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 Skeletal System

Hand/Wrist Muscular System
LaBat & Ryan, Figure 7.3
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.

Wrist Range of Motion: Flexion, Extension, Radial & Ulnar Deviation with Muscles

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
