Evaluating movement of a subject

A computer program product embodied on a computer readable medium for evaluating movement of a subject, the computer program product comprising:

• computer code for obtaining a first signal from a first sensor, the first signal including a plurality of first measurements generated by the first sensor;
• computer code for processing the plurality of first measurements of the first signal to determine a measurement quality in the plurality of first measurements, the measurement quality based on:
• a comparison between acceleration measurements and gravitational acceleration;
• or
• variance of air pressure measurements;
• and
• computer code for determining a configuration for a movement evaluation algorithm,
• wherein the configuration of the movement evaluation algorithm is determined based on the determined measurement quality in the plurality of first measurements, and
• wherein the computer code for the determining the configuration of the movement evaluation algorithm includes at least one of:
• computer code for determining a decision threshold of the movement evaluation algorithm based on the determined measurement quality in the plurality of first measurements;
• or
• computer code for determining one or more weightings used in the movement evaluation algorithm based on the determined measurement quality in the plurality of first measurements.
