Measuring the Reliability of Postural Sway Measurements for a Static Standing Task: The Effect of Age.

A force plate is used to determine the ability to balance ability. However, only some medical centers or laboratories are equipped with force plates because they are costly so a low-cost force plate is required for home care or health care institutes. Few studies compare the reliability of postural sway measurements in terms of age.

Detecting slow wave sleep using a single EEG signal channel.

Background: In addition to the cost and complexity of processing multiple signal channels, manual sleep staging is also tedious, time consuming, and error-prone. The aim of this paper is to propose an automatic slow wave sleep (SWS) detection method that uses only one channel of the electroencephalography (EEG) signal.

New Method: The proposed approach distinguishes itself from previous automatic sleep staging methods by using three specially designed feature groups.
