Numerous people lose motor capabilities of their hands every year because of the Stroke. Rehabilitation robot was used to recover the movement ability based on the plasticity theory. Many robots have been proposed but most of them are either expensive or quite complicated.
This thesis presents an adjust wrist rehabilitation robot. The proposed design fully utilizes the three rotational motions to rehabilitate the human wrist. A multiobjective optimization problem was applied to increase both stiffness and dexterity of the robot.
The CAD model is constructed and the inverse kinematic, Jacobian matrix, stiffness, dexterity formulas are derived. The workspace atlas is generated. The optimization work is conducted and it proves quick, robust and easy-to-use by the results comparisons.
Lastly, a CAD model was developed and results were verified by animation video and FEA analysis.
[ARTICLE] VR-Assisted Physical Rehabilitation: Adapting to the Needs of Therapists and Patients – Full Text
…Virtual Reality technologies are slated to transform the practice of physical rehabilitation and the potential benefits have only started to be explored. We present in this paper a direct motion demonstration approach for allowing therapists to intuitively create and edit customized exercises and therapy programs that are responsive to the needs of their patients. We propose adaptive exercise models, motion processing algorithms, and delivery techniques designed to achieve exercises that effectively respond to physical limitations and recovery rates of individual patients.
Remote networked solutions are also presented for allowing therapists and patients to intuitively share their motions during real-time collaborative therapy sessions. Our solutions have been implemented as a low-cost portable system based on a Kinect sensor, and as a highend virtual reality system providing full-scale immersion. We analyze and discuss our methods and systems in light of feedback received from therapists…
REVIEW: Web-Based Intervention Programs for Depression: A Scoping Review and Evaluation – Full Text (HTML)
…Although depression is known to affect millions of people worldwide, individuals seeking aid from qualified health care professionals are faced with a number of barriers to treatment including a lack of treatment resources, limited number of qualified service providers, stigma associated with diagnosis and treatment, prolonged wait times, cost, and barriers to accessibility such as transportation and clinic locations. The delivery of depression interventions through the Internet may provide a practical solution to addressing some of these barriers.
The purpose of this scoping review was to answer the following questions: (1) What Web-delivered programs are currently available that offer an interactive treatment component for depression?, (2) What are the contents, accessibility, and usability of each identified program?, and (3) What tools, supports, and research evidence are available for each identified program?…
Stroke is the most common cause of homonymous hemianopia (HH) in adults, followed by trauma and tumors. Associated signs and symptoms, as well as visual field characteristics such as location and congruity, can help determine the location of the causative brain lesion.
HH can have a significant effect on quality of life, including problems with driving, reading, or navigation. This can result in decreased independence, inability to enjoy leisure activities, and injuries. Understanding these restrictions, as well as the management options, can aid in making the best use of remaining vision.
Treatment options include prismatic correction to expand the remaining visual field, compensatory training to improve visual search abilities, and vision restoration therapy to improve the vision itself. Spontaneous recovery can occur within the first months. However, because spontaneous recovery does not always occur, methods of reducing visual disability play an important role in the rehabilitation of patients with HH.
The diagnostic facilities in our clinic are subject to the guidelines set out by the German Association for Clinical Neurology and our doctors all hold the relevant qualifications.
Interdisciplinary diagnoses are carried out quickly and efficiently in cooperation with our partner institutions. The most important clinical disciplines are represented in our centre by a system of consultation. Our close network of cooperation partners ensures that, where necessary, patients are transferred smoothly to the relevant departments.
…Robotic devices, sensors and game technology are set to transform the lives of patients who need arm or hand rehabilitation following a stroke or another neurological injury.
The Royal Melbourne Hospital’s Hand Hub, a first of its kind in Australia, will provide dedicated intensive hand and arm therapy to patients who have restricted use of their upper limbs…
Do you still have difficulty using your arm after a stroke?
If you or a relative have suffered a stroke and still have problems using your arm, then you might be interested in this NHS service at The National Hospital for Neurology and Neurosurgery (NHNN), Queen Square.
The multidisciplinary service is run by Dr Nick Ward (Consultant Neurologist), Dr Diane Playford (Consultant Neurologist), Fran Brander (Clinical Specialist Physiotherapist), and Kate Kelly (Clinical Specialist Occupational Therapist) with expertise in assessing and treating upper limb problems.
In the clinic, we offer advice on the management of patients with neurological upper limb deficits secondary to central nervous system disease. We are particularly interested to see stroke survivors who might benefit from more intense treatment of upper limb deficits, especially early after stroke.

This online, interactive courseware for the study of neuroscience is provided by the Department of Neurobiology and Anatomy at The University of Texas Medical School at Houston. The project is being developed under the direction of the Department Chair and Editor, John H. Byrne.
…“Instead of labour-intensive rehabilitation, all instructions and exercises are directed and supported by the computer-assisted robotics, and the therapist is therefore able to play a greater mentoring role,”…
