The advantages of the Watts-Ford test are that it is convenient for testing thin sheets or strips, it is similar to a rolling process (in manufacturing analyses), frictional effects may be minimized, there is no 'barrelling' as would occur in a cylindrical compression test, and the plane strain deformation eases the analysis.

Nerve compression is a result of poor posture, prolonged computer use is an example of repetitive strain injury which affects the musculoskeletal system. [ 16 ] [ 2 ] Whiplash injury , whereby the force causes strain to the capsule and ligaments of the apophyseal joints of the cervical spine . [ 7 ]
Generation Iron is a 2013 American documentary film which follows the world's leading professional bodybuilders as they train and compete for the 2012 Mr. Olympia.Considered to be a spiritual sequel to the 1977 documentary Pumping Iron, the film gives access to the lives of the top seven bodybuilders in the sport, including Phil Heath, Kai Greene, Branch Warren, and Dennis Wolf.
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [1] Other common names include repetitive stress injury , repetitive stress disorders , cumulative trauma disorders ( CTDs ), and overuse syndrome .
Rotator cuff tendinopathy is associated with pain over the front and side (anterolateral) of the shoulder pain that radiates towards the elbow. The pain may occur with shoulder movement above the horizontal position, shoulder flexion and abduction. [12] [13] Pain is often described as weakness. Actual muscle weakness does not correlate with ...
However, imaging studies are unable to show cause of shoulder pain in diagnosing. For example, MRI imaging would show rotator cuff pathology and bursitis but is unable to specify the cause. [15] On physical exam, the physician may twist or elevate the patient's arm to test for reproducible pain (the Neer sign and Hawkins-Kennedy test).
The Twist Compression Tester ("TCT") is a hydraulically operated bench-top apparatus used to evaluate the level of friction and/or wear between two materials under lubricated or non-lubricated conditions. Under controlled conditions, a rotating annular specimen is brought into contact with a non-rotating flat specimen.
The Neer impingement test is a test designed to reproduce symptoms of rotator cuff impingement through flexing the shoulder and pressure application. Symptoms should be reproduced if there is a problem with the supraspinatus or biceps brachii. [1] This test is also associated with the Hawkins-Kennedy Test and Jobe's Test. [2]
