Database of Normative and Adapted Movement Strategies for Human Motion

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.
