Low recruitment; I/E requirements did not adequately screen appropriate participants

The objective of this study is to collect baseline data from a normative population of adolescents who participate in organized "land-based" sports, that gender and age matches some of the population of patients expected to be treated at Mary Bridge Children's Therapy Services, MultiCare affiliated therapy centers, and Mary Bridge Specialty Clinics who will be seen in the Research and Movement Lab. This project will recruit 40 patients between the ages of 13-25 years old. Non-invasive measurements of movement patterns will be collected during common sport-related activities over a single data collection session.

Inclusion Criteria:

• Age between 13-25 years.
• Participate in a "land-based" organized sport in the last 1 year with intent on continued participation in the next year.
• Perform sport-related activities such as running/sprinting, cutting maneuvers, and jumping.
• Tolerate adhesive markers placed on skin and clothing.
• Willing and interested in participating.

Exclusion Criteria:

• Neuromuscular disorders such as cerebral palsy, muscular dystrophy, myotonic dystrophy, spinal muscular atrophy, peripheral neuropathy, or other generalized muscle and/or nerve issues.
• Currently undergoing treatment or receiving medication that affects movement.
• Requires ankle/knee bracing to safely perform running, sprinting, jumping activities.
• History of orthopedic surgery to lower limbs.
• In last 6 months: receiving/seeking medical treatment for injury.
• Difficulty performing sport-related activities.
• Pain that has inhibited participation in sports/daily activities in the last 3 months.

A group of 40 neurotypical and healthy adolescent subjects who participate in organized "land-based" sports will be recruited for this data collection. Adolescent subjects will be ages 13-25 with an equal number of male and female (gender assigned at birth).
