Theme: The aim of the pilot study was to examine the biomechanics and static of the entire spine during piano playing using two kinemetric methods in view of the validity and reliability of the examination results.

Material and methods: Three pianists were examined over 10 consecutive days using specifically defined exercises related to piano playing. The measurements were recorded during a concert. The following methods were used: The ORTHOSON, an Online-6-hour-measuring device which measures the spine in every position and the 3-D- Zebris-Spine-Mobility which records all spinal movement 3 dimensionally.

Results: Concerning validity and reliability both methods are suitable to assess the biomechanical and static measurement of movement. Through the finely segmented biomechanical assessment, the 3-D-spine-report of the Zebris-device allows for more detailed information. The ORTHOSON on the other hand is a transportable device which allows biomechanic and static parameters of spinal strain to be measured online during concerts, performances and lengthy practise sessions.

Conclusion: The 3-D-measuring device ORTHOSON is suitable to measure the course of movement and posture of pianists playing over a time period of 6 hours as it produces reliable statements which fulfil the requirements of measurement methods in view of validity and reliability. The 3-D-Zebris-Spine-Mobility-Program is mainly suitable for the verification of segmented examinations with regard to movement disorders as well as to allow specific segmental therapeutic diagnoses
