How is This Going to Help Me?

Every day we stand, sit, climb stairs, walk and ideally exercise. Some of us do these activities effortlessly while others cannot due to stiff or frozen knee joints. If your knee has limited range of motion or joint stiffness and is causing frustration with daily activities, forcing you to sit on the sidelines or experience pain, you know that’s not the way it ought to be. Using the Knee Dynasplint® System at home in conjunction with your physical therapy program will provide the combination to help get you moving freely again.

The technology and mechanics behind each Dynasplint® System are designed to mimic a therapist’s hands, only better, as the tension of the Dynasplint® System is reproducible each and every day and evenly distributed every time you wear your splint. Think of a rubber band that you expand and snap for the first time. Once released, it snaps back to the original size. But, if you take the rubber band and place it on your car visor for the whole summer, after removing it you’ll see that it’s permanently changed. That’s what happens when you wear your Dynasplint® System.

Here’s the good news: clinical studies have demonstrated a 53% average reduction in rehabilitation time and cost with the use of Dynasplint® Systems in conjunction with physical therapy. Over 400,000 patients have been successfully treated with Dynasplint® Systems. Read the testimonial on the left to be encouraged by another’s success story.  

What to Expect

When your doctor orders the Dynasplint® System for you, a consultant will meet you at the doctor’s or therapists’ office. They will complete the rental agreement, get your insurance information and then custom fit the unit to your knee. They will instruct you how and when to wear your Dynasplint® System. It is always worn when you are relaxed and inactive, perhaps while watching TV or sleeping. It will feel a bit different at first, but not painful. Relax into the stretch.

You will experience some mild post-wear stiffness, and this is used as a measuring stick. Your consultant will check with you by phone the day following your fitting, and then see you in person in about one week. Press PLAY on the video below to see how to apply and wear your Dynasplint® System.
 

The Rebound Effect

"High-force, short-duration stretching favors recoverable, elastictissue deformation, whereas low-force, long-duration stretching enhances permanent plastic deformation... In the clinical setting, high force application has a greater risk of causing pain and possibly rupture of tissue.*" Dynasplint® Systems improve range of motion by creating permanent, non-traumatic tissue elongation and remodeling, thus virtually eliminating the range of motion rebound effect often observed in the clinical setting.*

Patient Wearing Protocol

Please review the tension your Dynasplint® consultant set for you initially.

In the beginning, the splint should be worn for 2-4 hours.

Do not increase the tension until you can tolerate overnight wear. Time is the most important factor and your first goal should be 6-8 hours of pain free wear.

After achieving this time goal, when you take the splint off if you have less than 1 hour of post-wear stiffness, turn tension up by one on both sides.

However if you are unable to wear the splint for a prolonged period of time, decrease the tension by a half to one full turn.

During the process of regaining your range of motion, if you have any question or concerns contact your Dynasplint® consultant.
