A Hybrid Knee Exoskeleton Using Real-Time Ultrasound-Based Muscle Fatigue Assessment

Sheng, Z., Iyer, A., Sun, Z., Kim, K., & Sharma, N. (2022, May 19). IEEE-ASME TRANSACTIONS ON MECHATRONICS, Vol. 5.

By: Z. Sheng *, A. Iyer n, Z. Sun n, K. Kim & N. Sharma n 

Contributors: Z. Sheng *, A. Iyer n, Z. Sun n, K. Kim & N. Sharma n 

author keywords: Muscles; Ultrasonic imaging; Exoskeletons; Switches; Iron; Fatigue; Control systems; Control design; closed loop system; delay system; motion control; nonlinear control system; rehabilitation robotics; robust control; switching systems; state feedback; ultrasonic imaging
TL;DR: Results from the first experimental demonstration of a hybrid knee exoskeleton that uses ultrasound-derived muscle state feedback to coordinate electrical motors and FES are presented, suggesting a potential application in the rehabilitation of neurological disorders like spinal cord injuries and stroke.

Ultrasound Imaging-Based Closed-Loop Control of Functional Electrical Stimulation for Drop Foot Correction

Zhang, Q., Lambeth, K., Iyer, A., Sun, Z., & Sharma, N. (2022, September 30). IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY, Vol. 9.

By: Q. Zhang n , K. Lambeth n, A. Iyer n, Z. Sun n & N. Sharma n 

Contributors: Q. Zhang n , K. Lambeth n, A. Iyer n, Z. Sun n & N. Sharma n 

author keywords: Ankle dorsiflexion; drop foot; functional electrical stimulation (FES); nonlinear control; sampled-data observer (SDO); ultrasound (US) imaging
TL;DR: The use of ultrasound (US) echogenicity as an indicator of FES-evoked muscle activation is explored and a methodology to integrate US in an FES control framework is provided, which will likely benefit persons with drop foot and those with other mobility disorders. (via Semantic Scholar)

A Dual-Modal Approach Using Electromyography and Sonomyography Improves Prediction of Dynamic Ankle Movement: A Case Study

IEEE TRANSACTIONS ON NEURAL SYSTEMS AND REHABILITATION ENGINEERING, 29, 1944–1954.

By: Q. Zhang n , A. Iyer n, Z. Sun n, K. Kim  n & N. Sharma n 

Contributors: Q. Zhang n , A. Iyer n, Z. Sun n, K. Kim  n & N. Sharma n 

author keywords: Imaging; Sensors; Legged locomotion; Feature extraction; Neuromuscular; Dynamics; Biomedical imaging; B-mode ultrasound imaging; surface electromyography; machine learning regression; dynamic ankle dorsiflexion motion; human limb intent
MeSH headings : Ankle; Ankle Joint; Electromyography; Humans; Movement; Muscle, Skeletal
TL;DR: The findings show that potentially the dual-modal sensing approach can be used as a superior sensing modality to predict human intent of a continuous motion and implemented for volitional control of clinical rehabilitative and assistive devices. (via Semantic Scholar)
