Outcomes
Primary outcome [1] 253111 0
The Nordic Musculoskeletal Questionnaire was administered and plantar pressure was determined using a computerized baropodometric system (FootWork). Plantar pressure values were obtained using an electronic plantar pressure plate (FootWork, AM3-IST, France), connected to a microcomputer (Pentium III). The system has 2704 active surface sensors, with a frequency of 150 Hz
