Evaluation of EMG, force and joystick as control interfaces for active arm supports

Background: The performance capabilities and limitations of control interfaces for the operation of active movement-assistive devices remain unclear. Selecting an optimal interface for an application requires a thorough understanding of the performance of multiple control interfaces. Methods: In this study the performance of EMG-, force- and...

Evaluation of EMG, Force and Joystick as Control Interfaces for Active Upper-Extremity Movement-Assistive Devices

Currently, many different control interfaces for the operation of active movement-assistive device exist but their respective performance capabilities and limitations remain unclear. The goal of this study was to quantitatively evaluate the performance and learning characteristics of EMG-, force- and hand joystick-based interfaces. The human...

Continuous Impedance, Force, and Acceleration Monitoring for Motion Artefact Reduction in EEG

Electroencephalograph (EEG) is used in various applications such as diagnosing patients suffering from epilepsy or seizures. Motion artefact is the noise recorded together with the desired biopotential signals. It is mainly introduced by the relative motion between the measurement electrode and the human scalp. Dry electrodes are preferred in...

Forces in the Shoulder Joint: On validation of musculoskeletal shoulder models

Detailed information about muscle forces in the human musculoskeletal system are highly demanded for several applications. Unfortunately, the measurement of muscle forces in-vivo is hardly possible. To date, musculoskeletal models are best alternative for the direct measurement of these forces. A major concern in musculoskeletal modeling is,...

Probing forces of menisci: What levels are safe for arthroscopic surgery

Purpose To facilitate effective learning, feedback on performance during arthroscopic training is essential. Less attention has been paid to feedback on monitoring safe handling of delicate tissues such as meniscus. The goal is to measure in vitro probing forces of menisci and compare them with a theoretical maximum probing force (TMPF). Method...
