Model SOMNOwatch™ plus -Actigraphy
Long recording times (up to 25 days!), Research Grade Sensors, High sampling rates - Up to 256/32 Hz, Data Compression for long recording times, Up to 8 External Channels - BP, Resp, 6 x EEG, and more..., Double Plot & Raster View - for improved circadian analysis. The SOMNOwatch™ plus is a powerful, miniaturised actigraphy and multi channel recorder which is as comfortable and user-friendly as a watch. As any multi-channel system, the SOMNOwatch™ plus can replace several devices while providing excellent signal quality. Our SOMNOwatch™ plus actigraphy encases a digital triaxial accelerometer, ambient light sensor and event marker. Its small, easy to use and offers long recording times. Combined with additional modules, the SOMNOwatch ™ plus can also be used flexibly as a 1-channel long-term EEG, long-term ECG, respiratory screener or PLM recorder.

The high frequency acquisition of movement data enables the SOMNOwatch™ plus to make a very accurate frequency analysis using FFT. The recording of tremor intensity and tremor frequency can be achieved over a long period of time. This parameter can be used for the medical diagnosis and treatment of Parkinson’s disease.
Analysis Software
- Programmable, delayed auto start
- Spectral Analysis to detect tremor
- Easy determination of Frequency and Intensity in the Tremor Spectrum
- Fast results output in a tabular or graphical format
- Export to Microsoft EXCEL
Applied to the ankle, the SOMNOwatch™ plus can continuously record Leg Movement for up to 5 nights. It can differentiate between the standing and lying position by using the integrated position sensor. With adjustable parameters, the software automatically recognizes PLM movement patterns and evaluates the PLM index. For RLS-rating (Restless Leg Syndrome) the Motor activity is quantified.
For an extended diagnosis the correlation of PLMs and Cortical Micro Arousals can be detected by using the EEG Derivation (optional).
For the detection of PLM on both legs, an external movement sensor can be fixed to the second leg, and work simultaneously with the SOMNOwatch™ plus.
The SOMNOwatch™ plus is validated for the detection of periodic leg movements*.
