Background and Objectives: 'Diabetic hand' includes complications related to joint mobility and muscle strength with functional impairment. The objective was to compare upper extremity impairments, hand grip, pinch strength and joint mobility in patients with Diabetes Mellitus type2(T2DM) with nondiabetic subjects. Methods: Comparative cross-sectional study was conducted using purposive sampling. Thirty participants with T2DM, duration >/=5 years, age group>/=50 years were included in group A and thirty age and gender matched healthy non-diabetic controls in group B. UEFS(upper extremity functional scale) was filled by the participants. Hand Grip Strength(HGS) and Key Pinch Strength were measured using Handheld Dynamometer and Pinch Gauge respectively. Joint mobility of hand was assessed using 'Prayer sign' and 'Tabletop test'. Results: Mean±SD of HGS group A(diabetics)=18.86±5.55kg and group B(nondiabetics)= 31.73±6.76kg, Pinch Strength of group A=4.93±1.74 kg and of group B=7.4±1.10kg respectively. Mean±SD of UEFS group A=55.03±8.18 and group B=72.66±4.65 respectively. Prayer sign and Tabletop sign were positive in 7/30(23%) in group A and 1/30(3.3%) in group B. Analysis was done using Mann Whitney test and showed statistically significant difference between diabetics and non-diabetics, U=60.50,p<0.001 for HGS and U=111.0,p<0.001 for Pinch Strength and U=25.50,p<0.001 for UEFS. Conclusion: Upper extremity impairments of grip strength, mobility and function were common in patients with T2DM. [ABSTRACT FROM AUTHOR]
