Reliability and usefulness of bulb dynamometer for measuring hand grip strength in preschool children
The aim of this study was to examine the reliability and usefulness of baseline pneumatic squeeze (bulb) dynamometer for measuring hand strength in preschool children. A total of 95 preschool children aged 5–7 years participated in the study. The equipment used in this study includes a baseline pneumatic squeeze bulb dynamometer (Baseline, USA). Non- significant differences (p > 0.05) were observed between testing sessions for Dominant (ES = trivial ; p = 0.87) and Non-dominant hand (ES = trivial ; p = 0.61). High testretest reliability (ICC > 0.90) was observed for both measures. However, CV% was above 5% in both, Dominant and Non-dominant hand. The typical error for Dominant (TE = 3.05 Kpa) and Non- dominant hand (TE = 2.85 Kpa) was greater than the presumed SWC (SWC = 1.80 Kpa and SWC = 1.87 Kpa), consequently these measures were rated as “marginal”. We observed a higher variation in handgrip strength in the group of children aged 5 to 7 years old, which might be explained by the smaller sample size compared with the other studies. Moreover, possible differences in hand sizes could also contribute to a higher variation in this age group. Future studies should also increase the sample size, especially in children with different hand sizes
