An observational study in Movement Disorder, sponsored by National Institutes of Health Clinical Center (CC). Recruiting at 1 site in United States. Open to participants aged 1 Month to 99 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by National Institutes of Health Clinical Center (CC) · Observational
This study will collect information on the different ways people control limb and body movements. This information will be used to develop a database on normal movements and adaptive movements of people who have diseases that affect the way they move. The database will serve as a tool to improve diagnosis and treatment of patients with movement-related problems.
Volunteers from one month old to old age who have normal movement patterns or who have developed different ways to perform movement tasks may be eligible for this study. A physician or physical therapist will screen candidates to determine their strength, flexibility and range of motion of joints.
Participants will be asked to perform movements such as walking, walking up or down stairs, standing quietly or reaching for an object or using treadmill. For the test, the arms and legs are wrapped with a soft, rubber-like material to which small plastic reflective balls are attached. A piece of firm material called a shell may be attached to the rubber sleeves or other areas of the body. Then the volunteer performs the specified task several times while special cameras record the movement. These cameras will record the positions of the reflective balls during movement and may show the person s face or body. Electrical activity in the muscles also may be measured, using small metal electrodes attached to the surface of the skin with an adhesive bandage.
STUDY DESCRIPTION:
The purpose of this study is to develop a database of normative and adaptive control strategies for human motion. Volunteers will serve as subjects after they complete a neuromusculoskeletal screening exam. Subjects will be asked to perform one or more tasks related to the execution of activities of daily living such as: walking on the ground, walking on a treadmill, quiet and perturbed standing, stair ascent and descent, turning and jumping, and isolated upper and lower extremity limb movements or trunk movements. The subjects movement patterns will be recorded using a three-dimensional motion tracking system. Motion data will be analyzed using a rigid body six degree-of-freedom approach when applicable. Temporal/spatial, kinematic, kinetic, and surface electromyographic variables will be collected and calculated. When only temporal-spatial parameters are of interest, an instrumented portable walkway system may be used.
OBJECTIVES:
Primary objectives:
To develop a database of normative and adapted movement strategies for human movement. The variables calculated from the established database will be presented as mean time histories to serve as standards by which individual patient and group motion data may be compared.
ENDPOINTS:
Primary Endpoint:
The primary endpoint here is to accumulate a large database of participants with and without different neuromuscular disorders that includes multiple measures of physical function and performance, so we can begin to investigate the mechanisms underlying various disorders on either a group or individual basis.
371 studies on the registry are indexed under Movement Disorders; 102 are open to participants now.
This study's planned enrollment of 7,500 is above the median of 67 across 140 observational studies indexed under Movement Disorders.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Individuals with neuromuscular disorders and Healthy Volunteers in order to be eligible to participate in this study, must meet all of the following criteria:
Children; One month old to 17 years of age
--In the case of infants and very young children, they need to be able to imitate or perform an action on cue (e.g., reach out for a toy that is presented or take steps if placed on a treadmill) based on the parent report if the subject is a child and physician observation during history and physical examination.
EXCLUSION CRITERIA:
Individuals with neuromuscular disorders and Healthy Volunteers, who meets any of the following criteria will be excluded from participation in this study:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Normal/healthy volunteers
volunteers with impairments of the neuromusculoskeletal system.
Gait Kinematics
Strength and spasticity testing both include torque or force measurements as the primary outcomes. Balance testing typically yields the amount, velocity and direction of sway in response to different conditions or perturbations.
