title: Force production decay rate in Alastik modules.
abstract: The production and decay of forces produced by Alastik modules was studied under conditions simulating clinical usage over time period of 2 hr to 4 weeks. Force decay was moderate and all Kx modules tested produced approximately 1 lb of force at the end of the 4-week test period. Therefore, from a clinical standpoint, modules need not be changed more frequently than once every 4 weeks.
