Article Synopsis
- sEMG has been the go-to method for controlling upper-limb prostheses, but its signal variability poses challenges for intricate movements.
- The study explores the potential of using ultrasonography (US) as an alternative, utilizing a combined sensory module for comparison with sEMG.
- Results showed that US performed better in some classifications, suggesting it could provide a more stable control for prosthetics, though it might need stricter measures for accuracy due to sensitivity to external factors.
Attribute-Driven Granular Model for EMG-Based Pinch and Fingertip Force Grand Recognition.
IEEE Trans Cybern
February 2021
Article Synopsis
- The paper addresses the challenge of precisely controlling a multifunctional prosthetic hand's pinch type and force using myoelectric signals.
- It introduces an attribute-driven granular model (AGrM) to classify pinch types and predict fingertip force by using additional attributes captured during EMG signal recording.
- AGrM significantly improved pinch-type recognition accuracy to 97.2% and maintained over 90% accuracy in force predictions, while being less computationally intensive than other methods.
Interface Prostheses With Classifier-Feedback-Based User Training.
IEEE Trans Biomed Eng
November 2017
Article Synopsis
- User training is crucial for improving the performance of myoelectric prosthetic devices, especially in real-time scenarios where physiological changes affect accuracy.
- The study introduces a clustering-feedback strategy that gives users visual real-time feedback on their EMG signals, helping them adjust their gestures and muscle contractions more effectively.
- Results indicate that this clustering-feedback method results in better hand motion recognition accuracy over time compared to traditional feedback methods, suggesting it can greatly benefit amputees with limited training experience.
Objective: To explore the association between the gene mutation of transcription factor Nkx2.5 and Chinese patients with congenital heart disease (CHD).
Methods: Polymerase chain reaction (PCR) and DNA sequencing were used to check 99 CHD patients and 90 normal control subjects from the Zhong Da Hospital of Southeast University.
