HAND/WRIST

This chapter will review anatomical systems of the hand/wrist. Common considerations for designers and engineers when innovating products for the hand/wrist will also be reviewed, along with an example student project.

SECTION 1 - ANATOMICAL SYSTEMS

Overview of the skeletal, muscular & nervous systems related to the hand/wrist.

SECTION 2 - DESIGN CONSIDERATIONS

When designing products that are worn around the hand/wrist, 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 hand/wrist.

Design Problem:

Systems Involved:

There are no formal push gloves available in the market for elite adaptive racers. Current gloves are make-shift and ​could cause further injury and harm. How could running footwear inspire the next generation of push rim gloves to ​maximize performance and prevent overuse injuries?

Skeletal, muscular and integumentary systems

Useful Resources:

  • Examination of existing products used by athletes​

  • Athlete interviews​

  • Working with an occupational therapist or coach to understand performance needs and challenges with overuse injuries
