Selection of an arm cuff of the right size is necessary for accurate measurement of blood pressure (BP). Incorrect measurement can result either in unnecessary investigations, treatment, and follow-up for the mistaken diagnosis of hypertension, or no treatment for hypertension in individuals mistakenly thought to have normal BP. This is of particular importance in children, who have age-depende...

Brachial artery is the main artery supplying the upper limb. Variations in brachial artery are so many that it becomes a rule rather than an exception. A study was done to note the variations in the relation of median nerve to brachial artery. A total of 95 upper limbs (51 Right, 44 Left), with a mean arm length of 30.82 cms, were studied. In 11 of the limbs (11.57%) median nerve was noted to c...

AIM To study the relationship between age-related maculopathy (ARM) and exposure to sunlight using an objective method. METHODS In a case-control study of Japanese men aged > or = 50 years (67 controls without ophthalmic disease and 148 with ARM), those with ARM were separated into groups of early (n = 75) and late (n = 73) ARM. Facial wrinkle length and area of hyperpigmentation, which are c...

We present a method for tracking the 3D position of a nger, using a single camera placed several meters away from the user. After skin detection, we use motion to identify the gesticulating arm. The nger point is found by analyzing the arm's outline. To derive a 3D trajectory, we rst track 2D positions of the user's elbow and shoulder. Given that a human's upper arm and lower arm have consisten...

PURPOSE It has been shown that eccentric actions at a long muscle length result in a larger decrease in force and more muscle tenderness compared with those at a short muscle length. To further investigate the effect of elbow joint angle on the development of muscle damage, this study compared two maximal eccentric exercise regimens in which the starting position of the action was different, bu...

the purpose of this study was to determine and compare blood lactate, heart rate and blood pressure responses in arm and leg exercises and to determine the relationship between these variables and fatigue time during these two modes of exercises. 8 young professional karate players (mean age 18.90±2.20) volunteered to participate in this study. the subjects completed two ergometers: arm and leg...

This study addressed the question of how the three-dimensional (3-D) control strategy for the upper arm depends on what the forearm is doing. Subjects were instructed to point a laser-attached in line with the upper arm-toward various visual targets, such that two-dimensional (2-D) pointing directions of the upper arm were held constant across different tasks. For each such task, subjects maint...
