Procedure and device to reduce the health burden caused by the seating and movement behaviour of a user

摘要

The invention concerns a procedure to reduce the health burden on a user (14). For this purpose, three-dimensional coordinates (17a, 17b, 17c) of selected key points (18a, 18b, 18c) of the musculoskeletal system (20) of the user (14) are determined by a sensor (16a, 17b, 17c). The three-dimensional coordinates (17a, 17b, 17c) are determined with an analysis unit (34) parameter values (28) which determine a body position (12) of the user (14). These parameter values (28) are given with parameter values (46) at the corresponding key points (18a, 18b,18c) compared to a reference position (36) by the analysis unit (34). The reference posture (36) is a predetermined posture. In addition, the analysis unit (34) determines the time period during which the user (14) assumes the posture (12) with the measured parameter values (28). A recommendation for correction of posture (12) is derived from the time period and deviation from the reference posture (36), which the user receives (14) as feedback from an output unit (38),where the feedback is based in particular on the strength of the body posture deviation (12) from the reference posture (36). Alternatively, or in addition, the response may be based on the determined strain on the musculoskeletal system.
