Gait in Young Children With NF1

May 6, 2026 updated by: NYU Langone Health

Quantitative Gait Metrics to Assess and Predict Gross Motor Impairment in Young Children With Neurofibromatosis Type 1

The objective of this study is to develop office-based tools to quantify gait in young children with NF1 that reflect overall gross motor impairment and predict future gross motor difficulties.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

In this prospective observational study of ambulatory children less than six years old with NF1, investigators will evaluate gait speed as the fastest time to walk 10 meters and interlimb coordination derived from artificial intelligence-based pose estimates from video. Investigators will conduct office-based gait assessments with video, clinical exams, and neurodevelopmental evaluations during routine medical visits at baseline, 12 months, and 24 months at one of the largest NF1 centers in the U.S., the NYU Comprehensive Neurofibromatosis Center.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Developmental Assessment of Young Children (DAYC-2) Score
Time Frame: Baseline, 12 Months, 24 Months
Assessment of child neurodevelopmental function in which novel tasks are performed; each task is pass/fail and scored 0 or 1 point. A raw score is calculated and converted to a standard score as follows: <70 (Very Poor); 70-79 (Poor); 80-89 (Below Average); 90-110 (Average); 111-120 (Above Average); 121-130 (Superior); >130 (Very Superior); higher scores indicate greater function.
Baseline, 12 Months, 24 Months
Vineland Adaptive Behavior Scale Score
Time Frame: Baseline, 12 Months, 24 Months
Comprehensive, standardized measure of an individual's personal and social sufficiency to assist in diagnosing intellectual and developmental disabilities, autism spectrum disorder, and ADHD. The raw score is converted to a standardized score with a mean of 100 and standard deviation of 15; higher scores indicate greater daily functioning.
Baseline, 12 Months, 24 Months
10-Meter Walk Test Score
Time Frame: Baseline, 12 Months, 24 Months
Measure of gait; how quickly a participant can complete a 10-meter walk.
Baseline, 12 Months, 24 Months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
