A multi-functional sliding grip exercise device, specifically but not limited to: sliding grip medial pull-ups, sliding grip lateral pull-ups, lower back extension/sit-up assistance exercise. Exercise device will have rotatable rubber pegs attached to horizontal bars to aid in utility. Horizontal bars supporting hand grips will have apertures on its frame; apertures will take on the form of a “T” with arms going vertically down to engage device locking system. Horizontal bar with apertures will have tracks on top surface and bottom surface to support guidance of Hand grips. Horizontal bar with apertures will have a resistance element housed within, preferably but not limited to springs; also housed within bar will be spring caps with an protuberance attached that will make contact with Handgrips appendage to engage springs. Handgrips may have indentations to support lower back bar for lower back extension/sit-up assistance exercise. Device may have adjustable resistance.

A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would inhibit the “side-to-side” movement of the spring within the housing. The stopper has a cone-shaped air-stopping surface providing a valve angle that is different from the valve-seat angle so that either laminar or oscillating flow may be obtained.

A walking assist device has a frame, a pair of right and left arm portions, a pair of right and left grasp portions, wheels including a pair of right and left drive wheels, drive units, a battery, a drive control unit, acting force measurement units that measure acting forces on the grasp portions, and holding units that hold the grasp portions at a predetermined position in the front-rear direction of the arm portions set in advance. The walking assist device travels forward together with a user. The holding units generate a restoring force for returning the grasp portions to the predetermined position. The drive control unit controls the drive units on the basis of acting forces calculated on the basis of detection signals from the acting force measurement units.

A system for performing multi-directional resistance exercises including a handheld exercise device with a handle portion and a weighted portion connected to the handle portion, wherein the handheld exercise device is configured and dimensioned to create an exercise stimulus upon application of a first directional force generated by a muscle or group of muscles of a user, which first directional force is oriented substantially aligned with and opposed to the force of gravity exerted upon the weighted handheld exercise device; and at least one resistance device including a resistance element configured and dimensioned to compress upon application of a force exerted thereon, the at least one resistance device connected to the handheld exercise device to dispose the resistance element at an orientation such that a second directional force applied by a user to compress the resistance element against a surface.

Methods for treating fluid overload in a subject comprise shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local sweating. Methods of the invention allow for removal of excess fluid from the interstitial compartment of the subject and treat fluid overload in the subject. Sweat stimulation systems comprise a chamber and first and second relative humidity sensors. The chamber is sized to fit around a body part of a subject, comprises an inlet and an outlet, and is configured such that air flows through the chamber from the inlet to the outlet. The first relative humidity sensor is operably located inside the inlet, and the second relative humidity sensor is operably located proximate the outlet.

An exercise device includes a resilient compression member configured to resist a compressive force from a user, and a resilient tension member configured to couple to opposing sides of the compression member. The resilient tension member is also configured to form a first portion of a loop around the compression member and the user, and resist a tensile force from the user. The exercise device also includes an extension member configured to connect with opposing ends of the tension member to form a second portion of the loop around the compression member and the user.

A finger-assisted training device and an application method thereof are provided. An electric cylinder drives the sliding sleeve to slide; the sliding sleeve drives two connecting rod mechanisms; the connecting rod mechanism includes four connecting rod assemblies; the connecting rod assembly includes a rocker, a connecting rod and a movable rod; one end of the support is hinged on the support plate, the support is fixed on the support plate; the middle of the rocker is hinged with one end of the connecting rod, and the other end of the connecting rod is hinged with the sliding sleeve; the other end of the rocker is hinged with one end of the movable rod; the other end of the movable rod is fixed with a collar; the fixed arc rod is connected with the movable rod of each link assembly through a spring.

The training apparatus according to an embodiment includes: a support unit; a guide unit fixed on the support unit and including rails which extend in a front-rear direction; a sliding unit which is movable in the front-rear direction along the rails of the guide unit; a pillar-shaped rotation axis fixed on the support unit; a footrest unit which supports a user's foot; a lower support formed below the footrest unit; and a connection rotating unit formed below the footrest unit and connected to the rotation axis of the support unit through insertion to allow the footrest unit to rotate around the rotation axis. A plurality of springs installed inward from two sidewalls of the sliding unit is configured to come into contact with the lower support of the footrest unit and apply pressure from two sides when the footrest unit rotates.
