Proving that she’d much rather focus on her dancing than walking, Miller showed off her best classical ballet-styled arm movements as she stood up from her wheelchair in avideo on InstagramWednesday afternoon.
Insiders previously told PEOPLE that while the star was “getting a little stronger every day,” there was initially concern shemay never walk againdue to her health issues.
Despite that, Miller has remained focused on her journey to recovery and oftenshares photos to social mediaof her rehabilitation plans and exercises, showing off the progress that she has made following her initial cancer diagnosis last year.
In April, one day after undergoingemergency surgeryfor what was initially thought to be a spinal infection, the reality star — who wasreleased from prisonin March — was preliminarily diagnosed with non-Hodgkin’s lymphoma, a cancer that develops in the lymphatic system.
“It was not an infection, it was a type of a non-Hodgkin’s lymphoma — it’s a type of a cancer,” said Dr. Hooman M. Melamed, an orthopedic spine surgeon at Cedar Sinai Marina Del Rey Hospital who treated the star.
“We’re getting an oncologist involved and we have to figure out what the next steps are as far as chemotherapy or radiation or more spine surgery. Depending on the tumor type, depending on the sensitivity of the tumor — it just depends the type but I feel more than yes, she will undergo chemotherapy or radiation,” Dr. Melamed added.

Miller went into the emergency room after she experienced “excruciating neck pain” and weakness in her arm, and after her condition deteriorated over the next couple days, Dr. Melamed performed emergency surgery for a multi-level laminectomy.
“If we didn’t do something, she was going to die,” Dr. Melamed told PEOPLE. “Her blood pressure was bottoming out. She was not doing well.”
Since then, Miller has beenreceiving chemotherapyand rehabilitation, all of which have been documented via social media. Millerleft her rehabilitation facilityin September.

In addition to recovering, Miller has also been focusing on her return toDance Moms.
More than a month afterteasing her involvementwith the popular series, sheconfirmed on Instagramthat she would return forDance Moms’ upcoming season. “OMG! Can you believe I’m going to film Season 8 of Dance Moms!” shewrote, alongside a shot of herself with a surprised look on her face.
“Yes, it’s official! We begin the end of Jan!” she continued, adding the hashtags #DanceMoms, #Aldcalways and #Thebestityettocome.

Earlier this month, in anexclusive trailer of Lifetime’s upcomingDance Moms Resurrection,the star got candid about her cancer struggle and revealing just how she regained the strength to do what she loves — teach dance.
“I need to get back to teaching and I need to get back to screaming at children,” she added. “I need to get back to my roots. I’m going to take these kids right back to the turf.”

After meeting her new dancers in the studio, Miller revealed that she “fought hard” to overcome the doubt of her return and recovery.
“I have my own personal goals and I have goals for the team. I need to be ready for that first competition,” she added. “We need to make a statement on that stage that the ALDC is back … and watch out!”
