Abstract: Objectives: The objectives of the study were to measure and compare
handgrip strength using two instruments,
Jamar® and
Grippit® and to assess the validity and
evaluate the test-retest reliability of each instrument. Thirty-four
participants were recruited from University of Gothenburg, Sweden. Included
were apparently healthy women, right handed and aged 20–29 years. Handgrip
strength was measured with Jamar® and
Grippit® on two occasions 4–11 days
apart. Three measurements were made with each hand and instrument on two
separate occasions. The test-retest reliability of both instruments showed very
high correlations (ICC 0.87–0.95) and SRD% ranged from 12–15%. When
comparing the results obtained from both instruments, high correlations (r =
0.78–0.83) were found between all the analysed variables. The test-retest
reliability of both Jamar® and
Grippit® was very high as was the
concurrent validity between the two instruments.
