Loading on the limbs has a powerful influence on locomotion. In the present study, we examined whether robotic-enhanced loading during treadmill training improved locomotor recovery in rats that were spinally transected as neonates. A robotic device applied a force on the ankle of the hindlimb while the rats performed bipedal stepping on a treadmill. The robotic force enhanced loading during th...

OBJECTIVE To compare kinematic indices in age-matched healthy subjects and stroke patients, by evaluating various tasks performed with a robotic device, and to provide an objective and standardized protocol to assess upper limb impairments in stroke patients. DESIGN A prospective cohort study. SUBJECTS Age-matched healthy subjects (n = 10) and stroke patients (n = 10). METHODS Various kin...

Compliance has been exploited in various forms in robotic systems to allow rigid mechanisms to come into contact with fragile objects, or with complex shapes that cannot be accurately modeled. Force feedback control has been the classical approach for providing compliance in robotic systems. However, by integrating other forms of instrumentation with compliance into a single device, it is possi...

Three-dimensional (3D) printing has a variety of applications, from efficient iterations of engineering designs to fabrication of tissues for regenerative medicine. In soft robotics, 3D-printed functional materials can be used to mimic biological functions. Soft robotics overcomes some of the limitations of traditional rigid-body robotics through the ability to conform to different shapes and t...

Purpose: To investigate a robot assistance device for CT-guided percutan liver biopsy. Materials and Methods: The liver of a corpse was equipped with target dummies. Four radiologists used a 16 G needle to perform biopsy of the target region in standard free hand technique and then used a robot system which allowed planning and aligning the trajectory path. Accuracy in terms of needle tip devia...

Abstract Degenerative spine problems and spinal deformities have high socio-economic impacts. Current surgical treatment is based on bony fusion that can reduce mobility function. Precise descriptions of the biomechanics normal, deformed, degenerated segments under in vivo conditions are needed to develop new approaches preserve This study developed a system intraoperatively measures three-dime...
