A Psychophysical Approach for Predicting Isometric Endurance Limit in the Jordanian Diabetes Mellitus Patients

Diabetes is a long-term chronic disease that exhibits long-term effects that affect patients throughout their lives; Latest research shows that hand-grip strength is a significant factor in influencing an individual's performance in general. In this research, hand-grip strength is linked with Diabetes Fatigue Syndrome (D.F.S.) due to alterations in blood glucose levels to be used as a subjective sense of tiredness and reduced physical function. This research measures the Isometric Endurance Limit for hand muscles, considered a reliable tool for patient physical assessment. The research subjects consist of 49 (20 females and 29 males) Jordanian under-treatment diabetes patients examined in the actual research sample aged between 21 to 63 years old at The King Hussein Cancer Center (K.H.C.C.) (Diabetes and Endocrinology clinic), a psychophysical methodology applied by using used a digital hand grip dynamometer to measure the Isometric Endurance Limit data. The research investigated the effect of four different factors (Age, Smoking, Height, Body Mass Index (B.M.I.), and Hand Grip Circumference (H.G.C.) on Isometric Endurance Limit, and the research experiment results were analyzed with mathematical modeling, Diabetes Mellitus Patients significantly affect MVC values, whereas Limited effects are found for B.M.I., Height, Age, and Gender.
