Waddell's signs are a group of physical signs, first described in a 1980 article in Spine, and named for the article's principal author, Professor Gordon Waddell (1943–2017), a Scottish Orthopedic Surgeon.[1][2] Waddell's signs may indicate non-organic or psychological component to chronic low back pain. Historically they have also been used to detect malingering in patients with back pain. While testing takes less than one minute,[2] it has been described as time-consuming and alternatives have been proposed.[3]
