WINDSOR — In 2013, Kiel Alarcon was working as a communication assistant at Dartmouth School in Hanover, New Hampshire, and commuted to work day by day by bicycle from his residence in Windsor, which is greater than 40 miles round-trip, as a part of a nationwide bicycling problem. On a type of rides, Alarcon was biking up a hill close to the Hanover Nation Membership golf course when he felt what he thought on the time was a muscle spasm or pinched nerve in his again.
“I had weak point in my legs, my limbs had been going (numb) after which coming again, it was very weird,” Alarcon mentioned.
He mentioned docs at Mt. Ascutney Hospital and Well being Heart in Windsor instructed him he’d had a panic assault, which he accepted as a result of he’d by no means skilled one earlier than and didn’t know the signs. However when his mom checked in on him a day later and found he hadn’t wanted to make use of the toilet since he’d left the hospital, they went to the Dartmouth Hitchcock Medical Heart in Lebanon, New Hampshire, for additional exams.
Urinary retention is a symptom of spinal wire accidents, and Alarcon mentioned medical employees at DHMC drained two liters of urine from his physique that day. An MRI confirmed the injury: a tumor rising on his backbone had ruptured and bled down his spinal wire.
Surgical procedure to take away the benign tumor was profitable, however the injury executed to Alarcon’s physique was important. He can not really feel something beneath his chest and wishes the help of a strolling cane to maneuver round.
However over the previous two years, Alarcon has developed and constructed his personal robotic leg brace that’s helped him stroll with out the necessity for the cane and even helped him summit Mount Ascutney. The brace, which Alarcon mentioned remains to be a piece in progress, began off as a interest meant to go the time as he adjusted to the modifications in his life after the harm.
He mentioned the early days following his harm had been “torturous” and “like hell.” Self-described as somebody who all the time feels the should be doing one thing, Alarcon was compelled to remain busy.
He started educating himself code, partially as a result of he wished to develop a marketable talent he might handle from his mattress.
Alarcon has wished to discover a new job — his place at Dartmouth was defunded in 2014 — but it surely’s tough. He at the moment receives incapacity funds from Dartmouth, and if he acquired a brand new job and it didn’t work out, he wouldn’t have the ability to obtain these funds once more.
He can also’t take a part-time job and work his method up as a result of he’d must work 40 hours per week simply to maintain his medical health insurance, he mentioned, which is a necessity due to the precise objects he wants on a day-to-day foundation like catheters.
One other issue that hurts his job prospects is the truth that he additionally has chronically low blood stress due to the harm, which he calls the worst a part of the ordeal and the factor that limits him greater than his mobility points.
“I can solely be upright for like, two or three hours at a time, if I’m actually pushing it, after which I must relaxation,” Alarcon mentioned. “I principally spend my days within the recliner.”
His nights are sometimes spent with a guitar in his palms. Alarcon is a founding member of What Doth Life, a collective/co-op of native bands based mostly in Windsor, and he performs guitar in 5 bands related to the group.
Alarcon, 38, minored in music at Castleton College and mentioned one fallout from wanting to remain busy via his incapacity was that he “ended up becoming a member of everybody’s band” when requested. Band practices and reveals are probably the most strenuous issues he has to do, as he’s typically standing whereas taking part in guitar for hours at a time.

Alarcon actively looked for a treatment for his incapacity. He tried entering into medical trials for stem cell therapy, he mentioned, however was denied.
He seemed into exoskeleton fits and had a session for a leg brace referred to as a “C-brace,” however discovered that his motion points posed a selected downside that the brace couldn’t assist treatment. Exoskeleton fits are additionally extremely costly, costing within the neighborhood of $85,000, one thing Alarcon couldn’t afford.
“(Leg braces) all appear to work by holding your weight, (however) I can push off, I can kick out with this foot,” Alarcon mentioned. “I simply can’t carry it again in.”
He additionally makes use of a foot-drop brace, which helps forestall his foot from inverting throughout strolling, as a result of he can push his toes out however can’t carry his foot again up.
Annoyed by the shortage of options on the market, Alarcon determined early final 12 months he’d attempt to construct his personal leg brace. He’d developed a number of concepts after years of researching completely different leg braces and wished to present constructing one which suited his particular wants a shot.
He’s acquired one design, consisting of an outdated knee brace, a servo motor, pulleys, two buck converters that assist regulate voltage output, a microchip and about 100 traces of Python code that’s powered by a drill battery, up and working.
Hooked up to the brace is an object-acceleration sensor, referred to as an accelerometer, that detects the angle his leg is at whereas strolling and helps him repeat his strolling gait. As he swings his arm ahead, it tells his knee to bend, and because it swings ahead the angle modifications till it tells the knee to straighten once more.
Alarcon mentioned he’s by no means taken a pc science course in his life, so there was a variety of trial and error concerned. He burned via a number of pc boards as a result of the battery was outputting too excessive a voltage, however the buck converters later helped treatment that.
He mentioned there’s extra work to be executed because it’s troublesome for him to make use of going up uneven terrain and it must be lined up completely together with his leg or else it doesn’t bend as a lot because it must. The accelerometer has a handbook mode, which he used whereas climbing Mount Ascutney in October of this 12 months.
“Proper now it’s actually solely good for shifting ahead,” Alarcon mentioned. “It’s not nice for simply stepping round or turning.”
Altogether, Alarcon mentioned the robotic brace was comparatively cheap to construct at round $200. That’s not all he spent as a result of he went via different designs and elements, like utilizing a muscle sensor on his thigh that may react to his mind signaling his thigh muscle to maneuver.
As a result of he’s been strolling with a crutch for thus lengthy, Alarcon mentioned, he needed to relearn stroll usually whereas sporting it, noting that whereas utilizing the crutch he developed a behavior of swinging his leg out.
Alarcon’s journey up Ascutney, which began on the parking zone close to the summit as a result of he was involved his blood stress could be a difficulty if he began the hike any decrease down, had him traversing over rocks and large tree roots. He’s additionally used the brace to go on walks in Windsor and round Lake Runnemede.
He mentioned the primary few instances he took the robotic brace for a spin made him really feel a bit uncomfortable.
“Oh my god, initially (this) feels very bizarre,” Alarcon remembers pondering. “As a result of I haven’t been capable of have a traditional strolling gait, and I used to be making an attempt to be very cautious about not swinging my hip out or climbing my hip up — but it surely felt good, not solely bodily however (additionally) I used to be making progress.”
When he began engaged on the robotic brace, Alarcon didn’t count on to make it this far. He’s not very self-congratulatory by nature, he mentioned, however enjoys studying new abilities and problem-solving. Engaged on brace designs and studying code from the consolation of his recliner was a solution to go the time.
He subsequent needs to make use of the brace to stroll via Paradise Park, although he’s ready for a drier day (there have been repeated rain showers in Windsor on the day of the interview) because the robotic brace isn’t waterproof, which is one other factor he’s engaged on.
Alarcon mentioned he isn’t thinking about promoting or patenting his robotic brace. He open-sourced the design and code on GitHub and has gotten optimistic suggestions from folks. He mentioned he hasn’t heard from different folks with disabilities, which is what he needs as a result of he hopes his work can assist another person sometime.
“Doing this was actually simply so I can stroll, that’s the reward,” Alarcon mentioned. “… I simply need to have the ability to doc all of it and, if it helps another person on the market, nice.”
