Background
The aim of this study was to examine the effect of the side of brain lesion on the
ipsilesional hand function of stroke survivors.
Methods
Twenty-four chronic stroke survivors, equally allocated in 2 groups according to the
side of brain lesion (right or left), and 12 sex- and age-matched healthy controls
performed the Jebsen-Taylor Hand Function Test (JTHFT), the Nine-Hole Peg Test (9HPT),
the maximum power grip strength (PwGSmax) test, and the maximum pinch grip strength (PnGSmax) test. Only the ipsilesional hand of the stroke survivors and both hands (left and
right) of the controls were assessed.
Results
PwGS max and PnGS max were similar among all tested groups. Performances in JTHFT
and 9HPT were affected by the brain injury. Individuals with left brain damage showed
better performance in 9HPT than individuals with right brain damage, but performance
in JTHFT was similar.
Conclusions
Individuals after a brain injury have the capacity to produce maximum strength preserved
when using their ipsilesional hand. However, the dexterity of their hands and digits
is affected, in particular for stroke individuals with right brain lesion.
