Training and Testing Database for IMU Based Gait Analysis Methods

The goal of this study is to establish a high-quality, synchronised dataset of gait events (GE) by simultaneously collecting inertial measurement unit (IMU) data and validated ground truth detections using a Vicon motion capture system. The primary objective is to address existing limitations in GE detection - such as poor generalisability, limited data diversity, and lack of precise synchronisation - through a rigorous protocol that ensures accuracy and transparency. The experiment is structured in three phases. First, Vicon-derived GE will be validated and refined using complementary modalities (force plates and video recordings). Next, deep learning (DL) algorithms will be developed and evaluated for GE detection directly from IMU data, with Vicon annotations serving as ground truth. Finally, the impact of differences in GE timing on spatiotemporal gait parameters (SGP) will be analysed to assess the feasibility of using IMU-only systems for reliable gait analysis. By achieving these objectives, the study aims to improve the accuracy of GE detection from wearable sensors and enable more accessible, scalable, and reliable gait analysis outside the laboratory environment.

Hydrogen-Rich Water and Resting Metabolism in Young Adults

The H2REST trial is a randomized, double-blind, placebo-controlled crossover study investigating the acute effects of a single dose of hydrogen-rich water (HRW) on resting metabolism in healthy young adults. Participants complete two testing sessions-receiving either HRW or placebo in a randomized order-followed by standardized metabolic testing. Primary outcomes include resting energy expenditure, respiratory exchange ratio, and substrate utilization measured via indirect calorimetry. The study aims to assess whether acute HRW intake can modulate metabolic rate and fuel preference at rest, and to explore inter-individual variability in response.

Investigating the Impact of Afferent Stimulation on Proprioceptive Function in Post-Stroke Rehabilitation

The objective of this study is to assess the functionality of a sensory stimulation device that uses mechanical vibrations and low-intensity electrical currents to deliver proprioceptive feedback to stroke patients regarding their movements.
