tremor analysis

TremorLab is a research and education tool that quantifies tremor using the iPhone's accelerometer and gyroscope. MEASUREMENTS • Power spectral density (Welch) and peak frequency • RMS and peak-to-peak amplitude — in g, m/s², g², dB, or mechanical power (W, W/kg) • Dominant movement axis (principal component analysis) • 3D surface spectrogram — rotatable view of time, frequency and power • Morlet wavelet scaleogram and STFT spectrogram PROTOCOLS Rest, postural, kinetic and standing lower-limb recordings. Each protocol uses its own analysis band; the standing lower-limb protocol examines 13–18…
