WristX

Individual Project

WristX is an independent project. It is a system/product design aiming to assist the rehabilitation process for people who are suffering from Carpel-tunnel Syndrome.

Researches

Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm. The condition occurs when one of the major nerves to the hand — the median nerve — is squeezed or compressed as it travels through the wrist.

High-Risk Industries and Occupation

In California, workers’ compensation insurance companies are required to electronically report to the Department of Industrial Relations all workers’ compensation claims for occupational injuries or illnesses that cause lost time beyond the day of injury or medical care beyond first aid. From these data, we are able to list the industries and occupations that will lead to higher risks of getting the Carpel Tunnel Syndrome.

Industries

The industries listed below are some common industries that have really high risks of getting the Carpel tunnel Syndrome.

Treatment Methods

Physical Rehabilitation

After finding out the general treatment methods, I started to look into the more detailed methods of physical rehabilitation of Carpel Tunnel Syndrome.

The Carpel Tunnel Syndrome rehabilitation exercise aren’t really time consuming but they should be done repetitively and  regularly. But they are not costly or difficult for patients to do.

Conclusion

Self-care

Besides doing rehabilitation exercises, patients should also be careful of their wrist postures even when they are not showing any syndrome.

Prevention

To prevent getting Carpel Tunnel Syndrome, the user’s hands need to try to stay less angled.

Interviews

After doing online researches, I interviewed some patients who have already recovered form the Carpel-tunnel syndrome. The interview mostly focused on how they got the syndrome, the experience of having it, and the rehabilitation process.

Summary

The Carpel Tunnel Syndrome can hurt the patients really much when it deteriorates.

The Carpel Tunnel Exercises have to be done consistently. Doing them occasionally will be not as helpful.

The Exercises can be repetitive and boring sometimes.

Survey

After the interviews, I made a survey with simple questions and spread it to patients that are currently trying to recover from the Carpel-tunnel syndrome. A total of 22 patients took the survey and here are some of their answers.

Concept Goal

paiban 1-05.png

By monitoring and correcting hand gesture, rectify the users’ bad habits which might lead to Carpel-tunnel Syndrome.

By monitoring wrist movements, record and showcase datas that reflect the uses’ Carpel-tunnel health.

By combining wrist exercises and interesting games, make the rehabilitation process of Carpel-tunnel Syndrome more interesting for users.
