Ryleah Geisner, 8, laughs as she looks at a computer image of herself walking with reflective and surface EMG sensors attached to her body in the Center for Gait and Movement Analysis lab at Children's Hospital Colorado in Aurora, Colorado, U.S., February 9, 2017 with lab engineer Kayla Burnim (R.) Ryleah has cerebral palsy, a congenital disorder of movement, muscle tone, or posture. The lab was using 3-D motion capture technology to analyze Ryleah's body movement and muscle activity while walking and that data will then be used to formulate a treatment plan for her. In the background is Ryleah's grandmother Sandy Geisner. Picture taken on February 9, 2017. REUTERS/Rick Wilking
