Excerpt

This investigation is the cooperative effort of representatives of two closely related professions, Physical Education and Physical Therapy. In general, investigators studying the movement of normal persons and those interested in the movement problems of persons with neuromuscular or orthopedic impairment seem to have taken divergent paths. Nevertheless, the same basic knowledge is important to both. A clear understanding of the functioning of normal muscles is equally essential to the physical educator teaching the normal person and to the physical therapist working with the handicapped.

The complexity of this first attempt to sample muscles of the entire body during the performance of complex motor skills makes detailed analysis almost impossible. Because of this, and the fact that so many muscles act over more than one joint, other kinesiologists may make somewhat different interpretations of the data that are presented. However, it is the hope of the authors that this monograph will increase the understanding of the way in which normal muscles function together, and that it will serve as a background against which the results of more detailed investigations of single muscles or small groups of muscles will take on greater meaning, and thus expand the knowledge that can be gained from these studies. In this way, it should assist both the physical educator and the physical therapist with the solution of normal and abnormal movement problems.

This study could not have been accomplished without the cooperation of the School of Physical and Health Education, Department for Women, University of Washington and the Detroit Orthopedic Clinic, as well as an Amy Morris Homans grant from Wellesley College. The Detroit Orthopedic Clinic is a nonprofit agency supported by the United Foundation of Detroit. The Research and Education Department of this agency is supported only by special grant funds. These were received from the Sigma Gamma Foundation, Sigma Gamma Association, Omega Eta Tau, D. M. Ferry, Jr. Trustee Corporation, Kresge Foundation, Ford Motor Company Fund, and Eph Foundation.

We express sincere appreciation to Miss M. Genevieve Blakeley, Executive Director of the Detroit Orthopedic Clinic for making this study possible; to Miss Elizabeth Culver, who participated as the subject; to Mrs.
