PREDICTION OF JAMAR GRIP STRENGTH VALUE USING MODIFIED ANEROID SPYHGMOMANOMETER CUFF METHOD
ABSTRACT: To examine the
prediction of Jamar grip strength value by using aneroid sphygmomanometer cuff
method in adults.
Methods: This study involved 120 subjects, aged 20–59 years old. The grip
strength of subjects were measured using Jamar dynamometer and aneroid
sphygmomanometer cuff method. Spearman analysis was used to evaluate the
correlation between variables and grip strength. Forward stepwise was used to
analyze the regression of Jamar dynamometer using aneroid sphygmomanometer cuff
method.
Results: There was a weak correlation (r<0.4) between grip strength
with age and BMI, moderate correlation (r = 0.4–0.6) for grip circumference,
and also strong correlation r= (0.6–0.8) for sex, hand length, and hand width.
Jamar grip strength value can be predicted using spyghmomanometer with the
formula of (0.1157 x Sphygmomanometer grip strength value) – (5.696 x sex) +
(0.0824 x age) (female =1, male= 0).
Conclusions: Grip strength correlates with physiological variables. The
variables to predict Jamar grip strength using sphygmomanometer are sex and
age. Regression analysis shows that spyhgmomanometer can be used as an
alternative to measure grip strength and has a valid value to predict the Jamar
grip strength value.
