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.
