FMR is an acronym that stands for Functional Manual Reaction (TM). Functional Manual Reaction is the name that the Gray Institute uses to describe the application of hands to bone segments in order to facilitate an optimal sequence of motion during a functional movement. FMR is used during our clinical tasks of movement assessment, functional training, and rehabilitation. It can complement all aspects of movement analysis.

It is complementary because it is not a passive technique that exists by itself, but rather a technique used during active movements to enhance the three clinical tasks listed above. FMR is a very powerful and effective tool when utilized during functional movements. However, it cannot be effectively employed without a comprehensive foundation in Applied Functional Science that includes: joint and muscle anatomy, tri-plane muscle function, biomechanics/kinematics, relative joint motions, and inter-segmental dynamics.

FMR can be used to assess movement restrictions caused by muscles and joints. In addition to eliminating identified movement restrictions, it can also be utilized to restore the proper sequencing of bone movements that is essential to effective and efficient task execution. FMR is frequently used to increase the load to a muscle during an eccentric contraction in order to enhance the muscle’s concentric power. Whatever the purpose of the FMR technique, the actual application must be consistent with the principles of function so that the proprioceptive input is genuine. The proprioceptive information (direct by the hands, and indirection through the joint motion and muscle lengthening) must be what the body receives during actual functional activities.

FMR shares some aspects of Proprioceptive Neuromuscular Facilitation (PNF). PNF and FMR emphasize the three-dimensional nature of human movement, the role of hand contact in guiding bone movement, and the potential to increase muscle activation. FMR does not, however, require specific hand placement for efficacy. FMR, in contrast to PNF, is most commonly used with the client in an upright position so that the load and proprioceptive input produced by gravity are consistent with the functional activity.

The forces applied to bones during FMR are relatively gentle and carry little risk because they are consistent with the physiological movement that is occurring. During the FMR techniques, your DHF coach's hands can be placed on adjacent bones, but also can be placed so that they cross multiple joints. Because of this, FMR is not always specific to a particular joint, but it is always specific in each of the three planes to the particular activity, as well as what body parts are creating the motion.

Our 3D Matrix Performance Systems adhere to the principles of Applied Functional Science (AFS). AFS is the convergence of the physical, biological, and behavioral sciences. The 3D Matrix Performance Systems is designed to build a logical and sequential program for the individual. After analyzing your movement through our 3D MAPS screening, your coach will create an environment to expand your functional threshold. Your functional threshold can be defined as your body's ability to successfully perform daily and sport specific tasks at just the right amount and at the right time for you.

Each workout you will perform at the DHF Clinic and on your digital GI App will take you through multiple matrices that are designed for your specific task and goal. A matrix move takes advantage of the physical space surrounding you by exploring motion in three dimensions. In the sagittal plane (forward and backwards), the frontal plane (side to side), and the transverse plane (rotational). Aside from the core purpose of a Matrix (3D Movement), your DHF Coach will tweak or modify each matrix in regards to:

  • environmental tweaks (equipment used)
  • distance moved
  • height
  • rate or speed of motion
  • load enhancement
  • duration

Fundamental movements such as lunges, squats, pushing / pulling, lifting, reaching, locomoting, and verimoting (jumping/hopping) will be utilized from varying starting positions (upright, balance, prone, supine, side lying, sitting, kneeling) and are authentically driven by your feet, hands, eyes, shoulders, and more to achieve:

  • Flexibility & Mobility
  • Stability & Balance
  • Endurance & Sustainability
  • Strength & Power
  • Speed & Reaction
  • Coordination & Agility
