Aim. Setting reference parameters for the power grip in healthy subjects with the purpose of extending the analysis to study the complete function of the hand, also in pathology.
Methods. Thirty-four healthy, right-handed subjects (average age=23.88±4.22 years) were required to do: 1) alternated contractions at maximum frequency for 15 s; 2) alternated contractions with maximum strength for 15 s. All data were computer registered through an analogical/digital interface with the Acq Knowledge® software .
Results. Two patterns were identified: one characterised by 2 agonistic bursts and one antagonistic burst (“3-phase pattern”); the second, common in most subjects, consisted of one agonistic burst followed by the corresponding antagonistic burst.
Conclusions. There seemed to be a connection bet-ween the double burst pattern and the movement of the wrist. Such data could then be used to define the deficit and create suitable support splints.
