Objective: Playing cello is cooperated by complicated hands movements. The right hand is holding and pulling the bow, and the left hand is pressing string and shifting the pitch .The right hand and the left hand skillfully coordinate in playing the cello together. The wrist plays an important role in such playing. This study aims to investigate the wrist kinematics in cello playing. Methods: We use Flexible Electrical Goniometer and DataLog to record the wrist kinematics while playing the cello continuously. Three cello players in different levels: cello teacher, advanced, and elementary student were subjects to play the scores on recording. The characteristics and the difference among the three players in wrist kinematics were analyzed. Results: When the speed of the scores got faster, the range of right wrist motion became smaller. The time difference in flexion/ulna deviation and extension/radial deviation of the teacher was also smaller than advanced student, and than the elementary student, orderly. Conclusion: The results can apply on cello-playing education, the cello teacher can correctly teach the wrist movement students and to avoid wrong wrist movement according to our ergonomic analysis.
