Neural interfacing non-invasive brain stimulation with NIRS-EEG joint imaging for closed-loop control of neuroenergetics in ischemic stroke
Alexander von Lühmann,Jessica Addesa,Sourav Chandra,Abhijit Das,Mitsuhiro Hayashibe,Anirban Dutta +5 more
TL;DR: NIRS-EEG joint-imaging can be used to dose non-invasive brain stimulation (NIBS) - transcranial direct current stimulation (tDCS) and photobiomodulation - which may be able to provide therapeutic options for patients with energetic insufficiency by modulating the cortical neural activity and hemodynamics.
Journal ArticleDOI
A Practical Approach to the Design and Development of Tele-Operated Surgical Robots for Resource Constrained Environments—A Case Study
Karthik Chandrasekaran,Suraj Parameswaran,Srikar Annamraju,Sourav Chandra,Ramalingam Manickam,Asokan Thondiyath +5 more
TL;DR: This research work elaborates on the methodology followed by us for the complete system design, methods for simplifying the surgical tool design with decoupled DoF wrist utilizing stationary wire guides instead of pulleys, and method of reducing the number of balancing masses required for gravity compensation of master manipulator arms.
Proceedings ArticleDOI
Variations of Tendon Tap Force Threshold needed to Evoke Surface Electromyogram Responses after Botulinum Toxin Injection in Chronic Stroke Survivors
TL;DR: This work explored the effect of BT on the amplitude of the smallest tendon tap force required to elicit a detectable biceps brachii surface electromyogram (sEMG) reflex response and hypothesized that after BT injection, the force threshold would increase due to a decrease in available efferent activation.
Journal ArticleDOI
Anomalies of motor unit amplitude and territory after botulinum toxin injection
TL;DR: The observed covariation of the amplitude and the territory area indicates that the large amplitude MUs that appeared after the BT injection have a relatively smaller territory area.
Proceedings ArticleDOI
Effect of Botulinum Toxin on the Spatial Distribution of Biceps Brachii EMG Activity Using a Grid of Surface Electrodes: A Case Study
TL;DR: Evidence of alteration of the amplitude and pattern of muscle activity after botulinum toxin injection is observed and the capability of grid recordings to detect these pattern changes is documented.
