Visual walking challenge

Design. Preview.
Walk.

Create timed movement cues for treadmill walking. Nothing connects to the treadmill. During the challenge, the participant only follows the screen.

Standard 60

A demonstration sequence with 10 s setup, then centre, left and right cues.
Safety first. Changing position on a moving treadmill can cause a fall and serious injury. Use only with appropriate risk assessment, supervision, emergency-stop procedures and fall protection. Read Help before use.

Warm-up / setup time

Gives the participant time to step onto the treadmill, settle, and begin walking before the first cue appears.

Selected: 10 seconds

Tap a position. The controls scale cleanly on phone and desktop.

Science & safety

What this tool does

It presents timed visual instructions for voluntary position changes during treadmill walking. It does not control treadmill speed and does not currently measure whether the movement was completed.

Scientific basis

Research on walking adaptability has used visually guided stepping targets and unexpected changes in target position to study how people adjust foot placement while walking. Experiments have shifted stepping targets anteriorly, posteriorly and laterally, and other treadmill paradigms have used visual contexts to elicit obstacle avoidance, goal-directed stepping and acceleration/deceleration relative to a constant belt speed.

Important: these studies support the broader concept of visually guided walking adaptation. They do not validate this specific PoseIQ protocol or establish it as a clinical test or treatment.

Visual challenge vs mechanical perturbation training

Formal perturbation-based balance training is generally defined as repeated externally applied mechanical perturbations that trigger rapid balance-recovery responses. PoseIQ Perturb V1 does not mechanically perturb the participant. It is a programmable visual walking challenge.

Safety

A treadmill walking challenge can result in loss of balance, a fall, serious injury, or worse. Do not use merely because someone can normally walk on a treadmill.

Use only after an appropriately qualified person has assessed the participant, treadmill, environment and task. Use appropriate supervision, the treadmill emergency stop, and fall protection suitable for the person and protocol. Perturbation-training literature commonly uses well-fitted safety harnesses for large destabilising perturbations, attached to an appropriately designed and rated support system.

Stop if the participant feels unsafe, dizzy, unwell, excessively fatigued or unable to follow the task safely. This prototype is not intended for unsupervised high-fall-risk use.

Warm-up / setup time

The setup timer is simply a hands-free delay before cues begin, allowing the participant to mount the treadmill, settle, and establish comfortable walking. It is not intended as a physiological warm-up prescription.

Prototype status

This is exploratory software, not a medical device, diagnostic test, treatment or fall-risk assessment. A custom protocol is not automatically safe, validated or evidence-based. The user remains responsible for participant selection, protocol design, equipment, environment and safety.
