Muscle control is fundamental to movement

Activcore applies a unique neuromuscular approach that gets to the underlying root cause of your pain and movement limitations. Known as Redcord, this tool and technique takes suspension exercise to new heights so that you can bridge the gaps between injury, healing and optimal fitness.

Originating in Norway in 1991, Redcord has since been developed and practiced by elite professionals across the world. It has also been peer-reviewed with over 100 research studies in industry-approved publications such as SPINE, Journal of Physical Therapy Science, Journal of Biomechanics, Journal of Human Kinetics, and Journal of Dance Medicine and Science.

Here's how the science behind it works...

The Problem


Many physical events (injury, illness, surgery, pregnancy, etc.) can alter your brain’s capacity to switch on the right muscles, at the right time, and with the right amount of strength. Known as neuromuscular deactivation, this process involves a loss of signals to the smaller muscles that help stabilize your joints. In turn, the larger muscles tend to take over and compensate. It is this physical imbalance that creates a vicious cycle of abnormal movement patterns, postural alignment changes, and chronic muscle guarding and pain.

Neuromuscular deactivation impairs not just how you move, but also how you recover from injury and trauma. It can even disrupt the way you regulate normal bodily processes like voiding urine (i.e., pelvic floor dysfunction).

The Solution


Neuromuscular activation helps break the pain cycle by restoring the underlying muscle control associated with the root cause of your movement dysfunction. It is like flipping on a light switch to muscles that have dimmed due to pain, injury and inactivity.

Redcord is the ideal system for delivering neuromuscular activation. Similar to floating in water, there are slings and bungee cords to assist you through each exercise. This gravity-free environment helps you safely regain muscle control, without any interference of pain or compensation. (Yes, it is painless!)

Suspension type exercises challenge your mind and body. They require core strength, joint stability, and quality of motion across entire chains of muscles (myofascial chains). Some examples of exercises include push ups, pull ups, bridges, planks, and lunges. These are all weight bearing (closed-kinetic-chain) exercises that demand precise muscle control.

When administering neuromuscular activation, it is key to find the perfect balance of "control versus instability" during each movement. That's where the bungee-assistance comes in. You should feel like you're turning back on (re-activating) muscles but without aggravating your symptoms.

Redcord gets results faster than traditional PT and strength training. The difference is neurological. When your mind and body are fully connected, the effects are unrivaled.

NOTE:  Oftentimes you will see us shaking the red ropes (called perturbation) to enhance the level of neuromuscular stimulation applied.

Activcore Success Stories

What are our clients saying about us?

When I first met Bryan Lynd at Activcore my goal was clear: to walk onto the first tee at the senior men’s club championship as a 55 year old and have my competitors be intimidated by having to play such a youthful and athletic golfer. Not only did I achieve this, but I won the championship. Working with Bryan I was able to overcome a labral tear in my shoulder and avoid having to get surgery. Using the Redcord system I have been able to strengthen my core and continue to improve my golf game as I get older.

Activcore is unlike anything I have ever experienced. One patient, one provider, one hour – one at a time, every time. If you’re serious about your physical therapy and recovery, this is the only place to go!


I was looking for assistance with my golf clients who were dealing with pain while trying to play. Luckily I met Bryan, and after talking with and being treated by him I was very confident in his abilities as a therapist and was able to refer my clients to him. From there, we formed a partnership in which we put clients through the TPI golf mobility screen, as well as a TPI performance screen. Thanks to Bryan and his extremely detailed work assessing movement, pain, and dysfunction, our clients had a detailed plan in place from the very first assessment.

Keiran Halton, Golf Performance Coach

Partnering with a TPI Medical Professional has been a huge benefit in helping my students improve their swing. Everyone's physical make up is different, so it is imperative to understand the limitations of my students. By partnering with a therapist, we can discuss what needs to be done in order to help a student with their game. The TPI approach to instruction is vital. Having Dr. Bryan Lynd in my corner has helped take my instruction to another level!
