Comparative analysis of Oxa's relaxation score with Kubios
This paper demonstrates that Oxa's relaxation score is in good agreement with the widespread gold-standard cardiac analysis of Kubios.
- Oxa's stress/calmness index, which is intended to represent the sum of parasympathetic and sympathetic (inversed) activity, was compared to the gold-standard ECG analysis Kubios. A strong correlation coefficient (Pearson's r) of 0.97 was found with Kubios' PNS index and a strong inverse correlation of -0.97 with Kubios' SNS index.
- Oxa's strength lies in reaching this impressive quality for the stress/calmness index by calculating the index live when wearing Oxa (no postprocessing of data needed).
