Protocol Steps
Position the rat
Lift the rat by the tail to allow gripping of the device bar with forearms
View evidence from paper
“The rats were lifted from their tails to grip the device bar with their forearms”
Allow gripping
Allow the rat to grasp the bar with its forearms
View evidence from paper
“grip the device bar with their forearms and gently pulled after grasping the bar”
Apply gentle pulling force
Gently pull the rat after it has grasped the bar
View evidence from paper
“gently pulled after grasping the bar”
Record maximum force
Record the maximum value displayed on the digital force indicator before the rat releases the bar
View evidence from paper
“The maximum value the digital force indicator provided before releasing the bar was defined as the grip force”
Repeat test
Repeat the test three times in a row for each rat
View evidence from paper
“The test was repeated thrice in a row”
Calculate mean value
Calculate the mean value of the three grip force measurements
View evidence from paper
“the mean value of the holding force was considered”
