An intelligent control framework for robot-aided resistance training using hybrid system modeling and impedance estimation.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
This study presents a novel therapy control method for robot-assisted resistance training using the hybrid system modeling technology and the estimated patient's bio-impedance changes. A new intelligent control framework based on hybrid system theory...

Wrist proprioceptive acuity: A comprehensive robot-aided assessment.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Proprioception is the sense of the body awareness. Proprioceptive deficits represent frequent consequences of several neurological conditions like stroke, Parkinson's disease and others. The assessment of such somatosensory function is crucial, altho...

Comparison between the therapeutic effects of robotic-assisted locomotor training and an anti-spastic medication on spasticity.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
We studied the effects of robotic-assisted locomotor (LOKOMAT) training or an anti-spastic medication (tizanidine) on neuromuscular abnormality associated with spasticity in persons with incomplete Spinal Cord Injury (SCI). Subjects were randomly div...

Development of wrist rehabilitation robot and interface system.

Technology and health care : official journal of the European Society for Engineering and Medicine
The authors have developed a practical wrist rehabilitation robot for hemiplegic patients. It consists of a mechanical rotation unit, sensor, grip, and computer system. A myoelectric sensor is used to monitor the extensor carpi radialis longus/brevis...

Experiments and kinematics analysis of a hand rehabilitation exoskeleton with circuitous joints.

Bio-medical materials and engineering
Aiming at the hand rehabilitation of stroke patients, a wearable hand exoskeleton with circuitous joint is proposed. The circuitous joint adopts the symmetric pinion and rack mechanism (SPRM) with the parallel mechanism. The exoskeleton finger is a s...

Design of a quasi-passive 3 DOFs ankle-foot wearable rehabilitation orthosis.

Bio-medical materials and engineering
Muscular rigidity and atrophy caused by long-term underactivity usually lead to foot drop, strephenopodia, foot extorsion or some other complications for the lower limb movement disorders or lower limb surgery sufferers. The ankle-foot orthosis can h...

Trajectory planning and mechanic's analysis of lower limb rehabilitation robot.

Bio-medical materials and engineering
A new rehabilitation robot was designed. The robot included a suspension mechanism, a drive unit, and an adjustment mechanism. Additionally, innovative weight loss mechanism increased the dynamical device so that it could be used with patients of var...

Task and postural factors are related to back pain in helicopter pilots.

Aviation, space, and environmental medicine
BACKGROUND: A previous survey by Shear et al. revealed a high prevalence of back pain in Royal Navy helicopter aircrew, compared with controls. It was recommended that a second survey be undertaken, taking account of flying tasks and cockpit ergonomi...
