Intervention

Device:
Knee Extension Dynasplint
Dynamic Splinting utilizes the protocols of Low-Load, Prolonged-Duration Stretch (LLPS) with calibrated, adjustable tension to increase the Total End Range Time (TERT) to reduce contracture. The Knee Extension Dynasplint for the Experimental group will have tension chambers delivering therapeutic treatment from the device.
