Human Movement Database

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.

• INCLUSION CRITERIA:

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.

• Adults; 18 years 99 years
• In good general health as evidenced by medical history or diagnosed with impairment of neuromusculoskeletal system
• Stated willingness to comply with all study procedures and availability for the duration of the study
• Provision of signed and dated informed consent form
• For those participants older than 5 years of age who have an abnormal gait pattern when walking as a result of a central nervous system injury, Dr. Alter will ask them or their guardian about their seizure history

Exclusion criteria

Individuals with neuromuscular disorders and Healthy Volunteers, who meets any of the following criteria will be excluded from participation in this study:

• Individuals with pacemakers
• Pregnancy
• Adults unable to provide informed consent
