Exercise 8: Backwards Heel to Toe/Tandem Walking in the Solo-Step

Setup: Fit the patient into the Solo-Step harness and connect the lanyard to the trolley on the overhead track. Position the patient at one end of the track, facing away from the direction of travel. A line of tape along the floor beneath the track can serve as a useful visual guide for foot placement. Adjust the lanyard length to allow natural upright movement while ensuring that the system engages immediately if balance is lost. The patient may extend their arms out to the sides to assist with balance throughout the exercise.

Starting Position: Have the patient stand tall at the end of the track, facing away from the direction they will travel, with feet together and core lightly engaged. Instruct the patient to keep their head up and their gaze forward. Resist the urge to look down at their feet or turn to look behind. Take a moment to feel secure in the harness before initiating the first step.

The Exercise:

1. Cue the patient to step backward with the lead foot, placing the toes of the stepping foot directly behind the heel of the standing foot. The patient’s toes and heel should be touching or nearly touching, with both feet aligned along the same straight line.
2. Instruct the patient to transfer their weight fully onto the stepping foot before lifting the trailing foot to take the next step backward.
3. Continue walking backward in this toe-to-heel pattern along the full length of the track, maintaining an upright trunk and a forward-facing gaze throughout.
4. Encourage a slow, deliberate pace. Precise foot placement and postural control take complete priority over speed.
5. At the end of the track, have the patient pause, reestablish their balance, and return to the starting position using the same backward tandem pattern.
6. Repeat for the prescribed number of lengths or duration.

Progressions: As balance and coordination improve, the therapist can advance the exercise by increasing the pace, introducing a cognitive dual task such as counting or conversation while walking, having the patient cross their arms over their chest to remove the arm balance assist, adding a head turn or rotation during the walk to challenge the vestibular system, or progressing to an eyes-closed variation to further tax the proprioceptive and vestibular systems.
