Analysis of vertical ground reaction force variables by Foot scan in hemiplegic patients

Material and methods Twenty patients with hemiplegia due to vascular causes underwent gait analysis (by the F-Scan system). All patients had steady neurological status and were able to gait independently more than 8 m. The following vertical ground reaction force variables were measured: the first peak force during early stance(F1Y) and the percent stance at which it occurred(F1X); the second peak force evident through push-off(F2Y) and the percent stance that it occurred(F2X); loading rate, push-off rate, vertical force impulse, and stance time. Comparison of the GFR records was performed between hemiplegic patients and healthy control group and affected and unaffected limbs of hemiplegics. The group control consisted of 20 healthy volunteer subjects.
