Some examples of symptoms experienced by patients with<unk>  are aching, pulsing pain, tingling and extremity weakness, initially presenting with intermittent discomfort and then with a higher degree of frequency. Definition<unk>  <unk>  and associative trauma orders are umbrella terms used to refer to several discrete conditions that can be associated with<unk>  tasks, forceful exertions, vibrations, mechanical compression, sustained or awkward positions, or<unk>  eccentric contractions. The exact terminology is controversial, but the terms now used by the United States Department of Labor and the National Institute of Occupational Safety and Health (NIOSH) are musculoskeletal disorders (MSDs) and work-related muscular skeletal disorders (WMDs). Examples of conditions that may sometimes be attributed to such causes include tendinosis (or less often tendinitis), carpal tunnel syndrome, cubital tunnel syndrome, De Quervain syndrome, thoracic outlet syndrome, intersection syndrome, golfer's elbow (medial epicondylitis), tennis elbow (lateral epicondylitis), trigger finger (so-called stenosing tenosynovitis), radial tunnel syndrome, ulnar tunnel syndrome, and focal dystonia. A general worldwide increase since the 1970s in<unk> s of the arms, hands, neck, and shoulder has been attributed to the widespread use in the workplace of keyboard entry devices, such as typewriters and computers, which require long periods of<unk>  motions in a fixed posture. Extreme temperatures have also been reported as risk factor for<unk> .
