title: Normal pressures and reliability of the Gaitview® system in healthy adults.
abstract: BACKGROUND
  Each plantar pressure measurement system has a different accuracy and reliability, which is required to establish a range of normal values and determine the reliability.
  
  
  OBJECTIVE
  To determine normal pressures with the Gaitview(®) system and assess its reliability.
  
  
  METHODS
  Single-group repeated measures.
  
  
  METHODS
  Dynamic barefoot plantar pressure data were obtained in 30 healthy young participants. In each session, three trials were recorded by one examiner for each foot using the two-step gait initiation method, which was repeated by another examiner the same day. One week later, all of the procedures were repeated. Time-integral mean pressures were measured for each of eight anatomical foot regions. The foot contact time (CT) and the time-integral mean angle of the center of pressure (COP) were also measured.
  
  
  RESULTS
  The greatest time-integral mean pressures were seen under the medial and lateral heel. The mean CT was 0.9 sec for both feet, and the time-integral mean angle of the COP was 9.3° for the right foot and 6.6° for the left. The intraclass correlation coefficients (ICCs) ranged from 0.69 to 0.97, and the coefficient of variation (CoV) from 9.9 to 59.97% for all parameters.
  
  
  CONCLUSIONS
  These findings indicate that the Gaitview(®) system demonstrates good to moderate reliability.
  
  
  CONCLUSIONS
  The Gaitview(®) AFA-50 system (alFOOTs, Seoul, Republic of Korea) has been used by clinicians in Korea, but has not been investigated in an independent study. Therefore, this study established a range of normal values and determined the reliability of the Gaitview(®) AFA-50 system.
