SAM is an S-function model of the human musculoskeletal system, developed by Marlbrook and implemented in a Simulink block.

The model contains:

539 muscles 35 joints and 36 segments

The SAM Simulink block can be incorporated into any Simulink model.

The input to SAM are Simulink signals representing forces acting on the body segments in global and local co-ordinate systems together with joint angles.

The output from SAM are muscle forces, muscle lengths and the external work of each muscle.

Graphics packages provide synchronous illustration of the muscle loading as bulging, colour coded plots during model solution and a post processing package which can display muscle loading and printed output at a single mouse click.

System requirements:

Matlab 7.5 or later

Simulink Version 7.0 or later
