Rehabilitation Practice and Science
The purpose of this study was to use the KINEMETIC COMMUNICATOR KIN-COM III (a computer controlled dynamometer) in the isometric mode to estabilish flexion and extension guidelines for a trunk rehabilitation exercise program.Trunk activity was assessed in 33 young normal adults without LBP history. L5 was taken as the trunk flexion / extension center and the semi-sitting erect position was used to eliminate the gravity effect. We found that the trunk flexion and extension torques were positively related to the height and weight. The Extenision: Flexion ratio was approximately 2:l(mean 2.051 + 0.315). This data may be use as a …
