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...
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??...
Strengthening muscle force by training, e.g., an isokinetic exercise is used widely used method in the rehabilitation medicine and sports medicine. However, many conventional isokinetic exercise machines cannot be used safely and easily. In this study, we developed an isokinetic and iso-contractile exercise machine, named ldquoMEM-MRBrdquo, using an ldquoMR brakerdquo. This brake includes MR fluid...
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,...
We developed a compact and low-cost quasi-3-DOF rehabilitation system ldquoHybrid-PLEMOrdquo for upper limbs of stroke patients. Hybrid-PLEMO has 2-DOF force feedback function in working plane, its working plane can be adjusted the inclination, and it can be switched between active type and passive type. However, there are some directions and link positions which are difficult to display the force...
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...
Strengthening muscle force by training, e.g., an isokinetic exercise is widely used in rehabilitative activities or sports rehabilitations. However, many conventional isokinetic exercise machines cost expensive depending on its actuation device and safety system (hardware and software). In this study, we have developed highly safe isokinetic exercise systems using only brakes with functional fluids...
