OUR MISSION

Help People Restore Their Ability to Walk

We are dedicated to creating accessible, home-based solutions that empower individuals to stand, move, and improve their health through walking.

HOW IT ALL STARTED

The Moment That Changed Everything

Our founder, Alan Tholkes—founder of Altimate Medical and creator of the EasyStand, is also a long-time quadriplegic wheelchair user who had a simple goal: he wanted to walk again.

He scheduled an appointment at a rehabilitation center to begin that journey.

A few weeks later, he found himself suspended in a harness over a treadmill, supported by a team of therapists helping guide his legs through the motion of walking. While the process required assistance, the experience was powerful.

For the first time in years, he could feel the rhythm and sensation of walking again—even if only for 20 minutes.

When he returned home, that feeling stayed with him. Energized and encouraged, he wanted to experience it again the next day.

But that wasn’t realistic.

Frequent visits to a rehab facility were not only impractical—they were financially out of reach for consistent, long-term use.

That moment sparked a realization.

Walking isn’t just movement—it’s fundamental to maintaining circulation, muscle health, and overall well-being.

So Alan asked a simple question:

What if people who cannot walk had access to a solution that allowed them to do so safely, independently, and from their own home?

Driven by that vision, he assembled a team of experienced rehabilitation product designers.

Together, they began developing what would become our flagship product: WalkPort.

SUPPORTED WALK STATION

From One Moment to a Mission

That experience didn’t just inspire a product—it defined our mission.

We believe walking is fundamental to long-term health. It supports circulation, preserves muscle function, and improves overall well-being. Yet for many individuals, access to consistent walking therapy is limited by cost, logistics, and availability.

We set out to change that.

Our goal is simple: make the benefits of walking accessible beyond the clinic—bringing safe, supported movement into everyday life.

FUTURE OF SUPPORTED WALKING

A Better Way to Restore Movement

WalkPort was designed to bring the benefits of walking out of the clinic and into everyday life.

Traditional rehabilitation is effective—but often limited by time, cost, and access. WalkPort makes it possible to experience safe, supported walking more consistently, without relying on frequent clinical visits.

By combining thoughtful design with deep clinical insight, WalkPort enables users to:

  • Safely stand and experience supported walking
  • Incorporate movement into daily routines
  • Improve circulation, muscle engagement, and overall well-being
  • Take a more active role in their health and independence

Backed by decades of experience in medical device development and rehabilitation, every WalkPort is built with safety, compliance, and real-world usability in mind.

We’re not just building equipment—we’re creating a more accessible path to movement and quality of life.

WE BELIEVE

The human body can heal itself if given the opportunity. 

Investing in improving health is less costly than caring for illness. 

Lack of mobility is killing people and “walking is man’s best medicine.”

WE VALUE

Treating every customer with care, respect, and a commitment to improving their daily lives.

Strive to make complicated things easier for our customer.

Doing the “right thing” for our customer.

Kevin shares his inspiring full testimony at WalkPort.

We had the privilege of trying out Medthera’s new WalkPort machine for 30 days. First look at this product had me amazed at how compact it is, while adding more natural leg action into the design that can easily be adapted from a 6-foot patient to my 5-foot 2-inch wife. My wife, LuAnne, has been in physical therapy for 36 months. In that time, we have used 3 different styles of machines, most of which required one or two therapists to get her into. One took over 20 minutes to go from wheelchair to harness to the machine. Once in, one of the therapists would control the speed while the other would make sure LuAnne was OK and, in some cases, moving her leg. WalkPort does a fantastic job of addressing all the problems I have seen in the current style of machines on the market today.

The 3 area’s that I feel make it stand out.

1. The design is so easy to adjust to fit the patient. Once set up, the patient can do as much of the transfer from the wheelchair to the WalkPort as their disability will allow. In our case, LuAnne can roll up to the machine and get into the seat on her own. We have to position her right leg, which is paralyzed, into position and secure her foot. Once that is done, she can get herself to a standing position and start the motion of walking with no assistance from us. This allows her to walk for around a half hour quite easily.

2. The motion of the legs, knee and ankle is so close to actual walking movement, helping her re-establish the motor function of walking in her brain. The muscle gain and stamina were rather noticeable every day with major improvements over the course of our time with WalkPort. Towards the end of our 30 days, we had to limit LuAnne to an hour in the evening sessions as she was enjoying it so much.

3. The last and probably most valuable aspect is the attitude/excitement LuAnne expressed. She was incredibly proud of the work she was doing, especially how much of it she could perform unassisted. She always had a bright smile on her face when using the machine. She had gained such a boost in confidence while doing her exercises, from maneuvering around the machine on her own, to holding a standing position, to starting the motion of walking without assistance. She was very empowered seeing how much progress she was making on her own.

The size of this machine is about one-third the size of the other machines we had tried in the past. The first day we were introduced to the machine, LuAnne was in it and walking on her own within minutes. No motors controlling her stride. The enjoyment we saw on her face was so nice to see. Something else my daughter noticed was LuAnne walking forward for a while, then stopping and starting to walk backwards. I am not a therapist, but this seems to be a big deal to me.

In the end, LuAnne was able to gain muscle in her right leg and increase her stamina. We are still working on her walking on her own, but I am sure using this machine will reduce the time it will take to get to the next level of recovery.
