Accelerometric Classification of Resting and Postural Tremor Amplitude

Sensors, 2023
Clinical rating scales for tremors have significant limitations due to low resolution, high rater dependency, and lack of applicability in outpatient settings.

Membrane-Based Optomechanical Accelerometry

Physical Review Applied, 2023
Optomechanical accelerometers promise quantum-limited readout, high detection bandwidth, self-calibration, and radiation pressure stabilization. We present a simple, scalable platform that enables these benefits with nano-$g$ sensitivity at acoustic frequencies, based on a pair of vertically integrated Si$_3$N$_4$ membranes with different stiffnesses ...

Statistical and Machine Learning Models for Classification of Human Wear and Delivery Days in Accelerometry Data

Sensors, 2021
Accelerometers are increasingly being used in biomedical research, but the analysis of accelerometry data is often complicated by both the massive size of the datasets and the collection of unwanted data from the process of delivery to study participants.

Relationship of the sacral slope with early gait derangements in robust older women

Advances in Rheumatology, 2021
Background Trunk pelvic dissociation is fundamental to the compensatory mechanism for muscle weakness during body bending. We carried out an early investigation of gait changes in a sample of community-dwelling women ≥60 years without gait complaints ...

Multicolor particle shadow accelerometry [PDF]

Measurement Science and Technology, 2015
This paper describes the extension of multicolor particle shadow velocimetry (CPSV) to the measurement of local acceleration in an Eulerian frame of reference. A validation experiment was conducted on a pendulous disk undergoing unsteady rigid body rotation.

Use of a Collar-Mounted Triaxial Accelerometer to Predict Speed and Gait in Dogs

Animals, 2021
Accelerometry has been used to measure treatment efficacy in dogs with osteoarthritis, although interpretation is difficult. Simplification of the output into speed or gait categories could simplify interpretation.
