- Abstract
- The objective of the present study is to find muscle and joint forces of lower extremity while rising from a chair. The musculoskeletal system of the human lower extremity is modeled as a multibody system employing the Hill-type musculotendon model. The musculoskeletal model consists of four segments: a shank, a thigh, a pelvis and an upper body. Each segment is connected by frictionless revolute joints. Muscles of the lower extremity are simplified to seven muscles. The muscle forces are obtained by static optimization method. The objective of optimization is to find muscle excitations which minimize metabolic energy consumption while rising from a chair. The analysis results of the present study are compared with experimental results. The forces predicted by static optimization are similar to those reported in the literature.
