1. A method for analyzing a motion of a human user, the method comprising:
attaching at least one motion sensor substantially near a lower back of the human user;
performing a motion measurement on the human user using the at least one motion sensor;
obtaining, by a computer over a wired or wireless interface associated with the at least one motion sensor, movement data of the human user over a time interval from the at least one motion sensor;
computing, over the time interval, a distribution of energy as a function of time associated with the motion based on the obtained movement data;
identifying energy peaks based on the distribution of the energy over the time interval;
determining an occurrence frequency of an energy peak having a unique energy value;
computing an energy-occurrence-frequency distribution as a function of energy based on the determined occurrence frequencies of energy peaks within a predetermined energy range;
determining a level of stability associated with the human user based on the computed energy-occurrence-frequency distribution; and
presenting, on a display associate with the computer, the determined level of stability to the human user.
