A method and apparatus are for determining a medical biomarker indicative of a neurodegenerative disease. The method includes receiving motion data from a sensor held or mounted for rotation with a body part of the user during a repeated rotational motion of the body part. The motion data are provided relative to a frame of reference associated with the sensor. The motion data are processed to identify orientation in the frame of reference associated with the sensor of primary, secondary, and tertiary axes of rotation for the motion of the body part of the user, each of the primary, secondary and tertiary axes being mutually perpendicular to one another. A medical biomarker is extracted by analysing the rotational motion of the body part of the user about the primary, secondary and tertiary axes.

The movement of a part of human body, e.g. a limb, is monitored. The movement includes N iterated rotations in a plane. A sensing device is fixed to the limb and provides data indicative of the limb movement. These data are processed to generate a rotation signal. Then, portions of the rotation signal corresponding to each movement iteration are identified. To this purpose, a plurality of null-velocity instants is identified, wherein the angular velocity of the sensing device is null. Then, each null-velocity instant is classified as a candidate start/end time or a candidate peak time. Then, a start time, end time and peak time for each iteration are determined as a combination of two candidate start/end times and a candidate peak time that fulfils certain conditions on the values of the rotation signal in correspondence of candidate start/end times and candidate peak times.

The apparatus can further include a pivot joint pivotably supporting the support frame whereby the support frame defines and is laterally pivotable within a support frame pivot plane.

A photoplethysmography (PPG) circuit obtains PPG signals at one or more wavelengths. The PPG signal is processed to identify motion artifacts. The motion artifacts are correlated with predetermined PPG signal patterns associated with movement of a body part or a control command for a user device. The PPG signals may thus be used to detect movement of the body part or determine a control command. A user device may be controlled in response to the determined control command.
