Assembly Process: Place the nut into the rectangular cut out of the pen holder secure the nut and pen with the correct size screw.

Functional Use: This device is a printed writing tool that slips onto the palm and holds a pen. The person curls the fingers around it, so writing does not depend on pinch strength or fine finger control.

Relevant Occupations: Writing

Client Factors: May be relevant when grip strength or fine motor control is reduced.

Performance Skills: The palm cuff holds the pen, so the client moves the arm or wrist to write rather than gripping and manipulating a pen with the fingers.

Safety Considerations: Check the screw tightness so the pen does not shift during use.

Limitations: The cuff fit is set once printed and may require a resized version for each person. The screw can loosen. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.

Issues: None

Recommendations: Keep the pen loose in the holder and secure it tightly after determining proper positioning for the user.

Ease of use: Easy

Test results or review: The part functions as intended.
