X-tension is first to market with the development of post fitting/ fabrication dorsiflexion limiter for custom AFOs. It is designed to prevent drop off at terminal stance by resisting (Dynamic X-tension) or stopping (Static X-tension) tibial progression over the foot.
X-tension bands come in Dynamic or Static options in both pediatric and adult sizes.
Dynamic X-tension bands resist dorsiflexion and generate plantar flexion assistance resulting in: increased third rocker power, contralateral step length, and single limb stability. Resistance is adjusted by selecting different thicknesses. Adult thicknesses are 1/8", 5/32", 3/16", and 1/4". Pediatric thicknesses are 3/32", 1/8", 5/32", and 3/16".
Static X-tension bands come in one thickness and rigidly lock the AFO.
As part of LaunchPad's TRIO innovations, X-tension works in combinations with snapstop and pivot ankle joints to achieve desired shank-to-floor alignments and tuning optimization.
Consider treating those sagittal plane compensations with knee extension, and flexion deficits, by increasing single limb stance stability and overall ambulatory confidence in your patient.
Dynamic X-Tension
Benefits:
Resist tibial progression (dorsiflexion) through stance phase transitions over the foot
Increases 3rd rocker power
Increases contralateral step length
Tunable resistance (4 Adult, 4 Pediatric thicknesses)
Indications:
Externally rotated foot projection angles
Decreased 3rd rocker power
Lack of tibial progression
Shortened contralateral step length
Mild crouch throughout stance phase
Slow cadence
Static X-Tension
Benefits:
Rigidly locks the AFO
Stops dorsiflexion through stance phase
Indications:
Recurvatum
Knee flexion instability
Lack of tibial progression
Shortened contralateral step length
Externally rotated foot projection angles
Decreased single limb stance stability
Decreased 3rd rocker power
Slow cadence
Suggested L-Code: L2220 x2
Product Highlights
General:
No other comparable product on the market
Reimbursable as L2220 (x2) - $77.14 per joint ($154.28 total)
Designed to work with snapstop
Pediatric and Adult sizes
Simple post fitting adjustment
4 thicknesses provide increasing resistance
Static X-tension provides rigid support to make your orthosis perform more like a solid AFO than an articulated AFO. Transition to an articulated AFO is a simple, in clinic, process
Dynamic X-tensions are made of a tough, durable material that resists cutting and will not become brittle
Static X-tensions are made of a polymer encapsulated nylon webbing that adds static resistance to dorsiflexion
Pediatric X-tensions are rated for over 700 lbs of force
Adult X-tensions are rated for over 1100 lbs of force
Fabrication:
This product needs to be installed with tension on it. Since there is always some play when using rivets, be sure to follow the guidelines related to locating the attachment holes
Dynamic X-tensions use standard speedy rivets
Static X-tensions need stronger rivets - copper is recommended
Static X-tensions are not intended to be used as a “check cord”. They should be installed without any slack.
Clinical:
Assist in stabilizing sagittal plane knee instabilities
Increases patient confidence to advance the knee over the foot by resisting dorsiflexion
Improves push off at terminal stance
Increases step length and cadence
Resolves externally rotated foot projections (excessive toe-out)
Post-fabrication tool for optimizing gait performance
