A Fabricated Force Glove That Measures Hand Forces during Activities of Daily Living.

Sensors (Basel) 2022 Feb 9;22(4). Epub 2022 Feb 9.

School of Electrical Engineering and Computer Science, Louisiana State University, Baton Rouge, LA 70803, USA.

Understanding hand and wrist forces during activities of daily living (ADLs) are pertinent when modeling prosthetics/orthotics, preventing workplace-related injuries, and understanding movement patterns that make athletes, dancers, and musicians elite. The small size of the wrist, fingers, and numerous joints creates obstacles in accurately measuring these forces. In this study, 14 FlexiForce sensors were sewn into a glove in an attempt to capture forces applied by the fingers. Read More

Non-Invasive Analysis of Motor Unit Activation During Simultaneous and Continuous Wrist Movements.

IEEE J Biomed Health Inform 2022 05 5;26(5):2106-2115. Epub 2022 May 5.

Surface electromyography (EMG) signals have shown promising applications in human-machine interfacing (HMI) systems such as orthotics, prosthetics, and exoskeletons. Nevertheless, existing myoelectric control methods, generally based on time-domain or frequency-domain features, could not directly interpret neural commands. EMG decomposition techniques have become a prevailing solution to decode the motor neuron discharges from the spinal cord, whereas only single degree-of-freedom (DoF) movements are primarily involved in the current neural-based interfaces, resulting in limited intuitiveness and functionality.

Efficacy of a Forearm Rotation Orthosis for People With a Hemiparetic Arm.

Am J Occup Ther 2021 Nov;75(6)

George S. Tomlin, PhD, OTR/L, FAOTA, is Professor, School of Occupational Therapy, University of Puget Sound, Tacoma, WA.

Importance: Insufficient voluntary forearm movements are associated with ineffective and inefficient functional performance among people poststroke. Although evidence supports the application of the occupational therapy task-oriented (OTTO) approach for this population, the training protocol does not explicitly address the role of forearm rotation movements. In addition, a need exists for theoretical support for orthotic interventions for people poststroke. Read More

Department of Kinesiology, School of Health and Human Sciences, Indiana University Purdue University Indianapolis, Indianapolis, Indiana, United States of America.

Athletes and rehabilitation specialists have used Kinesio tape (KT) to help alleviate pain symptoms. Currently, no clear mechanism exists as to why pain is relieved with the use of KT and whether the pain relieving effect is simply a placebo effect. Additionally, the most effective taping parameters (tension of tape) for pain reduction remain unknown. Read More

Evaluating the Ability of Congenital Upper Extremity Amputees to Control a Multi-Degree of Freedom Myoelectric Prosthesis.

J Hand Surg Am 2021 Oct 14. Epub 2021 Oct 14.

OrthoCarolina Hand Center, Charlotte, NC.

Purpose: To determine whether children and adults with unilateral congenital upper limb amputation can control myoelectric prostheses with multiple degrees of freedom (DOF) using pattern recognition (PR) technology.

Methods: Seven participants (age 9-62 years) with unilateral congenital transradial amputation were tested on both their residual and sound side limbs to determine proficiency in controlling a virtual prosthesis using electromyographic signals captured by an array of surface electrodes that were processed using PR technology. Proficiency was measured through a virtual environment game called the target achievement control test, in which the testing protocol asked participants to match increasingly complex prosthesis postures with 1, 2, and 3 DOF.
