title: Evaluation of Undergraduate Physical Therapy Students' Comprehension of Maitland's Grades (I-IV) for Posterior Mobilization of the Glenohumeral Joint.
abstract: In this study, the instruction of undergraduate students in Maitland's grades (I-IV) for posterior glenohumeral mobilization as a valid instructional goal was investigated. Undergraduate students were instructed in Maitland's mobilization grades I-IV at various joints before the experimentation. Students selected were mobilized by the instructor. A random assignment of grades was given to the instructor before mobilization. The mobilization subject secretly identified the grade as the mobilization was being videotaped. The videotape was played to the class of undergraduate students who were asked to identify the grades visually. The accuracy of the student's ability to identify the assigned grades visually and kinesthetically was determined to be within the projected 90% accuracy level; therefore, the hypothesis was substantiated.J Orthop Sports Phys Ther 1980;1(4):214-221.
