When Oliver Sacks, a physician by profession, injured his leg while climbing a mountain, he found himself in an unusual position - that of patient. The injury itself was severe, but straightforward to fix; the psychological effects, however, were far less easy to predict, explain, or resolve: Sacks experienced paralysis and an inability to perceive his leg as his own, instead seeing it as some kind of alien and inanimate object, over which he had no control.

A Leg to Stand On is both an account of Sacks’s ordeal and subsequent recovery, and an exploration of the ways in which mind and body are inextricably linked.
