Foot drop, or drop foot, is a difficulty in lifting the front part of the foot, which can make walking challenging. This study analyzes the gait of a 52-year-old patient diagnosed with drop foot caused by a surgery at the lumbar level. Baropodometric tests were conducted with and without the cane as assistive device to identify significant changes in load distribution and stabilometry. An inertial sensor was also used to get information about gait quality, symmetry and propulsion index, and pelvic angles when said aid was implemented in order to confirm its influence on the patient's gait. In obtained results with use of cane, there is found an improvement of 34.4% in lateral distribution of loads and 4.7% in quality index of left foot gait, this confirms positive influence that has this device to rehabilitation process of the patient.
