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.

A stretching apparatus for use during a stretching exercise includes a strap and a ratchet device. The strap is configured to attach to a limb of a user. The strap extends through the ratchet device and the ratchet device controls tension in the strap. The ratchet device is positionable between a ratcheting position and a release position. The ratcheting position prevents movement of the strap in a first direction and allows movement of the strap in a second direction. The release position allows movement of the strap in the first direction. The stretching apparatus also includes a remote trigger connected to the ratchet device to move the ratchet device between the ratcheting position and the release position. The stretching apparatus removably connects to support structures and is adjustable between different positions for different stretching exercises.

A massage machine includes a backrest unit, a massage unit disposed in the backrest unit and a control unit. The massage unit is movable in a height direction and includes a treatment element that applies treatment onto a user, a first sensor configured to detect a first site of the user based on a load received from the user according to the movement of the massage unit and a second sensor configured to detect a second site of the user based on a movement of the treatment element according to the movement of the massage unit. The control unit is configured to control the massage unit so that the first sensor detects the first site of the user during the movement of the massage unit from an initial position, and the second sensor detects the second site of the user during the massage being in progress.

A leg massage machine capable of massaging popliteal fossa contains: a base, two swing arms, a first massager, and a second massager. The base includes a drive motor, and the drive motor has two driving shafts and two actuation blocks. The two actuation blocks have two eccentric posts. A respective one swing arm includes a drive segment and a driven segmenting. The drive segment has a fixing orifice, and a massaging unit is connected on the drive segment. The first massager includes two first protrusions and two first fixing shafts. At least one first protrusion has a first connecting orifice configured to connect with one actuating shaft of the two swing arms. The second massager includes two second protrusions and two second fixing shafts. At least one second protrusion has a second connecting orifice configured to connect with the other actuating shafts of the two swing arms.

A massage chair includes a seat portion, a back portion a leg portion, and a massage carriage configured to move within the seat portion, the back portion, and the leg portion. The massage carriage includes comprises a percussive massage assembly comprising a motor, a reciprocating shaft coupled to the motor and configured to reciprocate in response to activation of the motor, and a reciprocating massage head coupled to the reciprocating shaft. The massage chair also includes a support mechanism associated with the percussive massage assembly. The support mechanism is configured to support a weight of a user of the massage chair, thereby allowing the reciprocating shaft and the reciprocating massage head of the percussive massage assembly to reciprocate.

A method for inducing knee flexion is described that includes securing a knee rehabilitation device to a leg, the rehabilitation device includes a frame with a handle on a proximal end, a pad piece on a distal end, and a strap between the proximal end and the distal end. The method further includes positioning the knee rehabilitation device on the person's leg such that the handle is above a knee on the leg, the pad piece is on an ankle of the leg, and the strap is located behind the person's leg between the knee and ankle. A first force is then applied to the handle in a first direction. The pad piece is actuated in response to the first force to move in a second direction which applies a second force to the ankle of the leg in a direction to cause flexion of the knee.

A toe-tapping exercise machine comprises: a foot rest part having a right foot rest adapted to seat a user's right foot thereon and a left foot rest adapted to seat the user's left foot thereon; and an operating part coupled to the foot rest part to allow toe portions of the foot rest part to tap each other, the operating part comprising: a driving motor for transferring rotating power; a right foot rest operator for receiving the rotating power from the driving motor to operate the right foot rest; and a left foot rest operator for receiving the rotating power from the driving motor to operate the left foot rest, the driving motor being disposed between the right foot rest operator and the left foot rest operator and having rotary shafts extended from both sides thereof.

A spa pool is provided including a pool body, the pool body including a pool bottom and a pool wall together defining a water cavity. The spa pool further includes: an inflatable seat defining therein a second air chamber and disposed in the water cavity; a first nozzle assembly, wherein at least a part of the first nozzle assembly is accommodated within the inflatable seat, and a first end of the first nozzle assembly is in fluid communication with the water cavity. The pool body further includes a fluid pipeline disposed in the first air chamber, the fluid pipeline being in fluid communication with a second end of the first nozzle assembly, so that the first nozzle assembly provides fluid communication between the water cavity and the fluid pipeline.

A decompression device may include a support structure to which a harness and a base may be coupled. A positional motivator may also be coupled to the support structure. The positional motivator may be configured to both change and maintain the distance between the base and portions of the harness. The base may be positioned on a surface or structure, and portions of the harness may be positioned around the body of a user, such as under the arms and around the back. The user may manipulate the positional motivator to position portions of the harness a desired distance from the base. Optionally, the user may then lean forwards with the support structure and the harness will provide additional lift, and therefore decompression, to the body and back of the user.
