Claim 6:
7. A method for adjusting user-interface height during usage of a differential air pressure (DAP) system by a user, the DAP system comprising:
a platform having a cover defining an access opening into an internal cavity defined within the platform;
a treadmill retained by the platform within in the internal cavity, the treadmill substantially exposing a top treadmill surface through the access opening;
an inflatable enclosure having a base defining a base opening secured to the cover about the access opening and extending upward to a top opening defined therethrough;
a pair of powered vertical lifts connected to opposite sides of the platform along a longitudinal mid-region proximate the top opening, each having a vertically drivable carriage;
a seal frame having a pair of opposite restraint connectors;
a pair of flexible tensile restraints, each attached at one end to a corresponding restraint connector and at an opposite end to a corresponding carriage; and
a user seal worn by a user having a user seal interface configured for attaching to the inflatable enclosure at the top opening when the user extends through the top opening and engages the top treadmill surface for using the DAP system in an unweighting condition;, the method comprising:
determining a user seal interface height for the user;
determining a usage carriage height based on the user seal interface height for the user, the user seal interface height different from the usage carriage height;
raising each carriage to a user seal attachment position higher than the usage carriage height for attachment of the user seal interface to the enclosure;
lowering each carriage to the usage carriage height;
confirming inflation conditions are met including attachment of the user seal interface to the inflatable enclosure at the top opening;
inflating the enclosure to an inflated condition; and
restraining the user seal interface at the user seal interface height including restraining the seal frame at a seal frame height according to the usage carriage height.
