Table 2 Protocol of experimental trials
Trial | Conditions |
|---|---|
No Cue Walk (NCW) | Normal walk in a straight line without any assistance/cue Subject maintains self-preferred walking speed Operator calculates the normal gait speed of the subject |
Tactile Cue Walk (TCW) | Walk with only VFD’s tactile cue Subject maintains self-preferred walking speed Operator calculates the gait speed |
Kinesthetic Cue Walk (KCW + 0%, KCW + 20%, KCW + 40%) | Walk with only HCD’s kinesthetic cue Speed is set to normal gait speed + 0%, + 20% and + 40% in separate trials |
Integrated Cue Walk (ICW + 0%, ICW + 20%, ICW + 40%) | Walk with both VFD’s tactile cue and HCD’s kinesthetic cue Speed is set to normal gait speed + 0%, + 20% and + 40% in separate trials |
