Evaluating a Mat-Based Biometric Vibration System for Sleep and Daily Recovery
This study is looking at whether a low-frequency whole-body vibration mat can improve stress recovery, sleep, mood, and attention in healthy adults. You might be able to join if you are a healthy adult between 18 and 45 years old. The study aims to see if using the mat for 3 weeks increases heart rate variability (HRV), which is a way to measure your body's ability to recover from stress, and if it improves sleep, mood, perceived stress, and anxiety. Researchers will also look at how brain activity (measured with EEG) and HRV change. The current recruitment status is unclear.
- Study design
- This is an interventional study planning to enroll 50 healthy adult male and female volunteers. It is a randomized clinical trial.
- What's involved
- If you participate, you would use the low-frequency whole-body vibration mat at home for 15 minutes per session, 3-4 days per week for 3 weeks, preferably in the evening.
- Compensation
- Not stated in the trial record.
- Follow-up
- Measurements will be taken from enrollment to the end of treatment at 3 weeks.

What this trial measures
- Resting EEG Spectral PowerFrom enrollment to the end of treatment at 3 weeks
Eyes-closed 15-minute, supine resting EEG using a 24-channel Smarting Mobi system. Preprocessing: 0.5-30 Hz band-pass, ocular SSP, ±100 µV artifact rejection, common-average reference; clean data segmented into 10-s epochs. Outcome is band power in Theta (4-8 Hz), Alpha (8-13 Hz), Beta (13-30 Hz), averaged across all electrodes and epochs (units: power; may be log-transformed for analysis). Higher values indicate stronger oscillatory activity in each band. Primary analysis compares Post-Baseline change between groups.
- Resting EEG Directed ConnectivityFrom enrollment to the end of treatment at 3 weeks
From the same 15-minute, eyes-closed, supine EEG. Frequency-domain Granger causality computed per 10-s epoch; spectra averaged within Theta (4-8 Hz), Alpha (8-13 Hz), Beta (13-30 Hz). Connectivity summarized across all electrodes via: (a) Global directed strength (mean of all non-diagonal influences; unitless; higher = stronger overall directed connectivity); (b) Nodal inflow and outflow (sum of incoming vs. outgoing influences for each electrode; unitless; higher = stronger received/sent influence); and (c) Pairwise directed influence (value for each electrode pair; unitless). Primary analysis compares Post-Baseline change between groups, with band-specific follow-ups.
- Resting vagally mediated HRVFrom enrollment to the end of treatment at 3 weeks
Heart rate variability measured during a 15-minute, eyes-closed, supine rest in the lab. Inter-beat intervals captured with Optimal HRV; processed in Kubios (artifact correction; 4 Hz resampling; files with \>5% corrected beats excluded; spectral estimates with 300-s windows, 50% overlap). Outcomes reported as: * RMSSD (ms): Root mean square of successive differences. Higher = greater parasympathetic (vagal) activity. * HF power (0.15-0.40 Hz, ms²): High-frequency power. Higher = greater parasympathetic activity. Primary analysis compares change (Post - Baseline) between groups for each metric; an exploratory composite (mean of RMSSD and HF z-scores) may be reported to summarize parasympathetic tone.
- Longitudinal HRV Response to InterventionSession days across Weeks 1-3
RMSSD and HF recorded (i) during the 15-min home session (vibration vs quiet rest), (ii) 15 min before bedtime, and (iii) 15 min after waking. Outcomes are trajectories and group differences over time (linear mixed-effects). Benefit onset (threshold) will be explored via segmented regression/GAM change-point. Operational definition (pre-specified exploratory): first of two consecutive session-day recordings where RMSSD exceeds each participant's Baseline median by ≥0.10 log-units (\~10% increase), sustained thereafter.
