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.

Hand/Wrist Muscular System

Hand/Wrist Nervous System (median, radial & ulnar nerves)
Modified from LaBat & Ryan, Figure 7.10
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
