Staff Sgt. Sebastiana Lopez Arellano was riding a motorcycle when an animal scurried onto the road, causing her to swerve and hit a curb. As she high-sided over her bike, the momentum catapulted her body into a tree. The impact severed her right leg.

“I thought I was going to die,” the 25-year-old Airman said of the February 2015 crash in Charleston, South Carolina.

While at the hospital, she did briefly die twice before and during a coma that lasted for about a month.

The diagnosis was grim for Lopez, now a patient at the Walter Reed National Military Medical Center. Besides an amputated leg, she had several broken bones, ripped arteries and organs, nerve damage and serious hand injuries that prevent her from fully opening them.

“‘This is a really bad nightmare,’” she recalled telling herself when she regained consciousness. “I felt very hopeless. I was thinking that I could never do anything again.”

As she recovered, the former C-17 Globemaster III crew chief found comfort in sports and fitness. A year after her crash, she competed in the Air Force Trials for wounded warriors and gained confidence by earning invitations to the Invictus and Warrior Games.

“It showed me that I could do this,” she said. “That’s when the old me came out. It was a turning point for me.”

In early May, she captured two gold medals in rugby and hand cycling, and three silvers in shotput, discus and in another hand cycling event at the Invictus Games. She planned to add more hardware at the Warrior Games.

Lopez contends in several other sports, such as wheelchair racing, hand cycling, shotput, shooting, and sitting volleyball — the most difficult sport for her.

In 2013 and 2014, she was selected to the All-Air Force volleyball team after playing college volleyball in her hometown of San Bernardino, California. But the extensive injuries have since prevented her from returning to form.

“It’s very frustrating to me because I can’t use my hands,” she said. “They are one of the most important things in volleyball.”

Lopez tries to keep a positive outlook as she progresses with physical and occupational therapy that help her improve in sporting events.

“It opened up a lot of doors for me,” she said of her participation in adaptive sports. “I feel that the opportunities are endless.”

Walter Reed’s Military Advanced Training Center, where Lopez and other amputees receive state-of-the-art care, uses a sports medicine model with various activities and exercise equipment as part of the rehabilitation process.

“I think sports are a great way to physically and mentally challenge yourself,” said Annemarie Orr, an occupational therapist at the center. “For a lot of our patients who are young, active and highly motivated individuals, it’s a way to push them to the next level in all aspects of their rehab.”

Orr and other therapists aim to inspire amputee patients by instilling a sense of independence after their traumatic experiences.

“Despite all of the challenges they are faced with, they continue to succeed,” Orr said, who also teaches basic daily living tasks to help amputees be self-sufficient.

Hindered by her injuries, Lopez had to relearn small tasks like putting on her makeup, handwriting and even dressing.

“The small victories can add up to a huge victory,” she said, smiling.

Her therapy has now advanced to the dance floor. In the back of the training center, Lopez and a dance instructor often practice moves that would be hard for many two-legged people.

The Mexican-American Airman is no stranger to either ballroom dancing or the lively beats of Latin dancing.

“Merengue is fun,” Lopez said of the festive Latin dance that heavily relies on hip motion. “It’s in my blood.”

Having fun is important to Lopez, who has struggled with anxious thoughts when out in public with her prosthetic leg.

“At first, I felt like everyone was judging me,” she said. “Now I don’t care.”

She also makes an effort not to dwell on what lies ahead in life. By staying in the present, Lopez said she and other amputees can conquer tasks that were once thought out of reach.

“Don’t overwhelm yourself thinking about the future,” she said. “Focus on your recovery and just take it one day at a time. As long as you put the hard work into it, you can do whatever you want.”
