Abstract:
PCT No. PCT/US96/15533 Sec. 371 Date Mar. 24, 1998 Sec. 102(e) Date Mar. 24, 1998 PCT Filed Sep. 27, 1996 PCT Pub. No. WO97/12299 PCT Pub. Date Apr. 3, 1997This invention is an apparatus and method for monitoring and motivating user compliance for orthodontic headgear (24) of the type using a linear spring force module (22). The spring force module (22) includes first (38) and second opposite attachment members that are interconnected to provide spring tension when moved linearly apart. A position sensor (16)(18)(19) detects liner movement between the attachment members. A microprocessor (12) receives signals from the position sensor to determine wear duration, force magnitude, and whether such movement is sufficiently variable to be biological in origin or is attempted mimicry. Multiple determinations made by the processor are recorded over time to provide an evaluation of headgear wear compliance and to provide ongoing motivation for user compliance.
