Abstract
Background: The modified sphygmomanometer and Jamar grip dynamometer are important tools to measure the hand grip strength (HGS). Aim of Study: Is to test the concurrent validity, interrater and test-retest reliability of bag modified sphygmomanometer and Jamar grip dynamometer. Subjects and Methods: Seventy patients of distal radi-us fracture (67 colles’ and 3 smith fracture) with mean age 45.03±10.45 years, were recruited to evaluate the grip strength by Jamar grip dynamometer and bag modified sphygmoma-nometer after being updated with the aneroid sphygmomanom-eter (KBM). Validity was explained by the correlation between the strength of hand grip that was assessed by modified sphyg-momanometer and Jamar dynamometer by Person Correlation Coefficient. Test-retest reliability and inter-rater reliability were expressed as Intra-class Correlation Coefficients (ICCs). All data was analyzed by (SPSS) version 25 for windows. Results: There was a correlation between strength of hand grip that was assessed by modified sphygmomanometer and Ja-mar dynamometer; was strong correlation with positive signif-icant in concurrent validity (r=0.852, p=0.001), The modified sphygmomanometer showed excellent in test-retest reliability with Intraclass correlation coefficient (ICC) was 0.996 and in interrater reliability with 0.993 Intraclass correlation coeffi-cient. Conclusion: The bag modified sphygmomanometer is a concurrently valid, test-retest and interrater reliable device to measure hand grip of distal radius fracture patients with differ-ent gender and fixation types.
