Trevor Grimbleby, CPO, on Innovation, Patient Outcomes, and the Limber UniLeg
At Limber Prosthetics, we value our partnerships with clinicians who embrace innovation and are committed to improving outcomes for individuals with limb loss. This month’s Clinic Spotlight highlights The AMP Group led by Founder and CPO, Trevor Grimbleby. Serving California’s Central Valley, The AMP Group provides top-notch prosthetic solutions that restore mobility and independence for amputees at every level, sharing Limber’s mission of advancing prosthetics for good.
A Career Built on Restoring Mobility
Originally preparing for a career in physical therapy, Trevor shifted to O&P after gaining exposure to the field during graduate studies. What struck him was the life-changing impact prosthetic care could have on patients. “It’s insanely rewarding to be able to get somebody to walk again,” he explained. Now with almost nine years in the industry, Trevor continues to focus on improving the quality of life for patients by incorporating the adoption of new groundbreaking devices in the industry like the Limber UniLeg.
Discovering the UniLeg: Meeting a Clinical Need
During his time at a large national clinic, Trevor repeatedly encountered situations where patients needed a secondary prosthesis. “Every time I worked with a below-knee amputee, I always tried to create a backup leg,” he recalled. Whether for showering, traveling, or enjoying time outdoors with family, a secondary prosthesis provided patients with convenience and peace of mind.
Living and practicing in California, where beaches, lakes, and outdoor activities are central to many patients’ lifestyles, Trevor saw the need for a prosthesis that could handle water, sand, and other challenging environments. Traditional prostheses were often not well suited for these situations, leaving patients without practical solutions.
When Trevor first learned about the Limber UniLeg, its fully 3D-printed structure immediately stood out. “We’ve all seen companies create 3D-printed covers, but to see an entire prosthesis produced this way was fascinating,” he said. As he prepared to open his own practice, it was a clear decision to make the UniLeg part of his clinical offerings. “The ability to provide a legitimate, affordable backup leg was something I felt was overlooked in the industry,” Trevor added.
Clinical Experience and Digital Workflow
Trevor emphasized that one of the most valuable aspects of working with Limber has been the accessibility of the team. “Working with every member of the Limber Team, it’s clear they care about their clinicians and patients,” he said.
The Limber Clinical App also played an important role in streamlining the workflow at The AMP Group. By simplifying the scan-and-order process and reducing the time needed to create a functional prosthesis, the app allowed Trevor and his team to devote more time to patient care. Combined with the UniLeg’s quick turnaround and affordability, the system has become an efficient and practical addition to his practice.
“The UniLeg doesn’t compare to anything else—it’s an industry shaker,” Trevor said. “Like many prosthetists, I had hesitations about durability, but it’s proven to be the real thing.”
Patient Feedback and Real-World Success
Trevor’s first UniLeg fitting was with a longtime friend and amputee. He wanted honest feedback before fully endorsing the device. “I told him, ‘You’re going to be my guinea pig on this,’” he recalled. After just two and a half weeks of use, the patient had completely abandoned his previous prosthesis.
His response was immediate and enthusiastic. “His first reaction was, ‘I feel like I have my foot and ankle again,’” Trevor explained. Today, the patient uses the UniLeg daily—not just for water or recreational use. “I never told him to wear it all the time, but the device speaks for itself,” Trevor added.
This testimony underscores the UniLeg’s potential to exceed expectations and provide patients with a level of comfort and functionality that translates into real quality-of-life improvements. Patients also appreciate the prosthesis’s lightweight design, ease of use, and adaptability to environments that would typically challenge traditional devices.
Broad Applications for Different Patients
Initially, Trevor envisioned the UniLeg as best suited for highly active K3 users who could benefit from its durability and energy return. However, through conversations with colleagues and his own clinical experience, he has come to see the UniLeg’s versatility.
“It can be a lightweight option for older patients who are becoming frailer and struggling with heavier prostheses, or it can be a versatile, everyday device for younger, more active users,” he said. “There’s really an application for any below-knee prosthetic user.”
This broad applicability makes the UniLeg a unique option in the prosthetic landscape, where many devices are designed with narrower patient profiles in mind.
Looking Ahead: The Future of 3D Printing in O&P
Trevor sees 3D printing and digital workflows as an inevitable part of the future of orthotics and prosthetics. “It’s advantageous for diagnostic fittings, quick turnarounds, and reducing reliance on plaster and traditional fabrication methods,”he explained. From cost savings on materials to reductions in labor and equipment needs, the shift to digital promises greater efficiency for clinics and improved access for patients.
When asked if he would recommend the UniLeg to other clinicians, Trevor was unequivocal: “Wholeheartedly. When my patients are thrilled, what else can you ask for?”
At The AMP Group, the Limber UniLeg has become more than just a backup leg—it’s a versatile, lightweight, and durable solution that meets a wide range of patient needs. Trevor’s early adoption of the UniLeg reflects his dedication to improving patient care and embracing technologies that redefine what prosthetic devices can achieve.
