PROBLEM TO BE SOLVED: To measure a handrail dependent load in performing gait training using a gait training device, and feedback the handrail dependent load to a trainee visually.SOLUTION: A gait training system 10 includes a walking data detection unit 20 and a walking data display unit 30. The walking data detection unit 20 includes a pair of sensor units 60L and 60R provided to a right and left pair of grip parts 54L and 54R, and a communication unit 70. The walking data display unit 30 includes a display device 80 and a data processing device 90. The data processing device 90 includes a data transmission and reception part 100, a storage part 110, a data analysis part 120, and an image creation part 130. The data analysis part 120 reads out each data (force detection signal) stored in the storage part 110, and analyzes data of the trainee P in gait training. The image creation part 130 creates image data of a handrail dependent load displayed in the display device 80 from the analysis result.
