ARKJ Wedge
Mouth Stretching Device
Designed to treat radiation induced trismus and beyond
ARKJ Wedge — Clinically-informed jaw mobilization, made accessible
-
Clinician-led design: Developed by a speech-language pathologist specializing in head & neck oncology, based on daily patient needs (comfort, controllable progression, home adherence).
-
Engineer-tested: Prototypes underwent bench testing with a digital force gauge to characterize resistance behavior and durability; photos below document the test setup.
-
Evidence-based practice: Our product philosophy is informed by current literature on jaw stretching devices evaluating device forces/kinetics.
-
Practical features: graduated resistance, stable grip surfaces, simple cleaning protocols, and education written by the treating SLP.
-
Access & equity: Direct-to-consumer pricing lowers costs for patients while supporting clinic-based programs.
-
Status: Patent pending.
Intended use
Adjunct for progressive passive range-of-motion to support management of trismus and jaw stiffness; recommend integration with your clinic’s home exercise program and monitoring.
Package options
Single-patient kits and clinic bundles; training resources available.
- The ARKJ Wedge is a home exercise aid for jaw range-of-motion. It is not a substitute for medical care. Always consult your oncology/rehab team before use, especially during active treatment or if pain worsens.
