For many of us, grasping a tool or utensil is second nature. But for individuals with hand weakness or limited dexterity, everyday tasks can be frustrating and challenging. That’s where DIY adaptations for gripping and grasping come in, offering a helping hand to regain independence and confidence with daily activities.
If you want to learn more, please visit our website.
Do-it-yourself (DIY) grip and grasp adaptations are customized tools and devices designed to assist individuals with holding objects more effectively. These aids are used to enhance the stability and comfort of a person’s grip, making daily activities more accessible for individuals with limited hand strength or dexterity. Grip and grasp aids come in various forms, including specialized handles, straps, adaptive tools, and ergonomic devices, tailored to meet the specific needs of the intended user.

It may be helpful to understand some of the basic biomechanical and sensory principles that apply to grip and grasp aids. Here’s a user-friendly explanation of the principles applied:
Leverage: Imagine using a wrench. The longer the handle, the easier it is to turn a tight bolt. In the same way, grip aids often provide extended handles or surfaces, allowing you to use leverage to your advantage. This minimizes the force your muscles need to exert.
Friction: The amount of grip you have depends on the friction between your hand and the object you’re holding. Some grip aids have textured surfaces that increase friction, making it easier for you to maintain hold without excessive squeezing.
Joint Alignment: Our joints work most efficiently when they’re aligned properly. Grip aids are designed to promote natural alignment of your hand and wrist, reducing stress on the joints and making it more comfortable for you to hold onto objects.

Ergonomics: Ergonomics is about designing tools and devices to fit the human body’s natural shape and movements. Grip aids are often designed with ergonomic principles in mind, mimicking the natural shape of the hand to distribute forces evenly and reduce strain.
Sensory Feedback: Grip and grasp aids may incorporate features that enhance tactile feedback to the user. This feedback helps individuals better sense their grip strength and adjust their hold accordingly.
Surface Area: The biomechanical principle of surface area influences the distribution of force across a larger area. A larger surface area provides more secure grip, allowing individuals with limited hand strength or dexterity to manipulate objects better.
Many of the materials needed for DIY grip and grasp aids can be found around your home, workplace, or workshop. Here’s a sample list to get started:
Rubber bands
Foam tubing
Non-slip materials like shelf liner or Dycem Non-Slip
Specialty tapes with properties like padding or friction like Cat Tongue
Self-adhering bandage wrap like Coban.
Cloth elastic bandage wrap
Moldable materials like thermoplastic materials or clay for custom grips
Grip dips and coatings
Heat shrink tubing
Built-up handles are thicker, easier-to-grip attachments added to the handles of everyday items like utensils, writing tools, toothbrushes, and gardening tools. They come in various materials, shapes, and sizes, catering to different needs and preferences. Some of the common biomechanical principles applied to built up handles includes increased surface area, ergonomics, joint alignment, and sensory feedback. You can wrap several layers of tapes or bandages, add foam grip tubing, or create custom hand grips with moldable materials to build up handles. The Rehab Store has foam tubing that can be cut to the desired length. A top choice for bandage wrap to build up handles is Coban, which is available in several colors.
Weighted handles can improve stability and joint position sense, using the principles of sensory feedback. Adding weight may be helpful for tremors or sensory issues. Adding heavy objects like metal or building up the handle with moldable materials like air-dry clay can achieve the desired weight characteristics. Many weighted handles have combination features like built up surfaces, tactile elements, and anti-slip features as well.
Anti-slip and textured materials use principles of friction to stabilize the hand. Sweaty palms and weak hands gain an advantage when the skin “sticks” to the grasp aid better. Depending on the size and shape of the friction enhancement features, the principles of leverage may be applied too. See our post on Stabilizing Materials for Daily Living Aids and Items for several material ideas!
Cushioned handles support hand function by absorbing shock, damping vibration, and distributing pressure evenly. They conform to hand contours, provide a more comfortable grip, and decrease hand fatigue during extended use. Individuals with hand pain, arthritis, tendonitis, and people with hand injuries are great candidates for cushioned handles. The principles of ergonomics, sensory feedback, surface area, and joint alignment apply best to DIY cushioned handles. Great materials to use include foam padding, elastic fabric bandage wraps, and self-adhering bandage wrap.
Custom-molded hand grips support hand function by conforming to the user’s hand contours, enhancing comfort and reducing the effort required for a secure grip. They offer joint protection by promoting proper alignment and minimizing stress on hand joints. People with arthritis, joint deformities, hand injuries, hand pain, and hand weakness can particularly benefit from custom molded handles. Similar to cushioned handles, the principles of ergonomics, sensory feedback, surface area, leverage, and joint alignment apply for cushioned handles.
Some custom molded handles can be created by assistive technology novices using product like air dry molding materials like Sugru and air cry clay. Other moldable materials like thermoplastic beads and sheets require more experience and enhanced safety precautions. Our post on Moldable Materials for DIY Assistive Technology Projects covers many material options and ideas.
Most custom cuffs and holders are for advanced DIYers. They can be made out of materials like nylon webbing, hook and loop straps, D-rings, and splinting material. See our tutorials for ideas! Cuffs and holders offer distinct advantages for people with little to no grasp strength because they wrap around the hand and prevent items from dropping. Biomechanical principles of leverage, surface area, ergonomics, and joint alignment apply best when designing custom cuffs and holders for people with very weak to absent hand strength.
In the realm of DIY assistive technology, aids to improve gripping and grasping opens doors for individuals facing challenges with hand weakness, injuries, or limited dexterity. The basic biomechanical and sensory principles of leverage, surface area, ergonomics, joint alignment, sensory feedback, and friction play pivotal roles in enhancing the effectiveness of these tools. By applying these principles with DIY friendly materials, you can empower yourself or others to regain independence and confidence in their daily activities.

I do love the look and feel of my RO Operator, but because I have wide palms and short stubby fingers, I can't quite reach the slide stop or even the mag release button without turning the firearm slightly to reach it. Slightly thinner grips would help, but I'm clueless on what brands people like, etc. Kinda hate to lose the logo (goofy, I know) but handling is more important.What kind of look are you going for ?
I'd rather ask my peers in the forum instead of googling this one, lol. Thanks!

What kind of look are you going for ?That probably would have been good info for me to include, lol. I guess I'm not sure, I love the cocobolo look, but I did find these on the SA site:
Traditional wood ? More modern ? Fake ivory ?
I have some grips from this place on a Hi power and like them.Thanks! I'm-a-goin' window shopping!
They do ’s as well in a bunch of styles

I actually picked up a set of these. They're regular size, but with the thumb cutout for easier access to the slide/mag release. G10 style grips.My stubby thumb needs that aggressive thumb cutout... are these VZ Grips?

They also make some with a more aggressive thumb cutout as well - see the below picture.

My stubby thumb needs that aggressive thumb cutout... are these VZ Grips?Amazon links here - there are a few brands with slightly different grip patterns and colors. Brands I found are Guuun, Cool Hand and Bestwest. I'm sure there are more. I didn't see any VZ ones with the larger cutout.
