What is the percentage of of phantom pain felt by lower limb amputees?
The prevalence of phantom pain in upper limb amputees is nearly 82%, and in lower limb amputees is 54%. One study found that eight days after amputation, 72 percent of patients had phantom limb pain, and six months later, 65 percent reported it. Some amputees experience continuous pain that varies in intensity or quality; others experience several bouts a day, or it may occur only once every week or two. It is often described as shooting, crushing, burning or cramping. If the pain is continuous for a long period, parts of the intact body may become sensitized, so that touching them evokes pain in the phantom limb, or phantom limb pain may accompany urination or defecation.
Sometimes only partial compliance with license agreements is the cause. For example, in 2013, the US Army settled a lawsuit with Texas-based company Apptricity, which makes software that allows the army to track their soldiers in real time. In 2004, the US Army paid US$4.5 million for a license of 500 users, while allegedly installing the software for more than 9000 users; the case was settled for US$50 million. Major anti-piracy organizations, like the BSA, conduct software licensing audits regularly to ensure full compliance.
