Ascent Assist; Enabling Gait Smoothing - Bioness Vector Elite Clinicians Manual

Smoothing will not decrease the active unloading below 2/3 of the original set unloading or increase it
past 50% of the patient's body weight.

Ascent Assist

This feature provides the patient with vertical lift assistance for sit-to-stand activities. During the
standing portion of the exercise, the system monitors the patient's standing speed. If the system
determines that the patient is not standing quickly enough, the unloading will be increased to assist
the patient to the standing position. Once the patient is standing, the unloading will decrease back
to the original set unloading. The maximum additional unloading provided during ascent is 2/3 of
the patient's bodyweight. This feature also provides decent control during the sitting portion of the
exercise. The system monitors the difference between the set unloading and the actual force applied
to the rope and determines if the patient is descending in a controlled manner. If the difference is
sufficiently large, the system will decrease the speed at which the Winch unspools the rope. When the
patient has reached their lowest point and is no longer descending, the Winch will unspool normally
as needed.

Enabling Gait Smoothing

Gait Smoothing can be enabled independent of DBWS and Trolley Tracking, and it will remain
enabled until it is manually disabled, even if DBWS is not enabled.
1. Select the Advanced tab. The buttons for Gait Smoothing and Ascent Assist will be displayed. See
Figure 6-7.
2. Press the Gait Smoothing button to enable it. When Gait Smoothing is enabled, the button will turn
