GS Analyser 

How it works.

The GS Analyser is a highly accurate, objective measurement and recording system for neuromusculoskeletal assessment and rehabilitation.  The GS Analyser is designed to measure the isometric voluntary muscle contractions of the body’s muscle groups.  This can be done maximally to measure a peak force, sub maximally to measure a fatigue rating, or against a template to perform rehabilitation.  

It is vital to isolate the muscle group being assessed, minimising recruitment, and ensuring that the GS Gatherer is measuring the isometric force; to do this, the GS Analyser utilises a range of positions for the client.

Back to the basics

Issac Newton's third law states that for every action (force) there is an equal and opposite reaction.  In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.  This is the fundamental principle behind the GS Analyser.

Lets apply this law to the GS Analyser.  Watch the video on the right.  The user (in white) is object A.  Through the GS Analyser and Harness, object A is applying a force to the client's neck.  The client is object B.  Object B exerts an equal and opposite force to that applied by object A.  The force exerted by the client (B) is recorded using the GS Analyser.  When the force applied by the user (A) becomes too great for client (B) to overcome, you have demonstrated the maximum force the user can produce at that position.

Neuromusculoskeletal - What on earth?

A long and complicated word which you will have no doubt seen written a few times on this website.  But what does it mean?  The terms attempts to encapsulates the idea the your bones, muscles and nerves all work together as one unit.  You may have heard the term musculoskeletal.  Simply, "Musculo" - muscles and "Skeletal" - skeleton/bones.  Therefore a term referring the muscles attached to your bones.  "Neuro" refers to the nerves which then control the muscles, which then move the bones.  The GS Analyser is an assessment tool of not just your muscles and bones (musculoskeletal), but also of the nerves which move the muscles - hence neuromusculoskeletal analysis.

 
 
 

Rehabilitation

The GS Analysis Suite has unique training templates that are derived from the test results. This means each rehabilitative intervention is fact based and does not rely on “expert opinion” or guess work.  This assures safe and appropriate fast rehabilitation to the physical therapy profession and assurances to the surgical and medical specialists.  Collation of this data will lead to defining clinical outcomes and best practice recommendations for diagnosis, management and return to full health.  The image below shows a typical rehabilitation template for shoulder adduction.  Similar assessment fatigue, the user must match the trace with the black line given.

The Technical Stuff

The GS Analyser comprises of a bi-directional load cell, a device that can measure load (force) in two directions (compression and tensile forces).

The load cell itself is a highly specialised piezoelectric sensor, a device that uses the piezoelectric effect to measure force.  Changes in force are converted into an electrical charge which is then transmitted via radio-frequency to the paired computer and displayed on the GS Analysis Suite.
