Strengths & Limitations
Strengths
- +Comprehensive review of a significant number of devices.
- +Categorization of devices based on multiple technical and functional aspects.
Limitations
This review is based on published data and may not capture all nuances of device performance or user feedback.
Reliability & validity
The reliability of the findings depends on the accuracy and completeness of the reviewed literature. Validity is supported by the systematic approach to device categorization.
Think critically
To what extent does the 'softness' of an exoskeleton compromise its ability to provide significant assistive force or torque?
Design Principles
"Kinematic compliance and ergonomic integration are paramount for effective wearable assistive devices."
For designers developing assistive or rehabilitative devices, the choice of materials and construction significantly impacts user acceptance and functional efficacy. Prioritizing soft, compliant designs can lead to better integration with the human body, reducing the risk of injury and improving the user's experience during operation.
What This Means for Your Design
Most wrist support devices are made of soft materials because they bend and move better with your wrist and are safer and more comfortable to wear.

Paragraph starter
The review by Pitzalis et al. (2023) highlights that over half of wearable wrist exoskeletons are designed using soft materials to enhance kinematic compliance, ergonomics, and safety. This indicates a strong design trend towards prioritizing user comfort and natural movement, which is a crucial consideration for any assistive or rehabilitative device.
