We used transcranial magnetic stimulation (TMS) to explore the stability of the three components of the multi-finger prehension synergy during holding a vertically oriented object vertically in the air. TMS led to close to proportional changes in the mechanical variables produced by the digits. These changes violated synergy components that took different times to restore. Patterns of co-variation of the mechanical variables produced by individual digits corresponding to the equation of statics restored first followed by a change in the magnitude of the performance variables such as grip force, total tangential force, and total moment of force. The results support the principle of superposition as applied to the prehension synergy.
