Woman robbed of right arm in horrifying farming accident 20 years ago gets brain-powered bionic arm (and it's so good she can now use a screwdriver!)

Remarkable video shows a woman using a bionic arm so sensitive it can pick up a screwdriver and coins -- using just the power of her thoughts. The Swedish woman, known only as Karin, suffered a devastating farming accident 20 years ago that robbed her of her right arm. Over the last two decades she has suffered excruciating phantom limb pain, leaving her feeling like she'constantly had [her] hand in a meat grinder'. Karin also found conventional prostheses uncomfortable and unreliable. In hope of creating an alternative that can be fully attached to a stump and a provide better range of motion, a team of engineers and surgeons from Sweden, Australia, Italy and the US developed an improved prosthetic limb.
