Case study

Force Plate FFT Analysis

This project analyzes force-plate CSV trial data from shod and barefoot conditions at high and low sampling rates. The workflow extracts vertical ground reaction force (GRF), estimates loading rate, evaluates center-of-pressure behavior, and uses FFT/PSD to compare frequency content across conditions.

The brief

Challenge

Determine how footwear condition and sampling rate affect measured impact characteristics while preserving signal quality and interpretability.

Approach

What we made

I implemented a MATLAB pipeline that ingests selected trials, computes GRF and loading-rate features, maps center-of-pressure behavior, and applies single-sided FFT/PSD analysis for condition-level comparison.

Built a complete MATLAB workflow for trial loading, GRF extraction, and derived metrics.
Compared shod vs barefoot behavior across high and low sampling frequencies.
Produced report visuals for COP trends, spectra, and loading-rate discussion.

Outcome

Results

Delivered a full analysis with reproducible scripts, comparative visualizations, and conclusions on impact peaks, loading behavior, and sampling-rate implications for accuracy.
