JAS Patient Testimonials
Since starting exercising with the JAS "braces", and under Erick's professional guidance, I have been able to pick up the pace, and accelerate my recovery, as is confirmed during the measurements my physical therapist performs while monitoring progress.
Thanks to JAS, I was able to fully recover and restore my ROM after a complex elbow fracture. I am so grateful, from the bottom of my heart…
The JAS is simply an elegant and patient-friendly method of what a core aspect of physical therapy has been for decades. One of the most difficult and frustrating components of orthopedic aftercare for all professionals is patient compliance. The JAS program is thoughtful, physiology-based, and patient friendly. It is easy for members of a patient’s support system to assist and monitor compliance. That is a big deal.
“Before elbow surgery, I had a range of motion loss of 19 degrees. Post elbow surgery that range of motion loss went up to about 30 degrees. I wear this three times a day, for 30 min at time. This is a really well-designed brace, and I can feel the difference within the first day of use.”
I would like to say thank you. Every time I called, everyone was so helpful. His leg can straighten more and bends better, we just need to get some strength back.
Virginia began using the JAS device in October 2021 and noticed improved mobility within a week. Chuck noticed a slight improvement in her extension very shortly after she started using the device. By mid-November, Virginia was confident enough to take a trip up the coast with her JAS device in tow. For the first time post-op, she was able to hike with her husband to a waterfall!
JAS Knee device has done wonders in getting my ROM back to acceptable levels. Extension is now about 5 degrees and flexion is about 110 plus. I’m confident that I’ll get my extension & flexion even better over the next few months.
