With its cutting-edge design and advanced technology, the Interpod Keystone provides unmatched support and comfort for patients, leading to better treatment outcomes and increased patient satisfaction.
 The Interpod Keystone, a valuable tool in the field of orthotics.
Features:
Supination Resistance Assessment: The Interpod Keystone is specifically designed to measure supination resistance. It provides an objective assessment of the foot’s resistance to supination.
Objective Readings: By using the Keystone, practitioners can obtain objective measurements. These readings help determine the optimal level of orthotic support required to alleviate patient symptoms.
Polypropylene Construction: The device is constructed from durable polypropylene material.
Simplified Prescription: It simplifies the prescription process by providing quantifiable data.
Customizable: The Keystone is adaptable and can be customized to fit individual foot contours.
Communication Tool: Practitioners can use the technology to communicate and compare results with other professionals.
 
Benefits:
Precision: The objective measurements remove guesswork, ensuring accurate orthotic support.
Improved Outcomes: Evaluating the level of orthotic support is crucial for successful patient outcomes.
Collaboration: Practitioners can discuss patient cases and compare results with colleagues.
Supination Control: The Keystone helps address supination moments during gait.
 
Common Uses:
Orthotic Prescription: Determine the appropriate level of orthotic support for individual patients.
Foot Symptom Management: Assess and manage foot-related symptoms effectively.
Sports and Musculoskeletal Injuries: Useful for athletes and individuals with specific foot biomechanics.
Objective Practice: Enhance clinical practice by incorporating objective measurements.

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.
 
Instructions on how to use are also supplied with each device.
