Effects of transcranial magnetic stimulation of the primary motor cortex on the grip and net forces in the tripod grasp
Transcranial magnetic stimulation (TMS) is a tool
of choice to study the functionality of the corticospinal
pathway in the intact human. In this study, we used
TMS to stimulate the hand area of the primary motor
cortex (M1) and measured TMS-evoked forces in a
multi-fingered grasp. This short report aims at
presenting the experimental setup and some
preliminary results. The analysis of the data from one
subject suggests that TMS affects differently the grip
force (which measures the overall force involved in the
grasp) and the net force (which measures the net effect
of all contact forces exerted on the object)
