Office Kit Adapted for People With Parkinson's – Fine Motor Technical Aid

This project presents a technical aid designed to support individuals with Parkinson’s disease who experience difficulties with fine motor skills. Technical aids are any external tools (devices, equipment, instruments, or software) aimed at maintaining or improving a person’s independence and overall well-being. They also help prevent further impairments or secondary conditions.

Parkinson’s is a brain disorder that leads to movement-related challenges such as tremors, stiffness, and loss of coordination. Over time, these symptoms can severely affect daily activities, especially those requiring manual dexterity and precise finger movements.

This adapted office kit aims to reduce those barriers, making everyday administrative tasks more accessible and manageable for people affected by Parkinson’s.

To address these challenges, this adapted office kit includes:

1. A pen with a non-slip grip,
2. Modified scissors for easier handling, and
3. A paper clip holder for better document control.

For the Non-Slip Grip Pen Adapter:

1. EVA foam
2. Velcro strap
3. TPU filament
4. 3D printer

For the Adapted Scissors:

1. Regular scissors
2. PLA filament
3. 3D printer

For the Paper Clip Holder:

1. Acrylic sheet
2. TPU filament
3. Spring-loaded clip
4. 3D printer
5. Laser cutting

1.Download the files and make some adjustments if needed.

The adapter was designed in SolidWorks and consists of three interlocking parts:

1. Part A:
2. Part B:
3. Part C:

Grip Structure – This component is designed to be placed over the user’s hand, providing a stable support point. It features two openings that allow adjustable Velcro straps to pass through, ensuring the device stays firmly in place during writing tasks and minimizing involuntary movements.

Flexible Mounting Arm (Connector) – A curved, flexible element that connects the grip structure to the pen holder. It is designed to support the index finger, providing additional stability and control. The arm includes an extension that secures the finger, helping to maintain a controlled and comfortable writing position.

Wide Pen Holder – A cylindrical clamp with a larger-than-standard diameter, designed to securely hold a pen or pencil without requiring fine gripping. This allows the user to write without pinching the pen, which can be difficult for individuals with Parkinson’s disease.

2.3D Print the parts

Use a Bambu Lab printer with TPU filament and --% infill.

3.Assembly

1.Prepare the base:

Cut the acrylic board in the laser cutter, you can download the DXF here:

2.Model and print the clip holder:

In SolidWorks, model a base mount that holds a standard binder clip mechanism. Print this support structure using TPU for rigidity.

3.Assemble:

Attach the metal binder clip to the 3D printed support using screws. Mount the whole assembly onto the acrylic base with strong glue or screws.
