An occupational therapist and a physiotherapist work with a patient, who had suffered a stroke, during a media presentation in the 300-square-metre therapeutic garden of the Acute Neurological Rehabilitation Unit at Lausanne University Hospital (CHUV) in Lausanne, Switzerland, August 25, 2015. Doctors at the facility say they see a significant improvement in patients with brain injuries when they are exposed to stimulation in an outdoor environment as part of their rehabilitation, and plan to share their findings on Wednesday at a seminar of neuroscience specialists.
