appropriate tools. Findings highlighted that CataPULT has the potential to support the arm and provide assisted movement through a functional range of motion to facilitate upper limb rehabilitation following stroke. The elastics enhanced device function by applying forces over the mechanical joints to assist in joint motion, thus reducing the energy required to perform functional activities. Other advantages of the CataPULT identified in comparison with alternative technologies such as robotic devices were that the device involves a cost effective manufacturing process, components are readily available and inexpensive to replace, and the device is extremely portable at home and in the clinical environment. With further development of the device, additional benefits may be possible and to this end, further opportunities for research have been identified.
