For a group of 24 children, 16 with spastic diplegic cerebral palsy and 8 typically developed, kinematic data were collected at the subjects self selected comfortable walking speed. From the kinematics, the work\u2014internal, external, and whole body; energy\u2014rotational and relative linear; and the angular momentum were calculated. Our findings suggest that internal work represents 53% and 40% respectively of the whole body work in gait for typically developed children and children with cerebral palsy. Analysis of the angular momentum of the whole body, and other subgroupings of body segments, revealed a relationship between increased angular momentum and increased internal work. This relationship allows one to use angular momentum to assist in determining the kinetics and kinematics of gait which contribute to increased internal work. Thus offering insight to interventions which can be applied to increase the efficiency of bipedal locomotion, by reducing internal work which has no direct contribution to center of mass motion, in both normal and pathologic populations.<\/jats:p>","DOI":"10.1123\/jab.27.2.99","type":"journal-article","created":{"date-parts":[[2016,8,10]],"date-time":"2016-08-10T13:07:12Z","timestamp":1470834432000},"page":"99-107","source":"Crossref","is-referenced-by-count":12,"title":["The
