|Associations between measures of transcallosal inhibition and age-related variations in unimanual performance of the right hand and left hand|
|Direction of motor transcallosal inhibitiona||Manual performance|
|Dexterity (GPT)||Grip strength (Pinch dynamometer)|
|Left to right||Right Hand|
|LTI||r= 0.59***||r= −0.37|
|TCT||r= 0.50**||r= −0.46*|
|iSP area||r= −0.46*||r= 0.38*|
|Right to left||Left Hand|
|LTI||r= 0.50**||r= −0.33|
|TCT||r= 0.42*||r= −0.44*|
|iSP area||r= −0.57**||r= 0.49**|
a The direction of transcallosal inhibition corresponds to the ispsilateral inhibition induced from the stimulated hemisphere towards the opposite hemisphere during voluntary contractions.
