Sensitivity analysis guided improvement of an electromyogram-driven lumped parameter musculoskeletal hand model.

J Biomech 2022 Jun 16;141:111200. Epub 2022 Jun 16.

UNC-NC State Joint Department of Biomedical Engineering, North Carolina State University, Raleigh, NC 27695, United States; UNC-NC State Joint Department of Biomedical Engineering, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, United States. Electronic address:

EMG-driven neuromusculoskeletal models have been used to study many impairments and hold great potential to facilitate human-machine interactions for rehabilitation. A challenge to successful clinical application is the need to optimize the model parameters to produce accurate kinematic predictions. In order to identify the key parameters, we used Monte-Carlo simulations to evaluate the sensitivities of wrist and metacarpophalangeal (MCP) flexion/extension prediction accuracies for an EMG-driven, lumped-parameter musculoskeletal model.

Functional improvement by body-powered 3D-printed prosthesis in patients with finger amputation: Two case reports.

Medicine (Baltimore) 2022 Jun 24;101(25):e29182. Epub 2022 Jun 24.

Rehabilitation Center, Incheon Workers' Compensation Hospital, Incheon, Korea.

Rationale: The most common upper limb amputations are finger amputations, resulting in functional limitations that lead to problems with activities of daily living or job loss. For many years, prosthetic options for finger amputations have been limited to passive prostheses. In many countries including South Korea, body-powered finger prostheses have rarely been prescribed due to high cost, lack of experience of physicians and prosthetists, low interest and no coverage by insurance benefits.

Simultaneous control of 2DOF upper-limb prosthesis with body compensations-based control: a multiple cases study.

IEEE Trans Neural Syst Rehabil Eng 2022 Jun 24;PP. Epub 2022 Jun 24.

Controlling several joints simultaneously is a common feature of natural arm movements. Robotic prostheses shall offer this possibility to their wearer. Yet, existing approaches to control a robotic upper-limb prosthesis from myoelectric interfaces do not satisfactorily respond to this need: standard methods provide sequential joint-by-joint motion control only; advanced pattern recognition-based approaches allow the control of a limited subset of synchronized multi-joint movements and remain complex to set up.

An algorithmic diagnostic approach to scapholunate ligament injuries based on comparison of X-ray examinations and arthroscopy in 414 patients.

J Plast Reconstr Aesthet Surg 2022 May 4. Epub 2022 May 4.

Department of Hand, Plastic, Reconstructive and Burn Surgery, BG Trauma Center, Eberhard Karls University Tuebingen, Schnarrenbergstr. 95, 72076 Tuebingen, Germany.

Conventional X-ray imaging is usually the first diagnostic assessment after clinical examination in case of suspected scapholunate interosseous ligament (SLIL) injury. Nevertheless, there is no consensus on the norms of the scapholunate distance (SLD) or carpal angles. Therefore, we aimed to determine the utility of static and dynamic radiographs in the diagnostic of an SLIL injury in comparison with the reference standard arthroscopy. Read More
