Method and device for the simultaneous analysis of ambulatorily recorded movements of an individual's different body parts
First Claim
1. Method for analysis of movements of several different parts of an individual'"'"'s body recorded by ambulatory measurement comprising registering the movements of several different parts of an individual'"'"'s body by an accelerometer attached to each body part to be monitored, storing a signal from each accelerometer into memory, retrieving the signals registered by the accelerometers from the memory and synchronously conducting the signals retrieved from the memory to a detector thereby enabling simultaneous monitoring of the movements of the different body parts.

Abstract
A method and apparatus for the analysis of movements of several different parts of an individual'"'"'s body recorded by ambulatory measurement involves registering the movements by an accelerometer attached to each body part to be monitored and storing the signals in memory. The signals registered by the different accelerometers are retrieved from the memory and conducted synchronously to a detector to thereby enable simultaneous monitoring of the movements of the different body parts. Signals based on movements of the limbs, head and/or the middle body and, if desired, signals based on other functions of the body like eye movements, breathing or pulsation of the heart are conducted synchronously to the detector to allow simultaneous monitoring of the movements of the various body parts and other functions of the body. The result is a precise qualitative and quantitative characterization of an individual'"'"'s overall motor functions.

- 7. Apparatus for analysis of movements of several different parts of an individual'"'"'s body by ambulatory measurements, the apparatus comprising a plurality of accelerometers each adapted to be attached to a different part of a individual'"'"'s body for producing a signal indicative of movements of the different parts of the individual'"'"'s body, a detector into which the signals registered and stored by the accelerometer attached to each body part to be monitored is fed, and several channels for feeding the signals registered by different accelerometers to the detector to thereby allow simultaneous monitoring of several body parts.
