A caster walker is a supporting frame with casters and wheels under its legs. This tool is regularly utilized as a life support tool or a walking rehabilitation tool in hospitals, nursing homes and individual residences. This device easily moves thanks to its wheels and casters. However falling accidents often happen when it moves without users. The falling accident is very serious problem and one...
We have proposed a leg-shaped haptic simulator (Leg-Robot) that provides an environment for young physical therapist to learn rehabilitation techniques or diagnosis techniques with haptic information which mimics a real patient with abnormal motor function, for example, stroke or spinal cord injury. In previous studies, we also proposed a control method to develop a clonus-like movement for the Leg-Robot...
In this project, we have developed virtual haptic simulators that can simulate several kinds of abnormal movements and haptics of the disabled people. In the previous report, we proposed a leg-shaped robot (Leg-Robot) with a Compact MR Fluid Clutch (CMRFC) to establish highly safe human-machine co-existent system, and control methods to realize several kinds of abnormal symptoms. In this paper, we...
Recently the needs for medical rehabilitation support systems are increasing in Japan, which use robot technology and virtual reality technology. Applying these technologies make efficient medical rehabilitation outcome. We have developed 6-degrees-of-freedom (DOF) upper extremity exercise system to evaluate synergy pattern an to exercise of upper extremity of stroke patients, named ??Robotherapist??...
Rehabilitation for upper limbs is important for the elderly people, the stroked patients and so on. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology, virtual reality technology and neuroscience. In this paper we present about a development of evaluation system of the motor function for upper limbs using 3-D rehabilitation Robot ldquoEMULrdquo...
In this study, we propose a leg-robot with a compact MR fluid clutch (CMRFC) to demonstrate haptic control of abnormal spastic movements of brain-injured patients. This system can be used in the practical training for trainees of physical therapy. In this paper, basic structure and characteristics of the leg-robot are explained. Then, we suggest a control method to reproduce clonus-like movements,...
Many kinds of actuator-based (active type) haptic devices have developed and utilized as rehabilitation robots. These systems have great advantages for rehabilitative activities, for example assistive forces and so on. However, from the view point of safety, we have a room to consider utilizing brake-based (passive type) haptic devices as rehabilitation-tools. The effects and roles of active / passive...
In recent years, many researchers have studied on the rehabilitation robotics to assist medical staff or patients. Some kinds of haptic devices have been developed and evaluated its efficiency with clinical tests, for example, upper limb training for patients with spasticity after stroke. Almost all the devices for upper limb rehabilitation have only 2-DOF for its active motion except for wrists....
Several 2-DOF rehabilitation robots for upper limbs have been proposed so far, and clinical effectiveness was reported in several studies for the aged people or patients with stroke. We developed the quasi 3-DOF rehabilitation system ldquoHybrid PLEMOrdquo which has 2-DOF force-feedback function in working plane but its working plane can be adjusted the inclination. Hybrid-PLEMO is a compact, low-cost...
Rehabilitation for upper limbs is important for aged people, stroked patients and so on. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology and virtual reality technology. Applying these technologies make efficient rehabilitation possible. But there was few rehabilitation support robot system for 3-D training with high safety. Therefore we have...
Rehabilitation for upper limbs is important for aged people, stroked patients and so on. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology and virtual reality technology. Applying these technologies make efficient rehabilitation possible. But there is no rehabilitation support system that has 6-DOF for upper limbs including wrists besides application...
Rehabilitation robots are effective to evaluate quantitatively rehabilitative therapies. Some kinds of haptic devices have been developed by many researchers and evaluated its efficiency with clinical tests for example upper limb training for patients with spasticity after stroke. Almost all the devices for upper limb rehabilitation have only 2-DOF for its active motion (except for wrists). But the...
In recent years, the needs for rehabilitation support systems are increasing, basing on robot and virtual reality technology. We have developed a 6-DOF rehabilitation support system for upper limbs including wrists, named ROBOTHERAPIST. This system can measure positions and postures of an operator's hand, and generate a feedback force for their upper limbs and wrists. Considered with the safety of...
Movements of the upper limbs are indispensable for daily activities. Rehabilitation for upper limbs is important for aged people or patients of paralysis caused by stroke. Because of aging of society, the number of stroke patients will increase more in the near future. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology and virtual reality technology...
