Background: The radial artery (RA) is a continuation of the brachial and one major blood supplying vessels to structures forearm. It originated in cubital fossa at level neck radius. runs on lateral aspect forearm before it reaches wrist branches out supply hand. RA also important clinically due its location wrist, as can be felt pulse used determine heart rate. choice for coronary angiography,...

We studied skin color in participants before and after a 100-m sprint using Konica Minolta CM-2600d spectrophotometer. Four body positions (forehead, cheek, neck, inner forearm) were measured for the approximately 30 students (non-professional runners) who participated experiment. Skin reflectance was three times at each position running again soon afterward. Analysis of data showed that averag...

BACKGROUND The use of forearm crutches has been associated with pain and neuropraxia along the ulnar bone. Whilst anatomic grips have improved comfort of crutch walking, to date anatomic forearm cuffs have not been clinically evaluated. The aim of this clinical pilot study was to determine if the use of forearm crutches with anatomic cuffs reduces pain and increases comfort and function in long...

Background: Congenital radial club hand (RCH), as a rare congenital deformity of the upper extremity, is characterized by a wide spectrum of malformations including radial deviation. Centralization surgery is the standard treatment for severe cases that have been associated with a high rate of recurrence. This study reports the long-term results and recurrence rate of radial deviation following...

We used the insulin-perfused human forearm model to assess the effects of vasoconstriction induced with norepinephrine on the extraction of glucose in the forearm in two groups of healthy young volunteers. The norepinephrine findings were compared with a previously studied group in which vasoconstriction has been caused by reflex activation of the sympathetic nervous system. The aim of the stud...

1. An investigation was carried out in five healthy lean adults to assess whether forearm and calf plethysmography largely reflect muscle blood flow as measured by 133Xe and whether there is substantial variability in the blood flow to muscles located at different sites in the body. 2. Blood flow to forearm and calf flexors and extensors, biceps, triceps and quadriceps was assessed using the 13...

Split, gabled keyboard designs can prevent or improve upper extremity pain among computer users; the mechanism appears to involve the reduction of awkward wrist and forearm postures. This study evaluated the effects of changes in opening angle, slope and height (independent variables) of a gabled (14 degrees) keyboard on typing performance and upper extremity postures. Twenty-four experienced t...

BACKGROUND When the upper arm (area from shoulder to elbow) is inaccessible and/or a standard-sized blood pressure cuff does not fit, some healthcare workers use the forearm to measure blood pressure. OBJECTIVE To compare automatic noninvasive measurements of blood pressure in the upper arm and forearm. METHODS A descriptive, correlational comparison study was conducted in the emergency dep...

A brief hammer tap applied passively (by the experimenter) to the forearm elicits a short-latency reflex response in the forearm flexors and extensors. When the same tap is performed actively (by the subject) using the opposite forearm, the reflex response is preceded by a short-lasting anticipatory reduction in the muscle activity appearing around the impact. This anticipatory reduction is int...
