The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up. [1] Once rotated, the clinician pushes down on either the wrists or the elbow, and the patient is instructed to resist the downward pressure.
The objective was to construct two 7.6 m-diameter (25 ft) rail tunnels, 30 m (98 ft) apart, 50 km (31 miles) in length; a 4.8-metre-diameter (16 ft) service tunnel between the two main ones; pairs of 3.3 m (10 ft 10 in)-diameter cross-passages linking the rail tunnels to the service tunnel at 375 m (1,230 ft) spacing; piston relief ducts 2 m (6 ...
The selection of the strain rate is very important because the susceptibility to cracking may not be evident from result of tests at too low or too high strain rate. For numerous material-environment systems, strain rates in range 10 −5 - 10 −6 s −1 are used; however, the observed absence of cracking at a given strain rate should not be ...
Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area. [2]
Jobe's test is a physical exam test that is used to detect anterior shoulder instability. It is used to distinguish between anterior instability and primary shoulder impingement. This test should be performed after the Apprehension test. [3] This test was named for Christopher Jobe. [4]
Rotator cuff injury, rotator cuff disease: Some of the muscles of the rotator cuff, with a tear in the supraspinatus muscle: Specialty: Orthopedics: Symptoms: Shoulder pain, weakness [1] Types: Partial, complete [2] Diagnostic method: Based on symptoms, examination, medical imaging [2] Differential diagnosis
This is not true since the actual area will decrease while deforming due to elastic and plastic deformation. The curve based on the original cross-section and gauge length is called the engineering stress–strain curve, while the curve based on the instantaneous cross-section area and length is called the true stress–strain curve. Unless ...
A meta-analysis in 2008 concluded that the diagnostic accuracy of individual tests in the shoulder examination was limited, specifically that the Hawkins–Kennedy test and the Speed test have no discriminatory ability to diagnose specific shoulder pathology, and that results of studies evaluating other tests were too statistically ...
