XP1 Balance Assessment

The Balance Assessment is designed to evaluate your static balance, stability, and body control using a series of standing balance tasks. This assessment helps identify strengths, asymmetries, and opportunities to improve balance and movement control over time.

Estimated Time: Approximately 5 minutes the first time and 3 minutes thereafter.

INTRODUCTION

This Balance Assessment is appropriate for most users who can safely stand and balance without assistance. Tasks include standing on one leg and, for increased challenge, closing the eyes while maintaining balance. Any task that cannot be safely performed should be skipped.

The Balance Assessment Evaluates:

• Stillness while standing
• Duration of maintained balance
• Body shift forward/backward and side-to-side
• Differences between left and right sides during single-leg stance

Results provide personalized balance insights and progress tracking.

BEFORE BEGINNING & SAFETY

Do not perform the assessment if:

• The ability to stand unassisted is lacking
• There is a recent history of falls or a feeling of being unsafe when balancing
• A medical professional has advised against balance testing
• Conditions exist that might lead to loss of balance (e.g., Acute Vestibular Crisis, Severe Orthostatic Hypotension, Acute Injury or Post-Op Status Neurological Instability, Decompensated Heart Failure, Cognitive Impairment)

Consult a medical provider with any questions. If you feel unstable or unsafe at any point, stop the assessment immediately. Safety First: Skipping any task, especially single-leg or eyes-closed variations, is encouraged if safe performance is a concern.

Setup & Technique

XP1 SETUP 

• Stand centered front-to-back on the left force plate only, keeping both feet at least 1 inch away from the plate edges
• Unclip front and rear cables from any accessory and ensure they are fully retracted into the deck position.

On-screen guidance will help ensure proper positioning for your device.

ASSESSMENT FLOW & TASKS

You will be guided through a series of six balance tasks. Each task includes brief on-screen instructions and a short countdown before starting.

Task Progression:

1. Both-Leg Stance Eyes Open
2. Both-Leg Stance Eyes Closed
3. Single-Leg Stance Eyes Open (Left & Right)
4. Single-Leg Stance Eyes Closed (Left & Right)

Eyes-closed tasks are more challenging and may only be appropriate if you demonstrate sufficient stability during eyes-open tasks.

UNDERSTANDING RESULTS

After completing the assessment, you will see a summary of your balance performance.  Results are always available for review. Each task is scored on a 0–100 scale, with higher scores indicating stronger control. Scores are based on multiple measurements captured during the trial, including steadiness, movement control, and how long the position is maintained.

Note: If a task is skipped, a score of 0 is recorded and included in the overall assessment results.

Assessment Summary Scores

At the end of the assessment, you will receive two primary scores:

• Average Score: Represents the average of all completed trial scores (including skipped tasks) and reflects overall balance performance.

   

• Symmetry Score: Reflects how evenly balanced your left and right sides are during single-leg tasks. Higher scores indicate greater left-to-right symmetry. It is calculated by comparing the difference between left and right leg performance, with a smaller difference between sides resulting in a higher symmetry score.

Together, these scores provide insight into both your overall balance ability and side-to-side control. Higher average and symmetry scores generally indicate stronger and more controlled balance performance.
