Robotic arm reaching for dumbbell

Patient Voices Shape Stronger Studies

Researchers are forging collaborations with participants — the end users of medical advances — to make their work more relevant and impactful.

In 2020, Anthony Jones had a stroke that left him with paralysis on the left side of his body. He was only 50 years old, exercised regularly and enjoyed going to the gym – activities that seemed impossible after his stroke. A few years into his physical rehab treatments, he enrolled in a clinical trial for NuroSleeve™, a robotic device that fit over his left arm, designed to enable him to regain some use of that arm to handle daily tasks and to live a fuller more independent life. The NuroSleeve improved his arm mobility, but something in particular was missing: Anthony wanted to return to his workouts involving hand weights – a task that his new robotic arm was never meant to do.  

Anthony’s experience is remarkably common. Although many assistive devices are designed with the patient in mind, researchers and designers usually make the final call about the functions that are most important or practical to restore. And from an engineering perspective, gripping a cup or a toothbrush is a very different problem to solve than gripping and lifting a ten-pound weight.

Historically, clinical trials like the one Anthony enrolled in have been conducted on people, not with them. Rarely are study participants asked about their wants and needs during a study, and even more rarely are they consulted during the planning of a new study.

But Anthony is part of a slow revolution in medical research. The terminology may vary — research that involves, engages or includes patients — but the goal is clear: People who will be end-users of a new treatment can also be true partners in how that treatment gets studied, starting from crafting research questions to designing studies and interpreting results.

As part of his clinical trial at Thomas Jefferson University and Jefferson Health, the team behind Anthony’s new powered-arm motor prosthesis is taking his goals to heart and learning and testing solutions alongside him to tweak their device to help him meet them.

The Origin of People-First Research

This novel approach to scientific inquiry in medicine is rooted in movements for disability rights across the globe, which have challenged negative framings about people living with physical and cognitive impairments in addition to fighting against oppression. Activists in the U.S. ditched their wheelchairs and crutches to crawl up the steps of the Capitol in 1990 when the American Disabilities Act had stalled in Congress. Around the same time, disability activists in South Africa coined the powerful phrase: “Nothing about us without us.”

In 2010, Congress created a trust to fund a new institute that focuses on patient education, research and outreach named PCORI, for Patient-Centered Outcomes Research Institute. As an independent government-sponsored organization, it is guided by the mantra: “Those closest to the problem are closest to the solution.”

Today, a growing number of researchers are seeking ways to engage people with lived experience and those historically underrepresented in research — throughout the clinical trial process. The approach has its challenges but is likely to yield more relevant patient outcomes. Researchers at Jefferson are leading the way, inviting people with a range of conditions, and their caregivers, to contribute to every phase of a research study and developing best practices for others to follow.

Try-and-Try-Again Studies

For neurologist and researcher Mijail Serruya, MD, PhD, patient input is his starting place, not an afterthought. He and his team, who make up the Raphael Center for Neurorestoration at Jefferson, create wearable and implantable devices for people who have lost arm or leg function as a result of stroke or injury. The NuroSleeve device that Anthony is testing is one of the team’s creations. Participants are custom-fitted with a 3D-printed splint that hugs the forearm, fingers and thumb for supported movements and is controlled by a joystick or voice command — depending on the preferences and needs of those receiving the device.

However, people with neurological impairment sometimes do express concerns about the wearable device — discomfort, different needs or goals — which might come as a surprise to researchers who assume that any kind of aid is good. Dr. Serruya’s work is iterative, and his team of doctors, occupational therapists, physical therapists and engineers continues to tweak the design of the NuroSleeve based on each user’s feedback – whether they are a 50-something person with stroke who lifts weights, or a 6-year old child with cerebral palsy who wants more function to play and engage in school. 

When Anthony began working to regain use of his left arm and hand, he started with the exercises the team had developed to help him gain confidence and comfort with the device. But he soon expressed a more challenging goal: To return to vigorous workouts. The team had never considered the demands of holding a dumbbell, Dr. Serruya says, but they went to work to make sure the device could handle a 5- or 10-pound weight.

Engineer Alessandro Napoli, PhD, says the team works using a continuous development model: “We implement one feature at a time and get feedback. Then we decide whether to keep it, ditch it or improve it.” Iterative research is anything but easy.

When developing novel devices to improve function, a whole host of issues come up. Anthony reported that his co-workers were bothered by the noise coming from his device, so the team is seeking ways to make it quieter. Another user often tangled the wires between the NuroSleeve and the controller, so the team is working to create a wireless controller.

It’s not just tinkering. Every week, Dr. Serruya’s team meets to assess the challenges. A working group includes study participants who can video-call researchers from their homes to demonstrate how the device helps — or what problems they’re still having with their daily life activities — as well as experts in rehabilitation science, neurology and engineering.

It’s a time-intensive approach but the impact is significant, especially to end-users of the device who are desperate for improved function. With the tweaks, Anthony can now use the NuroSleeve as an exercise tool. “It’s almost like having my hand back,” he says. But more than his own progress, he knows he’s a key player in a project to restore function to many individuals with stroke. “Dr. Serruya tells me: ‘Let’s try this, let’s try that. I’m willing to try it with you.’ It gives you a sense of excitement that it can be done,” says Anthony.

However, solving the engineering problems is only part of the challenge.

It's almost like having my hand back.

A Paradigm Shift

Involving people with the lived experience in research, particularly in this iterative fashion, is a paradigm shift, says MJ Mulcahey, PhD, a professor of occupational therapy in the Jefferson College of Rehabilitation Sciences. The current structures of research — the grant-review committees at funding agencies and promotion and tenure policies at research universities — do not jibe well with patient-centered approaches. The old saying, “publish or perish,” still prevails for academic scientists.

In contrast, engaging people with the lived experience early in the process, spending the time and resources to engage in collaborative discussion, “does take more time and more money; it is slower,” says Dr. Mulcahey, whose research is centered on people with spinal cord injuries, particularly children. Her team seeks to establish solid ways of measuring loss of function, which are sorely lacking. One effort to streamline the process is to create standardized questionnaires for children and their care partners that cover a range of items encompassing physical, emotional, social and school functioning.

Dr. Serruya also recognizes the barriers to doing this kind of research: “This work takes more time for back-and-forth communication and revision. We’re in an in-between space; we’re a bench-to-bedside incubator, and then we go back to the bench.”

“Although it is changing, grant reviewers historically haven’t awarded extra points for collaborating with people living with the conditions we study,” says Dr. Mulcahey.

Dr. Serruya adds that he sometimes gets feedback from grant reviewers calling his research initiatives “fishing expeditions,” with comments such as: “They’re too far-fetched, they’re too applied or practical (ironically), and they’re too high risk.”

Philanthropy has been critical to the development the NuroSleeve. Dr. Serruya has received significant support for this work through the Raphael Center from the I AM the Vine Foundation, as well as institutional funding from the Vickie and Jack Farber Institute for Neuroscience at Jefferson. This work has also earned endorsement from organizations like PCORI, which value authentic community engagement in research and are passionate about supporting it.

“We know how important this work is, but we also know it’s a real challenge for researchers who aren’t already committed and supported in authentic engagement of people affected by disease and injury,” says Dr. Mulcahey. “That’s why creating playbooks, guidelines and funding streams is so important to the success of thoughtful community engagement in research.”

Scaling Involvement to be Inclusive

In order to change the research landscape writ large, researchers who are new to engagement and patient-inclusivity, need to understand what it takes to get there. One of Dr. Mulcahey’s colleagues, Catherine V. Piersol, PhD, OTR/L, chair of the department of occupational therapy, worked with Jenny Martinez, OTD, OTR/L, a former colleague and current public health doctoral student, on guidelines to operationalize and scale community participation.

“The idea is to give researchers some best practices on how to engage stakeholders in the community,” says Dr. Piersol. “But there were no procedures in place, we had to create everything.”

The big question, Dr. Martinez says, is how to best engage and include a whole community in research, especially when clinical trials require larger numbers of patients. A child of immigrants, Dr. Martinez has seen the gap and has been the bridge for family members in her own life. She sees including community members in research as a crucial way to confront the gaps in both health care and research, by increasing minority representation in scientific studies. Her current research centers on people with dementia living in nursing facilities.

Dr. Martinez and Dr. Piersol held a meeting in Philadelphia with a broad spectrum of researchers, funders, and an advisory committee of stakeholders that included nursing home staff, patient advocates, caregivers. The primary goal, she says “was about building trust.” This meeting was a jumping off point for ongoing communication and shared-decision making between researchers and community members. The researchers evaluated these efforts and published the Stakeholder-Centric Engagement Charter to operationalize such engagement. The Charter provides clear procedures flexible enough to be customized to any research objective. It specifically addresses how to develop meaningful collaborations with communities who are often least likely to interact with research, such as those with limited English proficiency, or with distrust in the healthcare system. The Charter covers necessities such as role expectations, study governance and decision-making procedures.

“We are in the infancy of understanding the best ways to engage the community,” Dr. Mulcahey says. “It’s a radical change in academic research but a necessary one that the research community is very interested in getting right.”

This past fall, Dr. Mulcahey helped get some of these ideas out to others in the field as chair of the board of trustees of the American Occupational Therapy Foundation (AOTF), for the first “Engage Summit,” designed to strengthen understanding and skills for community-engaged research. The goal of the meeting was for clinicians, scientists, academicians and community members to come together to discuss and learn about best practices and methodologies for authentic community engagement. Intentionally, a full third of the meeting’s participants identify as a person with lived experiences of disability, chronic conditions, etc.

The Jefferson researchers committed to patient engagement are big believers in the movement. And people are beginning to quantify the advantages, Dr. Mulcahey says. “Research on community-partner inclusion is showing that it takes less time to translate research findings.” That means that putting more time in up front, and including a broad spectrum of voices, ends up helping actual patients sooner, and in ways they find most beneficial.

“It does take investment to include community partners, to set up a structure, to have a coordinator,” Dr. Mulcahey says. “But it’s helping our quality of research and meeting our patients’ needs better and faster.”

Anthony, for one, agrees. The experience of working as part of a research team of bright minds to improve people’s mobility and solve individual problems both big and small has felt very meaningful. “It’s not just for the benefit of me getting better,” he says, “but helping others.”
