Frequently Asked Questions
Here are some frequently asked questions from our customers about the ProHensor
General FAQs
1. What is the ProHensor, and how is it different from other prosthetic hooks or devices?
The ProHensor is a body-powered prosthetic terminal device that offers more control and versatility than a traditional split hook. It has a unique locking feature that lets you grip something and keep it held without needing to constantly pull on the harness. It was designed by an upper-limb amputee who wanted a tool that could handle real-world, hands-on work.
2. Is the ProHensor easy to use?
Yes. If you’ve used a body-powered prosthetic before—especially a voluntary-closing device—the learning curve is short. If you’re switching from a voluntary-opening device, there may be a bit of an adjustment at first. That said, most users find the ProHensor more intuitive overall. Your prosthetist can walk you through the basics, and most people pick it up quickly.
3. Is the ProHensor covered by insurance
In most cases, yes. It is a body-powered terminal device. Your prosthetist can help with the billing codes and paperwork.
4. Is the ProHensor heavy?
No. It’s designed to be lightweight but tough. Most users find it well-balanced and easier to wear for long periods than other options.
5. Can I switch between the ProHensor and my current prosthetic?
Yes. Many people use more than one terminal device depending on what they’re doing. The ProHensor is designed to be easy to swap in and out of your current setup.
6. Will I need to see a prosthetist to use the ProHensor
We recommend it. A prosthetist can help ensure the best fit and comfort, especially if adjustments are needed. That said, the ProHensor is user-friendly and serviceable, so with some guidance, it’s easy to maintain.
7. Is the ProHensor a good option if I’ve never used a prosthetic before?
Yes. It’s a great starting point. It’s more affordable than myoelectric options, easier to maintain, durable, and gives you solid, reliable control without a big learning curve.
8. Will it work for me if I have a short residual limb?
Most likely, yes. The ProHensor works with a variety of setups, including different residual limb lengths. Your prosthetist can help make sure it fits comfortably and functions well for your specific anatomy.
9. How long does the ProHensor last?
It’s built to last for years with regular use. It holds up well under daily wear and tear, and if anything wears out, the locking cartridge and other parts can be repaired or replaced without much downtime.

It was designed by an upper-limb amputee who wanted a tool that could handle real-world, hands-on work.
2. Can I use the ProHensor for tough tasks like yardwork, construction, or dirty environments?
Absolutely. The ProHensor was built for real-life use—including heavy-duty jobs, working with tools, gardening, or just getting dirty. It's easy to clean and strong enough to handle physical work.
3. Is the ProHensor available for both right and left arms?
Yes. The same device can be configured for either the right or left side. It works with standard wrist units, so it fits most setups.
4. Can I use the ProHensor without a harness?
The ProHensor is a body-powered device, so it does require a harness to function. However, the locking mechanism reduces how much tension you need to keep a grip, which makes it more comfortable to wear and use.
5. Can I switch between the ProHensor and my current prosthetic?
Yes. Many people use more than one terminal device depending on what they’re doing. The ProHensor is designed to be easy to swap in and out of your current setup.
6. How do I get a ProHensor? Do I go through my prosthetist or buy it myself?
You can do either. If you're already working with a prosthetist, they can order and fit it for you. If you're not currently connected to a clinic, you can reach out to us directly and we’ll help get you started.
7. What happens if it breaks or stops working?
The ProHensor is designed to be serviceable. If something isn’t working right, your prosthetist can often take care of it using standard tools. And if a part ever needs to be replaced, we’ve made the design easy to service and support. We’re here to help with any repair questions or components you might need.
8. How is the ProHensor different from a myoelectric hand?
Myoelectric hands use motors and sensors to open and close based on muscle signals. The ProHensor is mechanical—it doesn’t need batteries or chargers. It offers strong grip strength, better durability, and easy maintenance. It also gives you more direct control, especially for work or hands-on tasks.

Prosthetist FAQs
1. What are the clinical indications for prescribing the ProHensor?
The ProHensor is indicated for upper-limb amputees who require a durable, body-powered terminal device for functional daily use. It is especially well-suited for users engaged in manual work or physical tasks, and for those who may have rejected previous devices due to fatigue or lack of fine control. The ProHensor offers enhanced proprioceptive feedback, allowing for intuitive grip modulation and improved functional outcomes.
2. How does the ProHensor differ from a standard Hosmer hook?
The ProHensor features a user-actuated locking mechanism that allows the user to maintain a grip without continuous cable tension, unlike a standard voluntary-opening hook. This reduces user fatigue and improves control. The ProHensor is optimized for heavy-duty use and high-impact tasks, with grip performance rated to support up to 30 kg in lifting or sustained holding applications. It was developed with input from long-term amputee users and is designed for durability, field-serviceability, and confidence in demanding environments.
3. How does the locking mechanism work, and is it intuitive for patients?
The ProHensor’s locking mechanism is activated through a voluntary-closing motion. Once the user engages the grip, the mechanism locks in place until released through a simple, intuitive movement. Patients often report that it feels natural and reduces the strain of constant shoulder or back engagement, improving day-long comfort and control.
4. Is the ProHensor compatible with standard prosthetic components and harness systems?
Yes. The ProHensor is designed to integrate with standard wrist units, cables, and body-powered harness systems. It fits seamlessly into most existing configurations, allowing for straightforward fittings and adjustments.
5. How do I order a unit for a patient?
Units can be ordered directly through our website. Clinics and prosthetists are eligible for wholesale pricing—please contact us through our site to be added to our professional network or to request more information.
6. Can the ProHensor be adjusted or serviced in-clinic?
Yes. The ProHensor was designed to be easily maintained and adjusted using standard tools available in most prosthetic clinics. The modular locking system includes a replaceable locking cartridge, which is designed to be checked or replaced annually. This supports an ongoing care relationship between the prosthetist and patient and also provides a recurring revenue opportunity for the clinic. Most service needs can be addressed in-clinic without requiring the device to be returned to the manufacturer.
7. Do you provide trial or demo units for evaluation?
Yes. We offer demo units for prosthetic clinics interested in evaluating the ProHensor for patient trials or training. Contact us to learn more about availability and terms.
8. What training is available for patients?
We offer a variety of patient education materials, including video tutorials, printed quick-start guides, and direct support from our team. We also provide clinician-facing materials to support integration into your practice. As adoption grows, we will expand access to peer training and certified clinician resources.
9. Is there data available on patient satisfaction or outcomes?
We are collecting ongoing feedback from users and clinicians as part of our pilot programs. Preliminary results show increased prosthetic acceptance, improved functional use, and higher satisfaction rates compared to conventional split hooks. Additional data and case studies are forthcoming and will be available on our website.
10. What is the recommended HCPCS code for reimbursement?
- The ProHensor is not currently PDAC-verified under existing codes such as L6722. Using standard codes may result in insufficient reimbursement. While we cannot directly recommend a specific code, we encourage clinicians to refer to our downloadable reimbursement guide to assist in describing the device accurately, documenting medical necessity, and navigating payer-specific processes.
