Objective:
To assess whether participants were able to select the handgrip position on a Jamar hand dynamometer with which the maximal handgrip strength could be delivered, while sitting and while standing.
Design:
A criterion standard comparison study.
Setting:
A university campus in the Netherlands.
Participants:
Fifty-six healthy subjects (30 men, 26 women; mean age, 30 y; range, 19-60 y) voluntarily participated. Interventions Not applicable.
Main Outcome Measures:
Maximal handgrip strength for the self-selected and non-self-selected handgrip position of the hand dynamometer (positions 2 or 3), while sitting and while standing.
Results:
The self-selected handgrip position resulted in the highest mean maximal grip strength compared with the non-self-selected handgrip strength, both for sitting (mean difference, 2.3 kg; P
Conclusions:
Both in sitting and in standing, participants were able to self-select the handgrip position on the hand dynamometer with which the maximal handgrip strength could be delivered. Therefore, it may be useful to introduce self-selection of the handgrip position in protocols to assess the maximal handgrip strength.
