Emerging Triboelectric Nanogenerators for In‐Body Implantation

Small Methods, EarlyView.
This review explores functional implantable triboelectric nanogenerators in biomedical applications, discussing their mechanisms, electricity generation, and design approaches. To solve postimplantation challenges, four types of triboelectric nanogenerators (TENGs) are introduced: stretchable, bioadhesive, on‐demand biodegradable, and multiresponsive ...

Comparison of Benefits from Cardiac Resynchronization Therapy between Patients with Ischemic Cardiomyopathy and Patients with Idiopathic Dilated Cardiomyopathy [PDF]

Journal of Tehran University Heart Center, 2009
Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with moderate to severe heart failure. However, 20-30% of patients remain non-responders to CRT.

Differences and Commonalities of Electrical Stimulation Paradigms After Central Paralysis and Amputation

Artificial Organs, EarlyView.
Invasive and non‐invasive functional electrical stimulation (FES) is a well‐established method to partially restore function after paralysis and deliver sensory feedback after amputation. This work summarizes the current state‐of‐the‐art of FES for restoring function, supporting rehabilitation therapy, and assistive devices.

Dorsal Genital Nerve Stimulation as an Adjunctive Therapy to Control Neurogenic Detrusor Overactivity After Spinal Cord Injury

Artificial Organs, EarlyView.
People with spinal cord injury (SCI) experience bladder overactivity, which can cause incontinence. Dorsal genital nerve stimulation (DGNS) can suppress overactivity, providing a longer duration to reach a toilet. People with SCI trialed home‐based DGNS for 8 weeks. DGNS was effective in the laboratory, and participants found home‐based DGNS acceptable.

Procedimiento de Enfermería en la implantación de marcapasos transvenoso temporal.

NURE Investigación, 2013
La implantación de marcapasos transvenoso temporal (MPTT) es una técnica que consiste en estimular de forma artificial el corazón cuando los marcapasos naturales no pueden mantener el ritmo y la frecuencia adecuados.

The Neurophysiological Effects of Cervical Transcutaneous Spinal Cord Stimulation With and Without a High Frequency Carrier in Able‐Bodied Adults

Artificial Organs, EarlyView.
The Neurophysiological Effects of Cervical tSCS With and Without a High Frequency Carrier in Healthy Adults. kHz‐tSCS presents a less efficient waveform. In FCR, spinal inhibition was observed following sham and conv‐tSCS. kHz‐tSCS appeared to prevent FCR spinal inhibition.

Repetitive Grasping After Stroke Assisted by Functional Electrical Stimulation

Artificial Organs, EarlyView.
To understand whether FES can be useful in assisting functional grasping after stroke, the following requirements were investigated: (i) producing sufficient force, (ii) sustaining this force for an adequate duration, (iii) successfully releasing the object, and (iv) monitoring the onset of muscle fatigue during repetitive grasping.

Neurophysiological Effect of Transcutaneous Electrical Spinal Cord Stimulation in Chronic Complete Spinal Cord Injury

Artificial Organs, EarlyView.
TESCS‐ABT induced neurophysiological changes in individuals with chronic complete SCI, however these did not consistently translate into functional improvements. These findings highlight the role of residual supraspinal connectivity and inform future research to optimise this neurotechnology for SCI rehabilitation and identify likely responders ...
