SHOULDER

This chapter will review anatomical systems related to the shoulder. Common considerations for designers and engineers when innovating products for the shoulder will also be reviewed, along with an example student project.

SECTION 1 - ANATOMICAL SYSTEMS

Overview of the skeletal, muscular & nervous systems related to the shoulder.

SECTION 2 - DESIGN CONSIDERATIONS

When designing products that are worn around the shoulder, it is important to consider how the anatomical systems move.

SECTION 3 - KNOWLEDGE IN PRACTICE

With this information in mind, let's take a look at a product designed for the shoulder.

Design Problem:

Systems Involved:

A ballet leotard designed to support the muscles of the shoulders & lower back,​ where the promotion of better posture & form actively reduces the risk of spinal ​injury

Skeletal and muscular systems

Useful Resources:

  • Study of aesthetic needs of ballet dancers​

  • Kinesiotape trials of support structures to understand performance​

  • Interview with ballet-specific physiotherapist
