Noah steps into the room, suited up in black athletic put on. Beginning at his ft and transferring as much as his neck, two graduate assistants take turns sticking small, reflective markers on him—about 50 in whole. They reinforce the markers with tape and fasten six bigger, blinking sensors to every leg. One particular person wraps the sensors in black felt whereas the opposite ties a thick band round Noah’s brow.
After they step away, Noah* rolls again his shoulders and shakes out his arms. He seems able to tackle a supervillain.
Cameras across the room file the motion of the markers as Noah walks, jumps, and stretches. A pc interprets the info right into a determine of yellow strains and blue dots, matching Noah step-for-step.
Hollywood makes use of this know-how to seize sensible human motion for CGI characters and monsters on the massive display (assume the apes in Planet of the Apes or Gollum from The Lord of the Rings). However within the Neuromusculoskeletal Health Lab on the College of Georgia, this knowledge might assist enhance lives.
Noah was born with cerebral palsy (CP), which impacts his muscle groups and coordination. His proper leg is extra inflexible than his left, and his proper hand is weaker. However you won’t comprehend it simply by taking a look at him. His CP is delicate, which suggests he can do issues like play baseball, his favourite sport.
“He’s an athlete at coronary heart,” says his mom, Cindy.*
Noah’s first phrase was “ball.” As a toddler, he may sit by way of a whole Washington Nationals sport, and he began enjoying T-ball as quickly as he was sufficiently old.
Noah’s situation doesn’t stop him from operating the bases, however it does have an effect on his on a regular basis life.
“He straddles each worlds,” Cindy says. “He seems and acts like a neurotypical child, however he has to work very exhausting to take part in actions that almost all children do with out pondering.”
Noah was recognized at 2 years previous. Now 9, he’s participating in a UGA examine to check the effectiveness of a brand new therapy that, if profitable, may assist him and different kids with extra extreme types of CP.
Dwelling with Cerebral Palsy

CP impacts muscle high quality, bone well being, and motor expertise. Roughly 75% of youngsters with the situation expertise spasticity, or muscle stiffness, making it tough to maneuver. It could additionally trigger uncontrollable actions or lack of steadiness and coordination. Many kids, like Noah, expertise a mixture of those results.
Remedy choices differ as a lot because the situation does, and the prices add up. Botox injections might assist quickly calm down overactive muscle groups, and surgical procedure can right posture and misaligned joints. Bodily remedy may also assist, however extra analysis is required, Modlesky says.
“There are usually not almost sufficient individuals who may acknowledge CP and acknowledge it early sufficient the place kids can get the assist they want,” he says. “And for many who get assist, we don’t know sufficient about what the best therapy methods are.”
The scientific trial is taking steps to alter that. Forty-four kids like Noah, aged 5 to 11, go to the lab 5 instances over a 12 months. Researchers accumulate knowledge to evaluate their motion, muscle power, dexterity, steadiness, and different measures throughout periods that last as long as two days. However the examine’s major focus is another therapy: whole-body vibration remedy.
“There are preliminary research suggesting that vibration has a optimistic impact on muscle groups and on steadiness,” Modlesky says. “The main target of this examine is to take a look at a gentle vibration intervention and decide if it might enhance muscle dimension and high quality and if it might enhance steadiness, finally growing the kid’s participation in bodily exercise.”
Individuals stand on a small, sq. platform that appears like a scale. When activated, it emits virtually imperceptible vibrations that journey from the ft to the pinnacle. Electromyography sensors monitor muscle responses as contributors bend, leap, and steadiness, recording modifications over time.

Breaking it Down
That is Noah’s second go to to the lab. He’ll return twice in the summertime and once more subsequent January for his ultimate session. The household travels from out of state to participate, however for his mother, the space is greater than price it.
“Typical medical docs have been fairly dismissive as a result of his case is delicate, and he doesn’t take care of the frequent medical problems that include CP,” she says. “Having the folks at UGA as a useful resource and figuring out they’re working to enhance the lives of children like [Noah] provides us a lot hope. They perceive at a scientific stage what’s going on in his physique and have helped clarify it to me when nobody else has.”
The examine outcomes may make different therapies like whole-body vibration extra accessible and inexpensive. Within the meantime, the lab helps households study extra about how CP impacts their kids’s each day lives.
For Owais Khan, a graduate analysis assistant within the lab, that’s one of the vital vital facets of the examine.
“We’re giving them extra details about their little one’s physique capacities and skills whereas letting them discover a remedy that doesn’t require the form of monetary enter that conventional occupational or bodily remedy does.”
Initially from Mumbai, India, Khan is a skilled pediatric bodily therapist. He enrolled as a graduate pupil at UGA in 2019 to work beneath Modlesky. The multidisciplinary nature of the lab lets him and different graduate college students discover completely different analysis areas, from biomechanics to neuroimaging. The services and know-how throughout the lab are unmatched, he says.
“We’re utilizing so many alternative instruments to study CP from completely different views; the alternatives are infinite. All that’s required is a willingness to place within the work, a need to work with kids, and the initiative to take step one,” Khan says.

Each pupil within the lab—seven graduate assistants and 6 undergraduate volunteers—helps a bit of the examine, from writing knowledge evaluation applications to conducting exams. They, together with two workers members, dedicate their weekends to working with the youngsters and households within the scientific trial.
Khan discovered his area of interest in higher limb rehabilitation. He works with the analysis contributors to measure hand-eye coordination. They use game-like situations to make the duties related and enjoyable, like catching a ball, pouring from a cup, or hitting a transferring goal, finally figuring out if the vibration intervention improves efficiency over time.
“Nearly universally, all the youngsters I’ve labored with have a form of innate grit,” he says. “I like their resilience, and I hope to study from that in no matter little means I can.”
The examine, made attainable by way of an NIH grant, is 20 years within the making.
After Modlesky earned his doctorate in train science from UGA in 2002, he joined the College of Delaware, the place he helped develop new approaches for working with kids with CP.
“In case you have an damage to the mind, relying on the way it occurred, it might have an effect on different areas. It could impression your habits and sensitivities, trigger schooling delays,” Modlesky says.
Final 12 months, Noah’s mother and father found that he struggled with studying. Testing revealed that he might have dyslexia.

“As a mother, you’re all the time questioning, is the CP inflicting this, and the way else is it manifesting?” Cindy says. “Now we have to do further digging to determine what’s going on in his mind.”
In 2017, Modlesky returned to his alma mater as a college member to proceed pursuing his work by way of an endowed professorship. The scientific trial employs child-friendly practices he helped develop through the years, together with particular MRI methods.
“To make small steps in our analysis takes numerous effort, thought, consideration to particulars, and persistence,” Modlesky says.
Dwelling with cerebral palsy takes that too. However Noah isn’t fazed. When he leaves the lab, he’s headed to check out for his college’s journey baseball group. And he’s able to hit it out of the park.
