Description

 
A Supination Resistance Measuring Device that assists the practitioner to determine that amount of support or arch height needed in an orthotic to reduce patient symptoms.
 
The Keystone device is the first commercially available device for clinicians to quantify the supination resistance value so they can make better clinical decisions and better communicate with other clinicians.
 
USING THE KEYSTONE
With the person standing in their normal angle and base of gait, the strap is placed under the talonavicular joint. To maintain consistent measurements keep the strap vertical and perpendicular to the ground. 
 
Before taking the measurement let the patient know what you’re about to do. Ask the patient to indicate when they feel the first toe and ball of foot beginning to lift from the ground. This is done simultaneously as you observe the first toe and medial column beginning to lift. The two observations should coincide. 
 
Once this point is reached maintain that force for 3 seconds until the Keystone ‘beeps’ and the measurement taken. Record this measurement. 
Push the power button to reset the Keystone and repeat this process 3 times. Average these 3 recordings to get your measurement. 
 
The Keystone device is calibrated to measure forces between 40 and 250 Newtons.  
For clinical ease and practical use - this range is divided into three reading sections: LOW - MODERATE - HARD.
These three force ranges correspond to the arch height (synonymous with the amount of force required to supinate the foot) of the orthotic.
