BACKGROUND Several pilot studies have evoked interest in robot-assisted therapy (RAT) in children with cerebral palsy (CP). OBJECTIVE To assess the effectiveness of RAT in children with CP through a single-blind randomized controlled trial. PATIENTS AND METHODS Sixteen children with CP were randomized into 2 groups. Eight children performed 5(More)
BACKGROUND Manual manipulation of the camera is a major source of difficulties encountered by surgeons while performing minimally invasive laparoscopic surgery. METHODS A survey of laparoscopic procedures and a review of existing active and passive holders were conducted. Based on these analyses, essential requirements were highlighted for such devices.(More)
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(More)
OBJECTIVE To validate a protocol assessing upper limb kinematics using a planar robot among stroke patients. DESIGN Prospective cohort study. SUBJECTS Age-matched healthy subjects (n = 25) and stroke patients (n = 25). METHODS Various kinematic indices (n = 44) were obtained from 4 tasks performed by subjects with REAplan, a planar end-effector(More)
The use of kinematics is recommended to quantitatively evaluate upper limb movements. The aims of this study were to determine the age effects on upper limb kinematics and establish norms in healthy children. Ninety-three healthy children, aged 3–12 years, participated in this study. Twenty-eight kinematic indices were computed from four tasks. Each task(More)
BACKGROUND AND PURPOSE Osseous pelvic tumors can be resected and reconstructed using massive bone allografts. Geometric accuracy of the conventional surgical procedure has not yet been documented. The aim of this experimental study was mainly to assess accuracy of tumoral resection with a 10-mm surgical margin, and also to evaluate the geometry of the(More)
Series elastic actuators are very popular in rehabilitation robotics. Among other advantages, elastic elements between the actuator and the load permit to store and release energy during the task completion, such that the energy balance is improved and the motor power peak is decreased. In rhythmic tasks like walking, this reduces to design the spring(More)
