Abstract
Described herein are various embodiments of differential air pressure systems and methods of using such systems. The differential air pressure system may comprise a chamber configured to receive a portion of a user's lower body and to create an air pressure differential upon the user's body. The differential air pressure system may further comprise a user seal that seal the pressure chamber to the user's body. The height of the user seal may be adjusted to accommodate users with various body heights.
Claims9
A differential air pressure system, comprising:
- a positive pressure chamber having a sealing interface to form a pressure seal about a portion of a user;
- a treadmill positioned relative to the positive pressure chamber wherein a portion of a belt of the treadmill is in position below the sealing interface which allows a user coupled to the sealing interface to interact with the treadmill belt while experiencing an unweighting effect from operation of the positive pressure chamber;
- a height adjustment assembly attached to a portion of the positive pressure chamber wherein movement of the height adjustment assembly adjusts the spacing between the sealing interface and the treadmill belt to accommodate the user;
- and
- a control panel for initiating and adjusting the pressure within the differential air pressure system.
