Storm Lake area teen cancer survivor walks with new technology at BVRMC

Amber Chrischilles | June 18th, 2024

After surviving a brain tumor, 17-year-old Alex Kron from Schaller, Iowa, is walking with newfound stability thanks to a cutting-edge device recommended by her physical therapist at Buena Vista Regional Medical Center.

At just 12-years-old, Alex was diagnosed with a brain tumor and underwent a year and a half of chemotherapy and radiation treatments. Today, she is in remission.

Despite beating cancer, her treatments caused her to struggle with severe mobility issues, resulting in unsteadiness on her feet. This inhibited her capability to live life to the fullest, affecting her ability to move around the school hallways, wear shoes of her choice and play volleyball.

Grace Weiland, a physical therapist at Buena Vista Regional Medical Center, suggested that Alex try the Bioness L300 Go®, an electrical stimulation device that improves mobility and gait.

The L300 Go uses functional electrical stimulation (FES) to help correct foot drop and thigh weakness in people coping with the effects of stroke, multiple sclerosis, and other medical conditions. The device detects gait irregularities and then deploys FES to the weakened or paralyzed limb so users can lift their feet properly when they walk. This technology can enhance walking speed, balance, and overall confidence in movement.

When being fitted for the L300 Go, it was the first time her parents saw her lift her toes when walking. The initial breakthrough was an emotional moment, moving her father to tears.

Within a few months, Alex no longer needs to rely on a walker to get around. “It doesn’t hurt anymore and I feel like I have my balance,” says Alex Kron.

From being unable to walk through the school hallways comfortably or confidently out of fear of being bumped and losing her balance, Alex has since been able to go to prom in cute shoes and walk the promenade.

“Now, she is walking rather quickly without a walker, can carry her backpack and can use stairs,” says Weiland. “I’m not worried about her balance, and she can start working on running and sports.”

Alex looks to take her next steps in life by attending Buena Vista University in the fall where she will study pre-med in hopes to one day treat childhood cancer, a passion that was inspired by her oncologists.
