IRB Number: 11195

May 24, 2012

Institutional Review Board, Hospital for Special Surgery

The safety of our participants is our top priority. The trial/study is approved and periodically reviewed by the Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial or research study, the investigator will explain the purpose of the trial/study, its expected benefits, any possible risks or side effects, and what your role will be. If you want to join the trial/study, you must sign informed consent documents. You can leave a trial/study at any time without penalty.

This study seeks to determine normative three-dimensional scapular kinematics of asymptomatic normal shoulders in individuals over the age of 50 years. 20 individuals with pain free and full range of motion will be asked to participate in the study which involves: shoulder strength testing, 3D motion analysis of the upper extremities, and an ultrasound examination of the shoulder. The study will investigate possible differences between healthy controls and asymptomatic tears that are expected to be found within the participants. The data will be used as a reference for future investigation of shoulder pathologies

Inclusion/Exclusion Criteria

Inclusion Criteria
1) Females and males >50 years old
2) Pain free and full range of shoulder motion
3) American Shoulder and Elbow Surgeons (ASES) Self Assessment Score > 90
4) Able to complete the Simple Shoulder Test (SST) 

Exclusion Criteria
1) Any history of shoulder pathology
2) Allergy to double sided marker tape (needed to affix the motion markers to the body).
