Living with cerebral palsy is exhausting. It's not just the mobility issues or the muscle spasms that people see from the outside; it’s the constant, grinding sensory tax that comes with a nervous system that doesn't quite know how to turn down the volume. For a long time, the medical community sort of glossed over the "pain" aspect of CP in adults. They focused on the surgery, the gait, and the physical therapy. But then came the 2018 pain cerebral palsy marchand study—a pivotal moment where researchers like Solène Marchand and her colleagues finally put a spotlight on what patients had been screaming about for decades.
It changed the conversation.
If you've ever felt like your doctor was just checking your range of motion while ignoring the burning sensation in your lower back, you aren't alone. Marchand’s work in 2018 dug into the prevalence and severity of pain in adults with CP, specifically focusing on how it impacts daily life. It wasn't just another dry medical paper. It was a validation of the lived experience.
The Reality of Chronic Pain in CP
Pain isn't a side effect of cerebral palsy. For most adults, it is a primary symptom. We used to think that because CP is a "non-progressive" brain injury, the symptoms stayed static. That's a total myth. The brain injury doesn't change, but the body certainly does. It wears out faster.
The 2018 research led by Marchand highlighted that over 60% of adults with CP report chronic pain. That is a staggering number. Think about that for a second. More than half of a specific population is living in a state of constant physical distress, yet until recently, we didn't have standardized protocols to treat it.
Marchand’s study looked at a French cohort, but the ripples were felt globally. The data showed that pain locations weren't random. Most of the "2018 pain cerebral palsy marchand" findings pointed toward the lower back and the hips. This makes total sense when you consider the biomechanical stress of an altered gait. If your hips are misaligned for 30 years, something is going to give.
Why Does it Hurt So Much?
It's complicated. It's not just "sore muscles." You have to look at the intersection of spasticity, dystonia, and early-onset osteoarthritis.
When muscles are constantly tight (spasticity), they pull on the joints. This isn't a "once in a while" pull; it's a 24/7 tension. Over time, this leads to structural changes. The Marchand study was crucial because it categorized this pain not just as a physical sensation, but as something that deeply affects "quality of life" (QoL).
Honestly, the medical system is often set up to fix things that are "broken," like a bone. But chronic pain in CP is more like a "leaky faucet" that eventually floods the whole house. You can't just put a bandage on it.

The Mental Tax
Marchand’s work also touched on something many doctors hate talking about: the psychological impact.
When you're in pain, you're tired. When you're tired, your spasticity gets worse. When your spasticity gets worse, you're in more pain. It's a vicious, annoying cycle. The 2018 data suggested that pain interference—meaning how much the pain stops you from doing your job or seeing friends—was a better predictor of depression than the actual severity of the physical disability itself.
That is huge.
It means a person who can walk might be "suffering" more than someone who uses a power chair, simply because their pain levels are unmanaged. We've spent so long obsessing over "walking" as the ultimate goal for CP patients, but Marchand basically said, "Hey, maybe let's focus on making sure they don't hurt all the time first."
What 2018 Pain Cerebral Palsy Marchand Taught the Medical Field
Before this study and others in that era, pain was often treated with "take some ibuprofen and do more stretches." Marchand’s findings helped push for a multidisciplinary approach.
We now know that we need:
- Physical medicine and rehabilitation (PM&R) specialists who actually understand adult CP.
- Pain management techniques that go beyond opioids, which often don't even work for neurological pain.
- Better screening.
You’d be surprised how many adults with CP go to a GP and aren't even asked about their pain levels. The 2018 research emphasized that clinicians need to use specific tools, like the Brief Pain Inventory, tailored for the CP population. It’s not enough to ask, "Does it hurt?" You have to ask, "How is the pain stopping you from living?"
The Gap in Adult Care
One of the most frustrating things about being an adult with CP is the "cliff" of care. You get all the support in the world until you turn 18 or 21, and then... nothing. You're expected to navigate a healthcare system designed for "typical" adults or the elderly.

Marchand’s 2018 study was a wake-up call regarding this gap. It showed that pain actually tends to increase as patients move into their 30s and 40s. While most people start feeling "old" in their 50s, the "CP clock" runs faster. Marchand’s data helped provide the evidence needed to advocate for specialized adult CP clinics.
Addressing the Skepticism
There’s always a bit of pushback. Some critics at the time argued that the pain reported in the Marchand study was subjective. Well, of course it's subjective. All pain is. But when you have a massive cohort of patients all reporting the same issues in the same areas (hips, back, neck), it’s no longer an anecdote. It’s a trend.
The study also had to account for the different types of CP. Pain in someone with GMFCS Level I (who walks without aids) looks very different from someone at Level V. Marchand was careful to look at how pain manifests across these levels. Surprisingly, the prevalence of pain remains high across the board. Just because someone "looks" like they move well doesn't mean they aren't dealing with a 7/10 pain level every single day.
Practical Strategies for Managing CP Pain
If you're looking at the 2018 pain cerebral palsy marchand research because you or a loved one is struggling, the takeaways aren't just academic. They're practical.
First, realize that "powering through" is usually a bad idea. In CP, pain often signals that a compensatory movement is finally failing. If you're limping to protect a sore hip, you're probably just going to ruin your lower back next.
Second, the study supports the idea of "pacing." It sounds like a buzzword, but it's about managing your "spoons." If you know a big event is coming up, you have to factor in the "pain cost." Marchand’s research validates that this isn't "laziness"—it’s a necessary medical management strategy for a hyper-reactive nervous system.
The Role of Medication and Intervention
We've moved past simple muscle relaxants. Post-2018, there's been more interest in:
- Baclofen Pumps: For severe spasticity that oral meds can't touch.
- Botox Injections: Not for wrinkles, but to temporarily paralyze the specific muscles causing the most pain.
- Cannabinoids: While Marchand didn't focus on this, the 2018 era saw a massive spike in CP patients using CBD and THC for nerve pain, often with better results than traditional meds.
The 2018 pain cerebral palsy marchand study basically acted as the "permission slip" for doctors to start taking these alternative and intensive treatments more seriously for the adult population.

The Long-Term Impact of Marchand's Work
Where are we now? Since 2018, the medical community has gotten slightly better, but we’re not there yet. Marchand's work is still cited in almost every major paper regarding adult CP and pain. It remains a foundational text for why we need "Aging with CP" initiatives.
It also highlighted that we can't treat the body in silos. You can't treat the "orthopedic" pain without looking at the "neurological" spasticity. They are two sides of the same coin.
If you're reading this and feeling frustrated by your own pain management, use this research as leverage. Tell your doctor about the Marchand findings. Explain that 60% of your peers are in the same boat. It's a way to move the conversation from "I'm tired" to "I have a recognized medical condition that requires a specific pain management protocol."
Looking Forward
We need more studies like the 2018 pain cerebral palsy marchand one, but with even larger, more diverse groups. We need to know how pain changes for women with CP during menopause. We need to know how it affects people in different socioeconomic brackets who might not have access to regular hydrotherapy or massage.
Marchand opened the door. Now we have to walk through it.
The most important thing to remember is that pain in CP is not "just how it is." It's something that can—and should—be managed. You don't have to just sit there and take it.
Actionable Steps for Pain Management
If you're dealing with the types of issues highlighted in the 2018 research, here is how you can actually use that info:
- Audit Your Equipment: Is your wheelchair or walker actually fitted for your 2026 body, or are you using settings from five years ago? Poorly fitted equipment is a leading cause of the back pain Marchand identified.
- Seek a PM&R Specialist: Stop seeing a general orthopedist who mostly does knee replacements for athletes. Find a Physical Medicine and Rehabilitation doctor who specializes in neuro-disabilities.
- Log the Pain: Use an app or a notebook. Don't just say "it hurts." Track when, where, and what kind of pain (burning, dull, sharp). This data is exactly what Marchand used to prove the severity of the issue.
- Request a SARA (Spasticity, Ataxia, and Rigidity Assessment): Ask for a formal evaluation of your muscle tone. Often, the "pain" is actually "tension" that can be treated.
- Prioritize Sleep Hygiene: Pain and sleep are linked in a "death spiral." Addressing sleep apnea or using weighted blankets can sometimes lower the neurological "noise" that contributes to pain.
The 2018 pain cerebral palsy marchand study was a milestone because it moved CP from a "pediatric mobility" issue to an "adult quality of life" issue. It's a shift that was long overdue, and it continues to shape how we advocate for better care today. Use this knowledge to be your own best advocate. You know your body better than any research paper ever could, but it sure helps to have the data on your side.
