Fiber-based Miniature Strain Sensor with Fast Response and Low Hysteresis.

Flexible and stretchable strain sensors are in high demand in sports performance monitoring, structural health monitoring, and biomedical applications. However, existing stretchable soft sensors, primarily based on soft polymer materials, often suffer from drawbacks, including high hysteresis, low durability, and delayed response. To overcome these limitations, we introduced a stretchable miniature fiber sensor comprised of a stretchable core tightly coiled with parallel conductive wires.

Electrodiagnostic Confirmation of Lumbar Radiculopathy and Its Association With Lumbar Central Canal Stenosis and Neuroforaminal Stenosis.

Introduction: Lumbar spinal stenosis (LSS) and lumbar neuroforaminal stenosis (LNS) are common diagnoses that plague patients with low back pain. Electrodiagnostic testing (EDX) can be used as an adjunct to investigate lower extremity radicular nerve pain and/or neurogenic claudication. However, there are only limited studies discussing the association of these diagnostic tools with radiculopathy.
